Description

Electromagnetic handwriting board with screen protection structure Technical Field The utility model belongs to the technical field of electromagnetic handwriting boards, and particularly relates to an electromagnetic handwriting board with a screen protection structure. Background Electromagnetic sensing technology has the characteristics of high resolution, difficult influence of the outside and the like, and is widely and widely applied at present. The wireless passive electromagnetic sensing technology in the electromagnetic sensing technology is the highest level of the current electromagnetic sensing technology because the electromagnetic pen does not need to receive excitation from the electromagnetic board through a wire and the electromagnetic pen is not provided with a battery, thus being easy to miniaturize, and the wireless passive electromagnetic sensing technology has been widely applied to various fields such as drawing boards, drawing screens, embedded products and the like. The working principle of the wireless passive electromagnetic sensing technology is that the electromagnetic plate emits electromagnetic waves with the same or similar resonant frequency as the resonant circuit built in the electromagnetic pen, when the electromagnetic pen receives the electromagnetic waves emitted by the electromagnetic plate, the resonant circuit generates resonance, so that electric energy is generated in the electromagnetic pen, and the electromagnetic pen emits electromagnetic waves with the same frequency as the resonant frequency of the electromagnetic pen to the electromagnetic plate.
