Blown Speaker?
 
I just recently bought myself a brand spanky new Toshiba laptop, and proceeded to install the latest version of Ubuntu since I've been out of the computer scene for a little while. I'm impressed, it picked up everything right off the bat, including my wireless card, even though it's not showing up, it's closer than any linux distro has ever gotten. ANYWAY, I just got orders to Fort Lewis, WA, and I was to drive. So I packed up my ACUs and put my laptop in the passenger side floorboard of my car and took off. My laptop operated fine before the trip. Upon stopping at the end of my first day of driving I pulled my laptop out to listen to some good old Ozzy, and the left speaker made a loud squealing noise. The computer operates fine, and sound comes from the right speaker just fine. However the left speaker squeals really loud, and if I try to adjust the volume at all, I lose all sound until I restart the computer. Can anybody help me out with this issue? I was thinking maybe a blown speaker since it was sitting next to the speaker in the passenger side door, and I turn the music up pretty loud while I'm driving. Could the vibrations of the car speaker have blown the speaker in my laptop next to it?

I dunno about the effects of vibrations, but in the past I have managed to damage electronic circuitry by placing it too close to a speaker. I think the magnetism is more dangerous, especially with bigger speakers.

Check your ALSA settings.
Code:

alsamixer
In particular, when my PCM setting was set too high, I got this horrible shrieking type of noise from the speakers. Turning it down solved the problem.

With regards to your question, No, it seems highly unlikely that just having the laptop in your car while you're driving and cranking the tunes would damage it.

Turn off any microphones. Try update ALSA.

Small speakers are more prone to failure if bass frequencies are feed into them. Also amplifying or equalizing will make them go out sooner.

Placing a very high strength magnet near solid-state electronics will not ruin them.
