| Abstract: | A new type of Cymbal transducer is presented.Compared with traditional Cymbal transducer,the piezoelectric disk in radial vibration is substituted by a combination of a piezoelectric disk and a metal ring.In this paper, the radial vibration of the combination of a piezoelectric disk and a metal ring is analyzed and its electro-mechanical equivalent circuit is obtained.Based on the radial equivalent circuit,the electro-mechanical equivalent circuit for the Cymbal transducer is derived,and the resonance and a... |
