  • Broadband underwater acoustic transducer
    Patent number: 8027224
    Abstract: An efficient, broadband, underwater acoustic transducer having nominally a quasi-omnidirectional radiation pattern is realized with a plurality of thin walled radially vibrating hollow spherical piezoelectric transduction elements aligned axially. Each spherical transduction element is progressively smaller in diameter so as to enhance the combined frequency coverage and achieve the desirable radiation pattern. The transduction elements may be excited individually, or together electrically in series or in parallel combinations.
