Technical Field
[0001] The present application relates to the field of material processing technology, and in particular, to a diaphragm, a housing and an electronic device. Background Art
[0002] In the early days, the lighting effects on mobile phones were mainly in the form of LED breathing lights. For example, the "bubble" on the A side of the bubble phone has a breathing light hidden under it. When the user plays music, receives text messages or calls, the corresponding "bubble" will have a breathing effect. With the development of smart phones, mobile phone lighting effects have entered a new development, such as mini LED back covers. However, these technologies mainly use LED or mini LED side or bottom light emission, and then use light guide plates, light-distributing films, etc. to distribute light. The stacking thickness is thick and the power consumption is high. The effects are mainly presented in the form of marquees and breathing lights, which are relatively simple. Utility Model Content
