Problems solved by technology

[0005] The invention provides a music appreciation teaching board. On the one hand, it solves the problem that the stave structure in the existing music teaching board is fixed. Generally, it can only be used as a stave writing on the surface of the teaching board. The purpose is single and the practicability is not strong; on the other hand, Solve the problem that there is no projection writing board suitable for music appreciation teaching in the existing teaching board

Embodiment 1

[0028] Such as figure 1 , 2 Shown in and 5, a kind of music appreciation teaching board comprises base 7, teaching board main body, controller 3 and note magnetic button 23, and the bottom of base 7 is evenly equipped with four groups of universal wheels 8, each group of universal wheels 8 Both are equipped with brake devices, and the upper front side of the base 7 is provided with two groups of hydraulic lifting devices 6 at intervals along the horizontal direction. At the bottom of both sides, the support seat 4 is an inverted trapezoid. The main body of the teaching board is composed of a magnetic staff board 2 and a frame 1. The magnetic staff board 2 is installed in the frame 1. The magnetic staff board 2 includes a translucent whiteboard layer 12, a light source layer 13, a magnetic material layer 18, a bottom board layer 19 and a blackboard layer 20 . The light source layer 13 is provided with a reflective device, which reflects the light emitted by the light source,...

Embodiment 2

[0036] Such as image 3 As shown, it is basically the same as Embodiment 1, and the difference is that the reflective device is made up of an arc mirror 21 and two plane mirrors 15, the arc mirror 21 is in contact with the magnetic material layer 18, and one end of the two plane mirrors 15 is connected to the magnetic material layer 18. The curved reflector 21 is fixed together, the other ends of the two plane mirrors 15 are in contact with the translucent white board layer 12, and an opening 16 of 1-5 mm is arranged between the two plane mirrors 15 . Adopting the curved reflector 21 can make the light-gathering effect better.

Embodiment 3

[0038] Such as Figure 4 As shown, it is basically the same as Embodiment 1, the difference is that: the surface of the translucent whiteboard layer 12 is also provided with a writing projection layer 22 . Ordinary translucent whiteboards have problems such as unclear projection and light spots when used as a projection screen. The writing projection layer of the present invention is obtained by the following steps: in parts by weight, 30 parts of methacrylate (Laromer LR 8887 of BASF), 20 parts of acrylate oligomers (Laromer UA 9031 of BASF), polyester acrylic acid 10 parts of resin, 20 parts of acrylate crosslinking monomer (SR 4540 from Sartomer), 8 parts of fumed silica, 7 parts of rutile titanium dioxide, 4 parts of photoinitiator (BASF IRGACURE 2959), 3 parts of dodecyl 0.5 part of ethoxysilane, 0.4 part of octadecyl triethoxy, 0.1 part of dispersant EFKA-4050, then mix them, add solvent ethyl acetate to make the powder in the paint 30%, and then paint Clothed on a tra...

Abstract

The invention relates to a music appreciation teaching board which comprises a base, a teaching board body, a controller, and magnetic note buckles. The teaching board body is composed of a magnetic staff board and a frame. The magnetic staff board, which is installed in the frame, comprises a semi-transparent white board layer, a light source layer, a magnetic material layer, a bottom board layer, and a black board layer. The light source layer is equipped with a light reflecting device which reflects light emitted by a light source and makes the light form a staff with the width being 1-5mm on the semi-transparent white board layer. A hydraulic lifting device and the light source are connected with the controller. The music appreciation teaching board of the invention is switched on when in use, which enables the light emitted by the light source to form a staff on the semi-transparent white board. Then, the magnetic note buckles are placed at proper positions, and staff writing is completed. The music appreciation teaching board is simple, and can be used repeatedly.

Description

technical field [0001] The invention relates to a music teaching teaching aid, in particular to a music appreciation teaching board. Background technique [0002] As we all know, music class is an important course for aesthetic education for students. In music teaching, music textbooks are often used. If teachers need to use staves in teaching, they need to draw them on the blackboard. The staves drawn with chalk cannot be reused. , to increase the workload of teachers, especially when it is necessary to examine the memory of students' musical notes, it is necessary to repeat the above-mentioned process of drawing staves. The improvement of the effect. Some existing teaching boards are directly placed on the ground through brackets, which makes it difficult to move the teaching boards. At the same time, the height of the existing teaching boards generally cannot be adjusted, or the adjustment is more troublesome. When the teacher temporarily replaces Sometimes, it often ta...
