Multi-resonant broadband Janus-Ring transducer

SUN Shuzhen  LI Junbao  
【摘要】:A Janus-Ring(JR) transducer with two piezoelectric rings placed around a Janus driver is presented.The rings have radial vibration,whereas the Janus has longitudinal vibration,and a resonance of Helmholtz cavity is observed between them.By joining the three resonances,the working frequency bandwidth of the transducer is prominently widened.After simulation using finite element method,a prototype is finally fabricated and tested.Results show that in the working frequency of 1.8 to 8.0 kHz,the maximum transmitting voltage response(TVR) is 144 dB,and the fluctuations are less than 6 dB.Compared with traditional Janus-Helmholtz transducers,the JR transducer has the characteristics of wider bandwidth,greater TVR,and less fluctuations of TVR in working frequency band.
