The portable multimedia device - the party-player - is an entertainment electronic device allowing downloading, recording, storage, uploading and playback of various audio-video content, karaoke and interconnecting of the remote users through internet in home or portable use mode. Besides that, it is possible to accompany the playback with simultaneous display of various programmable light effects normally used by professionals, in disco clubs and night clubs, at concerts, events, parties etc. Using the standard DMX protocol, it is possible to expand the device and control the additional light effect devices, thereby achieving appealing visualizations found in disco clubs, concerts etc. at home. The rotating disco-ball (22), an integral part of the multimedia device (10), consists of the base segment (70) powered by the electric motor (86) and the multiple secondary segments revolving around the concentrically arranged axes, and powered by the centrally located electric motor (40) through the wheel (72) and the axle (74). Power supply to the LE diodes, arranged uniformly across the segment surfaces, is performed through the brushes and the slip rings. |
