3V 70dB 4kHZ Square Thin SMD Piezo BuzzerThe common small sound signal device uses a piezoelectric buzzer, which mainly depends on the piezoelectric effect to produce vibration and sound. This kind of buzzer is generally divided into two types with or without vibration sources. The direct current signal is used to drive the buzzer with a vibration source, while the AC signal is required to drive the buzzer without a vibration source.
