Kind Code:
B2
Abstract:
A diaphragm of a loudspeaker is composed of a plate-shaped diaphragm body and a ring-shaped reinforcing part, both of which are bonded to each other. The reinforcing part is provided with a groove that is recessed from a joint surface of the reinforcing part, and the joint surface is joined to the diaphragm body. The groove causes an inner periphery of the reinforcing part to communicate with an outer periphery of the reinforcing part. A connecting wire passes through the groove to electrically couple a voice coil and a terminal disposed to the frame together. The voice coil is attached to the back surface of the diaphragm body.
