BOARD BALANCING INVOLVES HORIZONTAL PLANE MOVEMENT IN ALL DIRECTIONS

The Balancing Board System
The audio stand structure incorporates a new proprietary Rogoz Audio antivibration system, BBS (Balancing Board System, Patent P.404137). The system consists of a threaded, height-adjustable spike made of high-fiber-content steel alloy, on top of which two elements are placed, each with an inner bearing. An intermediary (middle) element is made of carbon fiber and supports another element, a steel bearing inserted into the shelf. Point contact between the steel spike and the carbon intermediary element prevents movement of either element relative to its axis, but it allows pendular motion. Meanwhile, the contact between the intermediary element and the bearing inserted into the shelf allows restricted rolling motion and sliding motion. Consequently, the advantages of spike point support (contact area has been minimized and kinetic energy turns into heat) have been combined with the effects of deadening vibrations owing to to sliding friction and rolling resistance.
