Piezo Buzzer Element with Aluminum Cover
These piezo buzzer elements combine a ceramic piezoelectric disc with a rigid aluminum cover to create a low‑profile acoustic transducer optimized for panel mounting and embedded designs. The aluminum shell protects the ceramic plate while helping to form a small resonance chamber that improves sound output and durability in compact devices.
Features:
- Durable aluminum cover for enhanced protection and acoustic efficiency.
- Pre-wired with red (positive) and black (ground) leads for simple connection.
- Low power consumption, ideal for battery-powered devices.
- High reliability with no mechanical contacts, ensuring noiseless operation.
