Abstract
A method for forming a layered structural member may include providing a first outer layer of material and a second outer layer of material, placing between the first outer layer and the second outer layer a layer of core material, and placing between the first outer layer and the second outer layer a piezoelectric transducer, the piezoelectric transducer configured to convert an audio signal received by the piezoelectric transducer into at least one of a mechanical pressure, acceleration, strain and force causing the layered structured member to generate sound.
