Abstract

The utility model discloses a device for studying Chinese phonetic alphabets, comprising a circuit part in a machine shell and a plurality of phonetic cards (1) marked with different Chinese alphabetic characters and tutoring figures. The phonetic cards are arranged outside the machine shell. A circuit is composed of the integrated circuit IC of the Chinese phonetic alphabets, a loud-speaker OY, a transistor BG, a resistor R, and batteries E. When the device for studying Chinese phonetic alphabets is used, the phonetic cards are inserted into the machine shell. The two end heads of a short guide wire (2) for triggering pronunciation on the card are respectively contacted with the triggering feet of a certain row of IC and the triggering feet of a certain range. Corresponding phonetic signals can be triggered out. In addition, the loud-speaker OY can sound. The utility model has the advantages of study and recreation in a whole, simple structure and low cost. Students can be effectively guided for learning and memorizing the Chinese phonetic alphabets through the device for studying the Chinese phonetic alphabets.

Description

Apparatus for studying Chinese Phonetics

The utility model relates to and a kind of teaching material is given to listen the electricity operation teaching aid of demonstration, specifically is meant a kind of pinyin learning machine.

Learning Chinese phonetic is a very withered hot-tempered thing, and the Language Teacher of many primary schools and parents of student's reflection: it is half-hearted that children learn phonetic, just learned and forgotten, and do not remember or the like.Trace it to its cause and be: memorize mechanically, have no interest, most of in addition again head of a family is that phonetic is blind, can't the accurate instruction child.And existing Chinese phonetic card of teaching child's study and Chinese phonetic alphabet building blocks and so on also are difficult to arouse children's interest.For this reason, suburb, county and rural school that relevant department, primary school, kindergarten, especially qualified teachers' strength very lack, all urgent wish to have a kind ofly collect study and amusement is the machine of the pinyin learning efficiently appearance of one.

The purpose of this utility model is to provide the pinyin learning machine of a kind of energy instruction of papil in conjunction with the picture and text orthoepy.

Below in conjunction with drawings and Examples the utility model is made detailed explanation.

Fig. 1 is the electrical schematic diagram of the circuit part in the utility model casing;

Fig. 2 is one a structural representation in the outer Pinyin card of the utility model casing.

Referring to Fig. 1 and Fig. 2, solution of the present utility model is as follows.It comprises the circuit part and several outer Pinyin cards (1) that indicate different Chinese alphabetic writings and teach figure of casing that is contained in the casing, its circuit part is by Chinese phonetic alphabet integrated circuit (IC), loudspeaker DY, triode BG, resistance R and battery E form, after being connected in a bit, one end of the positive pole of battery E and loudspeaker DY and resistance R joins with a power supply input pin of Chinese phonetic alphabet integrated circuit (IC) again, another power supply input pin of the other end of resistance R and Chinese phonetic alphabet integrated circuit (IC) joins, the collector C of the other end of loudspeaker DY and triode BG joins, the negative pole of the emitter e of triode BG and battery E is held with being linked to be, and link to each other with the grounding leg of Chinese phonetic alphabet integrated circuit (IC), the base stage b of the drive output of Chinese phonetic alphabet integrated circuit (IC) and triode BG joins, and Chinese phonetic alphabet integrated circuit (IC) also has, and several row trigger pin and several row trigger pin, also be fixed with respectively and trigger pronunciation short circuit lead (2) at the edge of several Pinyin cards (1), the distance that two terminations of short circuit lead (2) are gone up the present position and are separated by at Pinyin card (1) is because of the difference difference of Pinyin card (1).

The utility model with said structure is when concrete the use, Pinyin card (1) is inserted casing, two terminations of the triggering pronunciation short circuit lead (2) on the Pinyin card (1) are contacted with a certain pin that row trigger in the pin with a certain pin that the row of Chinese phonetic alphabet integrated circuit (IC) triggers in the pin respectively, can trigger out the corresponding phonetic signal that designs, and give triode BG from the driving output pin of IC and amplify, promote loudspeaker DY again and send predetermined phonetic.For different Pinyin cards (1), triggering two terminations of pronunciation short circuit lead (2) upward also designs inequality with the distance of being separated by in the present position at Pinyin card (1), therefore can be on request trigger pin and row with different row respectively and trigger pin and contact, thereby trigger the different Chinese phonetic alphabet.

In Fig. 1 embodiment, company limited's production of the Chinese phonetic alphabet integrated circuit (IC) employing No. 23 good roc electronics in Jianshe Road, China Shenzhen city (Shenzhen) and the model that can obtain on market are the extensive language integrated circuit of MSS2801, its row triggers pin and is designed to 7, promptly from the 1st pin ∽ the 7th pin, its row trigger pin and are designed to 8, promptly from the 17th pin ∽ the 24th pin, so the individual different Chinese phonetic alphabet of 7 * 8=56 that sends capable of being combined supplies 56 external adapteds of Pinyin card.Row triggering pin and row trigger pin also can be designed to other quantity, and the internal circuit of Chinese phonetic alphabet integrated circuit (IC) composition also should change thereupon certainly.The 8th pin among Fig. 1 is for driving output pin, and the 11st pin and the 12nd pin are the power supply input pin.DY should adopt Microspeaker, is beneficial to the miniaturization of complete machine.The shell of machine should be exquisite as far as possible.Battery E adopts 3V.

Referring to Fig. 2, Pinyin card (1) adopt cardboard, plank, printed board all can, trigger pronunciation short circuit lead (2) and can adopt plain conductor or utilize Copper Foil in the printed board.

The best characteristics of this learning machine are that collection study and amusement are one, be exactly the brain that adopts the Received Pronunciation of machine to stimulate the learner from the beginning, simultaneously can see picture and text, listening, opening says that the study-leading person learns, consolidates and grasp the orthoepy of each phonetic in light, happy process from start to finish.Learn like this, impression is necessarily very dark and be difficult for forgetting, and under unmanned situation about instructing, it is fine also to learn, very sturdy.It can be widely used in preschool class and primary school, and particularly those educate the suburb, county of poor ridge and the child in rural area.The employing of this learning machine, the popularization to primary school's Chinese phonetic alphabet education and mandarin has important facilitation and realistic meanings.It is simple in structure, and is with low cost, and volume is urinated in carrying.Accepted by society easily.
