The phonograph is a device created in 1877 for the mechanical recording and duplication of audio. In its later forms it is also called a gramophone (as a trademark since 1887, as a generic name since c. 1900). The audio vibration waveforms are saved as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of any spinning disc or cylinder, called a "record". To recreate the sound, the top is likewise rotated while a playback stylus traces the groove and is therefore vibrated because of it, very reproducing the saved audio faintly. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through the flaring horn, or directly to the listener's ears through stethoscope-type earphones. In later electric phonographs (also known as record players (since 1940s) or, most recently, turntables), the movements of the stylus are converted into an analogous electrical power signal by the transducer, changed back into audio by the loudspeaker then.
The phonograph was developed in 1877 by Thomas Edison. While other inventors possessed produced devices that could record tones, Edison's phonograph was the first ever to have the ability to reproduce the registered sound. His phonograph originally recorded audio onto a tinfoil sheet covered around a spinning cylinder. A stylus giving an answer to sound vibrations produced an and down or hill-and-dale groove in the foil up. Alexander Graham Bell's Volta Laboratory made several improvements in the 1880s, including the use of wax-coated cardboard cylinders, and a cutting stylus that moved from side to side in a "zig zag" groove across the record.
Inside the 1890s, Emile Berliner initiated the change from phonograph cylinders to chiseled discs with a spiral groove jogging from the periphery to near the center. Later advancements over time included alterations to the turntable and its drive system, the needle or stylus, and the equalization and audio systems.
The disc phonograph record was the dominating audio recording format throughout the majority of the 20th hundred years. In the mid-1980s on, phonograph use on a standard record player declined as a result of rise of the cassette tape sharply, compact disk and other digital tracking formats. Files are a popular format for some audiophiles and DJs still. Vinyl records are used by some DJs and musicians in their concert performances still. Musicians continue to release their recordings on vinyl records. The initial recordings of music artists are re-issued on vinyl sometimes.
Usage of terminology is not uniform over the English-speaking world (see below). In newer usage, the playback device is often called a "turntable", "record player", or "record changer". When used in conjunction with a mixing machine as part of a DJ setup, turntables are often called "decks".
The term phonograph ("sound writing") was produced from the Greek words ???? (phon?, "sound" or "voice") and ????? (graph?, "writing"). The similar related terms gramophone (from the Greek ?????? gramma "letter" and ???? ph?n? "voice") and graphophone have similar main meanings. The root base were already familiar from existing 19th-century words such as photo ("light writing"), telegraph ("distant writing"), and cell phone ("distant sound"). The brand new term might have been inspired by the existing words phonographic and phonography, which described a system of phonetic shorthand; in 1852 THE BRAND NEW York Times taken an advertising campaign for "Professor Webster's phonographic class", and in 1859 the brand new York State Instructors Association tabled a motion to "hire a phonographic recorder" to track record its meetings.
Arguably, any device used to track record audio or reproduce noted sound could be called a type of "phonograph", but in common practice the expressed term has come to mean traditional systems of audio documenting, regarding audio-frequency modulations of the physical groove or trace.
In the late 19th and early on 20th generations, "Phonograph", "Gramophone", "Graphophone", "Zonophone" and the like were still brand names specific to various creators of sometimes very different (i.e. cylinder and disk) machines; so significant use was manufactured from the universal term "talking machine", in print especially. "Talking machine" had earlier been used to make reference to complicated devices which produced a crude imitation of speech, by simulating the workings of the vocal cords, tongue, and mouth - a potential way to obtain misunderstanding both and now then.
In British British, "gramophone" may make reference to any sound-reproducing machine using disc records, that have been unveiled and popularized in the united kingdom by the Gramophone Company. Originally, "gramophone" was a proprietary trademark of this company and any use of the name by competing makers of disc records was vigorously prosecuted in the courts, however in 1910 an English court decision decreed so it had become a generic term; it has been so used in the UK & most Commonwealth countries ever since. The term "phonograph" was usually limited to machines which used cylinder records.
"Gramophone" generally described a wind-up machine. Following the intro of the softer vinyl details, 33 1/3-rpm LPs (long-playing documents) and 45-rpm "single" or two-song files, and EPs (extended-play recordings), the normal name became "record player" or "turntable". Often the home record player was part of something that included a radio (radiogram) and, later, may also play audiotape cassettes. From about 1960, such a system began to be described as a "hi-fi" (high-fidelity, monophonic) or a "stereo" (most systems being stereophonic by the mid-1960s).
In Australian English, "record player" was the word; "turntable" was a more technical term; "gramophone" was restricted to the old mechanised (i.e., wind-up) players; and "phonograph" was used such as British English.
