Definitions
- the invention relates to a loudspeaker device with at least one loudspeaker and a lighting unit.
- loudspeakers which generally emit the tones in the frontal direction. If there is only one box in the room, the feeling of the spatiality of the sound is missing. In addition, loudspeakers are usually functional, but are often not very attractive. It would be desirable to have a loudspeaker device that fulfills both optical and acoustic requirements, namely a combination of lighting and loudspeaker.
- a problem here, however, is that the loudspeaker requires both a resonance body and a certain amount of sound insulation for optimal sound, whereas uniform lighting, on the other hand, requires a reflector that does not absorb any light, so that the light yield is as high as possible.
- the object of the present invention is therefore to provide a compact loudspeaker device which combines acoustic effects with optical effects, which complement one another.
- the main advantage of the loudspeaker device according to the invention is that the light function is not restricted when the loudspeaker function is optimal, since the loudspeaker and the lighting unit are integrated in a column in such a way that all aspects relating to sound insulation and resonance are fulfilled and, moreover, the desired uniform light guidance to the outer wall of the Pillar and its lighting is thus guaranteed. Furthermore, the listener will have an excellent sound experience mediates, even if only one speaker is placed in the room, since the sound distribution compared to conventional speakers is significantly improved.
- the proposed combination creates a compact loudspeaker device with an integrated lighting unit, which provides a pleasant lighting and sound experience in the living or therapy area or, as an eye-catcher at trade fairs or advertising events, can lead to increased attention, especially when using changing colors over almost the entire range column height.
- 1 a partial longitudinal section of the loudspeaker device; 2: an enlarged longitudinal section according to FIG. 1 with the
- Fig. 3 a plan view of the upper area of the
- FIG. 4 a modified embodiment of the
- the loudspeaker 3 is integrated in a cone-shaped loudspeaker unit 2, which on the one hand serves to soundproof the loudspeaker 3. For this purpose, it is filled with insulating material 22 (cf. FIG. 4) in the amount necessary to optimize the acoustics.
- the loudspeaker unit 2 also serves to reflect a portion of the light from the lighting unit 1 (as indicated by double-dashed lines) onto the wall of a cylindrical, hollow column 5 and takes it in (as indicated by a central wavy line) is) also the supply line or cable routing 4 for the loudspeaker 3.
- the loudspeaker unit 2 is surrounded by a braid 13 which holds the insulating material 22 in position.
- the lighting unit 1 and the loudspeaker unit 2 are thus installed in a compact manner in the column 5, which stands on feet 6, in particular in order to ensure ventilation of the lighting unit 1.
- a tube screen 17 is also used to cover the lighting unit 1 to the outside.
- the lighting unit 1 shows the arrangement of the lighting unit 1 and the cable guide 4 in the lower region of the column 5.
- the lighting unit 1 consists of a radiator 7 which shines through a filter disc 8 arranged above it.
- the latter is rotatably driven by a motor 10, so that different colors (see opposite hatching of two sectors in the top view) are generated within the column 5.
- the supply for the loudspeaker 3 is carried out through the loudspeaker unit 2 via the cable guide 4. This is located in the center, above the radiator 7, in order to avoid shadows. A loosely hanging cable would cast shadows, which would have a negative effect on the overall optical impression.
- the cable guide 4 is fixed to the base of the column 5 by means of a holder 11, as a result of which the lower tip of the loudspeaker unit 2 is centered relative to the radiator 7, namely exactly in the center above it.
- the light rays indicated only in the left half in FIG. 1 for the sake of clarity are hardly disturbed on the way to the wall of the column 5. If a partial beam (as indicated for the lowest beam by the emitter 7) is reflected on the inner wall, this is reflected back by the pointed cone shape on the wall of the column 5, in order to then shine through and a uniform lighting effect over almost the entire height of the Column 5.
- the top view in FIG. 3 illustrates the arrangement of the loudspeaker 3 on the top of the column 5.
- the loudspeaker 3 is by means of fasteners 12, z. B. screws or brackets, fixed on the top of a ring 18.
- the fasteners 14, e.g. B. screws or brackets are used to attach the braid 13 or the rods 21 (see FIG. 4) to the top of the column 5 also on the ring 18 so that the entire unit 2 can be used in the column 5 ,
- the loudspeaker device can be opened if necessary, so that, for example, the loudspeaker unit 2 can be exchanged or the inner wall of the column 5 can be cleaned.
- FIG. 4 shows an alternative embodiment of the cone-shaped loudspeaker unit 2 from FIG. 1.
