[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] like Figures 1 to 8 As shown, the detachable grille speaker of the embodiment of the present invention comprises a shell 1 and a grille 2, wherein the shell 1 has a accommodating cavity 11, and the shell 1 is provided with at least one mounting opening 12 communicating with the accommodating cavity 11; the grille 2 comprises a mesh 21 and a rubber block 22, the mesh 21 is sleeved on the outer side of the shell 1, and a avoidance opening is provided at a position of the mesh 21 corresponding to the mounting opening 12, the cavity wall of the avoidance opening is provided with a rubber block 22 protruding toward the central axis direction of the avoidance opening, 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 mounting opening 12 and the outer side surface of the shell 1 are arranged at an acute angle to form a clamping portion 13, and the clamping portion 13 is clamped in the clamping groove 23.

[0038] 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 outside the shell 1, the rubber block 22 is bent so that the rubber block 22 and the mesh 21 form a hook structure with a snap-in groove 23, which can be snap-fitted on the snap-in 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 easily blocking the sound hole of the shell 1 by gluing, thereby ensuring the yield rate of the audio production; the rubber block 22 is bent so that the rubber block 22 is separated from the installation opening 12, and the mesh cover 2 is separated from the snap-in connection with the shell 1, so that the mesh cover 2 can be taken out for cleaning or replacement and other maintenance, so as to ensure the cleanliness of the mesh cover 2, thereby ensuring the sound effect and aesthetics of the audio.

[0039] In addition, if Figure 6 , Figure 7 and Figure 8As 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, and 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, which is convenient for installation, and the rubber block 22 is snapped into the accommodating cavity 11, and the snap-fit ​​is more stable, which effectively ensures 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 rotates to fit the cavity wall, the hook structure of the rubber block 22 and the mesh 21 at an angle has a higher structural strength.

[0040] Furthermore, the cavity wall of the avoidance opening is provided with a rubber block 22 in a ring-shaped protrusion around the central axis of the avoidance opening. By providing the ring-shaped rubber block 22, when the rubber block 22 is folded to the cavity wall of the accommodating cavity 11, a ring-shaped hook structure is formed between the ring-shaped rubber block 22 and the mesh 21 to clamp the inner and outer sides of the entire installation opening 12, and the clamping is stable, ensuring the stability of the tension of the mesh 21 at various positions at the installation opening 12, and it is not easy to pull out the rubber block 22, thereby effectively improving the connection strength between the mesh cover 2 and the shell 1.

[0041] Of course, in other embodiments, multiple rubber blocks 22 may be arranged at annular intervals around the central axis of the avoidance opening on the cavity wall of the avoidance opening, and multiple rubber blocks 22 and mesh 21 may be used to form multiple hook structures to achieve a stable connection between the mesh cover 2 and the housing 1. In addition, when the rubber block 22 and the mesh 21 form a hook structure with a slot 24 that is clamped at the installation opening 12, the ring-shaped rubber block 22 and the mesh 21 can also form a ring-shaped hook structure that can improve the stability of the clamping of the mesh cover 2 and the installation opening 12.

[0042] Furthermore, if Figure 6 and Figure 7 As shown, when the rubber block 22 is connected to the cavity wall of the accommodating cavity 11, a plurality of thorns 14 are arranged at intervals on the cavity wall of the accommodating cavity 11, and the plurality of thorns 14 are evenly arranged around the central axis of the installation port 12, and the thorns 14 can be engaged with the rubber block 22. The rubber block 22 has certain adhesiveness and deformation ability, and the rubber block 22 can be attached to the cavity wall of the accommodating cavity 11 to a certain extent. The thorns 14 can pierce the rubber block 22 and insert it into the rubber block 22, so that the thorns 14 can engage the rubber block 22, thereby preventing the mesh 21 from pulling and separating the rubber block 22 from the cavity wall of the accommodating cavity 11, which can effectively improve the connection strength between the rubber block 22 and the shell 1, thereby ensuring the connection stability of the mesh cover 2 and the shell 1. Of course, in the scheme where the rubber block 22 is engaged on the cavity wall of the installation port 12, the thorns 14 can also be arranged on the cavity wall of the installation port 12 to enhance the stability of the connection between the rubber block 22 and the cavity wall of the installation port 12.

[0043] 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 central 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 away from the installation port 12; on the other hand, the rubber block 22 has a pulling force in the direction of the central axis of the installation port 12 under the pulling of the mesh cloth 21, and the inclination of the thorn 14 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.

