摘要
A structure for damping vibration of a shadow mask fitted to a mask supporting body in a flat cathode ray tube is provided. The structure includes a plurality of damper wires each fastened under tension to the mask supporting body for strapping the shadow mask between beam pass through holes in the shadow mask. The damper wires and the shadow mask are configured such that a first order natural frequency of vibration of the damper wire falls outside a range within ±10% of a third order natural frequency of vibration of the shadow mask. The structure improves vibration damping, reduces the number of required components and simplifies the fabrication process.
