The usage is convenient.

Description

A kind of hard of hearing formula myopia-preventing and kyphosis-preventing reminiscences

The utility model relates to the warning reminding device that a kind of reminds people keeps the head normal posture.

Existing small-sized reminiscences generally has two kinds, it is a kind of as Chinese patent ZL93202588.9 and Chinese patent ZL92217215.3 are disclosed, the shell of reminiscences is made into the shape that is similar to auricle, hang on the ear and use, enclosure interior is provided with warning devices such as angular displacement touch switch and hummer, wherein the angular displacement touch switch adopts the form that liquid touches, as the mercury angle switch; It is another kind of as Chinese patent ZL91230485.5 discloses, a hook that is used to hang on the ear is set on the shell of reminiscences, this hook can be regulated the angle of whole housing, and the angle displacement touch switch in the housing adopts swing arm to touch slice structure.Other also has some reminiscences in the outer setting support of the housing form as earphone.These reminiscences all are that alarm is with regard to warning reminding after user's head inclination meets or exceeds fixing angle; But these reminiscences all can not be regulated the angle of this inclination, make these reminiscences can not be according to the requirement of different people, the body inclination angle when selecting to remind.The angular displacement touch switch structure of existing reminiscences is also undesirable simultaneously, installs and uses all inconvenient.

The purpose of this utility model is, for the hard of hearing formula myopia-preventing and kyphosis-preventing reminiscences that provides a kind of initial position that can adjust the angular displacement touch switch to adjust the warning angle within the specific limits arbitrarily is provided.

A kind of hard of hearing formula myopia-preventing and kyphosis-preventing reminiscences, comprise housing, ear-hang, battery, contactor, circuit board, integrated package, little axle, handle, angular displacement touch switch, acoustical generator, it is characterized in that described angular displacement touch switch has a critical visual angle to set bar and pendulum mass, the contact rod of restriction pendulum mass hunting range places this critical visual angle to set on the bar.

The utility model can be adjusted the initial position of angular displacement switch, and the user can adjust the shake-up angle according to own different demand, can realize the warning reminding of differing tilt angles, and is easy to use.

Further specify the utility model below by embodiment and accompanying drawing.

Fig. 1 is a sectional structure synoptic diagram of the present utility model.

Fig. 2 is its side-looking sectional structure synoptic diagram.

Fig. 3 is the structural representation that bar is set at its handle and critical visual angle.

Fig. 4 is its index dial structural representation.

Present embodiment has a housing 1 and ear-hang 2.The angular displacement touch switch is equipped with in the bottom in the housing 1, and battery 3, contactor 4, printed circuit board (PCB) 13, imitative animal cry integrated package 14 and acoustical generator 15 are equipped with in top.This angular displacement touch switch has a critical visual angle to set bar 10 and pendulum mass 8.The contact rod 9 of restriction pendulum mass 8 hunting ranges places this critical visual angle to set on the bar 10, can change its position with moving of the latter.Pendulum mass 8 can rotate around axle 5, and it often will be in vertical state owing to gravitate.This axle 5 is fixed on critical visual angle and sets on the bar 10, and the latter also is contained on the little axle 16, and can rotate around this little axle 16, and the angle of rotation can be controlled by being fixed on the handle of setting on the bar 10 at critical visual angle 6.The two ends of this little axle 16 are fixed on the inwall of housing 1.Handle 6 stretches out outside the shell by the side mouth 7 of housing 1, and a plurality of grooves 11 are arranged on the inwall of this side mouth 7, and these grooves 11 are being on the arc in the center of circle with axle 5 all.There is index dial 18 both sides at housing 1 lateral port 7.One projection 17 is arranged on the relevant position of handle 6, and this projection 17 matches with the size and the shape of above-mentioned groove 11, and this projection 17 can buckle into this groove 11.Like this, handle 6 can drive critical visual angle and set bar 10 rotations, the latter's position can select grooves 11 to determine by the sign line on the handle 6 12, therefore pulls handle 6 and can adjust relative position between charged pendulum mass 8 and the contact rod 9, to adjust the shake-up angle of warning.It is more accurate that index dial 18 can make critical visual angle set bar 10 location.

Circuit of the present utility model is known, has just omitted here.
