Problems solved by technology

In the prior art, due to the lack of structural protection of the fingerprint identification module in electronic equipment, it is easy to be biased to a certain local area (such as left, right, etc.) ) makes the local stress too concentrated, which leads to the change of the fixed relationship between the components in the fingerprint recognition module, resulting in the failure of the fingerprint recognition function

Description

technical field [0001] The invention relates to terminal equipment, in particular to a key device and electronic equipment. Background technique [0002] With the popularization of fingerprint identification technology, more and more electronic devices (such as mobile phones, tablet computers, notebook computers, etc.) are equipped with fingerprint identification functions for security authentication. In the prior art, due to the lack of structural protection of the fingerprint recognition module in electronic equipment, it is easy to be biased to a certain local area (such as left, right, etc.) ) makes the local stress too concentrated, which leads to the change of the fixed relationship between the components in the fingerprint recognition module, resulting in the failure of the fingerprint recognition function. Contents of the invention [0003] In order to solve the existing technical problems, the embodiment of the present invention provides a button device and elect...
