The EasyBuzz Board is an accessory board featuring a piezo buzzer capable of emitting audio signals. It is required to generate a voltage signal of specified frequency in order to operate the piezo buzzer normally. The on-board piezo speaker is capable of playing sound frequencies in the range between 20 Hz and 20 kHz. However, the resonant frequency of piezo speaker is 3.8 kHz and the best sound quality is achieved using frequencies between 2 kHz and 4 kHz. A DIP switch further aids in configuring board connections. The buzzer driver can be provided with a digital signal or a pulse-width modulated signal, where sound pitch is regulated by the PWM frequency, and sound volume can be adjusted by changing the PWM duty cycle. It has a female IDC10 connector. The EasyBuzz Board supports both 3.3V and 5V systems.
With such features, the Piezo Speaker add-on board is an ideal choice for adding audio signalization to any prototype device.

Based on the inverse principle of piezo electricity, the lightweight and affordable piezo speaker is designed to emit audio signals and produce sound. The piezoelectric element is driven by an oscillating electronic circuit or other audio signal source driven with a piezoelectric audio amplifier. These are frequently used as buzzers and beepers in alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.
