Vibratory Isolation
Introduction
In a variety of applications, a floating mount is a type of mechanical mount that connects two parts elastically.
In the case of a microphone the main part of the floating mount is an outer elastic frame. This helps reduce mechanically coupled noise from the surrounding area, without affecting the sound of the microphone.
In high-gain amplifiers, design engineers used to mount the tube-socket assembly of these stages, shake-proof, using small tandem rubber bands placed in the screw holes, leaving the tube-socket assembly in a "floating" situation.[1][2].
Microphones
They are commonly used in studio microphones to prevent unwanted noise. The floating mount is used to partially isolate the microphone from vibrations that might otherwise be transmitted through the microphone stand, causing unwanted sounds to be added to the output signal.
Compact Disc Players
A different design is found in some compact disc players, in which tandem rubbers support the mechanics of the disc and the reading assembly, thereby isolating them from external vibrations.
Shock mount for furniture
A similar idea, also known as shock mount, is found in furniture design, introduced by Charles and Ray Eames. The shock mount provides some shock absorption and serves as a hinge, allowing the seat to pivot freely.
