CONTROLLED ELECTROMAGNETIC DYNAMIC EMITTER OF ELASTIC WAVES OF LOW FREQUENCY IN NON-CONDUCTIVE MEDIA Russian patent published in 2023 - IPC G01V1/04 

FIELD: acoustics.

SUBSTANCE: controlled electromagnetic dynamic emitter of elastic low-frequency waves in non-conductive media consists of an axis assembled from two ferromagnetic sections, which are the cores of two solenoids, as well as an axis of two dampers and nuts that fix a permanent magnet located between the solenoids fixed on the emitter housing, and a section of diamagnet, which is the axis of a permanent magnet.

EFFECT: ability to control the emitter in the entire range of operating frequencies, variable in power and amplitude.
