Solution Overview

Problem

Existing vibration isolation and damping devices for audio equipment face challenges with structural stability, wear, and degradation due to the use of viscoelastic materials with high shape factors, which compromise vibration isolation and damping performance.

Innovation Solution

A vibration damper design featuring a low shape factor viscoelastic material supported by a housing with bracing surfaces that allow the viscoelastic material to deform effectively while providing structural support, maintaining stability and longevity.

AI summary

A vibration damper includes a housing defining a cavity and configured to retain a viscoelastic ring, where the housing includes a first portion having a first surface and a second surface, where the second surface is configured to engage with a first loaded surface of the viscoelastic ring, a second portion having an additional first surface and an additional second surface, where the additional second surface is configured to engage with a second loaded surface of the viscoelastic ring. The housing further includes a plurality of bracing surfaces extending from a third surface of the first portion, where each bracing surface is configured to engage with a first unloaded surface of the viscoelastic ring during deformation of the viscoelastic ring within the cavity.
