Problems solved by technology

[0003] At present, some edge touch functions have been realized by borrowing the existing capacitive touch screen of the mobile phone, but the above-mentioned edge touch function in the prior art is detected by using the capacitive touch screen, and the capacitive touch screen mainly senses the touch directly above the mobile phone. The front projection area on the side wall of the mobile phone is small and the distance is long. Therefore, it is not sensitive to the edge detection of the mobile phone. If there is a metal frame, it will affect the effect of edge detection even more.

Abstract

The invention provides an electronic device. The electronic device comprises a metal casing and at least two induction electrodes, wherein a window corresponding to each induction electrode is arranged on the metal casing, and each induction electrode is inlaid in the corresponding window and is electrically insulated from the metal casing; the electronic device further comprises an insulating layer wrapping the metal casing; the induction electrodes are used for generating variable capacitance when a user holds the electric device; the electric device further comprises a drive circuit and a processor, and the drive circuit is used for detecting the variable capacitance generated by the induction electrodes and converting the variable capacitance into an electric signal which can be processed by the processor; the processor is used for judging the holding gesture of the electric device according to the received electric signal sent by the drive circuit. According to the technical scheme, at least two induction electrodes are arranged in the metal casing to detect the held position of the electric device, the detection accuracy is improved, and the detection effect is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an electronic device. Background technique [0002] The needs of different grip postures can optimize user operations. For example, different antennas can be used to identify the left and right hands to make a call, thereby improving the quality of the call; The interaction is smarter and more convenient (especially one-handed operation). There are many solutions for detecting the proximity of a human body, but the more mature solution applicable to market application scenarios is the capacitive detection solution. Based on the principle of capacitive detection, it can determine the relative position of fingers or palms to the mobile phone, and then realize the recognition of hand gestures. [0003] At present, some edge touch functions have been realized by borrowing the existing capacitive touch screen of the mobile phone, but the above-mentioned edge touch fu...
