Abstract
PURPOSE:To lower the resonance frequency without affecting the capacity ratio by polishing the partial electrode surface formed thick previously, and thus obtaining easily the oscillator featuring the desired frequency characteristics. CONSTITUTION:Full electrode 2 is formed at the lower side of the disk-shaped piezoelectric oscillator featuring the oscillation in the diameter direction, and at the same time partial electrode 1 featuring about double thickness of elctrode 2 is formed at the upper part of the oscillator respectively. Then electrode 1 is polished to lower the resonance frequency down to the prescribed level. In such way, the frequency can be adjusted without affecting resonance/antiresonance frequency difference DELTAf and mechanical Qm of the oscillator, thus obtaining the desired resonance frequency.
