    Abstract
  • Base on the conventional fabrication technique of piezoelectric ceramic and the design rule of cymbal transducer,forming dies for metal caps of cymbals including low frequency cymbal transducers are developed, the characteristics of different glues and metal materials are compared respectively. Following the method for making cymbal transducers and the key fabrication technique, a series of cymbal transducers are developed. Then the resonance frequency, transmitting voltage response(TVR),free field voltage sensitivity(FFVS) of the low frequency cymbal transducer are tested in an anechoic tank.The results show that the low frequency cymbal transducers have better effect of reception.The FFVS of single cymbal transducer with 5 kHZ frequencyis in the range of -170 ~-150 dB for the working frequencies from 0 to 40 kHz.Also TVR gets to 135 dB,which can be enhanced by cymbal transducer array.This study may provide a refrerence for developing new cymbal transducer.
