ULTRASONIC PIEZOCERAMIC TRANSDUCER Russian patent published in 2012 - IPC B06B1/06 H04R17/00 

FIELD: physics.

SUBSTANCE: invention relates to ultrasonic equipment and specifically to piezoceramic transducers, and can be used in designing novel acoustic systems as well as in existing equipment based on piezoceramic transducers. The ultrasonic piezoceramic transducer has a pack of piezoceramic plates with a metallic insert in between and tied up by a connecting piece between frequency-reducing pads. The total length of the transducer is equal to the wavelength of the rated frequency of ultrasonic oscillations and the maximum diameter of the metallic insert must not be greater than a third of the wavelength of its operating frequency. The metallic insert is made from high-density material, based on the condition of its maximum wave resistance, and the frequency-reducing pads are made from material with minimum possible density, therefore having low wave resistance.

EFFECT: high efficiency of conversion and stability of operating, as well as simple design.
