Patent ID: 7447327

Claim:
An electroacoustic transducer comprising: a diaphragm; a voice coil which is fixed to a lower face of the diaphragm and has a pair of coil terminals elongating therefrom; a frame which supports an outer peripheral edge portion of the diaphragm; a pair of terminal members which are attached to the frame; and a conductive member which electrically connects the pair of terminal members to the pair of coil terminals, respectively, wherein the conductive member is configured by a flexible printed circuit board in which a pair of conductive patterns are formed on an insulating film, the conductive member is electrically conductively fixed to the coil terminals and the terminal members in respective end portions of the conductive patterns, and in the flexible printed circuit board, a width of an intermediate portion which is located between an end portion on a side of the coil terminals and an end portion on a side of the terminal members is set to be smaller than widths of the end portions; wherein electrical conduction and fixation between the conductive patterns and the coil terminals are conducted by thermocompression bonding, and wherein the thermocompression bonding is preformed by applying heat and pressure to the conductive patterns and the coil terminals, to thereby be self-welded with each other without any solder.
