摘要： The object is to provide a bone-conduction speaker and its manufacturing method, wherein: efficiency in production is excellent due to reduction in man-hours needed to produce the speaker's parts; any cumbersome removal operation of grinding dust is eliminated; and, variations in product's lowest resonance frequency derived from variations in diaphragm's thickness are minimized, which contributes to improvement in stability of the product's quality and in reliability of the product. The speaker comprises: a yoke (1) having a center magnetic pole and a voice coil wrapped around the pole; magnets (2) disposed on opposite extensions of the yoke (1) ; diaphragm fixing portions (3) disposed on the other opposite extensions of the yoke (1); the diaphragm (4) fixed to the fixing portions (3); and, a plate yoke (6) fixed to the diaphragm (4) to which the yoke (6) has its outer peripheral edges adjacent to the fixing portions (3) laser-welded.
