What can you tell me about audio speakers and the induction coil theory?

Answer by  DrKlahn (24)

Speakers are diaphraghms connected to a wire coil around a magnet. When current passes through the wire, magnetic forces are induced around the wire, causing the diaphragm to move.

A speaker coil consists of an array of multiple sets of two coils, a main or primary coil and a secondary or auxiliary coil. These coils are use to create high potential current from short-lived electrical current.
