<p>A drive cone (11) and a vibratory plate (14) are driven in one body by a voice coil (6) movably disposed in a magnetic gap (5). The peripheries of the drive cone (11) and the vibratory plate (14) are supported by a frame (12) through the edge parts (13, 15). A lead wire (21) for loudspeakers used to feed a drive signal to the voice coil (6) are disposed along the surface shape of the edge part (13) supporting the drive cone (11) and adhered along the roll shape with a flexible adhesive. With such a constitution, the lead wire (21) varies its shape according to the variation in shape of the edge part (13) supporting the drive cone (11) when the vibratory plate (14) vibrates. As a result, impartment of bend stress caused by the vibration to a part of the lead wire can be prevented.</p> |
