Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically a speaker projection lamp. Background Technology

[0002] A speaker projection lamp is a type of light fixture capable of playing music, containing a lampshade for projecting images. The lampshade is typically secured to a turntable using clips or threads. The turntable, via a gear ring, meshes with the drive gear of a motor. When the motor operates, it drives the gear ring to rotate, thus rotating the lampshade. When powered on, the light from the LEDs shines onto the lampshade, projecting the image onto the wall.

[0003] However, the fastening method of clips or threaded connections is more troublesome to disassemble, and as the plastic parts age, disassembly can easily lead to wear or breakage of the connectors, resulting in a shorter service life.

[0004] In addition, to enhance aesthetics, some products add decorative elements to the top or sides, such as cartoon dolls or animal ears, to cater to children's tastes. These decorative elements are also mostly fixed using snap-fit ​​or interference fit, which makes them inconvenient to replace, easy to lose, or easily damaged. Utility Model Content
