Definitions

  • This invention relates to a loudspeaker enclosure.
  • Loudspeaker enclosures are available which, instead of the more common rectangular outline, have a trapezoidal shape when viewed from the side.
  • a number of such loudspeaker enclosures can be placed together, with adjacent sides touching, so as to form an arc in an attempt to distribute sound more evenly round a wide area.
  • the trapezoidal shape militates against this.
  • the invention seeks to provide a loudspeaker enclosure improved in the above respects.
  • a loudspeaker enclosure having front and back faces, a pair of opposed side faces generally trapezoidal in outline, and a pair of opposed support faces characterised in that one of the opposed support faces carries an even number of raised ribs and the other of the support faces carries an odd number of raised support ribs.
  • the even and odd numbers are adjacent to one an other, for example four ribs and three ribs.
  • the spacing of the ribs is chosen so that if odd and even faces are brought together then ribs will intermesh and the adjacent faces "nest"; whereas if like faces are brought together the ribs will oppose one another and the adjacent faces will stack.
  • the enclosure is moulded e.g. from a plastics material.
  • the enclosure may be provided with a grill, connections, lifting handles, and the like commonly provided on loudspeaker enclosures.
  • Figure 1 is a perspective rear view of a loudspeaker enclosure in accordance with the invention.
  • Figure 2 is a similar view to Figure 1 of four enclosures in stacking mode.
  • a speaker enclosure generally designated 10 comprises front 12 and rear 14 faces, with the front face 12 being provided with a grill for covering the voice cone of a loudspeaker mounted within the enclosure.
  • Side faces 16 are generally trapezoidal in outline, upper 18 and 20 support faces are provided with ribs as discussed more fully herein after.
  • the upper surface 18 is provided with an even number of ribs 22, in this case 4, with three corresponding depressions 24 therebetween.
  • the lower face 20 is provided with three ribs 26 with four corresponding depressions 28.
  • the ribs 22,26 as shown are essentially wedged shaped and the angle is such so as to compensate for the angle of tapering of the trapezoidal faces 16 so that the upper surfaces of ribs 22 and lower surfaces of ribs 26 respectively are essentially parallel.
  • the enclosure 10 of the invention operates, in the nesting mode, as a traditional trapezoidal speaker and, in the stacking mode, as a traditional rectangular speaker enabling both functions to be carried out with the one design.
  • the upper and lower faces of the ribs 22 may be given an anti-friction surface such as a rubber pad or, indeed, the surfaces may be formed with ribs of a similar configuration in inature to the upper and lower surfaces 18 and 20 to prevent relative sideway slipage when the enclosures are stacked.

Abstract

Enceinte de haut-parleur comprenant des faces avant (12) et arrière (14) ainsi que des faces latérales opposées (16) de contour généralement trapézoïdal. Les faces de support supérieure (18) et inférieure (20) sont dotées de parties saillantes allongées de manière à ce qu'une face de support ait un nombre pair de parties saillantes allongées et l'autre ait un nombre impair de parties saillantes allongées. L'espacement entre lesdites parties saillantes allongées est conçu de telle manière que lorsque des faces identiques sont posées l'une sur l'autre, les parties saillantes se font opposition et les faces s'empilent, et lorsque des faces paires et impaires sont posées l'une sur l'autre, les parties saillante allongées s'engrènent et les faces adjacentes s'emboîtent. Cela permet d'empiler les haut-parleurs en cas d'utilisation ou de transport et cependant de les emboîter, si on le désire, pour produire une forme en arc.
