Bluetooth Headphone Relay Chain for Multi-User Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth headphone data transmission methods are limited and cannot satisfactorily meet user requirements for multi-person conferencing, as they lack efficient audio data transmission and identification protocols between multiple devices.
Innovation Solution
A data transmission method and system where Bluetooth headphones are connected in sequence over Bluetooth, allowing for the acquisition and conversion of sound signals into audio data, mixing of data from adjacent headphones, and transmission in opposite directions, with identity verification to determine playback or forwarding of audio data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth headphones are connected in sequence to enable multi-person conferencing, then the adaptability for multi-user scenarios is improved, but the device complexity increases due to multiple connection management requirements
Solution Approach 1:
The system segments the audio data transmission by creating separate transmission directions (first direction from mobile terminal through headphones 1-3 to headphone 4, and second direction from headphone 4 back to mobile terminal). This segmentation allows each Bluetooth headphone to independently manage audio data flow in specific directions, reducing overall connection management complexity while maintaining multi-person conferencing capability.
Solution Approach 2:
Bluetooth headphones 1-3 act as intermediaries in the audio data transmission chain. They receive audio data from the mobile terminal, mix it with locally captured audio, and forward it to the next headphone in sequence. This intermediary role simplifies the overall system architecture by creating a structured relay mechanism rather than requiring direct peer-to-peer connections between all devices.
2Area of stationary object
If audio data is transmitted through multiple Bluetooth headphones in sequence, then the coverage for multi-user communication is improved, but the transmission time increases due to multiple relay hops
Solution Approach 1:
The system maintains continuous audio data transmission through the relay chain by ensuring that each Bluetooth headphone continuously receives, mixes, and forwards audio data without interruption. The parallel operation of multiple transmission paths (first and second directions) ensures that audio data flows continuously through all headphones simultaneously, expanding coverage while minimizing transmission delays through efficient parallel processing.
3Adaptability or versatility
If Bluetooth headphones mix and forward audio data from multiple sources, then the functionality for multi-person conferencing is improved, but the processing complexity at each device increases
Solution Approach 1:
The audio processing function is segmented across multiple Bluetooth headphones, with each headphone responsible for mixing audio data from specific sources and forwarding it in a designated direction. This segmentation distributes the processing complexity across the network rather than concentrating it in a single device, allowing each headphone to perform simpler mixing operations while achieving complex multi-person conferencing functionality collectively.
