Abstract:
A system for coupling sound energy to a liquid, comprising:at least two transducers forming a transducer array adapted for coupling to a liquid in a container, the transducer array constructed and arranged so as to be capable of producing intense sound energy in the liquid at any frequency within at least two non-overlapping frequency bands;a signal generator adapted for producing a driver signal for driving the transducer array at any frequency from one or more continuous frequency ranges within each of the at least two frequency bands;wherein the signal generator drives the transducer array to produce the intense sound energy characterized by a series string of different frequencies within one of the continuous frequency ranges, the generator further drives the transducer array to discontinuously jump amongst the frequency ranges, so as to generate intense sound energy characterized by a series string of different frequencies within at least one additional frequency range in at least one additional frequency band.
