FIELD: mechanical engineering; oil-producing industry; other industries; production and usage of the ultrasonic technological devices. ^ SUBSTANCE: the invention is pertaining to the field of the ultrasonic engineering, in particular, to the processing equipment for ultrasonic treatment, for example, the liquid purification of the objects, impregnation, emulsification, cutting, welding, etc. Specifically, the invention concerns the rod-type resonance acoustical-electrical transducers. The technical result of the invention is provision of the possibility to feed to the acoustic loading located on one side of the transducer of the power from the both strips of the transducer. The device contains the rod-type resonance acoustical-electrical transducer having the piezoelements located between the first and second strips and reinforced by the brace rod; and the acoustic loading connected to one of the strips. Inside the transducer there is at least one cavity open from the side of the first strip and having the bottom formed by the second strip. At that the acoustic loading is connected to the second strip of the transducer inside its cavity. ^ EFFECT: the invention ensures the possibility to feed to the acoustic loading located on one side of the transducer of the power from its both strips. ^ 6 cl, 1 dwg |
