Microphone Shock Mount With Nested Suspension for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microphones are sensitive to wind noise and mechanical vibrations, with existing shock mount designs failing to adequately support the microphone and prevent vibration noise, especially in demanding situations like film sound pickup.
Innovation Solution
A microphone shock mount featuring a double suspension system with an inner and outer support frame and resilient elements that absorb external shocks and vibrations, preventing their transmission to the microphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regular microphone suspension system is used, then the microphone can be supported, but vibration noise at or close to a rubber resonant frequency is transmitted to the microphone
Solution Approach 1:
The shock mount divides the support system into multiple independent resilient elements (multiple rubber bands arranged in parallel) rather than using a single rubber ring. This segmentation creates multiple vibration isolation paths with different resonant frequencies, preventing any single resonant frequency from dominating and transmitting noise to the microphone.
Solution Approach 2:
The invention uses a nested structure where the microphone is suspended within an inner support frame, which is itself suspended within an outer support frame. This nested arrangement of multiple suspension levels creates a multi-stage vibration isolation system that progressively attenuates vibrations before they reach the microphone.
2Object-affected harmful factors
If existing shock mount designs (elastic loop or tubular shell with stretch-cord) are used, then some vibration protection is provided, but the microphone head portion is not adequately supported
Solution Approach 1:
The shock mount applies different support characteristics to different parts of the microphone system. The resilient elements are specifically positioned and configured to provide enhanced support to the microphone head portion while maintaining vibration isolation. The inner support frame structure provides localized reinforcement where the microphone head is most vulnerable to vibration damage.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents vibrations from reaching the microphone, providing stable support and reducing noise interference, even in situations where the microphone must move constantly.
Implementation Method 1
at least one resilient element having a predetermined elasticity extending between the outer support frame and the inner support frame so as to suspendedly support the inner support frame within the outer support frame

AI summary
A microphone shock mount includes a mounting base, and a shock absorption assembly. The shock absorption assembly includes an outer support frame, an inner support frame and at least one resilient element. The outer support frame has a central opening connected to and extending from the mounting base. The inner support frame is supported in the central opening of the outer support frame, and has a through supporting slot. The resilient element extends between the outer support frame and the inner support frame so as to suspendedly support the inner support frame within the outer support frame. The microphone stem is adapted to fittedly penetrate the supporting slot and to be detachably mounted on the inner support frame in such a manner that external shocks and vibrations are capable of being absorbed by the resilient element so as to effectively prevent vibrations from transmitting to the microphone.
