Wireless Audio Monitoring Via Pseudo Sound-Source Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless audio devices with dual-channel configurations face issues of increased power consumption, data delay, and unsynchronization due to multiple data forwarding and large communication parameter exchanges, leading to poor user experience.
Innovation Solution
A primary audio device masquerades as a sound source device to establish communication links, acquiring and using its parameters to enable a secondary audio device to quickly enter a monitoring mode by establishing a pseudo connection, thereby reducing the need for direct parameter exchange and minimizing delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound source device sends audio data to the primary audio device first, and then the primary audio device forwards it to the secondary audio device, then both audio devices can receive audio data, but power consumption increases and data delay and unsynchronization occur
Solution Approach 1:
The patent segments the audio data transmission process into two independent paths: the sound source device directly transmits audio data to both the primary and secondary audio devices through separate communication links, avoiding the need for the primary device to forward data to the secondary device. This segmentation eliminates redundant data forwarding and reduces power consumption while ensuring both devices receive synchronized audio data.
2Reliability
If the primary audio device forwards audio data to the secondary audio device, then both devices can receive audio data, but data delay and unsynchronization occur between the two audio devices
Solution Approach 1:
The patent establishes independent communication links from the sound source device to both primary and secondary audio devices, segmenting the data transmission path. This allows both devices to receive audio data simultaneously without sequential forwarding delays, ensuring synchronization and reducing data delay while maintaining reliable audio data reception.
3Reliability
If the primary audio device sends all communication parameters to the secondary audio device, then the secondary device can enter monitoring mode, but the large data volume requires multiple Bluetooth interactions and prevents rapid entry into monitoring mode
Solution Approach 1:
The patent extracts only the essential communication parameters (such as connection identifiers and key authentication data) from the complete set of communication parameters and transmits them from the primary audio device to the secondary audio device. This extraction approach allows the secondary device to quickly establish monitoring mode without receiving the full parameter set, significantly reducing transmission time and enabling rapid entry into monitoring mode while maintaining reliable connection.
Solution Approach 2:
The patent performs preliminary configuration by pre-establishing the communication link between the sound source device and the secondary audio device using a monitoring mode connection identifier. This preliminary action allows the secondary device to be pre-configured with essential parameters before actual monitoring begins, reducing the time needed to enter monitoring mode while ensuring reliable connection establishment.

AI summary
A wireless audio monitoring method and a wireless audio system. The wireless audio monitoring method includes: establishing a first communication link between a primary audio device and a sound source device, so that the primary audio device acquires characteristic parameters of the sound source device; using, by the primary audio device, the characteristic parameters of the sound source device to masquerade as the sound source device and become a pseudo sound source device; establishing a second communication link between the pseudo sound source device and a secondary audio device, so that the secondary audio device acquires communication parameters of the first communication link; and monitoring, by the secondary audio device, the first communication link according to the communication parameters of the first communication link. The secondary audio device can acquire part of information in the communication parameters of the first communication link when the second communication link is established.
