Introduction to the principle of professional audio waterproofing

　　1. Cover the outer surface of the box with glass fiber reinforced plastic, wait until the glass fiber reinforced plastic is dry, then polish and spray paint, generally need to spray paint 3-4 times, so that the box body can not only achieve waterproof performance, but also retain the original surface.

　　2. Another more advanced waterproof treatment is to repeatedly paint waterproof plastic glue paint on the plywood of the box body, so that the waterproof paint penetrates into the plywood of the box body, which can increase the sealing performance of the box body, or There is a deeper protection for the box. After the cabinet paint is completely air-dried, polishing and spraying are carried out, and the surface of the original speaker is also preserved. The waterproofing of speakers also has certain technicality. It is not simply to apply some waterproof glue. After ordinary glue is applied, it will affect the damping of the speakers, thereby affecting the sound quality of the speakers. Special glue must be used to evenly distribute the speaker cones and the front panel grille. The outer layer of stainless steel should be covered with several layers of anti-rust paint, and the inner layer of the grille should be covered with a sound-transmitting sponge for treatment to avoid long-term rain, dust, etc. soaking and rotting. Professional waterproof speaker plug accessories are used at the speaker plug and socket.
