speaker damage from compressed air?

[Alex_Perry]

in an attempt to blow out some dust from behind the camera glass of my n8, i blew some air through the speaker slot next to the camera. It didn't blow out the dust, so i removed the top and bottom caps of the phone along with the battery.I gave up taking any more apart and put it all bac together since i still wasn't going to expose the back of the camera glass. Now, i have a distorted sound from the loudspeaker. Could the speaker be damaged from the air compressor, or did i just coincidentally knock around some more dust on the speaker? If it's damaged, i'll replace the speaker with one from my old, dead n95 as long as Google hasn't failed me in finding a bunch of sites that give the same part number for both phones.Worst part of all this, the camera is still dusty.

It's possible the speaker is damaged. Depends on the force of the air and how fragile the little speaker is. Those "air duster" compressed gas cans you buy can blow quite hard. I've seen other products damaged by the force of the gas blast.

Way back in the film camera days I worked at the photo equipment dealer and I saw lots of cameras with the shutters blown out, and even one with the reflex mirror cracked. All thanks to miss-use of compressed air dusters.

I also know someone who blew out the membrane of a ribbon tweeter in an expensive speaker.
