Why mini motherboard speaker has 4 pins although there are just 2 wires goes up to the buzzer?
This is actually a good question. However, what you see is actually a piezo speaker, not a buzzer. While speakers only require two wires, most motherboards have four pins where the speaker header plugs. Usually, the extra wires are an extra ground and perhaps 4.5 volts, if not 12 volts. It is possible that the extra pins were intended for the front panel lights.
Or, it is possible that manufacturers once left open the possibility of adding an audio amplifier. You have everything you need there for an amplifier. You have positive and negative signal wires as well as positive and negative direct current.
