Loudspeaker Dustproof Net Cleaning via Dynamic Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust and liquid accumulation on the dustproof net of a speaker can block the sound hole, reducing sound volume and quality, as existing solutions require disassembly of the device for cleaning.
Innovation Solution
A method and apparatus that use a built-in vibration device to clear dust or debris from the dustproof net by playing a preset audio source file, adjusting vibration intensity over time to effectively clear blockages without disassembling the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dustproof net is installed on the speaker sound hole to prevent dust and liquid entry, then the speaker is protected from blockage, but dust and liquid accumulate on the dustproof net causing it to become blocked over time
Solution Approach 1:
The vibration device, which is already present in the terminal device for other functions, is utilized to clear the dustproof net. The system performs self-maintenance by using its own existing components to remove accumulated dust and liquid, eliminating the need for external cleaning tools or device disassembly.
Solution Approach 2:
The vibration device generates mechanical vibrations that are transmitted to the dustproof net, causing accumulated dust and liquid to detach and fall off. This mechanical vibration effect effectively clears the blockage without requiring the dustproof net to be removed or the device to be disassembled.
2Ease of operation
If the device is disassembled to clean the dustproof net, then blockages can be removed effectively, but the operation becomes complex and time-consuming
Solution Approach 1:
The system maintains itself automatically using built-in components. The vibration device, already integrated into the terminal device, is activated to clear the dustproof net, transforming a complex manual cleaning process into a simple automated operation that requires no disassembly.
Solution Approach 2:
The vibration device serves multiple functions: it not only performs its original function (such as haptic feedback) but also acts as a cleaning mechanism for the dustproof net. This multi-functionality eliminates the need for separate cleaning tools or procedures.
3Productivity
If the vibration intensity is increased to clear severe blockages, then cleaning effectiveness improves, but the risk of damaging the dustproof net or speaker increases
Solution Approach 1:
The vibration intensity is made dynamic rather than static. The system adjusts the vibration parameters based on the detected blockage severity, starting with lower intensity and increasing only when necessary. This dynamic adjustment ensures effective clearing while preventing damage to the dustproof net.
Solution Approach 2:
The vibration parameters (intensity, frequency, duration) are changed according to the cleaning needs. By adjusting these parameters, the system can effectively remove blockages of varying severity while maintaining safety margins that prevent damage to the dustproof net and speaker components.

AI summary
Provided are a method and apparatus for dealing with the blockage of ventilation holes of a loudspeaker, and a terminal device. The method comprises: detecting whether ventilation holes of a loudspeaker are blocked, and prompting the user not to block the ventilation holes of the loudspeaker with a hand; and if it is learned, through detection, that the ventilation holes of the loudspeaker are blocked, playing a built-in sound source file, driving a pre-set vibration apparatus to vibrate according to a set vibration intensity, and cleaning away foreign matter blocking the ventilation holes of the loudspeaker. By means of the present application, when a dustproof mesh fabric is blocked by dust, liquid, etc., the automatic cleaning of dust or debris on the dustproof mesh fabric can be realized without disassembly, thereby reducing the difficulty of dealing with same, and improving the user experience.
