 note = {論文(Article), Abstract : Piezoelectric vibrators have been widely used in such devices as ultrasonic motors, piezoelectric pumps, piezoelectric speakers, micro machines and so on. For piezoelectric speakers and pumps, two types of vibrators, bimorph and unimorph vibrators are used. In this report, for improving the productivity and the performance of vibrators, the vibrations of bimorph and unimorph circular piezoelectric vibrators are analyzed theoretically, and their vibration characteristics are discussed by comparing the analytical results.},
