Abstract
The invention relates to a loudspeaker box (12) comprising a housing (20), a loudspeaker (22) arranged in the housing (20) for generating sound, and a sound-guide device (14), wherein the sound-guide device (14) is arranged in front of the loudspeaker (22) in a sound propagation direction (25), wherein the sound-guide device (14) is configured in such a way that the sound-guide device (14) guides the sound generated by the loudspeaker (22) to a front slot (30) arranged on a front side (27) of the sound-guide device (14) for the purposes of sound radiation. The invention also relates to a column loudspeaker box (10) comprising at least two loudspeaker boxes (12) arranged above one another.
Claims26
A loudspeaker box (12) comprising a housing (20), a loudspeaker (22) arranged in the housing (20) for generating sound, and a sound-guiding device (14),
- wherein the sound-guiding device (14) is arranged in front of the loudspeaker (22) in a sound propagation direction (25), and
- wherein the sound-guiding device (14) is configured in such a way that the sound-guiding device (14) directs the sound generated by the loudspeaker (22) to a front slot (30) arranged on a front side (27) of the sound-guiding device (14) for the purpose of sound radiation, the front slot (30) extending in a longitudinal direction transverse to a sound propagation direction (25) of the loudspeaker box (12),
- wherein the loudspeaker (22) has a loudspeaker diaphragm (23),
- wherein the sound-guiding device (14) has a rear side (41) facing the loudspeaker (22) and having a rear surface (50),
- wherein the rear surface (50) is formed at least in certain regions in the form of a negative impression (52) of the loudspeaker (22) and/or of the loudspeaker diaphragm (23),
- wherein the rear side (41) has a rear slot (42) which is elongated in a longitudinal direction transverse to the sound propagation direction (25) and into which the sound generated by the loudspeaker (22) is introduced, and
- wherein the rear slot (42) is divided into individual openings by at least one rear longitudinal member (46) that extends along the longitudinal direction of the rear slot (42) and by at least one rear transverse member (48) that is transverse to the at least one rear longitudinal member (46).
A loudspeaker box (12) comprising a housing (20), a loudspeaker (22) arranged in the housing (20) for generating sound, and a sound-guiding device (14),
- wherein the sound-guiding device (14) is arranged in front of the loudspeaker (22) in a sound propagation direction (25), and
- wherein the sound-guiding device (14) is configured in such a way that the sound-guiding device (14) directs the sound generated by the loudspeaker (22) to a front slot (30) arranged on a front side (27) of the sound-guiding device (14) for the purpose of sound radiation, wherein the front side (27) has a planar surface in which the front slot (30) is disposed and has at least one edge (38) which begins flush with the planar surface and curves only rearwardly, opposite the sound propagation direction (25), and outwardly from the planar surface, wherein the front slot (30) has a width of between 10 mm and 30 mm, and wherein the at least one edge (38) of the front side (27) of the sound-guiding device (14) is rounded with a radius of from 5 mm to 30 mm.
