A speaker includes a disk-shaped base. A substantially hemispherical surface vibrator is fitted into a substantially circular groove provided in the base and bonded therein. Terminals are attached to electrodes provided on both surfaces of the vibrator. The terminals, passing through the terminal grooves provided in the base, are led out in a direction that is substantially perpendicular to the plane of the base. Further, a horn as a separate member may be attached to the outer surface side of the vibrator.
