The phonograph is a device developed in 1877 for the mechanised reproduction and recording of sound. In its later forms additionally it is called a gramophone (as a trademark since 1887, as a generic name since c. 1900). The audio vibration waveforms are recorded as equivalent physical deviations of the spiral groove engraved, etched, incised, or impressed into the surface of any spinning disk or cylinder, called a "record". To recreate the audio, the surface is likewise rotated while a playback stylus traces the groove which is therefore vibrated by it, very reproducing the documented sound faintly. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves that have been coupled to the open air by way of a 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, lately, turntables), the movements of the stylus are changed into an analogous electrical signal with a transducer, altered back to sound by way of a loudspeaker then.
The phonograph was created in 1877 by Thomas Edison. While other inventors had produced devices that can record looks, Edison's phonograph was the first to be able to reproduce the documented sound. His phonograph at first recorded sound onto a tinfoil sheet twisted around a spinning cylinder. A stylus responding 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 laterally in a "zig zag" groove round the record.
Within the 1890s, Emile Berliner initiated the transition from phonograph cylinders to smooth discs with a spiral groove jogging from the periphery to near the center. Later improvements over time included modifications to the turntable and its drive system, the needle or stylus, and the audio and equalization systems.
The disc phonograph record was the prominent audio saving format throughout the majority of the 20th century. In the mid-1980s on, phonograph use on a standard record player declined sharply as a result of rise of the cassette tape, compact disk and other digital tracking formats. Files are still a favorite format for a few audiophiles and DJs. Vinyl records are used by some DJs and musicians in their concert performances still. Musicians continue steadily to release their recordings on vinyl records. The initial recordings of musicians are re-issued on vinyl sometimes.
Using terminology is not standard 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 mixer as part of a DJ installation, turntables tend to be called "decks".
The term phonograph ("sound writing") was derived from the Greek words ???? (phon?, "sound" or "voice") and ????? (graph?, "writing"). The similar related terms gramophone (from the Greek ?????? gramma "notice" and ???? ph?n? "tone of voice") and graphophone have similar root 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 new term may have been inspired by the prevailing words phonographic and phonography, which referred to something of phonetic shorthand; in 1852 THE BRAND NEW York Times carried an ad for "Professor Webster's phonographic class", and in 1859 the New York State Teachers Connection tabled a action to "employ a phonographic recorder" to record its meetings.
Arguably, any device used to track record sound or reproduce saved audio could be called a type of "phonograph", but in common practice the term has come to signify traditional technology of acoustics recording, including audio-frequency modulations of the physical groove or trace.
In the past due 19th and early 20th decades, "Phonograph", "Gramophone", "Graphophone", "Zonophone" and so on were still brands specific to various manufacturers of sometimes very different (i.e. cylinder and disk) machines; so substantial use was made of the universal term "talking machine", in print especially. "Talking machine" had earlier been used to refer to complicated devices which produced a crude imitation of speech, by simulating the workings of the vocal cords, tongue, and lips - a potential source of confusion both and today then.
In British English, "gramophone" may make reference to any sound-reproducing machine using disk records, that have been presented 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, but in 1910 an English court decision decreed so it had turn into a generic term; it has been so used in the united kingdom & most Commonwealth countries ever since. The word "phonograph" was usually restricted to machines that used cylinder records.
"Gramophone" generally described a wind-up machine. After the benefits of the softer vinyl records, 33 1/3-rpm LPs (long-playing details) 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 a system that included a radio (radiogram) and, later, might play audiotape cassettes also. From about 1960, such something 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 far more technical term; "gramophone" was limited to the old mechanised (i.e., wind-up) players; and "phonograph" was used just as British English.
