A piezoelectric speaker is disclosed. The speaker includes a rigid structure, a piezoelectric material bender, and a wave guide mounted to both the rigid structure and the bender and serving to interconnect the rigid structure and the bender. The wave guide is a fabricated from a rigid material and is mounted to the bender at approximately the geometric center of the bender. The bender is also encapsulating a case. The rigid structure may include a computer keyboard, a bicycle helmet or any other rigid structure.
