[0042] The working principle of this embodiment is as follows:

[0043] A multifunctional starry sky projection lamp proposed by the present utility model can play music while the starry sky projection rotates synchronously with the music. The specific principle is as follows:

[0044] The power device 52 drives the transmission device 51 to start running. The power device 52 is a spring drive, a winding drive, a hand crank drive, or a battery drive. For example, the power device 52 drives the transmission device 51 to work by winding the spring.

[0045] When the transmission device 51 starts to operate, the driving gear 511 provided on the top of the sound cylinder 31 will rotate synchronously with the sound cylinder 31. The driven gear 512 meshing with the driving gear 511 will be driven by the driving gear 511 to rotate synchronously. At the same time, the projection lens 422 fixed on the driven gear 512 will also be driven by the driven gear 512 to rotate synchronously. Therefore, the starry sky projection projected by the projection light source 41 through the projection lens 422 will rotate with the rotation of the projection lens, and then the starry sky projection will rotate synchronously with the music playback while the playback component 30 plays music;

[0046] When the power device 52 no longer drives the transmission device 51 to operate, the driving gear 511 will stop with the stop of the rotation of the sound cylinder. At the same time, the driven gear 512 and the projection lens 422 fixed on the driven gear 512 will also stop rotating. Therefore, the starry sky projection will no longer rotate and project, and can only project statically.

[0047] Those of ordinary skill in the art should understand that: as described above is an implementation manner provided in combination with specific content, and it is not considered that the specific implementation of the present invention is only limited to these descriptions. At the same time, due to different industry names, it is not limited to the above names, nor limited to English names.
