Description

A kind of infant reading plate with memory timer

Technical field

It the utility model is related to childhood teaching field of tool, and in particular to a kind of infant reading with memory timer Plate.

Background technology

Literacy board is a kind of educational aid for for child recognize character learning.Existing infant reading plate is typically arranged to The structure for being easy to word cards to plug, the mode used is that the word cards for needing to show child are put into Literacy board, dew Go out the part of Chinese character.This Literacy board has a defect, exactly have ignored the memory regulation of infant reading, according to German psychology This great research of family Chinese mugwort guest finds that man memory content is to follow certain rule, and first is forgotten peak after study 20 minutes or so, it was 58.2% or so that memory, which retains ratio, and it is 1 hour or so that second, which is forgotten peak, and memory retains ratio and is 44.8 or so.Existing Literacy board can not help child to overcome forgetting peak, so as to cause child's repetition learning, but repeatedly The result of forgetting.

The content of the invention

The purpose of this utility model is in order to solve existing Literacy board child can not to be helped to overcome forgetting peak, causes children Youngster's repetition learning new word, but the shortcomings that can forget repeatedly, and propose a kind of infant reading plate with memory timer.

A kind of infant reading plate with memory timer, the infant reading plate are the cuboid with six faces, its In the first face be engraved structure, the second face has slot, and the slot is used to insert word cards, so that the word of word cards Part can be shown by the engraved structure；Timer circuit is integrated with 3rd face, the timer circuit includes First MX107 timing circuits, the 2nd MX107 timing circuits, inter-lock circuit, the first timing weight triggers circuit, the second timing Weight triggers circuit, first switch circuit and second switch circuit；Wherein, the first MX107 circuits and the 2nd MX107 timing circuits Output end be connected with the input of inter-lock circuit；The tie point and first of first output end of inter-lock circuit The input connection of timing weight triggers circuit, the second branch road are connected with first switch circuit；Second output of inter-lock circuit The tie point at end is connected with the input of the second timing weight triggers circuit, and the second branch road is connected with second switch circuit；First The output end of timing weight triggers circuit is connected with the input of the 2nd MX107 timing circuits；Second timing weighs the defeated of triggers circuit Go out end to be connected with the input of the first MX107 timing circuits；First surface have make timer start the beginning button of timing with And the replacement button for being reset timer；First face has the first loudspeaker and the second loudspeaker, and described first raises one's voice Device is connected with the OUT pins of the first MX107 timing circuits, second loudspeaker and the 2nd MX107 timing circuits OUT pins connection, when the OUT pins of the first MX107 timing circuits are low level by high level saltus step, described first raises one's voice Device sends sound, when the OUT pins of the 2nd MX107 timing circuits are low level by high level saltus step, second loudspeaker Send sound.

The beneficial effects of the utility model are：1st, application method is similar with existing Literacy board, is all first by word cards It is put into character learning plate framework, it is not necessary to which user relearns occupation mode, the less burden of children education practitioner；2nd, it is put into knowledge It after word card, can as needed be timed, can set 20 minutes, 1 hour or other meet the time point for forgeing peak, So teacher can be reminded to help child to be reviewed again at these time points, improve the memorability of child, improve character learning effect Rate；3rd, the circuit components cost used is very low, occupies little space, easy to spread and popularization.4th, circuit structure is circulated using 2 tunnels Regularly, alternately timing, each timer timing different sound can be then sent by different loudspeakers, It is high to represent that the first time that carry out 20 minutes is forgotten when more more complicated functions can be provided, such as sending first kind sound Peak is reviewed, and represents to forget peak review second that carry out 1 hour when sending the second class sound, so within one device Not needing any adjustment to set just can complete to review twice, simple to operate, and complete function.
