IGB Eletrônica antique phonograph
The phonograph is a device developed in 1877 for the mechanised taking and reproduction 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 saved as equivalent physical deviations of a spiral groove imprinted, etched, incised, or impressed into the surface of an revolving cylinder or disc, called a "record". To recreate the audio, the top is in the same way rotated while a playback stylus traces the groove and is also therefore vibrated because of it, very faintly reproducing the saved sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves that have been 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, lately, turntables), the movements of the stylus are converted into an analogous electric powered signal with a transducer, transformed back to audio with a loudspeaker then.
The phonograph was invented in 1877 by Thomas Edison. While other inventors got produced devices which could record does sound, Edison's phonograph was the first ever to have the ability to reproduce the saved audio. His phonograph at first recorded sound onto a tinfoil sheet twisted around a revolving cylinder. A stylus giving an answer to acoustics 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 throughout the record.
Inside the 1890s, Emile Berliner initiated the transition from phonograph cylinders to toned discs with a spiral groove operating from the periphery to close to the center. Later advancements through the full years included alterations to the turntable and its drive system, the needle or stylus, and the audio and equalization systems.
The disc phonograph record was the dominant audio recording format throughout almost all of the 20th hundred years. Through the mid-1980s on, phonograph use on a standard record player declined sharply due to rise of the cassette tape, compact disc and other digital recording formats. Data are a well liked format for a few audiophiles and DJs still. Vinyl records are still employed 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 re-issued on vinyl fabric sometimes.
Usage of terminology is not uniform across the English-speaking world (see below). In more modern usage, the playback device is called a "turntable", "record player", or "record changer". When used in conjunction with a mixer within a DJ setup, turntables are often called "decks".
The word phonograph ("sound writing") was produced 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 root base were already familiar from existing 19th-century words such as photograph ("light writing"), telegraph ("distant writing"), and phone ("distant sound"). The brand new term might have been affected by the existing words phonographic and phonography, which described something of phonetic shorthand; in 1852 The New York Times transported an advertisements for "Professor Webster's phonographic class", and in 1859 the brand new York State Instructors Connection tabled a movement to "hire a phonographic recorder" to track record its meetings.
Arguably, any device used to track record sound or reproduce registered audio could be called a kind of "phonograph", however in common practice the word has come to signify traditional technologies of sensible tracking, relating audio-frequency modulations of any physical groove or track.
In the past due 19th and early 20th ages, "Phonograph", "Gramophone", "Graphophone", "Zonophone" and the like were still brand names specific to various producers of sometimes completely different (i.e. cylinder and disc) machines; so sizeable 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 lips - a potential way to obtain confusion both then and now.
In British British, "gramophone" may refer to any sound-reproducing machine using disk records, which were popularized and unveiled 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, but in 1910 an English court decision decreed which it had turn into a generic term; it's been so used in the UK & 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 intro of the softer vinyl fabric files, 33 1/3-rpm LPs (long-playing records) and 45-rpm "single" or two-song documents, and EPs (extended-play recordings), the common name became "record player" or "turntable". Usually the home record player was part of something that included a radio (radiogram) and, later, might play audiotape cassettes also. From about 1960, such a system began to certainly be a "hi-fi" (high-fidelity, monophonic) or a "stereo" (most systems being stereophonic by the mid-1960s).
In Australian British, "record player" was the word; "turntable" was a far more complex term; "gramophone" was restricted to the old mechanical (i.e., wind-up) players; and "phonograph" was used such as British English.
