It’s not as common now, but lots of desktop computers used to have little piezoelectric speakers that would beep to indicate error codes or catastrophic failure.
They’re called speakers but they’re only good for buzzing at different frequencies instead of accurately replicating source audio. Interestingly, the more advanced ones can be used quite effectively to make ultrasound signals.
Only because the average user would have no clue how to find and disconnect the piezo speaker, assuming they even know about it. And, of course, it’s a lot more distracting than sound coming though someone headphones or whatnot.
Perhaps the piezo speaker can still be used to mess with people.
What do you mean?

Well I knew about that, but how does it mess with people any better than the default audio sink?
