Underwater transducer

Using the transducer under the water is named hydroacoustics(underwater) transducer. The electron oscillator produce electric signal to promotes the transducer producing machine vibration,hence driving aqueous medium to transmit sound wave is named as transmit transducer. On the contrary,under the sound wave`s excitation the transducer can produce vibration making the sound enery to electric energy which is named as receiving transducer or hydrophone.
