The name phonograph was originally given by Edison; the word was derived from Greek words meaning sound or voice. Edison did not work on developing a phonograph but it was invented while he was working on a telegraph machine. Edison had started working on the telegraph machine when he was a teenager. The first phonograph which Edison designed was a small model which used tin foil covered metal cylinder as a record. It had an axle which could be turned and a mouthpiece with a vibrating disc or a diaphragm. A later version had a funnel-shaped earpiece to increase the volume of the sound.
