Dynamic Audio Role Redistribution for Seamless Speaker Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio signal distribution systems fail to maintain seamless audio reproduction when the number of speakers varies, leading to interruptions or loss of audio channels when speakers are moved or disconnected.
Innovation Solution
An audio signal distribution method that assigns reproduction roles to multiple speakers and dynamically redistributes audio signals based on changes in the number of connected speakers, ensuring continuous reproduction by pairing speakers to take over the role of disconnected ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals are distributed to multiple speakers with fixed reproduction roles, then multi-channel audio reproduction is achieved, but audio reproduction interruptions occur when the number of speakers changes
Solution Approach 1:
The patent implements dynamic role reassignment where speakers can change their reproduction roles based on real-time system state. When a speaker is disconnected, the system dynamically redistributes audio channels to remaining speakers, allowing the system to adapt to varying speaker counts while maintaining continuous audio reproduction without interruptions.
Solution Approach 2:
The system changes the reproduction role parameters of speakers based on the number of active speakers detected. By monitoring system state and adjusting which speakers reproduce which audio channels dynamically, the system maintains reliable audio reproduction whether 2 or 4 speakers are connected, resolving the contradiction between fixed role assignment and flexible speaker configuration.
2Device complexity
If speakers are assigned fixed reproduction roles in advance, then audio signal distribution is simplified, but audio channels are lost when speakers are moved or disconnected
Solution Approach 1:
The system continuously monitors the connection status of speakers and uses this feedback to dynamically adjust audio signal distribution. When a speaker disconnects, the system receives feedback about the changed configuration and automatically redistributes audio channels to prevent information loss, maintaining all audio channels regardless of speaker availability.
Solution Approach 2:
The system performs preliminary role assignment but prepares for changes by enabling dynamic reassignment capability. Speakers are initially assigned roles for simplified operation, but the system pre-configures the ability to redistribute roles when disconnections occur, preventing audio channel loss without requiring complex manual reconfiguration.
3Stability of the object's composition
If the system maintains fixed speaker configuration, then reproduction roles are stable, but the system cannot adapt when speakers are carried to different locations
Solution Approach 1:
The patent implements a dynamic role assignment system that adapts to speaker mobility. When speakers are carried to different locations or disconnected, the system dynamically reassigned reproduction roles to remaining speakers, maintaining stable audio reproduction while fully adapting to changing physical configurations of the speaker system.

AI summary
An audio signal distribution method includes assigning in advance a reproduction role to each of a plurality of speakers, distributing an audio signal to the plurality of speakers, according to the reproduction role, and, in response to the number of speakers being decreased, causing a speaker paired with the released speaker on the reproduction role to further reproduce sound of the released speaker.
