Abstract
The utility model provides a blackboard for Chinese teaching. The blackboard consists of luminous strips, a blackboard and a plurality of light emitting diodes arranged in the luminous strips, wherein the luminous strips are embedded in the blackboard in parallel; and the electrically connected light emitting diodes in the luminous strips are connected in series with a tandem switch and a regulation knob. Four Pinyin luminous strips are transversely arranged on the blackboard, the brightness is controlled through the knob, the blackboard is simple in structure and convenient to use, and the Pinyin lines can be rapidly displayed on the blackboard, so that the working strength of teachers is reduced, and the learning interest of students is improved; and therefore, the teaching quality and efficiency are improved.
Description
Technical field
The utility model relates to the language teaching field of tool, particularly a kind of blackboard for Chinese teaching.
Background technology
In existing life, often need the faculty to draw the phonetic line in language teaching work on blackboard, owing to there is no professional teaching aid, the faculty can't draw the phonetic line of standard, even utilize instrument to draw the phonetic line, workload is not little, the most important thing is to waste the most valuable opportunity of giving lessons in a class, can not reach best teaching efficiency, make student's visual fatigue lose learning interest, this has brought great trouble to teaching.How design innovation go out easy to operate, novel visual good language teaching instrument, this is the problem that we need solution badly.
The utility model content
In order to overcome the defective of prior art, the utility model provides following technical scheme:
The utility model provides a kind of blackboard for Chinese teaching, formed by light-emitting section, blackboard and some light emitting diodes of being arranged in light-emitting section, light-emitting section is parallel to each other and embeds in blackboard, and the interior some light emitting diodes that electrically connect of light-emitting section are tandem tap and adjusting knob also.
The utility model further improves and is: the light-emitting area of light-emitting section is concordant with blackboard.
The utility model further improves and is: the switch of light-emitting section and adjusting knob are installed in blackboard lower-left side.
The utility model further improves and is: light-emitting section is rigid transparent material; Light emitting diode can send various photochromic.
The beneficial effects of the utility model are: the utility model adopts and laterally be provided with four phonetic light-emitting sections on blackboard, and control brightness by knob, it is simple in structure, easy to use, can show fast the phonetic line on blackboard, thereby reduce teacher's working strength, improve student's learning interest, thereby improved quality of instruction and efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit structure schematic diagram.
Number in the figure is:
1, light-emitting section; 2, blackboard; 3, light emitting diode; 4, switch; 5, adjusting knob.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
As shown in Figure 1, 2, the blackboard for Chinese teaching that the utility model provides, formed by light-emitting section 1, blackboard 2 and some light emitting diodes 3 of being arranged in light-emitting section 1, described four light-emitting sections 1 are parallel to each other and embed in blackboard 2, and the interior some light emitting diodes that electrically connect 3 of described every light-emitting section 1 are gone back tandem tap 4 and adjusting knob 5.
Described every light-emitting section 1 light-emitting area is concordant with blackboard 2.
The switch 4 of described every light-emitting section 1 and adjusting knob 5 are installed in blackboard 2 lower-left sides.
Described light-emitting section 1 is rigid transparent material; Described light emitting diode 3 can send various photochromic.
When the utility model carries out Pinyin teaching, the switch 4 of every light-emitting section 1 is opened, then according to the dark intensity of light of each classroom light, regulated adjusting knob 5, make it reach best display effect and get final product.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
