The key area 11 and the non-key area 12 connected with the key area 11 are arranged on the bearing main body 10, the key area 11 and the non-key area 12 are easy to deform simultaneously under the action of external pressing, the bearing main body 10 is fixedly connected through at least one first pressure sensing device 21 and senses at least one first pressure value transmitted to the key area 11, the bearing main body 10 is fixedly connected through at least one second pressure sensing device 22 and senses at least one second pressure value transmitted to the non-key area 12, when the key area 11 is directly pressed, the non-key area 12 indirectly bears pressure, and the at least one first pressure value is obviously larger than the at least one second pressure value; when the non-key area 12 is directly pressed, the key area 11 indirectly bears pressure, and the at least one second pressure value is obviously greater than the at least one first pressure value, so that the controller 30 can determine whether the key area 11 is pressed according to the at least one first pressure value and the at least one second pressure value, and the electronic device 100 can accurately distinguish the pressing operation of the user in the key area 11 and the non-key area 12, thereby avoiding false triggering of virtual keys.

In this embodiment, the main body 10 is a main body of the electronic device 100. The main carrying body 10 can carry a plurality of functional devices of the electronic apparatus 100, and the plurality of functional devices may include a camera module, a circuit board, a battery, a speaker module, and the like. The key area 11 on the main carrier 10 forms a virtual key, which can provide a key function, for example, the virtual key can be used as a volume key, an on/off key, a game key, or an application shortcut key, so that the number of physical keys on the main carrier 10 can be reduced, which is beneficial to implementing a hole-free design of the electronic device 100 and has a simple appearance.

Referring to fig. 3, the supporting body 10 is substantially rectangular plate-shaped. Wherein the main surface 13 and the edge side 14 are both outer surfaces of the load bearing body 10. The main surface 13 is substantially a long rectangular surface, the short side of the main surface 13 is parallel to the X direction, the long side of the main surface 13 is parallel to the Y direction, and the main surface 13 constitutes the front surface or the back surface of the bearing main body 10. The edge side 14 is connected to the major surface 13 at a long side or a short side, and the edge side 14 is parallel to the X direction or the Y direction. The specific shape of the edge side 14 can be set according to the need, for example, the edge side 14 can be an arc side or a flat side, which is not limited herein. In the present embodiment, the edge side surface 14 is connected to a long side of the main surface 13, and the edge side surface 14 is parallel to the Y direction.

The key region 11 is disposed on the edge side 14, and the key region 11 on the side of the carrier body 10 can implement a side key function of the electronic device 100. The non-key region 12 is disposed at the main surface 13 adjacent to the edge side 14, the non-key region 12 is connected to the key region 11, the non-key region 12 and the key region 11 are easily deformed simultaneously by an external pressing action, the main surface 13 may be a display surface of the electronic device 100 and/or a rear cover surface of the electronic device 100, when a user uses the electronic device 100, a portion of the main surface 13 adjacent to the key region 11 (i.e., the non-key region 12) may be pressed, and in order to avoid false triggering of a virtual key due to simultaneous deformation of the key region 11 and the non-key region 12, a pressing operation between the key region 11 and the non-key region 12 needs to be distinguished. In other embodiments, the key region 11 and the non-key region 12 may be located on the same plane, for example, both the key region 11 and the non-key region 12 are located on the main surface 13 or the edge side 14.

The application provides at least one first pressure sensing device 21 of the key module 20 to sense the pressing force of the key area 11, and at least one second pressure sensing device 22 to sense the pressing force of the non-key area 12, the controller 30 compares the pressure value sensed by the at least one first pressure sensing device 21 with the pressure value sensed by the at least one second pressure sensing device 22, when the at least one first pressure value is greater than or equal to the at least one second pressure value, the controller 30 determines a key signal according to the at least one first pressure value, that is, determines that the key area 11 is pressed, and triggers the key signal, thereby realizing the volume adjustment or the on-off function; when the at least one first pressure value is smaller than the at least one second pressure value, the controller 30 determines that the non-key area 12 is pressed, and the pressing force of the key area 11 is caused by the deformation of the non-key area 12, so that a key signal does not need to be triggered, and the situation of mistakenly touching can be avoided.

Referring to fig. 4 and 5, the first pressure sensing device 21 may be a resistive pressure sensor. The first pressure sensing device 21 includes a substrate 23, a plurality of piezoresistors 24 disposed on the substrate 23, and a plurality of pads 25, wherein each pad 25 is electrically connected between two adjacent piezoresistors 24, so that the plurality of pads 25 and the plurality of piezoresistors 24 form a wheatstone bridge, and the plurality of pads 25 are all fixedly connected and abutted against the supporting body 10. The substrate 23 may be a silicon substrate 23, and the number of the piezoresistors 24 may be greater than or equal to four. When no external force acts on the key region 11 and the non-key region 12, the wheatstone bridge is in a balanced state, and the output voltage is zero. When the key region 11 is pressed externally, the key region 11 can deform and transmit to the first pressure sensing device 21, so that the piezoresistors 24 deform to change the resistance, and further the wheatstone bridge loses balance and generates an output voltage positively correlated to the detected pressure. When the non-key region 12 is pressed by the outside, the key region 11 is indirectly pressed and deformed, and the key region 11 may also be deformed and transmitted to the first pressure sensing device 21. In another embodiment, the first pressure sensing device 21 may be a capacitive pressure sensor, a resonant pressure sensor, or a pressure sensitive strain gauge.

When a user presses the key region 11, the X-direction deformation generated by the carrier body 10 in the key region 11 is relatively large, and the Z-direction deformation generated by the carrier body 10 in the non-key region 12 is relatively small, so that the at least one first pressure sensing device 21 can sense a relatively large X-direction pressing force, and the at least one second pressure sensing device 22 can sense a relatively small Z-direction pressing force; when a user presses the non-key area 12, the X-direction deformation generated by the carrier body 10 in the key area 11 is relatively small, and the Z-direction deformation generated by the carrier body 10 in the non-key area 12 is relatively large, so that the at least one first pressure sensing device 21 can sense a relatively small X-direction pressing force, and the at least one second pressure sensing device 22 can sense a relatively large Z-direction pressing force, so that the controller 30 can distinguish the pressing operations of the user in the key area 11 and the non-key area 12 by comparing the pressures sensed by the at least one first pressure sensing device 21 and the at least one second pressure sensing device 22, and can avoid the situation that the user presses the screen side or the back plate 34 to generate a wrong touch.
