ACOUSTIC OUTPUT DEVICE AND ITS ACTION METHODS Russian patent published in 2022 - IPC H04R1/10 

FIELD: acoustics.

SUBSTANCE: present invention is an acoustic output device. The acoustic output device may contain an acoustic output component and a support structure forming an acoustically opened structure, which allows for the acoustic output component to acoustically communicate with the environment. The acoustic output component may contain a set of acoustic drivers, each of which can be made with the possibility of sound output in some frequency range. At least one of acoustic drivers may contain a magnetic system for formation of the first magnetic field. The magnetic system may contain the first magnetic component for formation of the second magnetic field and at least one second magnetic component. A magnetic gap can be formed between the first magnetic component and at least one second magnetic component. Voltage of the magnetic field for the first magnetic field in the magnetic gap may be greater than of the second magnetic field in the magnetic gap.

EFFECT: reduction in sound leak and improvement of sound.
