<p>A speaker (10, 50) includes a disk-shaped base (12). A substantially hemispherical surface vibrator (22) is fitted into a substantially circular groove (16) provided in the base (12) and bonded therein. Terminals (30, 32) are attached to electrodes (26, 28) provided on both surfaces of the vibrator (22). The terminals (30, 32), passing through the terminal grooves (18, 20) provided in the base (12), are led out in a direction that is substantially perpendicular to the plane of the base (12). Further, a horn (40) as a separate member may be attached to the outer surface side of the vibrator (22). <IMAGE></p> |
