A gramophone, or phonograph, is a device that was used for playing recorded sound from the 1870s through the 1980s. More recently, gramophones were called record players or turntables. Gramophones play records, large round, black platters. The original gramophone did not need electricity to run, with the record being turned by winding it up, and the sound was amplified simply by the shape of the "horn" you can see in the picture at the top of the gramophone. The sound itself comes from the vibrations of a small needle, called a stylus, in a spiral groove on the surface of the record.
