Description

Technical Field

[0001] The present invention relates to the technical field of mobile terminals, and in particular to a cleaning method, a cleaning device and a terminal. Background Art

[0002] Currently, electronic devices mainly produce sound through the vibration of the diaphragm of the internal sound module. In order to transmit the vibration generated by the diaphragm to the user's ear through the air, it is necessary to form an opening arranged opposite to the sound module on the front panel of the electronic device. In addition, in order to prevent external dust and particles from entering the electronic device, a dustproof net is arranged at a position opposite to the opening, so that most of the dust and particles will fall on the dustproof net. When too much dust accumulates on the dustproof net, it affects the sound effect and the aesthetic appearance of the electronic device.

[0003] In the prior art, users need to manually clean the dustproof mesh at the sound outlet. In special cases, the terminal device needs to be sent to a repair center and the dustproof mesh can be manually removed after the device is disassembled. It can be seen that in the prior art, the method of removing dust from the sound outlet of the speaker is not convenient enough and the user experience is not good.

[0028] In the following description, use of suffixes such as “module”, “unit”, “element”, etc. used to indicate elements is merely for facilitating description of the present invention, and has no specific meaning by itself.

[0029] Please refer to Figure 1 , Figure 1 FIG. 1 is a flow chart of a cleaning method according to a first embodiment of the present invention.

[0030] like Figure 1 As shown, the cleaning method of the first embodiment of the present invention comprises the following steps:

[0031] Step S11: Detect the sound output channel of the speaker.

[0032] Specifically, the sound output channel of the speaker can be detected through the acoustic impedance data obtained when the audio or video is in use to determine whether the sound output channel is blocked. The user can also check whether the sound output channel of the speaker is blocked.

[0033] In one embodiment, step S11: detecting the sound output channel of the speaker, including: determining the working mode of the terminal device, the working modes including: speaker external speaker mode and headphone mode; obtaining the acoustic impedance data when the speaker is in a working state; comparing the acoustic impedance data with a preset acoustic impedance threshold of the corresponding working mode; when the acoustic impedance data is greater than the preset acoustic impedance threshold, confirming that the sound output channel of the speaker is in a blocked state.

[0034] Specifically, the database pre-stores preset acoustic impedance thresholds corresponding to the speaker external speaker mode and the headphone mode, wherein the preset acoustic impedance threshold is used to distinguish whether the sound output channel of the speaker is in a blocked state; when the collected acoustic impedance data is greater than the preset acoustic impedance threshold, it indicates that the sound output channel is blocked, and the collected acoustic impedance data is less than or equal to the preset acoustic impedance threshold, it indicates that the sound output channel is unblocked.

[0035] When it is detected that the working mode of the terminal is the speaker external mode, the acoustic impedance data collected in the current speaker external mode working state is compared with the preset acoustic impedance threshold of the speaker external mode stored in the database; when it is detected that the working mode of the terminal is the headphone mode, the acoustic impedance data collected in the current headphone mode working state is compared with the preset acoustic impedance threshold of the headphone mode stored in the database; when the collected acoustic impedance data is greater than the preset acoustic impedance data of the corresponding mode stored in the database, it is confirmed that the sound output channel of the speaker is in a blocked state.

[0036] Step S12: When the sound outlet channel is detected to be blocked, a cleaning mode selection instruction is obtained.

[0037] Specifically, after the sound output channel is detected, the user is reminded so that the user can clean the sound output channel of the speaker in time, thereby ensuring the pronunciation quality of the speaker.

[0038] In one embodiment, step S12: when the sound outlet channel is detected to be blocked, obtaining a cleaning mode selection instruction includes: when the sound outlet channel is detected to be blocked, displaying reminder information about selecting a cleaning mode.

[0039] Specifically, when the terminal compares the collected acoustic impedance data with the preset acoustic impedance threshold of the corresponding working mode in the database and confirms that the sound output channel is blocked, a reminder message is displayed to remind the user to clean the sound output channel of the speaker in time. The user can also select different cleaning modes from the reminder information to clean the sound output channel of the speaker.

[0040] In one embodiment, step S12: when the sound output channel is detected to be blocked, obtaining a cleaning mode selection instruction includes: pre-associating a preset button on the terminal with a cleaning instruction; when the sound output channel is detected to be blocked, obtaining a trigger instruction for the preset button on the terminal.

[0041] Specifically, a preset button on the terminal is associated with a cleaning instruction, and the user does not need to open an application, which reduces the user's operation steps. When the user finds that the sound channel is blocked by checking the sound channel, the sound channel cleaning function can be directly started through the preset button.

[0042] Step S13: Execute a corresponding cleaning operation according to the cleaning mode selected by the cleaning mode selection instruction.

[0043] Specifically, in one embodiment, the cleaning mode includes an automatic cleaning mode and a manual cleaning mode, wherein the automatic cleaning mode only cleans dust, iron filings and other particles in the sound output channel of the speaker, and the manual cleaning mode can clean moisture and dust, iron filings and other foreign matter in the sound output channel of the speaker. The user can select the corresponding cleaning mode according to the actual situation in the sound output channel of the speaker.

