Abstract

A source of electrical potential (1) is connected to two parallel circuits. Each circuit comprises an inductor coil (2, 2'), a diode (3, 3') and a switching transistor (T1, T2). A piezoelectric buzzer (4) is connected between the two diode to transistor junctions (B, B'). The two switching transistors (T1, T2) are supplied with signals (S1, S2) which make them alternately conduct and block. When one transistor (T2) conducts and the other (T1) blocks, energy is stored in the corresponding inductor (2') which is then applied to the buzzer as the transistor switching is reversed by the signals (S1, S2).
