Abstract
The invention provides an improved acoustic energy generating apparatus that includes an improved backing structure. The improved backing structure employs protrusions that are not located in a uniform pattern along a forward side surface of the backing structure, to realize improved re-direction of acoustic energy towards a forward direction relative to the acoustic energy generating apparatus.
