Abstract
Anti-howling device in a cathode ray tube including anti-howling means having contact members each in contact with a shadow mask for receiving, and dispersing a vibration, and connecting members for connecting adjacent contact members, and fixing means for actually bringing the contact members in the anti-howling means into contact with the shadow mask, wherein the contact members receive the vibration of the shadow mask, to disperse the vibration by impact and friction between the contact members and the shadow mask.
Claims32
An anti-howling device in a cathode ray tube having a shadow mask and a mask holding frame, comprising:
- anti-howling means having a plurality of contact members, wherein each contact member is in contact with the shadow mask for receiving and dispersing a vibration, and connecting members for connecting adjacent contact members;
- and
- fixing means configured to bring the contact members into contact with the shadow mask, such that the contact members receive the vibration of the shadow mask and disperse the vibration by impact and friction between the contact members and the shadow mask.
A vibration damper for use in a cathode ray tube having a shadow mask, comprising:
- a plurality of contact members in contact with a shadow mask and adapted to receive and disperse a vibration;
- a plurality of connecting members, each connecting member disposed between adjacent contact members and adapted to connect the adjacent contact members;
- and
- a holding member connected to at least one of the plurality of contact members and adapted to hold the plurality of contact members in contact with the shadow mask.
A vibration damper for use in a cathode ray tube having a shadow mask, comprising:
- a plurality of contact members in contact with a shadow mask and adapted to receive and disperse a vibration, wherein a shape of each of the plurality of contact members is one of spherical, cylindrical, hexahedral, and ring;
- and
- a plurality of connecting members, each connecting member disposed between adjacent contact members and adapted to connect the adjacent contact members.
A vibration damper for use in a cathode ray tube having a shadow mask, comprising:
- a plurality of contact members in contact with a shadow mask and adapted to receive and disperse a vibration, wherein at least one of the plurality of contact members is hollow;
- and
- a plurality of connecting members, each connecting member disposed between adjacent contact members and adapted to connect the adjacent contact members.
