Surface boat underwater acoustic signal transmitter having flexing piezoelectric strip underside cap section inside air cavity and outer cap face water exposed

摘要

The broadband acoustic transducer has a flexing piezoelectric strip (101) mounted on a cap (105) set into a cavity (108) with base plate (107). The external face of the cap is exposed to water (106), with the piezoelectric unit mounted on the inner cap face in an air cavity.
