what is gramophone or phonograph? A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable,[a] is a device for the mechanical and analogue recording and reproduction of 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 circuit diagram can be found in this video    • ചെടിച്ചട്ടി കൊണ്ട് കോളാമ്പി mic set ഉണ്ടാക...   LM386 ic audio amplifier    • simple ആയി ഒരു audio amplifier ഉണ്ടാക്കാം ...   Subcribe ‪@MrtechElectronics‬ follow me Instagram Facebook how to make gramophone Malayalam diy gramophone gramophone gramophone records disk mechanical sound mr tech electronics #gramophone #diy #make
