Embodiment 1

[0044] Such as figure 1 As shown, the anti-myopia method corresponding to the electronic equipment of the present invention may further comprise the steps:

[0045] S1: The speaker emits an ultrasonic signal;

[0046] The electronic device has its own audio system consisting of a microphone, a speaker, and a central processing unit. An application program is downloaded in the central processing unit. The application program controls the speaker 1 to emit a sound wave signal above 18KHz by calling the audio driver application program interface.

[0047] S2: the microphone receives the echo signal;

[0048] When the ultrasonic signal meets the target during transmission, it is reflected to form an echo signal, which is received by the microphone.

[0049] S3: Process the echo signal to detect whether there is a dynamic target in the detection area;

[0050] The central processing unit processes the echo signal, processes the echo signal according to the dynamic detection part...

Embodiment 2

[0056] Such as figure 2 As shown, a kind of anti-myopia electronic equipment includes an audio module and a central processing unit, and the audio module includes a microphone 2 and a loudspeaker 1, and the above-mentioned loudspeaker 1, microphone 2 and the central processing unit are common sound-emitting and sound-receiving electronic devices. The hardware of the device 3 itself, and the connection relationship between the three are also the connection relationship between the hardware of the common sound-emitting and sound-receiving electronic device 3 itself.

[0057] An application program is downloaded in the central processing unit, and the method for preventing myopia of an electronic device in Embodiment 1 is executed by running the application program.

[0058] Specifically, the application program includes a driving part, a dynamic detection part and a distance detection part;

[0059] The driver part calls the application program interface of the audio driver to...

Embodiment 3

[0063] The difference between Embodiment 3 and Embodiment 2 is that the electronic device is specifically a tablet, and the audio module that comes with the tablet includes a microphone and a speaker, and also has a central processing unit. The structure and connection relationship of the three are determined. The application program is downloaded to the tablet, and the central processing unit runs the application program to execute the method for preventing myopia of the electronic device in Embodiment 1.

[0064] Specifically, the application program includes a driving part, a dynamic detection part and a distance detection part;

[0065] The driver part calls the application program interface of the audio driver to complete the control of the bottom audio module of the tablet.

[0066] The driver part completes the control of the underlying audio hardware part by calling the application program interface of the audio driver. Most of the tablet computers on the existing mar...

Abstract

The invention discloses a shortsightedness prevention method of electronic equipment, shortsightedness prevention electronic equipment and a shortsightedness prevention tablet personal computer. The shortsightedness prevention method comprises the steps that a loudspeaker sends out an ultrasonic signal; the microphone receives the echo signal; the echo signal is processed, and it is detected whether a dynamic target exists in a detection area or not; if the dynamic target exists in the detection area, the distance between the dynamic target and the electronic equipment is calculated, and whenthe calculated distance is smaller than a set distance threshold value, the loudspeaker gives an alarm; and the steps are continuously repeated to carry out cyclic detection. The shortsightedness prevention electronic equipment and the shortsightedness prevention tablet personal computer both comprise audio modules and central processing units, application programs are downloaded in the central processing units, and the shortsightedness prevention method is executed by running the application programs. According to the shortsightedness prevention method of the electronic equipment, the shortsightedness prevention electronic equipment and the shortsightedness prevention tablet personal computer, distance detection and reminding are conducted on a user through the audio system of the electronic equipment, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of ultrasonic and audio signal processing, in particular to an anti-myopia method for electronic equipment, an anti-myopia electronic device and an anti-myopia tablet. Background technique [0002] Tablets and similar electronic devices have become the main educational equipment for children, and their increasing frequency of use has made them a major cause of myopia in children. It is becoming more and more important to effectively prevent myopia caused by children using such electronic devices for learning and entertainment. [0003] Now, to solve this problem, the main methods are as follows: [0004] 1. Use the mechanical structure for external force correction. For example, use a desk to correct sitting posture to keep a distance from books to prevent myopia. A common example is the Chinese patent No. 201410803128.1, which is a table for preventing myopia for children. By changing the inclination of t...
