- The stylus according to claim 15, wherein the first pressure sensor detects a pressure value in an axial direction of the pen core and transmits a first signal to the micro control unit, the second pressure sensor detects a pressure value in a radial direction of the pen core and transmits a second signal to the micro control unit, and the micro control unit receives the first signal and the second signal, calculates the first signal and the second signal, and controls the switching dc boost circuit to output a high voltage pulse signal corresponding to the pressure value in the axial direction and the pressure value in the radial direction.
- The stylus of claim 15, wherein the first pressure sensor and the second pressure sensor send respective pressure values to the micro-control unit in a time-division multiplexing manner, and the micro-control unit controls a transmission frequency and a transmission time of a high-voltage pulse signal output by the switch dc boost circuit.
- The stylus of claim 15, wherein the voltage of the high voltage pulse signal output by the switching dc boost circuit is 5-30V.
- The stylus of claim 15, wherein the switching dc boost circuit outputs a square wave signal having a voltage of 5-30V.
- A handwriting input apparatus comprising a handwriting pad, characterized in that said handwriting input apparatus further comprises a touch-control pen according to any one of claims 1-19, said handwriting pad is used for sensing pressure information of pressure values detected by a first pressure sensor and a second pressure sensor of said touch-control pen and transmitting said pressure information to an external device.
