Microphone Windscreen Light Guide for LED Status Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing windscreens for microphones with light emitting parts obscure the visibility of the light emitting diodes, making it difficult for participants to recognize the operation state, while increasing the size to improve visibility hinders miniaturization and design.
Innovation Solution
A windscreen design with a light guide part that positions and guides the light from the light emitting display part outside, ensuring visibility without obstructing the sound collecting area and maintaining the microphone's miniaturization and design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a windscreen is attached to cover the sound collecting part, then pop noise is reduced, but the light emitting part is obscured and visibility is poor
Solution Approach 1:
The windscreen is divided into a sound collecting part covering portion and a light emitting part exposing portion. The light emitting part exposing portion is positioned at a location that does not obstruct the light from the light emitting part, allowing the windscreen to reduce pop noise while maintaining visibility of the operation state indicator.
2Loss of information
If the size of the light emitting part is increased to improve visibility, then the operation state is more visible, but miniaturization of the microphone is hindered
Solution Approach 1:
Instead of increasing the size of the light emitting part itself, the solution positions the light emitting part exposing portion of the windscreen at an optimized spatial location that allows light to pass through or around to the observer. This dimensional positioning approach maintains visibility without requiring an increase in the light emitting part size, thus preserving microphone miniaturization.
3Object-affected harmful factors
If the windscreen covers the light emitting part, then the sound collecting part is protected, but the speaker cannot visually recognize the operation state
Solution Approach 1:
The windscreen is segmented into distinct functional zones: a sound collecting part covering portion for wind protection and a light emitting part exposing portion for visual recognition. This segmentation allows the windscreen to simultaneously protect the microphone from wind while maintaining the speaker's ability to see the operation state indicator through the exposed light.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The windscreen provides good visibility of the light emitting part's operation state without obstructing the sound collection, allowing users to recognize the microphone's status while minimizing the impact on the microphone's size and design.
