Buzzers

Piezo Buzzer vs Piezo Transducer
A Piezo Buzzer will output a continuous tone when the rated DC voltage is applied to its terminals. The Piezo Buzzer contains an internal oscillator to produce a typical 1-2 KHz tone. A Piezo Transducer is really a speaker that requires an audio oscillating tone be applied to its terminals to produce a sound. No sound will be produced when a DC voltage is applied.

BUZ-12054P Passive Piezoelectric Buzzer 44x14mm , with Wires
US$1.36
This is nicely enclosed with wiring so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts and you can use it as a sensor, to detect fast movements like knocks. Unlike the active buzzer that only requires a constant voltage this passive buzzer will need a microcontroller to help it run. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

AM-121AS Active Buzzer Module
US$1.99
The active buzzer has a shock source inside, so it will be called as long as it is electrified. Program control is convenient. Buzzer Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is 5V DC Electronic Part Active Buzzer Module. Using top quality material, it is durable in use. What is more, an active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

AM-121 Active Buzzer Module
US$1.99

The KY-012 active piezo buzzer is a 3-pin module that creates an audible sound at 2.5 kHz without the need for pulse width modulation (PWM) or any additional complex code. The only requirement is to set the signal pin to HIGH.  If you’re looking for a simple but effective way to build audio into an Electronics or Arduino project, the KY-012 Active Buzzer Module is a great choice, and is designed to simply produce a single-tone sound when the incoming signal is high. This allows for single-pin operation on an Arduino Board, which is perfect for building a custom alarm or detection system that can send out an audible signal when it receives the electronic high signal from the Arduino controller board.
