Speaker-Based Moisture Detection and Discharge in Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices are prone to damage or malfunction when moisture enters through openings in the housing, particularly affecting speakers and microphones, leading to potential circuit damage or corrosion.
Innovation Solution
The electronic device employs multiple speakers to identify moisture introduction and guides a tilting direction for moisture discharge, using processors to control the speakers to perform a moisture discharge function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple speakers are used to detect moisture introduction, then moisture detection accuracy is improved, but device complexity increases
Solution Approach 1:
The speakers serve dual functions: they act as both audio output devices and moisture detection sensors. By utilizing the existing speakers for both purposes, the patent avoids adding separate detection components, thereby improving moisture detection accuracy without significantly increasing device complexity
Solution Approach 2:
The speakers perform self-diagnosis by detecting changes in their own electrical characteristics when moisture is introduced. The system uses the speakers' inherent properties to detect moisture, eliminating the need for external detection mechanisms and reducing overall system complexity
2Productivity
If moisture discharge function is implemented through speakers, then moisture removal efficiency is improved, but risk of secondary damage increases
Solution Approach 1:
The system performs preliminary detection of moisture introduction using the speakers before initiating the discharge function. By detecting moisture early and guiding the user to tilt the device in the correct direction, the system prepares for safe moisture discharge and prevents secondary damage from improper discharge operations
Solution Approach 2:
The patent introduces an intermediary guidance mechanism that provides directional information to the user about how to tilt the device for safe moisture discharge. This intermediary guidance layer mediates between the moisture discharge function and the user, ensuring the discharge is performed safely without causing secondary damage
3Ease of operation
If tilting direction guidance is provided for moisture discharge, then ease of operation is improved, but information processing requirements increase
Solution Approach 1:
The system provides localized directional guidance information specific to the detected moisture location and device orientation. By tailoring the guidance information to the specific situation rather than providing generic instructions, the system improves ease of operation while minimizing unnecessary information processing
Data Source
AI summary
An electronic device is provided. The electronic device includes speakers, memory, including one or more storage media, storing instructions, and one or more processors communicatively coupled to the multiple speakers and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to in response to execution of a designated function, identify moisture introduction into at least one speaker among the multiple speakers by using the multiple speakers, output information for guiding a tilting direction of the electronic device to discharge the moisture introduced into the at least one speaker, and cause the at least one speaker to perform a moisture discharge function.
