Abstract

PURPOSE:To give the control to the temperature characteristics by applying the stress to the oscillator according to the temperature and after mounting the material having the different heat expansion coefficient from that of the piezoelectric oscillator, thus ensuring the improvement for the temperature characteristics of the oscillator through the simple constitution. CONSTITUTION:Exciting electrodes 2 and 2' are formed to piezoelectric oscillator 1 formed with the crystal or the like. Then materials 3a and 3a' plus 3b and 3b' having the different heat expansion coefficients from that of oscillator 1 are mounted to one surface or both surfaces of oscillator 1. And the stress is applied to oscillator 1 when the temperature exceeds the fixed level and according to the temperature change in order to give the control to the temperature characteristics. Thus the temperature characteristics can be improved for oscillator 1 through the simple constitution.
