The English letter learning machine is characterized in that a card reading cavity and a card storage cavity are formed on the side face of a shell; a plurality of infrared emission lamps and a plurality of infrared receivers which are arranged at equal intervals are fixed at the end of the card reading cavity; the English letter learning machine also comprises a plurality of letter cards; an encoding hole is formed in each letter card; an infrared emission and receiving conversion circuit, an encoding circuit and an MCS51 singlechip with a memory are sequentially fixed in the shell; the video signal output end, the audio signal output end and a control signal output end of the singlechip are respectively connected with a video output circuit, an audio output circuit and a timed reminding circuit; and the output end of the video output circuit is connected to the signal input end of a display screen. By using the learning machine, a user can select cards to be learned according to a requirement; and furthermore, the English letter learning machine is very low in manufacturing cost, so that the English letter learning machine is easy to popularize and apply among English learners.

Description

A kind of English word learning device

Technical field

The utility model relates to a kind of appurtenance that is used for English word learning.

Background technology

At present, for improving the learning efficiency of student to English word, occurred multiple auxiliary word schooling apparatus on the market, wherein, the English word learning device of microcomputer type receives liking of students most.But, although this microcomputer English word learning device can be realized a lot of functions, because the internal electric element of its selection is too expensive, make selling price high always, therefore, fail in the middle of numerous English learners, to apply.

Summary of the invention

In order to solve the prior art problem that provides in the background technology, the utility model provides a kind of English word learning device, and this kind learner is cheap for manufacturing cost, and has multiple auxiliary function of carrying out English word learning, has advantages of high practicability.

The technical scheme of the utility model is: this kind English word learning device, comprise housing, and on the surface of said housing, be fixed with display screen, button and loudspeaker; The side of said housing has Card Reader chamber and card storage chamber, is fixed with infrared light transmitting lamp and infrared receiver that some equidistant intervals distribute in the end in Card Reader chamber; Said word learner also comprises the plurality of words card, has notch on every word card; Be fixed with infrared emission and the MCS51 single-chip microcomputer that receives change-over circuit, coding circuit and have storer in the said housing successively, video, audio frequency and the control signal output ends of said single-chip microcomputer respectively correspondence be connected with video output circuit, audio output circuit and alert circuit regularly; The output terminal of said video output circuit is connected to the signal input part of display screen; The output terminal of said audio output circuit and timing alert circuit is connected to the signal input part of loudspeaker; The signal input part of said button is connected to the signal input end of MCS51 single-chip microcomputer, and the signal end of said infrared light transmitting lamp and infrared receiver is connected respectively to infrared emission and the respective signal output, the input end that receive change-over circuit.

In addition; In order to make the memory contents in the word learner renewable; Can on said word card, be fixed with erasable chip; Internal fixation has the chip read port that matches with said erasable chip in said Card Reader chamber, and the data that said chip read port reads read circuit through chip and are passed to the corresponding stored data input pin on the MCS51 single-chip microcomputer.

The utlity model has following beneficial effect: utilize this kind English word learning device, the student can be placed on the word card in the card storage chamber according to the content choice of oneself wanting to learn.Behind word card insertion Card Reader chamber; According to the different position of notch of being opened on the word card, the infrared receiver of some positions just can receive the light that corresponding infrared light transmitting lamp is sent, thereby accomplishes the addressing process through exporting to single-chip microcomputer behind the coding circuit coding; Afterwards; Single-chip microcomputer can find corresponding video or audio content to output to display screen or loudspeaker in storer according to the address code of receiving, thereby accomplishes the study to the part English word.This kind of English word learning device manufacturing cost is extremely low, is no more than 40 yuans, and the user can select learning content flexibly, and is very convenient and practical.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, this kind English word learning device comprises housing 1, wherein, is fixed with display screen 4, button 3 and loudspeaker 5 on the surface of said housing 1; The side of said housing 1 has Card Reader chamber 9 and card storage chamber 8, is fixed with infrared light transmitting lamp 6 and infrared receiver 7 that some equidistant intervals distribute in the end in Card Reader chamber 9; Said word learner also comprises plurality of words card 10, and is as shown in Figure 2, has notch 11 on every word card 10.As shown in Figure 3; Be fixed with infrared emission and the MCS51 single-chip microcomputer that receives change-over circuit, coding circuit and have storer in the said housing 1 successively, video, audio frequency and the control signal output ends of said single-chip microcomputer respectively correspondence be connected with video output circuit, audio output circuit and alert circuit regularly; The output terminal of said video output circuit is connected to the signal input part of display screen 4; The output terminal of said audio output circuit and timing alert circuit is connected to the signal input part of loudspeaker 5; The signal input part of said button 3 is connected to the signal input end of MCS51 single-chip microcomputer, and the signal end of said infrared light transmitting lamp 6 and infrared receiver 7 is connected respectively to infrared emission and the respective signal output, the input end that receive change-over circuit.

In addition; In order to make the memory contents in the word learner renewable; Can on said word card 10, be fixed with erasable chip; 9 internal fixation have the chip read port that matches with said erasable chip in said Card Reader chamber, and the data that said chip read port reads read circuit through chip and are passed to the corresponding stored data input pin on the MCS51 single-chip microcomputer.Like this, when the partial content in the single-chip microcomputer storer has been learnt to finish, can new video, audio file be injected simultaneously with former memory contents deletion through the chip of word card end.

This kind of word learner in use, energized at first, pushing button starts working single-chip microcomputer; Behind word card insertion Card Reader chamber; According to the different position of notch of being opened on the word card, the infrared receiver of some positions just can receive the light that corresponding infrared light transmitting lamp is sent, thereby accomplishes the addressing process through exporting to single-chip microcomputer behind the coding circuit coding; Afterwards; Single-chip microcomputer can find corresponding video or audio content to output to display screen or loudspeaker in storer according to the address code of receiving, thereby accomplishes the study to the part English word.
