Abstract
The present invention relates to the field of pressure sensor technologies, and discloses a discrete pressure sensor and an electronic device. The pressure sensor includes a pressure sensing chip and a force centralization sensing board component that is bonded onto the pressure sensing chip. The force centralization sensing board component has a hollowed area, the hollowed area has a force centralization position for centralizing force applied on the force centralization sensing board component, and the force centralization position is disposed against the pressure sensing chip. After pressure is applied in the hollowed area of the force centralization sensing board component, force is centralized to the force centralization position, conveyed to the pressure sensing chip in a centralized manner, and converted into control information to control an external electronic device through a circuit or the like of the electronic device. The discrete pressure sensor has a simple structure, and does not have a high requirement on assembly precision. In an actual application, the discrete pressure sensor is directly bonded onto an inner side of a front panel of the electronic device, and a …
