FIELD: physics.
SUBSTANCE: invention relates to acoustics, particularly to sound panels. Sound panel comprises housing, two converters of first group and at least one converter of second group. At least two converters of the first group are arranged on the front side of the housing and are configured to emit sound in a first direction in accordance with two first audio signals in order to reproduce a two-dimensional sound field. At least one second group converter is arranged on housing second side and is configured to emit sound in second direction in accordance with one second audio signal such that sound emitted by at least one second group converter, achieved preset location of listener in reflected manner, in order to expand two-dimensional sound field in direction of height. Reflection reflecting sound emitted by at least one second group converter is of the order of at least two.
EFFECT: technical result is improved sound characteristics, high realism of reproduction.
