Description

Technical Field

[0001] The utility model relates to the technical field of metal shrapnel production for mobile phone buttons, in particular to a mobile phone shrapnel structure. Background Art

[0002] As mobile phones become increasingly versatile and space is limited, the volume button may have to share space with other buttons or functions, which may lead to some compromises in button design. For example, the volume button shares a button with other functions such as the power button and shortcut keys. As a result, people have more demand for the use of the volume button. However, since the volume button is usually a physical button and the button is exposed to the outside for a long time, it is inevitable that it will be accidentally touched during use. After long-term and frequent pressing, the button spring structure may be damaged or worn, and the button may become loose or malfunction, thereby affecting its reliability and durability. Therefore, it is very easy to affect the use effect and the stability of its own use. Utility Model Content
