Electronic Device Microphone Audio Capture Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices typically rely solely on external microphones for sound recording during image capture, neglecting ambient and peripheral noises that internal microphones are more sensitive to, resulting in incomplete audio capture.
Innovation Solution
An electronic device configuration that activates both internal and external microphones, adjusts their recording levels based on audio information, and displays sound level adjustments to the user, allowing for balanced audio capture and improved image capture control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only external microphones are used for sound recording during image capture, then the device structure remains simple, but ambient and peripheral noises are not recorded completely
Solution Approach 1:
The patent combines multiple microphone sources (internal microphones of the electronic device and external microphones from connected devices) into a unified audio recording system. The processor receives audio information from both internal and external microphones simultaneously, merging their capture capabilities to achieve complete ambient sound recording while maintaining manageable system complexity through integrated control.
2Reliability
If both internal and external microphones are activated, then audio diversity is enhanced, but the device complexity increases
Solution Approach 1:
The system implements self-service through automatic recording level adjustment. The processor automatically adjusts the recording levels of internal and external microphones based on real-time audio information analysis, eliminating the need for manual user configuration. This self-adjusting mechanism maintains high audio capture quality while reducing operational complexity for users.
Solution Approach 2:
The patent incorporates feedback mechanisms where the processor continuously monitors audio information from multiple microphones and automatically adjusts recording levels based on the captured sound quality. This closed-loop feedback system ensures optimal audio capture from both internal and external microphones without requiring complex manual intervention, as the system self-regulates based on real-time performance.
