Beleuchtete LautsprechervorrichtungIlluminated speaker device
Die Erfindung bezieht sich auf eine Lautsprechervorrichtung mit zumindest einem Lautsprecher und einer Beleuchtungseinheit.The invention relates to a loudspeaker device with at least one loudspeaker and a lighting unit.
Üblicher Stand der Technik sind Lautsprecherboxen, welche die Töne im allgemeinen in frontaler Richtung abstrahlen. Ist nur eine Box im Raum vorhanden, so fehlt das Gefühl der Räumlichkeit des Klanges. Außerdem sind Lautsprecherboxen zwar in der Regel funktional, aber oft optisch wenig ansprechend. Wünschenswert wäre eine Lautsprechervorrichtung, die optische und akustische Ansprüche gleichermaßen erfüllt, nämlich eine Kombination aus Beleuchtung und Lautsprecher. Ein Problem hierbei ist jedoch, daß der Lautsprecher für eine optimale Klangfülle sowohl einen Resonanzkörper als auch eine gewisse Schalldämmung erfordert, während eine gleichmäßige Beleuchtung dagegen einen Reflektor verlangt, der möglichst kein Licht absorbiert, damit die Lichtausbeute möglichst hoch ist.The usual state of the art are 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.
Aufgabe der vorliegenden Erfindung ist es deshalb, eine kompakt bauende Lautsprechervorrichtung zur Verfügung zu stellen, die akustische Effekte mit optischen verbindet, wobei sich diese gegenseitig ergänzen.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.
Diese Aufgabe wird gelöst durch eine Lautsprechervorrichtung gemäß Anspruch 1. Vorteilhafte Ausbildungen sind Gegenstand der Unteransprüche.This object is achieved by a loudspeaker device according to claim 1. Advantageous developments are the subject of the dependent claims.
Der Hauptvorteil der erfindungsgemäßen Lautsprechervorrichtung ist, daß bei optimaler Lautsprecherfunktion die Lichtfunktion nicht eingeschränkt wird, da der Lautsprecher und die Beleuchtungseinheit so in einer Säule integriert sind, daß alle Aspekte hinsichtlich der Schalldämmung und Resonanz erfüllt sind und zudem die gewünschte gleichmäßige Lichtführung an die Außenwand der Säule und deren Beleuchtung damit gewährleistet ist. Ferner wird dem Hörer ein ausgezeichnetes Klangerlebnis vermittelt, auch wenn nur ein Lautsprecher im Raum plaziert ist, da die Klangverteilung gegenüber herkömmlichen Lautsprechern deutlich verbessert wird. Insbesondere wird durch die vorgeschlagene Kombination eine kompakte Lautsprechervorrichtung mit integrierter Beleuchtungseinheit geschaffen, die im Wohnoder Therapiebereich für ein angenehmes Licht- und Klangerlebnis sorgt bzw. als Blickfang auf Messen oder Werbeveranstaltungen zu einer erhöhten Aufmerksamkeit führen kann, insbesondere bei Einsatz wechselnder Farben über nahezu die gesamte Säulenhöhe.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. In particular, 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.
Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnungen näher beschrieben. Es zeigen:An embodiment of the invention is described below with reference to the drawings. Show it:

Lautsprechereinheit in perspektivischer Darstellung.Loudspeaker unit in perspective.
