SECTIONAL DIFFUSER OF SOUND FIELD IN ACOUSTIC SYSTEM Russian patent published in 2024 - IPC H04R1/28 H04R1/34 

FIELD: acoustics.

SUBSTANCE: acoustic systems sound field sectional diffuser is a dimensional cavity in the form of a ring or a rectangle of a certain height, installed directly in the output hole of the dynamic loudspeaker and (or) the phase inverter of the acoustic systems, inside which there are several similar rings of smaller diameter or radial or parallel planes dividing the cavity of the ring or rectangle into several through sections, areas of cross sections of which are interconnected by a system for calculating a successive ruler of their nominal values by the number of sections and coefficient of their gradation for pairwise distribution of sections with maximum gradation coefficient.

EFFECT: amplification of sound field diffusion, which provides high-quality sounding of phonograms with formation of panoramic sound picture with natural timbre, minimization of distortions and high definition.
