Definitions

  • the invention relates to a speaker housing, comprising a bottom and a lid, with bottom and lid over intermediate, substantially flat Baffles with shop windows are interconnected and interconnected and located in the Inside the housing are several speakers of different characteristics
  • the present invention is concerned with such an arrangement of the individual Speaker of a system to realize, so that the case different Application purposes and installation ideas is fair.
  • baffles in cross-sectional view form an isosceles triangle; the forward facing larger baffle the so-called front or rear center is assigned, the two equal sized baffles depending on the mounting location of the left Front channel (right rear channel) and the right front channel (left rear channel) are assigned, and that means for attaching the housing to a wall or a tripod in the rear part of the housing are provided.
  • FIG. 1 shows a loudspeaker housing. It essentially has the form of a Trapezoid with a substantially flat lid 13 and a corresponding 14.
  • Floor and cover have the shape of a isosceles triangle. Bottom and lid can also be forward diverge.
  • the distances between the floor and the lid are determined by intermediate walls, the are essentially flat and with sound holes or sound windows are formed.
  • the front baffle 10 is with the relatively large front sound openings educated. Behind this baffle 10 are the speakers, depending on Arrangement with rear center or front center to be called.
  • the smaller baffles 11 and 12 are formed with corresponding sound windows and they are the right rear channel and the left front channel on the one hand and the right front channel and the left rear channel assigned, reflecting the nature of the arrangement depends in the room. These relationships can be seen by the view of Figure 2.
  • Figure 3 shows an alternative type of wall suspension with a single Speaker enclosure. An arrangement with two such housings is conceivable, wherein then the second system is replaced in the direction of the figure 3 forward.
  • the housing is outward at the three triangular corners with the help of aluminum profiles rounded, these profiles are attached to the baffles 10, 11 and 12.
  • the aluminum profile is designed so that there is the electrical Connections can be made and also fasteners be available. It's meant to be fixed with a tripod, as well good is also an attachment to a wall possible.
  • three separate audio channels can be combined in one housing are the left and the right and the center channel, all three channels of separate amplifiers with different signals can be controlled. Of the one channel radiates directly, while the other two are indirect radiators. The sound The left and right channels are aimed at large reflectors such as room walls and reaches the listener primarily as reflected indirect sound.
  • phase of the reversed low-midrange sounder is also rotated by up to 180 ° with the help of inductors and capacitors. Below 400 Hz there is therefore almost equal phase between the different polarized woofers, while above 400 Hz there is a phase difference of up to 180 °.
