Wire Rope Shock Mount for Microphone Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Highly sensitive microphones are prone to picking up unwanted vibrations, leading to audible noise due to their sensitivity to mechanical vibrations, especially along the axis of the diaphragm, and existing elastomeric shock-mounting solutions have limitations such as wear and tear and accidental loosening.
Innovation Solution
A shock mount design using non-elastic flexible wire ropes to suspend the microphone, providing effective vibration isolation by absorbing energy through displacement and friction, offering a durable and long-lasting solution that does not stretch like elastomeric materials, thus reducing unwanted noise across subsonic and audible frequency ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastomeric materials are used for shock mounting, then vibration isolation is provided, but the materials wear out over time and must be replaced frequently
Solution Approach 1:
The patent changes the material parameter from elastomeric (elastic) to wire rope (non-elastic flexible), fundamentally altering the shock mounting mechanism from elastic deformation to friction-based energy dissipation, thereby eliminating wear and extending service life
Solution Approach 2:
The invention uses a composite structure combining rigid wire rope elements with flexible positioning capabilities, creating a hybrid system that provides both durability and vibration isolation through friction-based damping rather than elastic material deformation
2Measurement precision
If highly sensitive transducers are used, then audio quality is improved, but the microphones become highly sensitive to vibration producing audible noise
Solution Approach 1:
The wire rope shock mount acts as an intermediary element between the microphone and the mounting structure, providing mechanical isolation through friction-based damping that reduces vibration transmission to the sensitive transducer while maintaining audio quality
3Duration of action of moving object
If non-elastic flexible wire ropes are used, then durability and resistance to wear are improved, but the mechanism for energy absorption must rely on friction and displacement
Solution Approach 1:
The wire rope shock mount is designed to be self-adjusting, where the friction and displacement mechanisms automatically adapt to different vibration conditions without requiring external control or complex active components, providing passive energy dissipation through the inherent properties of the wire rope construction

AI summary
A shock mount for a microphone comprises a first frame member having an upper ring-shaped frame member and a lower ring-shaped frame member. The lower frame member has a microphone mount for receiving a microphone. The shock mount also has a second frame member comprising a ring. The first frame member is suspended from the second member by wire rope or other substantially non-elastic flexible material, and the wire rope is configured to help reduce the amount of vibration encountered by the first frame member. A method comprises providing a first frame member and a second frame member and suspending the first frame member from the second frame member by wire rope or other substantially non-elastic flexible material and mounting a microphone on the first frame member to help reduce the amount of vibration encountered by the first frame member and the microphone.
