AUDIO SYSTEM Russian patent published in 2019 - IPC H04R5/02 

Abstract RU 2710524 C2

FIELD: physics.

SUBSTANCE: invention relates to acoustics, in particular to acoustic systems. Computing unit for a sound system comprising an array with a plurality of transducers, wherein the computing unit comprises: an input means for receiving an audio stream, a processor and an audio output means. Processor is configured to calculate a first plurality of separate audio signals for array converters such that lasing is performed by an array of transducers. Processor is configured to calculate a second plurality of separate audio signals for suppressing direct sound such that the sound is neutralized in the listening direction. Processor is configured to filter a second plurality of separate audio signals. Lining is performed by using three audio signals so that at least three converters are controlled. First plurality of audio signals and the second plurality of audio signals are summed up using a mixer.

EFFECT: technical result is improved reproduction of surround sound using audio system.
