  • Only one variant has buzzer that is actually audible from a distance

    Do you know if there's a reliable way to get that one with louder buzzer? What kind of sounds can it produce? Could I connect it to my Bangle to have it act as a small speaker?

    No, I don't even know which seller it was and even then the stock could change. But I bought 10 pieces of bigger "7525 Passive" one from https://www.aliexpress.com/item/32864653388.html and desoldered the small one and wanted to solder some thin wires to it put it to some space inside (it does not fit on the PCB and the case is too thin there anyway), I verified it fits in one place in the center where the thin hole is but did not actually finish it. With the slightly bigger one with rechargeable battery it could be done too there is even more space inside but maybe desoldering the buzzer on that one may be more complicated without hot air. However the rechargeable battery could last longer with the buzzer than CR2032.
