Abstract
A vibrator includes a voice coil and a vibrating member (20) supported by first and second suspensions (3, 5) so as to be vibratory in the axial direction of the coil. Each of the first and second suspensions (3, 5) has an inner ring portion (11) fixed to the vibrating member (20) and an outer ring portion (12) fixed to a casing of the vibrator. The inner and outer ring portions (11, 12) are connected through arcuate portions (13, 23). Each arcuate portion has a first end connected to the inner ring portion (11) and a second end connected to the outer ring portion (12). The arcuate portions (13, 23) of the first and second suspensions extend from the first end to the second end, respectively, in the same circumferential direction as seen from one side of the axial direction. This prevents the vibrating member turning or rotating as moves in the axial direction, and so improves the resonant behavior of the vibrator (fig 5).