In Fig. 1 ist eine säulenförmige Lautsprechervorrichtung mit einer untenliegenden Beleuchtungseinheit 1 und einem oberen Lautsprecher 3 dargestellt. Der Lautsprecher 3 ist in eine spitzkegelförmige Lautsprechereinheit 2 integriert, die zum einen der Schalldämmung des Lautsprechers 3 dient. Hierfür ist sie mit Isoliermaterial 22 (vgl. Fig. 4) in der zur Optimierung der Akustik notwendigen Menge gefüllt. Zum anderen dient die Lautsprechereinheit 2 aufgrund der Spitzkegelform auch zur Lichtreflektion eines Lichtanteils von der Beleuchtungseinheit 1 ( wie dies mit doppelt strichpunktierten Linien angedeutet ist) auf die Wandung einer hier zylindrischen, hohlen Säule 5 und nimmt in sich ( wie dies mit einer zentralen Wellenlinie angedeutet ist) außerdem die Zuleitung bzw. Kabelführung 4 für den Lautsprecher 3 auf . Die Lautsprechereinheit 2 ist umgeben von einem Geflecht 13, welches das Isoliermaterial 22 in Position hält. Die Beleuchtungseinheit 1 und die Lautsprechereinheit 2 sind somit in kompakter Weise in die Säule 5 eingebaut, die auf Füßen 6 steht, insbesondere um eine Belüftung der Beleuchtungseinheit 1 zu gewährleisten. Im unteren Bereich der bevorzugt aus einem Acrylglasrohr bestehenden Säule 5 ist zudem eine Rohrblende 17 eingesetzt, um die Beleuchtungseinheit 1 nach außen hin abzudecken.1 shows a columnar loudspeaker device with a lighting unit 1 underneath and an upper loudspeaker 3. 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. On the other hand, due to the pointed cone shape, 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. In the lower area of the column 5, which is preferably made of an acrylic glass tube, a tube screen 17 is also used to cover the lighting unit 1 to the outside.
Fig. 2 zeigt die Anordnung der Beleuchtungseinheit 1 und der Kabelführung 4 im unteren Bereich der Säule 5. Die Beleuchtungseinheit 1 besteht aus einem Strahler 7 , welcher eine darüber angeordnete Filterscheibe 8 durchstrahlt. Letztere wird mittels eines Motors 10 drehbar angetrieben, so daß unterschiedliche Farben (vgl. entgegengesetzte Schraffur von zwei Sektoren in der Draufsicht) innerhalb der Säule 5 erzeugt werden. Die Zuleitung für den Lautsprecher 3 erfolgt durch die Lautsprechereinheit 2 hindurch über die Kabelführung 4. Diese befindet sich, um Schatten zu vermeiden, unmittelbar mittig über dem Strahler 7. Ein lose herabhängendes Kabel würde Schatten werfen, was den optischen Gesamteindruck negativ beeinflussen würde. Die Kabelführung 4 ist mittels einer Halterung 11 am Boden der Säule 5 fixiert, wodurch auch die untere Spitze der Lautsprechereinheit 2 relativ zum Strahler 7, nämlich exakt mittig über diesem zentriert ist. Dadurch werden die in Fig. 1 aus Gründen der Übersichtlichkeit nur in der linken Hälfte angedeuteten Lichtstrahlen auf dem Weg zur Wandung der Säule 5 kaum gestört. Wenn ein Teilstrahl (wie für den untersten Strahl von dem Strahler 7 angedeutet) an der Innenwandung reflektiert wird, wird dieser durch die Spitzkegelform wieder auf die Wandung der Säule 5 zurückreflektiert, um diese dann zu durchstrahlen und einen gleichmäßigen Leuchteffekt über nahezu die gesamte Höhe der Säule 5 zu ergeben.2 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. As a result, 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.
Die Draufsicht in Fig. 3 verdeutlicht die Anordnung des Lautsprechers 3 an der Oberseite der Säule 5. Der Lautsprecher 3 wird mittels Befestigungen 12, z. B. Schrauben oder Klammern, auf der Oberseite eines Rings 18 fixiert. Die Befestigungen 14, z. B. Schrauben oder Klammern, dienen dazu, das Geflecht 13 oder die Stäbe 21 (vgl. Fig. 4) an der Oberseite der Säule 5 ebenfalls an dem Ring 18 zu befestigen, so daß die gesamte Einheit 2 in die Säule 5 eingesetzt werden kann. Durch Lösen des Ringes 18 kann die Lautsprechervorrichtung im Bedarfsfalle geöffnet werden, so daß beispielsweise die Lautsprechereinheit 2 ausgetauscht oder die Innenwandung der Säule 5 gereinigt werden kann.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 , By loosening the ring 18, 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.
