Hi, I have some problem with the microphone of lumia 720, some time it works and some time does not.

If it does not work and i will hit it will my palm, then it starts working, but again stops working after some time.

Many people have been experiencing this same issue after the 8.1 Cyan update. Did you receive this update lately? This is a software issue and I have not seen a proper fix for this at the moment. Although there may be one that I haven't heard of.

If you have not received that update then I would assume that you may have a loose connection. The only way to tell is to open up the phone and check it connections. If the connections look fine then I would think it would be a software problem.
