A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0032] like Figures 1 to 8As shown, the mesh cover detachable speaker of the embodiment of the present invention includes a shell 1 and a mesh cover 2, the shell 1 has a accommodating cavity 11, and the shell 1 is provided with at least one installation opening 12 communicating with the accommodating cavity 11; the mesh cover 2 includes a mesh 21 and a rubber block 22, the mesh 21 is sleeved on the outside of the shell 1, and the mesh 21 is provided with a avoidance opening at a position corresponding to the installation opening 12, the cavity wall of the avoidance opening is provided with a rubber block 22 protruding toward the central axis of the avoidance opening, and the rubber block 22 is rotated toward the accommodating cavity 11 along the connection point between the mesh 21 and the rubber block 22, and the rubber block 22 can form a clamping groove 23 with the inner side surface of the mesh 21, the cavity wall of the installation opening 12 and the outer side surface of the shell 1 are set at an acute angle and form a clamping portion 13, and the clamping portion 13 is clamped in the clamping groove 23.

[0033] It can be understood that by setting a rubber block 22 on the avoidance opening of the mesh 21, when the mesh 21 is sleeved on the outside of the shell 1, the rubber block 22 is bent to form a hook structure with a clamping groove 23 with the mesh 21, which can be clamped on the clamping portion 13 formed by the cavity wall of the installation opening 12 and the outer side surface of the shell 1 at an acute angle, thereby realizing the installation of the mesh cover 2 and the shell 1. The installation is convenient, and the mesh 21 is prevented from being easily blocked by glue by gluing, thereby ensuring the yield rate of the audio production; the rubber block 22 is bent to separate the rubber block 22 from the installation opening 12, so that the mesh cover 2 is separated from the clamping connection with the shell 1, and the mesh cover 2 can be taken out for cleaning or replacement and other maintenance to ensure the cleanliness of the mesh cover 2, thereby ensuring the sound effect and aesthetics of the audio.

[0034] In addition, if Figure 6 、 Figure 7 and Figure 8 As shown, in addition to making the rubber block 22 and the mesh 21 form a hook structure with a snap-fit ​​groove 23 that can be snapped onto the snap-fit ​​portion 13 formed by the cavity wall of the installation opening 12 and the outer side surface of the shell 1 at an acute angle, the snap-fit ​​portion 13 can also be formed by connecting the cavity wall of the accommodating cavity 11, the cavity wall of the installation opening 12 and the outer side surface of the shell 1. The snap-fit ​​portion 13 is snapped into the snap-fit ​​groove 23 to achieve the installation of the mesh cover 2 and the shell 1. The installation is convenient, and the rubber block 22 is snapped into the accommodating cavity 11, making the snap-fit ​​more stable, effectively ensuring the connection strength between the mesh cover 2 and the shell 1. It should be noted that no matter which solution is adopted, the rubber block 22 is made of plastic with a certain structural hardness, so that when the rubber block 22 is rotated to fit the cavity wall, the structural strength of the hook structure set at an angle between the rubber block 22 and the mesh 21 is higher.

[0035] Furthermore, a rubber block 22 is provided in a circular protrusion on the wall of the escape opening, surrounding the central axis of the escape opening. By providing the annular rubber block 22, when the rubber block 22 is folded onto the wall of the accommodating cavity 11, an annular hook structure is formed between the annular rubber block 22 and the mesh 21 to clamp the inner and outer sides of the entire installation opening 12. The clamping is stable, ensuring the stability of the tension of the mesh 21 at various positions at the installation opening 12, making it difficult to pull out the rubber block 22, and effectively improving the connection strength between the mesh cover 2 and the housing 1.

[0036] Of course, in other embodiments, multiple rubber blocks 22 may be annularly spaced around the central axis of the escape opening, and the multiple rubber blocks 22 and the mesh 21 may form multiple hook structures to achieve a secure connection between the mesh cover 2 and the housing 1. Furthermore, when the rubber blocks 22 and the mesh 21 form a hook structure having a slot 24 that is secured to the mounting opening 12, the annular hook structure formed between the rubber blocks 22 and the mesh 21 can also enhance the stability of the engagement between the mesh cover 2 and the mounting opening 12.

