Abstract

A loudspeaker-lamp combination has at least one loudspeaker (3) with at least one electroacoustic transducer associated to a sound-radiating reflector body (4), and at least one lamp with a light source. In order to achieve a simple design that uniformly radiates both sound and light, the light source (5) is arranged in the area of the conical reflector body (4) whose outer reflector surface (4a, 4b) reflects and radiates both acoustic waves and light beams over a large surface.

Description

Speaker-lamp combination Description

The invention relates to a loudspeaker-luminaire combination comprising at least one loudspeaker with at least one electroacoustic transducer, to which a reflector body for sound radiation is assigned, and at least one luminaire with a light source.

Such speakers with reflectors are known for example from DE-GM 87 00 649 and DE-GM 92 05 731. Such a construction with a conical reflector body is used primarily because the radiation characteristic bundles with increasing frequency, so that conventional electroacoustic transducers can be located relatively precisely in the high frequency range. In order to cover such punctiform sound sources, these diffusion or reflection cones are used so that the all-round sound radiation is modeled on the actual sound behavior and thus high-quality music reproduction is achieved.

However, these loudspeakers only serve to emit sound waves, even if in the discotheque area these loudspeakers in column form are often provided with a position light in order to avoid visitors bumping into the loudspeaker box and to achieve a certain orientation. However, these lights, which can also be used as light organs, are often only arranged on the outer circumference of the loudspeaker housing as separate point light sources, so that no uniform lighting is to be expected therefrom, except that a large number of such point lights would be provided. However, this would increase the construction and cabling work considerably.

Furthermore, from DE-GM 76 00 002 a speaker-light combination is known, in which a speaker box is arranged within a cylindrical lampshade. The sound radiation is directed through the open upper and lower end faces of the lampshade, so that none All-round sound radiation and no light distribution is possible. The same applies to the combined light and sound source according to DE-OS 30 23 891, in which an annular reflector is provided to cover disturbing background noise, such as speech and machine noise at office workplaces. The sound radiation is bundled against a building ceiling in order to shield the respective office room elements in a large office from ambient noise. From DE-GM 70 16 648 is finally one

External speaker unit is known, which is provided with ring-like slats for weather protection of a centrally arranged speaker and / or light. However, it is also not possible to improve the sound and immediately the light radiation and all-round distribution from a compact housing.

Accordingly, the object of the invention is to create a loudspeaker-luminaire combination with which both a uniform sound radiation and a uniform light radiation are achieved with a simple construction.

This object is achieved by a loudspeaker-luminaire combination in accordance with the features of patent claim 1.

By arranging the light source in the vicinity of the reflector body, it can be used in a particularly advantageous manner both for deflecting the sound waves in the sense of all-round sound radiation and also for deflecting the light beams to generate a wide-area, uniform light. The reflector body thus fulfills a double purpose with its reflector surface (s), namely a deflection of both the sound waves and the light beams. In the preferred embodiment of the reflector body as a downward cone or cone, light emission and sound emission, for example at head height, are thus achieved with a compact arrangement of the components. By appropriate choice of the cone angle of the reflector body, however, one can particularly simple lighting in the manner of a floodlight can be achieved. For this purpose, the reflector body is preferably designed as an asymmetrical cone or cone, the flatter conical surface serving to deflect the sound, while the steeper conical surface serves to deflect the light upwards towards the ceiling. Instead of the asymmetrical arrangement, the light source and the electroacoustic transducer (eg dome loudspeaker) can also be arranged offset with respect to the central axis of the reflector body, so that different radiation angles also result. Due to the relative offset of the reflector body, the radiation angle for both the sound waves and the light beams can be changed by moving or rotating the reflector body, so that simple variations in the sound and light radiation can be achieved to produce a tremolo effect or a light organ effect .

In a preferred embodiment, a color filter disk in a circular ring shape is arranged around the upward-facing loudspeaker with a reflector body above it, which has different colors or patterns, so that the light color can be adapted to the respective music by turning this filter ring in a manual or motorized manner. In serious music, for example, this color filter ring can be used to create a rather cool mood by setting a blue color, while in pop or rock music, using louder colors such as yellow or orange, a corresponding adjustment to the rhythm can be made optically. In the case of a motorized drive, this color ring can also be rotated according to the rhythm or volume in the manner of a light organ, so that there are many possibilities for adaptation. The simple construction is particularly noteworthy, and in addition, in the housing of the loudspeaker-light combination, music devices such as radio, CD player, cassette recorder and the like can be accommodated in a compact manner in a confined space. Thus, a multi-purpose device is created that in the manner of a Wall lamp, table lamp or floor lamp in the discotheque, bar, but also in the living area can be used, the basic body in modular design being essentially the same, and can be supplemented by a high or low base.

Further advantageous embodiments are the subject of the dependent claims.

