Abstract: y important. Such sensors are characterized by high sensitivity and linearity of the amplitudefrequency characteristic in a wide frequency range. Issues of improving piezoceramic electroacoustic transducers using the method of additional elements are considered in this paper. If the additional oscillatory circuits, which are created using the additional inductance and the interelectrode capacitance of the piezoelectric element, are connected to a relatively high-frequency transducer, it is possible to create acoustic low-frequency oscillations. Also can increase the sound pressure level, expand the bandwidth of the transducer, which is important for transducers used in medical acoustics. Transducers with the properties of differentiating and integrating circuits can be obtained by connecting active resistances to the piezoelectric element.
