Abstract
The invention relates to a multi-power supply rotary projection music box. The music box comprises a base, a control unit, a light source, a rotary mechanism and a sounding device, as well as a dry cell box, a solar photovoltaic cell and an external power plug, wherein the light source, the rotary mechanism and the sounding device are connected with the control unit, and the dry cell box, the solar photovoltaic cell and the external power plug are connected with the control unit. The rotary mechanism comprises a transparent cover rotating around a plumb line passing though the base under the driving of a micro motor, wherein the transparent cover is provided with a projection pattern, and the light source is arranged in the transparent cover. In the music box, the solar photovoltaic cell is arranged and used as a power supply, thereby achieving the effects of energy conservation and environment protection; meanwhile, the dry cell box and the external power plug are integrated, thereby diversifying the power supply modes of the music box; the projection pattern is arranged on the transparent cover so that projection images can be formed around the music box when the music box works, thereby enhancing the expression of the music box; moreover, since the pattern on the transparent cover can be replaced, a user can select different projection patterns according to actual conditions so that the music box can be closer to specific atmospheres.
