Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling three-dimensional multi-layer speaker arrangements are inefficient in accurately positioning sound sources in space, particularly in environments with non-parallel speaker layers, leading to complex calculations and potential sound localization issues.
Innovation Solution
A method that divides the three-dimensional sound positioning into two-dimensional calculations using a two-dimensional calculator and a multilayer calculator, determining layer-specific speaker coefficients and gain factors to simplify the process, allowing for precise sound placement by projecting the source position into each speaker layer and accounting for geometrical setups and layer positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional sound positioning is performed using traditional methods, then sound source localization is achieved, but calculation complexity increases and positioning accuracy decreases in non-parallel speaker layer environments
Solution Approach 1:
The patent divides the three-dimensional sound positioning calculation into separate two-dimensional calculations for each speaker layer. Each layer's speakers are independently processed to determine their respective coefficients, which are then combined. This segmentation reduces calculation complexity while maintaining positioning accuracy across non-parallel speaker layer configurations.
Solution Approach 2:
The patent transforms the three-dimensional positioning problem into multiple two-dimensional problems by processing each speaker layer independently in its own plane. This dimensionality reduction simplifies the mathematical calculations required for determining speaker coefficients while preserving the ability to accurately position sounds in three-dimensional space through subsequent combination of layer results.
2Adaptability or versatility
If speaker layers are arranged in non-parallel configurations to improve spatial coverage, then audience area coverage is enhanced, but calculation complexity and positioning difficulty increase
Solution Approach 1:
The patent handles non-parallel speaker layer configurations by segmenting the calculation process into independent two-dimensional operations for each layer. Each layer's geometric configuration is processed separately to determine layer-specific coefficients, allowing the system to adapt to various speaker arrangements without increasing overall calculation difficulty.
Solution Approach 2:
The patent adapts to different speaker layer configurations by dynamically adjusting calculation parameters for each layer based on its specific geometric arrangement. The system modifies the two-dimensional calculation parameters according to each layer's orientation and speaker positions, enabling accurate sound positioning across diverse non-parallel configurations.

AI summary
A method for controlling a three-dimensional multi-layer speaker arrangement having a plurality of speakers arranged in spaced layers. The method includes: providing information for a sound to be played back from a 3D source position assigned to the sound, wherein the source position is defined with respect to a reference point (RP) within the multi-layer speaker arrangement, extracting a 2D source position (SPXY) from the source position and calculating layer specific speaker coefficients using a 2D calculator to position the sound two dimensional source position, and feeding a vertical pan or 3D source position into a multilayer calculator for obtaining a layer gain factor for each layer for obtaining speaker coefficients used as individual gains enabling the speakers to play back the sound.
