Claims (1)

[Claims for Utility Model Registration] 1. A damper having a concentric wave corrugation, a conductive part is provided along the corrugation shape from the inner circumference to the outer circumference, and the conductive part is attached to the frame side. In a wiring structure of a speaker in which a signal input path is electrically coupled to an input terminal connected to a voice coil, a tongue piece extending to a terminal board of the input terminal is provided on the outer periphery of the damper, and a tongue piece extending above the terminal board of the input terminal is provided on the outer periphery of the damper. A wiring structure for a speaker, characterized in that an end portion of the conductive portion extends in a state stuck on a tongue piece, and the end portion of the conductive portion and a terminal lug on a terminal board are coupled. 2. When the end of the conductive part and the terminal lug are connected, the terminal lug is crimped to the terminal board with a part of its crimped part remaining, and the crimped remaining piece protrudes from the terminal board, and the crimped remaining piece and the above-mentioned 2. The speaker wiring structure according to claim 1, wherein the conductive end portion is coupled to the conductive end portion. 3. The speaker according to claim 2, wherein an engaging portion consisting of a hole or a notch is formed at the end of the conductive portion, and the caulking remaining piece is soldered while being engaged with the engaging portion. wiring structure. 4. The speaker wiring structure according to claim 2, wherein the caulking remaining piece is bent to be connected to the end of the conductive part.
