Description

Technical Field

[0001] This application belongs to the field of vehicle interior technology, and more specifically, relates to a speaker mounting structure and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, people have increasingly higher requirements for the performance of in-car speakers. Good speakers can provide drivers and passengers with high-quality sound effects, thereby enhancing the driving experience.

[0003] As an important part of modern automotive interior design, speakers are typically fixed using bosses (pillars with threaded holes for screw fastening) on ​​the back of interior panels. For example, midrange speakers are fixed to the interior panels or speaker covers on the interior panels by multiple screws spaced around their perimeter.

[0004] However, this traditional method of relying solely on the number of screws to ensure the reliability of speaker mounting has many drawbacks. For example, using a large number of screws leads to long installation time and a high risk of screws falling off. At the same time, the installation space for each screw must be considered, which affects the optimal layout of the installation location and space. Utility Model Content

[0005] The purpose of this application is to provide a speaker mounting structure that reduces the amount of fasteners used, improves assembly efficiency, and optimizes space layout.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, embodiments of this application provide a loudspeaker mounting structure, comprising: The speaker cover is installed on the interior panel of the vehicle. The middle area of ​​the speaker cover has an array of sound-permeable holes. The speaker cover has a socket limiting part and a positioning fastening part on both sides of the array of sound-permeable holes. The speaker body is pressed onto the speaker cover corresponding to the sound-permeable hole array, and the two sides of the speaker body are respectively provided with insertion limiting part and positioning connection part; The socket limiting part and the insertion limiting part are inserted and fitted in a direction parallel to the speaker cover, and the positioning fastening part and the positioning connecting part are inserted and fixed by fasteners in a direction perpendicular to the speaker cover.

[0007] The beneficial effects of the speaker mounting structure provided in this application embodiment are that, compared with the prior art, the speaker cover, set on the interior panel of the vehicle, serves as both a decorative surface and a mounting base for the speaker body. The sound emitted from the acoustic cavity of the speaker body passes through the array of sound-transmitting holes on the speaker cover and enters the vehicle, thereby providing clear sound effects for the driver and passengers. The speaker body is inserted into the socket limiting part on one side of the speaker cover via an insertion limiting part, and simultaneously, the positioning connecting part on the other side of the speaker body is connected and fixed to the positioning fastening part on the speaker cover by fasteners. Since the insertion direction of the insertion limiting part and the socket limiting part is parallel to the speaker cover, and the insertion fixing direction of the positioning connecting part and the positioning fastening part is perpendicular to the speaker cover, the speaker body can be constrained in any direction in space. Thus, the speaker body can be reliably fixed to the speaker with only one fastener. Compared with the traditional mounting structure that requires multiple screws for fastening, this not only saves assembly time and helps to shorten the process cycle, thereby improving assembly efficiency, but also reduces the risk of fasteners falling off and the dependence on installation space, thus facilitating the optimization of the overall structural spatial layout.

[0008] In conjunction with the first aspect, in one possible implementation, the speaker cover has a bent rib on one side of the sound-permeable hole array, which serves as a socket limiting part. The bent rib arches on the surface of the speaker cover to form a socket. A first ear plate extends outward from one side edge of the speaker body and is inserted into the socket as an insertion limiting part.

[0009] In the above technical solution, the rib can be welded to the speaker cover later or integrally formed into the speaker cover. Structurally, the rib is an upward-arching inverted U-shape or arc, which allows the rib to form an insertion hole parallel to the speaker cover. After the first ear plate formed by the edge of the speaker body is inserted into the insertion hole, it can simultaneously form a constraint in the insertion direction and in the direction perpendicular to the speaker cover. This, combined with the cooperation between the positioning connection part on the other side of the speaker body and the positioning fastening part on the speaker cover, can ensure the stable installation of the speaker body on the speaker cover. The structure is simple, reliable, and convenient for assembly.

[0010] For example, the first ear plate gradually narrows in its extensional direction to form a trapezoidal plate, and the insertion hole is a trapezoidal hole adapted to the trapezoidal plate.

