CYLINDER-TYPE UNDERWATER TRANSDUCER

摘要

FIELD: physics; acoustics. ^ SUBSTANCE: cylinder-type underwater transducer comprises one piezoceramic ring or several piezoceramic rings. In the transducer, piezoceramic cylinder is of variable circumferential thickness; axes of cylinder outer and inner surfaces are offset as regards to each other. ^ EFFECT: provides for directional radiation at any depth; simplified design. ^ 2 dwg
