Sound is a wonderful thing. The different sounds we hear are produced by the small pressure difference of the air around us. The wonder is that air can transmit these pressure differences so well and truly over a considerable distance.It is connected by a metal diaphragm to a needle, which scrapes the pattern on a piece of metal foil. When you speak toward the diaphragm, the resulting air pressure difference moves the diaphragm, causing the needle to move, and the movement of the needle is recorded on the metal foil. Then, when you run the needle back on the metal foil, the vibration generated by scraping on the metal foil will move the diaphragm and reproduce the sound. The operation of this pure mechanical system shows how much energy can be produced by vibration in the air!
