Automatic dustproof device and method

Abstract

The invention discloses an automatic dustproof device used for shielding a voice outlet of electronic equipment. The automatic dustproof device comprises a shell. The voice outlet is formed in the shell. The shell is provided with a window corresponding to the voice outlet. The automatic dustproof device further comprises a coil and a shielding piece used for shielding the window. The shielding piece at least comprises a working face and a side face. The working face is provided with a plurality of magnets. The side face is provided with a telescopic piece. According to the automatic dustproof device and method, the shielding piece is automatically opened and closed, it is effectively ensured that the voice outlet is shielded before a voice diaphragm works and is rapidly opened when the voice diaphragm works, normal voice generation of the voice outlet is not affected, the problem that the voice outlet is exposed to the air in daily use is solved, dust particles are effectively prevented from being adsorbed to the surface of the voice diaphragm, the service life of the voice diaphragm is prolonged, and the using cost of the electronic equipment is reduced.

Description

technical field [0001] The invention relates to the field of device protection for electronic products, in particular to an automatic dust-proof device and method for preventing audio devices from being polluted. Background technique [0002] With the rapid popularization of electronic products in people's daily life, almost everyone needs to have electronic devices such as mobile phones, and the audio devices in electronic devices are essential devices for people's daily calls and voice chats. For example, prolonging the service life of audio devices and preventing accidental damage to audio devices has become the core issue for improving the reliability of audio devices. [0003] Traditional audio devices (such as earpieces and speakers) are easily affected by external foreign objects, leading to failure. The main reason is that audio devices produce sound through the vibration of the sound film, and the sound film is made of brittle materials. A layer of dust-proof net i...

Problems solved by technology

[0003] Traditional audio devices (such as earpieces and speakers) are easily affected by external foreign objects, leading to failure. The main reason is that audio devices produce sound through the vibration of the sound film, and the sound film is made of brittle materials. A layer of dust-proof net is installed, but it still cannot prevent small particles of dust from being adsorbed on the surface of the sound film, thereby affecting the amplitude of the sound film and reducing the sound effect of electronic equipment

With the deteriorating air index in various places in recent years, the air pollution index has gradually increased, causing the electronic equipment exposed to the air to be seriously threatened by dust. At the same time, it is difficult to remove the dust particles adsorbed on the surface of the sound film. Corrosion of the sound film, it can be seen that the damage to the sound film surface caused by dust is difficult to repair

In addition, to solve the problem of sound film damage, the common technical means is to replace the audio device, which not only increases the maintenance cost, but also takes time
