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 π
Hiding under a hidden and additionally enclosed and secured circuit board, omg cannot believe I didn't break it removing that shit π
There he is! Yup, piezo buzzer, good work op.
No beeper in this photo. Could be a piezoelectric disk hidden some where they are small and thin. whatβs on the other side of the PCB? Also look stuck to the plastic, piezos are often stuck to the casing to use it as a sounding board.
Edit: not sure what the yellow thing, cap maybe, can you get a better picture of the text on it ?
It's an x2 capacitor to supress emi. He eventually linked it to me down below as well.
I believe I see a relay, capacitors, diodes and an inductor. Nothing beepy
Weird huh? Any idea where they hide that fucker, it's loud like a friggin fire alarm π
i would follow the wires until you find either a black plastic cylinder around 5-10mm in diameter with a hole on top, or a brass-colored disc around an inch in diameter. that would most likely be a piezo speaker.
A lot of kettles use sound to indicate state. If you're nervous you should alert your local authorities rather than wait. Better safe than sorry.
Edit: Sorry folks. I thought op meant beeper as in the radio device. It's late where I am and I'm tired, hah. Was just trying to encourage a bit of safety.
Wait what ?
I guess the local authorities really like tea?
Oh lord, I thought op meant beeper as in the radio device. I'm an idiot.
A LOT OF KETTLES USE SOUND TO INDICATE STATE. IF YOU'RE NERVOUS YOU SHOULD ALERT YOUR LOCAL AUTHORITIES RATHER THAN WAIT. BETTER SAFE THAN SORRY.
if i didnt removed it, it would only have been a question of time until someone had to call the cops...
Do beeper services even exist anymore? I would think they all got displaced by cell phones long ago.
I believe they are used in some emergency situations because they use less bandwidth than cellphones and will work when other services wonβt.
?
Is the capacitor an x2 cap for voltage surges? Looks like it. The rest is just normal stuff. Not my field, been out of school for years and am an idiot. That being said I'm curious: what's the inductor by the Emi suppression capacitor for in this circuit? Is it just to form a tank circuit to heat the kettle more efficiently?
cannot say.
idk, not familiar with those things. the kettle can has 5 modes of temperatures: 60β100 Β°C. Its really nice, just insanely loud. More pictures if case it gives more info, sorry for the bad quality, hope its readable
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.
