Adjustable electronic blackboard

Abstract

The invention discloses an adjustable electronic blackboard, and the blackboard comprises rolling wheels, a pedestal, lower rods, fixing buttons, upper rods, cross bars, a frame, an installation plate, an electronic blackboard body, rotating shafts, a support, a microphone, a computer, a sound box, a heat dissipation hole, and a cooling fin. The lower end of the pedestal is provided with the rolling wheels, and two sides of the upper end of the pedestal are respectively provided with one lower rod, wherein the lower rods are respectively of a hollow structure. The upper rods are sleeved by the lower rods, and are fixed at positions where the upper rods are opposite to the lower rods. The upper ends of the upper rods are connected with the cross bars, and the two cross bars are respectively in rotating connection with the left and right sides of the frame. The upper and lower sides of the frame are respectively connected with the installation plate through the rotating shafts. The installation plate is provided with the electronic blackboard body, and the electronic blackboard body is connected with the computer through a wire. The computer is connected with the microphone and the sound box, and the microphone is installed on the support. The support, the sound box and the computer are all installed on the pedestal. Through the connection of the microphone and the sound box to the computer, the blackboard can facilitate the exchange between teachers and students.

Description

technical field [0001] The invention relates to an electronic blackboard, in particular to an adjustable electronic blackboard. Background technique [0002] The electronic blackboard adopts stable and reliable infrared sensor positioning technology, liquid crystal display technology and computer technology in one. The software makes the information processing more convenient, the demonstration more vivid, and does not require complicated installation and debugging, which reduces the system cost. [0003] The electronic blackboard has developed from the previous single-point touch to the current multi-point touch, which makes the teacher's teaching develop from the plane to the space, and gradually realizes the interactive use of computers and humans. The lens of previous science fiction movies is gradually being realized. People's life in the future will be accompanied by the application of electronic blackboards. [0004] Electronic blackboards are gradually being popula...

AI Technical Summary

Problems solved by technology

[0005] Existing electronic blackboards generally have an integrated structure. The electronic blackboard is fixedly installed on the wall, which makes it inconvenient to adjust the electronic blackboard. Moreover, the functions of the electronic blackboard are relatively single, and it is inconvenient to communicate between teachers and students during class. Therefore, it is necessary to An electronic blackboard to solve these defects and improve the teaching efficiency of teachers
