The datasheet for the buzzer is here: cui.com/product/resource/cmt-4023s-smt.pdf In terms of the coin cell battery, any will sort of do. Preferably a Zn-Air battery, but I understand they operate at a lower voltage than say the CR2032 | |
| Aug 21, 2017 at 22:07 | comment | added | Vince Patron | Can you use more than one coin cell battery? Can you post exact parts and links to datasheets? What voltage can the buzzer operate at? Can't really attempt a good answer without more specific numbers. Take at the "Pulse Discharge Characteristics" of a CR2032 to get a better idea: data.energizer.com/pdfs/cr2032.pdf | |

| Aug 21, 2017 at 21:00 | comment | added | Marcus Müller | anyway, @Transistor is right: without knowing the voltages of your coin cell, the behaviour of your buzzer, and the specifics of when, how early, and how long you want to buzz, no chance to do anything but guess. | |
| Aug 21, 2017 at 20:59 | comment | added | Marcus Müller | well, you might be able to (slowly) charge a large capacitor with your coin cell and then use that to actuate your buzzer, buuuut: Sounds like a really bad idea. That coin cell is going to be empty, either by plain usage, or by leakage currents of that capacitor in no time. Plus that capacitor is large. In essence: you're using the wrong tools for your job. | |
| Aug 21, 2017 at 20:58 | comment | added | Transistor | Add a link to the datasheet for the SMD buzzer othewise we're guessing. | |
