Abstract
An apparatus and method for dampening vibration of a television tube in a tension mask. The apparatus include a vibration reducing assembly that is affixed between a mask frame and a busbar assembly of a tensioned mask. The vibration reducing assembly is comprised of a tension coil spring with a pin inserted in the center of the coils. As the busbar assembly or mask is vibrated, the spring pulls and releases, allowing the internal pin to rub against the coils, scrubbing away energy. The busbar assembly and the mask are formed such that their independent resonant frequencies differ greatly from one another.
