Piezo Buzzers

Advanced Acoustic Technology Corp. (AATC) piezo buzzers offer a 1mA to 75mA current range, 65dBA to 105dBA sound pressure range, and up to 14,000Hz frequency rating. Piezo buzzers include a piezo plate attached to their plastic housing. When given the input alternating Vpp signal, the piezo plate will vibrate up and down to produce sound. These buzzers are voltage-driven, and their sound output level (SPL) increases positively with voltage. AATC Piezo Buzzers are robust and shock-resistant, making them ideal for harsh environments.
