Problems solved by technology

[0003] Metal wire braided mesh is relatively soft and difficult to shape. Because it is braided, the wire gap is easy to be loosened by pressure or tension, or the wire is drawn to deform the braided mesh. Even after stamping into a certain shape, it is difficult to Easily deformed by extrusion
Especially in some cases, the surface of the speaker needs to be a curved surface, such as a hemispherical or semi-elliptical spherical mask, so it is more difficult to use a wire woven mesh as a surface mesh
Therefore, there is no speaker with wire braided mesh as the surface mesh at present.

Embodiment 1

[0031] figure 1 A spherical sound box structure adopted by the present invention is shown, and the main components include: a face shield composed of a face net 11 and a supporting set 12 , and a sound box body 14 including a speaker unit 141 . The face net 11 is made of braided iron netting, which is formed into a hemispherical shape through preliminary stamping. The edge 111 of the face net 11 is bent, surrounds the inner side of the supporting set 12, and is glued on the supporting set 12 through punching to form a complete mask, which is assembled on the sound box body 14 to form a spherical sound box.

[0032] Specifically, the supporting sleeve 12 is hollow inside and is composed of an outer wall 121 , an inner wall 122 and a bottom edge 123 , forming a circumferential groove. The edge 111 of the surface net 11 is bent, surrounds the edge 126 of the outer wall, and is glued on it by stamping, so that the surface net 11 is stretched tightly to surround the outer wall 12...

Embodiment 2

[0034] figure 2 A preferred mode of Embodiment 1 is shown, that is, the face mask also includes a connecting piece 23, which is arranged between the support kit 12 and the sound box body 14, and the four cylindrical legs 232 of the connecting piece 23 are inserted into the corresponding positions of the sound box body 14 In the four mounting holes of the cover, the mask can be assembled on the sound box body 14. image 3 Shown is the assembly structure of the connecting piece 23 and the supporting sleeve 12. There are four protruding points 231 on the inner surface of the connecting piece 23 corresponding to the four rectangular openings 125, and the 125 and 231 are engaged to make the wall 233 of the connecting piece It is fixed in the circumferential groove between the outer wall 121 and the inner wall 122 of the supporting sleeve. This assembly structure is more convenient and firmer than the first embodiment, and has better airtightness.

Embodiment 3

[0037] Such as Figure 4 with Figure 5 Shown are a perspective view and a sectional view of the assembly fixture, respectively. The clamp is composed of a clamp body 31 , a movable part 32 , a spring 33 and a latch 34 . The head of the fixture body 31 has a shape that matches the speaker grille. In this embodiment, the head 31 matches the speaker grille 11 of Embodiment 2. It is a semi-ellipsoidal solid body, and the middle and lower parts are cylinders. body, the middle embedded movable part 32 and four springs 33 (such as Image 6 As shown), the movable part 32 and the spring 33 can be moved therein, and the lower part has a cavity into which the latch 34 can be inserted.

[0038] Such as Image 6 As shown, the movable member 32 has four telescopic parts 321 and a central part 322 fixed to the clamp body 31 , the spring 33 connects the telescopic parts 321 and the central part 322 , and the telescopic parts 321 are displaced by elastic deformation. There is a groove 324 ...

Abstract

The present invention proposes a sound box with a woven surface net, comprising a sound box body on which a speaker unit is installed and a face mask assembled on the front of the sound box body, and the face shield includes a woven surface net made of a metal wire braided net and a hollow supporting sleeve , the support sleeve includes an inner wall, an outer wall and a bottom edge, and forms a closed groove, the woven surface net surrounds the outer wall, its edge is bent into the inner side of the outer wall, and is stamped and fixed on the outer wall, so that The surface net is stretched and fixed on the support kit. The woven metal mesh has the characteristics of flexibility and toughness, which can better shape the appearance of the speaker, and its good air and sound permeability can reduce the interference and attenuation of the sound by the mesh. The invention also proposes a special fixture and assembly method for the sound box to ensure that the grille does not deform during the assembly process.

Description

technical field [0001] The invention relates to a sound box with a braided surface net, an assembly fixture and an assembly method thereof, in particular to a sound box with a metal wire braided surface net and an assembly fixture and an assembly method specially used for its mask. Background technique [0002] The sound box usually has a mask to prevent the front surface of the sound box and the speaker unit mounted on it from being polluted by dust and accidental damage. Masks are usually made of a porous, less sound-attenuating cloth mesh stretched over a plastic or iron frame, or made of iron mesh. Wire woven mesh includes wire woven dense mesh or metal wire woven square hole mesh, and the wire material is generally heat-treated pure nickel, brass, tin bronze, stainless steel and carbon structural steel. The weaving method is usually single-up and single-bottom or double-up and double-bottom or weft-knitted plain or twill, such as Figure 10 Shown is twill weave, a is s...
