Speaker Orientation Settings for Space-Constrained Surround Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems face challenges in optimally positioning speakers due to space constraints and user-specific preferences, which affect acoustic performance for video and gaming applications.
Innovation Solution
An information processing apparatus that receives and records audio output setting information, allowing users to set speaker positions relative to their orientation, and provides this information for audio signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speakers are placed around the user to enhance sense of presence, then acoustic performance is improved, but space constraints prevent ideal positioning
Solution Approach 1:
The system changes the parameters of audio output by adjusting speaker position information and audio characteristics based on user posture detection. When the user is detected to be in a non-seated posture, the system modifies audio output parameters to compensate for suboptimal speaker positioning, thereby maintaining acoustic performance despite space constraints.
2Reliability
If speaker positions are optimized for each user, then acoustic performance is improved, but system complexity increases to accommodate user-specific settings
Solution Approach 1:
The system automatically detects user posture using sensors and self-adjusts audio output settings without requiring manual user configuration. This eliminates the need for complex user-specific setup procedures while still providing optimized acoustic performance for each user's actual usage situation.
Solution Approach 2:
The system continuously monitors user posture through sensor feedback and dynamically adjusts audio output characteristics in real-time. This closed-loop feedback mechanism enables the system to adapt to changing user conditions automatically, providing optimized acoustic performance without requiring complex pre-configuration.

AI summary
An information processing apparatus processes an audio signal and is connected to a speaker system having a plurality of speakers. The information processing apparatus receives input of audio output setting information indicating the direction of each speaker of the speaker system relative to an orientation of a user, records the received audio output setting information, and outputs the recorded audio output setting information as requested for use in processing the audio signal.
