This would be caused by emi.
I haven't seen a teardown of the arc so I'm not sure if the speakers are shielded or not. I'm actually surprised it isn't worse considering the form factor.
I only noticed the buzzing when I put my ear right next to the speaker. Headphones don't produce it. It's a non-issue on my end.
