QUICK-RELEASE MODULE FOR MAGNIFYING MAGNETIC INDUCTION IN THE MAGNETIC GAP OF AN ELECTRODYNAMIC LOUDSPEAKER Russian patent published in 2022 - IPC H04R9/02 

FIELD: electroacoustics.

SUBSTANCE: invention relates to electroacoustics, namely to electrodynamic loudspeakers. The electrodynamic loudspeaker contains at least one permanent magnet, at least one upper magnetic field concentrator, at least one lower magnetic field concentrator and a core for the concentration of the magnetic field in the magnetic gap, as well as at least one removable element increasing the cross section of the magnetic field concentrator installed adjacent to at least one of the magnetic field concentrators.

EFFECT: multifunctionality, simplification of the manufacturing technology of the magnetic circuit and dynamics in general, improvement of the heat dissipation characteristics.
