Phonograph
The gramophone, invented by Emile Berliner, plays sounds from a flat disk record. The record is placed onto the turntable. The turntable spins the record while a lever with a small needle on the bottom lies between the little grooves in the disk. When the grooves make the needle vibrate, music is played. These machines do not record, but the disks could be copied quickly onto vinyl disks in a factory with a mold, called a master.
