There is this buzzer in this UPS (uninterruptible power source) circuit. I want to remove it from this circuit because it make a lot of unnecessary noisy. Black-outs happen too much in my area. Sometimes they happen in the deep night, when I am sleeping, and this little buzzer wakes me up by freaking me up. I always immediately realize it when there is a black-out, so this buzzer is really not needed.
I am not able to de-solder it. Because the PCB is strongly embedded into the case by some very hard clippers. It just won't move.
How do I remove this buzzer from the circuit, or shut it up without removing? I don't plan to re-use it, so it is OK if it is destroyed in the process. I just don't want to get into risk of damaging any other part of the PCB.
Answer
You could quieten the buzzer by filling the hole in the top of the plastic. If you pour in something rubbery (hot glue could be good) then it would almost certainly muffle the sound.
To remove it, I'd crack the plastic with some pliers removing enough to heat the legs with a soldering iron.
