Touch electronic pen

Abstract

The invention discloses a touch electronic pen, belonging to the technical field of electrons and comprising a shell, a pen head, a piezoelectric ceramic group, a driving module and a circuit part for processing voltage signals generated by the piezoelectric ceramic group and outputting the processed voltage signals to the driving module, wherein the pen head can be telescopically and elastically connected with one end of the shell; the shell and the pen head are internally provided with clamping structures for clamping the piezoelectric ceramic group; the driving module is fixed in the pen head and comprises a discharging tip; one end of the pen head is provided with a through groove; and the discharging tip is positioned in the through groove. In the touch electronic pen provided by the embodiment of the invention, the imaging of an electronic blackboard or an electronic whiteboard can be directly controlled, so that the imaging response time is short; and the electronic blackboard or the electronic whiteboard which is matched with the touch electronic pen does not need to sense a positioning layer to acquire a writing track, the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a touch electronic pen. Background technique [0002] With the development of science and technology, the teaching aids in daily teaching show a trend of being electronic. The existing electronic teaching aids usually include electronic blackboards or electronic whiteboards, and their matching electronic pens. Existing electronic blackboards or electronic whiteboards usually include a sensing positioning layer, a display layer and a control circuit. When the electronic pen writes on the electronic black and white or electronic whiteboard, the electronic black and white or electronic whiteboard captures the trajectory of the electronic pen through the induction positioning layer, and then controls the display layer to display the content written by the electronic pen through the control circuit. magnetic induction layer. [0003] There is an electronic pen in the prior art, ...

AI Technical Summary

Problems solved by technology

[0005] When using the existing electronic pen to write on the electronic blackboard or electronic whiteboard, the electronic blackboard or electronic whiteboard must first obtain the writing track through the induction positioning layer, and then control the imaging of the display layer, and the imaging response speed is slow

Moreover, due to the need to set the induction positioning layer, the manufacturing cost of the electronic blackboard and electronic whiteboard increases
