Loudspeaker enclosure with a closed and an open position

Abstract

A loudspeaker enclosure (1, 1', 1'', 1''' 1a, 1b, 1c, 1d) comprising speaker carrying parts (2, 3, 4, 17, 18, 19, 21, 22, 23, 30, 31, 32, 33) moveable towards each other and each comprising at least one speaker (5, 6, 7, 21 ', 22', 23', 1c', 1d') with an active sound-emanating area (8, 9, 10, 2''', 11'', 30', 31 ', 32', 33'), wherein in the closed position of the loudspeaker enclosure (1, 1 ', 1'', 1''' 1a, 1b, 1c, 1d) the active sound-emanating area (8, 9, 10, 2''', 11'', 30', 31 ', 32', 33') of the at least one speaker (5, 6, 7, 21 ', 22', 23', 1c', 1d') of at least one of the speaker carrying parts (2, 3, 4, 17, 18, 19, 21, 22, 23) is covered and turned towards the rear side of another one of the speaker carrying parts (2, 3, 4, 17, 18, 19, 21, 22, 23, 30, 31, 32, 33).

Description

technical field [0001] The invention relates to a speaker enclosure having a closed and an open position, said speaker enclosure comprising speaker carrying parts movable towards each other and each comprising at least one speaker having an active sound emitting area. Background technique [0002] A loudspeaker enclosure with an open and a closed position is known from document DE 39 15 204 A1. According to this document, the loudspeaker enclosure comprises a rectangular loudspeaker housing with a front panel carrying a woofer. The front and vertical side panels have openings containing independent speakers supported to pivot between a closed storage position and an open operating position about an axis parallel to and proximate to the front edge of the speaker housing. Rotation, wherein in the closed storage position, the loudspeaker is arranged flush with the outer surface of the loudspeaker housing, and in the open working position, the loudspeaker protrudes vertically. ...

AI Technical Summary

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
