Abstract

PURPOSE:To protect an oscillating repeating lead wire from humidity so as to prevent the disconnection due to corrosion by providing the connection position between a voice coil lead wire and the repeating lead wire and the leading- out point for repeating on the front of a diaphragm. CONSTITUTION:A diaphragm 23 has the peripheral edge part supported by the outer peripheral part of a frame 14 and has the center part supported by a suspension 25 fixed to a voice coil bobbin 18 by adhesion. A repeating lead wire 22 is fixed to a dustproof cap 20 by an adhesive 21. The other end of the repeating lead wire 22 is connected to the voice coil lead wire on the front of the diaphragm 23 by a solder 27. Since the connection point between a leading-out lead wire 24 of a voice coil 26 and the repeating lead wire 22 is placed on the front of the diaphragm, the disconnection due to corrosion of the repeating lead wire 22 is prevented to provide a speaker of high reliability.

When the conventional speaker is used for a vehicle, the frame 1 is attached to the vehicle instrument panel and the magnetic circuit is located inside the door of the vehicle body. Rainwater that has entered through the gap between the window glass of the vehicle body and the vehicle body collects in the magnetic circuit portion. This moisture has a drawback that the relay lead wire 11 is corroded for a long period of time, and mechanical fatigue due to the amplitude of the diaphragm 5 causes the relay lead wire 11 to be disconnected and malfunction.