[0011] In the above technical solution, the first ear plate and the socket adopt a trapezoidal mating cross section. This allows the insertion depth of the first ear plate to be limited by the contact between the inclined surface of the trapezoidal plate and the inclined wall of the socket when the first ear plate is inserted into the socket. This limits the speaker body in the insertion direction, thereby easily achieving precise alignment of the positioning connection part and the positioning fastening part, which helps to save alignment time and improve assembly efficiency.

[0012] In some embodiments, the speaker cover is provided with a raised limiting frame, and the inside of the limiting frame forms a clearance space suitable for the first ear plate to extend into; the two ends of the bent rib are respectively connected to the two side walls of the limiting frame, and a plug-in port is formed between the bent rib and the side wall of the limiting frame facing the sound-transmitting hole array; wherein, the first ear plate is adapted to extend into the clearance space at an angle through the plug-in port and swing out of the clearance space when it comes into contact with the bent rib and presses against the limiting frame.

[0013] In the above technical solution, the limiting frame can be welded to the surface of the speaker cover later, or it can be directly integrally formed with the speaker cover; the limiting frame can be a rectangular frame, a trapezoidal frame or other shapes, and the limiting frame can be a circumferentially semi-open frame or a circumferentially fully closed frame. When installing the speaker body, the first ear plate is first inserted into the clearance space through the insertion port at an angle. Since the first ear plate is a trapezoidal plate, the part of the first ear plate that passes through the insertion port gradually widens as it is inserted into the port. When the first ear plate abuts against the curved rib, it means that it is inserted in place. At this time, the speaker body is swung to a state parallel to the speaker cover. During this process, the part of the first ear plate that extends into the clearance space swings out and abuts against the arched part of the curved rib. Thus, the curved rib and the limiting frame limit the first ear plate in the direction perpendicular to the speaker cover. Since the inclined surface of the first ear plate abuts against the curved rib in the insertion direction, it also limits the position in that direction. This ensures that the positioning connection part on the opposite side of the first ear plate is aligned with the positioning fastening part, which facilitates the subsequent insertion of the positioning connection part and the positioning fastening part and the connection of the fasteners.

[0014] In conjunction with the first aspect, in one possible implementation, a second ear plate is formed by extending one side edge of the speaker body. The second ear plate is provided with positioning holes and connecting holes at intervals to form a positioning connection part. The positioning fastening part includes a positioning post and a fixing post. The positioning post is inserted into the positioning hole, and the fixing post abuts against the second ear plate and is aligned with the connecting hole. The fastener passes through the connecting hole and is screwed into the fixing post.

[0015] In the above technical solution, the second ear plate formed by extending the edge of the speaker body provides a position for the positioning hole and the connecting hole. After the insertion limiting part and the socket limiting part are engaged, the positioning hole is sleeved on the positioning post, and the fastener passing through the connecting hole is screwed into the fixing post to fix the speaker body. The engagement between the positioning post and the positioning hole can form a positioning constraint in any direction parallel to the speaker cover, while the screw connection between the fastener passing through the connecting hole and the fixing post can form a fastening constraint in a direction perpendicular to the speaker cover. A single fastener can achieve a reliable connection of the speaker body on the speaker cover. The installation method is simple and reliable, which is conducive to optimizing the spatial layout and improving the efficiency of assembly operations.

[0016] For example, the fixing column includes a core column and a number of reinforcing ribs distributed circumferentially around the outer periphery of the core column. The core column is adapted to pass through the connecting hole and be screwed into the fastener. Each reinforcing rib abuts against and is supported by the second ear plate.

[0017] In the above technical solution, the core column and the reinforcing rib can be integrally formed on the speaker cover. The core column has a threaded hole in the center for screwing and fixing with fasteners. The function of the reinforcing rib is to improve the connection strength between the core column and the speaker cover, and to provide support for the second ear plate. This allows the fasteners and the reinforcing rib to work together to clamp the second ear plate, preventing the second ear plate from being suspended and subjected to force, which would affect the overall connection structure strength.

[0018] For example, the positioning column includes multiple intersecting vertical bars, each vertical bar including a support section and a positioning section; wherein, the support section of each vertical bar abuts against the second ear plate, and the positioning section of each vertical bar is inserted into the positioning hole.

