First find your horn, or buzzer. Figure out the power requirements of the buzzer. Find a battery or DC supply that meets the buzzer's requirements. Wire from (+) terminal of battery to one terminal of a switch. The other terminal of the switch, wire to the (+) terminal of your buzzer. The (-) terminal of your buzzer, wire to the (-) terminal of you battery.

Push the button, and hear the buzzer.
