ACOUSTIC WAVEGUIDE Russian patent published in 2019 - IPC G10K11/24 

FIELD: physics.

SUBSTANCE: invention relates to acoustics. Acoustic waveguide comprises a flexible metal rod, to each end of which a cylindrical waveguide is rigidly connected through a conical acoustic concentrator, wherein one cylindrical waveguide is made for connection thereof to the electroacoustic transducer, and the other cylindrical waveguide is made for connection thereof to the receiving device of acoustic oscillations. At the same time the waveguide is equipped with a flexible protective tube, which is sealed, the tube covers both a flexible metal rod and conical acoustic concentrators.

EFFECT: technical result is high functionality of acoustic waveguide, using it in devices operating in high temperature, radiation, powerful electromagnetic interference and other negative factors.
