Abstract
This invention is a multiple segment flextensional transducer shell that is easily and quickly manufactured and modified. The shell may comprise two adjustable, flexible plates and two buttress bars or two J-shaped adjustable, flexible plates. When the buttress bars and plates or the J-shaped members are connected together at or near the nodal points of the transducer, the assembled shell will have the same shape as the flextensional transducer shells used in the prior art. The open ends of the assembled transducer shell are covered with flanges and a boot is placed over the shell and flanges to make the interior of the shell air tight.
