Claim Text:
1. A projective capacitive stylus, comprising: a magnet having a first terminal and a second terminal; a winding allowing an entrance and an exit of the first terminal of the magnet, wherein when an external force causes the magnet and the winding to generate a first relative motion, a first current is generated on the winding; a spring connected to the second terminal of the magnet, wherein when the external force is removed, the spring causes the magnet and the winding to generate a second relative motion and causes a second current to be generated on the winding; and one of a conductor and an electric plate, configured on a tip of the stylus and electrically connected to the winding, wherein when the first current and the second current are respectively generated, a first signal and a second signal are correspondingly generated on an external touch panel via the one of the conductor and the electric plate; a button; and a connecting rod connected to the button and the magnet, wherein when the button is pressed, the external force generated thereby causes the connecting rod to move inward to drive the first terminal of the magnet to depart from the winding so as to generate a first induced reversal potential, which causes the second current to be generated on the winding; and when the button is released from being pushed down, the external force is removed, causing the spring to push the magnet back to a first original position to generate a first induced potential at this moment, which in turn causes the first current to be generated on the winding.
