Abstract (en)

[origin: EP0217278A2] In this arrangement, the horn length at least corresponds to the mathematical horn length, the area of the horn neck is at the most 40 % of the mathematical horn neck area and the area of the horn opening is at least 30 % smaller than the mathematical horn opening area. The horn can be partially formed by a corner of the living room, by the shelf, the rear window and one side window of a motor vehicle. The invention includes folded and linear horns. The required volume is considerably reduced by the invention.
