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.

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.
