Electronic teaching stick

Abstract

The invention relates to an electronic teaching stick which comprises a handle, a transmitting and receiving circuit, a switching push button, a play button, a connecting rod and a transmitting terminal, wherein both ends of the connecting rod are respectively connected with the transimitting terminal and the handle; the transmitting and receiving circuit is arranged in the handle and is electrically connected with the transmitting terminal by the connecting rod; the switching push button and the play button are respectively connected with the transmitting and receiving circuit and pass through the handle; the transmitting and receiving circuit is a carrier generator; the transmitting terminal is rotatably connected with the connecting rod; the connecting rod is connected with one end of the handle; the handle is stream line form, the connecting rod is an expansion link or a fixed link; the electronic teaching stick is used by being matched with the electronic whiteboard; and the transmitting and receiving circuit is a transmitting and receiving circuit of microwave electronic signals. The electronic teaching stick of the invention has ingenious design, low cost, is convinient to use, and greatly improves the working efficiency, has the electronic teaching stick function and the writing function, can not scratch the electronic whiteboard when writing, and lays a solid foundation for further development of modern education mode and teaching method.

Description

technical field [0001] The invention relates to the technical field of electronic education and long-distance conference systems, in particular to the technical field of electronic whiteboard matching devices, and specifically refers to an electronic teaching stick matched with the electronic whiteboard. Background technique [0002] In modern society, people pay more and more attention to education, and at the same time, more and more facilities and funds are invested in education. However, in the traditional teaching listening mode, there is often one blackboard in one classroom, and the students sitting behind cannot clearly see the words on the blackboard, causing eye fatigue, easy to form myopia, and at the same time unable to take notes completely, so It will greatly affect the efficiency and quality of the lectures. [0003] With the development of electronic technology, electronic whiteboards have appeared in recent years. After years of continuous development, ele...

AI Technical Summary

Problems solved by technology

Among them, the electromagnetic induction electronic whiteboard is easy to be scratched. Once a scratch occurs in the middle, the whole board may be scrapped, and because of the high cost of the receiving coil film, it is not realistic to make a large-area display panel, which brings inconvenience to use.

Infrared electronic whiteboards are easily affected by strong infrared light, and the positioning accuracy is not high

Ultrasonic electronic whiteboards are greatly affected by temperature, and the positioning accuracy is uneven

Resistive film electronic whiteboards are difficult to write. When the strength is not enough, the handwriting will not be displayed. Therefore, it is necessary to write hard, resulting in slower writing speed. In addition, it is easy to scratch, and once scratched, it cannot be used. In addition, due to The production cost is high, and it is not realistic to produce a large-area electronic whiteboard

[0004] Due to the existence of the above problems, and the electronic pen is too short, it does not have the function of the electronic teaching stick, therefore, it is necessary to provide a new electronic whiteboard and a supporting electronic teaching stick, so that the electronic teaching stick has the function of the electronic teaching stick and also has the function of writing Function, and writing will not scratch the electronic whiteboard, easy to use, low cost
