摘要： A pressure detection module and an electronic device are provided. The pressure detection module includes: a first electrode, a second electrode, a first circuit board, a second circuit board, and at least two solder fixing parts. A first surface of the first circuit board is fixed to an inner surface of a force input area of the housing. A second surface of the first circuit board is fixed to a first surface of the first electrode. A first surface of the second circuit board is fixed to a second surface of the second electrode. Two end sides of the second surface of the first circuit board and two end sides of the first surface of the second circuit board are disposed opposed to each other through the at least two solder fixing parts. Thereby, the pressure detection module does not require a bracket and has a small thickness.

摘要： A pressure detection module and an electronic device are provided. The pressure detection module is disposed between a support and an inner surface of a housing of the electronic device. The pressure detection module includes a first electrode, a second electrode, and a controller. The first electrode is fixed to an inner surface of a force input region of the housing, the second electrode is fixed to the support, and the second electrode is disposed opposite to the first electrode. The force input region of the housing is configured to drive the first electrode to move towards the second electrode based on a received external pressure. The controller is configured to determine a pressure detection result of the external pressure based on a capacitance change between the first electrode and the second electrode. The pressure detection module occupies small space in the electronic device, and is easy to mount.
