A flextensional sonar transducer assembly includes a stack of piezoelectric elements disposed along a linear axis, a plurality of electrodes disposed between the elements, end pieces disposed at each end of the piezoelectric stack, with the end pieces having outwardly facing, generally arcuate surfaces, a compression band formed into a loop to encircle the stack and end pieces, a flexural shell disposed to circumscribe the compression band to present a generally elliptical side cross-section, with the major axis thereof being generally coincident with the linear axis of the stack, and with the shell being reactively coupled to the arcuate end portions of the compression band, and rod members positioned between the compression band and the arcuate end portions of the band of material for maintaining driving contact between the shell and the end pieces, and for adjusting the prestress compression pressure in the stack. The invention also includes methods of manufacturing the transducer assembly.

A flextensional sonar transducer assembly including a stack of piezoelectric elements disposed along a linear axis, a plurality of electrodes disposed between said elements, means for conducting electrical signals to and from said electrodes, end pieces disposed at each end of said stack, said end pieces having outwardly facing arcuate surfaces and center apices, a compression band formed into a loop to extend along one side of said stack, arcuately about one of said end pieces and back along the other side of said stack, and arcuately about the other of said end pieces to said one side, a flexural shell disposed to circumscribe said compression band to present an elliptical side cross-section, with the major axis thereof being coincident with said linear axis, and said shell being reactively coupled to the arcuate end portions of said compression band so that an inwardly directed transverse movement of the long sides of said shell toward said stack, allows for longitudinal expansion of said stack, and an outwardly directed transverse movement of the long sides of said shell away from said stack, causes longitudinal compression of said stack, and means positioned between said compression band and at least one of said end pieces for urging the compression band away from the end piece to thereby produce a tensile stress in the band and a compressive stress in the stack whereby, said urging means maintains driving contact between said stack and said shell through said compression band.
