    Abstract
  • To broaden the working bandwidth of an acoustic transducer, improve its transmitting performance and reduce transmitting fluctuation, we designed a novel multi-resonant broadband Tonpilz acoustic transducer by using comprehensively the matching layer, the double exciting, the bending vibration, and slotting on the middle mass block, etc., employed the finite element method to conduct modal analysis of the transducer, and investigated the influences of the thickness of the matching layer and the size of the middle mass block on the performance of the transducer. Test verified that the working bandwidth of the transducer was 12 kHz ~ 42 kHz, the transmission voltage response(TVR) was greater than 140 dB, and the transmission voltage fluctuation in the frequency band was less than 6 dB. Calculation results were in good agreement with the test ones.
