Abstract

Shell (1) for a flextensional transmitter wherein the shell has a cylindrical shape with a near elliptical cross section and wherein the driving elements of the flextensional transmitter, which are centred around the major axis of the elliptical cross section, are connected to end beams (4, 5) fixed to the inside of the end regions (2, 3) of the shell and wherein the shell between the end regions is formed with both bendable (b, d) and stiffened (c) regions.
