A phonograph, later called a gramophone, and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of recorded sound. 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.

फोनोग्राफ ध्वनि के अभिलेखन के लिए काम में लिया जाने वाला एक उपकरण है जिसका आविष्कार १८७७ में हुआ। वर्तमान में इसे ग्रामोफोन अथवा रिकॉर्ड प्लेयर के रूप में भी जाना जाता है। इसका आविष्कार थॉमस एडीसन ने किया था।
