Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of key manufacturing, in particular to an inductive key structure applied to a mobile phone shell. Background Art
[0002] Currently, with the continuous development of technology, most of the buttons on mobile phones have been replaced by smart touch screens, leaving only a set of volume up and down buttons on the side of the phone case and the HOME button for turning the phone on and off. The remaining buttons are still mechanical buttons, so there is still a gap between the buttons and the case that allows the buttons to move. Dust always enters the gap and needs to be cleaned frequently, otherwise the dust accumulation in the gap will gradually affect the normal use of the phone. Therefore, a closed button structure for the phone is now designed, eliminating the traditional mechanical buttons and adopting a fully enclosed pressure touch module design. This achieves a physical button-free and button-free gap to prevent dust from entering the gap. A silk screen area is designed at the pressure button position to remind users of the pressure button. The pressure touch module detects its slight deformation to realize the power on and volume button functions. Utility Model Content
