35mm Silver Piezo Disc

The 35mm Silver Piezo Disc is a piezoelectric electronic component designed for sound generation, vibration detection, and sensing applications. It operates using the piezoelectric effect, a property of certain ceramic materials that allows them to convert electrical energy into mechanical vibrations and mechanical pressure into electrical signals. This dual functionality makes the piezo disc suitable for use as both a sound-producing element and a vibration sensor in a wide variety of electronic circuits.

The disc consists of a piezoelectric ceramic layer permanently bonded to a thin metal plate, forming a compact and lightweight structure with a diameter of 35mm. When an alternating electrical signal is applied across the piezoelectric material, the ceramic expands and contracts rapidly, causing the metal disc to vibrate and produce sound. Conversely, when the disc is subjected to physical pressure, vibration, or impact, it generates a small electrical voltage that can be detected by electronic circuits.

The 35mm Silver Piezo Disc is widely used in piezo buzzers, electronic alarms, knock sensors, vibration detectors, musical instruments, and embedded electronics projects. Due to its low power consumption, high sensitivity, and reliable performance, it is a popular choice for Arduino, Raspberry Pi, and other microcontroller-based systems.

Its solderable contact points allow easy integration into custom electronic circuits, while its compact design makes it suitable for space-limited applications. The piezo disc provides long operational life because it contains no moving mechanical parts that wear out during normal use.

Working Principle

The 35mm piezo disc works using the piezoelectric effect:

• When an AC electrical signal is applied, the ceramic layer expands and contracts.

• The attached metal plate vibrates along with the ceramic layer.

• These vibrations produce audible sound waves.

• When mechanical pressure or vibration is applied to the disc, the ceramic material generates a small electrical voltage.

• The generated voltage can be measured by electronic circuits for sensing and detection purposes.