In Fig. 4 ist eine alternative Ausführungsform der spitzkegelförmigen Lautsprechereinheit 2 von Fig. 1 dargestellt. Die abgewandelte Lautsprechereinheit 2 besteht ebenfalls aus einem Lautsprecher 3 , welcher in eine spitzkegelförmige Einheit integriert ist, die das zur Schalldämmung notwendige Isoliermaterial 22 ( punktiert angedeutet) trägt. Die Fixierung des Isoliermaterials 22 erfolgt im Unterschied zu Fig. 1 jedoch nicht mittels eines Geflechtes 13, sondern mittels einzelner Stäben 21, welche spitzkegelförmig angeordnet sind. Der Vorteil dieser Ausführungsform ist, daß durch die Verwendung dieser Stäbe 21, ggf. mit zusätzlichen Querstreben, die Spitzkegelform exakt eingehalten werden kann und das Isoliermaterial 22 zur Schalldämmung des Lautsprechers 3 und ggf. Lichtverteilung von dem Strahler 7 zur Wandung der Säule 5 hin gleichmäßig umgrenzt und fixiert wird.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. In contrast to FIG. 1, 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.
Die spitzkegelartige Form der Lautsprechereinheit 2 bringt den Vorteil mit sich, daß bei entsprechender Wahl (bevorzugt weiß) des Isoliermaterials 22 die Lichtstärke mit zunehmender Entfernung von dem Strahler 7 nur geringfügig abnimmt, so daß dem Betrachter die Ausleuchtung der Säule 5 über deren Gesamthöhe gleichmäßig erscheint. Trotzdem braucht bei Verwendung dieser spitzkegelförmigen Lautsprechereinheit 2 auf die Schalldämmung des Lautsprechers 3 nicht verzichtet werden. So werden die akustischen Möglichkeiten des Lautsprechers 3 optimal genützt. Als Dämmungsmaterial kann jedes Isoliermaterial verwendet werden, welches dazu geeignet ist, Schall zu isolieren. Bevorzugt wird solches Material eingesetzt, das kaum Licht absorbiert, sondern im Gegenteil dieses möglichst vollständig reflektiert. Eine andere Möglichkeit ist, das Isoliermaterial 22 mit einem hellen oder weißen Vlies zu umhüllen, um so die Lichtabsorption des Dämmungsmaterials zu minimieren.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.
Die Höhe der spitzkegelförmigen Lautsprechereinheit 2 kann variieren, in Abhängigkeit zum einen von der Gesamthöhe der Lautsprechervorrichtung, zum anderen von den Wünschen des Anwenders bzw. auch der Leistung des Lautsprechers 3. Es wird jedoch bevorzugt, daß die Höhe der Lautsprechereinheit 2 etwa drei Viertel der Gesamthöhe der Lautsprechervorrichtung beträgt. Zwar sind auch geringere Höhen denkbar, allerdings bringt die damit einhergehende Volumenreduzierung des Isoliermaterials 22 und damit des Schallschluckvolumens ab einer gewissen Minimalgröße Akustikprobleme mit sich. Der Spitzenwinkel der Lautsprechereinheit 2 ist dabei so gewählt, das der in Fig. 1 angedeutete oberste Teilstrahl von dem Strahler 7 nicht behindert wird bzw. dieser eine umhüllende Tangente an der Umfang des Isoliermaterials 22 bildet.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.
Wie oben angesprochen, ist die Lautsprechereinheit 2 bevorzugt mit dem Ring 18 von oben her hängend über die untenliegende Beleuchtungseinheit 1 in die Säule 5 eingesetzt. Die Lautsprechereinheit 2 ist somit in die bevorzugt zylinderförmig gestaltete Säule 5 integriert, obgleich auch andere Formen der hohlen Säule 5, z. B. hexagonale Säulenquerschnitte verwendbar sind. Da die Säule 5 zugleich als Resonanzkörper dient und dadurch die Akustik der Lautsprechervorrichtung optimiert werden kann, werden kreisförmige Hohlquerschnitte der Säule 5 bevorzugt, zumal hierdurch auch eine gleichmäßige Lichtabstrahlung an der Säulenwandung erzielt wird.As mentioned above, 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.
