Piezoelectric Diaphragms

Same Sky Piezoelectric Diaphragms are ideal for vibration detection and touch feedback applications and offer diameters from 12mm to 35mm. These buzzers feature a compact design with extremely low profiles and a piezo element. The components are available with or without wire leads, both providing easy and reliable design implementation. Same Sky Piezoelectric Diaphragms are externally driven and offer a frequency range from 2.9kHz to 5.4kHz.