[0037] Furthermore, if Figure 6 and Figure 7 As shown, when the rubber block 22 is connected to the wall of the accommodating cavity 11, a plurality of latching spikes 14 are spaced apart on the wall of the accommodating cavity 11, and the plurality of latching spikes 14 are evenly distributed around the central axis of the mounting opening 12, so that the latching spikes 14 can latch onto the rubber block 22. The rubber block 22 has a certain degree of adhesion and deformability, and can be attached to the wall of the accommodating cavity 11 to achieve a certain degree of adhesion. By using the latching spikes 14 to pierce the rubber block 22 and insert it into the rubber block 22, the latching spikes 14 latch onto the rubber block 22, thereby preventing the mesh 21 from pulling and separating the rubber block 22 from the wall of the accommodating cavity 11. This can effectively enhance the connection strength between the rubber block 22 and the housing 1, thereby ensuring the stability of the connection between the mesh cover 2 and the housing 1. Of course, in the scheme where the rubber block 22 is latched onto the wall of the mounting opening 12, the wall of the mounting opening 12 can also be provided with latching spikes 14 to enhance the stability of the connection between the rubber block 22 and the wall of the mounting opening 12.

[0038] Preferably, the thorn 14 has a free end and a fixed end connected to the cavity wall of the accommodating cavity 11. The thorn 14 is inclined from the fixed end toward the free end and toward the center axis away from the installation port 12. On the one hand, it can reduce the obstruction when the rubber block 22 is connected to the cavity wall of the accommodating cavity 11, and can even guide the rubber block 22 to move along the inclined thorn 14 in the direction away from the installation port 12; on the other hand, the rubber block 22 has a pulling force toward the center axis of the installation port 12 under the pulling of the mesh 21, and the inclination of the thorn 14 in the direction away from the installation port 12 can provide a supporting force in the opposite direction, thereby improving the connection stability between the thorn 14 and the rubber block 22.

[0039] Optionally, a slot 24 is provided on the side of the rubber block 22 facing the cavity wall of the accommodating chamber 11, and the thorn 14 is engaged with the slot 24. The provision of the slot 24 allows the thorn 14 to be directly engaged with the slot 24, reducing the damage caused by the thorn 14 to the structure of the rubber block 22 and improving the connection convenience between the thorn 14 and the rubber block 22. Furthermore, if the rubber block 22 is provided with a slot 24, the sharp-pointed thorn 14 can be configured as a buckle. Engaging the buckle with the slot 24 can achieve a secure connection between the housing 1 and the mesh cover 2, reducing damage to the rubber block 22. After disassembly and cleaning, the mesh cover 2 can be reused, thereby improving the continued utilization rate of the mesh cover 2.

[0040] In some embodiments, a limiting groove is provided on the cavity wall of the accommodating cavity 11 corresponding to the position of the rubber block 22, and the rubber block 22 is arranged in the limiting groove. That is, the limiting groove avoids the rubber block 22, which can reduce the space occupied by the rubber block 22 in the accommodating cavity 11.

[0041] Furthermore, the mesh 21 is an elastic mesh 21 composed of a mixture of three materials: thermoplastic elastomer, polyethylene, and polypropylene. The thermoplastic elastomer accounts for 50%-72% by weight, the polyethylene accounts for 14%-25% by weight, and the polypropylene accounts for 14%-25% by weight. This elastic mesh 21 composed of thermoplastic elastomer, polyethylene, and polypropylene exhibits excellent tensile ductility and elasticity. The thermoplastic elastomer is one of a propylene-based elastomer, a styrene-based elastomer, or a thermoplastic polyurethane elastomer rubber with good castability. It is worth noting that the mesh 21 is typically slightly smaller than the outer dimensions of the housing 1, requiring the elastic mesh 21 to be pulled and installed. Therefore, the provision of the elastic mesh 21 not only improves the fit of the mesh 21 to the housing 1 and prevents the mesh 21 from sagging against the surface of the housing 1, but also increases the margin of production tolerances for the mesh 21, reducing the scrap rate of the mesh 21 and saving production costs. Furthermore, the elastic mesh 21 is more resistant to external impact than a rigid mesh 21, effectively extending its service life.

[0042] In other embodiments, Figure 6 and Figure 8 As shown, the mesh cover 2 further includes positioning rubber posts 25. A plurality of positioning rubber posts 25 are connected to the side of the mesh 21 facing the housing 1. Positioning holes 15 corresponding to the positioning rubber posts 25 are formed on the outside of the housing 1, and the positioning rubber posts 25 are inserted into the positioning holes 15. Inserting the positioning rubber posts 25 into the positioning holes 15 enhances the connection strength between the mesh 21 and the housing 1. Furthermore, the positioning rubber posts 25 share the elastic pulling force of the mesh 21, thereby reducing the pulling force of the mesh 21 on the rubber block 22 and further enhancing the overall installation stability of the mesh cover 2.

