On the Theory of Flexural Piezoceramic Circular Plate Sound Radiators

Abstract

Circular electrostrictive plates, oppositely polarized and cemented together to form bilamellate disks, are submerged in a semi-infinite medium and driven by an applied electric field, or by applied acoustic pressures, to radiate sound. Formulas for plate velocity, acoustic power radiated, acoustic pressure, mechanical Q, etc., have been derived for the cases of centrally supported and edge supported disks in infinite baffles.
