Vibration Control

I know that most everything can matter in an even decent mid fi system & noise is a real enemy of high level resolution. That said, how does minimal physical vibration create noise in a solid state electronic circuit? Any EE’s out there who understand & appreciate good audio systems??

I find this subject quite frustrating if not maddening.  It would be easy to demonstrate whether or not vibration control is necessary or not with a variety of solid state components and yet... I've yet to see this happen.  I mean, how hard is it to put a PA speaker in front of an amplifier and measure the effects, or lack thereof? 

A long long time ago I owned a Radio Shack phono preamp.  It literally rang like a bell.  Probably due to cheap ceramic caps, but besides that singular piece of gear I've never heard this happen again nor have I seen it demonstrated in solid state gear.  What if, for instance, vibration testing led to better component selection?  Or what if we found out it doesn't matter below 150 dB?  We may never know because  any testing in this field has not become apparent.

Thus far, from the responses here, links provided & other information  I found on the internet, I have found nothing that explains in any logical way why physical vibration affects solid state circuitry. I’m going to ask a few people I know w/ a wealth of many years of high end audio & pro sound experience. I’ll report back if I come up w/ anything worth mentioning. 

Edison got in just at the right time for supplying his High End Audio Replay device.

Mechanised anything was in very little use, so only natural influences to be concerned about.

The Seismographs activity showed substantial changes to their readings during Covid Lock Down Periods, that was the dream period in the last 70 years for the use of Audio Equipment, in relation to ambient energies impacting detrimentally on the end sound.     ,
