I wouldn't call it a "bug", more "unfortunate physics". Still possible to guard against that, specifically. (There will always be more "unfortunate physics", for example I bet that the hard disk also fails if I smash it against a wall at 100mph, but nobody's going do care designing a consumer HD that stops exhibiting that specific behavior.)

I'm not sure that the definition of "bug" is so narrow as to exclude unfortunate physics, given that it began as literal bugs before becoming metaphorical bugs. Erroneous human influences on software seems slightly farther from the original than peculiar physical influences on hardware!

There's more physics issues with the speakers themselves; especially for something like a laptop speaker in a small enclosed space, it's totally possible to blow it out by turning the volume up too high.

There are various ways to protect against this, easiest being to just limit the top volume. If this is done in the official audio drivers then watch out if you decide to install Linux.
