3. The highest emission response of the stacked spherical acoustic transducer can reach 156dB, and the highest sound source level can reach 202dB, which is more than 6dB higher than ordinary spherical transducers of the same size.

4. single-crystal vector hydrophone transducer

 

Compared with piezoelectric ceramic transducers, the size of PIN-PMN-PT single crystal transmitting transducer is reduced by more than 1/3, the transmitting voltage response level is 2~10dB higher, the impedance bandwidth is about twice higher, and the -3dB bandwidth is about two times higher. Times; the receiving sensitivity is 3~5dB higher. The single crystal vector hydrophone has low motion self-noise, and the sensitivity is 4~6dB higher than the piezoelectric vector hydrophone of the same size.

 5.Fixed installation vector hydrophone

 

Using the center column as the fixed base, the ceramic shearing working mode, the working frequency band is 100-5000Hz, the installation is simple, the performance is stable, and it can replace most vector hydrophones installed on various platforms.

The cone-shaped reflector is used to reflect the circumferentially radiated sound waves of the toroidal transducer to the end surface to work, and relatively stable acoustic radiation of the beam can be realized on the end surface.
