It depends on the kind of 'buzzer' it is, there are many different types, some are polarity sensitive and some are not.

All buzzers with internal oscillators have polarity because they have small circuit built into them while the buzzers with only Piezo disks can be operated both ways.

That's why most buzzer's/beepers have color coded wires (Red And Black)
