This electro-acoustic transducer contains no electronics making it a versatile component for electronics projects. Apply an AC voltage input to the wires and it will generate sound pressure waves based on the frequency. Connect the wires to a ciruit input and it will generate an AC voltage when stimulated with a sound pressure wave making an efficient knock or vibration sensor.
Supplied in a black plastic casing for easy mounting it can also be deconstructed to suit alternate applications. Without a doubt this is one of our most popular components for a multitude of electronics projects.
