Received the Audiophile Golden Earphone Award for a "truly exceptional audio presentation".

The audio pickup coil is connected to a telephone receiver (earphone) (T) which converts the current pulse to sound. The radio signal from a spark gap transmitter consisted of pulses of radio waves (damped waves) which repeated at an audio rate, around several hundred per second. Each pulse of radio waves produced a pulse of current in the earphone, so the signal sounded like a musical tone or buzz in the earphone.

When this varying current passes through the earphone voice coil, it creates a varying magnetic field which pulls on the earphone diaphragm, causing it to vibrate and produce sound waves. Crystal radios had no amplifying components to increase the loudness of the radio signal; the sound power produced by the earphone came solely from the radio waves of the radio station being received, intercepted by the antenna. Therefore, the sensitivity of the detector was a major factor determining the sensitivity and reception range of the receiver, motivating much research into finding sensitive detectors. In addition to its main use in crystal radios, crystal detectors were also used as radio wave detectors in scientific experiments, in which the DC output current of the detector was registered by a sensitive galvanometer, and in test instruments such as wavemeters used to calibrate the frequency of radio transmitters.

Development work on the design of the iPod Nano started only nine months before its launch date. The Nano was launched in two colors (black and white) with two available sizes: 2 GB (roughly 500 songs) and 4 GB (1000 songs). On February 7, 2006, Apple updated the lineup with the 1 GB model (240 songs). Apple also released some accessories, including armbands and silicone "tubes" designed to bring color to the Nano and protect it from scratches, as well as a combination lanyard- earphone accessory that hangs around the neck and avoids the problem of tangled earphone cords.

In many circuits, the selectivity was improved by connecting the detector and earphone circuit to a tap across only a fraction of the coil's turns. This reduced the impedance loading of the tuned circuit, as well as improving the impedance match with the detector.

Bob and Debra Deyan won the Lifetime Achievement Award in 2013 from the Audio Publishers Association, for their work in helping to pioneer the audiobook industry.

If the amplifier is significantly nonlinear, intermodulation distortion will occur and the audio signal will modulate the RF signal, resulting in audio feedback which can cause a shrieking in the earphone. The presence of the audio return circuit from the amplifier output to input made the reflex circuit vulnerable to such parasitic oscillation problems.

During his career he has narrated more than five hundred audiobooks. In recognition of his narration work, he received the Audie Award for best history book narration in 2010, as well as multiple AudioFile Earphone Awards.

Diagram showing how a crystal detector works The contact between two dissimilar materials at the surface of the detector's semiconducting crystal forms a crude semiconductor diode, which acts as a rectifier, conducting electric current in only one direction and resisting current flowing in the other direction. In a crystal radio, it was connected between the tuned circuit, which passed on the oscillating current induced in the antenna from the desired radio station, and the earphone. Its function was to act as a demodulator, rectifying the radio signal, converting it from alternating current to a pulsing direct current, to extract the audio signal (modulation) from the radio frequency carrier wave. The audio frequency current produced by the detector passed through the earphone causing the earphone's diaphragm to vibrate, pushing on the air to create sound waves.

Pickard, an engineer with the American Wireless Telephone and Telegraph Co. invented the rectifying contact detector, discovering rectification of radio waves in 1902 while experimenting with a coherer detector consisting of a steel needle resting across two carbon blocks. On 29 May 1902 he was operating this device, listening to a radiotelegraphy station. Coherers required an external current source to operate, so he had the coherer and telephone earphone connected in series with a 3 cell battery to provide power to operate the earphone. Annoyed by background "frying" noise caused by the current through the carbon, he reached over to cut two of the battery cells out of the circuit to reduce the current The generation of an audio signal without a DC bias battery made Pickard realize the device was acting as a rectifier.

One the collections notable recordings was a brown Wax Cylinder (c.1895) from Wheeling, WV. This recording by the vocalist Edward M. Favor is one of the earliest recordings in the archives. Its volume is faint and was intended to be used with a tube and earphone type machine. Historians assume that not more than 50 pieces were made of this cylinder.

The 1S5 vacuum tube converted the radio signal to audio and the 3V4 amplified the audio for the headphone. The 1S5 tube functioned as a regenerative detector. Audio detected by the 1S5 was resistance-coupled to the 3V4, where it was amplified and supplied to the earphone. The detector was provided with a cathode feedback level well into the oscillation range by the 330 pF capacitor.

