Description
The utility model relates to a kind of blackboard for education of band spectrum line, is particularly useful for music and foreign language teaching, belongs to teaching aid.
It is to paint the spectral line that draws mostly that present school carries out the used staff blackboard of music teaching.The shortcoming of this blackboard is to be difficult to write, and paint easily comes off, and can only be special-purpose.
It is that blackboard, the spectral line of the band spectrum line of one only shows when needed that the purpose of this utility model is to provide a kind of common teaching and music teaching of collecting, to realize a blackboard multiple use, convenient teaching.
The technical solution of the utility model is to realize like this, the blackboard for education of band spectrum line is made up of plate face, sheet frame, liner plate, blackboard panel is for engraving the dark frosted glass that prints off spectral line behind, between plate face and the liner plate light source is housed, mirror frosted blackboard spectral line by light, can between plate face and liner plate, not be equipped with opposite and the movable liner plate of obvious contrast is arranged if light source is not installed, foil the spectral line of frosted blackboard by moving up and down movable liner plate with blackboard spectral line striped.
Adopt blackboard for education of the present utility model, when music teaching or foreign language teaching, make the blackboard front show spectral line clearly by light or lining version, do special blackboard, when common teaching, by closing light or adjustment activity lining version spectral line is disappeared, make general blackboard and use, bring great convenience to teaching.
Now be described with reference to the accompanying drawings embodiment of the present utility model:
Fig. 1 is the blackboard for education front view of band spectrum line.
Among the figure:
1, frosted glass plate face.
