Background technology
Braille is braille just, it is the special-purpose literal that uses for the dysopia personage, the general braille in the whole world is Frenchman Louis Blair's utility model now, it is a structure with the point of six projectioies, by the conversion of six some positions and the different formation brailles of distance, the braille of China is based on the Chinese phonetic alphabet, the braille that is transformed into by 56 notes.According to incompletely statistics, China has the blind person more than 90% to be ignorant of braille approximately, and they can not share the world culture resource of Feng Yun as the normal person, can't learn other professional techniques just, become a great society difficult problem.
The blind person adopts the reading tool of papery mostly when the study braille now, adopts blind pen to prick the salient point that comes out on the paper of speciality these 56 notes and indicates, during reading, go to touch with hand again.And this braille of coming out of pricking on paper has exerted oneself can polish salient point, cause the braille lost of life big, therefore is not suitable for the repeatedly touch of learner in learning process.And the mode of learning of paper can't obtain the pronunciation of each word, also needs to consult others, is not suitable for learning by oneself.
At present, the blind person learns braille and mainly arrives special braille school, this has higher requirement to qualified teachers' strength undoubtedly, also can increase the weight of simultaneously the financial burden of braille family, concerning the blind person who has learned braille, in the process of working and learning, also there are professional knowledges such as many vocabulary, symbol to need frequent going to browse thick books printed in braille, it is very painstaking that study is got up.
The utility model content
The utility model has overcome above-mentioned shortcoming, and a kind of electronics braille dictionary of learning, searching braille voluntarily is provided.
The technical scheme in the invention for solving the technical problem is: a kind of electronics braille dictionary, comprise housing and the control circuit that is arranged in the housing, the panel of described housing is provided with braille typing button, function setting button and vocal hole, described control circuit comprises successively the CPU (central processing unit) that connects, voice warning circuit and corresponding to the loudspeaker of described vocal hole position, described braille typing button links to each other with described CPU (central processing unit) respectively with the function setting button, and described CPU (central processing unit) also is connected with storer.
Described housing is provided with USB interface, and described USB interface is connected with described central processing unit.
Described loudspeaker adopts the stereophony loudspeaker.
Described braille typing button is made of the resilient contact that is provided with the braille phonetic alphabet.
Described braille typing button is made of braille phonetic alphabet and the typing button that is arranged on braille phonetic alphabet next door.
Described function key can adopt the tumbling-type button or/and the push type button.
The side of described housing is provided with the earphone jack that links to each other with described voice warning circuit.
The next door of described each braille typing button also is provided with the Chinese phonetic alphabet or Chinese sign.
The utility model is when pressing the function setting key, extract the function corresponding data of storage, press braille typing button then, risk the Chinese character pronunciation that to look into, voice warning circuit will sounding, the content that prompting will be inquired about realize a kind ofly need not artificial guidance, but blind man is learnt braille voluntarily, the mode of available language prompting is verified the knowledge of reading the braille aspect again, use for a long time as reference book, become blind person's good teacher and helpful friend, follow the blind person to use throughout one's life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the theory diagram of control circuit in the utility model.
Embodiment
As shown in fig. 1, the utility model comprises housing 1 and is arranged on the control circuit of housing 1 inside, the panel of described housing 1 is provided with braille typing button 2, function setting button 3 and vocal hole 4, described braille typing button 2 is made of the resilient contact that is provided with the braille phonetic alphabet, perhaps constitute by braille phonetic alphabet and the typing button that is arranged on braille phonetic alphabet next door, bump structure by touching perception braille phonetic alphabet is also pressed button, realizes the braille typing.The next door of described braille typing button also is provided with the Chinese phonetic alphabet or Chinese sign., for example above each braille typing button 2, can also indicate the corresponding Chinese phonetic alphabet, to be convenient to the normal person the bright guidance that provides is provided, described function setting button 3 is provided with the braille sign (figure does not indicate) that is used for distinguishing difference in functionality.
Described control circuit as shown in Figure 2, comprise successively the CPU (central processing unit) that connects, voice warning circuit and corresponding to the loudspeaker of described vocal hole position, described braille typing button links to each other with described CPU (central processing unit) respectively with the function setting button, and described CPU (central processing unit) also is connected with storer.Described loudspeaker adopts the stereophony loudspeaker, is separately positioned on the both sides of case panel, produces surround sound.Described voice warning circuit comprises phonetic synthesis module and power amplifier, and described phonetic synthesis module is the synthetic sound signal that will enter under the control of central processing module, through after the amplification of power amplifier, goes out by loudspeaker plays again.
The size of 56 braille phonetic alphabet of braille typing button conforms to the braille of reality on the panel, the blind person is in learning process, touch repeatedly that can be repeatedly, after findding out a numerical digit, can a little down press button, and then send key command to described CPU (central processing unit), and then trigger voice warning circuit and pronounce accurately, after also can pressing button earlier and pronouncing, go touch to count and putting the position, by voice suggestion, avoided blind person's irritated and in a depressed state in learning process, can be familiar with and learn 56 letters of braille soon.Behind 56 phonetic alphabet of association, just can organize word, group sentence, the same with the mosaic mode of the Chinese phonetic alphabet, initial consonant and simple or compound vowel of a Chinese syllable add tone just can risk Chinese character, and then the professor blind person writes braille, uses braille.
