ABSTRACT:
A transducer for use in an acoustic energy cleaner is provided. The transducer includes a resonator and a plurality of crystals bonded to a surface of the resonator. The plurality of crystals is configured to be bonded to the surface of the resonator in a staggered arrangement with respect to each other. In one embodiment, the plurality of crystals is bonded to the surface of the resonator in a horizontally staggered arrangement. In another embodiment, the plurality of crystals is bonded to the surface of the resonator in a vertically staggered arrangement.
