You want to hear a very loud noise? Apply 3V to 5V to this buzzer module and you will be rewarded with a 2KHz BEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEP.

Unlike a simple piezo, this buzzer does not need an AC signal. Inside is a piezo plus the driver circuit that makes it oscillate at 2KHz. On the one hand, this makes it an ideal tool for integration into projects, as you do not need an oscillating control signal. However, you cannot change the frequency.
