Abstract
An acoustic transducer, such as a bender bar, having ferroelectric actuation elements that are designed to optimize a predetermined deflection mode shape. The acoustic transducers may include one or more rounded modally shaped actuation elements or weighted actuation elements. Modal shaping of the actuation elements allows for specific targeting of modes which most efficiently radiate acoustic energy.