[0044] In one embodiment, step S13: performing a corresponding cleaning operation according to the cleaning mode selected by the cleaning mode selection instruction, including: when the user uses the automatic cleaning mode, converting the audio driving circuit of the speaker from a low power mode to a high power mode, and using the high power mode to play a preset sound source.

[0045] Specifically, using the high-power mode of the speaker to play the preset sound source ensures the effectiveness of vibrating and shedding foreign matter such as dust and iron filings in the sound output channel of the speaker, while the low-power mode of the speaker ensures the voice volume of normal calls.

[0046] In one embodiment, step S13: performing corresponding cleaning operations according to the cleaning mode selected by the cleaning mode selection instruction, including: when the user uses the automatic cleaning mode, converting the audio driving circuit of the speaker from a low power mode to a high power mode, and obtaining a sound source of matching frequency for playback according to the acoustic impedance data.

[0047] Specifically, using the speaker's high-power mode to play a preset sound source ensures that foreign objects such as dust and iron filings in the speaker's sound output channel are vibrated off. By searching for a sound source that matches its frequency in the database and playing it, the effectiveness of vibrating off foreign objects such as dust and iron filings in the sound output channel can be enhanced.

[0048] In one embodiment, step S13: performing a corresponding cleaning operation according to the cleaning mode selected by the cleaning mode selection instruction, including: when the user uses the manual cleaning mode, starting the heating mode, outputting a DC voltage matching the rated power of the speaker, and driving the speaker to generate heat.

[0049] Specifically, by outputting a DC voltage that matches the rated frequency of the speaker, the speaker is driven to generate heat, thereby removing moisture from the sound output channel of the speaker and keeping the sound output channel dry.

[0050] Specifically, when the user uses the manual cleaning mode, the heating mode is started, and a DC voltage matching the rated power of the speaker is output to drive the speaker to generate heat, followed by the step of converting the audio driving circuit of the speaker from a low power mode to a high power mode, and using the high power mode to play a preset sound source.

[0051] Specifically, by starting the heating mode, the moisture in the sound outlet channel is removed, and dust, iron filings, etc. are separated from the moisture, thereby ensuring the effectiveness of the removal of dust, iron filings, etc.

[0052] In one embodiment, step S13: performing a corresponding cleaning operation according to the cleaning mode selected by the cleaning mode selection instruction, and then including: re-detecting the sound output channel of the speaker; if it is detected that the sound output channel of the speaker remains blocked, prompting the user to perform maintenance.

[0053] Specifically, after cleaning through the automatic cleaning mode and / or the manual cleaning mode, the sound output channel of the speaker is re-tested to confirm that the cleaning of the sound output channel of the speaker is successful; if it is detected that the sound output channel of the speaker is still blocked, it indicates that the blockage of the sound output channel cannot be cleaned through the automatic cleaning mode and / or the manual cleaning mode, or the blockage of the sound output channel is not caused by foreign matter such as dust, iron filings, water droplets, etc.

[0054] The cleaning method provided in this embodiment determines whether the sound output channel of the speaker is in a blocked state by comparing the collected acoustic impedance data with the preset acoustic impedance threshold of the corresponding working mode stored in the database, or by the user checking the sound output channel by himself. When the sound output channel is in a blocked state, the user can select automatic cleaning mode or manual cleaning mode to clean the sound output channel of the speaker according to the actual situation in the sound output channel. This can effectively solve abnormal problems such as reduced volume and deteriorated sound quality caused by dust, iron filings and other foreign objects in the sound output channel. It can be cleaned automatically to solve the problem that the earpiece and dust screen cannot be cleaned due to small space or that cleaning easily damages the earpiece and dust screen.

[0055] Figure 2 It is a schematic structural diagram of a cleaning device according to a second embodiment of the present invention.

[0056] like Figure 2 As shown, the cleaning device according to the second embodiment of the present invention comprises: a detection module 10 , an instruction receiving module 20 and an execution module 30 .

[0057] Specifically, the detection module 10 is used to detect whether the sound output channel of the speaker is blocked; the instruction receiving module 20 is used to receive the cleaning mode selection instruction; the execution module 30 is used to perform the corresponding cleaning operation according to the cleaning mode selected by the cleaning mode selection instruction.

[0058] Specifically, the execution module 30 includes: a switching unit and a playing unit, which switches the audio driving circuit of the speaker from a low power mode to a high power mode after receiving the cleaning mode selection instruction; after performing the cleaning operation, the audio driving circuit of the speaker is switched from a high power mode to a low power mode. The playing unit is used to play a preset sound source.

[0059] The cleaning device provided in this embodiment determines whether the sound output channel of the speaker is in a blocked state by comparing the collected acoustic impedance data with the preset acoustic impedance threshold of the corresponding working mode stored in the database, or the user checks the sound output channel by himself. When the sound output channel is in a blocked state, the user can select automatic cleaning mode or manual cleaning mode to clean the sound output channel of the speaker according to the actual situation in the sound output channel. It can effectively solve abnormal problems such as reduced volume and deteriorated sound quality caused by dust, iron filings and other foreign objects in the sound output channel. It can automatically clean and solve the problem that the earpiece and dust screen cannot be cleaned due to small space or cleaning is easy to damage.
