FLARE WAVE-GUIDE PROJECTOR

摘要

An underwater acoustic projector comprising a pair of spaced apart end walls with an acoustic driver positioned between the end walls, the driver having smaller cross- sectional dimensions than the end walls. Each end wall close one end of flared open ended pipe waveguides and is mechanically coupled to one end of a piezoelectric acoustic driver. The flared pipe waveguides extend outward from the driver and have a larger diameter at their open ends than at the end walls.
