What Are Piezo Buzzers?
A piezo buzzer is an electroacoustic device that converts electrical energy into sound using piezoelectric elements. Known for their compact size and efficiency, piezo buzzers deliver clear, consistent tones while consuming minimal power. They are widely used in industrial machinery, medical equipment, automotive electronics, and security systems to provide audible alerts and status indicators.What Are Audio Indicators?
Audio indicators, also referred to as sounders or signal buzzers, are essential in applications where an audible warning is required to supplement visual cues. These devices can be continuous tone buzzers, intermittent alarms, or programmable sound indicators. They are available in enclosed housings for standalone use or as board-mount sound devices for integration into control panels and electronic assemblies.Key Benefits of Our Piezo Buzzers and Audio Indicators
- Low power consumption for energy-efficient designs
- High sound output for audibility in noisy environments
