An underwater acoustic projector comprising a pair of spaced apart end plates with an acoustic driver positioned between the end plates, the driver having smaller cross-sectional dimensions than the end plates. The end plate's edges are secured to an outer one-piece thin walled shell that provides a waterproof enclosure for the driver. That thin walled shell has a concavely inwardly bent surface between the end plates and a plurality of axially extending corrugations to provide a predetermined axial compliance and radial-to-axial transformation ratio. |
