摘要：

A novel laminated piezoelectric transducer was mainly composed of the piezoelectric ceramics, metal bolt, rubber gasket, copper electrode, waterproof layer and output cable. The transducer finite-element modeling was built, separately in the air and water, with ANSYS10.0 to calculate the resonance frequency, conductance, transmitting voltage response and directivity. The simulation showed that the laminated structure effectively improved the sensitivity of the piezoelectric transducer. The maximum transmitting voltage respond of the laminated piezoelectric transducer can achieve more than 155dB, compared with a traditional design by approximately 10%.
