Wireless Earphone Battery Ratio Control for Stereo Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double-ear separate type wireless earphones often experience battery voltage discrepancies, leading to one earpiece turning off prematurely, disrupting stereo music playback due to uneven battery levels.
Innovation Solution
A method and device for dynamically distributing work between paired wireless earpieces through wireless communication, involving a control circuit that compares battery levels and adjusts operations based on reference ratios to ensure balanced performance and extended battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each earpiece operates independently with its own battery, then wireless freedom and stereo audio capability are improved, but battery voltage discrepancies cause one earpiece to turn off prematurely, worsening audio continuity
Solution Approach 1:
The patent merges the power management functions of both earpieces by designating one earpiece as the slave device that references the master device's battery level. This combination approach allows the system to operate based on the higher battery level, preventing premature shutdown and maintaining audio continuity while preserving stereo capability.
2Loss of energy
If the earpiece with lower battery voltage is turned off first to conserve energy, then energy management is improved, but stereo music playback is disrupted, worsening user experience
Solution Approach 1:
The system implements self-service power management where the slave earpiece autonomously references the master earpiece's battery level and adjusts its operation accordingly. This automatic coordination eliminates the need for manual intervention and ensures both earpieces operate harmoniously, maintaining music playback continuity while optimizing energy usage.
3Device complexity
If work distribution between earpieces is fixed, then system simplicity is improved, but uneven battery levels cause premature shutdown, worsening operational duration
Solution Approach 1:
The patent implements dynamic work distribution where the slave earpiece's operation is adaptively adjusted based on the master earpiece's real-time battery level. This dynamic approach allows the system to flexibly allocate workload, extending operational duration by preventing premature shutdown while maintaining relatively simple control architecture through role assignment.
