Definitions

  • the invention relates to an arrangement of speakers, consisting of at least one bass speaker, mid-range speaker and tweeter.
  • Loudspeakers are known in which the bass, mid-range and tweeters are arranged in the front of the housing of the loudspeaker, which loudspeakers are connected via switches.
  • the disadvantage of these loudspeakers is that they do not allow distortion-free transmission in rooms, since the respective room designs are different and cause complicated reflection and absorption conditions.
  • Another disadvantage of known loudspeaker boxes is that they represent a rigid system that does not open up any possibilities for further changes.
  • the individual speakers are usually connected to each other by a crossover, which is arranged in the speaker cabinet.
  • the disadvantage here is that the interior of the loudspeaker box is thermally stressed and the loudspeakers can be influenced by electromagnetic waves.
  • the static deflection in loudspeaker cabinets with a center of gravity lying high on the base surface leads to nicking of the loudspeaker cabinet. These vibrations can lead to tilting movements of the loudspeaker box, which also affect the sound image due to mechanical noises.
  • the forces occurring on a loudspeaker box are essentially the opening forces of the membranes, in particular the membranes of the bass loudspeakers. The main component of these forces acts along the horizontal. As soon as - depending on the material properties of the loudspeaker cabinet and the surface - the static friction has been overcome in the area of the superimposed surfaces, only a reduced horizontal force is required to overcome the sliding friction and to move the loudspeaker box.
  • the object of the invention is to provide an arrangement of the type mentioned, by means of which a spatial alignment of loudspeakers with loudspeakers in the bass, mid-range and high-frequency range can be carried out in a simple manner so that the respective interior design and the requirements of the operator of the hi-fi system are taken into account, whereby horizontally acting undesirable vibrations of the loudspeaker cabinet housings caused by vibrations of the membrane are not to be transmitted to their subsurface and thermal and / or electromagnetic influences on the loudspeakers are to be prevented.
  • each loudspeaker is arranged in an independent housing, that the housings are designed to be stackable one on top of the other, an interchangeable magnetically shielded crossover network being arranged on one of the housings or at a distance therefrom, which crosses with the loudspeakers can be connected to the stacking housing, and that devices for vibration-damping mounting of the respective loudspeaker box are arranged on the base plate of each housing.
  • the arrangement according to the invention makes it possible in modular system technology to create loudspeaker systems which are adapted to different music styles. If the requirements of the operator of the hi-fi system change or increase, it is only necessary to replace the corresponding loudspeaker modules. An adapted exchange of the crossover must then also be carried out at the same time. This is easy to do because the crossover is placed on a speaker cabinet or even at a distance from it. This prevents the interior of the loudspeaker cabinet from being additionally thermally stressed by the crossover under high loads, and possibly the cooling of the voice coil of the sound transducer being impaired by the increased internal temperature.
  • the arrangement of the crossover outside the loudspeaker cabinet prevents the respective loudspeaker from being influenced by the magnetic fields of the inductance on the crossover or the interference of interference fields into the wiring within the loudspeaker box.
  • the action electro Magnetic waves is prevented according to the invention in that the crossover has a magnetic shield.
  • the crossover module can be easily replaced by the external arrangement of the crossover in order to be able to influence the timbre. It is particularly advantageous that, according to one embodiment of the invention, the loudspeaker box housings can be stored so smoothly that only rolling friction occurs, so that a corresponding damping of the power transmission into the ground occurs.
  • a concavely curved bearing pan which can roll on a spherical support body.
  • the curvature of the bearing pan achieves progressive movement damping along the taxiway.
  • the speaker only has to exert the force to overcome the rolling friction. This results in a particularly good minimization of vibration emissions through the loudspeaker cabinet.
  • the arrangement of loudspeakers 2 in the embodiment shown in FIGS. 1 to 3 consists of three housings 3, 4, 5, in each of which a loudspeaker 2 is arranged.
  • a bass speaker 7 as the loudspeaker 2
  • a mid-range speaker 8 in the housing 4 as loudspeaker 2
  • a tweeter loudspeaker 9 in the housing 5 as loudspeaker 2.
  • a crossover 6 is arranged on the outer wall of the housing 3, to which the Bass speaker 7, the mid-range speaker 8 and the tweeter 9 are each connected with a cable 14. It is also possible to arrange the crossover 6 at a distance from the housings 3, 4, 5.
