Wireless Headset-Microphone Radios for Separate Audio Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless audio devices with both audio input and output capabilities suffer from degraded audio quality due to shared communication channels, particularly when implementing hands-free communication profiles, which compromise the bandwidth and user experience.
Innovation Solution
Implementing independent wireless radios for audio input and output devices, allowing them to establish separate communication links with electronic devices, thereby avoiding depreciated communication profiles and enhancing audio quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common wireless transceiver is used for both audio input and output, then device complexity is reduced, but audio quality deteriorates due to bandwidth sharing
Solution Approach 1:
The patent divides the wireless communication system into separate transceivers: a first transceiver in the headset for audio output and a second transceiver in the microphone for audio input. This segmentation allows each transceiver to operate independently with dedicated bandwidth, preventing the audio quality degradation that occurs when both functions share a common transceiver.
2Adaptability or versatility
If hands-free communication profile is implemented, then audio transmission capability is added, but audio quality of received signals deteriorates due to bandwidth constraints
Solution Approach 1:
The patent implements separate wireless communication channels by using independent transceivers for audio input and output. This allows the system to simultaneously support hands-free communication profile for audio transmission while maintaining high-quality audio reception, as each function has dedicated bandwidth rather than competing for shared resources.
3Manufacturing precision
If independent wireless radios are implemented for audio input and output, then audio quality is improved, but device complexity increases
Solution Approach 1:
The patent extracts the audio input function into a separate microphone device with its own transceiver, while the headset retains its transceiver for audio output. This extraction resolves the complexity issue by distributing transceivers across separate devices rather than requiring a single complex transceiver to handle both functions, making the system architecture more manageable.

AI summary
Aspects of the disclosure relate to wireless audio devices with independent wireless radios. The devices may include a headset (or other audio output device(s)) and a microphone (or other audio input device(s). The wireless audio device may include respective wireless radios (e.g., transceivers) for the audio output device(s) and for the audio input device(s) configured for independent wireless communications. The independent wireless radios and corresponding independent communication links allow for both the wireless audio input and output devices to operate without using a depreciated communication profile (e.g., hands-free profile), thereby advantageously providing improved audio quality and user experience.
