Audio Controller Dynamic Channel Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network-connected audio systems lack dynamic configuration and calibration capabilities, leading to inconsistent audio experiences across multiple speakers, especially when users move within a space or when the number of speakers changes.
Innovation Solution
A system and method that utilize a controller device to dynamically determine and implement channel configurations for network-connected audio output devices, allowing for real-time adjustments based on user preferences, speaker additions or removals, and user movement, ensuring uniform audio distribution and calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple speakers are used to output the same content, then the audio coverage area is expanded, but the audio consistency and uniformity deteriorate due to non-equidistant positioning and user movement
Solution Approach 1:
The system dynamically adjusts channel configurations and calibration parameters in real-time based on detected user position and environmental conditions. The controller continuously monitors and modifies audio output parameters to maintain consistency across multiple speakers as users move through the space, transforming a static audio system into an adaptive one.
Solution Approach 2:
The system changes audio parameters such as volume levels, delay times, and channel assignments based on detected user position and environmental feedback. By dynamically adjusting these parameters, the system maintains audio consistency and uniformity across multiple speakers even when users are not equidistant from each speaker.
2Adaptability or versatility
If the number of speakers is changed dynamically, then the system adaptability is improved, but the configuration complexity increases
Solution Approach 1:
The system performs self-configuration and self-calibration when speakers are added or removed from the network. The controller automatically detects changes in the speaker network, determines appropriate channel configurations, and adjusts calibration parameters without requiring manual user intervention, thereby simplifying the user experience while maintaining high adaptability.
Solution Approach 2:
The system uses feedback from the network configuration status and environmental sensors to automatically adjust speaker assignments and calibration settings. This closed-loop approach allows the system to adapt to changing numbers of speakers while maintaining optimal performance without increasing user-facing complexity.
3Manufacturing precision
If channel configuration is adjusted in real-time, then the audio experience quality is improved, but the processing requirements and system complexity increase
Solution Approach 1:
The controller acts as an intermediary device that centralizes the processing and calculation of channel configurations and calibration parameters. By concentrating the computational complexity in a dedicated controller rather than distributing it across all speakers, the system achieves high audio quality through real-time adjustments while keeping individual speaker devices simple.

AI summary
Multiple audio output devices are individually triggered to generate an acoustic identification signal. A controller device can perform a comparison of the acoustic identification signal from each of the multiple audio output devices. The output from one or multiple audio output devices is controlled based on the comparison.
