10' the back that is in series is in parallel, the channeling switch, and variable connector and music integrated block IC, the 3V power supply, indicator lamp I links to each other, and music integrated block IC is in parallel with indicator lamp I, and the music integrated block IC output links to each other with loudspeaker (7).
Children do a sum orally exercise game machine shape as shown in Figure 1, front face area is similar to textbook, has 10 with 70 of interior plus-minus verbal exercise cards, verbal exercise card shape such as Fig. 2, the subject card trough (1) of any a slice topic card from this machine inserted, and then subject window (2) is gone up and one verbal exercise occurred.Children think that it is several answering, just lift indicating on this digital answer push-buttom switch (4), if answer is correct, then indicator lamp (3) is luminous, and sends one section music from speaker hole (5) lining, and is if answer is incorrect, then unglazed also noiseless.
With reference to children's exercise game machine circuit diagram accompanying drawing 3 of doing a sum orally, two groups of switches are arranged in the circuit diagram, one group is the switch by the topic card control, title topic card power switch group is as K
1', K
2' ... K
10', totally 10, another group is lifted answer for children and is used, and claims the answer switches set, as K
1, K
2K
10, also totally 10.From circuit diagram, as can be seen, have only the switch of two same-codes in two groups of switches closed simultaneously, could connect power supply, make indicator lamp I luminous, music integrated block IC work, loudspeaker (7) broadcasts music.
10 switches of topic card power switch group all are normally closed switch, and by circular hole (6) control on the topic card, 10 have 70 problems (only get 4+2 in 4+2,2+4 two topics, other analogue is handled equally) with interior addition and subtraction, and answer has 1,2,3 ... 10, totally 10.A circular hole (6) is opened in the verbal exercise card below, the topic card that answer is different, and the position of circular hole is also different.Be that 3 topic card (2+1,4-1,5-2,6-3,7-4,8-5,9-6) is an example with answer now, circular hole positions of these topic cards are: after the topic card inserts this machine, just in time at topic card power switch K
3' the contact in the middle of, can make K
3' still closed, other switch in the topic card power switch group is then because of being subjected to inscribing the obstruct contact separation of card.Therefore, only taking the answer push-buttom switch that indicates number 3 off is K
3, could connect power supply, realize foregoing function.Same principle is adopted in other topic card circular hole position.
Children's exercise game machine of doing a sum orally can all be expanded as 18 to the switch of topic card power switch group and answer switches set, can calculate 20 like this with interior plus-minus mental arithmetic, totally 126 topics.If this machine increases volume, then can be used as the teaching aid that kindergarten and first grade of primary school teacher use.
When children practise doing a sum orally, can oneself learn whether answer is correct, thereby can cultivate self-learning ability; Because have indicator lamp and music to show, can excite learning interest, this game machine is easy to use, and is simple in structure, cheap.
The model of music integrated block IC can be used HFC9300, and it is in parallel with indicator lamp I, then works simultaneously after promptly connecting power supply.The music-integrating block of this model has 7 pin, 1 pin with join with the positive pole of power supply and an end of loudspeaker 7 again after 2 pin link to each other, 3 pin join with 7 the other end of raising one's voice, and an end of 5 pin and variable connector links to each other (the closed circuit power cathode of then connecting of switch), and 4,6,7 pin need not.
The material plastic sheet of verbal exercise card, the plastics of using as the student backing plate that writes.
About 20 with interior addition and subtraction verbal exercise, China's primary school math teaching outline and primary school mathematics textbook all are meant two one digit number additions and corresponding subtraction, as 8+7=15,15-7=8,15-8=7 etc., therefore maximum total is 18(9+9=18), minimum total is 1.(10+9=19,10+10=20,6-6=0 etc., textbook is not listed it in 20 with in the interior addition and subtraction table.) in other words, 20 answers with interior addition and subtraction mental arithmetic have 1,2,3 ... 18, totally 18, so the do a sum orally exercise topic card power switch of game machine and the switch of answer switches set of children all expand as 18, just can calculate 20 and do a sum orally with interior plus-minus.
