ABSTRACT:
A small-sized buzzer comprises a vibrationally driven vibrator mounted within a case together with drive circuitry for electromagnetically actuating the vibrator. A screw member is threaded into the case at a location spaced from and opposite the free end of the vibrator so as to be repeatedly struck by the vibrator free end during its vibration to produce a buzzer sound. The buzzer sound can be varied by turning the screw member to adjust its spacing from the vibrator.
