AUDIO SYSTEM SYSTEM AND OPERATION METHOD THEREOF Russian patent published in 2016 - IPC H04R1/40 G10K11/34 

FIELD: acoustics.

SUBSTANCE: invention relates to audio systems. Invention discloses an audio system and a method of its operation, wherein disclosed audio system is characterised by that it comprises audio matrix circuit for generating a beam pattern of matrix of audio range using weight coefficients to separate signals of audio range for audio range elements, wherein audio matrix circuit is configured to generate directed output signal by combination of signals from audio range of audio sensors, wherein combination comprises application of weight coefficients to separate audio range of signals; circuit of weight coefficients for determination of weight coefficients in response to presence characteristic; model of movement of user configured to monitor position of a user; and an updating circuit for updating model of movement of a user in response to ultrasonic signals and signals of audio range.

EFFECT: enabling optimisation of sound reproduction for a specific listening position.
