It's the handle of a water kettle. Behind the circuit board is nothing. There is also no other circuit board in the kettle. Is the yellow thing the beeper? Thanks for any help 🙏

Top is a relay, bottom is a capacitor. Thanks! The sound you're hearing is probably from a piezo buzzer like some one else mentioned. I wish I was home so I could send you a picture of one. They can be really loud!

Here's what those buzzers can sometimes look like:

They just make sound to indicate the state of things when used as part of a circuit. Like your kettle being finished boiling water.
