Also, adjusting the rotation of the segment (70, 48, 58, 60) using the built-in controller, the music being played through random signal selection, which is a pre-programmed sequence or a user-programmed sequence change. It can also be achieved in response to.

  Apart from the lighting effects caused by the device itself, connect external devices, such as steerable directional multi-color floodlights, steerable multi-color laser beams, additional disco balls, smoke machines, foamers, etc. It is also possible. Control of such additional external devices may be performed using the standard DMX-512 protocol and accompanying standard cables, thereby connecting, programming and controlling devices compatible with existing DMX technology. As a result, practicality and universal use of the present invention can be promoted. Using appropriate software, the user himself or herself can program the ball motion sequence in sync with music or independently, brightness of light emitting diode and floodlight, flash device, invisible light, laser beam, rotating light , And other lighting effects, then, for example, link programmed sequences with karaoke lyrics to music or video content, upload them to the Internet, and other users download them , May be used. If supported by the manufacturer and the appropriate number of interested users, such an approach will compete to some extent between individuals and non-profit users in terms of making the recorded visual sequence as complex, rich and attractive as possible. As a result, other users may be encouraged to purchase new options that are compatible with existing equipment using DMX technology. Such optional devices can also be later technically developed and introduced to the market to maintain and expand user interest in party players.

  The relatively small rotating disco ball of this type of embodiment is instantly mechanically responsive and moves to a state where the ball segment is quickly and accurately controlled so that the interested user can Support can be used to create specific “dance” choreography for various movements of the rotating disco ball and other lighting effects, but the originality of the choreography will be limited only by the user's imagination.

A remote control (18) may be used to facilitate control of various functions of the device from a greater distance.

  FIG. 2 shows a partial cross-sectional view and shows the inside of an embodiment of a rotating disco ball. A rotating disco ball (22) is placed on the top surface of the device (10). The ball (22) has a light source (64) disposed on the surface of the base segment (70) of the ball (22) and on the surface of at least three secondary segments (48, 58, 60) of the ball (22). ) To distribute the movable beam. The segments (70, 48, 58, 60) are rotated by being driven by two electric motors (40, 86) that are individually operated, and the electric motor (86) and the drive wheels (84) are friction surfaces (82). , Thereby causing the base segment (70) to rotate within the ball's base bay (42) about the AA 'axis running through the second electric motor (40) axis, resulting in the axle ( 74) is rotated around the BB ′ axis that forms an oblique angle with the AA ′ axis passing through the large wheel (72) and the small wheel (46) located in the base segment (70). At the center of the ball, the spoke receiver (54) is fixed to the axle (74), and the secondary axle around which the secondary segment (48, 58, 60) rotates exits the differential; On the other hand, the light source (64) is disposed on the outer surface of all the segments (48, 58, 60, 70). In this embodiment, a suitable spring (62) is used to pressurize the friction surface. The secondary segments (48, 58, 60, 66) in contact with each other roll along the friction surface (68), while there are specific gaps (56) between these segments that turn in the same direction. To do. The segment size is variable, and the rotation speed of each segment is inversely proportional to its diameter. In this embodiment, a multi-color light emitting diode (64) is disposed on the outer surface of the segment, and the segment is driven through four independent channels in this example. Four independent channels are functioned using a suitable controller (FIG. 3), three primary brushes (44) and three metal slip rings (80) so that the base segment (70) and the segments Power is supplied to the installed light emitting diode. Furthermore, power is supplied through three secondary brushes (78) and a slip ring (76) arranged through an axle (74) that reaches the spoke receiver (54) and a conductor, Branching into secondary segments (48, 58, 60, 66), the light emitting diodes of each segment are driven through slip rings (52) and tertiary brushes (50). The conductor used for the power source of the light-emitting diode is not shown in FIG. 2 for simplicity and prevention of confusion, but FIG. 3 includes a wiring schematic diagram relating to the connection.

  The portable multimedia device (10) also includes means for raising and lowering the ball (22). The ball (22) is housed in the case of the device (10) and an appropriate cover is used when not operating. On the other hand, during operation, the base of the rotating disco ball (22) is flush with the upper surface of the device (10) from the inside of the device (10) using the lifting mechanism. Raise until fixed.

  To ensure that the ball motion reacts instantaneously and mechanically to the electrical signal sent to the electric drive motor, thereby ensuring that it moves quickly and changes its speed and direction quickly, the ball has a low mass. Considering its relatively small and simple structure, it is easy to achieve. For the same reason, the friction generated by the bearing around which the segment pivots is kept low. By applying pressure with the spring (62) compressed so that the segments are separated from each other, the friction is surely increased, thereby reducing the slip of the friction surface (68). It can also be a certain safety mechanism against entering between segments. Apart from that, safety can also be ensured by easily sliding the drive wheels (46 and 84) on the friction surfaces (72 and 82) and relatively reducing the power of the electric motors (40 and 86). it can. An automatic system designed to cut the drive mechanism when the ball becomes mechanically defective is also provided as appropriate.

  FIG. 3 shows a layout of conductors in the rotating disco ball. In this embodiment, four independent channels are provided to the controller, which converts the signal to an AC signal and provides it to the brush (44) and slip ring (80), and then further brushes (78). And to the slip ring (76) and to the associated secondary segments and their light emitting diodes through conductors, slip ring (52) and brush (50) disposed through the axle (74). All light emitting diodes in parallel with the same orientation as LED 11 are switched on with a positive voltage of L1 with respect to L0. All light emitting diodes in parallel with the same orientation as the LED 13 are switched on with the negative voltage of L1 with respect to L0. With the alternating voltage of L1 with respect to L0, the LEDs 11 and 13 are switched on simultaneously. Similarly, all light emitting diodes in parallel with the same orientation as LED 14 are switched on with a positive voltage of L2 with respect to L0. All light emitting diodes in parallel with the same orientation as LED 12 are switched on with a negative voltage of L2 with respect to L0. With the alternating voltage of L2 with respect to L0, the switch of LED12 and LED14 switches on simultaneously.

  The rotating disco ball may be created as a stand-alone element that resides on its own base, as depicted in FIG. In this type of embodiment, any number of devices can be connected independently to an existing party player using DMX technology or, for example, a PC, a portable computer, or another source of audio signals, or as a stand-alone device. Can be connected completely independently. Not only the size of the ball but also the number and size of the segments may be variable, and a ball including a display instead of a light emitting diode can be produced on the surface of the segment.

  For use in a disco club, a large-sized rotating disco ball can be constructed that is attached to the ceiling of the room as shown in FIG. Instead of using a friction surface, a gear transmission between segments may be employed. The ball may be placed ahead of the extension pipe (90), and its rotation, and thus the rotation of the base segment, is facilitated by a single electric motor and a suitable reducer. Moreover, with the 2nd electric motor accompanying use of a reduction gear, the 2nd axle shaft (92) which passes along this pipe (90) is rotated, and a secondary segment is rotated. Power is supplied to a light source or display disposed over the surface of the segment through conductors disposed along the axle (90) and through appropriately disposed brushes and slip rings. Because the total mass of this embodiment is large, the rotational speed and direction of the base and secondary segments cannot be changed as quickly as in the small version, but the operational appeal of this type of embodiment of the rotating disco ball And the overall appearance is not impaired.
