Passive 16 Ohm Buzzer Speaker – Pack of 2

Description:

This Passive 16 Ohm Buzzer Speaker is a miniature sound transducer ideal for generating custom tones, beeps, and audio feedback in embedded and hobbyist projects. Unlike active buzzers, this unit requires an external drive signal—such as a square wave from a microcontroller or tone generator—to produce sound, offering greater flexibility in pitch and sound control.

With a compact and lightweight design, the buzzer features 2-pin through-hole mounting for stable placement on PCBs. Rated at 16 ohms, it can be safely driven by typical GPIO pins through a transistor or audio amplifier circuit. Supplied in a pack of 2, these buzzers are perfect for educational kits, sound-generating projects, and DIY electronics.
