ABSTRACT:
A flextensional electroacoustic transducer with end plates and outwardly convex shells connected to form a housing containing a transduction drive member and laterally disposed tensioning members in contact with said end plates. The tensioning members are connected by hinges allowing rotational oscillatory movement of the end plates with respect to said hinges. Another embodiment includes end plate hinges where the end plates contact the transduction drive member and hinges where the shells connect to the end plates.