Ashley overhears and spins around to talk to him. He acts unflappable and doesn't falter as Britney gives him instructions through a hidden earphone. When Ashley seems impressed by his new look and attitude, Britney is overjoyed but causes Mike to crash into a clothing rack on his way out of the store because she squeals into her microphone. Britney then learns that Rick is dating Ashley.

This was applied to the rectifying detector with the radio carrier. In the detector the two signals mixed, creating a heterodyne (beat) signal at the difference fC - fC between these frequencies, which was in the audio frequency range. The heterodyne provided the audible tone in the earphone whenever the carrier was present. After vacuum tube oscillators were invented in 1913 by Alexander Meissner the heterodyne receiver replaced the tikker.

The earphone is on left. The antenna wire, right, has a clip to attach to metal objects such as a bedspring, which serve as an additional antenna to improve reception. A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio. It uses only the power of the received radio signal to produce sound, needing no external power.

Since this circuit lacked any frequency-selective elements besides the broad resonance of the antenna, it had little ability to reject unwanted stations, so all stations within a wide band of frequencies were heard in the earphone (in practice the most powerful usually drowns out the others). It was used in the earliest days of radio, when only one or two stations were within a crystal set's limited range.

In 2013, researchers of Tsinghua University further present a thermoacoustic earphone of carbon nanotube thin yarn and a thermoacoustic surface-mounted device.

Children's Literature praised Esperanza Rising and suggested that it "would be a great choice for a multicultural collection". The book has been incorporated into school curriculum in literature, social studies, and Spanish. The University of Missouri has a detailed literature unit available online, including maps, photos and links to other resources. Berkeley High School used recordings of the book with its English as a Second Language students in an Earphone English group.

The radio hat had an external battery pack that provided 1.5 volts for the filaments and the 22.5 volt B+ supply. These were much safer voltages for use in a hat, especially since the full plate voltage is dropped across the earphone. This technique was commonly used in many simple radios, some having ninety or more volts present across the head or earphones. The battery pack would power the radio for up to 20 hours.

Cliff Jumping: The producers thought all the men would jump at 40 feet, and all the women would jump at 20 feet. But they were shocked when Karrie and Mel jumped at 40 feet. So Tanya, who jumped at 20 feet, looked suspicious. Cliff Climbing: The producer secretly talked to Tanya by using a microphone while Tanya listen on her earphone and CD player (everyone thought she was listening to her favorite CD).

He proposed the novel concept that cartilage has a unique characteristic capable of transmitting sound. Because sound transmission via pathways that use air or bone are respectively called air conduction and bone conduction, the new pathway is referred to as cartilage conduction. This unique pathway has attracted the attention of several researchers and companies such that some hearing aid prototypes using cartilage conduction have been tested for use in smartphone and earphone.

A control on top of the unit allowed the tape speed to be varied between Slow (low quality/long recording time) and Fast (better quality/short recording time). The unit featured an input jack for a microphone, an output jack for an earphone and an internal speaker. The VU meter for monitoring the audio level on recording was used as also used in playback mode as a charge level indicator of the four AA batteries.

He created roles in the off-Broadway productions of Paul Rudnick's Jeffrey and Christopher Durang's Why Torture Is Wrong...And The People Who Love Them. He provided narration for the audiobook version of the Cormac McCarthy’s novels Blood Meridian and The Crossing. He won the 2004 Audie Award for his narration of East Of Eden, has been nominated three other times, and has been a frequent recipient of Audiofile Magazine's Earphone Award.

The distribution to subscribers was regulated by another patented device. Vacuum- tube amplification would not be developed until the 1910s, so there were limited means for producing signals strong enough to be heard throughout the system. Therefore, for transmitting the news, announcers with especially loud voices — known as stentors — were hired and instructed to speak as forcefully as possible into specially designed double-receivers. Home installations normally consisted of two earphone telephone receivers, connected to long, flexible wires.

This is equivalent to peak detection with a suitably long time constant. The amplitude of the recovered audio frequency varies with the modulating audio signal, so it can drive an earphone or an audio amplifier. Fessendon invented the first AM demodulator in 1904 called the electrolytic detector, consisting of a short needle dipping into a cup of dilute acid. The same year John Ambrose Fleming invented the Fleming valve or thermionic diode which could also rectify an AM signal.

For the 2009 model year, all Rio and Rio5 trims received standard Sirius Satellite Radio (complimentary for three months) and radios with USB port & auxiliary jack, the auxiliary jack substituting for a Bluetooth mobile phone connection for devices with an earphone jack, e.g., the iPhone.