[0044] Optionally, a slot 24 is provided on one side of the wall of the rubber block 22 facing the accommodating cavity 11, and the thorn 14 is engaged in the slot 24. By providing the slot 24, the thorn 14 can be directly engaged in the slot 24, reducing the destructiveness of the thorn 14 to the structure of the rubber block 22, and improving the convenience of connecting the thorn 14 and the rubber block 22. In addition, when the rubber block 22 is provided with the slot 24, the thorn 14 with a sharp structure can be provided as a buckle, so that the buckle is engaged with the slot 24 to achieve a stable connection between the housing 1 and the mesh cover 2, reducing the damage to the rubber block 22, so that it can be used again after disassembly and cleaning, and improving the continuous utilization rate of the mesh cover 2.

[0045] 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, so that the space occupied by the rubber block 22 in the accommodating cavity 11 can be reduced.

[0046] Furthermore, the mesh 21 is an elastic mesh 21 composed of a mixture of three materials: thermoplastic elastomer, polyethylene and polypropylene, wherein the mass of the thermoplastic elastomer accounts for 50%-72%, the mass of the polyethylene accounts for 14%-25%, and the mass of the polypropylene accounts for 14%-25%. The elastic mesh 21 composed of the thermoplastic elastomer, polyethylene and polypropylene has good tensile ductility and elasticity, and the thermoplastic elastomer is one of propylene-based elastomer, styrene, and thermoplastic polyurethane elastomer rubber with good casting processability. It is worth noting that the size of the mesh 21 is usually slightly smaller than the size of the outer side of the shell 1, and the elastic mesh 21 needs to be pulled for sleeve installation. Therefore, the setting of the elastic mesh 21 can, on the one hand, improve the fit between the mesh 21 and the shell 1, and prevent the mesh 21 from loosening to the surface of the shell 1; on the other hand, it can improve the redundancy of the production tolerance of the mesh 21, reduce the scrap rate of the mesh 21 production, and save production costs. And the elastic mesh 21 is more resistant to external impact than the hard mesh 21, which effectively improves the service life of the mesh 21.

[0047] In other embodiments, Figure 6 and Figure 8As shown, the mesh cover 2 further includes positioning rubber columns 25, and a plurality of positioning rubber columns 25 are connected to the side of the mesh 21 facing the housing 1. Positioning holes 15 are provided on the outer side of the housing 1 corresponding to the positioning rubber columns 25, and the positioning rubber columns 25 are inserted into the positioning holes 15. By inserting the positioning rubber columns 25 into the positioning holes 15, the connection strength between the mesh 21 and the housing 1 is improved; at the same time, the positioning rubber columns 25 share the elastic pulling force of the mesh 21, which can reduce the pulling force of the mesh 21 on the rubber block 22, and further improve the overall installation stability of the mesh cover 2.

[0048] Further, the positioning hole 15 is communicated 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 one 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 is tightly pressed 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 stop at the cavity wall of the accommodating cavity 11, the positioning rubber column 25 can be prevented from falling out of the positioning hole 15, and the connection strength between the positioning rubber column 25 and the shell 1 is further improved, thereby improving the connection strength between the mesh cover 2 and the shell 1.

[0049] In addition, by setting the diameter of the third end face of the stopper 252 to be smaller than the diameter of the positioning hole 15, and the diameter of the second end face 2521 to be larger than the diameter of the positioning hole 15, that is, the stopper 252 is set in a truncated cone, it is convenient for the stopper 252 to pass 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 elasticity, so 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 can be guaranteed, and the connecting hole can be blocked at the same time, reducing the influence of the opening structure on the sound effect.

[0050] Furthermore, an extrusion hole 253 is further formed on the third end surface of the stopper 252 , so that the stopper 252 can be elastically deformed to be inserted into the accommodating cavity 11 .

[0051] An embodiment of the present invention further provides a method for installing a speaker with a detachable grille, providing the above-mentioned speaker with a detachable grille, comprising the following steps:

[0052] S10, placing the housing 1 of the speaker with detachable grille steadily on a workbench;

[0053] S20, putting 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;

[0054] 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 cloth 21 at an acute angle, and the snap-fit ​​groove 23 is snap-fitted on 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,

[0055] 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-in groove 23 with the mesh cloth 21, and the snap-in groove 23 is snapped on the snap-in 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.

[0056] The method can achieve installation of the mesh cover 2 and the shell 1 by bending the rubber block 22 of the mesh cover 2 so that 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 opening 12 and the outer side surface of the shell 1 at an acute angle, or by clamping on the clamping part 13 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, thereby facilitating the installation, saving time and effort, and preventing the mesh cloth 21 from being easily blocked by glue to ensure the yield rate of the audio production.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
