You would think that cinema speakers
... would be impervious to damage but some movies occasionally overdrive the speakers to a point that the drivers are damaged. ... there was 7 seconds of high pitched buzzing on reel 4 that could destroy the speakers.
A big difference is that those are speakers with separate woofers and tweeters. A typical audio signal has the vast majority of the acoustic signal in the low frequencies, so a loudspeaker capable of handling 100 W could have 90 W for the woofer and 10 W for the tweeter. If you send a maximum-amplitude high-pitched sound to the speaker, it will fry the voice coils in the tweeters. (I've had this happen when I tried to check whether I could hear up to 20 kHz from my loudspeakers
One could wonder why tweeters are not fused, though. Apparently this is not trivial.
Anyway, laptop speakers are most likely a single driver for the whole frequency range, so tweeter overloading is not an issue.
