摘要： A piezoelectric device is essentially composed of a piezoelectric transducer and a light transmitting protector. The protector is made of heat resisting glass, heat resisting acrylic, transparent ceramics or the like. By exposing the piezoelectric device to a laser beam and thereby causing it to penetrate through the protector to the piezoelectric transducer and to partly cut the surface of the piezoelectric transducer, or to change the intensity of polarization, mechanical coupling coefficient or dielectric constant of the piezoelectric transducer, its vibration frequency and resonance characteristic can be adjusted. If an ultraviolet-ray setting agent is used as adhesive, it can be hardened by exposing the piezoelectric device to ultraviolet rays to thereby cause it penetrate through the protector.
