35mm Passive Piezo Buzzer Ceramic Disc (2 Wire Piezoelectric Sounder, 1 Qty)

The 35mm Passive Piezo Buzzer is a large diameter piezoelectric sounder designed for audio indication, alarm systems, vibration sensing and electronic notification circuits. Featuring a 35mm diameter ceramic piezoelectric element bonded to a brass metal disc, this passive buzzer produces sound when driven by an external alternating electrical signal. Its larger surface area makes it suitable for applications requiring effective sound generation and vibration detection.

The 35mm piezoelectric buzzer operates using the piezoelectric effect, where an applied alternating voltage causes the ceramic element to vibrate and generate sound. Unlike an active buzzer, this passive piezo sounder requires an external oscillator or microcontroller generated signal to produce an audible tone. The element can also generate an electrical signal when subjected to mechanical vibration, making it suitable for knock detection, impact sensing and musical pickup applications.