[0019] In the above technical solution, the positioning post can form cross-shaped or triangular ribs based on multiple intersecting vertical ribs. Furthermore, the width of the vertical ribs varies to create a wider support section and a narrower positioning section. During assembly, the positioning holes are fitted into the positioning sections of each vertical rib. Compared to the traditional cylindrical structure, this achieves circumferential positioning constraints and reduces the contact area of ​​the positioning hole walls, thus improving the smoothness of the insertion of the positioning sections and holes. The support sections of each vertical rib support the second ear plate, preventing it from being suspended and improving the connection stability between the second ear plate and the speaker cover.

[0020] In some embodiments, the support section of one of the vertical reinforcement bars is integrally connected to the fixed column.

[0021] In the above technical solution, the positioning column and the fixing column can be integrally formed on the speaker cover, so that the support section of one of the vertical ribs and the fixing column can be connected to form an integral structure. This creates a force transmission path between the positioning column and the fixing column, improves the connection strength between the positioning column and the fixing column on the speaker cover, and thus improves the installation stability of the speaker body.

[0022] In some embodiments, the speaker cover has a support ring arranged around the array of sound-permeable holes, the support ring abutting against the outer periphery of the acoustic cavity of the speaker body and a flexible gasket between them.

[0023] In the above technical solution, the support ring can be integrally formed on the speaker cover. The support ring can provide circumferential support for the speaker body, thereby improving the connection stability of the speaker body on the speaker cover. On this basis, the support ring and the outer periphery of the acoustic cavity of the speaker body are buffered by the clamping of flexible gaskets, which prevents the acoustic cavity vibration of the speaker body from being transmitted to the speaker cover. At the same time, it can also ensure that all the sound emitted by the speaker body is transmitted into the vehicle through the sound-permeable hole array, thereby preventing sound leakage and helping to improve the sound quality.

[0024] Secondly, embodiments of this application also provide a vehicle including the aforementioned speaker mounting structure.

[0025] The beneficial effect of the vehicle provided in this application embodiment is that, compared with the prior art, the above-mentioned speaker mounting structure is adopted. The speaker body is inserted into the speaker cover through the insertion limiting part provided on one side, and at the same time, the positioning connecting part provided on the other side is connected and fixed to the positioning fastening part on the speaker cover by fasteners. Since the insertion direction of the insertion limiting part and the insertion limiting part is parallel to the speaker cover, and the insertion fixing direction of the positioning connecting part and the positioning fastening part is perpendicular to the speaker cover, the speaker body can be constrained in any direction in space. Thus, the speaker body can be reliably fixed to the speaker with only one fastener. Compared with the traditional mounting structure that requires multiple screws for fastening, it not only saves assembly time and helps to shorten the process cycle, thereby improving assembly efficiency, but also reduces the risk of fastener falling off and the dependence on installation operation space, thereby helping to optimize the spatial layout of the overall structure.

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the terms "height," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a few" means two or more, unless otherwise explicitly specified.

[0032] It should be explained that the orientation or positional relationship indicated by "front", "rear", "inner", "outer", "upper", and "lower" in the embodiments of this application are based on the orientation of the vehicle itself. Among them, the front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "upper", the bottom of the vehicle represents "lower", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the driver's cab.

[0033] It should be noted that in the prior art, the main installation locations for speakers are the dashboard trim panel and the inner door panel. Among them, the midrange speaker is usually arranged on the inner door panel. The following embodiments are all illustrated using the installation of the midrange speaker as an example. That is, the interior trim panel mentioned in the following embodiments can be understood as the inner door panel. However, it should be emphasized that the speaker mounting structure of this application is also applicable to the installation arrangement of speakers on the dashboard trim panel.

[0034] Current speaker mounting technology primarily uses multiple screws arranged in a circular pattern for fastening, while some vehicle models also employ plug-in positioning structures to complement the screw fastening. The current mounting method utilizes a large number of screws, requiring ample space throughout the entire speaker mounting area for screw assembly. This is extremely disadvantageous for optimal space optimization. Furthermore, the large number of screws not only increases assembly time and the likelihood of screws falling out during assembly, but also raises the probability of screws loosening and falling off later. Therefore, optimizing and improving existing speaker mounting solutions is essential.

