Abstract. The effect of low-frequency oscillation in monomorphic piezoelectric elements is considered. Two methods of sound pressure amplification are proposed: separation of piezoelectric element electrodes, and employment of additional oscillatory circuit at the piezoelectric element input.
Keywords:
monomorphic piezoelectric element, low-frequency oscillations, sound pressure, amplitudefrequency characteristic
