Sound Box Position Detection for Automatic Audio Channel Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of configuring audio channel roles for multiple sound boxes in a stereo sound box system is tedious and complex due to the need for precise placement based on preconfigured audio channel role information, which is often limited by the configuration person's capacity and experience.
Innovation Solution
A method for determining audio channel roles of sound boxes by obtaining distance information and indication information to accurately determine the relative locations of multiple sound boxes, allowing them to be freely placed without preconfigured roles, and then configuring their roles based on these determinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio channel role information is preconfigured and marked on each sound box, then the audio channel configuration is accurate, but the configuration process becomes tedious and complex
Solution Approach 1:
The sound boxes automatically determine their own audio channel roles through wireless communication and position detection, eliminating the need for manual configuration. The system performs self-identification and self-assignment of channel roles based on detected positions, making the configuration process automatic and simple.
Solution Approach 2:
The patent replaces the mechanical marking system with a wireless communication-based automatic identification system. Instead of physical marks on sound boxes, the system uses wireless signals for position detection and automatic role assignment, simplifying the configuration process while maintaining accuracy.
2Reliability
If sound boxes are placed at corresponding locations based on preconfigured audio channel role information, then the stereo sound box system is formed correctly, but the flexibility of using sound boxes is reduced
Solution Approach 1:
The system dynamically determines audio channel roles based on the actual positions of sound boxes rather than relying on fixed preconfigured roles. The audio channel role assignment is dynamic and adapts to different placement configurations, allowing flexible arrangement while ensuring correct system formation.
Solution Approach 2:
The patent changes the parameter of audio channel role assignment from fixed (preconfigured) to variable (position-based). The system detects the positions of sound boxes and dynamically assigns roles according to their actual locations, enabling flexible placement while maintaining reliable stereo sound box system formation.
3Ease of manufacture
If audio channel role information is marked on each sound box, then the configuration process is straightforward, but the capacity and experience requirements of the configuration person increase
Solution Approach 1:
The sound boxes perform self-identification and self-configuration of audio channel roles through wireless communication. The system automatically detects positions and assigns roles without requiring configuration personnel to have specialized knowledge or experience, reducing the capability requirements while maintaining ease of configuration.

AI summary
A method and system for determining an audio channel role of a sound box. The method includes: obtaining first distance information between a first sound box and M second sound boxes; obtaining second distance information between one second sound box and at least two other second sound boxes in the M second sound boxes; and determining audio channel role information of the first sound box and the M second sound boxes based on the first distance information, the second distance information, and first indication information. The first indication information is used to indicate relative locations of the first sound box and any of the M second sound boxes, and M is an integer greater than 1.