[0043] Furthermore, the positioning hole 15 communicates with the accommodating cavity 11, and the positioning rubber column 25 includes a connecting portion 251 and a stopping portion 252. The connecting portion 251 is connected to the mesh 21, and the stopping portion 252 is provided at the end of the connecting portion 251 away from the mesh 21. The connecting portion 251 has a first end face connected to the stopping portion 252, and the stopping portion 252 has a second end face 2521 connected to the connecting portion 251 and a third end face away from the connecting portion 251. The diameter of the second end face 2521 is greater than the diameter of the first end face and greater than the diameter of the positioning hole 15. The second end face 2521 abuts against the cavity wall of the accommodating cavity 11, and the diameter of the third end face is smaller than the diameter of the positioning hole 15. By using the second end face 2521 of the stopping portion 252 to abut against the cavity wall of the accommodating cavity 11, the positioning rubber column 25 can be prevented from falling out of the positioning hole 15, further improving the connection strength between the positioning rubber column 25 and the housing 1, thereby improving the connection strength between the mesh cover 2 and the housing 1.

[0044] Furthermore, by configuring the diameter of the third end surface of the stopper 252 to be smaller than the diameter of the positioning hole 15, while configuring the diameter of the second end surface 2521 to be larger than the diameter of the positioning hole 15, i.e., configuring the stopper 252 to be truncated, the stopper 252 is facilitated in passing through the positioning hole 15. Optionally, the diameter of the connecting portion 251 is slightly larger than the diameter of the positioning hole 15, and the connecting portion 251 has a certain degree of elasticity. This ensures that when the connecting portion 251 is inserted into the positioning hole 15, the connection strength between the connecting portion 251 and the positioning hole 15 is maintained, while also sealing the connecting hole and reducing the impact of the opening structure on the acoustic performance.

[0045] Furthermore, an extrusion hole 253 is further formed on the third end surface of the stopping portion 252 , so that the stopping portion 252 can be elastically deformed and inserted into the accommodating cavity 11 in a better manner.

[0046] The steps for installing the speaker with detachable grille of the utility model include:

[0047] S10, placing the housing 1 of the speaker with detachable grille steadily on a workbench;

[0048] S20, placing the mesh 21 of the mesh cover 2 of the detachable mesh cover speaker outside the housing 1, and adjusting the position of the mesh 21 so that the avoidance opening of the mesh 21 corresponds to the installation opening 12 of the housing 1;

[0049] S30, moving the rubber block 22 of the mesh cover 2 along the installation opening 12, so that the rubber block 22 rotates toward the accommodating cavity 11 of the shell 1 and forms a snap-fit ​​groove 23 with the mesh 21 at an acute angle, and the snap-fit ​​groove 23 is snap-fitted to the snap-fit ​​portion 13 formed by the cavity wall of the installation opening 12 and the outer side surface of the shell 1 at an acute angle, thereby achieving the connection between the mesh cover 2 and the shell 1; or,

[0050] The rubber block 22 of the mesh cover 2 is bent along the installation opening 12 so that the rubber block 22 rotates toward the accommodating cavity 11 of the shell 1 and forms a snap-fit ​​groove 23 with the mesh cloth 21, and the snap-fit ​​groove 23 is snapped onto the snap-fit ​​portion 13 formed by connecting the cavity wall of the accommodating cavity 11 of the shell 1, the cavity wall of the installation opening 12 and the outer side surface of the shell 1, thereby realizing the connection between the mesh cover 2 and the shell 1.

[0051] By bending the rubber block 22 of the mesh cover 2, the hook structure with the clamping groove 23 formed by the rubber block 22 and the mesh cloth 21 can be clamped on the clamping part 13 formed by the cavity wall of the installation port 12 and the outer side surface of the shell 1 at an acute angle, or clamped on the clamping part 13 formed by connecting the cavity wall of the accommodating cavity 11, the cavity wall of the installation port 12 and the outer side surface of the shell 1, thereby realizing the installation of the mesh cover 2 and the shell 1. The installation is convenient, time-saving and labor-saving, and can also avoid the situation where the mesh cloth 21 is easily blocked by glue to ensure the yield rate of audio production.
