Passive Buzzer

A passive buzzer is an electromechanical sound transducer that requires an external AC signal or PWM waveform to generate sound. Unlike active buzzers, it cannot produce sound with a constant DC voltage, making it ideal for creating melodies and variable frequency tones. This module is widely used in Arduino projects, alarms, timers, and interactive electronic devices. Key features include a compact design, easy PCB mounting, and a wide operating voltage range. It is cost-effective and perfect for hobbyists, students, and engineers looking to add audio feedback to their circuits. Choose this buzzer for its versatility in generating different tones and its compatibility with popular microcontroller platforms.
