Multi-power supply rotary projection music box

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.

Description

technical field [0001] The present invention relates to a kind of daily necessities, more specifically, relates to a multi-power supply rotary projection music box. Background technique [0002] The traditional music box either uses springs as power or dry batteries as power, but the former must wind up the music box before each use, and the above process must be repeated after the energy stored in the springs is released. It is very inconvenient to use; although the latter can make the music box work for a relatively long time, but because the music box is not used every day, if the interval between two uses is too long, the dry battery will expire, and the electrolysis of its leakage The liquid will not only pollute the music box, but also cause certain environmental pollution; and in occasions where the music box needs to work for a longer time, such as image display in shopping malls or exhibitions, the above two methods cannot meet the needs of the site, so now The inh...

[0002] The traditional music box either uses springs as power or dry batteries as power, but the former must wind up the music box before each use, and the above process must be repeated after the energy stored in the springs is released. It is very inconvenient to use; although the latter can make the music box work for a relatively long time, but because the music box is not used every day, if the interval between two uses is too long, the dry battery will expire, and the electrolysis of its leakage The liquid will not only pollute the music box, but also cause certain environmental pollution; and in occasions where the music box needs to work for a longer time, such as image display in shopping malls or exhibitions, the above two methods cannot meet the needs of the site, so now The inherent defect of a single power supply method for music boxes is difficult to meet the diverse needs of different users and occasions

[0003] In addition, in the rotating music boxes with integrated light effects currently on the market, the projected light usually has only one pattern, which is set by the manufacturer, and the music box cannot be replaced after leaving the factory, which makes the overall feeling of the music box Relatively simple, it will lose freshness after a long time and affect the user experience
