Definitions

  • the invention relates to a loudspeaker in column construction with at least one loudspeaker system, in particular a three-way loudspeaker system, which is surrounded by a columnar housing.
  • Such loudspeaker boxes are used in particular for hi-fi stereo applications in the audio area, but also in connection with the most faithful reproduction of TV or video sounds.
  • the speakers are generally placed in a wall unit or hung on the walls of the room.
  • the assembly is relatively complex since bores have to be drilled to ensure that the loudspeakers, which are sometimes relatively heavy, are held securely.
  • loudspeakers are often set up freely in the room, but the required loudspeaker cables are disruptive and can even cause a trip hazard.
  • the object of the invention is to create a loudspeaker in column construction with which simple assembly, low construction costs and a compact construction are achieved within a furniture system with improved sound radiation.
  • the design of the housing of the loudspeaker box as a supporting column, to which furniture parts are laterally connected and fastened, results in a double use of the loudspeaker box, namely a favorable placement in the corner area of furniture parts, so that excellent sound quality is achieved.
  • the housing of the speaker box also serves as a corner connector for the furniture parts, so that no separate corner posts are required for the furniture are. Rather, the housing of the loudspeaker box is used to anchor the side furniture parts and to support them as a support foot or post.
  • the use of such loudspeaker boxes as reclining furniture corner posts or as seating furniture corner posts is preferred, since this enables particularly intensive and true-to-sound reinforcement of the person lying or sitting on them in stereo reproduction.
  • the top of the loudspeaker can be adjusted in the direction, in particular in the upwardly projecting version of the tweeters, so that directional variations in the sound radiation can also be easily realized.
  • the column-like loudspeaker boxes can also serve as cabinet corner posts, preferably on shelf walls or also as end posts of a banister, a bar counter or a cloakroom.
  • the housing of the loudspeaker box is preferably designed as a round column, the casing being designed as a perforated plate, so that the furniture parts can be secured in a simple and stable manner by means of simple hooking connections engaging in the perforated plate or screw connections screwed from the interior of the round column.
  • the furniture thus created has an extremely decorative appearance with integrated loudspeakers.
  • Fig. 1 four columnar speaker boxes 1 are shown, which serve as corner posts of a bed.
  • the respective loudspeaker box 1 is surrounded by a housing 2, which is preferably designed as a round column 10. Furniture parts 3, in this case the cheeks 3a of the bed, are attached to the housing 2 at each side.
  • the fastening option will be discussed in more detail below in connection with FIG. 2.
  • a housing 2 In the housing 2, an interior 4 (see FIG. 2, right half) is formed, in which a loudspeaker system 5 is arranged.
  • the loudspeaker system 5 is preferably designed as a three-way loudspeaker system with a tweeter 5a, a mid-range driver 5b and a woofer 5c.
  • this three-way loudspeaker system is embodied in a type of cartridge and inserted into the housing 2 from the upper end face of the housing 2.
  • the speaker system 5 also has the usual components, such as a crossover 5d and corresponding cable feeds.
  • the tweeter or tweeter speaker 5a is covered by a spherical or dome-shaped cover 6, so that on the one hand there is a smooth surface for the columnar speaker box 1 and on the other hand injuries when bumping into the speaker box 1 by the rounded design is largely excluded.
  • this elevated, free-standing arrangement of the tweeters 5a offers the possibility that the loudspeaker box 1 radiates all around, as is indicated in FIG. 1 by the circles which appear in perspective and appear as ellipses. This results in an optimal sound system for a person lying or sitting in the bed.
  • lights 14 can also be placed in the housing 2 of the respective loudspeaker box 1 be integrated so that you can read in addition to listening to music.
  • a screen 15 shown in dashed lines for television or video operation can be arranged on a similarly designed central column 10 '.
  • the sound for this is transmitted for the highest possible quality of transmission and sound through the loudspeaker boxes 1 in hi-fi stereo quality designed as bed corner posts.
  • the housing 2 is preferably designed as a perforated plate 11, preferably made of chromium-nickel steel, so that the required load-bearing capacity of the housing 2 results.
  • the perforated plate 11 is supported on a lower base 8, a sound opening 9 for the low-frequency loudspeaker 5c preferably being formed between the perforated plate 11 and the base 8.
  • a sectional view through the housing 2 of the loudspeaker box 1 is shown, the elevated arrangement of the tweeter 5a and the mid-range driver 5b also being shown.
  • These two tweeters and mid-range speakers 5a, 5b are preferably directed towards a double-cone reflector 7, so that there is a largely circular or spherical sound outlet with a soft sound.
  • this is done by means of a screw connection 13 screws from the interior 4 of the housing 2 being able to be inserted through the holes or punched holes in the perforated plate 11, and thus a secure fastening of the furniture part 3, here the backrest part 3b, is achieved.
  • hook-in connections 12 can also be provided, the hooks connected to the furniture part, here the seat part 3c, engaging in the bores or punched holes in the perforated plate 11.
  • the housing 2 can also be designed as a hexagonal or octagonal column.
  • the cartridge-shaped design of the loudspeaker system 5 results in an equally simple assembly when it is being created or, if necessary, when the loudspeaker box 1 is being repaired, since it can be pulled out of the housing 2 in a simple manner without influencing the supporting function of the column.
  • This mounting system can be used in an advantageous manner in addition to the interior in the living area for the assembly of catering furniture, for. B. bar counters, discotheque furniture and the like. Apply.
