Embodiment Construction

[0021] The present invention will be described in further detail below with regard to specific schemes in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, it is a three-dimensional structural schematic diagram of an embodiment of an electromagnetic induction electronic whiteboard with a board-card separation wire mesh winding according to the present invention. It not only solves the problem of the strength of the board itself, but also shields the electromagnetic signal from the outside, so as to have a better anti-interference effect, so that the board-card separation wire mesh of the present invention is wound into an electromagnetic induction type electronic whiteboard It can adapt to various working environments; on the bottom plate 1 is the wire mesh 2, and by adopting the improved winding scheme, the number of wire numbers is reduced from about 200 to 42, which not only simplifies the winding, welding process and control circuit, reduces ...

Abstract

The invention relates to a board-card separation wire net wound electromagnetic induction type electronic white board. The board body of the board-card separation wire net wound electromagnetic induction type electronic white board is divided into three layers in structure, wherein the lowest layer is a bottom board; a wire net is formed above the bottom board; and the uppermost layer is an interaction interface. By adopting a new electromagnetic induction type electronic white board wire net winding scheme, board-card separation is realized; and a wiring board and related circuits are unnecessarily arranged around the board body, so that great convenience is brought to production and maintenance.

Description

technical field [0001] The patent of the present invention relates to a new electronic whiteboard, especially a board-card separation wire net winding electromagnetic induction type electronic whiteboard that can truly realize the separation of boards and cards and supports multi-stroke operations. Background technique [0002] Today's society has entered the information age, and as a derivative product of computers, electronic whiteboards have gradually entered people's work, study, and life. Due to its unique features, it is compatible with most computer software and is gradually replacing the use of blackboards and projection screens. At present, most of the electronic whiteboards on the market are made by using the principle of electromagnetic induction, which are called electromagnetic induction electronic whiteboards. This electromagnetic induction electronic whiteboard can detect the coordinate information written or operated by the electromagnetic pen on the board, ...