At the same time, a Minister's chair and an acousticon earphone installation were also gifted. A second phase of reconstruction was planned which was to include a new chancel, vestries and session house. However, it was not until 1967 that the alterations to the chancel and other improvements, including the addition of a choir room and session house, were undertaken to the same architect's plans. The current church has several stained glass windows that were installed as memorials.

This starts a chain reaction which leads to the overturning of the status quo. An important character in the story is the President of the United States. A former New Jersey accountant, state senator and Governor, who nonetheless thinks of himself as a "hard riding, hard drinking Southern gentleman", he is a front for an army of advisers and fixers who tell him what to say through a wireless earphone. He leads the "Middle Roaders", apparently a Republican faction.

Muzik's headphones are wireless and are controlled by four touch-sensitive buttons on the outside of the right earphone, which allow the user to switch between songs, control volume, and share music with friends via social media networks such as Twitter, Facebook, and Spotify. Other features include high-definition audio, voice command, and motion sensor technology. The headphones also interface with Muzik Connect, a mobile app for Android and iOS that enables the product's social capabilities.

He shows abnormal regenerative abilities (being able to completely regenerate his forearm) and wears earphone-like machines which can release endorphins to dull his sense of pain. He often uses guns with abnormally powerful firepower. As a punishment for "losing Tetora" as well as several other blunders, he was disfigured. ;Kazuhiko Amamiya The real first appears in chapter 10 in a flashback of "20 years ago" where he is apparently killed and burnt by Nishizono Shinji and Murata Kiyoshi.

Old undamped moving iron speakers have a characteristic sound, with probably the worst sound quality of any type of speaker usable for speech. Modern damped moving iron mechanisms can provide respectable sound quality, and are used in headphones. The first moving iron transducer, the telephone receiver or earphone, evolved with the first telephone systems in the 1870s. Moving iron horn loudspeakers developed from earphones after the first amplifying device which could drive a speaker, the triode vacuum tube, was perfected around 1913.

He designed the world's first wearable electronic hearing aid: the microphone went on the lapel, the amplifier went in the jacket pocket and the earphone was small enough not to need a headband. Eventually, as technology improved, Stevens created a hearing aid that was small enough to fit completely in the outer ear. His hearing aids were used by Winston Churchill (who was Stevens's personal client), amongst others. He also designed audiometers and acoustic equipment such as protective communication headsets and helmets.

A subscriber could listen using both earphones, or, alternately, two persons could listen by each using a single earphone. A loud buzzer, strong enough to be heard throughout a room even when the subscriber's receivers were not currently being listened to, was used to draw attention to important announcements. The American author Thomas Denison, who visited Budapest in 1901, found that transmission of spoken news was "highly satisfactory", but the audio quality for musical programmes, whether vocal or instrumental, "still leaves something to be desired".

It functioned as a crude modulator; it interrupted the signal from the detector at an audio rate, producing a buzz in the earphone whenever the carrier was present. Thus the "dots" and "dashes" of the Morse code were made audible. Around 1915 the tikker was replaced by a better means of accomplishing the same thing; the "heterodyne receiver" invented by Reginald Fessenden in 1902. In this an electronic oscillator generated a radio signal at a frequency fo offset from the incoming radio wave carrier fC.

She sees Sugar not moving on the sofa, with her eyes closed, and thinks she has taken the pills and lost consciousness. She runs towards Sugar, and places her hands on her breasts, asking her to breathe. Sugar then exhales cigarette smoke in Kim's face and removes an earphone from her ear, wondering why Kim's hands are on her breasts. A thud is then heard in the corridor, and as Nathan and Stella come through the front door, they find Matt unconscious on the floor.

In the detector the two signals mixed, creating two new heterodyne (beat) frequencies at the sum fC + fO and the difference fC − fO between these frequencies. By choosing fO correctly the lower heterodyne fC − fO was in the audio frequency range, so it was audible as a tone in the earphone whenever the carrier was present. Thus the "dots" and "dashes" of Morse code were audible as musical "beeps". A major attraction of this method during this pre-amplification period was that the heterodyne receiver actually amplified the signal somewhat, the detector had "mixer gain".

When the earphone positions are reversed, the higher tones continue to appear to be coming from the right and the lower tones from the left. Other people experience different illusions, such as the higher tones on the left and the lower tones on the right, or a pattern in which the sounds appear to be localized in different and changing ways. Right- handers and left-handers differ statistically in how the scale illusion is perceived. In a clinical study, patients with hemispatial neglect were shown to experience the scale illusion.

