Abstract
The utility model relates to a reminding instrument for prevention of nearsightedness and hunchback, which comprises an elastic positioning clamp and earphone frames which are respectively fixed onto both ends of the elastic positioning clamp; the internal parts of the earphone frames are provided with a musical chip, a buzzing chip, and a button battery which are mutually connected, and on-off of a power supply can be controlled by a position control switch. The utility model overcomes defects of a mechanical device for prevention of nearsightedness and hunchback of complicated structure, large size, inconvenient carrying and usage, poor comfort, and high cost, inaccurate distance measurement, and unfavorable effects of an electronic type device for prevention of nearsightedness and hunchback. The utility model has the advantages of simple structure, convenient carrying and usage, low cost, saved power consumption, and accurate control.
Description
The utility model relates to the bow-backed prompting instrument of a kind of myopia prevention.
The structure of the bow-backed device of known myopia prevention is various, and a kind of is pure physical construction, and it fixes human body sitting posture by the mode of fixed mount, has complex structure, and volume is big, portably uses inconvenience, the defective of comfortableness difference.And another kind is pure electronic type structure, be placed on during use on the desk, by the infrared ray of emission measure and human body between distance, when being less than a certain setpoint distance between human body and the desk, will sending automatically and remind music or buzzer.Also there is the line construction complexity in this alarm set, the cost height, and the range finding accuracy is low, the defective that result of use is relatively poor.
The purpose of this utility model is to overcome the problems referred to above that prior art exists, thereby provides a kind of simple in structure, easy to use, the bow-backed prompting instrument of myopia prevention that precise control is high.
The utility model comprises the elasticity locating clip and is separately fixed at the ear frame at elasticity locating clip two ends, is provided with interconnective musical film, piezo and button cell in the ear frame, and the break-make of power supply is by the control of position control switch.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises elasticity locating clip 1 and is separately fixed at the ear frame 2 at elasticity locating clip 1 two ends, forms the common headphones shape, during use, can be fixed on human body head as common headphones, elasticity locating clip 1 can be made by metal material or plastic material.Be provided with interconnective musical film 3, piezo 4 and button cell 5 in the ear frame 2, the break-make of power supply is by 6 controls of position control switch, and control switch in position adopts mercury cut-off, can be arranged on simultaneously in the ear frame 2, also can be fixed on the locating clip 1.When human body used prompting instrument with normal sitting position, control switch in position was in off-state, and power supply is obstructed, when human body sitting posture changes, promptly during the changing apart from angle of human body head and desk, the mercury in the mercury cut-off moves, switch conduction, piezo 4 is sent the prompting sound.
The utility model is by above-mentioned concrete setting, have simple in structure, portably use conveniently, cost is low, Power consumption is economized, the advantage of precise control.
