Descripción:
The phonograph is a device for the mechanical recording and reproduction of sound. In its later forms, it is also called a gramophone or, since the 1940s, a record player. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record".