In contrast the new continuous wave transmitters produced a signal consisting of pulses of continuous waves, unmodulated sinusoidal carrier waves, which were inaudible in the earphones.K. G. Beauchamp,History of telegraphy, IET, 2001 , page 201 So to receive this new modulation method, the receiver had to produce a tone during the pulses of carrier. The "tikker", invented in 1908 by Valdemar Poulsen, was the first primitive device that did this. It consisted of a vibrating switch contact between the receiver's detector and earphone, which was repeatedly opened by an electromagnet.

The sounds were weak and could only be heard when the ear was close to the earphone/mouthpiece, but they were distinct. In the third of his tests in Southern Ontario, on August 10, 1876, Bell made a call via the telegraph line from the family homestead in Brantford, Ontario, to his assistant located in Paris, Ontario, some 13 kilometers away. This test was claimed by many sources as the world's first long-distance call. The final test certainly proved that the telephone could work over long distances.

Denby has published poetry collections and novels. She continues to perform regularly at live venues and appears on television and radio. She has also recorded a number of unabridged audiobooks, including two recordings of her own novels (one of which, Stone Baby, won the US Audio Industry 'Earphone Award'). Denby also managed the band 'New York Alcoholic Anxiety Attack' and latterly works with 'Utopian Love Revival' with whom she also has a side- project, 'Death By Rock 'N' Roll' featuring live performances of her poetry set to rock music written for her by the band.

Also, the impedance of the tuner that supplies the radio signal must be low to match the low impedance of the excitation coil, requiring special tuner design considerations. The impedance of the telephone earphone must roughly match the impedance of the audio pickup coil, which is a few hundred ohms. The iron band moves a few millimeters per second. The magnetic detector was much more sensitive than the coherers commonly in use at the time, although not as sensitive as the Fleming valve, which began to replace it around 1912.

On September 18, 2019, Maroon 5 announced the release of the song with its cover art on social media after posting several collages of photos. The song's cover art was created by Mexican artist, Andreas Hijar (also known as Golgo). On September 25, the band collaborated with Apple for a feature within the Photos app to promote the track, allowing users to make a montage of their photos set to the song. An advertisement was used with the Dillion Francis remix version appeared on the Shure wireless earphone Aonic 215 and the headphone Aonic 50.

A common short form of the term is phone, which came into use almost immediately after the first patent was issued. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a microphone (transmitter) to speak into and an earphone (receiver) which reproduces the voice in a distant location.

An example of a full-duplex device is plain old telephone service; the parties at both ends of a call can speak and be heard by the other party simultaneously. The earphone reproduces the speech of the remote party as the microphone transmits the speech of the local party. There is a two-way communication channel between them, or more strictly speaking because there are two communication channels between them. In a half-duplex or semiduplex system, both parties can communicate with each other, but not simultaneously; the communication is one direction at a time.

Global Revenue from Smart Wearables and hearables Most systems in development are designed for binaural use and share a basic set of desired functionalities. Currently the deployment of hearables is on the agenda of many consumer technology manufacturers. The first hearable product to enter the marketplace was the iriverON Bluetooth headset, launched in late 2013, which integrated biometric sensor technology into a Bluetooth audio headset. Other biometric have since followed in the market, including the Jabra Sport Pulse, the Sony B-Trainer, the LG HR Earphone, and other biometric Bluetooth headsets.

AM radio technology is simpler than later transmission systems. An AM receiver detects amplitude variations in the radio waves at a particular frequency, then amplifies changes in the signal voltage to operate a loudspeaker or earphone. However, the simplicity of AM transmission also makes it vulnerable to "static" (radio noise, radio frequency interference) created by both natural atmospheric electrical activity such as lightning, and electrical and electronic equipment, including fluorescent lights, motors and vehicle ignition systems. In large urban centres, AM radio signals can be severely disrupted by metal structures and tall buildings.

The most familiar form of radio receiver is a broadcast receiver, often just called a radio, which receives audio programs intended for public reception transmitted by local radio stations. The sound is reproduced either by a loudspeaker in the radio or an earphone which plugs into a jack on the radio. The radio requires electric power, provided either by batteries inside the radio or a power cord which plugs into an electric outlet. All radios have a volume control to adjust the loudness of the audio, and some type of "tuning" control to select the radio station to be received.

