Abstract

A device to produce lighting effects partic. on walls of discotheques etc. has a flexible mirror attached to a piston which is activated by pressure waves from a loudspeaker in speaker box which travel along tube into resonating chamber. A light source surrounded partially by a focussing mirror directs light onto the flexible mirror which then reflects it onto a wall etc. producing light effects in time with the vibrations derived from the loudspeaker. The mirror is only supported on one side and in a preferred alternative system the piston-cylinder assembly can be replaced by an electro-mechanical device.

Description

VORRICHTUNG ZUR ERZEUGUNG VON LICHTEFFEKTEN Die Erfindung bezieht sich auf eine Vorrichtung, Lichtstrahlen einer oder mehrerer Lichtquellen (Glühbirnen) abzulenken durch die Einwirkung von niederfrequenten Schalldruckwellen einer Lautsprecherboxq Bekannt sind Geräte mit Thyristoren oder Transistorverstärker die in elektrischer Verbindung mit Tonfrequenzerzeugern zum Beispiel Tonbandgeräte oder Rundfunkgeräte, Glühbirnen im Rhythmus der Tonschwankungen hell - dunkel modulieren.DEVICE FOR GENERATING LIGHT EFFECTS The invention relates to focus on a device, rays of light from one or more light sources (lightbulbs) distracted by the action of low-frequency sound pressure waves from a loudspeaker box Devices with thyristors or transistor amplifiers are known in electrical Connection to audio frequency generators, for example tape recorders or radios, Modulate light bulbs light - dark in the rhythm of the tone fluctuations.

Ibr Erfindung liegt die Aufgabe zugrunde, auf einfache Art Lichteffekte zum Beispiel an Zimmerwänden oder auf Mattglasscheiben im Rhythmus von Tonschwankungen zu erzeugen.The invention is based on the object of creating light effects in a simple manner for example on room walls or on frosted glass panes in the rhythm of tone fluctuations to create.

Die Vorrichtung (Zeichnung Fig. 1) besteht aus einem flexiblen Spiegel (6) der mit einem Druckkolben (4) welcher sich in einem Zylinder (5) befindet mechanisch verbunden ist. Vor dem Spiegel (6) ist eine Lichtquelle angeordnet. (7) Der Zylinder (5) ist über ein Luftschlauch (3) oder Rohr mit dem Innenraum einer Lautsprecherbox verbunden. Durch die Bewegung der Lautsprechermembran (1) werden in der luftdicht abgeschlossenen Lautsprecherbox (2) Druckwellen erzeugt. Diese Luftdruckwellen drücken auf den Kolben (4) der die Bewegung auf den Spiegel (6) überträgt. Da der Spiegel (6) an den äußeren Seiten Seiten festgehalten wird, nimmt der Spiegel je nach Luftdruckart eine plane, konkav oder konvex Form an. Das von der Lichtquelle auf den Spiegel auftreffende Licht (9) wird je nach Spiegel form gebündelt oder im breitem Winkel reflektiert an die angenommene Zimmerwand projekXxziert. Ein Reflektor (8) ist so angeordnet, daß das Licht der Glühbirne direkt nur den Spiegel trifft.The device (drawing Fig. 1) consists of a flexible mirror (6) with a pressure piston (4) which is located in a cylinder (5) mechanically connected is. A light source is arranged in front of the mirror (6). (7) The cylinder (5) is connected to the interior of a loudspeaker box via an air hose (3) or pipe tied together. The movement of the speaker membrane (1) makes the airtight closed loudspeaker box (2) generates pressure waves. These air pressure waves push on the piston (4) which transfers the movement to the mirror (6). Because the mirror (6) is held on the outer sides sides, the mirror increases depending on the type of air pressure a flat, concave or convex shape. That from the light source to the mirror incident light (9) is bundled depending on the mirror shape or at a wide angle reflected projected onto the assumed room wall. A reflector (8) is like this arranged that the light from the light bulb hits the mirror directly.

Die Anordnung von mehreren farblich unterschiedlichen Lichtquellen vor dem Spiegel erhöhen die Wirksamkeit der auftretenden Lichteffekte.The arrangement of several different colored light sources in front of the mirror increase the effectiveness of the lighting effects that occur.

Wie in der Abbildung Fig. 3 dargestellt ist auch die Möglichkeit gegeben, den Spiegel (6) direkt in die Wand der Lautsprecherbox (2) einzubauen.As shown in Fig. 3, it is also possible to to build the mirror (6) directly into the wall of the loudspeaker box (2).

Die in der Lautsprecherbox (2) entstehenden Luftdruckschwankungen wirken dann direkt auf den Spiegel und verformen ihn.The fluctuations in air pressure occurring in the loudspeaker box (2) then act directly on the mirror and deform it.

Wird wie in Abbildung Fig. 2 ein Spiegel (11) verwendet, der nur an einer Seite (13) gelagert ist, so wird der Spiegel bei Luftdruckschwankungen in der Lautsprecherbox (2) nur in seiner Lage verändert. Ein Lichtstrahl der auf diesen Spiegel trifft wird abgelenkt. Beispielsweise könnte der Lichtstrahl der auf eine Mattglasscheibe trifft, durch den Grad der Ablenkung, in bezug auf die Lautstärke des Tones gebracht werden.If, as in Figure 2, a mirror (11) is used, which is only on is mounted on one side (13), the mirror is in the loudspeaker box (2) has only changed its position. A ray of light on these Mirror hits is distracted. For example, the light beam on a Matt glass pane hits, due to the degree of distraction, in terms of volume of the sound.

Die pneumatische Einrichtung bestehend aus Zylinder (5) und Kolben (4) kann auch durch ein elektromagnetisches System ersetzt werden.The pneumatic device consists of cylinder (5) and piston (4) can also be replaced by an electromagnetic system.

Dadurch, daß die Verbindung (3) zwischen Lautsprecher und Spiegel auch aus einem flexiblen Schlauch bestehen kann, ist es möglich, de Anordnung (5-12) auch in einem von der Lautsprecherbox getrennten Gehäuse unterzubringen.Because the connection (3) between loudspeaker and mirror can also consist of a flexible hose, it is possible to arrange the arrangement (5-12) can also be accommodated in a housing separate from the loudspeaker box.
