In-Pocket Microphone Adjustment for Textile Noise Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in maintaining effective audio signal transmission and reception when placed in enclosed environments, such as pockets or purses, due to acoustic signal degradation and interference from textile materials, which can overwhelm microphones and affect voice recognition and hands-free functions.
Innovation Solution
The implementation of sensors and processors that detect when an electronic device is in an enclosed condition, adaptively select the least affected microphone, and apply an audio signal adjustment function through amplitude compensation and spectral equalization to enhance audio signal reception and transmission, mitigating noise and attenuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device is placed in an enclosed environment (pocket or purse), then the device is portable and convenient for user interaction, but the audio signal transmission and reception are degraded due to acoustic interference from textile materials
Solution Approach 1:
The system performs preliminary actions by detecting the enclosed condition before audio processing, then pre-applies the appropriate audio signal adjustment function to compensate for expected acoustic degradation from textile materials, ensuring reliable audio transmission despite the enclosed environment
Solution Approach 2:
The system changes audio processing parameters dynamically by selecting different audio signal adjustment functions based on the detected enclosed condition, modifying gain, frequency response, and other audio parameters to compensate for textile material interference and maintain reliable audio transmission
2Device complexity
If standard audio transducers are used without adjustment, then the device structure is simple, but the audio signal is overwhelmed by noise from textile materials in enclosed conditions
Solution Approach 1:
The system uses feedback from sensors detecting the enclosed condition to automatically select and apply the appropriate audio signal adjustment function, creating a closed-loop system that compensates for textile noise without requiring complex manual intervention or overly complicated hardware modifications
3Reliability
If the device adapts to different environments with sensor detection and signal adjustment, then audio performance in enclosed conditions is improved, but the device complexity increases due to additional sensors and processing
Solution Approach 1:
The system achieves universality by designing a multi-functional audio processing framework where sensors serve multiple purposes (environmental detection, enclosed condition detection) and a single audio signal adjustment mechanism handles various enclosed environments (pockets, purses, different textile materials), reducing overall system complexity while maintaining high reliability across different conditions

AI summary
An electronic device includes one or more microphones, one or more sensors, and one or more processors operable with the one or more microphones and the one or more sensors. The one or more processors, upon the one or more sensors detecting the electronic device is disposed within a repository container, such as a pocket, apply an audio signal adjustment function to signals received from the one or more microphones, thereby mitigating noise in the signals caused by the repository container.
