Re: [AI] A glympse into the working of a Gramophone
There was one gramaphone at HKCMM School for the Blind Karimpuzha in Kerala which worked with the force of an woun spring. When the spring is tightened the disc will start to revolve on its tray. A stylus which works as the track reader is set in such a way that it moves in the track of the disc. In the tracks, there is hights and low places in an anologue style as per the recorded sound. So the stylus moves back and forth as the disc revolves.the other end of the stylus is attached to a magnet which moves in a solinoid. Since the stylus moves acording to the recorded audio frequency an audio frequency signal is generated in the solinoid. This signal is coupled to a tiny speaker which serves as the driver of a cone loudspeaker. The specially designed cone loudspeaker, through its impedence matching, gives sufficient volume to the audio output. Even in this digital era, this invention is a real miracle. When I saw the gramaphone for the last time, it could play only for one and a half minute because of its weak spring. Experts were not available to repair it.
