Abstract

The invention relates to an electronic pen used for an interactive electronic whiteboard, which comprises an electromagnetic wave generation device including electromagnetic oscillation circuits. The electromagnetic oscillation circuits include more than two electromagnetic oscillation member combinations and electromagnetic wave switches electrically connected to the combinations. Through the on-off states of the electromagnetic wave switches the electromagnetic oscillation circuits respectively obtain respective electromagnetic oscillation member combination for work and send the electromagnetic wave with individual frequency. The use of the electronic pen for the interactive electronic whiteboard enables the switching operation of common functions of an interactive demo system simple, enables the usage convenient and can realize the remote operation.

Description

[0001] This application relates to an electronic pen for an interactive electronic whiteboard, which is a divisional application with the application number "200610035492.3" and the title of the invention "An electronic pen for an interactive electronic whiteboard". technical field [0002] The present invention relates to an electronic pen, more specifically, to an electronic pen used for an interactive electronic whiteboard. Background technique [0003] In recent years, interactive electronic whiteboards using electromagnetic induction technology have appeared. This type of electromagnetic induction interactive electronic whiteboard can detect the position information written by the electronic pen, and can transmit the information to the connected computer. The position information and The computer screen images are integrated and projected onto the interactive electronic whiteboard through the projector, thus forming a complete interactive presentation system. Users can ...
