Active buzzers and passive buzzers are two essential components used to produce sound in various electronic and electrical appliances. Buzzers are used to raise an alarm, indicate commands, and enhance user interactions. They are used in products like door-entry systems, home appliances, security systems, and many more. In this article, we will discuss the differences between active buzzers and passive buzzers.

Active buzzer is an indicator with driving circuitry built into the device. It has an internal oscillating source, and the buzzer will sound as soon as it is energized. The active buzzer is commonly used in computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers, and a wide range of electronic products.

On the other hand, the passive buzzer does not have an internal oscillating source, and it needs to be driven with a square wave and different frequencies. It operates like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

Passive and active buzzers have different advantages. Passive buzzers are cheaper, and their sound frequency is controllable, allowing for different tone effects. In some cases, a control port can be multiplexed with the LED. Most passive buzzers have a small size and less expensive compared to active buzzers. On the other hand, active buzzers are convenient for program control, and direct DC power drive can sound.

If you are a manufacturer of electronic and electrical appliances, it's important to consider the type of buzzer you need for your products. It is essential to choose the right buzzer for the intended use to ensure optimal performance and reliability.
