BUZZER, HOOTER & SIREN
A Piezo Ceramic Buzzer consists of an acoustic case precisely engineered to resonate at the specified frequency range. The piezo crystal is attached to a Metallic Vibrator, on application of AC/DC voltage it vibrates at the same frequency as the applied AC/DC signal. Resonation of the vibration in the cavity produce sound.
