Abstract
The Class IV flextensional transducer is a typical low frequency, high-power and small size transducer. The bandwidth of the Class IV flextensional transducer is narrow for its high mechanical quality factor. For improving its bandwidth capability, a configuration of broadband flextensional transducer was proposed according to the theory of multiple-mode-coupling. The transducer driven by piezoelectric ceramic PZT-4 was designed and analyzed using finite element software ANSYS. The transmitting voltage response of the transducer reached to 131.5dB with ripple 11dB from 1 kHz to 6.5 kHz based on the simulated results. The purpose of extending the bandwidth of the flextensional transducer could achieve.
