Wireless Earphone Direct Voice Communication via Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless earphones with voice communication functions are unable to facilitate voice communication outside the coverage area of a communication base station, limiting their use in areas like airplanes or specific zones where radio wave transmission and reception are impossible.
Innovation Solution
A wireless earphone system that pairs with a mobile device and allows direct voice signal transmission and reception between paired earphones using a short-distance wireless communication method like Wi-Fi or Bluetooth, eliminating the need for mobile device intervention within a coverage area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless earphones use conventional mobile device communication for voice calls, then voice communication function is provided, but communication is limited to base station coverage areas only
Solution Approach 1:
The patent introduces a short-distance wireless communication module as an intermediary communication channel between earphones. When base station communication is unavailable, the earphones automatically switch to direct peer-to-peer communication via this intermediary module, ensuring continuous voice communication capability without requiring mobile device intervention.
Solution Approach 2:
The system dynamically switches between two communication modes: conventional base station communication through mobile devices and direct short-distance wireless communication between earphones. The communication path is not fixed but adapts based on availability, allowing the system to maintain voice communication functionality across different environments and coverage areas.
2Reliability
If wireless earphones enable direct peer-to-peer communication, then communication availability is improved, but device complexity increases
Solution Approach 1:
The patent combines the conventional mobile device communication module and the short-distance wireless communication module into a single integrated communication system. Both communication capabilities coexist within the same earphone device, sharing common components such as the microphone, speaker, and audio processing circuits, thereby reducing overall system complexity despite adding functionality.
Solution Approach 2:
The earphones perform automatic pairing and automatic mode switching between communication channels without requiring user intervention. The system autonomously manages the complexity of dual communication modes by implementing self-service functions such as automatic connection establishment, automatic authentication, and automatic fallback when one channel becomes unavailable.
3Ease of operation
If pairing is performed automatically between earphones, then ease of operation is improved, but security risk increases
Solution Approach 1:
The patent implements preliminary authentication through pre-shared passwords or unique identifiers that are established before actual communication begins. During the automatic pairing process, the earphones verify each other's authentication credentials in advance, ensuring that only authorized devices can establish direct communication links, thus preventing unauthorized access while maintaining automatic pairing convenience.
