Definitions for "Magnetic Shielding"
Lead plates are placed in the walls of home cinema loudspeakers to prevent the magnets within the speaker drivers from damaging a nearby television screen. Essential for centre speakers that are usually placed very close to the screen. Not required for projection systems.
A design of loudspeaker motor in which the stray magnetic field is suppressed to avoid distortions to CRT, or other magnetically sensitive, video displays.
Magnetically shielded speakers are important in Home Theater applications because of the damage the magnetic field of a speaker can do to a television set. This feature is critical for the centre channel and front left/right speakers.
Enclosure of electronic components to prevent electromagnetic interference or emanation.
When magnetic fields, electromagnetic or radio frequency interference are deterred and safeguarded from structure.
