Abstract
A film speaker includes a metal foil; a diaphragm apart from and opposed to the metal foil; an elastomer for supporting the diaphragm; and a voice coil disposed on the metal foil for producing magnetic field. The diaphragm includes a substrate layer and a magnetic material layer attached to a surface of the substrate layer for interacting with a magnetic field produced by the voice coil so as to drive the diaphragm to vibrate for generating sound.
