Example one

Referring to fig. 1 to 4, the enclosure assembly of the sound box of the present embodiment mainly includes a housing 100, a mesh 200, and a cover 300.

The housing 100 is a hollow structure, and an inner cavity defined by the housing 100 is used for mounting a main board, a speaker, and the like. The present application does not specifically limit the external contour shape of the housing 100, and the present embodiment will be described by taking the housing 100 as a hollow cylindrical structure as an example. The housing 100 is provided with a first magnetic attraction portion 410.

The mesh 200 is provided with an opening 210, and the mesh 200 is provided with a plurality of second magnetic attraction parts 420 around the opening 210, so that the shell 100 can be placed in the mesh 200 through the opening 210 or taken out of the mesh 200 through the opening 210. When the housing 100 is placed inside the mesh 200, the second magnetic attraction portions 420 and the first magnetic attraction portions 410 attract each other correspondingly, and the mesh 200 wraps the periphery of the housing 100 at this time, so as to protect the housing 100 in all directions.

The cover 300 is placed on the mesh 200, a plurality of third magnetic attraction portions 430 are arranged on the cover 300, the third magnetic attraction portions 430 and the second magnetic attraction portions 420 attract each other correspondingly, and the opening 210 is shielded by the cover 300 at the moment so as to prevent the opening 210 from being opened under the action of external force.

When the mesh cloth 200 is installed, the outer shell 100 is placed in the mesh cloth 200 through the opening 210, and the first magnetic suction part 410 and the second magnetic suction part 420 are attracted correspondingly to realize the fixation between the mesh cloth 200 and the outer shell 100; then, the cover 300 is placed at the opening 210, the opening 210 is shielded by the cover 300, and the second magnetic attraction part 420 and the third magnet part 430 are attracted together. The mesh cloth 200 is firmly retained between the housing 100 and the cover 300 by the attraction between the first magnetic portion 410, the second magnetic portion 420 and the third magnetic portion 430.

When the mesh cloth 200 is replaced, the mesh cloth 200 can be detached from the housing 100 by simply taking down the cover 300 and opening the opening 210, so that the replacement is easy.

In some embodiments of the present application, referring to fig. 2 and 3, the housing 100 includes an upper shell 110 and a lower shell 120, and the upper shell 110 and the lower shell 120 are fixedly connected by means of a snap, a glue, or a screw. The housing contour defined by the upper housing 110 and the lower housing 120 has two end faces (upper end face and lower end face, respectively) facing each other up and down and a circumferential side face provided between the two end faces.

The first magnetic attraction portion 410 is disposed on the upper end surface 130, and accordingly, the opening 210 of the mesh and the cover 300 are also disposed on the upper end surface 130, so that the flatness of the lower end surface can be ensured, and the housing 100 can be placed more stably.

In some embodiments of the present application, referring to fig. 4, the mesh 200 is provided with elastic strings 220 around the openings 210, and the openings 210 can be narrowed by tightening the elastic strings 220. When establishing screen cloth 200 to the cover on shell 100, prop open earlier the elasticity rope 220, opening 210 enlarges, establish on shell 100 with screen cloth 200 cover, when opening 210 cover was established and is close to up end 130, loosen elasticity rope 220, utilize the shrink of elasticity rope 220 to realize that opening 210 reduces automatically, screen cloth 200 is automatic taut, automatic actuation of counterpointing can be realized to first magnetism portion 410 and second magnetism portion 420 of inhaling this moment, realize the installation of screen cloth 200, then install lid 300 can.

The elastic cord 220 can be used to keep the mesh cloth 200 in a relatively taut state, thereby further improving the reliability and flatness of the installation of the mesh cloth 200.

In some embodiments of the present application, referring to fig. 4, the plurality of second magnetic attraction parts 420 are disposed around the periphery of the elastic cord 220, so that when the opening 210 is tightened under the action of the elastic cord 220, the second magnetic attraction parts 420 are located in a tensioned range of the mesh cloth 200, and the attraction reliability between the second magnetic attraction parts 420 and the first magnetic attraction parts 410 can be ensured.

In some embodiments of the present application, referring to fig. 8, the number of the second magnetic attraction portions 420 is four, two of the second magnetic attraction portions 420 are close to each other and have opposite magnetic poles, and the other two second magnetic attraction portions 420 are close to each other and have opposite magnetic poles. Two second magnetism portion 420 of inhaling are a set of, and be close to each other and the magnetic pole is opposite, and two second magnetism portions 420 that are close to are also attracted each other for the top of screen cloth 200 is more taut, improves the planarization of screen cloth 200.

In some embodiments of the present application, referring to fig. 6, the housing 100 (specifically, the upper end surface 130) is provided with a first concave portion 140, and the first magnetic attraction portion 410 is disposed in the first concave portion 140. Referring to fig. 5, the cover 300 is provided with a second recess 310, and a third magnetic attraction part 430 is provided in the second recess 310. The first and

second recesses

140 and 310 can improve the mounting reliability of the first and third

magnetic attraction parts

410 and 430.

Referring to fig. 4, the second magnetic portion 420 is located between the first concave portion 140 and the second concave portion 310, so that the corresponding first magnetic portion 410, the second magnetic portion 420 and the third magnetic portion 430 can be aligned vertically, thereby further improving the reliability of the attraction and the installation reliability of the mesh cloth 200.

In some embodiments of the present application, referring to fig. 4, the height of the first concave portion 140 is greater than the height of the first magnetic attraction portion 410, and the height of the second concave portion 310 is greater than the height of the third magnetic attraction portion 430, so that when the cover 300 is installed in place, a certain space is left between the first magnetic attraction portion 410 and the third magnetic attraction portion 430, and the space is just used for accommodating the second magnetic attraction portion 420, and at this time, the lateral peripheral walls of the first concave portion 140 and the second concave portion 310 play a certain limit stop role for the second magnetic attraction portion 420, so as to further improve the attraction reliability, and improve the installation reliability of the mesh cloth 200.

In some embodiments of the present application, the first magnetic portion 410 and the third magnetic portion 430 are iron blocks, and the second magnetic portion 420 is a magnet. And, two adjacent second magnetism portion 420 of inhaling are opposite in magnetic pole, make two adjacent second magnetism portions 420 attract each other, help further improving the taut state of screen cloth 200, improve the planarization of screen cloth 200.
