Key detection device and electronic equipment

Abstract

The invention provides a key detection device and electronic equipment, the key detection device is applied to the electronic equipment, the electronic equipment comprises a shell, the shell comprisesa pressing surface, and the key detection device comprises a detection circuit, and a touch sensing layer and a capacitor assembly which are arranged away from the pressing surface; the touch sensinglayer is used for sensing whether touch operation exists on the pressing surface or not, and the capacitor assembly is used for sensing whether pressing operation exists on the pressing surface or not; the key detection device also comprises a detection circuit which is in signal connection with the touch sensing layer and the capacitor assembly; the detection circuit is used for generating a trigger signal when the touch sensing layer senses that touch operation exists on the pressing surface and the capacitor assembly senses that pressing operation exists on the pressing surface. The key detection device provided by the invention can effectively prevent the occurrence of a mistaken touch condition.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a key detection device and electronic equipment. Background technique [0002] With the continuous development of electronic equipment, the industry has higher requirements for the performance of electronic equipment in all aspects. Taking mobile phones as an example, mechanical buttons are usually set in the mobile phone to realize functions such as volume adjustment and taking pictures. For the operability of the mechanical buttons, there will be a certain gap between the mechanical buttons and the mobile phone casing, but this structure will easily allow impurities such as water and dust to enter the interior of the mobile phone through the gap, thereby affecting the normal use of the mobile phone. In order to avoid opening gaps and affecting the waterproof and dustproof performance of mobile phones, some manufacturers have begun to use pressure-sensiti...

Taking mobile phones as an example, mechanical buttons are usually set in the mobile phone to realize functions such as volume adjustment and taking pictures. The operability of the mechanical button, there will be a certain gap between the mechanical button and the mobile phone shell, but this structure is easy to allow impurities such as water and dust to enter the interior of the mobile phone through the gap, thus affecting the normal use of the mobile phone

In order to avoid opening gaps and affecting the waterproof and dustproof performance of mobile phones, some manufacturers have begun to use pressure-sensitive materials and piezoresistive sensors to replace traditional mechanical buttons. touch risk, therefore, will reduce the user experience
