Abstract
A piezoelectric speaker is disclosed, comprising an elastic base, a piezoelectric material bender, and an acoustical linkage mounted to both the elastic base and the bender and serving to interconnect the elastic base and the bender. The acoustical linkage is fabricated from a rigid material and is mounted to the bender at approximately the geometric center of the bender. The bender may also be encapsulated by a case. The elastic base may include a computer keyboard, a bicycle helmet, a pen, a desk, a computer monitor or any other similar structure.
