摘要：A new class of piezoelectric composite spherical cap transducer that produces a wide beam and bandwidth was developed for underwater acoustics. A finite element analysis (FEA) simulation was ud to design the transducer. Electroacoustic respon measurements in water were made on a transducer to evaluate the performance characteristics and then compared with the FEA results. The measured results show the transducer can provide a 112° beamwidth and a usable frequency band fro迷茫的路

m 215?kHz to 355?kHz. The maximum transmitting voltage respon (TVR) of the transducer is 161.7?dB re 1μPa/V@1m at 255?kHz.
