Problems solved by technology

Due to the influence of factors such as the structure of the volume switch and the limitation of the space occupied by the switch electronic parts, it is not possible to set many volume adjustment gears; and even if many volume adjustment gears are set, it is impossible to fully adapt to the irregularly changing environmental influences.
Especially for young users, if you don’t pay attention, you will either not hear the reminder sound or the reminder sound is too loud to affect others
This problem can be solved by setting the earphones, but the earphones have the following disadvantages. The first is that the earphone plug in the ear hole affects the hearing of one ear, and the current smallest earphone diameter is 18mm, especially for primary school students whose ear holes are small for a long time. Use will cause ear cartilage to be compressed and cause pain; second, because the earphone and the reminder are separated, it is inconvenient to carry and can easily be damaged due to the user's carelessness; third, the production cost is high; fourth, it affects the reminder The effect of using

Embodiment 1

[0026] Such as figure 1 Shown, a kind of eye protection reminder that gradually raises the reminder volume includes a circuit board 1 that provides various functions of the reminder; the circuit board is connected to a power supply 2 that supplies its electric energy; A generator 3; an angular displacement switch 4 that triggers the circuit board according to a pre-set angular displacement; a housing 5 containing the above-mentioned components; the housing is provided with a device suitable for attaching the reminder behind the ear The earhook 6, the internal setting of the circuit board 1 is also a time counter triggered by the angular displacement switch; and a plurality of reminder volume gears set from low to high in a ladder shape; the reminder volume gears are judged by an AND gate Select, one of the variables judged by the AND gate is the conduction signal of the angular displacement switch, and the other variable is a certain time period of the time counter. The remin...

Embodiment 2

[0039] It is simpler than the method of depositing the reminder sound in Embodiment 1. Only a selected sound source is stored. When the reminder plays the reminder sound, the sound source is changed in different time periods according to the principle that the sound gradually becomes louder with time. The magnification ratio can also be achieved. Compared with the logic controller in Embodiment 1, this logic controller is provided with more calculation functions of proportional amplification, for example, the CPU in the single-chip microcomputer can realize this function.

[0040] The program of the eye protection reminder that gradually raises the reminder volume is:

[0041] A. Determine whether the angular displacement switch is triggered, if so, continue to proceed, otherwise continue to judge this item;

[0042] B. The time counter starts counting, and its variable is i;

[0043] C. When the time counter satisfies 0≤i<3 seconds, the sounder plays according to the remind...

Abstract

The invention relates to an eye protective reminding device of gradually increasing reminding sound. The said device is equipped with switch triggered time counter of angular dispacement. When the time counter is triggered, the time quantum of the time counter is longer, and the corresponding selective awoking volume step is higher. The invention also relates to a program design suitable for the reminding device. The awoking voice of the reminding device increases at a certain rule from a minor awoking voice. Because the reminding device is hanged by the ear of the user, the user is always the first people hearing the awoking voice no matter what surrounding enviroment it it. If only the user looks up at once, the awoking voice stops. The invention solves the ambient noise problem that hand adjustment of the awoking volume can not fit for irregular change.

Description

Technical field [0001] The invention belongs to an eye protection reminder, in particular to an improvement on the reminder volume control of the reminder. Background technique [0002] Before the present invention, like the eye protection reminder disclosed in Chinese patent ZL01226185.8, 01226184.X, 0119400.6, when the reminder is triggered, in order to make the reminder sound clear, it will not be overwhelmed by the reminder sound. If it is too large to affect other people, the user has to adjust the reminder volume switch to select a suitable volume according to the environmental conditions at that time. Due to the influence of factors such as the structure of the volume switch and the limitation of the space occupied by the switch electronic parts, many volume adjustment gears cannot be set; Especially for young users, if they are not paying attention, either they cannot hear the reminder sound or the reminder sound is too loud to affect others. This problem can be so...
