[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an audio shell, including a shell body 2 and a mesh cover 1, the top side of the shell body 2 has an opening, and a card slot 23 arranged around the opening is provided on the side wall of the shell body 2, and the card slot 23 is provided with an anti-fool protrusion 24 protruding toward the top side of the shell body 2 on one side of the first direction. Figure 2 D1 in represents the first direction.

[0027] like Figure 2 、 Figure 4 and Figure 5 As shown, the mesh cover 1 includes a plate body 12 and a snap-fit ​​edge 13 connected to the outer peripheral edge of the plate body 12. The plate body 12 is provided with a sound outlet 11. The snap-fit ​​edge 13 extends toward one side of the shell body 2. The snap-fit ​​edge 13 is stuck in the slot 23. The snap-fit ​​edge 13 is provided with a notch 14 on one side in the first direction for avoiding the anti-fool protrusion 24.

[0028] Since the slot 23 is only provided with the anti-foolproof protrusion 24 on one side in the first direction, and the mesh cover 1 is only provided with the notch 14 on one side in the first direction for avoiding the anti-foolproof protrusion 24, therefore, only when the mesh cover 1 is assembled in the correct direction, that is, the side of the mesh cover 1 provided with the notch 14 corresponds to the side of the slot 23 provided with the anti-foolproof protrusion 24, the anti-foolproof protrusion 24 can be installed into the notch 14 on the mesh cover 1, so that the locking edge 13 is locked in the slot 23, thereby realizing the correct assembly of the mesh cover 1 and the shell body 2.

[0029] When the grille 1 is assembled in the opposite direction, since the grille 1 is not provided with the notch 14 on the other side of the first direction, the grille 1 on the other side of the first direction cannot avoid the anti-mistake protrusion 24 when the grille 1 is inserted into the slot 23. Therefore, the locking edge 13 cannot be inserted into the slot 23 of the shell body 2 in an upside-down posture, thereby avoiding the grille 1 from being installed incorrectly or upside down, and further avoiding the situation where rework is needed due to upside-down installation to damage the appearance of the audio shell, saving rework time and cost.

[0030] In the audio shell of the present invention, since the slot 23 of the shell body 2 is only provided with the anti-foolproof protrusion 24 on one side in the first direction, and the notch 14 for avoiding the anti-foolproof protrusion 24 is only provided on one side in the first direction on the grille 1, therefore, only when the assembly direction of the grille 1 is correct, that is, the side of the grille 1 with the notch 14 corresponds to the side of the slot 23 with the anti-foolproof protrusion 24, the anti-foolproof protrusion 24 can be installed into the notch 14 on the grille 1, so that the locking edge 13 is locked in the slot 23, and the assembly of the grille 1 and the shell body 2 is realized. When the grille 1 is assembled in the opposite direction, the locking edge 13 cannot be locked in the slot 23, avoiding the situation of wrong installation and reverse installation, and further avoiding the situation that rework is needed due to reverse installation to damage the appearance of the audio shell, saving rework time and cost.

[0031] In one embodiment, if Figure 3 、 Figure 4 and Figure 6 As shown, the outer side wall of the locking edge 13 abuts against one side wall of the locking groove 23, and an inner abutting portion 15 is provided on the inner side wall of the locking edge 13 on the other side of the first direction. The inner abutting portion 15 protrudes toward the center direction of the plate body 12 and abuts against the other side wall of the locking groove 23.

[0032] When the assembler installs the mesh cover 1 into the slot 23 in the opposite assembly direction with a greater assembly pressure, since the outer wall of the locking edge 13 and the inner abutment portion 15 abut against the side walls of the slot 23 on both sides, it can prevent the other side of the locking edge 13 from being deformed under the action of the greater assembly pressure to avoid the anti-fool protrusion 24, thereby avoiding the mesh cover 1 from being forcibly installed upside down under a greater assembly pressure.

[0033] In one embodiment, the middle portion of the engaging edge 13 on the other side of the first direction is bent toward the center of the plate body 12 to form the inner abutting portion 15 . The inner abutting portion 15 is integrally formed to facilitate processing.

[0034] In one embodiment, if Figure 6As shown, the inner abutting portion 15 includes a straight edge portion 16 and a curved portion 17. The straight edge portion 16 extends along the opening direction of the shell body 2. The curved portion 17 connects the top end of the straight edge portion 16 and the plate body 12. The straight edge portion 16 abuts against the sidewall of the slot 23. The contact area between the straight edge portion 16 and the sidewall of the slot 23 is large, further reducing the gap between the other side of the engaging edge 13 and the sidewall of the slot 23. As a result, the sidewall of the slot 23 better prevents the engaging edge 13 from deforming on the other side of the first direction.

[0035] In one embodiment, if Figure 2 As shown, the notch 14 is in the shape of an elongated strip extending along the second direction, wherein the second direction is perpendicular to the first direction and the opening direction of the housing body 2. The elongated notch 14 is larger and more obvious, making it easier to determine the assembly direction of the mesh cover 1. Figure 2 D2 in represents the second direction.

[0036] In one embodiment, if Figure 2 As shown, the fool-proof protrusion 24 includes a plurality of sub-protrusions arranged at intervals along the second direction.

[0037] In one embodiment, the sub-protrusion is in the shape of a column extending along the opening direction of the shell body 2, and the top end of the sub-protrusion is provided with a chamfer.

[0038] In one embodiment, if Figure 2 and Figure 3 As shown, the housing body 2 includes a bottom housing 21 and a bracket 22, which is mounted on the top side of the bottom housing 21. The bracket 22 includes a bracket body 221 and a bracket step 222 arranged around the outer wall of the bracket body 221. The bracket step 222, the outer wall of the bracket body 221, and the inner wall of the bottom housing 21 together form a slot 23, and an anti-fouling protrusion 24 is provided on the bracket step 222.

[0039] In one embodiment, the shell body 2 is in an elongated strip shape, the first direction is the length direction of the shell body 2 , and the second direction is the width direction of the shell body 2 .

[0040] In one embodiment, limiting protrusions protruding toward the center of the plate body 12 are provided on opposite sides of the engaging edge 13 in the second direction. The limiting protrusions abut against the side walls of the engaging slot 23 to limit the movement of the mesh cover 1.

[0041] In one embodiment, a plurality of sound holes 11 are provided, and the plurality of sound holes 11 are arranged on the plate body 12 in an array.

[0042] In other embodiments, the other side of the engaging edge 13 in the first direction may be a straight edge extending along the opening direction of the shell body 2 .

[0043] In other embodiments, the inner abutting portion 15 may be formed by excess material on the inner sidewall of the engaging edge 13 on the other side in the first direction.

[0044] In other embodiments, the inner abutting portion 15 may be an arc-shaped portion, and the center of the arc-shaped portion is located on a side away from the center of the shell body 2 .

[0045] In other embodiments, the notch 14 may be semicircular, square, oval or other irregular shapes.

[0046] In other embodiments, the fool-proof protrusion 24 may be in the shape of a long strip extending continuously along the second direction, and the length of the notch 14 is not less than the length of the fool-proof protrusion 24 .

[0047] In other embodiments, the sub-protrusion may be a sphere, a hemisphere, a block, etc.

[0048] In other embodiments, the shell body 2 may be cylindrical, elliptical, square, etc.
