3、防磁音箱：
3. Antimagnetic Speaker:
此種音箱可以防止音箱內(nèi)的磁場(chǎng)外瀉，防止對(duì)電視圖像的干擾。
This kind of speaker can prevent the leakage of magnetic field inside the speaker and the interference of TV image.
防磁音箱一般采用雙磁體全對(duì)稱(chēng)屏蔽磁路系統(tǒng)，即在原磁鋼上加裝一塊極 性相反的磁體，并在揚(yáng)聲器磁體周?chē)右粚臃来牌帘舞F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.
鑒別是否防磁，可以將電視置于AV模式藍(lán)背景下，將音箱在電視上面移動(dòng)，觀察電視是否磁化，也可將大頭針?lè)旁趽P(yáng)聲器周?chē)?，?yōu)良的防磁音箱應(yīng)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.
CHP家庭影院的音箱都是防磁音箱，一般在靠近電視時(shí)不會(huì)有影響，但一旦有干擾，請(qǐng)將電視關(guān)閉30分鐘，并使音箱離開(kāi)電視。
