Playback was achieved by specifically repeating the recording technique, the only real big difference getting which the recorded foil now served to vibrate the stylus, which transmitted its vibrations to your diaphragm and onward in the air as audible seem. While Edison's see this quite initially experimental tinfoil phonograph made use of different and to some degree distinctive recording and playback assemblies, in subsequent machines one diaphragm and stylus served each reasons.
