Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microphones suffer from noise transmission due to vibrations and rubbing sounds when gripped, which are not adequately addressed by existing shock mounts.
Innovation Solution
A microphone design featuring a cylindrical grip with a buffer member having ribs on its outer edge and a support bush with reduced contact areas to absorb vibrations and reduce noise transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shock mount is used to support the microphone unit, then the microphone unit is supported inside the housing, but vibration transmitted through the shock mount is collected as noise by the microphone unit
Solution Approach 1:
The shock mount is divided into multiple functional zones: an elastic deformation region that absorbs vibration energy, a rib structure that distributes stress, and a support region that maintains structural integrity. This segmentation allows different parts of the shock mount to perform specialized functions in reducing noise transmission while supporting the microphone unit.
Solution Approach 2:
The shock mount features localized structural variations including ribs with specific thicknesses and spacing, and regions of varying elastic modulus. These local quality changes optimize vibration absorption at critical stress points while maintaining overall structural support capabilities, thereby reducing noise transmission without compromising support stability.
2Ease of manufacture
If the shock mount has a simple structure, then manufacturing is easier, but noise from the housing cannot be sufficiently removed
Solution Approach 1:
The shock mount design utilizes parameter optimization including rib thickness, spacing, and material elastic modulus to achieve effective noise reduction. By carefully selecting these parameters, the shock mount provides sufficient vibration absorption while maintaining a manufacturable structure that can be produced using standard manufacturing processes.
Solution Approach 2:
The shock mount employs composite construction combining materials with different elastic properties to create an effective vibration damping structure. This composite approach enables the shock mount to absorb vibrations across multiple frequency ranges while maintaining structural integrity and ease of manufacture through integrated design.
