NAD Electronics antique phonograph

The phonograph is a device created in 1877 for the mechanical duplication and taking of audio. In its later forms additionally it is called a gramophone (as a trademark since 1887, as a generic name since c. 1900). The sound vibration waveforms are documented as related physical deviations of your spiral groove imprinted, etched, incised, or impressed into the surface of an spinning cylinder or disc, called a "record". To recreate the audio, the surface is similarly rotated while a playback stylus traces the groove and it is therefore vibrated by it, very reproducing the recorded sound faintly. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air by using 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, most recently, turntables), the motions of the stylus are changed into an analogous electric signal by way of a transducer, modified back into audio by the loudspeaker then.

The phonograph was invented in 1877 by Thomas Edison. While other inventors possessed produced devices which could record looks, Edison's phonograph was the first to be able to reproduce the noted audio. His phonograph actually recorded sound onto a tinfoil sheet covered around a revolving 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 about the record.

Within the 1890s, Emile Berliner initiated the transition from phonograph cylinders to level discs with a spiral groove operating from the periphery to near the center. Later improvements through the years included modifications to the turntable and its own drive system, the needle or stylus, and the equalization and sound systems.

The disc phonograph record was the dominating audio taking format throughout almost all of the 20th hundred years. From the mid-1980s on, phonograph use on a standard record player declined sharply due to rise of the cassette tape, compact disk and other digital recording formats. Information remain a popular format for some audiophiles and DJs. Vinyl records are being used by some DJs and musicians in their concert performances still. Musicians continue to release their recordings on vinyl records. The original recordings of musicians are re-issued on vinyl sometimes.

Usage of terminology is not even across the English-speaking world (see below). In more modern usage, the playback device is named a "turntable", "record player", or "record changer". When found in conjunction with a mixer as part of a DJ set up, 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 root meanings. The root base were already familiar from existing 19th-century words such as photo ("light writing"), telegraph ("distant writing"), and telephone ("distant sound"). The new term might have been inspired by the existing words phonographic and phonography, which described something of phonetic shorthand; in 1852 THE BRAND NEW York Times taken an advertising campaign for "Professor Webster's phonographic class", and in 1859 the New York State Professors Relationship tabled a motion to "employ a phonographic recorder" to track record its meetings.

Arguably, any device used to record sound or reproduce recorded audio could be called a type of "phonograph", however in common practice the term has come to signify historic technologies of sound taking, involving audio-frequency modulations of a physical groove or trace.

In the past due 19th and early 20th decades, "Phonograph", "Gramophone", "Graphophone", "Zonophone" and so on were still brand names specific to various creators of sometimes very different (i.e. cylinder and disc) machines; so appreciable use was manufactured from the common 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 lips - a potential source of confusion both then and today.

In British British, "gramophone" may refer to any sound-reproducing machine using disk records, that have been popularized and released in the united kingdom by the Gramophone Company. Originally, "gramophone" was a proprietary trademark of that 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 that it had turn into a generic term; it has been so used in the united kingdom & most Commonwealth countries since. The term "phonograph" was usually restricted to machines that used cylinder records.

"Gramophone" generally described a wind-up machine. Following the release of the softer vinyl fabric data, 33 1/3-rpm LPs (long-playing information) and 45-rpm "single" or two-song data, 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 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 complex term; "gramophone" was limited to the old mechanical (i.e., wind-up) players; and "phonograph" was used such as British English.
