Audio Signal Distribution via Dual Communication Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently outputting audio signals to multiple external devices via wireless communication, particularly in scenarios where simultaneous audio playback across different devices is desired without compromising signal quality or requiring complex configuration.
Innovation Solution
An electronic device equipped with a communication circuit supporting multiple communication schemes establishes separate communication channels to enable audio data transmission to one external device while allowing another external device to 'sniff' and reproduce the same audio signal using configuration information received through a different communication channel, facilitating simultaneous audio output across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio data is transmitted to multiple external devices simultaneously through the same communication channel, then audio signal distribution is achieved, but signal quality deteriorates and device complexity increases
Solution Approach 1:
The patent divides the audio transmission process into two separate communication channels: one for transmitting audio data and another for transmitting configuration information. This segmentation allows simultaneous transmission to multiple devices without interference, maintaining signal quality while enabling efficient distribution.
Solution Approach 2:
The patent introduces configuration information as an intermediary element that enables second external devices to acquire audio data indirectly through sniffing the first communication channel, rather than requiring direct simultaneous transmission to all devices.
2Adaptability or versatility
If configuration information is transmitted to enable sniffing by second external devices, then audio output versatility is improved, but communication channel complexity increases
Solution Approach 1:
The second communication channel serves multiple functions: transmitting configuration information to second external devices, enabling them to sniff audio data from the first channel, and facilitating synchronized audio output across multiple devices without requiring separate dedicated channels for each function.
3Ease of operation
If audio data is transmitted through a single communication channel to multiple devices, then transmission simplicity is maintained, but device synchronization capability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where second external devices receive configuration information through the second communication channel that enables them to synchronize their audio playback with the first external devices by sniffing the audio data transmitted through the first communication channel, ensuring synchronized output across all devices.
