3 is a structural diagram of an electromagnetic brush provided by an embodiment of the present invention. As shown in FIG. 3, the electromagnetic brush includes a magnetic control circuit 301, a magnetic control selection switch 302, a pen holder 303, a metal fiber wire 304, and a flexible magnetic pole 305. The magnetic control circuit 301 and the magnetic control selection switch 302 are connected to the flexible magnetic pole 305 to form a magnetically controlled circuit (the power supply portion is included in the circuit, not separately listed). The pen holder 303 can be made of ordinary plastic or bamboo material, which is a bearing of the metal fiber wire 304 and the flexible magnetic pole 305, and needs to be fixed. The metal fiber wire 304 has a fine magnetic material, and the magnetic pole is attracted to the flexible magnetic pole 305, and the principle of magnetic pole anisotropy is used to ensure that the metal fiber wire 304 (equivalent to the pen) is easy to gather in the flexible process during the operation of the electromagnetic brush. Near the magnetic pole 305.

Among them, the magnetic control circuit 301 and the magnetic control selection switch 302 are not essential configurations of the present invention. When the magnetic control circuit 301 is not used, the metal fiber wire 304 and the flexible magnetic pole 305 are magnetically controlled. Directly for permanent magnetic metal materials (such as flexible magnetic pole 305 using a rubber-based, magnetic steel powder attached to the flexible magnetic pole of the rubber surface), then this design is not magnetic.

When the magnetic control circuit 301 is used and the magnetic control selection switch 302 is configured, the metal fiber wire 304 and the flexible magnetic pole 305 need to select a non-permanent metal material (for example, the flexible magnetic pole 305 uses a rubber-based flexible magnetic pole wrapped around the rubber surface). ). By selecting different pull codes or gear positions of the magnetic control selection switch 302, the circuit generates different magnitudes of current, thereby generating different intensity magnetic fields, affecting the dispersion effect of the flexible magnetic pole 305 and the metal fiber filament 304.

Example of use: According to the response characteristics of the capacitive screen and the corresponding software control on the device, when the electromagnetic brush runs on a device with a normal capacitive touch screen and an operating system, the 304 pen and 305 flexible magnetic poles (equivalent to the pen tip) together with the touch screen Contact, as the size of the contact surface of the pen tip and the capacitive screen changes, the operation of the pen tip from point to face is responded to on the multi-point capacitive sensing device, leaving a handwriting or trace (response area). After saving on the software, you can get the corresponding learning or creative effects. The size of the handwriting (response area) is related to the area responsiveness of the capacitive screen.

Since the display can be similar to the traditional writing brush similar to the writing experience. And the lack of ink to carry the difficulties, it is easy to make calligraphy and painting become a daily learning and creative behavior of more lovers.

Step S403: determining whether the obtained self-evaluation effect is acceptable;

Step S404: if the obtained self-evaluation effect is acceptable, perform calligraphy practice or creation, and save after completion;

Step S405: If the obtained self-evaluation effect is not accepted, the pen front magnetic field strength of the first electromagnetic brush is adjusted by changing the distance between the tip of the permanent magnetic metal material and the touch screen and the writing speed.
