Abstract
Fixing of a voice coil ( ) to a diaphragm ( ) is performed by caulk-fixing a coil supporting member ( ) to the diaphragm ( ) and by fit-supporting the voice coil ( ) by the coil supporting member ( ). Hereby, the voice coil is physically fixed to the diaphragm ( ) and its fixing strength is heightened. The caulk-fixing is performed by subjecting a caulking projection of the coil supporting member ( ) to a plastic deformation thereby to provide a caulk-fixed portion ( ), whereby deformation injurious to the acoustic property does not occur in the diaphragm ( ). Further, the fit-supporting is performed by interposing a flange portion ( ) formed at an upper end portion ( ) of the voice coil ( ) between an engaging portion ( ) of the coil supporting member ( ) and a central flat portion ( ) of the diaphragm ( ) and holding it by them from upper and lower sides.
