BPC2310 23MM 3~24V DC Internal Driven Constant Loud Sound Piezoelectric Buzzer High Temperature Resistant Plastic Housing Buzzer

Piezoelectric buzzers are electro-acoustic components that generate sound using a piezoelectric ceramic element. When an electrical signal is applied, the ceramic material rapidly deforms, causing a diaphragm to vibrate and produce audible sound. They are known for very low power consumption, fast response, and high efficiency. Piezo buzzers can operate over a wide frequency range and support various sound patterns when driven by external signals. With their compact size, lightweight structure, and long lifespan, they are widely used in consumer electronics, alarms, medical devices, and portable equipment for alerts and notifications.

Product Advantage

1. Ultra-Low Power Consumption & High Energy Efficiency

Piezoelectric buzzers consume very low current, typically less than 10mA, making them ideal for battery-powered and portable devices. By directly converting electrical energy into mechanical vibration through piezoelectric ceramics, they minimize energy loss and improve efficiency. This allows longer device operation time and reduced energy costs, especially in IoT and wearable applications.

Product Operate Guide

When selecting a piezoelectric buzzer, first determine whether a self-drive or external-drive type fits your circuit design. Check the rated voltage and ensure compatibility with your system. Evaluate the sound pressure level (typically 80–100dB) based on your application environment. Consider the frequency range for desired tone clarity, and confirm size and mounting type match your PCB layout. Reviewing operating temperature and reliability standards will further ensure stable performance and improved user experience.
