Speakers are usually called speakers, and they are key components that convert electrical energy to sound. In the TV, the sound circuit will be magnified by processing, and the sound will be emitted through the TV speaker. Due to the different occasions and requirements, most of the dynamic speakers are made of internal magnetic types and external magnetic types. The electromagnetic steel magnetic components of the built-in magnetic TV speaker are stronger and the magnetic field is less. The electromagnetic steel of the external electromagnetic speakers is weak and the magnetic field leaks is large.

Due to the limited TV space, various components are very close, especially the visual tube. If it is disturbed by the external magnetic field, it will be magnetized, which will cause the electron beam to deviate from the original trajectory, which will cause distortion and discoloration points to use a built-in magnetic TV speaker.

Therefore, if you use the TV speakers, it is broken and uses the built-in electromagnetic speaker with the same specifications and models. If you cannot buy it temporarily, you can also use an external magnetic speaker, but the speaker should be not far from the visual tube (not less than 15 cm), and the shielding cover should be installed at the same time. This method is to separate the speakers from a tube of about 1 mm thick. But please be careful not to use a ring iron cover, otherwise the TV speaker magnetic field will be short-circuited.
