Arduino Passive Buzzer Speaker Mini Piezo Module

Add Sound & Tone to Your Arduino Projects

The Passive Piezo Buzzer Module is a small, versatile sound component that lets your Arduino or microcontroller generate tones, melodies, alarms, and sound effects. Unlike active buzzers, the passive piezo requires a PWM signal to produce sound — giving you full control over frequency and pitch to play custom tunes.

Key Specifications

• Type: Passive Piezo Buzzer (requires PWM/AC drive signal)
• Operating Voltage: 3.3V – 5V DC
• Frequency Range: 1Hz – 20kHz (audible range: 2kHz – 5kHz optimal)
• Interface: 2-pin or 3-pin module (VCC, GND, Signal)
• Low current consumption
• Compact mini form factor — fits easily on breadboard
• Compatible with Arduino tone() function

Passive vs Active Buzzer

• Passive (this product): Requires PWM signal; can play melodies and variable frequencies
• Active: Produces fixed tone with DC power only

Common Applications

• Alarm and alert systems
• Musical tone and melody generation
• Button click feedback sounds
• Game sound effects
• Notification beeps in IoT devices

Package Includes

• 1 × Passive Piezo Buzzer Module

Use Arduino’s built-in tone() function or the Pitches library to play songs like Happy Birthday, Star Wars, and more — right from your sketch!
