HIGH-INTENSITY AUDIO GENERATOR Russian patent published in 2019 - IPC B06B1/00 

FIELD: physics.

SUBSTANCE: invention relates to acoustics. Sound oscillation generator comprises a first body made with at least one variable area cross-section channel, decreasing gas or mix of gases and/or substance in gaseous state in direction of movement, wherein channel is intended for passage of said flow, second body installed along flow direction after first body and comprising at least one channel, intended for passage of said flow, coming from first body, third body installed along flow direction after second body and made with possibility of rotation relative to second body, wherein the first body is a pipe or a shell, inside which a coaxial element is installed coaxially with it. Sound oscillation generator comprises a first body made with at least one variable area cross-section channel, decreasing gas or mix of gases and/or substance in gaseous state in direction of movement, wherein channel is intended for passage of said flow, second body installed along flow direction after first body and comprising at least one channel, intended for passage of said flow, coming from first body, and made with possibility of rotation relative to first body, wherein the first body is made in the form of a cylinder, in which along the flow direction there are through channels providing the flow passage, besides, the inlets and / or outlets of the channels are located in at least one circle.

EFFECT: technical result achieved when implementing the developed device consists in increasing the amplitude of pressure pulsation.
