Microphone Unit Vibration Noise Reduction via Dual-Point Elastic Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microphone devices experience vibration noise due to the microphone unit shaking back and forth when only one end is supported, leading to handling noise from contact with the microphone case.
Innovation Solution
A microphone device design where the microphone unit is supported by a plate-like elastic body fixed to two upper and lower points within the microphone case, utilizing a holding window at the center of the elastic body to securely hold the unit and prevent shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the microphone unit is supported at only one end on the base, then the structure is simple, but the microphone unit shakes back and forth when touched, generating vibration noise
Solution Approach 1:
The support structure is segmented into multiple independent support points (upper support point and lower support point) instead of a single support point. The elastic body is divided into first and second elastic portions that connect to different locations on the microphone case, creating distributed support that reduces vibration and noise while maintaining structural simplicity.
2Object-affected harmful factors
If the microphone unit is supported at multiple points, then vibration noise is reduced, but the device complexity increases
Solution Approach 1:
Multiple support functions are merged into a single integrated elastic body component. The first elastic portion and second elastic portion are combined into one continuous elastic structure that provides both upper and lower support points, reducing the number of separate parts and assembly steps while achieving effective vibration reduction.
Solution Approach 2:
The elastic body serves multiple functions simultaneously: it provides mechanical support at upper and lower points, allows for diagonal movement of the microphone unit, absorbs vibrations, and reduces noise. This multi-functionality eliminates the need for separate components for each function, maintaining structural simplicity.
3Object-affected harmful factors
If the microphone unit is rigidly fixed to prevent shaking, then vibration noise is eliminated, but the ability to absorb impacts and maintain structural unity is reduced
Solution Approach 1:
The support structure transitions from a rigid fixed connection to a dynamic elastic connection. The elastic body allows the microphone unit to move diagonally and absorb impacts while maintaining connection to the microphone case. This dynamic support eliminates vibration noise through elasticity rather than rigid constraint, preserving structural unity under impact conditions.
