Multimedia device for Chinese teaching

Abstract

The invention discloses a multimedia device for Chinese teaching, which comprises a teaching desk, a display screen is mounted on the front surface of the teaching desk, a mounting groove is formed in the front surface of the teaching desk, a sliding chamber is slidably connected to the inner side wall of the mounting groove, a sealing door is rotatably connected to the top of the sliding chamber through a rotating shaft, a torsional spring is arranged on the rotating shaft, a motor cavity is formed in the sliding chamber, the inner side wall of the motor cavity is fixedly connected with a driving motor, and the output end of the driving motor is fixedly connected with a bidirectional lead screw. A projector is arranged in the teaching desk, so that the projector can project a blackboard at a closer position, Chinese teaching is carried out by projecting an image on one side, the situation that blackboard writing is generally carried out needs to be explained that the whole sliding chamber can slide on the inner side wall of the mounting groove, the distance between the projector and the blackboard can be freely adjusted, and the distance is adjusted according to the viewing standard of students.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a multimedia device for Chinese teaching. Background technique [0002] Chinese (is the language of China, especially the language of the Han nationality. In the cultural circle of Chinese characters and overseas Chinese communities, Chinese is also called Chinese and Chinese. At the same time, Chinese is also one of the six working languages ​​of the United Nations. It can be seen from this , Chinese, like English, has already occupied an important position in the world. [0003] The current Chinese teaching multimedia devices generally use a projector to be placed above the middle of the classroom, and then project images from the air for teaching. On the one hand, the current projection device in the air is in a suspended state, and there are no advantageous protection measures, so that the projection device may be damaged by impact At the same time, most of the current p...

Problems solved by technology

[0003] The current Chinese teaching multimedia devices generally use a projector to be placed above the middle of the classroom, and then project images from the air for teaching. On the one hand, the current projection device in the air is in a suspended state, and there are no advantageous protection measures, so that the projection device may be damaged by impact At the same time, most of the current projection devices are projected on the entire blackboard, occupying a large space, which is not conducive to writing on the blackboard while projecting the projected image. On the other hand, the current projection equipment lens is exposed to the air for a long time, and the residual dust will Adhering to the lens is not conducive to the generation of images. Therefore, a multimedia device for Chinese teaching is proposed.
