Abstract:
PROBLEM TO BE SOLVED: To attach a diaphragm assembly, consisting of a diaphragm and a voice coil, easily to a unit housing accurately and easily.SOLUTION: Peripheral edge of a diaphragm 6 is bent upward while a lower protrusion 6a is formed downward toward the end side thereof. At the opening edge of a unit housing 9, a support base 9b abutting against the lower protrusion of the diaphragm is formed, and a recess 9a with which the peripheral edge 6b of the diaphragm can engage is formed in the inner side face.
