The developed compact hydroacoustic radiator with all-metal titanium case of complex shape has no problem with sealing, typical for such kind of transducers, has big effective radiation area and sensitivity as compared to analogs with similar dimensions. Test results of the radiator with active element, having 8 rings 36×14×8 mm of composite "TsTBS-3", showed that such radiator has efficiency about 30%, is capable to radiate acoustic power at the level of 70 Wt in water at resonance frequency of 1.7 kHz, has resource more than 1010 cycles. High power density (above 300 Wt/m3) and band width of 25% allow to apply such a transducer for small-size and miniature hydroacoustic systems, modems, control devices in frequency range from 1.6-2.5 kHz and up to 12-18 kHz.
