Piezo buzzer features equivalent

In simplest terms, a Piezo Buzzer is an electronic device that produces a tone, alarm, or sound. Piezo buzzer is like tiny little speakers, but unlike speakers, it does not require an amplifier or other circuit to drive. When voltage is applied to the piezo its size grows and shrinks and tone generates.

How to use a Piezo Buzzer

A beeper is a small yet efficient component to add sound features to our project/system. It is a very small and compact 2-pin structure hence can be easily used on the breadboard, Perf Board, and even on PCBs which makes this a widely used component in most electronic applications.

There are two kinds of buzzers that are generally obtainable. The one shown here is a simple buzzer which when powered will manufacture a Continuous Beeeeeeppp…. sound, the other kind is called a readymade buzzer that will look bigger than this and will manufacture a Beep. Beep. Beep. Sound due to the internal oscillating circuit present inside it. But, the one looked here further widely used since it can be customized with the help of other circuits to fit easily in our application.

grant A simple 9V battery can also be used, but it is recommended to use a regulated +5V or +6V DC supply. It is generally associated with a switching circuit to turn ON or turn OFF the buzzer at the needed time and needs interval

Piezo buzzer Applications:

• Alarming Circuits, where the user has to be alarmed about something
• Portable equipment, due to its compact size
• Automobile electronic
• Communication equipment
