Piezoelectric buzzers operate on the principle of piezoelectricity, where certain crystalline materials generate electrical charge when mechanical stress is applied, and conversely, undergo physical deformation when electric voltage is applied. In our SMD piezo buzzers, this is achieved through a layered structure consisting of a piezoelectric ceramic disc bonded to a metal diaphragm.
When an alternating current (AC) voltage is applied across the piezoelectric element, the material rapidly expands and contracts, causing the attached metal plate to vibrate. These vibrations transfer to the air as sound waves, creating the audible tone. Since these are passive components (without built-in oscillators), they require an external drive circuit providing square wave signals typically between 2kHz and 5kHz for proper operation.
The frequency of the sound produced depends on the resonant frequency of the piezoelectric element, while the volume (sound pressure level) correlates with the voltage applied and the efficiency of the diaphragm design. This fundamental operating principle makes piezo buzzers notably energy-efficient compared to electromagnetic alternatives, as they consume minimal current while generating substantial sound output.
