Description

A key structure and electronic device

technical field

The invention relates to a button structure, more specifically, the invention relates to a structure capable of simulating a traditional button; the invention also relates to an electronic device.

Background technique

With the development of science and technology, electronic devices such as mobile phones and computers have become indispensable tools in our lives. Modern smart phones have fewer and fewer buttons, and almost all of them are changed to touch screen forms. But there are still some buttons that have been continued, such as the power button on the side, the volume button on the side, etc.

However, the existence of these buttons seriously affects the appearance size of the mobile phone, which is not aesthetically pleasing and has relatively single functions. And after these control buttons are assembled with the housing of the mobile phone, there must be a gap for the button action between the control buttons and the mobile phone housing, especially the commonly used volume keys or the like. These gaps will inevitably affect the water resistance of the mobile phone.

In order to solve this problem, electronic manufacturers have introduced a key structure based on a pressure sensor, which can be integrated with the housing of the electronic device, thereby solving the problems of waterproofing and aesthetics. However, this button structure cancels the traditional button feel that users have been used to for many years, such as button sound or touch, making the user experience poor.
