ELECTRODYNAMIC EMITTER Russian patent published in 2023 - IPC H04R9/06 H04R7/04 H04R7/14 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics. The electrodynamic emitter in accordance with the first embodiment contains a frame on which two pairs of jaws are fixed, located at least on one side of the frame and made with the possibility of adjusting the position and fixing along the longitudinal axis of the frame, a magnetic system located on the frame with at least one side and made of permanent magnets, and at least one terminal board for connecting conductors to an electric circuit. Moreover, a diaphragm is fixed between the jaws, at least on one side of which conductors are applied, permanent magnets on the frame and conductors on the diaphragm are located diagonally at an angle to the longitudinal axis of the frame, while the angle of inclination of the permanent magnets and the angle of inclination of the conductors to the longitudinal axis of the frame are equal and are in the range from 1 to 89 degrees, and the surfaces of said jaws, between which the diaphragm is fixed, are made with a profile in the form of periodic sinusoidal waves, and when the diaphragm is tensioned, said surfaces of the jaws provide the formation of corrugations on the diaphragm.

EFFECT: increase in the acoustic power of the emitter, decrease in non-linear distortion, decrease in parasitic resonances, increase in sound dispersion.
