1. Underwater electro-acoustical transducer apparatus, comprising:

  • first and second electro-mechanical flexure discs including a radially continuous disc member and a series of concentric electro-mechanical strain translating means affixed to said radially continuous disc member at various radial distances from its center;

    annular spacer means for supporting said first and second electro-mechanical flexure discs in parallel spaced relationshp; and

    means for selectively energizing the concentric electro-mechanical strain translating means with predetermined alternating current signal frequency spectral components, wherein the upper frequency limit of the frequency spectral components varies in inverse relation to the radical distance of the electro-mechanical strain translating means from the center of the radially continuous disc member.
