The importance of internal magnetic loudspeaker to TV set

The speaker, the speaker, is a key device for converting sound into sound. In television, audio amplification circuit through the processing, and finally through the speaker sound. Due to the applications and requirements of different, loudspeakers made many inner magnet and the outer magnetic type two. Internal magnetic loudspeaker magnet magnetic leakage magnetic field is strong, small. The magnet magnetic weak while the loudspeaker, leakage of high magnetic field.
Because of the limited space in the TV, all kinds of components are close to each other, especially in the picture tube, if the interference of the external magnetic field will be magnetized, so that the electron beam away from the original trajectory, distortion and splash, and therefore more than the use of the TV inside magnetic speakers.
So, if you use the TV speaker is bad, it is best to use the same specification model of the internal magnetic speakers. If you can not buy, but also with external magnetic speakers, but should be far from the picture tube (not less than 15 cm), at the same time, the installation of shielding. The method is separated by a plate between the loudspeaker and the tube, the thickness of about 1 mm. But note that the ring can not be used to cover, otherwise the speaker will be short magnetic field.
