Industry Information July 25, 2018 - How do piezoelectric buzzers work?
A piezo buzzer is a sound producing device.The main working principle is based on the theory that, whenever an electric potential is applied across a piezoelectric material, a pressure variation is generated. A piezo buzzerconsists of piezo crystals in between two conductors.When a potential differe
Industry Information July 17, 2018 - What is the 1/2 duty square wave?
If the user uses a passive piezoelectric buzzer or a passive electromagnetic buzzer, it is recommended to use 1/2 square wave in the input voltage and frequency conditions. Why use it? Because this condition can The buzzer (buzzer) inside the buzzer achieves the highest amplitude, which means that t
