The FrightProps Transducers are a great way to vibrate floors, walls, benches, and other items. The vibration is controlled by sending audio to the transducer.
HOW DO THEY WORK?
Transducers create vibrating and shaking effects. A speaker contains an electro magnet that moves a cone which displaces air. A transducer is similar but instead of a cone it contains a steel piston that moves and creates vibration. Just like a speaker, a transducer requires an audio source. The lower the frequency the better as this will move the piston the most.
