<P> The phonograph is a device , invented in 1877 , for the mechanical recording and reproduction of sound . In its later forms , it is also called a gramophone ( as a trademark since 1887 , as a generic name in the UK since 1910 ) , 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 '' . To recreate the sound , the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it , very faintly reproducing the recorded sound . In early acoustic phonographs , the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn , or directly to the listener 's ears through stethoscope - type earphones . </P>
