Is There a Way to Lessen Vibration On Cables From Powered Speakers

I noticed that the interconnects, power and speaker cables that are plugged into the powered speaker have constant vibration.  Is there any way to nullify or reduce that vibration? I was thinking about buying some form of rubber or foam pad and cut out holes for the cables to go. Then place it at the source of connection in an attempt to stop the vibrations from going down the cable.
