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.
