about this item

Make sound waves visible with this awesome device called a vibration speaker. It turns practically any surface into a larger speaker. The audio jack connects to standard audio output sockets. Stick the speaker onto a variety of surfaces and objects to find out which materials produce the best sound. Experiment to see sound waves ripple through a tray of sand or water. With signal generating apps, you can experiment to visualize different sound wave patterns.
Battery: Required, not included
