Abstract
A reading and writing posture prompter for correcting incorrect reading and writing posture is composed of an earphone frame, two earphone boxes at both sides, mercury trigger switch in one earphone box, and sound and light emitting circuit in another earphone box, which are connected by two wires. The utility model has the advantages that: convenient to wear, and the warning is accurate, has showing the effect to correcting incorrect reading and writing posture.
Description
The utility model relates to a kind of acoustic-optic alarm, is particularly useful for correcting incorrect read-write posture and the acoustic-optic alarm that produces.
Reading, the posture of writing are not rectified, and the distance of eyes and book paper is too near, is easy to cause myopia, and serious meeting forms hunchback, is unfavorable for teen-age healthy.A kind of pre-myopia prevention table card is arranged in the market, is the grille that is clipped in the desk limit, though can hinder incorrect sitting posture, the normal activity scope that has also hindered staff simultaneously; It is myopia prevention desk lamp that prior art also has a kind of, and it is to utilize far infrared to accept the change in location of human body head, when human head location is incorrect, can sends warning or cut off mains lighting supply automatically, and its weak point is to only limit to use night.
The purpose of this utility model is to provide a kind of read-write posture prompting device in order to overcome above-mentioned weak point, and this device ties up to people's head, can not influence the free movable of staff; This prompting device is no matter daytime, night can both carry out sound and light alarm to incorrect posture.
Description of the present utility model is as follows: the read-write posture prompting device is made up of ear frame, Earphone box first, Earphone box second, trigger switch, the sound equipment circuit of giving out light.Ear frame has elasticity, is worn on head.At the two ends of ear frame Earphone box first, Earphone box second is housed respectively, makes hinge pin and connect.The mercury trigger switch is housed in the Earphone box first.The glass tubule of two splayeds or herringbone placement is arranged at mercury trigger switch bottom, and the end of two leads is arranged on the intratubular top of glass, is marked with mercury ball in the tubule, becomes closed state.When inclination Earphone box first, the intratubular mercury ball of glass will be rolled to the other end, and two leads on the top that is positioned at pipe are connected, and connect circuit.When Earphone box first reset terminal positive position, mercury ball is rolled into bottom, disconnecting circuit again.The sound equipment circuit of giving out light is housed in Earphone box second.Circuit is made up of dc source, two-way switch, light emitting diode, IC, loudspeaker, and light emitting diode and IC, loudspeaker are connected in parallel in the circuit, and two contacts of two-way switch link to each other with circuit of LED, horn circuit respectively.
The course of work of read-write posture prompting device is such: two-way switch is connected IC, horn circuit, the ear frame of prompting device is worn on the head, when the head posture was rectified, the mercury trigger switch disconnected; When the head fault, when tilting to a certain degree, wear the mercury in the overhead trigger switch, be subjected to gravity and roll, thereby connect lead, send chimes of doom in the loudspeaker, point out you posture and will rectify.In some occasion, in the time of should not sending chimes of doom as the classroom, two-way switch can be connected circuit of LED, when read-write posture was incorrect, light emitting diode can send light, points out you, must rectify your posture.
Be described further below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.1-ear frame among the figure, 2-Earphone box first, 3-Earphone box second, 4-connection lead.
Fig. 2 is a mercury trigger switch structure chart.4-connection lead among the figure, 5-glass tubule, 6-mercury ball.
Fig. 3 is the sound equipment circuit diagram of giving out light.E-battery supply among the figure, 4-connection lead, K-two-way switch, LED-light emitting diode, IC-integrated circuit, BL-loudspeaker.
Embodiment makes like this: ear frame (1) adopts the general ear frame in market.Earphone box first (2), Earphone box second (3) are contained in the two ends of ear frame (1), have hinge pin to connect.In the box of Earphone box first (2) the mercury trigger switch is housed, the glass tubule (5) that the bottom has two splayeds or herringbone to place.The glass tubule is directly through 4 millimeters of ∮.The termination that two leads (4) are arranged on glass tubule top.Be marked with mercury ball (6) in the glass tubule, become closed.The sound equipment circuit of giving out light is housed in the Earphone box second (3).Mercury trigger switch and the sound equipment circuit of giving out light couples together with two leads (4).In sound equipment was given out light circuit, power supply adopted the 3V battery, and integrated circuit adopts KD9561B.Two-way switch K can insert circuit of LED or audio ic respectively, when read-write posture is incorrect, does the prompting of bright dipping or sound respectively.
Advantage of the present utility model: wear conveniently, report to the police accurately, to not just not correcting True read-write posture has significant effect.
