3、防磁音箱：
3. Antimagnetic Speaker:
此种音箱可以防止音箱内的磁场外泻，防止对电视图像的干扰。
This kind of speaker can prevent the leakage of magnetic field inside the speaker and the interference of TV image.
防磁音箱一般采用双磁体全对称屏蔽磁路系统，即在原磁钢上加装一块极 性相反的磁体，并在扬声器磁体周围加一层防磁屏蔽铁罩。
The diamagnetic speaker generally adopts the double magnet full symmetrical shielding magnetic circuit system, that is, a magnet with opposite polarity is added to the original magnetic steel, and a layer of diamagnetic shielding iron cover is added around the magnet of the loudspeaker.
鉴别是否防磁，可以将电视置于础痴模式蓝背景下，将音箱在电视上面移动，观察电视是否磁化，也可将大头针放在扬声器周围，优良的防磁音箱应不吸。
To identify whether it is antimagnetic, you can put the TV in the AV mode blue background, move the speaker on the TV to observe whether the TV is magnetized, or put the pin around the speaker. Excellent antimagnetic speakers should not absorb.
颁贬笔家庭影院的音箱都是防磁音箱，一般在靠近电视时不会有影响，但一旦有干扰，请将电视关闭30分钟，并使音箱离开电视。
