Terminal for speaker
Abstract:
A speaker, and its manufacturing method, is disclosed where the speaker includes a speaker component of an integral structure which has a damper made of a base member having concentric corrugations and an opening formed generally at the center thereof and a tinsel wire being disposed around the corrugations, a ring member made of insulating material mounted on the damper, and a voice coil bobbin inserted into the opening of the damper and having a wound coil electrically connected to one end of the tinsel wire. The speaker further includes a terminal lug mounted on the ring member and terminally connected to an end of an input lead wire at one end and to the tinsel wire at the other end, a diaphragm that is coupled to the voice coil bobbin, a speaker frame, and a magnetic circuit fixed to the speaker frame. This speaker and its method of manufacture provide an improved speaker having a damper with a conductive member, reducing the man power required for mounting the input terminal, and improving the quality of the product.
