Abstract

The utility model relates to an ear hanging corrector for sitting postures, which belongs to the technical field of health care products. The utility model is composed of a sound emitting box 1, a control circuit, etc., wherein an auricle curve-shaped hook 2 is connected to the sound emitting box 1, so the sound emitting box 1 can be directly hung on an ear. When the upper body or the head of a human body inclines and the inclination exceeds a certain degree, an angle sensor SH arranged in the sound emitting box 1 is switched on, then the sound emitting box emits warning speech sounds to help a user to correct the unhealthy sitting postures in time and thus the function of preventing myopia is performed. The utility model has the advantages of small size, convenient wearing, little electric consumption and accurate and reliable detection to the sitting postures.

Description

Supra-aural correcting sitting posture device

The utility model is a kind of supra-aural correcting sitting posture device that relates to health treatment.

The correcting sitting posture device is a kind of health treatment that is intended to protect blue or green few noon eyesight and health normal development; when the adolescent student reading, when the sitting posture that writes is lack of standardization; it promptly reminds the timely correcting sitting postures of user with voice or other form; keep good read-write posture, thereby play purposes such as preventing eyesight myopia.Prior art is to be installed in the sitting posture detecting element on the desk lamp or in other desktop assembly; as the myopia prevention lamp dimmer of introducing in the 91st page of article of " Beijing electronics newspaper " 93 years bound volumes " repacking myopia prevention lamp dimmer "; the patent No. is 90200254; 6 utility model invention " ultrasound wave reading writing vision protector " etc.; it is bigger that they all have a volume; inconvenience is carried etc. not enough; separate with human body because of its sitting posture detecting element simultaneously; so position relation that the user must be certain with its maintenance; otherwise occur false alarm or out of control easily, it is also not quite convenient to use.

The purpose of the present utility model, it is small and exquisite to provide a kind of volume, is easy to carry, and can directly be affiliated to the correcting sitting posture device on auricle, and the user need only be hooked on it on ear, can send voice warning to its incorrect sitting-pose, helps it in time to rectify sitting posture.

By observing as can be known, people's ears are along with people's the upper body and the swing of head are swung, therefore the angle sensor element is placed people's ear, can detect the particularly degree of tilt of head of human body upper body more direct, exactly, when the angle of inclination surpasses a certain degree, allow the sensing element conducting, make the sound circuit signal that gives a warning, just can reach the purpose that sitting posture is reminded, corrected.If pronunciation component is also placed ear, then can reduce requirement greatly to the pronunciation component volume, only need very faint volume, just can allow the user clearly audible to warning, this had both helped reducing the volume of this device, can reduce circuit and power consumption again, used power supply adopts the small button cell of volume to get final product.

Fig. 1, Fig. 2 are the front elevation and the left views of band auricle hook voice box profile.

Fig. 3 is a control circuit part of the present utility model, and IC is the dedicated voice integrated circuit, and SH is the angle sensor element, when its conducting, and the IC work that just is triggered, voice signal promotes pronunciation component BE pronunciation after triode VI amplifies.

Embodiment of the present utility model.

In the present embodiment, IC is a slice " please note myopia, fast seat just " speech IC, its operating voltage is 3V, and quiescent current has only 5uA, is a kind of little power consumption element, SH is a miniature mercury cut-off, physical dimension is Ф 4mm * 8mm, and when its axis during at horizontal level, its inside is off-state, when axis during along the downward-sloping certain angle of pin one end, its inside, is installed, is fixed in the voice box 1 this element other element in circuit with regard to conducting.Used pronunciation component BE is a sound membrane type insert earphone, and power supply EC is two pieces of AG3 button cells, and SA is a superminiature power switch, and it is installed in the back side of voice box with battery.Sitting posture detects, the voice warning effect in order to make the utility model can both play more accurately to any user, and voice box 1 adopts with auricle hook 2 and flexibly connects, and makes it and can relatively rotate, so that can adjust the conduction angle of angle sensing element in the voice box.

Claims

1. supra-aural correcting sitting posture device, the control circuit that dedicated voice integrated circuit (IC), angular transducer SH, pronunciation component BE etc. form is installed in its voice box 1, sensor SH is connected in the triggering loop of speech IC IC, in case its conducting, circuit promptly sends caution sound, the invention is characterized in that be connected with the hook 2 of people's ear auricle curve sample on the voice box, this hook hangs over the earhole position that can make voice box abut in the people preferably on the ear.

2. according to the described supra-aural correcting sitting posture of claim 1 device, it is characterized in that an end of said auricle sample hook is a garden dish, voice box 1 is buckled in this garden dish, and can be in the dish of garden left-right rotation.

3. according to the described supra-aural correcting sitting posture of claim 1 device, it is characterized in that the back side of voice box is equipped with button cell EC and a micro power switch S A.
