| Abstract: | This paper talked about the design of the ultrasonic transducer for underwater detecting on a short distance. It is chase the thickness-oscillation mode transducer. It is made certain the prime optimal working-frequency and the thickness of its wafer in the light of the character factor. The authors make the experiment in a pool, the result showed that the designed hydrophone is possessed of the characteristics such as working trustiness,fine directivity,simple configuration and lower cost,etc. |
