ACOUSTIC SYSTEM Russian patent published in 2020 - IPC H04R1/34 

Abstract RU 2718126 C1

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics. Device consists of low-frequency and high-frequency channels. Low-frequency channel has a lower bend of 105°, a first straight acoustic conductor, a first clutch, inside which a loudspeaker is rigidly fixed, a second direct duct, a first indirect sound duct, a third straight acoustic conductor, a rubberized metal ring, second hollow coupling, second indirect sound guide, second rubberized metal ring, fourth straight acoustic conductor, upper bend 105°. High-frequency channel consists of: lower branch 75°, a first direct sound guide, a coupling with a loudspeaker fixed inside it, a rubberized metal ring, a second direct sound duct, upper bend 105°. To fix the acoustic system, a rigid support and elastic bundles are used, which makes it possible to suspend couplings with a loudspeaker on a low-frequency channel and to reduce resonances. Rigid support is made in the form of a frame, on it tubular structures of the acoustic system are fixed; high-pass filter; elastic bundles.

EFFECT: technical result is reduction of acoustic distortions and resonances.
