Audio Speaker Coordination System Timestamp Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems with both internal and external speakers can only toggle between them or equally distribute sound, lacking the ability to coordinate and align audio signals effectively for enhanced playback experiences.
Innovation Solution
A method and system that processes and distributes audio signals between internal and external speakers, aligning timestamps to ensure synchronized playback, utilizing a processor and software/hardware modules for decoding, cooperative playback control, dynamic adjustments, and multi-channel mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound is distributed equally to both internal and external speakers, then audio playback coverage is improved, but audio signal synchronization and timing alignment deteriorates
Solution Approach 1:
The system dynamically adjusts audio parameters including timestamp alignment, volume levels, and signal distribution ratios between internal and external speakers. The processor modifies these parameters in real-time based on detected speaker connection statuses, ensuring synchronized playback while maintaining flexible audio coverage across different playback scenarios.
2Manufacturing precision
If only one set of speakers is used at a time (toggling between internal and external), then audio signal synchronization is maintained, but audio playback versatility deteriorates
Solution Approach 1:
The system transitions from static speaker selection (toggling between internal or external) to dynamic multi-speaker coordination. The processor continuously monitors connection statuses and dynamically adjusts signal distribution, timestamp alignment, and volume parameters to maintain synchronization while enabling versatile playback across single or multiple speaker configurations.
3Adaptability or versatility
If audio signal is distributed to multiple speakers simultaneously, then audio playback versatility is improved, but system complexity deteriorates
Solution Approach 1:
The system implements self-service through automatic detection of speaker connection statuses and autonomous adjustment of audio signal distribution parameters. The processor automatically determines which speakers are connected, aligns timestamps, and configures signal routing without requiring manual user setup, thereby reducing the perceived system complexity while maintaining multi-speaker playback versatility.
Data Source
AI summary
Novel methods and systems for coordinating sound to both internal and external speakers for a device is disclosed. The audio signal is distributed among the internal and external speakers and aligned so that signals going to the internal speakers are aligned with signals going to the external speakers.
