Abstract
The utility model discloses a calculation trainer for a preschool child. A circuit board is fixed inside the casing of the trainer, the panel of the casing is respectively and fixedly provided with a loudspeaker which is connected with an analogue amplifying circuit of the circuit board, a liquid crystal display which is respectively connected with a microprocessor and a digital processor of the circuit board, and a number input keyboard which is connected with the digital processor from top to bottom. By inputting formula for repeated practice and comparison, the practice can be carried out at all times and places, the child does not need to wait to learn until the parent is free, the child repeats practicing to reach 100% accuracy and is willing to practice and compete with other children, the interest in studying math is improved, and teaching through lively activities is achieved.
Description
Technical field
The utility model relates to a kind of preprimary child and calculates exercising machine, belongs to the preschool education technical field.
Background technology
Usually the preprimary child learns to calculate Shi Yaoyou adult guidance, and operation result can not be corrected errors in the self check judgement, has so both taken adult's time, can not improve again the interest of children learn, and results of learning are bad.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of preprimary child to calculate exercising machine, by inputting formula in liquid crystal display, "=" key on the keypad automatically demonstrates the formula result and by comparing with the correct result that is stored in exercising machine inside, sends the prompt tone of " right " or " wrong " by loudspeaker; Full 30 problems of exercise, and accuracy is when being 100%, and loudspeaker also can be played out beautiful child music children are rewarded.
The technical scheme that its technical matters that solves the utility model adopts is: the preprimary child calculates exercising machine, and it is comprised of casing, circuit board, loudspeaker, liquid crystal display, digital input keyboard, power switch.Be fixed with circuit board in casing, on the panel of casing, be fixed with respectively from top to bottom loudspeaker, loudspeaker is connected with the analog amplify circuit of circuit board; Be fixed with liquid crystal display, liquid crystal display is connected with digital processing unit with the microprocessor of circuit board respectively; Be fixed with digital input keyboard, digital input keyboard is connected with digital processing unit; Be fixed with power switch, power switch is connected with circuit board, power supply respectively.Described circuit board is comprised of digital processing unit, microprocessor, storer, dynamic storage, ROM (read-only memory), clock circuit, analog amplify circuit, D/A converting circuit.Analog amplify circuit is connected with microprocessor by D/A converting circuit; Digital processing unit is connected with microprocessor by storer; Dynamic storage, ROM (read-only memory), clock circuit are connected with microprocessor respectively.
The beneficial effects of the utility model are: by repeating and comparison of input formula, can practise whenever and wherever possible, just can learn in the time of need not waiting the adult free, and can repeatedly practise in order to obtain 100% accuracy child, and be ready to practise together, compete with child, improved the interest of learning mathematics, accomplished to teach through lively activities.This apparatus structure is simple, adopts lithium battery power supply, and is small and exquisite, easy to use.
