For introducing card-type electronic didactical doll of the present utility model in detail, be elaborated below in conjunction with accompanying drawing:

By structural representation shown in Figure 1, housing of the present utility model is made up of card plug receptacle 11, storer card insertion base 12, supply hub 13, display 14, keyboard 15, vocal hole 16, card panel 17.

By electronic circuit theory diagram shown in Figure 2, mainly form by power circuit 1, microprocessor 2, IC-card seat and storer (IC-card) 3, keyboard management circuit 4, keyboard 5, voice operation demonstrator 6, audio frequency power amplifier 7, LCD 8, card bed 9 and card 10.

1. power circuit: power supply can be powered by stabilized voltage supply, also can be battery-powered, and when powering with stabilized voltage supply, the battery automatic cutout.Power circuit provides 5v power supply for complete machine.

2. microprocessor: microprocessor is used for the management and the control of phonetic synthesis, liquid crystal display and keyboard, and microprocessor can adopt known chip microcontroller.

3.IC deck and memory: memory is used to deposit program, voice and music data.Memory can link to each other with microprocessor, is fixed on memory and makes plug-in card form (IC-card).Microprocessor links to each other with the IC-card seat, and IC-card links to each other with microprocessor by the IC-card seat again.Can make different IC-cards and corresponding card according to different contents, changing IC-card is renewable contents.

4. keyboard management circuit: it finishes the management to keyboard as an interface of keyboard and microprocessor.

5. keyboard: all orders are imported by keyboard.Keyboard is divided into three groups.One group is that coding key is in order to identification card; Second group of button is figure button or digital keys, presses the key symbols or the corresponding numerical key that indicate on the card figure and can send corresponding voice; The 3rd group of button is function button, includes clock, repetition, adjusting, working method etc., in order to the repetition, working method, adjusting clock etc. of control voice.

6. voice operation demonstrator: form by chipspeech and random access memory ram.Corresponding speech data is extracted from storer 2 by microprocessor 3 controls, delivers among the RAM, synthesizes voice signal by chipspeech again.

7. audio frequency power amplifier: be used for the synthetic voice signal of voice operation demonstrator is amplified.

8. LCD: in order to read clock, score etc., LCD can adopt character type, also can adopt dot matrix type, and former structure is simple, and control is convenient, but the latter then display graphics and literal, displaying contents is abundant.

9. card bed: be the card slot that inserts card, built-in coding key.After card inserted, coding key is closed or disconnection according to the coding on the card, and microprocessor reads this coding can be identified as the insertion of which card.

10. card: every card is made of two parts, and a part is a notch, is positioned at card one side.By binary coding, punching corresponds to number " 0 ", and not punching corresponds to number " 1 ".Another part of card is pattern or literal, and it is marked with and indicates symbol or numeral.

Principle of work of the present utility model is such: behind the logical upward power supply, display can show the time.Can carry out adjustment and the conversion of operation state of time by function key.When being converted to when reading card mode, inserts a card in card bed, which microprocessor determined to have inserted according to the coding of card and opened card, thereby goes to the program segment that phase should card.Press on the card on the pattern or the symbol that is indicated on the literal, the action of figure keyswitch, microprocessor will be stored in the memory corresponding speech data in view of the above and extract, deliver among the RAM of voice operation demonstrator, chipspeech synthesizes voice signal output with the data among this RAM, amplify through audio frequency power amplifier, promote loudspeaker and sound.

According to above-mentioned principle of work, the identification of pattern or literal can be taked dual mode on the card, a kind of is to lay the figure key-press matrix under the panel of card bed, pattern on the card or literal are marked with the sign symbol, corresponding figure button below each symbol is pressed and is indicated symbol and can press figure button under it.First kind of embodiment detailed circuit of Gou Chenging as shown in Figure 3 in this manner.In this embodiment, microprocessor has adopted the MES-51 series monolithic, as 8031 (U1); Memory adopts 27256 (U4); Keyboard management circuit has adopted 8279 chips (U3) to realize, maximumly can reach 8 * 8=64 by bond number, and 8279 what adopt is the interrupt scanning mode; Chipspeech has adopted the TC8830AF of Toshiba (U6), and static memory SRAM adopts TC55257 (U7), 256K position; Audio frequency power amplifier adopts LM386 (U9) to realize; The model of LCD is LCM-10 (U8), and it is 10 liquid crystal, and operating voltage is 1.5V only, and power consumption is extremely low, includes clock circuit, and being connected with microprocessor only needs three I/O mouth lines.

The another kind of mode of pattern or literal identification is on the card, marks numeral on pattern on the card or literal, determines to send corresponding voice by pressing on the keyboard respective counts keyboard.Under this mode, the figure button is not placed under the deck panel, can reduce figure key-press matrix number, simplifies the operation and circuit design, can reduce the size of card simultaneously yet.Second kind of embodiment circuit diagram of Gou Chenging as shown in Figure 4 in this way.Adopted the driving of parallel interface 8255 as keyboard management and LCD among this embodiment, wherein 8 in 8255 PA mouth is used to drive liquid crystal; LCD adopts GM-D40D, is 4 LCD; Keyboard adopts the rank scanning mode to discern, 8 horizontal scanning lines of 8255 PB mouth as keyboard, and 3 column scan lines as keyboard in the PC mouth are formed 8 * 3=24 key, and wherein numerical key 0～9 is totally 10, and 8 all the other 6 of key letters are the mode options button.

Adopt the timer of microprocessor self, no doubt can determine clock, but if will accurately demonstrate the time, can adopt calendar clock chip 5832, the third embodiment of the present utility model as shown in Figure 5, wherein adopt 8255 as parallel interface, 8255 PA mouth and part PC mouth are in order to drive 5832, and PB mouth and PC notch portion are as the keyboard scan line; LCD adopts TMM3 1/2-009, utilize string and conversion shift register 74LS164 as string and conversion, drive liquid crystal with one or seven sections liquid crystal display drive chips of C306 BCD, so only two I/O mouth lines of need can be realized being connected of microprocessor and four LCD.
