SINGLE-MANURE ISODYNAMIC RADIATOR Russian patent published in 2020 - IPC H04R9/04 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, particularly to sound emitters. Isodynamic radiator comprises housing with built-in rod permanent magnets arranged parallel to each other, parallel to plane of magnets is fixed flat flexible dielectric thin-film diaphragm with current-conducting path applied on it, long straight sections of the track are parallel to rod permanent magnets, and ends of current-conducting path have electric terminals. Current conductor shape is characterized by that direction along current-conducting path from its beginning to end in all sections of current-conducting path located along magnets on one side relative to central magnet at odd number of magnets located in one plane, coincides, current direction in these sections coincides also, the axis drawn through the central magnet limits the shape of the current-conducting path so that all sections of the current-conducting path located on one side relative to each of the axes cross the second axis on one side, central rod magnets are directed by poles of one sign to each other, non-central magnets on one side relative to the diaphragm are located with different poles to each other.

EFFECT: technical result is high quality of transmitting an audio signal.
