Low power way to make a sound
Some buzzers work with a DC voltage and some need an alternating voltage.
It sounds like you may need to drive your piezo buzzer with an alternating voltage, not a steady one if you want a continuous …

Buzzer on a computer mainboard
I'm not aware of a "standard" voltage as such, but it's pretty likely to be 3.3V or 5V (possibly 12V). The easiest way would just be to measure the voltage across it when it operates, then select your …
