  • Patent number: 6078000
    Abstract: An improved structure of a magnet coupled type white glass ball transmission, more particularly an improved music white glass ball structure, being a breakthrough in the prior art that can generate only a single transmission and has a turning axle going into the white glass ball, which may lead to water leakage and requires use of an anti-leakage ferrule. By utilizing magnet coupled type white glass ball transmission, a rotor inside the glass ball can cause a propeller to rotate without making a through hole, so that swirls can be generated in the glass ball to drive floating particles or tinsels therein, thus creating a very beautiful scene. The power generated by the magnetic field drives a speed reduction gear set which transmit it to a turning disk at a reduced speed so that an ornament on the turning disk can turn round and round. Hence, a double transmission structure without making a through hole in the glass ball can be achieved.
