The bender disc transducer is a kind of low frequency sound source which is widely used in the sonobuoy and disposable underwater acoustic countermeasure equipment. It has the characteristics of low frequency, small size, simple structure and is light in weight. Traditional bender disc transducers with a cavity structure are not suitable in deep water resistance. In order to solve this problem, a...
There are many advantages of broadband transducers, such as reduction of signal distortion, widening the security about information transmission, and reducing the ratio of false codes. The use of three 32-mode single crystal pieces, a thin light beryllium alloy head mass, and a thick heavy tungsten alloy tail mass, can expand the bandwidth of the middle-frequency transducer. The one-third finite element...
