The working principle of the SMD buzzer passive:
The working principle of the SMD buzzer passive is based on electromagnetic induction. When current passes through the electromagnetic coil inside the buzzer, it generates a magnetic field. This magnetic field interacts with the permanent magnet inside the buzzer, causing the diaphragm (usually a thin metal piece) to vibrate. The vibration of the diaphragm pushes the surrounding air, producing sound.
This type of buzzer typically requires an external AC signal source to drive it because there is no oscillator circuit inside the passive buzzer. When the frequency of the supplied AC signal matches the natural frequency of the diaphragm, the diaphragm vibrates with maximum amplitude, producing the loudest sound.
