Home key and electronic equipment

Abstract

The invention relates to the technical field of electronic equipment, and discloses a Home key and electronic equipment. The Home key comprises a PCBA (Printed Circuit Board Assembly) board, a face shell with an isolation structure and at least two dome sheets; the at least two dome sheets are arranged on the PCBA board; the face shell is located above the PCBA board; a through hole is formed at a position corresponding to the PCBA board on the face shell; the isolation structure is located in the through hole and used for isolating the space above each dome sheet in the through hole; and the space above each dome sheet is isolated. Compared with the prior art, the Home key has the advantages that at least two dome sheets are arranged on the PCBA board of the Home key, each dome sheet can trigger a one-way electrical signal when being pressed down, and the different dome sheets can be pressed in various combination forms to generate various combined electrical signals, so that the Home key can realize multiple functions, the utilization rate of the Home key is improved and the cost of the electronic equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a Home key and electronic equipment. Background technique [0002] In current electronic devices (such as mobile phones), a Home button is generally set to realize the functions of returning to the main screen and fingerprint identification. [0003] However, in the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: at present, the Home button on the electronic device is generally only used to wake up the screen, trigger the function of returning to the main screen, and fingerprint recognition, and the function is too large. single. Moreover, the area occupied by the Home button is not small. If only the above functions are realized, the utilization rate is relatively low, which increases the cost of the electronic device. Contents of the invention [0004] The purpose of the e...