Die Halterung für das Isoliermaterial 22, sei es das Geflecht 13 oder die Stäbe 21, können aus verschiedenen Materialien bestehen. Bevorzugt werden Metalle oder Kunststoffe, insbesondere hellfarbig, um die Lichtabsorption möglichst gering zu halten. Die bevorzugt verwendetete Anzahl der Stäbe 21 beträgt acht, obgleich jede andere Anzahl denkbar wäre, sofern sie ausreichend ist, das Isoliermaterial 22 sicher in Position und in der Spitzkegelforn zu halten. Das in Fig. 1 verwendete Geflecht 13 sollte eine ausreichend geringe Maschengröße zur sicheren Fixierung des Isoliermaterials 22 haben, z. B. eine durchschnittliche Maschengröße von ca. 1 bis 3 cm oder kleiner. Verwendbar als Geflecht 13 ist auch ein textiles Gewebe, das eine ausreichende Festigkeit aufweist, um das Isoliermaterial 22 um den Lautsprecher 3 herum zu fixieren und um die spitzkegelförmige Lautsprechereinheit 2 in ihrer mittig angeordneten Lage zentral über dem Strahler 7 zu halten. Diese Zentrierung wird unterstützt durch die Kabelführung 4 , insbesondere wenn bevorzugt hierfür ein dünnes Rohr verwendet wird, bevorzugt aus hitzebeständigem Kunststoff.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.
Für die Wandung der Säule 5 wird bevorzugt ein Rohr aus Acrylglas verwendet, obgleich jedes andere lichtdurchlässige Material, wie z. B. sandgestrahltes Glas, gleichermaßen verwendet werden kann. Die Opazität und Farbe des Materials der hohlen Säule 5 kann nach Bedarf des Kunden variiert werden, wobei jedoch eine gewisse Lichtundurchlässigkeit zweckmäßig ist, um die Innenteile der Säule 5, nämlich insbesondere die Lautsprechereinheit 2 und die untere Beleuchtungseinheit 1 aus optischen Gründen abzudecken. Weitere optische Effekte sind mit Hohlglassäulen zu erzielen, welche teilweise grafische Elemente mit anderer Opazität als der restliche Teil aufweist.For the wall of the column 5, 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.
Bei Bedarf können zur Klangoptimierung noch zusätzliche Elemente, beispielsweise ein Hochtöner und/oder Reflektor 15 an der Oberseite der Lautsprechereinheit 2 angebracht werden, bevorzugt an dem Ring 18. Diese können, wie im vorliegenden Ausführungsbeispiel, unterseitig kegelförmig sein und so die Klangverteilung im Raum verbessern. Bevorzugt sind zur Steuerung der Lautsprechervorrichtung zwei Funkempfänger 9 und 16 im Sockel vorgesehen, mit denen sich die Funktionen sowohl der Beleuchtungseinheit 1 ferngesteuert bedienen lassen, insbesondere die Drehgeschwindigkeit der Filterscheibe 8 über eine Ansteuerung des Moters 10 und/oder die Lichtstärke des Strahlers 7 (Dimmerfunktion) .If required, additional elements, for example a tweeter and / or reflector 15, can be attached to the top of the loudspeaker unit 2, preferably on the ring 18, for sound optimization. These can, as in the present exemplary embodiment, be conical on the underside and thus improve the sound distribution in the room , Two radio receivers 9 and 16 are preferred for controlling the loudspeaker device 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).
Als Filterscheibe 8 wird eine Farbfilterscheibe mit mehreren Farben bevorzugt (vgl. unterschiedliche Schraffur der beispielsweise acht Sektoren in Fig. 2) , um an der Wandung der Säule 5 wechselnde Farben in schneller oder langsamer Folge und damit besondere optische Effekte zu erzeugen. Aufgrund der Wärme, welche beim Betrieb durch die Lichtquelle 7 entsteht, sind die Füße 6 an der Unterseite der Säule 5 vorteilhaft. Sie können aus unterschiedlichen Materialien (z. B. Holz, Metall, Kunststoff, Stein etc.) gefertigt sein und verschiedene Formen (zylinderförmig, kegelförmig, halbkugelig, pyramidal etc.) aufweisen. Es ist auch möglich, mehrere Lautsprecher 3 in die Säule 5 zu integrieren. Diese können sowohl im oberen Bereich als auch im Sockel angeordnet sein, z. B. ein zusätzlicher Baßlautsprecher im Fuß der Säule 5. 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. Because of the heat generated by the light source 7 during operation, 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.
