A new detection method for mobile phone leather case

Abstract

The invention discloses a new type of detection method for a mobile phone leather case. Through certain software settings, the infrared detection device of the distance sensor included in the mobile phone is used to intelligently judge the opening and closing of the mobile phone case to realize the automatic detection of the mobile phone case. The detection does not need to add other devices for identification to the mobile phone or the leather case, which is convenient and easy, and does not require additional cost investment. In addition, by connecting the infrared detection device of the mobile phone with the communication module of the CPU processor of the mobile phone, it is possible to judge the situation of the face approaching the screen of the mobile phone during a call, and distinguish it from the closed state of the leather case; The device sets a certain time threshold, which can judge the situation when the palm or other objects are close to the screen during the use of the mobile phone, and also distinguish it from the closed state of the leather case, so that the opening and closing of the leather case can be controlled by the mobile phone's own device. Perform smart detection.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a novel detection method for a mobile phone leather case. Background technique [0002] At present, the screen of the mobile phone is getting bigger and bigger. In order to prevent the screen of the mobile phone from being scratched, the user will choose some leather cases to protect the screen, and the mobile phone needs to intelligently recognize the opening and closing of the leather case. In the prior art, magnets are added to the leather case of the mobile phone, and Hall switches are added to the main board of the mobile phone to detect the opening and closing of the leather case of the mobile phone. When the holster is opened, the Hall switch cannot detect the existence of the magnet, and informs the CPU that the holster has been opened; otherwise, the Hall switch detects the existence of the magnet, and notifies the CPU that the holster has been closed.

AI Technical Summary

Problems solved by technology

[0003] There are a series of disadvantages in the existing technology, such as adding a magnet to the leather case, and adding a Hall switch on the main board of the mobile phone, resulting in an increase in the cost of the whole machine; The space of the motherboard is limited, and magnetic components such as handsets and speakers of mobile phones need to be kept away, which is inconvenient for the layout of the motherboard. At the same time, adding magnets to the leather case is not convenient for production on the one hand, and on the other hand, the leather case is easy to be glued and damaged
