External-Driven Piezo Transducer

This type consists of a piezo disc and resonant chamber. It requires an external driving circuit to operate. Sound characteristics (tone and volume) are controlled by adjusting the frequency, voltage, and waveform of the signal input. It offers high reliability and fast response, making it ideal for electronic device alerts, security alarms, and medical instruments.
