Thames & Kosmos Geeker Speaker Lab

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, water, and other substances. With signal generating apps, you can experiment to visualize different sound wave patterns.
