There is a UK manufacturer who demonstrates the vibration transmission of cables. The test consists of knocking one end of the cable, say a spade lug, and listening to the impulse at the other end with a stethoscope. I think the manufacturer is Vertex AQ. They demonstrate the abilities of their cable which includes a box of vibration damping or absorbing materials to reduce this effect. Now consider if one end of a speaker cable is attached to a vibrating speaker...

Now given that an electrical field will induce a charge in a conductor which cuts across it, say the metal chassis of a power amp,or internal hookup wire, and the potential for vibration to modulate this, it is possible to theorise on how vibration affects sound, quite apart from any microphonic components being excited.
