This piezoelectric ceramic wafer plate with a 15 mm diameter is a core sound-producing component used in buzzers, small loudspeakers, and audio alert devices. The piezoelectric ceramic vibrates when an electrical signal is applied, generating audible sound waves. Fitted within an aluminum shell, the wafer is protected and acoustically enhanced by a small resonance chamber created by the housing.

Key Features:

  • Diameter: 15 mm – compact for small transducers and buzzer assemblies.

  • Material: piezoelectric ceramic (such as PZT) with aluminum acoustic housing.

  • Resonant Behavior: typically resonates at a frequency in the kHz range depending on manufacturing and design.

  • Operating Voltage: commonly compatible with low-voltage circuits (e.g., 5–24 V).

How It Works:
When an electrical signal is applied, the piezo element deforms and vibrates, creating sound waves. The aluminum shell enhances sound output and protects the delicate ceramic disc, making it suitable for embedded audio applications.

Advantages:
✔ Easy to use for generating sound in electronics and DIY projects;
✔ Compact and lightweight design for small devices;
✔ Aluminum shell for improved durability and acoustic resonance.

Applications:
✔ Audible buzzers and alarms;
✔ Sound output in toys, appliances, and instruments;
✔ Audio signaling in Arduino/microcontroller projects;
✔ Small speaker and alert circuits.
