INFRASOUND GENERATOR AND DEVICE FOR GENERATING INFRASONIC WAVES Russian patent published in 2021 - IPC B06B1/18 

FIELD: applied acoustics.

SUBSTANCE: group of inventions relates to technical acoustics, in particular to devices for reproducing low-frequency sound waves. Infrasonic generator 1 has a hollow body 2, which has coaxial inlet 3 and outlet 4 openings communicated with the cavity 5 of the housing 2. The cavity 5 of the housing 2 has an oblong shape, elongated along the axes of the inlet 3 and outlet 4 openings and tapering towards them. The modulator 10 is tightly installed in the outlet in the form of a pipe, at least part of which is located in the cavity 5 of the housing 2 and the end of which, facing the inlet 3, has an internal chamfer 12. The device for generating infrasonic waves has a body in which the infrasonic generators 1 are located in such a way so that the axes of their inlet openings 3 are parallel to each other. The body of the device has a channel, at one end of which there is an inlet bell, tapering towards the channel cavity, and at the other end, a movable partition is installed. The channel communicates with the inlets of 3 infrasonic generators 1.

EFFECT: elimination of air losses and increase in power due to the direct flow of air flow.
