Beschreibung
Zusammenfassung:	An embodiment of an acoustic transducer assembly includes: a piezoelectric active element configured to emit acoustic signals, the active element having an emitting surface and a back surface located opposite the emitting surface, at least a portion of the back surface having a shape that forms a curve, the shape configured to cause the active element to have a variable thickness between the emitting surface and the back surface; and a backing material disposed in contact with the backing surface and configured to absorb the acoustic signals, the backing material shaped to conform to the back surface.
