NAD Electronics antique phonograph
The phonograph is a tool developed in 1877 for the mechanical tracking and duplication of sound. 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 imprinted, etched, incised, or impressed into the surface of your spinning cylinder or disc, called a "record". To recreate the audio, the top is likewise rotated while a playback stylus traces the groove which is therefore vibrated by it, very faintly reproducing the documented sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves that have been 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 called record players (since 1940s) or, lately, turntables), the motions of the stylus are changed into an analogous electric signal by the transducer, altered back to audio by way of a loudspeaker then.
The phonograph was invented in 1877 by Thomas Edison. While other inventors acquired produced devices that may record does sound, Edison's phonograph was the first ever to be able to reproduce the recorded sound. His phonograph actually recorded audio onto a tinfoil sheet twisted around a rotating cylinder. A stylus responding to reasonable vibrations produced an along or hill-and-dale groove in the foil. 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 surrounding the record.
In the 1890s, Emile Berliner initiated the move from phonograph cylinders to chiseled discs with a spiral groove working from the periphery to close to the center. Later improvements over time included alterations to the turntable and its own drive system, the stylus or needle, and the equalization and audio systems.
The disk phonograph record was the dominating audio taking format throughout most of the 20th hundred years. From the mid-1980s on, phonograph use on a standard record player declined because of the rise of the cassette tape sharply, compact disc and other digital saving formats. Information are still a popular format for a few 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 initial recordings of music artists are sometimes re-issued on vinyl fabric.
Using terminology is not even over 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 mixing machine within a DJ installation, 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 terms gramophone (from the Greek ?????? gramma "notice" and ???? ph?n? "words") and graphophone have similar main meanings. The origins were already familiar from existing 19th-century words such as photograph ("light writing"), telegraph ("distant writing"), and mobile phone ("distant sound"). The new term may have been influenced by the existing words phonographic and phonography, which described a system of phonetic shorthand; in 1852 The New York Times carried an advert for "Professor Webster's phonographic class", and in 1859 the brand new York State Instructors Relationship tabled a motion to "employ a phonographic recorder" to record its meetings.
Arguably, any device used to track record sound or reproduce recorded audio could be called a type of "phonograph", however in common practice the word has come to signify historic technology of sound taking, concerning audio-frequency modulations of any physical track or groove.
In the past due 19th and early 20th ages, "Phonograph", "Gramophone", "Graphophone", "Zonophone" and the like were still brand names specific to various manufacturers of sometimes completely different (i.e. cylinder and disk) machines; so extensive use was made of 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 confusion both and today then.
In British English, "gramophone" may make reference to any sound-reproducing machine using disc records, which were popularized and introduced 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, however in 1910 an English court decision decreed it had turn into a generic term; it has been so used in the united kingdom and most Commonwealth countries ever since. The word "phonograph" was usually restricted to machines that used cylinder records.
"Gramophone" generally referred to a wind-up machine. After the introduction of the softer vinyl fabric files, 33 1/3-rpm LPs (long-playing documents) and 45-rpm "single" or two-song information, and EPs (extended-play recordings), the common 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 British, "record player" was the term; "turntable" was a more technical term; "gramophone" was limited to the old mechanised (i.e., wind-up) players; and "phonograph" was used as in British English.
