PIEZOELECTRIC TRANSDUCER APPARATUS ABSTRACT OF THE DISCLOSURE An electroacoustic loudspeaker apparatus is provided including a piezoelectric driver element, the opposed major surfaces of which are acoustically coupled into first and second resonant structures. The first resonant structure exhibits a resonant frequency less than the resonant frequency of the driver and the second resonant structure exhibits a resonant frequency greater than the resonant frequency of the driver thus resulting in a broadened or enhanced frequency response.
