Abstract

Small-sized control circuit using a switching transistor (12) and a positive-booster coil unit (13), with a view to producing a back-electromotive force so as to control a piezoelectric vibrator (14) by means of a voltage greater than the supply voltage, a resistor (R2) of predetermined value being mounted in series with the positive- booster coil unit and attached to the piezoelectric vibrator (14), the said positive-booster coil unit (13) using a wire of higher resistance so as also to serve as a resistor, thus making it possible to miniaturise the whole of the control circuit. <IMAGE>
