摘要

A new type of the low frequency high power underwater acoustical transducer is described. That is a series of Terfenol-D "Fish-mouth" flextensional transducers with the resonant frequency 210 Hz, 450 Hz, 800 Hz and 1200 Hz. Their transmitting current responses are 160 dB, 162 dB, 166 dB and 170 dB. Their source level is 180 dB, 182 dB, 185 dB and 190 dB. As well as their size and weight (in air) is 600X240X300 mm/28 kg, 400X160X240 mm/11 kg, 240X90X180 mm/4.5 kg and 210X90X160 mm/3.8 kg, respectively.
