STYLUS PEN AND ELECTRONIC DEVICE ASSEMBLY COMPRISING THE STYLUS PEN

This application provides a stylus and an electronic device assembly. With a mainshaft and a pressure sensor assembly disposed in the stylus, one end of the mainshaft connected to a tip assembly, and the pressure sensor assembly fixed in a barrel assembly and touching the other end of the mainshaft, the tip assembly moves under a pressure and drives the mainshaft to move, the mainshaft transfers the pressure on the tip assembly to the pressure sensor assembly, and the pressure sensor assembly detects the pressure on the tip assembly. In this way, a transfer manner of the pressure on the tip assembly is simplified so that fewer components are disposed in the stylus, simplifying manufacturing and assembling processes of the stylus and resulting in low costs of the stylus. In addition, this can improve the accuracy of detection of the pressure on the tip assembly, thereby improving writing resolution of the tip assembly. With a second electrode fitting around a signal board, the moving of the tip assembly can drive the first electrode and the second electrode to move synchronously so that relative positions of the second electrode and the first electrode remain unchanged, improving measurement accuracy of a tilt angle of the stylus relative to a touchscreen by the electronic device.
