Abstract:
A coupling device for interposition between an electronic or electro-acoustic component and a supporting structure for the transmission and dissipation of vibratory energy generated within the component while isolating the component from vibratory energy emanating from the support structure, the coupling device comprising:a bearing block having a bearing surface; a spherical ball having a center and engaging the bearing surface for rolling along the bearing surface in response to relative movement between the bearing block and the ball in directions away from and toward an equilibrium position wherein the center of the ball is aligned with the equilibrium position; a ring magnet having a center and located concentric with the center of the ball when the center of the ball is aligned with the equilibrium position; and at least one further magnet juxtaposed with the bearing surface and located relative to the equilibrium position so as to interact with the ring magnet to bias the bearing block and the ball toward alignment of the center of the ball with the equilibrium position.