The diver's speech is picked up by the microphone and converted into a high frequency sound signal transmitted to the water by the omnidirectional transducer. The signal can bounce off the bottom and surface and other obstructions, which can extend the range around obstructions, but will also degrade the signal due to interference effects caused by varying path lengths of different routes. When a receiving transducer picks up the signal, the ultrasonic signal is converted to an amplitude modulated electrical signal, amplified and converted to sound by the earphone. The through-water communications sets carried by the divers are battery powered.

At the output of the amplifier the audio is separated from the RF signal by the low pass filter and is applied to the earphone. The amplifier could be a single stage or multiple stages. It can be seen that since each active device (tube or transistor) is used to amplify the signal twice, the reflex circuit is equivalent to an ordinary receiver with double the number of active devices. The reflex receiver should not be confused with a regenerative receiver, in which the same signal is fed back from the output of the amplifier to its input.

The 3rd-generation iPod Shuffle does not have any controls on the actual player; instead, it has a small control on the earphone cable, with volume-up and -down buttons and a single button for play and pause, next track, etc. The iPod Touch has no click-wheel; instead, it uses a touch screen along with a home button, sleep/wake button, and (on the second and third generations of the iPod Touch) volume-up and -down buttons. The user interface for the iPod Touch is identical to that of the iPhone. Differences include the lack of a phone application.

The train is equipped with modern technology such CCTV and smoke detector. Seats have sleep and reading lights, audio jack for earphone or headset, fold-able mini tables on the armrests, and separate cabin baggage. Additionally Argo Parahyangan that departs from Gambir at 08.45 WIB and 18.45 WIB, and from Bandung at 05.00 WIB and 14.15 WIB, has one Priority class coach with seating capacity of 28 passengers. This train car has extra facilities such as audio video on demand (AVOD) in every seat, a minibar, 52-inch flat screen TV, special attendants, luxurious toilet, as well as premium seats.

The detector produced electronic noise that was heard in the earphone as a "hissing" or "roaring" sound in the background, somewhat fatiguing to listen to. Phillips (1980) Early radio wave detectors, p. 98, 102, 106 This was Barkhausen noise due to the Barkhausen effect in the iron. As the magnetic field in a given area of the iron wire changed as it moved through the detector, the microscopic domain walls between magnetic domains in the iron moved in a series of jerks, as they got hung up on defects in the iron crystal lattice, then pulled free.

From 2003 to 2006 Slyusarchuk lived in a Lviv Polytechnic National University dormitory, where he fraudulently diagnosed students and "treated" them with psychotropic drugs. He extorted large amounts of money from parents for treatment, telling them that their children would commit suicide without it, and distributed unapproved drugs for $4,000 per ampoule. On 28 February 2006, Slyusarchuk claimed to have set a record by memorizing the numbers which make up pi. Journalists from Ekspres and Moskovskij Komsomolets noted that at his public performances, he was attended by a nearby assistant with a computer (and, perhaps, a small earphone).

Valendora is disgusted when his boss at the lab decides that certain harmful side-effects of the product, Aztec Cocawine, can be overlooked. At this point an air-raid drill throws everything into confusion. Denzer and Maggie have to spend time in the shelter where everyone around them wants to discuss, as loudly as possible, the upcoming All-Star Game or the C.S.B. Frustrated beyond measure, Maggie yells at those near her to shut up, uttering the rude "P-word" (politics), much to Denzer's dismay. President Braden appears at the daily White House press briefing, where it becomes apparent that he simply parrots what he hears in his earphone.

Usually the device gives some indication of distance; the closer the metal is, the higher the tone in the earphone or the higher the needle goes. Another common type are stationary "walk through" metal detectors used for security screening at access points in prisons, courthouses, and airports to detect concealed metal weapons on a person's body. The main types of metal detectors are, beat-frequency oscillation, very low frequency, pulse induction and industrial. 3 Main Kinds of Metal Detectors The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field.

This diagram shows a simplified explanation of how it works: :(A) This graph shows the amplitude modulated radio signal from the receiver's tuned circuit, which is applied as a voltage across the detector's contacts. The rapid oscillations are the radio frequency carrier wave. The audio signal (the sound) is contained in the slow variations (modulation) of the size of the waves. If this signal were applied directly to the earphone, it could not be converted to sound, because the audio excursions are the same on both sides of the axis, averaging out to zero, which would result in no net motion of the earphone's diaphragm.

