Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide a solution for producing homogeneous surround sound in multi-channel, multi-speaker environments, particularly when user equipment is rotating in 3D space, leading to poor audio listening experiences due to varying speaker characteristics and orientations.
Innovation Solution
A method and system that generate a position map of speakers based on their position coordinates, determine equalized audio channels for each speaker to achieve homogeneous frequencies, allocate these channels based on the position map, and adjust audio intensity accordingly to enhance surround sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple speakers with different characteristics and positions are used to provide surround sound, then the immersive audio experience is improved, but the audio homogeneity and listening quality deteriorate due to varying speaker characteristics, positions, and orientations
Solution Approach 1:
The system applies local quality by determining equalized audio channels for each individual speaker based on its specific position coordinates and characteristics. Each speaker receives customized audio processing parameters tailored to its location in the 3D space, ensuring that despite differences in speaker characteristics and positions, the overall audio output achieves homogeneity. This is implemented through the processor that determines equalized audio channels for each speaker based on position map data.
Solution Approach 2:
The system changes parameters by adjusting audio intensity and equalized audio channels for each speaker based on its position coordinates and characteristics. The processor dynamically modifies audio parameters including intensity levels and frequency equalization to compensate for variations in speaker positions, orientations, and individual characteristics, thereby achieving homogeneous surround sound output across all speakers.
2Adaptability or versatility
If the user equipment rotates in 3D space to provide audio signals to multiple speakers, then the versatility of the system is improved, but audio lag and listening quality deteriorate
Solution Approach 1:
The system performs preliminary action by pre-determining the position map of all speakers and pre-calculating equalized audio channels before audio playback. The processor determines the positions and orientations of all speakers in advance, creates a position map, and pre-processes audio channels based on these predetermined parameters. This preliminary preparation eliminates delays that would occur during real-time rotation and audio routing, thus preventing audio lag while maintaining 3D rotation versatility.
3Area of stationary object
If speakers are positioned at different locations and orientations in the room, then the surround sound coverage is improved, but the audio listening experience deteriorates due to positioning errors and heterogeneous speaker characteristics
Solution Approach 1:
The system implements feedback by using position coordinates of each speaker to determine equalized audio channels and adjust audio intensity. The processor continuously references the position map data to ensure that audio signals are appropriately routed and equalized for each speaker's specific location and orientation. This feedback mechanism ensures that even with positioning variations, the audio listening quality remains reliable and homogeneous across the entire sound coverage area.
