Earphone Bracket Channel Layout for Wind Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
True wireless stereo earphones with wind noise conducting tubes have a large size specification, which diminishes the appearance and hinders lightweight design, degrading user experience.
Innovation Solution
An earphone design featuring a bracket with a T-shaped channel that includes a slot section and a hole section, sealed by the housing, allowing airflow to enter and exit through separate holes, reducing wind noise and maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a wind noise conducting tube is designed with open ends to reduce wind noise, then wind noise reduction is improved, but the housing thickness increases and overall device size increases
Solution Approach 1:
The wind noise conducting tube is nested within the handle structure, with the tube positioned inside the handle's internal cavity. This allows the wind noise reduction function to be integrated without increasing the external dimensions of the earphone handle, resolving the contradiction between wind noise protection and compact size.
2Object-affected harmful factors
If the housing is thickened to accommodate the wind noise conducting tube structure, then wind noise reduction is improved, but the appearance and refinement are diminished
Solution Approach 1:
The conducting tube is nested within the existing handle structure, utilizing the internal space rather than expanding the external form. This maintains the sleek, refined appearance of the earphone while still providing effective wind noise reduction through the tube structure.
3Object-affected harmful factors
If the housing is thickened to provide structural support for the wind noise conducting tube, then wind noise reduction is improved, but the earphone weight increases
Solution Approach 1:
The wind noise conducting tube is nested within the existing handle structure, utilizing available internal space rather than requiring additional material. This integration approach provides wind noise protection without significantly increasing the overall weight of the earphone.
