Loudspeaker arrangement.

Abstract

The invention relates to a loudspeaker arrangement for creating a three-dimensional stereo sound effect. The loudspeaker arrangement is to be located at a suitable distance from sound-reflecting surfaces. The loudspeaker elements (12a, 13a, 14a; 12b, 13b, 14b) of the left-hand channel (2) and the right-hand channel (3) in the loudspeaker arrangement are located within one and the same loudspeaker unit (1), where they are separated from each other by means of a zone (4) which is at least of the same size as the interval (a) between human ears. The loudspeaker elements are arranged to radiate towards different sides (A, B) of the said zone (4), in a similar fashion, within 180 DEG circle sectors, in which case the sounds reflected from the surfaces, together with the sounds coming directly from the loudspeaker unit, create a depthwise expanded, three-dimensional stereo sound effect, mainly within the sector (10) expanding away from the loudspeaker unit.
