As we all know, soon after the speaker metal is exposed to the air, the surface will be oxidized, lose luster, and become dull. Even if the surface of the signal wire plug is gold-plated, it is not easy to oxidize, and there is close contact with the fuselage plug, but for a long time, there will still be a certain degree of oxidation leading to poor contact, so it is necessary to clean once every six months. As long as you smear the contact with cotton and alcohol, after this heavy work, you can make the contact return to contact, and the sound will be clear and transparent.
