Wireless Earphone Network Switching for Continuous Audio Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless headphones are either cumbersome due to cords or large in size, and lack the ability to seamlessly transition between ad hoc and infrastructure wireless networks, limiting their range and usability.
Innovation Solution
A wireless earphone with a transceiver circuit that automatically transitions between ad hoc and infrastructure wireless networks, allowing seamless audio streaming by connecting to a host server if the direct network is out of range, and featuring a compact design suitable for in-ear or over-ear configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless headphones use ad hoc network for direct connection, then audio quality is improved, but connection range is limited
Solution Approach 1:
The patent introduces an infrastructure wireless network as an intermediary when direct ad hoc connection is unavailable. The system automatically switches to infrastructure mode, connecting through access points to maintain audio streaming, thus extending connection range while preserving audio quality through the mediator network infrastructure.
Solution Approach 2:
The system dynamically switches between ad hoc and infrastructure network modes based on availability. The wireless headphones and data source automatically transition between connection types, optimizing both audio quality and connection range by adapting to environmental conditions in real-time.
2Adaptability or versatility
If wireless headphones support both ad hoc and infrastructure networks, then adaptability is improved, but device complexity is increased
Solution Approach 1:
The wireless headphones are designed with multi-functionality to support both ad hoc and infrastructure network modes. This universal design allows the device to adapt to different network environments without requiring separate dedicated devices, achieving network compatibility while managing complexity through integrated dual-mode capability.
Solution Approach 2:
The system automatically manages network mode selection and switching without user intervention. The wireless headphones and data source self-service by detecting network availability and autonomously transitioning between ad hoc and infrastructure modes, reducing the perceived complexity for users while maintaining adaptability.
3Ease of operation
If automatic network transition is implemented, then ease of operation is improved, but device complexity is increased
Solution Approach 1:
The automatic network transition feature allows the system to self-manage connectivity without user intervention. The wireless headphones and data source automatically detect when ad hoc network is unavailable and switch to infrastructure mode, providing ease of operation by eliminating manual configuration while the underlying complexity is handled by the system's autonomous control mechanisms.
Data Source
AI summary
A wireless earphone that comprises a transceiver circuit for receiving streaming audio from a data source over a local ad hoc wireless network. When the data source and the earphone are out of range, they transition automatically to an infrastructure wireless network. If there is no common infrastructure wireless network for both the data source and the speakerphone set, the earphone connects to a host server via an available wireless network.
