of a DJ setup, turntables are often colloquially called "decks". In later electric phonographs (more often known since the 1940s as record players or turntables), the motions of the stylus are converted into an analogous electrical signal by a transducer, then converted back into sound by a loudspeaker. The term phonograph ("sound writing") was derived from the Greek words (, 'sound' or 'voice') and (, 'writing'). The similar related terms gramophone (from the Greek 'letter' and 'voice') and graphophone have similar root meanings. In British English, "gramophone" may refer to any sound-reproducing machine using disc records, which were introduced and popularized 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 that it had become a generic term; United States In American English, "phonograph", properly specific to machines made by Edison, was sometimes used in a generic sense as early as the 1890s to include cylinder-playing machines made by others. But it was then considered strictly incorrect to apply it to Emile Berliner's Gramophone, a very different machine which played nonrecordable discs (although Edison's original Phonograph patent included the use of discs.) Australia In Australian English, "record player" was the term; "turntable" was a more technical term; "gramophone" was restricted to the old mechanical (i.e., wind-up) players; and "phonograph" was used as in British English. The "phonograph" was first demonstrated in Australia on 14 June 1878 to a meeting of the Royal Society of Victoria by the Society's Honorary Secretary, Alex Sutherland who published "The Sounds of the Consonants, as Indicated by the Phonograph" in the Society's journal in November that year. On 8 August 1878 the phonograph was publicly demonstrated at the Society's annual conversazione, along with a range of other new inventions, including the microphone. Early history Phonautograph The phonautograph was invented on March 25, 1857, by Frenchman Édouard-Léon Scott de Martinville, an editor and typographer of manuscripts at a scientific publishing house in Paris. One day while editing Professor Longet's Traité de Physiologie, he happened upon that customer's engraved illustration of the anatomy of the human ear, and conceived of "the imprudent idea of photographing the word." In 1853 or 1854 (Scott cited both years) he began working on "le problème de la parole s'écrivant
