Device and method for reducing a vibration of a board, in particular a transparent board

摘要

The method involves recording measuring data from an edge area (4) of a vibrating plate (2). The plate is loaded over the edge area with the compensation vibration depending upon the measuring data. The measuring data records parameters for each quadrant (15,16,17,18) of the plate at points of the edge area of maximum curvature of vibration modes of the plate through a linear combination to suitable measuring data. Independent claims are included for the following: (1) a device for reducing vibration of a transparent plate, particularly a disk used in a window; and (2) a modal space control unit for vibration reducing device.
