ABSTRACT:
A flextensional transducer having an elliptically-shaped shell is compressed at its ends by either piezoelectric or magnetostrictive drive assemblies which are constrained from longitudinal movement by a rigid mount. The compression may be provided by a rigid mount having a gap into which a distended shell and the drive assemblies are inserted. After removing the force producing the distended shell, the mount exerts a compressive force on the ends of the shell. Alternatively, the compression of the shell may be obtained by mechanical forces produced by screw mechanisms forming part of the mount.