Tying the Butterfly coil, 1-folding or faking-down Tying the Butterfly coil, 2-wrapping Tying the Butterfly coil, 3-finished The butterfly coil (also known as a backpacker's coil) is a method used by climbers for storing and transporting a climbing rope. Slinging the coiled rope over the shoulders and tying it in place for carrying earns the technique its alternative name. Unlike the alpine coil it cannot be attached to a harness for climbing, and thus is useful only for transporting a rope to and from where it must be used. The method is also useful for much smaller items such as for keeping earphone cables from tangling.

The 3.5 mm or miniature size was originally designed in the 1950s as two-conductor connectors for earpieces on transistor radios, and remains a standard still used today. This roughly half-sized version of the original, popularized by the Sony EFM-117J radio (released in 1964),Description of 3.5 mm earphone jack in described model: is still commonly used in portable applications. The three-conductor version became very popular with its application on the Walkman in 1979, as unlike earlier transistor radios, these devices had no speaker of their own; the usual way to listen to them was to plug in headphones. There is also an EIA standard for 0.141-inch miniature phone jacks.

Comes in a large tin case (Diameter: 28 cm approx.). First Press Comes with Poster.

Tanya's Briefings: In season one, the Mole (David Buxton) would have late-night meetings with the producers about the challenges. This season, the producer would use and talk to Tanya via earphone to tell her about the challenges. He would then request Tanya to give him a sign (such as flicking her hotel room lights on and off twice) to confirm that she got his message. Bomb Defusing: Tanya blew the bomb up by turning the knob on the control panel the wrong way (unknown to the other players), but the bomb blew up more quickly than she thought, so the look on her face when the explosion happened was for real.

Another method involved sinking a water-filled oil drum into the floor of the trench, with lookout soldiers taking turns to lower an ear into the water to listen for vibrations. Improvised methods later included Water Board inspector short-sticks, each with a single vibrating wire-type earphone attached, or using filled French water-bottles laid flat on their sides in pairs, so they could be listened-to through medical stethoscopes. Underground, within the tunnelling operations, side-shaft listening posts were deployed and manned by soldiers whose job entailed listening for indications that the enemy was tunnelling. Initially using just manual methods, the British were eventually equipped with the Geophone, which could detect noises up to away.

Fessenden, more than any other person, is responsible for developing amplitude modulation (AM) radio transmission around 1900. While working to develop AM transmitters, he realized that the radio wave detectors used in existing radio receivers were not suitable to receive AM signals. The radio transmitters of the time transmitted information by radiotelegraphy; the transmitter was turned on and off by the operator using a switch called a telegraph key producing pulses of radio waves, to transmit text data using Morse code. Thus receivers didn't have to extract an audio signal from the radio signal, but only detected the presence or absence of the radio frequency to produce "clicks" in the earphone representing the pulses of Morse code.

To receive this new modulation type, the receiver had to produce some kind of tone during the pulses of carrier. The first crude device that did this was the tikker, invented in 1908 by Valdemar Poulsen. This was a vibrating interrupter with a capacitor at the tuner output which served as a rudimentary modulator, interrupting the carrier at an audio rate, thus producing a buzz in the earphone when the carrier was present. Lee, Thomas H. (2004) The Design of CMOS Radio Frequency Integrated Circuits, 2nd Ed., p. 14-15 A similar device was the "tone wheel" invented by Rudolph Goldschmidt, a wheel spun by a motor with contacts spaced around its circumference, which made contact with a stationary brush.

At the receiver, the oscillating electric and magnetic fields of the incoming radio wave push the electrons in the receiving antenna back and forth, creating a tiny oscillating voltage which is a weaker replica of the current in the transmitting antenna. This voltage is applied to the radio receiver, which extracts the information signal. The receiver first uses a bandpass filter to separate the desired radio station's radio signal from all the other radio signals picked up by the antenna, then amplifies the signal so it is stronger, then finally extracts the information-bearing modulation signal in a demodulator. The recovered signal is sent to a loudspeaker or earphone to produce sound, or a television display screen to produce a visible image, or other devices.

Inductively-coupled circuit with impedance matching. This type was used in most quality crystal receivers in the early 20th century Amateur-built crystal receiver with "loose coupler" antenna transformer, Belfast, around 1914 In more sophisticated crystal receivers, the tuning coil is replaced with an adjustable air core antenna coupling transformer which improves the selectivity by a technique called loose coupling. This consists of two magnetically coupled coils of wire, one (the primary) attached to the antenna and ground and the other (the secondary) attached to the rest of the circuit. The current from the antenna creates an alternating magnetic field in the primary coil, which induced a current in the secondary coil which was then rectified and powered the earphone.

