Dynamic Audio Configuration for User-Tracking IHS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern information handling systems, such as large form factor foldable PCs, face challenges in providing optimal audio and voice user experiences due to varying user locations and distances, which affect the configuration of speaker and microphone arrays, leading to suboptimal sound quality and efficiency.
Innovation Solution
An audio management computing module identifies user locations using cameras and mobile devices, dynamically configuring speaker and microphone arrays by adjusting frequencies, powers, and gain settings based on user position and distance to optimize audio output and beamforming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker array configuration is fixed, then the device complexity is reduced, but the audio quality deteriorates when user location varies
Solution Approach 1:
The speaker array configuration is made dynamic by continuously adjusting frequency distribution and power levels based on real-time user location detection. The system transitions from a fixed configuration to an adaptive one that responds to user movement, thereby maintaining audio quality without requiring multiple physical speaker sets.
Solution Approach 2:
The system changes acoustic parameters (frequency distribution, power levels) of the speaker array based on detected user location. By modifying these parameters dynamically, the system optimizes audio quality for different user positions without increasing physical device complexity.
2Area of stationary object
If the speaker power is increased to cover larger distances, then the audio coverage area is improved, but the energy consumption increases
Solution Approach 1:
Instead of uniformly increasing power across all speakers, the system applies power optimization locally by adjusting individual speaker power levels based on user direction and distance. Speakers facing the user receive higher power allocation while others reduce power, achieving efficient energy distribution across the coverage area.
Solution Approach 2:
The speaker power configuration transitions from a static high-power state to a dynamic state that adjusts power levels in real-time based on user location. This dynamic adjustment allows the system to maintain adequate audio coverage while significantly reducing energy consumption when full power is not needed.
3Adaptability or versatility
If the audio system continuously monitors user location, then the adaptability to user position is improved, but the processing requirements and complexity increase
Solution Approach 1:
The audio system performs self-adjustment by automatically detecting user location and reconfiguring speaker parameters without requiring manual intervention or complex external control systems. This self-service capability achieves high adaptability while minimizing the complexity of external monitoring infrastructure.
Solution Approach 2:
The system integrates multiple functions (user detection, location tracking, audio configuration) into a unified audio management process. By making the audio system multi-functional, it achieves high adaptability to user position while reducing overall system complexity through functional integration rather than separate dedicated components.
4Reliability
If the speaker configuration is optimized for close-range users, then the audio quality near the device is improved, but the coverage distance is reduced
Solution Approach 1:
The speaker configuration dynamically adapts between close-range optimization and long-range coverage based on detected user distance. When users are nearby, the system optimizes for high-quality close-range audio; when users move away, it transitions to a configuration that extends coverage distance, thereby resolving the trade-off between quality and range.
