How to Make a Loud Electric Buzzer

One can use a loud electric buzzer as an alarm, a doorbell for a child's bedroom, or even as a little prank on friends or family. No matter how you plan to use your electric buzzer, though, it can be assembled for little money and in just a few minutes. Here is a step-by-step guide on how to do so.

Things You'll Need

• 5v Piezo electric buzzer
• 3v Cell battery
• Scotch tape
• Scissors
• Wire snips

Instructions

Making a Loud Electric Buzzer

1. Remove the shrink wrap from your buzzer.

2. Snip the wires from your buzzer with wire snips about an inch outside the base of the buzzer. You don't need all that extra length in wire since your battery will be right on top of your buzzer.

3. Set the buzzer upside down.

4. Place your battery on your buzzer between where the wires used to be. Squeeze it until it buzzes. If it doesn't buzz, then flip the battery the other way and try again. The positive and negative ends of the battery must line up with the positive and negative sides of the buzzer.

5. Wrap the whole assembly in Scotch tape, but just enough to hold it together.
