Embodiment Construction
[0019] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, in the description of the present invention, when the electromagnetic pen is in use by the user, the relative One end of the writing surface is defined as the bottom, and then extends the concepts of bottom and bottom. The end of the electromagnetic pen away from the writing surface is defined as the top, and then extends the concepts of top and top. The following describes the present invention in conjunction with the accompanying drawings and specific embodiments. For further details.
[0020] Please refer to Figure 1~Figure 2 , The electromagnetic pen of the embodiment of the present invention includes a pen case 10, a first magnetic ring 20, a second magnetic ring 30, a pen core 40, an elastic component 50 and a resonant circuit (not shown in the figure).

The embodiment of the invention discloses an electromagnetic writing device and an electromagnetic pen. The electromagnetic pen comprises a hollow pen shell and a cartridge which is arranged in the pen shell; the electromagnetic pen further comprises a first magnetic ring, a second magnetic ring and a resonance circuit, wherein the first magnetic ring is movably contained in the pen shell; the second magnetic ring is fixed in the pen shell opposite to the first magnetic ring, and the opposite surfaces of the first magnetic ring and the second magnetic ring are curved surfaces which are fit with each other; and the resonance circuit generates electromagnetic signals according to the position variation of the first magnetic ring to the second magnetic ring, and comprises an inductance which is wound on the pen shell, corresponds to a first magnetic ring position and consists of a coil. The embodiment of the invention adopts a technical method that a fixed magnetic ring and a movable magnetic ring are oppositely arranged in the pen shell and the opposite surfaces of the two magnetic rings are the curved surfaces which are fit with each other, accordingly, the relative magnetic conduction area is increased, the magnetic permeability and inductance variation flexibility are high, and the electromagnetic pen has a technical effect in quickly capturing the information of pressure, track and the like at any time when being used by a user.
Description
technical field [0001] The invention relates to computer input equipment, in particular to an electromagnetic pen and an electromagnetic handwriting device. Background technique [0002] The electromagnetic pen is a commonly used computer peripheral product, and the equipment used with it is the electromagnetic board. The data such as the track coordinates and pressure of the electromagnetic pen moving on the electromagnetic board can be transmitted to the computer through the electromagnetic board, and then the purpose of writing and drawing can be realized. [0003] The measurement of the traditional electromagnetic board pressure sensitivity is mainly based on the phase change of the received signal waveform caused by the change of the inductance value in the electromagnetic pen. Quickly capture the user's pressure, trajectory and other information during use. Contents of the invention [0004] A technical problem to be solved by the embodiments of the present inventi...
