Problems solved by technology

However, because the projector requires very low indoor brightness, it is impossible to write and read on the blackboard. If the light and dark environments are switched alternately, it will not only take time and trouble, but also distract the attention of teachers and students and affect the teaching effect.
Third, multimedia projectors are expensive and have short bulb life. If they are used in school classrooms, they must meet the requirements of high frequency of use, diverse teaching content, and many people. Therefore, it is necessary to ensure the integrity and safety of these equipment. Requires a lot of maintenance and management investment
Fourth, the multimedia projection teaching system takes up a lot of space, the projection display effect is greatly affected by the equipment status and environment, and it is difficult to obtain high-definition picture quality, and the TV reception and music reverberation entertainment functions are limited
[0006] To sum up, due to the existence of existing technologies and equipment: scattered equipment, inconvenient management and use, and difficulty in collaborative use of multimedia and blackboard writing

Embodiment 1

[0024] The specific embodiment of the present invention: four parts are made up altogether, namely i. translation opening and closing type blackboard; ii. flat panel display multimedia playback system; iii. configure a wireless keyboard). Now explain item by item:

[0025] i. Translational opening and closing blackboard

[0026] figure 1It is a schematic diagram of the structure of the translational opening and closing type blackboard: the load-bearing top plate 1 is a high-strength alloy profile, and is fixed to the wall 2 by expansion screws. The blackboards 3 on the left and right sides of the same size adopt a green paint board with length × height = 1.5m × 1m plus a high-strength swimming aluminum alloy frame, and adopt a double support structure of upper and lower guide rails to ensure smooth movement. The top is equipped with a rolling pulley kit 4, and the pulley and the blackboard are connected to the upper guide rail 5 of the top plate and can slide smoothly. The...

Embodiment 2

[0039] The difference from Example 1 is that the display uses a 72-inch PDP plasma display. The plasma display has the characteristics of high brightness, rich colors, wide viewing angle, and hard screen. Due to the large screen size, it can meet the needs of larger environments: such as lecture halls, etc. , see the structure diagram of this example Figure 9 .

[0040] The blackboard is composed of two 2m×1.2m blackboards. The actual width of the PDP display is 1.6m×1.2m. The height of the display is the same as that of the blackboard, so the display is in the middle of the blackboard, and the upper and lower borders are consistent with the upper and lower borders of the blackboard. In Embodiment 1, the circuit board in the control cabinet is moved to the rear of the blackboard. The USB interface and the control switch and knob of the wireless amplifier are placed at the lower part of the bottom plate.

Abstract

The invention discloses audio-visual teaching equipment and in particular discloses a large screen flat-panel display and multimedia integrated combined blackboard. The combined blackboard comprises the following four parts: a translational open-close type blackboard, a large screen flat-panel display and multimedia player system, a blackboard frame type wireless speaker amplifying system and a photoelectric wireless mouse with the function of a pointer. The combined blackboard is the third generation teaching blackboard which appears for the first time and is based on combination of the flat-panel display and the common blackboard, following the first generation common writing blackboards and the second generation multimedia projector electronic whiteboards. Having the technology, performance, cost, use and maintenance advantages, the combined blackboard has high application and popularization value and large market space. The combined blackboard can realize the effect of synchronously carrying out multimedia player teaching and common blackboard writing teaching in bright classrooms.

Description

Technical field: [0001] The invention belongs to an audio-visual teaching equipment, in particular to an integrated large-screen flat-panel display multimedia combined blackboard. Background technique: [0002] At present, in classrooms, conference rooms, and lecture halls, the teaching equipment used for teaching is an ordinary blackboard (a generalized blackboard is a general term for teaching boards with repeated erasing functions, which includes blackboards, green boards, whiteboards, etc.) , the "blackboard" mentioned in this article refers to this type of teaching board), and there is another type of multimedia teaching system that uses a computer + video projector. The ordinary blackboard has the characteristics of direct communication, simple and smooth, and low cost; while the multimedia projection system has the characteristics of good organization, strong intuition, and vivid media playback. As a supplement to the blackboard writing, it has indeed played an import...