Several exemplary embodiments are described and explained in more detail below with reference to the drawings. Show here:

Fig. 1 is a speaker-lamp combination in the manner of a

Wall lamp; Fig. 2 is a speaker-lamp combination in the manner of a

Table lamp; Fig. 3 is a speaker-lamp combination in the manner of a

Floor lamp; and FIG. 4 shows the use of two such speaker-light combinations in connection with a television set or a bar counter. In Fig. 1, a speaker-lamp combination 1 is shown in the design of a wall lamp, the quarter-spherical housing 2 is attached to a wall in the usual way. On the flat top of the housing 2, a loudspeaker 3 is inserted with the sound opening pointing upwards. This loudspeaker 3 radiates onto a reflector body 4, the outer reflector surface 4a of which deflects the sound waves indicated by dashed lines approximately in the horizontal plane. The attached reflector body 4 in this case represents about half of a torus body in the manner of a cone or a cone. However, the reflector body 4 can also be pyramid-shaped or polygon-shaped, with the tip of this reflector body 4 essentially pointing down towards the loudspeaker 3 .

Furthermore, there is at least one light source 5 in the housing 2, for example as a halogen lamp on the outer circumference of the Loudspeaker 3 arranged. This light source 5 also emits onto the outer reflector surface 4a of the reflector body 4, the light beams, indicated by the two-dot-dash lines, striking the flatter region of the reflector surface due to the offset relative to the loudspeaker 3, and therefore have a different radiation angle with respect to the sound waves. It is essential here, however, that the deflection of both the sound waves and the light beams and thus their distribution and deflection is carried out by the single reflector body 4. For this purpose, the reflector surface 4a is preferably metallized or chromed, so that the highest possible degree of reflection results.

In this case, a color filter is preferably arranged as a filter disk 6 above the light source 5 and can be designed to be interchangeable in order to thereby produce different colors. However, the filter disk 6 is preferably designed as a circular ring 6a around the loudspeaker 3, so that this circular ring 6a can be rotated about the central axis by means of a knurled disk 7. A large number of differently colored filter disks 6 are provided on the circular ring 6a so that any color tones can be produced, depending on the type of music being played. The music is preferably reproduced by an electronic music device 10, also integrated in the housing 2, for example in the form of a radio or a cassette recorder. This music device 10 can be operated by buttons 11 on the outside of the housing 2. An electronic component 12 in the form of a light organ circuit is preferably assigned to the music device 10, so that the filter circular ring 6a can thereby be driven in accordance with the prevailing music and rotated via drive circuits (not shown), for which purpose an adjusting motor 8 (cf. Fig. 2) is provided. However, a plurality of light sources 5 can also be provided on the outside around the loudspeaker 3, which light sources 5 are then correspondingly controlled by the light organ circuit 12. In addition or alternatively to the light source 5 in the lower housing 2, as shown in FIG. 2, a light source 5 ^* "can also be arranged in the interior of the preferably hollow or funnel-shaped reflector body 4, which emits onto the inner reflector surface 4b and thus in It should be noted that in the manufacture of the reflector body 4 and coating of the outer reflector surface 4a, the inner surface 4b can also be produced very simply, and thus the reflector body 4 as the only component in double use of the deflection the sound waves as well as the light rays.

2 shows an embodiment as a table-speaker-light combination, the reflector body 4 being designed as an asymmetrical cone. By adjusting the rotational position about the upright axis 4c of the reflector body 4, the type and preferred direction of the all-round radiation both for the light rays and the sound waves can be changed as desired by the listener. The adjustment axis 4c is rotatable on a light and sound-permeable cover 9, for. B. stored a coarse mesh metal fabric. The rotation of the reflector body 4 about the axis 4 c can be done manually or by a motor, similar to the adjustment motor 8. Furthermore, the adjusting motor 8 is also shown for driving the color filter circular ring 6a, so that a color change can take place in accordance with the volume or clock frequency of the music emitted by the loudspeaker 3. Otherwise, the structure corresponds essentially to the embodiment according to FIG. 1, wherein the housing 2 can also be designed as a hemisphere or polygon instead of cylindrical.

3 shows an embodiment of the loudspeaker-light combination in the manner of a free-standing light, with further components such as a clock below the loudspeaker 3 and a fan 15 being installed above the upper light source 5 '. This fan 15 can be used, for example, for room air conditioning, but also for accelerated evaporation and distribution of fragrance oils, which are filled in a shell 13, for example, in the upper reflector cover 14. Furthermore, a color variation possibility similar to that of the filter circular ring 6a is also shown on the upper light source 5 'and is designated 6a' for distinction. Thus, alternatively or in addition to the above embodiment, the color tone of the light rays emitted upwards towards the ceiling can also be varied. The height can be varied by means of an adjustable guide tube 16, and additional components can also be installed in the base 17.

Finally, FIG. 4 shows the use of the loudspeaker-light combination 1 in a double design to achieve a stereo effect in connection with a television set 20 or a hi-fi system (not shown in more detail). In this case, there is also a further loudspeaker 3 ', e.g. a woofer is provided without additional lighting. The structure otherwise corresponds essentially to the columnar design according to FIG. 2, wherein the orientation of the sound and light on the viewer can be adjusted, for example, by remote control of the television set 20 by changing the rotational position of the asymmetrical reflector body 4. The user thus has a multitude of possible variations with regard to more direct or more indirect sound or light radiation with all intermediate stages. Here, the preferred use is also shown in a bar counter 18, the two (or more) loudspeaker-lamp combinations 1 being fastened to a holder 19 which also serves as a bottle shelf.
