Problems solved by technology

[0003] Unfortunately, with the known speaker enclosures described above, it has emerged that the speakers are not well suited for use as small speaker enclosures in the case of portable devices such as portable audio players or cell phones, since the known speaker enclosures The unique folding mechanism greatly limits the number of speakers, and thus limits the effective sounding area of ​​the entire speaker box
Another disadvantage of the known embodiment is that at least a part of the active sound area of ​​the loudspeaker is not available in the closed position of the loudspeaker enclosure, since the active sound-emitting side of the loudspeaker equipped on the front panel is turned outwards in the folded position. well protected

Embodiment Construction

[0034] figure 1 The zigzag folded loudspeaker enclosure 1 according to the invention is shown in the closed position. The loudspeaker enclosure 1 comprises loudspeaker carrying parts 2, 3, 4 containing the loudspeakers 5, 6, 7, which are movable towards each other. The speakers 5, 6, 7 are common speakers known to those skilled in the art. Furthermore, according to a preferred embodiment, the speakers 5, 6, 7 are identical.

[0035] Said loudspeaker carrying parts 2, 3, 4 are connected to each other in such a way that the loudspeaker enclosure 1 is folded from the open position by guided swivel movement, as figure 2 shown.

[0036] Each of the loudspeakers 5 , 6 , 7 comprises an active sound emitting area 8 , 9 , 10 . The sound emitting directions of the loudspeakers 5, 6, 7 are substantially the same in the closed position, in which the loudspeaker enclosure 1 is folded.

[0037] In the closed position of the loudspeaker enclosure 1, the active sound emitting areas 9 an...
