摘要 |
There is provided a method of manufacturing a loudspeaker damper having the steps of attaching a conductive material to a damper raw material at the top or bottom surface thereof, the damper raw material being made of a woven or unwoven cloth impregnated with thermosetting resin such as phenol resin and being made in a semi-dry state, and thermally molding the damper raw material with the conductive material to form concentric corrugation along which conductive material used as a conductive wire for a voice signal is formed, wherein the method further including the steps of: after attaching the conductive material to the damper raw material, coating creamy solder to the conductive material at a predetermined area, melting the creamy solder by the heat at the thermal molding step, detaching the damper raw material from a metal mold to cool and harden the creamy solder, and forming preparatory solder at the end portion of the conductive material. |
