  • Patent number: 11042231
    Abstract: A stylus structure includes a main body module, a control module, a modulation module, and a cover module. The main body module includes a stylus case unit and a movable unit. The control module includes a process unit and a transmission unit. The modulation module includes multiple sensing units. The cover module includes a stylus cover unit and multiple button units. When an outer opening of the movable unit corresponds to an inner opening of the stylus case unit and the transmission unit electrically connects an external power supply terminal, the transmission unit transmits power from the external power supply terminal to the process unit. When the sensing unit is pressed against a corresponding button unit, a sensing signal is generated by the sensing unit and transmitted to the process unit. The process unit according to the sensing signal sends a color signal to an external electronic device.
