Can overheating cause speaker distortion?

While using my iPhone to post a comment on a tech site, I noticed it getting warmer than usual (mine always seems to get warm when I use it for greater than 10 minutes). As a result, I put the phone to sleep and was greeted with this noise after the familiar click:

At first, I thought my iPhone was going to explode, but after a little experimenting, I concluded that it was a speaker issue. The sound was not reproducible when the phone was muted, but when the sound was on, I kept getting this noise every time I locked the phone. A simple reboot has seemingly fixed the issue. Any ideas on what might have caused this? Should I get the phone checked out, or do you think this noise was just a fluke?

I encountered the same thing - did a full restore on the phone and it appears to have cured the issue. Sounded just like your YT vid and to my ears, it comes across like the "lock click" is looping then fading out. Software glitch? I hope so as there are plenty of other issues with the new iPh4.

Thanks for the reply. At least it is comforting to know that I am not the only one that has experienced this. May I ask what you were doing with your phone when you first noticed this?

What other issues have you been having with your phone? For me, it has mainly been battery life and heat issues. Standby time with location and push services off is spectacular, but as soon as I start using the phone, I start losing battery life fast. I've also noticed that my iPhone gets noticeably warm whenever I use it for more than 10 minutes. Is it normal for the iPhone to get warm when playing music with the screen off? It just seems like the A4 generates a ridiculous amount of heat performing even the simplest of tasks. Hopefully none of this is as big a deal as I make it out to be.
