FIELD: hydroacoustics and airborne audio engineering. SUBSTANCE: proposed piezoelectric electroacoustic transducer that may be found useful as fast- varying pressure sensors has bimorph piezoelectric plate and air-tight case with two shells disposed at opposite sides of bimorph plate. Ratio of diameter of case supporting members to that of bimorph plate is chosen between 0.65 and 0.75. EFFECT: reduced vibration sensitivity and facilitated manufacture. 1 cl, 2 dwg |