- the modified loudspeaker unit 2 also consists of a loudspeaker 3 which is integrated in a pointed-cone-shaped unit which carries the insulating material 22 (indicated by dotted lines) necessary for sound insulation.
- the insulation material 22 is not fixed by means of a braid 13, but by means of individual rods 21 which are arranged in a conical shape.
- the advantage of this embodiment is that by using these rods 21, possibly with additional cross struts, the pointed cone shape can be maintained exactly and the insulating material 22 for soundproofing the loudspeaker 3 and possibly light distribution from the radiator 7 to the wall of the column 5 evenly is bounded and fixed.
- the pointed cone-like shape of the loudspeaker unit 2 has the advantage that, with an appropriate choice (preferably white) of the insulating material 22, the light intensity decreases only slightly with increasing distance from the radiator 7, so that the viewer sees the illumination of the column 5 uniformly over its total height , Nevertheless, when using this cone-shaped loudspeaker unit 2, it is not necessary to do without the sound insulation of the loudspeaker 3. So the acoustic possibilities of the loudspeaker 3 are used optimally. Any insulating material that is suitable for isolating sound can be used as insulation material. It is preferred to use material that hardly absorbs light, but on the contrary reflects it as completely as possible. Another possibility is to cover the insulating material 22 with a light or white fleece, so as to minimize the light absorption of the insulation material.
- the height of the cone-shaped loudspeaker unit 2 can vary, depending on the one hand on the overall height of the loudspeaker device, on the other hand on the wishes of the user and also the performance of the loudspeaker 3. However, it is preferred that the height of the loudspeaker unit 2 is approximately three quarters of the Total height of the speaker device is. Although lower heights are also conceivable, the associated volume reduction of the insulating material 22 and thus the sound absorption volume from a certain minimum size brings on acoustic problems.
- the tip angle of the loudspeaker unit 2 is selected such that the top sub-beam indicated in FIG. 1 is not obstructed by the radiator 7 or forms an enveloping tangent to the circumference of the insulating material 22.
- the loudspeaker unit 2 is preferably inserted into the column 5 with the ring 18 hanging from above via the lighting unit 1 below.
- the loudspeaker unit 2 is thus integrated in the preferably cylindrical column 5, although other forms of the hollow column 5, e.g. B. hexagonal column cross sections can be used. Since the column 5 also serves as a resonance body and the acoustics of the loudspeaker device can be optimized as a result, circular hollow cross sections of the column 5 are preferred, especially since this also achieves uniform light radiation on the column wall.
- the holder for the insulating material 22, be it the braid 13 or the rods 21, can be made of different materials consist. Metals or plastics, in particular light-colored, are preferred in order to keep the light absorption as low as possible.
- the preferred number of rods 21 is eight, although any other number would be conceivable, provided it is sufficient to hold the insulating material 22 securely in place and in the cone shape.
- the braid 13 used in FIG. 1 should have a sufficiently small mesh size for securely fixing the insulating material 22, e.g. B. an average mesh size of about 1 to 3 cm or smaller.
- a textile fabric which has sufficient strength to fix the insulating material 22 around the loudspeaker 3 and to hold the cone-shaped loudspeaker unit 2 in its centrally arranged position centrally above the radiator 7 can also be used as the braid 13. This centering is supported by the cable guide 4, in particular if a thin tube is preferably used for this, preferably made of heat-resistant plastic.
- a tube made of acrylic glass is preferably used, although any other translucent material, such as. B. sandblasted glass, can be used equally.
- the opacity and color of the material of the hollow column 5 can be varied as required by the customer, but a certain opacity is expedient in order to cover the inner parts of the column 5, namely in particular the loudspeaker unit 2 and the lower lighting unit 1 for optical reasons. Further optical effects can be achieved with hollow glass columns, some of which have graphic elements with a different opacity than the rest.
- a base is provided with which the functions of both the lighting unit 1 can be operated remotely, in particular the rotational speed of the filter disk 8 by controlling the motor 10 and / or the light intensity of the spotlight 7 (dimmer function).
- a color filter disk with a plurality of colors is preferred as the filter disk 8 (cf. different hatching of the eight sectors in FIG. 2, for example) in order to produce changing colors on the wall of the column 5 in rapid or slow succession and thus special optical effects.
- the feet 6 on the underside of the column 5 are advantageous. They can be made of different materials (e.g. wood, metal, plastic, stone, etc.) and have different shapes (cylindrical, conical, hemispherical, pyramidal, etc.). It is also possible to integrate several loudspeakers 3 into the column 5. These can be arranged both in the upper area and in the base, for. B. an additional bass speaker in the foot of column 5.
