ULTRASONIC SEPARATE-COMBINED TRANSDUCER Russian patent published in 2024 - IPC H04R17/00 G01N29/24 

FIELD: acoustics.

SUBSTANCE: separate-combined transducers. The ultrasonic separate-combined transducer is a prefabricated structure, including a base on which the following are installed in series: a housing of the radiating unit, in which a prism of the radiating piezoelectric element is placed with at least one radiating piezoelectric element fixed on it; an insulating screen that contains at least one shielding layer - acoustic or electromagnetic, or simultaneously several shielding layers in their various combinations and pairings; the housing of the receiving unit, in which the prism of the receiving piezoelectric element is placed with at least one receiving piezoelectric element fixed to it, while all structural elements are rigidly connected to each other using a fixing element. In addition, elements of a working fluid supply system can also be installed on the same base, ensuring acoustic contact of the ultrasonic separate-combined transducer with the surface of the test object.

EFFECT: increase in operational characteristics, namely the reliability and maintainability of an ultrasonic separate-combined transducer.
