Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
It is clear, be fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Example is applied, based on the embodiments of the present invention, those of ordinary skill in the art institute without creative efforts
The every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1-Figure 3, the utility model embodiment provides a kind of English teaching multimedia-assisted teaching aid, including
Lectern 1 and the auxiliary device being arranged on lectern 1, auxiliary device is primarily to place projector and computer, in this way by projection
Instrument and computer separate, and reduce the area occupied to 1 desktop of lectern, and lectern desktop will not be significant so mixed and disorderly again.
Auxiliary device includes support device 2, the first supporting plate 3 and the second supporting plate 4, lower end and the lectern 1 of support device 2
Desktop be fixedly connected, the upper end of support device 2 is fixedly connected with horizontal first supporting plate 3 and the second horizontal supporting plate 4.Example
If support device 2 is support plate, support plate places vertically, and the lower end of support plate is fixedly connected with lectern desktop, support plate it is upper
End is fixedly installed horizontal the first supporting plate 3 and the second horizontal supporting plate 4, and the upper surface and second of the first supporting plate 3
The upper surface of supporting plate 4 flushes.Projector is placed on the first supporting plate of user 3, and notebook electricity is placed on the second supporting plate 4
Brain.
