Abstract
A modal piezoelectric transducer that is constructed with at least three multi section piezoelectric structures to which a shell with equal concave or indentation sections is attached at the intersections of the piezoelectric structures providing magnified displacement to attached pistons and greater loading of the medium on to the piezoelectric structures producing greater output and a lower resonance frequency. A doubly steered array of steerable modal piezoelectric transducers is steered in the same direction as the array is steered.