The device that did this was called a "detector". The detector used in receivers of that day, called a coherer, simply acted as a switch, that conducted current in the presence of radio waves, and thus did not have the capability to demodulate, or extract the audio signal from, an amplitude modulated radio wave. The simplest way to extract the sound waveform from an AM signal is to rectify it; remove the oscillations on one side of the wave, converting it from an alternating current to a varying direct current. The variations in the amplitude of the radio wave that represent the sound waveform will cause variations in the current, and thus can be converted to sound by an earphone.

The SL line had the mic/earphone ports, volume knob and reset button on a small satellite board. A jumper on the board allowed the user to change the microphone input to a line-level output. The SL series offered five 8-bit XT-compatible ISA slots, and did not come with pre- installed real-time clock chips, making them optional upgrades in the form of the plug-in Dallas DS1216E SmartWatch. The SL is the only machine in the line that offers an upper 5.25" bay, and therefore the only model to offer two 5.25" bays, where the other models, including the SL/2 and the entire TL range, feature two upper 3.5" bays and one lower 5.25" bay.

Unlike other microphone types, the carbon microphone can also be used as a type of amplifier, using a small amount of sound energy to control a larger amount of electrical energy. Carbon microphones found use as early telephone repeaters, making long-distance phone calls possible in the era before vacuum tubes. Called a Brown's relay, these repeaters worked by mechanically coupling a magnetic telephone receiver to a carbon microphone: the faint signal from the receiver was transferred to the microphone, where it modulated a stronger electric current, producing a stronger electrical signal to send down the line. One illustration of this amplifier effect was the oscillation caused by feedback, resulting in an audible squeal from the old "candlestick" telephone if its earphone was placed near the carbon microphone.

1087892, Wilhelm Schloemilch and Otto von Bronk Means for receiving electrical oscillations, filed March 14, 1913; granted February 17, 1914 and rediscovered and extended to multiple tubes in 1917 by Marius LatourUS Patent no. 1405523, Marius Latour Audion or lamp relay or amplifying apparatus, filed December 28, 1917; granted February 7, 1922 and William H. Priess. The radio signal from the antenna and tuned circuit passes through an amplifier, is demodulated in a detector which extracts the audio signal from the radio carrier, and the resulting audio signal passes again through the same amplifier for audio amplification before being applied to the earphone or loudspeaker. The reason for using the amplifier for "double duty" was to reduce the number of active devices, vacuum tubes or transistors, required in the circuit, to reduce the cost.

Morris has narrated a number of audiobooks, a few of which have earned her AudioFile magazine's Earphones Awards, the first was for the young adult novel Dear Zoe by Philip Beard in 2004. Other Earphone Award-winning titles include Salt to the Sea by Ruta Sepetys, Pip Bartlett's Guide to Magical Creatures by Jackson Pearce, and The Tapper Twins Go To War (With Each Other) by Geoff Rodkey. The audiobook The Elegance of the Hedgehog by Muriel Barbery, where Morris voiced the 12-year-old Paloma, won AudioFile's Best Audiobook of the Year and Publishers Weekly Listen Up Award. Her narration of children's book A Snicker of Magic by Natalie Lloyd received a nomination at the 2015 Audie Awards and received the Honor Recording Odyssey Award from the American Library Association.

Although all of these are problematic in application, due to the widespread use and economic importance of wireless telecommunication systems in modern civilization, there is an increased popularity of such measures in the general public, though also evidence that such approaches may increase concern. They involve recommendations such as the minimization of usage, the limitation of use by at-risk population (e.g., children), the adoption of phones and microcells with as low as reasonably practicable levels of radiation, the wider use of hands-free and earphone technologies such as Bluetooth headsets, the adoption of maximal standards of exposure, RF field intensity and distance of base stations antennas from human habitations, and so forth. Overall, public information remains a challenge as various health consequences are evoked in the literature and by the media, putting populations under chronic exposure to potentially worrying information.

