Is it possible for laptop speakers (versus external speakers or headphones) to pick up radio signals?

Heard a strange sound a couple of times last week while web browsing. It sounded very much like I was listening to someone’s microphone (e.g. the sound was static-y, it sounded like papers were rustling and then music was playing, etc.) but the sound ended abruptly, without me touching anything. I couldn’t investigate it before it ended, and I couldn’t see anything in any of my tabs that indicated something had played. It also definitely did not sound like an ad….

Researching the problem a bit, I’ve seen something similar reported relatively frequently, with the explanation being that the person’s speakers or headphones had picked up some AM radio signals, a baby monitor, etc. The small catch is that I only ever saw external speakers or headphones being discussed, rather than laptop speakers. My question, then, is whether the speakers being a laptop’s internal speakers would make a significant difference, e.g. due to being more “insulated”.

I’d very much like to chalk up what I experienced to an explainable physical phenomenon rather than, for example, a trojan that has evaded all of my anti-malware scans somehow. Figured that here seemed like an appropriate place to ask, though if I’ve misjudged this and another place would be better, I’d be happy for suggestions.
