Abstract
A very thin, self-contained, portable, vibrating platform having three major elements: 1) a platform structure constructed from thin (e.g., one half inch) plywood, particle board, or other suitable material, such that when assembled its top and bottom surfaces are completely smooth and all other components are contained and environmentally sealed within the envelope of the platform; 2) a very thin (e.g., 0.4 inches) electromagnet designed to be connected to a source of alternating current; 3) a ferrous metal rod mounted in close proximity to the magnet such that the rod will be attracted to the magnet when current is applied. The rod is attached to the platform in a manner such that it will preferably physically resonate at, or near, the same frequency as the applied alternating current and thereby amplify and induce kinetic forces into the platform structure causing the entire platform to vibrate.
