Michell antique phonograph
The phonograph is a tool developed in 1877 for the mechanical tracking and reproduction 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 recorded as equivalent physical deviations of the spiral groove etched, etched, incised, or impressed into the surface of the revolving disk or cylinder, called a "record". To recreate the audio, the surface is in the same way rotated while a playback stylus traces the groove which is therefore vibrated by it, very faintly reproducing the noted sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air by having a flaring horn, or right to the listener's ears through stethoscope-type earphones. In later electric phonographs (also called record players (since 1940s) or, most recently, turntables), the motions of the stylus are converted into an analogous electric signal by a transducer, modified back into audio with a loudspeaker then.
The phonograph was invented in 1877 by Thomas Edison. While other inventors experienced produced devices that can record noises, Edison's phonograph was the first to have the ability to reproduce the noted audio. His phonograph actually recorded sound onto a tinfoil sheet twisted around a revolving cylinder. A stylus giving an answer to appear 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.
In the 1890s, Emile Berliner initiated the changeover from phonograph cylinders to chiseled discs with a spiral groove working from the periphery to close to the center. Later advancements over time included improvements to the turntable and its drive system, the needle or stylus, and the sound and equalization systems.
The disc phonograph record was the prominent audio recording format throughout almost all of the 20th century. Through the mid-1980s on, phonograph use on a standard record player declined sharply because of the rise of the cassette tape, compact disk and other digital saving formats. Details are a popular format for some audiophiles and DJs still. Vinyl records are still used by some DJs and musicians in their concert performances. Musicians continue steadily to release their recordings on vinyl records. The original recordings of musicians are occasionally re-issued on vinyl fabric.
Usage of terminology is not uniform over the English-speaking world (see below). In newer 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 derived from the Greek words ???? (phon?, "sound" or "voice") and ????? (graph?, "writing"). The similar related conditions gramophone (from the Greek ?????? gramma "letter" and ???? ph?n? "tone of voice") and graphophone have similar main meanings. The roots were already familiar from existing 19th-century words such as picture ("light writing"), telegraph ("distant writing"), and cell phone ("distant sound"). The new term may 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 ad for "Professor Webster's phonographic class", and in 1859 the brand new York State Professors Association tabled a motion to "hire a phonographic recorder" to track record its meetings.
Arguably, any device used to track record sound or reproduce noted sound could be called a type of "phonograph", however in common practice the term has come to signify traditional solutions of sensible taking, regarding audio-frequency modulations of a physical track or groove.
In the past due 19th and early 20th generations, "Phonograph", "Gramophone", "Graphophone", "Zonophone" and the like were still brands specific to various creators of sometimes completely different (i.e. cylinder and disc) machines; so substantial use was made of the universal term "talking machine", especially in print. "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 lip area - a potential source of misunderstandings both and today then.
In British British, "gramophone" may make reference to any sound-reproducing machine using disc records, that have been popularized and launched in the UK 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, but in 1910 an English court decision decreed it had turn into a generic term; it has been so used in the UK and most Commonwealth countries ever since. The word "phonograph" was usually restricted to machines which used cylinder records.
"Gramophone" generally referred to a wind-up machine. Following the introduction of the softer vinyl information, 33 1/3-rpm LPs (long-playing details) and 45-rpm "single" or two-song details, and EPs (extended-play recordings), the normal name became "record player" or "turntable". Usually 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 term; "turntable" was a far more technical term; "gramophone" was limited to the old mechanised (i.e., wind-up) players; and "phonograph" was used as in British English.
