Definitions

• the invention relates to a device for generating light effects, with two coaxially arranged disks having t openings, one of which is driven to rotate and at least one of which is illuminated by a light source.
• Light source is arranged, wherein the disks are either transparent or provided with openings. With such a device, a flowing light effect can be generated.
• the invention has set itself the task of designing an initially described device for generating light effects in such a way that, on the one hand, the drive of the rotating disk is simplified, on the other hand, this device can be combined with a loudspeaker, without this being the case for the user Loudspeaker required space is significantly increased.
• the invention proposes that the rotating disk be arranged at the opening of the membrane of a loudspeaker, and that means for the relative movement of the two disks are actuated by the vibrations of the membrane.
• the invention takes advantage of the fact that, when the loudspeaker is in operation, the loudspeaker diaphragm carries out vibrations which can be used to drive the rotating disk, so that no electric motor or similar separate devices are required for this drive .
• the means preferably have at least one driver which is fastened to the rotating disk or to the membrane and with its free end rests frictionally on the membrane or on the rotating disk. It • has It has been shown that, with a suitable design of such drivers, the desired rotary movement of the rotating disk takes place by frictional entrainment, in particular in the frequency range of the loudspeaker between 60 and 120 Hz.
• the combination between the device for generating light effects and a loudspeaker has the advantage with the fact that it can be accommodated in a common housing, an enlargement of the housing accommodating the loudspeaker not being necessary.
• the device according to the invention can be used wherever loudspeaker transmissions take place and lighting effects are to be achieved, for example when singers or musicians appear, where a microphone transmission takes place, in discotheques or at similar events.
• the rotating disk covers the opening of the diaphragm of the loudspeaker, which results in the greatest possible effects.
• the driver can consist of a wire bent in the form of a screw line section.
• the free end of the wire lies tangentially against the surface of the rotating disk, so that the vibration movement of the loudspeaker diaphragm is converted into a rotary movement of the rotating disk is ensured.
• the rotating disk on the side facing the membrane expediently has a ring against which the driver bears. This ring reinforces the disk in the area where the driver acts on the disk so that deformations of the disk are avoided there, and ensures a completely flat contact surface for the driver, which is necessary for the device according to the invention to function properly is.
• the driver can be glued to the membrane, preferably by means of an epoxy adhesive.
• the free end of the driver which is in contact with the rotating disc is provided with a cap made of sound-absorbing material, e.g. made of rubber or rubber-like material. This avoids disturbing noises that may otherwise occur when the driver moves the rotating disc.
• fertilizer the driver can consist of a fiber bundle, preferably carbon fibers, which is arranged obliquely to the axis of the membrane.
• This fiber bundle is preferably fastened to the rotating disk and lies with its free end on an outer ring of the membrane.
• Such a fiber bundle reliably transmits the vibrations of the membrane to the rotating disk, without disturbing noises or mechanical stress on the membrane or disk.
• the light source can be arranged within the diaphragm of the loudspeaker, the diaphragm preferably being provided with a light-reflecting coating.
• Such an embodiment has the advantage that no additional space is required for accommodating the light source, since in the large loudspeakers used in practice there is sufficient space within the membrane for accommodating the light source.
• the membrane can also serve as a reflector.
• the light emitted by the light source emerges through the translucent openings in the disks, the desired light effects being brought about by the changing overlap of the two disks during the rotational movement of the rotating disk.
• the light source can also be arranged outside the membrane or the housing receiving the loudspeaker, so that the side of a pane facing the viewer is illuminated by a light source, for example a headlight.
• a light source for example a headlight.
• the other, rotating disk must be provided with a light-reflecting coating on its side facing the viewer.
• the rotary movement of the rotating disk causes a different reflection of the light, as a result of which the desired light effects occur. Additional effects can be brought about by the fact that the rotating disk has at its edge a bend provided with openings and / or cutouts, to which light from at least one light source is directed.
• Fig.l shows a section through a first embodiment of the device according to the invention along the line II in Fig.2.
• 2 shows a plan view of the device according to the invention, but the outer pane has been omitted and the inner pane has been partially broken away.
• Figure 3 shows a section along the line III-III in Figure 2.
• 4 shows a second embodiment of the device according to the invention in a section similar to FIG.
• the device according to FIGS. 1 to 3 has a loudspeaker 1 with a membrane 2.
• the edge 3 of the loudspeaker 1 and the outer ring 16 of the diaphragm 2 are fastened to a frame 4 which can form part of the housing 25 of the device.
• the membrane 2 is covered by a rotating disk 5 and by a fixed disk 6.
• Both panes 5, 6 are provided with openings 18 and 19, respectively, these disks are expediently designed as perforated disks or as a speaker grille.
• the fixed disc 6 is supported by a flange 7 on the frame 4 and has a bearing pin 8 on which a bearing 8 of the rotating disc 5 is mounted, which rotates about the axis 17 of the loudspeaker 1 or the device.
• Light sources 10 are arranged within the membrane 2. During the rotating movement of the rotating disk 5, the alternating overlapping of the openings 18, 19 in the two disks 5,6 results in light effects to the outside. The openings in these panes also serve to allow the sound to emerge from
• each driver 11 consists of a wire which is bent in the form of a helical line section and at 12 on one '. from the truncated cone-shaped part of the membrane 2 to the outside projecting ring part 13 is fixed by gluing, for example by means of an epoxy adhesive.
• the free end of each driver 11 has a cap 14 made of a sound-absorbing material, which abuts a ring 15 which is arranged on the rotating disk 5 and protrudes in the direction of the membrane 2.
• the Schwingun ⁇ occurring during operation of the speaker 1 of the membrane 2 gene occurs, in particular at frequencies between 60 and 120 Hz, a movement of the driver 11, which caps 14 by Rei ⁇ bung circuit to the ring 15 and thus to the disk 5 is transmitted such that a rotary movement of this disc 5 takes place about the axis 17 without an electric motor or a similar drive being required for this.
• drivers 21 also serve as rotary drives for the disk 5, but are formed by brush-like carbon fiber bundles. Each of these carbon fiber bundles is fastened to the disk 5 with a holder 22, the axis of the respective carbon fiber bundle being arranged obliquely to the axis 17.
• the free ends of the drivers 21 formed by the carbon fiber bundles rest on an outer ring 16 of the membrane 2.
• This outer ring 16 can be proportionate 1 be rigid, but transmits the vibrations of the diaphragm 2 to the drivers 21, of which three or four are expediently arranged at regular intervals around the circumference of the outer ring 16.