An important principle used in crystal radio design to transfer maximum power to the earphone is impedance matching. The maximum power is transferred from one part of a circuit to another when the impedance of one circuit is the complex conjugate of that of the other; this implies that the two circuits should have equal resistance. However, in crystal sets, the impedance of the antenna-ground system (around 10-200 ohms) is usually lower than the impedance of the receiver's tuned circuit (thousands of ohms at resonance), and also varies depending on the quality of the ground attachment, length of the antenna, and the frequency to which the receiver is tuned. Therefore, in improved receiver circuits, in order to match the antenna impedance to the receiver's impedance, the antenna was connected across only a portion of the tuning coil's turns.

Block diagram of a tuned radio frequency receiver. To achieve enough selectivity to reject stations on adjacent frequencies, multiple cascaded bandpass filter stages had to be used. The dotted line indicates that the bandpass filters must be tuned together. In the simplest type of radio receiver, called a tuned radio frequency (TRF) receiver, the three functions above are performed consecutively: Chapter 1 (1) the mix of radio signals from the antenna is filtered to extract the signal of the desired transmitter; (2) this oscillating voltage is sent through a radio frequency (RF) amplifier to increase its strength to a level sufficient to drive the demodulator; (3) the demodulator recovers the modulation signal (which in broadcast receivers is an audio signal, a voltage oscillating at an audio frequency rate representing the sound waves) from the modulated radio carrier wave; (4) the modulation signal is amplified further in an audio amplifier, then is applied to a loudspeaker or earphone to convert it to sound waves.

Domains change size by the domain walls moving within the crystal lattice in response to changes in the magnetic field, by the process of dipoles near the wall changing spin to align with spins in the neighboring domain. In a perfect crystal lattice this is can be a continuous process, but in actual crystals local defects in the lattice, such as impurity atoms or dislocations in the structure form temporary barriers to the change of spin, causing the domain wall to be hung up on the defect. When the change in magnetic field becomes strong enough to overcome the local energy barrier at the defect, it causes a group of atoms to flip their spin at once, as the domain wall "snaps" past the defect. This sudden change in magnetization causes a transient change in magnetic flux through the bar, which is picked up by the coil as a "click" in the earphone.

108 During the first three decades of radio, from 1888 to 1918, called the wireless telegraphy or "spark" era, primitive radio transmitters called spark gap transmitters were used, which generated radio waves by an electric spark. These transmitters were unable to produce the continuous sinusoidal waves which are used to transmit audio (sound) in modern AM or FM radio transmission. Instead spark gap transmitters transmitted information by wireless telegraphy; the user turned the transmitter on and off rapidly by tapping on a telegraph key, producing pulses of radio waves which spelled out text messages in Morse code. Therefore, the radio receivers of this era did not have to demodulate the radio wave, extract an audio signal from it as modern receivers do, they merely had to detect the presence or absence of the radio waves, to make a sound in the earphone when the radio wave was present to represent the "dots" and "dashes" of Morse code.

The wing, which fell on the airfield, was torn off, almost killing the officer, who at the last moment had been dragged off by other officers. As the mechanics who observed the flight from the sites, the explosion occurred after several sharp dives into the lane: with a sharp exit from the next dive, the plane sharply jerked and disappeared into the fire cloud of the explosion, from which turbines and large fragments flew. The airfield directly under the crash site, where I ran out of the barracks of the 2nd regiment, was littered with a layer of small smoking debris. In the distance, there were several larger fragments in various places. In the middle of the strip, I remember the flight white helmet, and under it on the concrete – a scattering of blue plastic fragments of light-protective cover and inscription around the Nadtochiev earphone ... 30 September 1991 and the plane crashed MiG-31B under the command of Major Shapovalov S. A. and Pilot- Navigator Lieutenant Colonel M. V. Subbotin, performing a training flight before upcoming display of aviation technology.

Amateur radio operator transmitting Morse code Wireless telegraphy or radiotelegraphy, commonly called CW (continuous wave), ICW (interrupted continuous wave) transmission, or on-off keying, and designated by the International Telecommunication Union as emission type A1A, is a radio communication method in which the sending operator manipulates a switch called a telegraph key, which turns the radio transmitter on and off, producing pulses of unmodulated carrier wave of different lengths called "dots" and "dashes", which encode characters of text, usually in Morse code. At the receiving location, the code is audible in the radio receiver's earphone or speaker as a sequence of buzzes or beeps, which is translated back to text by an operator who knows Morse code. Although this type of communication has been mostly replaced since its introduction over 100 years ago by other means of communication it is still used by amateur radio operators as well as some military services.Morse code training in the Air Force A CW coastal station, KSM, still exists in California, run primarily as a museum by volunteers,Coast Station KSM and occasional contacts with ships are made.
