Abstract

The utility model relates to an electronic sliding-type learning device for exercise-choosing, which is an electrified education toy which is suitable for multi-disciplinary intelligent training for children. The utility model comprises a plastic box, sliding keys, leaning drawing card, and a sound and light circuit. The utility model is characterized in that two sliding keys can respectively slide on a cardboard printed with a plurality of questions back and forth. The circuit can be switched and the sound and the light can be shown to indicate that the answer is right when the two sliding keys are on positions of the question and the corresponding answer, and otherwise, the sound and the light can not be shown to indicate that the answer is wrong.

Description

Electronic sliding-type learning device for exercise-choosing

The utility model relates to a kind of, uses two slide keys, changes the selected topic and answer, has the children's intelligence type audio-visual education programme device that acousto-optic shows.

At home in the market, intellectual service audio-visual education programme toy kind is few, what put goods on the market has a rotary shaft escape learner, learner is inserted in the choosing of scraps of paper hole, and computing machine shows learner by sign indicating number, and they are all playing positive role aspect the exploitation children's intelligence, but at learning content, selling price, aspects such as using method also all exist drawback separately.

The utility model will provide a kind of novel structure, slidingtype selected topic learning device.During use, only need two slide keys of operation, just can in the picture that is printed on numerous selected topics and answer, seek corresponding answer, if selection is correct, then have acousto-optic to show that this device can send eight kinds of sound equipments, to strengthen learning interest.

The utility model has outstanding feature, and (1) is owing to having adopted slidingtype selected topic scheme, so proposition is directly perceived, easy and simple to handle.(2) the study picture of printing because of separated time can be replaced, so learning content is expanded, relates to various fields such as mathematics, Chinese language, history, geography.(3) this device has adopted the corresponding contact on the slide key separated time contact wiring board, to be communicated with the method for trigger circuit, so manufacture craft is very simple, with low cost.

Below in conjunction with Fig. 1, Fig. 2 labor inner structure and principle of work.

Fig. 1 is a shape assumption diagram, it comprises main body plastic casing (1), two transparent slide keys (2) and (3) are arranged in the plastic casing, slide key slides in chute (4), (5), (6), the study picture (7) that can replace is arranged under the slide key, and separated time is tied up copper circuit board (8), (9) are fixed under the middle chute loam cake (10).

Fig. 2 is a cut-away view, and wherein Ic, BG, R, D power supply E and loudspeaker are formed the octave circuit interconnect pattern, eight contacts of Ic and negative supply respectively with tie up copper circuit board (8), (9) separated time is connected.The inner of slide key (2), (3) is fixed with elastic sheet metal (11), (12).(they are in and are communicated with the position in this example).

As Fig. 1, shown in Figure 2, slide key (2), (3) in chute, slide, when left side slide key (2) is slided a selected topic, in the time of for example on the 2+3 position, the elastic sheet metal (11) that its slide key (2) is inner, the contact, the 4th road that to tie up in the copper circuit board (8) is communicated with, if this moment is sliding on=5 position with the slide key (3) in left side, its inner elastic sheet metal (12) then, the contact, the 3rd road that will tie up in the copper circuit board (9) is communicated with, this moment Ic the five road trigger circuit closure, loudspeaker sends the machine gun sound, the glittering indication of diode D is selected correct.If a slide key is wherein arranged not at correspondence position, then trigger circuit are in off state, just do not have sound equipment and flash of light, select mistake with expression, need reselect.

Element is selected and is made:

Ic is a KD9562 octave integrated music sheet, also can select other musical film, BG is the 3DX201 transistor, R is 1/8W, 300K resistance, D is φ 3 light emitting diodes, loudspeaker are selected φ 50,8 Ω, 0.2W loudspeaker for use, power supply E selects for use No. 5 powered battery of 2 joints with reference to Fig. 1, select one of the sticking system of plastic plate plastic casing for use, wiring board (8), (9) can select for use the common copper coin of tiing up according to drawing making, slide key (2), (3) can select the colored transparent plastic production for use, it is slided freely, the elastic sheet metal of one end (11) in chute, (12) can select for use the sprung copper leather of φ 0.1 to do.It is contacted well with tiing up copper circuit board, select for use the presspaper separated time to draw the selected topic and answer, the selected topic requires corresponding one by one with two line contacts of tiing up on the copper circuit board with the correspondence position of answer.Picture relates to content: mathematics, Chinese language, geography, history etc.Quantity is made many, and its size can conveniently be replaced into it under slide key suitable.

After element is got all the ready, can connect according to Fig. 2, if weld errorless, once success, complete machine need not to adjust.

Claims (3)

1, a kind of children's intelligence type audio-visual education programme toy that is shown by acousto-optic is characterized in that:

A, use two slide keys (2), (3), change the selected topic and answer, the inner of slide key (2), (3) is fixed with elastic sheet metal (11), (12), and elastic sheet metal contacts with 8 contact separated times on tiing up copper circuit board (8), (9).

B, study picture 7 usefulness cardboards or slim plastic sheet are printed, and can be in slide key (2), (3) displacement down.

C, tie up copper circuit board (8), (9) are connected with the acousto-optic circuit separated time.

2, electronic toy according to claim 1 is characterized in that acousto-optic circuit adopts KD series acousto-optic integrated circuit.

3, electronic toy according to claim 1 is characterized in that learning picture (7) separated time and prints the selected topic and answer, and its correspondence position requires corresponding one by one with two line contacts of tiing up on copper circuit board (8), (9).
