An oscillator circuit comprising a transistor, a piezoelectric element and a D.C. source, such as a battery, said transistor being common collector mounted and said piezoelectric element being disposed between the base of said transistor and a first terminal of said D.C. source, characterized in that it is adapted so that the response of said oscillator is ensured by a capacitive impedance comprising exclusively the capacitance of the base-emitter junction of the transistor, the voltage of the source being at most equal to 1.5V.
