The utility model is characterized in that the upper part of the plastic plate is provided with addition, subtraction, multiplication and division mathematical formulas and selected answers; the lower part of the plastic plate is provided with variable formulas and labyrinths. A switch indication mechanism which is composed of a music integrated circuit shows the right or the wrong of selected results to cultivate the reflection and the judgment abilities of children. The utility model is an intelligent toy which integrates the functions of interest, entertainment, knowledge and intelligence development into one body.

Description

Children's electronic computer for learning

The utility model relates to a kind of children arithmetic puzzle, is specially children's electronic learning machine.

The most of interest of only paying attention to of existing toy for children has been ignored intelligence development, and the children intelligent toy that has is too dull again.

The utility model is fully being studied on the basis of child age feature and psychological characteristics at above-mentioned existing problems, and its purpose is to provide a kind of novel children intelligent toy.

Interesting, the recreational and multiple function of intelligence development that the utility model integrates, easy and simple to handle, hand brain and usefulness, intuitively interesting, the residence intelligence development is of value to children is implemented rudimentary maths initiation education and intelligence development among amusement is played.

The purpose of this utility model is achieved in that and is provided with addition subtraction multiplication and division mathematics formula and selective answer on the top of plate, be provided with variable formula, rechoning by the abacus mechanism and labyrinth in the bottom of plate, and by the switch indication mechanism that the music integrated circuit that matches is with it formed show selection result to mistake, and show, play out music simultaneously by display screen, cultivate children and think deeply judgement thereby reach.

Fig. 1 is a front view of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Fig. 3 is that circuit connection diagram is answered in formula choosing of the present utility model.

Fig. 4 is that 18 structural drawing are coiled in digital garden of the present utility model.

1-2 is described in detail the utility model below in conjunction with accompanying drawing.

The utility model is to be made of plastic plate 1, be provided with addition subtraction multiplication and division mathematics formula 3 and selective answer 12 on the top of plate 1, be provided with variable formula 7, rechoning by the abacus mechanism 19 and labyrinth 13 in the bottom of plate 1, and the switch that forms by the music integrated circuit 15 that matches with it shows machine Structure Selecting operation result to mistake, shown by photoelectric screens 2,4. Blank square to be selected 5 in the formula 3 and answer square 12 consist of by sheet metal, and blank metal square 5 to be selected passes through lead 14 connections with corresponding answer metal square 12. Variable formula 7 forms arbitrarily conversion formula mechanism by spiral button 6, operator slide block 8 and aobvious word hole 10 of digital garden dish 18, garden. Rechoning by the abacus mechanism 19 forms arbitrarily conversion formula by bead 11, operator slide block 8 and pearl groove 9. Music integrated circuit 15 is made of a music-integrating block CW, triode BG and two diodes 20 in parallel, two probes 21.

Embodiment 1: integrated package adopts CW9300 type glomeration, display screen 2,4 respectively by the back side be carved with hollow " to " word and animal constitute, loudspeaker 16 and miniature bulb 17 are housed in it, the eyes of personage's pattern 4 are connected with two light emitting diodes 20, music integrated circuit 15 with two conductive stylus 21 as switch, two conductive stylus 21 are drawn by 1 and 2 utmost points of music-integrating block respectively, 7 of resistance R and music-integrating block, 8 the two poles of the earth are connected, loudspeaker 16 are in parallel with two light emitting diodes 20, the base stage of transistor BG is connected with music-integrating block 3 utmost points, and 4 utmost points of collector and music-integrating block join.Variable formula 7 by three digital gardens spiral button 6, be printed on "+", "-", "=", "＜", "〉" the operator slide block 8 of symbol and apparent word hole 10 form arbitrarily conversion formula mechanism.Rechoning by the abacus mechanism forms arbitrarily conversion formula by four row's beads 11, three operator slide blocks 8 and pearl groove 9.

When two conductive stylus 21 short circuits, music integrated circuit 15 work, loudspeaker 16, diode 20 and miniature bulb 17 are all worked.Do when topic, operator's both hands are respectively held a conductive stylus 21, wherein the nib of a conductive stylus 21 is placed on the blank metal hand sheet 5 of the formula of doing, the nib of another conductive stylus 21 is placed on the sheet metal 12 of selected answer, if the choosing to, then two conductive stylus 21 phase short circuits, circuit be switched on, loudspeaker 16, miniature bulb 17 and light emitting diode 20 work, at this moment display screen 2 demonstrate " to " word, loudspeaker 16 are played out music, the eyes of personage's pattern 4 are glittering, if choosing is wrong, circuit disconnects, then there is not above-mentioned phenomenon.When using variable formula mechanism, as long as rotation number letter disk knob 6 and move and calculate symbol slide block 8 just can change arithmetic problem arbitrarily and practise.Rechoning by the abacus is partly moved bead 11 and formula symbol slide block 8 just can be known number and computing directly perceived along pearl groove 9, and can be used with variable formula mechanism.Labyrinth 13 is directly injection-moulded on 1 of the plate, and road is partly recessed, and obstacle is projection partly.
