Electronic Blackboard for Multimedia Classroom

Abstract

The invention belongs to the technical field of teaching appliances, and particularly relates to an electric blackboard for a multi-media classroom. The electric blackboard comprises a rectangular blackboard body allowing for writing, a nanometer touch control display screen for displaying, an upper fixing plate, a lower fixing plate, an infrared position sensor, a walking unit and a controller, wherein the upper fixing plate is fixedly mounted on the blackboard body; the lower fixing plate is fixedly mounted below the blackboard body; and the upper fixing plate and the lower fixing plate areboth used for reinforcing the blackboard body. According to the electric blackboard disclosed by the invention, through the cooperation of the blackboard body, the nanometer touch control display screen, the infrared position sensor and the walking unit, the horizontal movement of the nanometer touch control screen can be realized, and the situation that a lecturer shelters the nanometer touch control display screen, so that seeing information of students on the nanometer touch control display screen is influenced is avoided.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to an electronic blackboard for a multimedia classroom. Background technique [0002] Because the traditional blackboard needs to use a pen to write pictures and texts on the blackboard for the convenience of teaching, however, a lot of teaching content is repeated. After the blackboard is wiped, it needs to be rewritten, which makes the teaching efficiency lower. Therefore, the electronic blackboard Emerged as the times require, the lecturer only needs to store the repeated content in the computer in advance, and then release it through the electronic blackboard, which improves the teaching efficiency. [0003] There is also a patent in the prior art about electronic blackboards for multimedia classrooms. For example, a Chinese patent with application number 2015210056874 discloses electronic blackboards, including displays, writable blackboards arranged on both sides of...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, it is easy to solve the problem that when the teacher stands in front of the desk, the body easily blocks the students' sight so that the students cannot see the content on the display; and when erasing the blackboard in the writable area, manual erasing is required, which improves the The labor intensity of the lecturer reduces the problem of teaching efficiency; the invention proposes an electronic blackboard for multimedia classrooms
