In this paper, the coupling vibration of piezoelectric ceramic annular resonators was studied. and the relationship between radial and thickness vibration was analyzed. The frequency equation has been derived, which can be used to calculate the resonant frequencies of finite dimension piezoelectric ceramic annular resonators. The experiments show that, compared with the results of one dimensional theory, the resonant frequencies obtained in this paper are in better agreement with the measured results.
