cylindrical piezoceramic transducer, internal screen, sound emissionAbstract
Analytical relations are given and on their basis, the properties of the mechanical fields of cylindrical piezoceramic transducers with internal acoustic soft screens are investigated by numerical methods. Established in a wide frequency range, the regularities of the behavior of the frequency and angular dependences of the amplitudes and phases of the oscillatory velocity on the screen size and the degree of its removal from the center of the piezoceramic transducer shell.
