Make sure you don't have any debris in the speaker which could be blocking the sound. That happened to me once and the Apple tech cleaned it right out for me.
Ok,just had to eliminate one possible cause. I Guess,that the damage shown in your picture could have some influence on the loudspeaker function,if the impact was hard enough. Not sure if it can be repaired,the best is possible to contact nearest Apple service centre.
