I think the eMachines eOne (that iMac G3 knockoff) playing a weird buzz sound when Windows is running might also be related to poor shielding, but I could be wrong about this.
The electronics in the speaker’s internal amplifier resonating to a frequency of old 2G GSM signals and then amplifying that interference. It happened with cheap speakers because as the other person pointed out, they were poorly-shielded, if at all.
How did this work
Poor shielding. So when a nearby phone sent out radio bursts to reach say the cell tower, it would case the speakers to pick up the bursts.
Speakers manufacturers now know wireless devices will be all around their devices, so they shield them better.
