The machine has the functions of showing multiplication and English letters, reciting multiplication, sending out the pronunciation of 26 English letters, etc. The learning machine is small in size, strong in flexibility, and is an ideal learning tool for children.

Description

Speech sound type machine for learning

The utility model relates to a kind of microprocessor-controlIed multiplication and alphabetical learning machine.

The study of voice and mathematics is the most basic, the most important education of the mankind, and human research to voice and mathematical education never stopped.Up to the present, about the many purposes that reach teaching with picture, cassette tape mode of the education of voice, mathematics, though in recent years, the pronunciation-learning system that some electronic type occurred, but its operation still can not be broken away from supplementary meanss such as in the past picture, cassette tape, and volume is big, and voice pronounce repeatedly, carry and use extremely inconvenience, especially the basic material to children's multiplication and relevant English alphabet can not propose a cover mobility strong, effective language learning system.

The purpose of this utility model provides a kind of a kind of letter and multiplication learning machine with voice play function that have.It is little that this learning machine has a volume, mobility strong, and portable characteristics are particularly suitable for the children education worker and use.

The utility model is achieved in that learning machine is made up of shell and the internal circuit that is contained in the shell.The operating surface that shell is provided with display screen and has plurality of keys.Internal circuit comprises: the microprocessor of two 4 bits, each microprocessor include central processing unit CPU and the above read only memory ROM/random access memory ram of 10K, can store the voice in 22 seconds, and alienable 64 sections, and both join; A ROM (read-only memory), this storer are attempted by between above-mentioned two microprocessor, can store the voice in 15 seconds, and may be partitioned into 64 storage compartments, and its voice signal is subjected to the 2nd microprocessor control output; A display screen that joins with the first microprocessor output terminal; Button that joins with the first microprocessor output terminal with several key buttons; One with above-mentioned two pronunciation circuits that the microprocessor output terminal joins.

The utlity model has following effect:

1, can show multiplication and individual character (A, B ... Z).

2, can be forward, reverse, continuous, single step recites multiplication.

3, multiplication calculates.

4, English alphabet (A, B ... Z) pronunciation and font understanding.

5, syllogic voice output (loud, little sound, noiseless).

Fig. 1 is the utility model schematic appearance.

Fig. 2 is a circuit diagram of the present utility model.

As shown in Figure 1 and Figure 2, the utility model is by shell 2 and include circuit 1 and form, wherein:

Include the

microprocessor

11,12 that circuit 1 comprises two 4 bits, have a central processing unit CPU in each processor and include the above ROM/RAM of 10K, can store the voice in 22 seconds, and may be partitioned into 64 sections.After above-mentioned two microprocessor joined, with read only memory ROM 12 relevant connecing, ROM12 can store the voice in 15 seconds, and may be partitioned into 64 sections.Display screen 14 joins with the output terminal of microprocessor 11, and pronunciation circuit 15 links to each other with the output terminal of microprocessor 11,12.Button 16 joins with the input end of microprocessor 11.

The outside surface of shell 2 is provided with a display screen 14 and has the operating surface of several buttons.

In Fig. 2,

microprocessor

11,12 is respectively ic chip 1, the IC2 of Mssuool for model, and ROM (read-only memory) 13 is the ic chip 3 of Mss1506 for model; Button 16 is connected with port P4, P3, M1, M2, M3, M4, B3, the B4 of IC1 respectively; Display screen 14 respectively with the COM1,2,3 of IC1, the SEGOUT port connects; The REF of IC1, S3, P2, INT port are connected with VRKF, P1, M1, the B3 port of IC2 respectively; Be connected with T0 to the T5 port of IC3 respectively after port A1, the A2 of IC1, IC2, A3, A4, the corresponding connection of B1, B2; Port B4, the P2 of IC2, P3 are connected with BUSY, PWR, the E2 port of IC3 respectively.Pronunciation circuit 15 is made up of power amplifier and the loudspeaker Y that transistor BG2, resistance constitute, and the port COUT of IC1, IC2 is connected with the base stage of BG2 respectively.

During use, push the button 16 on the shell 2, the signal of input calculates the result in microprocessor 11, outputs to display screen 14 and acoustics circuit 15, makes it to produce the teaching efficiency of letter and multiplication.

In the utility model, the CPU of first microprocessor 11 is a keynote control center, is responsible for the instruction of scanning by button 16 inputs, gives computing, shows or do I/O control, and on the CPU of 2 microprocessor 12 of move instruction to the.ROM (read-only memory) 13 is connected with 6 address ends of

microprocessor

11,12, and accepts the instruction of microprocessor 12.Its circuit characteristic is according to the program of the ROM in the microprocessor and utilizes the storage of RAM as machine row operation, data.The action of CPU in the microprocessor 11 simultaneously can be carried out the action of computing according to button 16, so the utility model can reach aforesaid several functions according to the program and the pressing keys 16 of microprocessor internal memory, that is:

1, can show multiplication and individual character (A, B ... Z), under open state, (REPEAT) among 16 press ﹠ hold earlier again by (multiplication) or pin (REPEAT) earlier and promptly enter the displaying situation by (letter understanding) again, during displaying, multiplication and English alphabet can continue circulation, but voice are not exported, and do not have 8 minutes functions of shutdown automatically, and its display packing is following listed:

LCD DISPLAY voice output

2 * 1=2 does not have

2 * 2=4 does not have

Do not have

9 * 9=81 does not have

A does not have

B does not have

. do not have

Z does not have

2 * 1=2 does not have

Do not have

Finish by (multiplication) or (letter understanding) or (OFF) key, other keys are not accepted.

2, can be forward, reverse, continuous, single step, recite multiplication.

Pressing keys 16 they (multiplication) keys, make enter the multiplication function after, as long as by (▲) key or (

) key, can produce forward, the back of the body of the multiplication of reverse, continuous or single step and pronunciation educates effect

3, the computing function of multiplication

Pressing keys 16, input " multiplicand " reaches " multiplier ", just result of calculation can be presented on the display screen.

4, English alphabet (A, B ... Z) pronunciation and understanding.

By (letter understanding) key, enter the exhalation state of English alphabet, as shown in Figure 1, English alphabet is located on the button with 3 or 2 words, is the 1st word when by the 1st time, and continuing by the 2nd time is the 2nd word, by then being the 3rd word,, circulate according to this more again by then returning to the 1st word.When conversion, the demonstration letter of every key is four sections original lexicographic orders all.As when (7) this button, its 1st display screen 14 will go out ［ S ］ word, and pronunciation circuit 15 is read the right pronunciation of letter simultaneously, and by be ［ T ］ once, pressing again is ［ U ］ then once, adds by once getting back to ［ S ］ again.When and for example key position was ［ T ］, this moment, during again by this key, display screen showed ［ S ］, rather than ［ U ］ when pressing other keys as (X) again.

5, syllogic voice output (loud, little sound, noiseless) and shutdown automatically.

(VOL) key in the pressing keys (16) can change the size of single output, and this key adopts presses the formula work that once changes a volume output, is followed successively by (loud, little sound, and noiseless) and operation capable of circulation.If do not push any button in 8 minutes, learning machine will shut down automatically.
