Abstract
Embodiments of the present application relate to the technical field of terminals, and provide a key module and an electronic device. The key module is applied to an electronic device, and the electronic device comprises a middle frame. The key module comprises: a capacitive sensing structure, an elastic member, and pressure sensors. The capacitive sensing structure and the pressure sensors are separately connected to the elastic member, and the capacitive sensing structure is disposed on the side of the elastic member away from the middle frame. At least two pressure sensors are spaced apart from the capacitive sensing structure on the elastic member, and the at least two pressure sensors are distributed on two sides of the capacitive sensing structure. The capacitive sensing structure comprises a capacitive sensor module and a circuit board. The capacitive sensor module and the circuit board are stacked in a first direction, and the first direction is perpendicular to the side surface of the capacitive sensing structure away from the middle frame. In this way, the operation position and pressure magnitude of a user operation acting on a key can be detected, so that a corresponding function can be triggered on the basis of the operation position and the pressure magnitude, thereby improving the interaction efficiency of the key.
