Embodiment 1

[0018] refer to figure 1 , shows a flow chart of steps of a dust removal method of the present invention.

[0019] The dedusting method that the embodiment of the present invention provides comprises the following steps:

[0020] Step 101: When a dust removal control operation is received, control the dust-proof net to release charges for a first preset duration.

[0021] Wherein, the dust-proof net is a conductive dust-proof net, and the dust-proof net is arranged inside the mobile terminal.

[0022] In this embodiment, the mobile terminal can be a mobile phone, a tablet computer or other mobile terminals with an audio diaphragm and a dust-proof net covering the audio diaphragm and capable of outputting audio. Do limit.

[0023] In this embodiment, there are many methods for receiving the dust removal control operation. For example, a physical button is provided on the mobile terminal. When it is detected that the physical button is pressed, the dust removal control operat...

Embodiment 2

[0030] refer to figure 2 , shows a flow chart of the steps of a dust removal method in Embodiment 2 of the present invention.

[0031] The dedusting method that the embodiment of the present invention provides comprises the following steps:

[0032] Step 201: When receiving a dust removal control operation, control the first switch to close for a first preset time period.

[0033] Wherein, when the first switch is closed, the dust-proof net releases electric charge.

[0034] like image 3 As shown, a schematic diagram of a dust removal circuit, the mobile terminal includes a ground terminal 01 , a first switch 02 , a dust filter 03 , a second switch 04 and a power module 05 connected in series.

[0035] It should be noted that, when the mobile terminal is in the non-dust removal mode, the dust filter is in an uncharged mode, that is, both the first switch and the first switch are off or the first switch is on and the second switch is off.

[0036] In this embodiment, ther...

Embodiment 3

[0049] refer to Figure 4 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0050] The mobile terminal provided by the embodiment of the present invention includes: a receiving module 301, configured to control the dust-proof net to release a charge of a first preset duration when receiving a dust-removal control operation, wherein the dust-proof net is a conductive dust-proof net, And the dust-proof net is arranged inside the mobile terminal; the control module 302 is configured to charge the dust-proof net after the first preset period of time, wherein, after releasing the charge to the dust-proof net During the charging and charging process, the dust-proof net is dedusted.

[0051] In the embodiment of the present invention, when the dust removal control operation is received, the dust-proof net is controlled to release the charge of the first preset duration, and after the preset duration, the dust-proof net is c...

Abstract

The embodiment of the invention provides a dust removing method and a mobile terminal. The dust removing method comprises the steps of controlling a dust screen to release charges for a first preset time when receiving a dust removing control operation, and charging the dust screen after the preset time. Dust removing is performed on the dust screen both in the charge releasing and charging process for the dust screen. Firstly, the dust screen is controlled to release charges, thereby being capable of eliminating the electric property of part of the dust, and thus cleaning part of the dust; secondly, a charging operation is performed on the dust screen, thereby cleaning charged impurities in the dust screen; and finally the dust removing for the dust screen is completed. The dust removingscheme provided by the embodiment of the invention can automatically clean the dust of the dust screen without disassembling the whole machine, thereby facilitating users to use.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a dust removal method and a mobile terminal. Background technique [0002] With the development of science and technology, mobile terminals have become more and more popular tools for people. There will be more or less dust and other tiny particles in the environment where the mobile terminal is used. After a long time of use, a large amount of dust will enter the mobile terminal through the sound outlet or sound inlet of the mobile terminal and adhere to the sound outlet. The dust-proof mesh of the hole and the sound inlet hole may be blocked in the dust-proof mesh hole, which will eventually affect the normal operation of the microphone, receiver and speaker of the mobile terminal. [0003] At present, the cleaning of the dust-proof nets of microphones, receivers, and speakers is generally done after the mobile terminal is disassembled. This cleaning method is complic...