  • the housings 3, 4, 5 designed as modules with loudspeakers 2 can be arranged in such a way that radiation in the correct phase is achieved. Furthermore, it is possible to specifically align the housing 4 with the mid-range loudspeaker 8 and the housing 5 with the tweeter loudspeaker 9 to the listening position, while the bass loudspeaker 7 is oriented in the housing 3 in a basic position. An example of such a displacement of the housings 4, 5 relative to the housing 3 is shown in FIG. 3.
  • each housing 3, 4, 5 On the lower side 11 of each housing 3, 4, 5 are knob-like support feet 12 made of a non-slip material, such as e.g. Rubber, arranged ( Figure 4a and Figure 4b).
  • the support feet prevent that stacked housings 3, 4, 5 change their position with a slight touch.
  • an amplifier 13 is provided which is connected to the bass loudspeaker 7, mid-range loudspeaker 8 and cooking tone loudspeaker 9.
  • the amplifier 13 can be connected to the loudspeaker arrangement 10 by means of a connecting cable or can also be designed as a module so that it can be integrated into the loudspeaker arrangement 10. An example is shown schematically in FIG. 5.
  • the walls of the housings 3, 4, 5 preferably consist of a medium-density fiberboard, which enables precise, deep bass reproduction. In addition, this fiberboard is easy to work without the risk of material breakouts.
  • box feet 31, 32, 33, 20 are described, which enable a vibration-damping mounting of a housing 3 or 4 or 5 of a loudspeaker box 36.
  • the box foot 31 consists of a shell-shaped housing 41 which is open on one side and in which a vibration-damping material 35 is arranged.
  • This material consists of two layers.
  • the lower layer is designed as an elastic plate 41 made of rubber or the like.
  • a soft foam layer 40 is arranged on this.
  • a ball 39 is embedded in the soft foam layer 40 as a supporting body 38, on which the base plate 37 of a loudspeaker box 36 can be mounted. Vibrations occurring in the loudspeaker box 36 are absorbed by the vibration-damping material 35 and are not transmitted to the surface on which the box foot 31 is arranged (FIG. 6).
  • Fig. 7 another box foot 32 is Darge provides, in which a liquid 43 is selected as the vibration-damping material 35.
  • a liquid 43 is selected as the vibration-damping material 35.
  • an elastic plate 41 designed as a floating body, which is sealed at the edge against the housing 34 by means of seals 42.
  • the elastic plate 41 protrudes from the side wall of the housing 34 and serves as a support body 38 for the loudspeaker box 36.
  • FIG. 8 shows a box foot 33 in which a liquid 43 is also provided as the vibration-damping material 35.
  • the liquid 43 is in an envelope 44 made of elastic material, which is arranged in the housing 34.
  • the upper free surface of the casing 44 is designed as a support surface 45 for the base plate 37 of a loudspeaker box 36.
  • FIG. 9 shows a particularly advantageous embodiment of a box foot 20 for the vibration-damping mounting of a loudspeaker box 36.
  • a damping ring 19 is located in a housing 34, which is designed as a foot housing and has a recess 26 in the center that is conical in cross section. The opening section of this recess 26 is formed by a circumferential flange 27 which is formed on the damping ring 19. The flange 27 is surrounded by a rigid ring plate 29.
  • the ball 39 and the support plate 25 are preferably made of steel, e.g. V2A steel.
  • a stiffening profile section 22 is formed on the housing 34 and is arranged on the lower edge of the housing 34.
  • the stiffening profile section 22 surrounds a non-slip elastic washer 23, e.g. can consist of a felt.
  • a bearing pan 16 is arranged on the base plate 37 of the housing of the loudspeaker box 36 and has a concave arch piece 17 resting on the ball 39.
  • the edge 30 of the arc piece 17 lies on the ring plate 29.
  • An edge-side holding flange 18 is formed on the bow piece 17 and is connected to the base plate 37 of the housing of the loudspeaker box 36.
  • the connection is preferably made by means of an adhesive connection 21.
  • the described box feet 31, 32, 33, 20 can, depending on the design of the speaker box 36, be used in different numbers as box feet for a speaker box 36 and prevent the vibrations occurring in the speaker box 36 from being transmitted to the ground.
