How do certain regular objects play audio with no speakers if a radio transmission is powerful enough?

Question

I saw a TIL post talking about a radio station that transmitted so much power that people nearby could hear it in their furniture. How is that even possible? I though speakers were made to that audio could be correctly relayed yet a spring mattress can play audio?

I was wearing a large belt buckle and someone asked me if I got good reception. Lol. No, but I guess it’s possible.
