Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active noise reduction earphones often exhibit inconsistent noise reduction effects between the left and right ears due to differences in fit, leading to varying noise cancellation performance.
Innovation Solution
A method and device that obtain wearing fit information for both earphones, calculate optimal noise reduction amounts based on this information, and adjust noise reduction parameters to achieve a common noise reduction amount, ensuring consistent noise reduction effects between the two earphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual noise reduction amounts are optimized for each earphone based on fit, then noise reduction performance is improved, but consistency between left and right earphones deteriorates
Solution Approach 1:
The patent applies local quality by optimizing noise reduction parameters individually for each earphone based on its specific fit characteristics. Each earphone receives customized noise reduction settings tailored to its unique sealing and acoustic properties, allowing both earphones to achieve optimal performance despite fit differences.
Solution Approach 2:
The patent achieves equipotentiality by equalizing the noise reduction performance between left and right earphones. Through measurement and adjustment, the system ensures that both earphones operate at the same noise reduction level, creating a balanced listening experience where fit differences do not result in performance inconsistency.
2Stability of the object's composition
If noise reduction parameters are adjusted to achieve consistency, then earphone performance uniformity is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the earphone system to automatically measure its own fit characteristics and adjust noise reduction parameters accordingly. The system performs self-diagnosis through acoustic measurements and self-optimization through automated parameter adjustment, eliminating the need for manual calibration or complex external equipment.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting noise reduction settings based on measured fit characteristics. The system modifies key parameters such as noise reduction amount, frequency response characteristics, and adaptive filtering coefficients to achieve consistent performance across both earphones while maintaining simplicity.
