Abstract
The utility model relates to a language alarm for preventing myopiab which is characterized in that the language alarm is composed of two sensing elements, a language sheet, a loud speaker, a circuit board, a micro battery and a casing, wherein, one of the sensing elements is fixed with the language sheet, the loud speaker, the circuit board, the micro battery and the casing into integration, and the other sensing element is fixed on the chest neck part and the collar point of a user. The utility model has the advantages of simple structure, low cost, convenient operation, good prevention effect, etc., and is one of the effective tools for protecting the eyes of middle school students and pupils.
Description
This utility model relates to a kind of language reminiscences that prevents hypometropia.
In recent years, because learning tasks are heavy, make increasing teen-age visual deterioration and become the myope.Also do not have at present the device of pre-myopia prevention to occur, the device that designs a kind of effective prevention hypometropia as early as possible is one of problem facing of numerous scientific and technical personnel.
The purpose of this utility model is that design is a kind of simple in structure, and cost is low, and is easy to manufacture, easy to use, the language reminiscences device of respond well prevention hypometropia.
The technical solution of the utility model is: this myopia prevention language reminiscences is made up of parts such as two sensing elements, language sheet, speaker, wiring board, minicell, shells.Sensing element and language sheet, speaker, wiring board, minicell, shell are fixed as one, and another sensing element then is fixed on the breast cervical region and the collar place of user.Two sensing elements are used for controlling its Writing distance by sensing, and sensing element can adopt mistor and gas sensing resistance.The language sheet is to make speaker send the device of speech, as makes speaker send the language of " noting coming back " or " new line ", " new line ", generally repeats twice and gets final product.Speaker is an acoustical generator, and it is according to the instruction pronunciation of language sheet.The effect of wiring board is fixedly sensing element and connection line.Minicell is to provide power supply for sensing element, language sheet, speaker.Shell is for fixedly sensing element, language sheet, speaker, wiring board, minicell are provided with, it can be made into column type or prismatic, also can be made into cap for brush type, be combined into the myopia prevention language with various pens, ball pen, propelling pencil and remind pen, then more elegant in appearance, practical.For using electricity wisely, be preferably in the minicell place and establish a switch, make power connection during use, then close when idle.
During use, one sensing element is fixed on chest, cervical region or head, again fixed other parts and lettering pen are fixed together, when the distance of Writer's eyes and nib closely arrives to a certain degree, the sensing element that is placed in sensing element on the lettering pen and breast cervical region is because the sensing effect, make the sensing element on the lettering pen open the language sheet, the language sheet makes speaker send " noting coming back " or " new line " again, " new line " and other Languages, remind the writer to note Writing distance, thereby prevention hypometropia, when Writer's Writing distance reached requirement, the sensing effect of two sensing elements disappeared, and speaker is also mute.
Advantages such as this myopia prevention language reminiscences has simple in structure, with low cost, easy to use, and preventive effect is good are the effective tools that numerous primary and secondary students protect eyes.
Fig. 1 is a structural representation of the present utility model, also can be used as example structure sketch map of the present utility model.
Fig. 2 is an operation principle sketch map of the present utility model.
Narrated again below in conjunction with accompanying drawing.
In the accompanying drawing: 1 housing, 2 minicells, 3 switches, 4 language sheets, 5 wiring boards, 6 microphones, 7 sensing elements one, 8 sensing elements two.
This embodiment with myopia prevention language reminiscences device on an end of a pen shell, minicell (2) is a button cell, switch (3) is a push switch, and sensing element (7), (8) are selected mistor for use, and sensing element (7) is fixed on the wiring board (5).During use, sensing element (8) is fixed on chest and the collar, holding the pen that this myopia prevention language reminiscences is housed writes, when Writer's Writing distance closely arrives to a certain degree, then two sensing elements (7), (8) will produce the sensing effect and open language sheet (4), language sheet (4) makes speaker (6) pronunciation again, reminds user to note Writing distance, thereby can effectively prevent hypometropia.When if Writing distance reaches requirement, then the sensing effect disappears, and speaker is mute.
