My earpiece is not working

Last night I had something in my earpiece speaker grill. After i wiped it out, i noticed that it looked different, as if the whole grill moved slightly. When I started listing to a video, i noticed that the earpiece was pretty much busted. There was a slight sound but as a raised the volume, the bottom firing speaker kept getting louder while the earpiece was just quite and muffled. I know its not software because i have done everything to troubleshoot. Is there a way I can go into apple and get that earpiece repaired? I was looking somewhere online but there is no where to go to find out if apple can or any type of price.
