The force used during writing is different for each stroke and thus the vibration generated by the pencil 200 is different. The detecting piece can detect the difference of the intensity of vibration and identify different vibration signals. Since the circuit board 120 can trigger the transmitting signal adapted to the different degrees of strength according to the vibration signal of different degrees of strength. Therefore, when writing, the writing board can obtain the force applied to the pen tip 220, and the thickness of the handwriting can be displayed according to the force applied to the pen tip 220. In this way, handwriting of different users can be distinguished, and when the pencil 200 of the intelligent accessory 100 of the present invention is used for operations such as drawing, the display device can distinguish different lines, which is convenient for other users to watch.
