Waterproof magnetic shielding outer cover for sound box

Abstract

The invention discloses a waterproof magnetic shielding outer cover for a sound box. The waterproof magnetic shielding outer cover comprises a cylindrical shell, wherein an inner liner is set on the inner side face of the cylindrical shell; a supporting device is set at the lower end of the interior of the cylindrical shell; a metal cover is set at the upper end of the cylindrical shell; through holes are set on the upper surface of the metal cover; an inner liner structure is set in the metal cover; threads are set at the upper end of the side face of the cylindrical shell and the lower end of the inner side face of the metal cover; the cylindrical shell and the metal cover are in threaded connection; a rubber ring is set at the upper end of the inner side face of the metal cover; an annular plate is set at the upper side of the outer side face of the cylindrical shell; and a sealing ring is set on the upper surface of the annular plate. The waterproof magnetic shielding outer cover for the sound box is simple in structure and good in sealing and is dismountable. The sound box can be stored. Dustproof and waterproof effects can be achieved. A magnetic shielding effect also can berealized. The sound box can be protected. The sound box is prevented from being damaged. The use is convenient.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a waterproof magnetic shielding outer cover for sound boxes. Background technique [0002] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it to the space. It is an extremely important part of the audio system because it is responsible for converting electrical signals into acoustic signals. With the development of technology, there are more and more styles of speakers, and more and more functions. However, most of the existing speakers are not waterproof, so it is easy to cause the speaker to be damaged. damage. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a waterproof magnetic shielding cover for the sound box, which has a simple structure, can be disassembled, has good sea...
