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 polymer magnetic material layer and a metal foil reinforcing layer attached to a surface of the polymer magnetic material layer for interacting with the magnetic field produced by the voice coil so as to drive the diaphragm to vibrate for generating sound.
