Abstract

The audiovisual sound system (A) of this invention comprises a screen (1) and a frame (2) surrounding it; a speaker grille (3) on at least one side of the frame (2); and at least one speaker (4) behind the grille (3). In the part of the speaker grille (3) that is left behind the frame (2) is at least one sound diverting system (32) which is constructed in an inward-curving way to direct the audio produced towards the open area; and also, an audio output channel (33) passing through between each sound diverting surface (32) and the grille parts (31) next to it.
