The Beginner's Guide to Piezoelectric Buzzers: Selection, Applications, and More
Piezoelectric buzzers are versatile and widely used components in electronic devices for generating sound. Whether you're a hobbyist or a professional, understanding how to select and use these buzzers can significantly enhance your projects. This beginner's guide will walk you through the essentials of piezoelectric buzzers, including their selection, applications, and more. What are Piezoelectric Buzzers? The piezoelectric effect, which occurs when some materials produce an electric charge in reaction to mechanical stress, is the basis for how piezoelectric buzzers work. Usually, a piezoelectric ceramic disc is attached to a metal plate to create these buzzers. The disc makes a sound when an alternating voltage is applied because it vibrates. How to Select a Piezoelectric Buzzer 1. Voltage and Current Requirements : Ensure the buzzer's voltage and current specifications match your circuit. Most piezo buzzers operate at low voltages, typically between 3V and 12V. 2. S...
