A sound generator that has a plurality of acoustic piezoelectric transducers coupled to a single Helmholtz resonator. The resonant frequency of the Helmholtz resonator and each transducer can be intentionally chosen to be different so as to be stagger tuned so that the sound generator can create intense sound waves over a broad frequency range.
