    Abstract: A low frequency underwater sound electro-mechanical transduction bender apparatus for radiating sound at deep submergence depths and including at least one piezoelectric bilaminar or trilaminar beam or disc having opposed support ends; a pair of piezoelectric structures that each have sides that are respectively connected at the opposed support ends of the beam or disc. The piezoelectric bilaminar or trilaminar beam or disc is driven by the pair of piezoelectric structures. The apparatus further includes a housing that contains the piezoelectric bilaminar or trilaminar beam or disc and the pair of piezoelectric structures, as well as an internal fill of a fluid substance. The housing further defines a reflective rear plate that is positioned opposite to the piezoelectric bilaminar or trilaminar beam or disc for reflecting off of it and returning back to the rear section of the frontal disc or beam or a reflective surface from which back radiation from the bender disk reflects at an angle of 45 degrees and travels radially outward or a reflective surface from which back radiation of the bender disk reflects at an angle of 45 degrees and travels radially outward.
