Abstract

The utility model relates to an interesting teaching device for children. Graphic panels printed with different patterns, simple mathematical expressions, Chinese phonetic alphabets, and common Chinese characters are made into inserting pieces, and an on-off circuit panel arranged on the lower part of each inserting piece is printed according to corresponding binary encodes. The circuit can send out the signal display such as the music, the glitter, etc. through the encoding circuit and the decoding circuit after the inserting pieces are inserted into different plug sockets to indicate whether the answer is right. The utility model which is suitable for education such as intuitively learning to read by a way of pictures, Chinese phonetic alphabets, simple digital computation, etc. of the preschool children, pupils in grade one and pupils in grade two can be used both as an intelligence education tool for children and a toy.

Description

Interesting teaching device for children

A kind of children entertaining instructional device.

Existing children's intelligence development device belongs to two metal cushions to each jack more, represents by the break-make of circuit whether answer is correct.Because of the jack position of circuit is fixed, lack variation, intuitive and iconicity are all relatively poor.

The purpose of this utility model is intended to overcome above shortcoming, adopt the hyundai electronics coding and decoding circuit, enlarge variation range, improved reliability, vivider, more directly perceived, as know number, learn to read with the aid of pictures, the calculating of phonetic alphabet, plus-minus method etc. is as not, shows by acousto-optic automatically, reaches study and the double-deck purpose of amusement.

The utility model is to implement like this, all adopts 12 binary codings to encode each numeral, each width of cloth figure, each phonetic alphabet etc. in advance.As: the pattern coding of cat, dog, chicken is identical with the coding of phonetic alphabet mao, gou, ji and Chinese character cat, dog, chicken, is respectively 000011110000,000011110001,000011110010.The coding of numeral 10 also is the coding 000000001010 of 5+5,8+2,7+3,12-2,18-8,2 * 5,20 ÷ 2 etc.Coding utilizes two-sided copper clad plate to cooperate socket break-make ground connection and realizes.When carrying out digital computation, the coding 000000001010 of 8+2=10,0 correspondence position does not have Copper Foil, 1 correspondence position leaves Copper Foil and corresponding with Die for Reeds of Connector Jack, when inserting socket A, on Copper Foil on the plate and the socket the 2nd, 4, the contact of 7 copper sheets, make 2,4 pin ground connection, the coding integrated package IC1 that is connected with socket is input to decoding IC2 with this coding according to certain rules, if this moment, numerical value was that 10 slotting board is when being inserted into socket B, then send all identical with the coding and decoding that receives, this moment the IC2 output low level, trigger music integrated block IC 3, send through loudspeaker by the IC4 amplification, light emitting diode is at this moment constantly with music flashing, " √ " check mark pilot lamp L1 lamp is bright simultaneously, expression 8+2=10 calculates correct, otherwise, when being that any numeral 10 is inserted board (as 11 except that value, being encoded to 000000001011) when being inserted into the B socket, then transmission is different with the coding that receives, IC2 output this moment high level, music integrated block IC 3 is not worked, do not have sound to send, " * " wrong number pilot lamp L2 lights simultaneously, the expression miscount.So reach the correctness that " * ", " √ " pilot lamp L2, L1 indicate answer clearly by sound, light.Other is learnt to read with the aid of pictures, the principle of phonetic alphabet etc. is the same.

This device knowledge number is performed such:

First method: K1-K4 is that lamp is counted selector switch, when any switch connection, routine K1, K3 connects, D5, the D7 conducting, then five lamps of LED1-LED5 are bright, this moment IC1 the 1st, 3 pin are equivalent to ground connection, are encoded to 00000000101, if it is encoded to 00000000101 with digital 5() be inserted in the B socket, then IC1 is identical with the coding and decoding of IC2, the IC2 output low level triggers IC3 equally, amplifies through IC4, loudspeaker send musical sound, LED16-17 is luminous, and L1 is bright for " √ " check mark pilot lamp, and it is correct that number is known in expression, otherwise, insert any one number except that digital 5 and insert socket B, L2 is bright for " * " wrong number pilot lamp, represents to know to miscount by mistake.

Second method: K1-K4 is resetted, numeral is inserted board (in 15), and it is encoded to 000000001010 as 10() be inserted in the A socket, copper sheet 2,4 ground connection then, D6, D8 conducting, LED2-3, LED8-15 be bright 10 lamps altogether, that is to say that slotting numeral is that several (limit 15 is to include 15) then several lamps are bright.

More than two kinds of methods in conjunction with utilization, make the reversible utilization of thinking in images and abstract thinking, be easy to make children to set up the notion of numeral.

In addition, microphone can be inserted in the jack, amplify, teach and student's amusement usefulness for the teacher.

The utility model can be made large-scale (blackboard shape) and miniature (books are big) is applicable to kindergarten, primary grades and home-use respectively.

Claims (3)

1, a kind of children entertaining instructional device, it is characterized in that it be by be printed on various character learning patterns (or phonetic alphabet, simple mathematical formula, Chinese character etc.) and have by the corresponding contents binary coding circuit insert the utmost point and the coding circuit that is complementary with the coding circuit plate, decoding scheme, display circuit, power circuit constitutes.

2, children entertaining instructional device according to claim 1, the display circuit that it is characterized in that it is to be made of flasher circuit, music circuit, power amplification circuit.
