ABSTRACT:
The invention concerns a loudspeaker housing (1), particularly for rendition of the deep and middle tone ranges, having a loudspeaker (27) and a folded flare (14; 20, 21, 15, 16; 6). The front side of this loudspeaker housing (1) has an upper area, in which the loudspeaker (27) is located, as well as a lower area, which represents the end of the folded flare. The tones with higher frequency are thus radiated directly from the loudspeaker (9, 27) forwards, while the low frequency tones are radiated via the folded flare, whereby this flare guides the sound waves generated by the loudspeaker (9, 27) towards the rear wall of the loudspeaker housing (1). Hereby, the flare is formed by an opening (18) in an intermediate wall (17), an arch (14), two guide spacers (20, 21), two arches (15, 16) above the guide spacers (20, 21), and one exponentially curved wall (6) (FIG. 2).
