Dual Microphone Audio Segmentation for Simultaneous Video and Call Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices cannot execute video and call functions simultaneously without interference or distortion due to the need to stop video or voice recording when an incoming call arrives.
Innovation Solution
An electronic device with a processor unit that operates multiple microphones to selectively control voice signals, allowing for simultaneous video and call functions by processing and storing voice signals from both microphones, and sending the appropriate signals for communication, thereby eliminating interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device stops video or voice recording to answer an incoming call, then the call function can be executed, but the video recording function is interrupted
Solution Approach 1:
The patent divides the single microphone resource into two separate microphones (first microphone for video recording, second microphone for call function). This segmentation allows both video recording and call functions to operate simultaneously with dedicated audio capture channels, eliminating the need to interrupt video recording when an incoming call arrives.
2Device complexity
If the electronic device uses a single microphone for both video recording and call function, then the device complexity is reduced, but voice signal interference and distortion occur
Solution Approach 1:
The patent segments the audio capture function into two separate microphones, with the first microphone dedicated to video recording and the second microphone dedicated to call functions. This physical separation eliminates voice signal interference and distortion that would occur with a shared microphone, ensuring high-quality audio for both functions simultaneously.
Solution Approach 2:
The patent assigns different quality requirements to different audio capture scenarios. The first microphone is optimized for video recording quality, while the second microphone is optimized for call function quality. This local quality differentiation ensures that each function receives audio input tailored to its specific requirements, preventing interference and distortion.
3Productivity
If the electronic device executes video and call functions simultaneously, then the productivity is improved, but voice signal interference and distortion occur
Solution Approach 1:
The patent enables simultaneous execution of video and call functions by segmenting the audio capture resources into two separate microphones. The first microphone captures audio for video recording while the second microphone captures audio for call functions, allowing both functions to run concurrently without voice signal interference or distortion.

AI summary
A method for controlling an electronic device is provided. The method for controlling an electronic device includes operating a first microphone and a second microphone; receiving a first voice signal picked up by the first microphone and a second voice signal picked up by the second microphone; selecting at least one voice signal; storing the selected at least one voice signal; and sending the second voice signal picked up by the second microphone to a communication module.
