Abstract
The utility model belongs to an audio-visual computer for learning a language. The audio-visual computer for learning a language is composed of a reproducer cassette mechanism with two channels (1), an operating mode selecting switch (2), an audio amplifier (3), an earphone (or a loudspeaker) (4), a detector for picture and character information (5), an SCM system (6) and a liquid crystal display (7). The audio-visual computer for learning a language has the function for displaying pictures and characters. The audio-visual computer for learning a language can display Chinese characters, foreign words and various arithmetic relational expressions. The audio-visual computer for learning a language can also emit speech which is synchronous with the display for pictures and characters. The speech can be Chinese, a foreign language or music, etc. The information carrier of the audio-visual computer for learning a language is an ordinary audio tape. The audio-visual computer for learning a language has the advantages of small volume, power expenditure saving, euphonic speech, clear display, etc.
Description
The utility model belongs to the Aduio-visual language learning machine of learning usefulness.
At present, the learning machine of widespread usage has household PC learning machine, language learner, magnetic card learning machine etc.The household PC learning machine has word processing, advantages such as computing function is strong, if but do not dispose voice processing card, then there is not language process function, do not have voice yet and send function, thereby can't carry out the study of voice yet, and, the cost of sound card and computer learning machine is all higher, is difficult to apply in the family.Pronunciation-learning system can only be heard the voice that will learn and the sound that the learner sends is noted again, does not show and have with the corresponding literal of voice, makes troubles to study.The magnetic card learning machine can only read out the mode of the information on the magnetic card with voice, and the information storage of magnetic card is limited, and therefore, for addressing these problems, the utility model provides a kind of novel Aduio-visual language learning machine.
The purpose of this utility model provides a kind of learning machine that the picture and text Presentation Function is arranged, and it can show Chinese character, foreign language, can show various operation relation formulas again, and is furnished with the voice with the picture and text display synchronization, and voice can be Chinese, foreign language or music etc.
Main composition of the present utility model is: a kind of Aduio-visual language learning machine, it is made up of binary channels cassette player movement ［ 1 ］, mode of operation selector switch ［ 2 ］, note amplifier ［ 3 ］, earphone (or loudspeaker) ［ 4 ］, graph text information detecting device ［ 5 ］, Single Chip Microcomputer (SCM) system ［ 6 ］, LCD ［ 7 ］ as shown in Figure 1.
Mode of operation selector switch ［ 2 ］ is when being in mode of learning, to learn tape and insert the band cabin, record picture and text and voice messaging respectively on two track parts of learning tape (common sound-track engraving apparatus tape), these information are after magnetic head becomes electric signal, be sent to note amplifier ［ 3 ］ and graph text information detecting device ［ 5 ］ respectively simultaneously, voice messaging is after note amplifier amplifies, sending into earphone sounds, simultaneously, Word message detecting device ［ 5 ］ is delivered to Single Chip Microcomputer (SCM) system ［ 6 ］ with detected graph text information, graph text information is after Single Chip Microcomputer (SCM) system ［ 6 ］ identification is handled, and the control LCD displays it.
Accompanying drawing of the present utility model has:
Fig. 1, Aduio-visual language learning machine electricity theory diagram
Fig. 2 A, Aduio-visual language learning machine electrical schematic diagram
Fig. 2 B, Aduio-visual language learning machine electrical schematic diagram
Below in conjunction with description of drawings embodiment of the present utility model:
As shown in Figure 1, the Aduio-visual language learning machine that provides of the utility model is made up of binary channels cassette player movement ［ 1 ］, mode of operation selector switch ［ 2 ］, note amplifier ［ 3 ］, earphone (or loudspeaker) ［ 4 ］, graph text information detecting device ［ 5 ］, Single Chip Microcomputer (SCM) system ［ 6 ］, LCD ［ 7 ］.Mode of operation selector switch ［ 2 ］ is when being in mode of learning, learning tape is inserted in the tape deck of binary channels cassette player movement ［ 1 ］, record respectively on two track parts of learning tape voice messaging and graph text information are arranged, during learning machine work, magnetic head will call the roll of the contestants in athletic events voice messaging and graph text information out simultaneously, and become corresponding electric signal, and wherein voice signal is directly sent into 6 pin and 3 pin of note amplifier CXA1034P, this signal is exported by 14 pin and 11 pin after CXA1034P amplifies, through C
8, C
12After being coupled to earphone ［ 4 ］, the voice messaging reduction is exported by earphone.The graph text information that is detected by magnetic head is then linked to each other with 1 pin of the BA328 of graph text information detecting device ［ 5 ］ through the graph text information transmission line A of Fig. 2 B by the graph text information transmission line A of Fig. 2 A, enters BA328, and this signal is exported by 3 pin after BA328 amplifies, then by capacitor C
16, C
17And resistance R
12Be coupled to the reverse input end of LM399, to its shaping, the signal after the shaping is directly inputted to the P of single-chip microcomputer 8031 by the output terminal of LM399 through LM399
35Pin, this facsimile signal is directly controlled LCD ［ 7 ］ after Single Chip Microcomputer (SCM) system ［ 6 ］ identification is handled, graph text information is shown.Like this, learning machine promptly has voice, has picture and text to show synchronously again when work, can give full play to learner's audiovisual function.
When the mode of operation selector switch was selected playback modes, graph text information detecting device ［ 5 ］, Single Chip Microcomputer (SCM) system ［ 6 ］, LCD ［ 7 ］ all quit work, and at this moment, learning machine is a common binary channels cassette player.
The Xin Xi Zai body of this Xi machine is common audio tape. Xi facility You volume Xiao, power consumptive province, Yu Yin Yue ear, Xian show the unique You points of Yi Xi row such as clear.
