Abstract
An acoustic apparatus includes an anchored diaphragm that is actuated by mechanical energy and a transduction material that is disposed in the anchored diaphragm that generates the mechanical energy that actuates the anchored diaphragm. The acoustic apparatus further includes an extendable diaphragm that is actuated when the anchored diaphragm is actuated and a plurality of damping holes that are disposed about the extendable diaphragm and that allow the extendable diaphragm to actuate in a vertical direction.
