Abstract

A driving circuit of a piezo-electric buzzer comprising: a piezo-electric element (7); a series arrangement of a coil (8) and a unilaterally conductive device (9), the series arrangement (8, 9) being connected in parallel with the piezo- electric element (7); first switch means (5) arranged to be operated by a first signal ( phi 1) so as to supply periodically current to the coil (8); and second switch (6) arranged to be operated by a second signal (???2) so as to discharge periodically a voltage which develops across the piezo-electric element (7) in response to the said current. <IMAGE>
