Abstract: A diode and a coil are connected in series to the output side of a driving circuit switched ON and OFF upon receipt of a pulse signal and a piezoelectric vibrator is connected in parallel with the series-connected diode and coil. The piezoelectric vibrator is driven by a reverse induced voltage produced in the coil when the driving circuit is switched OFF so as to apply more electric energy for driving the piezoelectric vibrator than would be the case if the diode were omitted.
