Abstract

PURPOSE: To reduce the air gap, by constituting the voice coil with foil conductor and coupling the foil conductor in two stages toward the moving direction of the coil.
CONSTITUTION: The voice coil 3 is fixed to the diaphragm 1 via the bobbin frame 21. In the coil 3, the foil conductor is laminated by the width (a) to form the voice coil unit l and this is coupled in two stages. Since the unit l is coupled by two stages toward the moving direction of the voice coil, it is not required to increase the air gap and accordingly, no need for the large sized magnet 5.
