Mic arm transferring all noise from desk.

So i recently got a mic arm and it literally transfers anything that i do in my desk into a metal echo sound. For example if i type on my keyboard there will be a metal echo sound of my keyboard. Hopefully some of you guys have experienced this yourself. Does anyone know a work around? I dont have enough space for a one of those big tripod things. And i dont really want to order any anti-vibration pads. If someone could help me out it would be much appreciated :D
