I recently dropped my scanner from around 3 feet, it did not even get a scratch. Too bad this was the 2nd time in 3 years. Every so often there is a strange rattle or vibration in the speaker. If I had to describe it I would say it sounds as if the scanner was lying on its back with a grain of salt on the speaker, bouncing around. The sound has a small distortion. Then again it reminds me of a cracked speaker or one with a tiny tear. Is it common for these speakers to go bad after a couple of years?
