The Mini Active Buzzer 5V-12V stands out as a compact yet robust audio solution for electronic applications. Designed to operate within a 5V to 12V range, it produces a sharp 85dB sound at 10cm, making it perfect for notifications or alerts. Unlike passive buzzers, this active model features an internal oscillator, generating a steady 2300 ± 300Hz tone with just a DC power supply—no complex signals required. Its small size, typically around 12mm in diameter and 9.5mm in height, fits snugly into space-constrained projects, from DIY gadgets to industrial systems.
