Hi. todaye while i was playing, i noticed that there is a cylindrical wood in my violin! moving, i am sure it is not entered from outside to my violin,so is there sth that is broken in it?
It might not be a bridge support my guess is it's the sound post.
See the question ' how to put a sound post in to a violin'
fourth question below yours it's likely a specialist job to re-fit as it will be moved around for the best sound.

I think it is a piece that is wedged in underneath the bridge to support it,it is not glued,you will need special pliers to refit it.
