Abstract : The patent application relates to an acoustic transducer for simultaneously producing broadband sound sources in the conventional and overtone resonance modes. Two sets of ceramic and aluminum discs are fixed adjacent each other with the ceramic discs of each set facing one another across an air gap. By selection of respective relative diameters and thicknesses for the ceramic and aluminum discs, the transducer exhibits dual resonance output signals when excited by an input voltage.
