Description
Technical field
The utility model is related to the technical fields that blind person reads, and are read more particularly, to a kind of blind person based on magnetic fluid
Read smart electronics book.
Background technology
For blind person, read and compare the more of normal person's difficulty, they generally pass through voice or spy to external information
The books for the blind of system obtain, but it is limitation only to obtain information with voice, and words cognitive ability cannot improve, and self-learning ability can not also fill
Distribution is waved.And books for the blind complex manufacturing technology, price are as many as several times of general books, books for the blind sale is again less on the market,
Blind person is more difficult to seek book information, even obtaining books for the blind, it is also more inconvenient to carry.For not receiving the people of braille education
For, braille is failed to see, books for the blind can not be understood.
At present, there is currently portable braille reader be commonly two kinds of designs：One kind is to be carved with control with braille
The content transformation shown in read area can be voice output when user touches button by the control zone of button；One kind is
By operating function button, needed by selection, data message in flash disk can be transmitted to FPGA master control moulds by usb communication module
Block performs corresponding software, completes corresponding function, and blind person can be shown screen by braille point and quickly and easily be read.However, the former nothing
Method meets teaching request, and blind person only is difficult to be associated with corresponding word with the voice messaging of acquisition, obtains the character learning ability of reading
Less than raising and at some such as the special circumstances of complex mathematical formula, can not be only better understood from by voice；Though the latter solves
The defects of preceding kind of equipment of having determined occurs, but braille point show screen it is high in technological content, research and development difficulty it is big, can not be undertaken for average family
Expensive cost of equipment.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of corresponding as braille using magnetic current body unit
Being quick on the draw of device, it is small be easy to carry about with one, the blind person that low energy consumption reads smart electronics book.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of blind person based on magnetic fluid is provided and reads smart electronics book, including the bottom case, coil collection plate, magnetic being linked in sequence

Further, the coil, the film micropore are corresponded with the magnetic fluid box, and the film micropore
At the center of the magnetic fluid box.When coil nearby generates magnetic field, magnetic fluid can raise up under the influence of a magnetic field,
Each magnetic fluid capsule center is there are one film micropore, when magnetic fluid is when magnetic fields raise up, magnetic fluid top tip part
Branch protrudes, so as to form concave-convex state on e-book screen.
Further, the magnetic fluid includes the magnetic retention particle of several a diameter of nanometer scales, the magnetic retention
Particle coil no current by when smooth pile up in the magnetic fluid box.Magnetic retention particle is quick on the draw to magnetic field,
When coil have electric current by when, magnetic retention particle is by the convex state of magnetic fields；When coil no current by when, magnetism is solid
Body particle is smooth to be piled up in magnetic fluid box；And the e-book so set have be quick on the draw, be small, the spy that low energy consumption
Point.
Further, the diameter of the magnetic retention particle is less than the diameter of the film micropore, and the magnetic-particle is consolidated
The height that body is piled up is less than the height of the magnetic fluid box.When coil alives, magnetic fluid under the influence of a magnetic field can be to
Upper protrusion, magnetic fluid top tip part branch protrude from film.
Further, the film is shaping and the elastic membrane structure of recovery deformation.Film has certain elasticity, when
Both shaping or deformation can be recovered when magnetic fluid state changes, and magnetic fluid had been strapped in magnetic fluid collection plate, anti-fluid stopping
Go out.
Further, the bottom case is equipped with lithium battery and for common language to be converted to voice messaging and braille letter
The book system of breath, the book system are electrically connected to the output terminal of the lithium battery.The setting of book system makes blind
People receives voice reading and sense of touch and reads simultaneously, and it is to be associated with corresponding word to solve voice messaging of the blind person only with acquisition
The problem of making words cognitive ability that cannot improve.
Further, the book system includes microcontroller, control element, loud speaker and function button：
Common language is converted to voice messaging and the corresponding program of braille information by microcontroller for typing；
Control element receives the signal that microcontroller is sent, and the information for microcontroller to be transferred, which is converted to, is powered to coil
The control of state；
Loud speaker, receives the signal that microcontroller is sent, and the information for microcontroller to be transferred is converted to voice messaging output；
Function button sends signal, for whether controlling power switch, sound size, control voice information to microcontroller
Whether output, control braille information export and for front and rear page turning.
Further, the function button is equipped with braille point corresponding with the function of the function button.Function button
On be carved with braille point convenient for blind person power switch, sound size, voice is controlled whether to export exactly, the functions such as front and rear page turning.
Further, the coil, the magnetic fluid box, the quantity of the film micropore are laterally 40 ~ 60, longitudinal direction
50 ~ 70；The magnetic fluid forms braille point in coil effect lower convexity, and laterally 1 ~ 3 braille point, longitudinal direction 2 ~ 5 are blind
Text point is formed as a braille.The e-book so set is small, readily carried about, is user-friendly.
Compared with prior art, the beneficial effects of the utility model are：
（1）Using magnetic fluid as braille responding device, have and be quick on the draw, be small, the characteristics of low energy consumption, and in contrast to
Other electronic book for blind person systems on the market, user can carry, more convenient, can help to improve the life of physical disabilities
Bioplasm amount；
（2）Blind person can select reading model to read what is combined with sense of touch for voice reading, sense of touch reading or voice reading
Mode facilitates use of the e-book in different occasions, solves and does not receive the people of braille education and fail to see braille and can not understand braille
The problem of in the predicament of book and braille teaching process to complicated word or mathematical formulae teaching difficulty；
（3）Low manufacture cost has evaded existing electronic book for blind person and has shown the high in technological content cost of manufacture height of screen using braille point
The defects of and improve read words cognitive ability, self-learning ability for blind person and provide convenience.