[0035] Please refer to the following: Figures 1 to 6 The speaker mounting structure provided in this application will now be described. The speaker mounting structure includes a speaker cover 10 and a speaker body 20. The speaker cover 10 is disposed on a vehicle interior panel, and a sound-permeable hole array 100 is provided in the middle region of the speaker cover 10. A socket limiting part 101 and a positioning fastening part 102 are respectively provided on both sides of the sound-permeable hole array 100. The speaker body 20 is pressed against the speaker cover 10 corresponding to the sound-permeable hole array 100. An insertion limiting part 201 and a positioning connecting part 202 are respectively provided on both sides of the speaker body 20. The socket limiting part 101 and the insertion limiting part 201 are inserted and engaged in a direction parallel to the speaker cover 10, and the positioning fastening part 102 and the positioning connecting part 202 are inserted and engaged in a direction perpendicular to the speaker cover 10 and connected and fixed by fasteners 30.

[0036] It should be understood that in this embodiment, the insertion direction of the socket limiting part 101 and the insertion limiting part 201 is parallel to the speaker cover 10. Therefore, limiting constraints can be formed in both the direction perpendicular to the speaker cover 10 and the direction parallel to the speaker cover 10 and perpendicular to the insertion direction. The positioning fastening part 102 and the positioning connecting part 202 can form a plug-in fit in the direction perpendicular to the speaker cover 10, and at the same time, they can cooperate with the fastener 30 to achieve fastening constraints in the insertion direction. Therefore, not only can the positioning connecting part 202 and the positioning fastening part 102 be fixed in any direction in space, but the degree of freedom of the insertion limiting part 201 and the socket limiting part 101 in the insertion direction can also be constrained, so that both sides of the speaker body 20 can be reliably fixed, and only one fastener 30 is needed.

[0037] Compared with the prior art, the speaker mounting structure provided in this application has a speaker cover 10 set on the interior panel of the vehicle, which serves as both a decorative surface and a mounting base for the speaker body 20. The sound emitted from the acoustic cavity of the speaker body 20 passes through the sound-transmitting hole array 100 set on the speaker cover 10 and enters the vehicle, thereby providing clear sound effects for the driver and passengers. The speaker body 20 is inserted into the speaker cover 10 via the insertion limiting part 201 on one side and the socket limiting part 101 on the speaker cover 10. At the same time, the positioning connecting part 202 on the other side is connected and fixed to the positioning fastening part 102 on the speaker cover 10 via fasteners 30. Since the insertion direction of the insertion limiting part 201 and the socket limiting part 101 is parallel to the speaker cover 10, and the insertion and fixing direction of the positioning connecting part 202 and the positioning fastening part 102 is perpendicular to the speaker cover 10, the speaker body 20 can be constrained in any direction in space. Thus, the speaker body 20 can be reliably fixed to the speaker with only one fastener 30. Compared with the traditional installation structure that requires multiple screws for fastening, this not only saves assembly time and helps to shorten the process cycle, thereby improving assembly efficiency, but also reduces the risk of the fastener 30 falling off and the dependence on the installation operation space, thus helping to optimize the spatial layout of the overall structure.

[0038] It should be noted that the speaker cover 10 can be aligned with the mounting holes on the interior trim panel and fixed to the back of the interior trim panel by screws or welding, or it can be integrally formed as part of the interior trim panel. In this embodiment, the speaker cover 10 is preferably made of plastic sheet. Considering that the interior trim panel is usually also made of plastic material, the welding of the speaker cover 10 to the interior trim panel is plastic welding. If the speaker cover 10 is part of the interior trim panel, it can be integrally formed during the processing of the interior trim panel.

[0039] In some embodiments, see Figures 3 to 6The speaker cover 10 has a bent rib 11 on one side of the sound-permeable hole array 100, which serves as a receiving and limiting part 101. The bent rib 11 arches on the surface of the speaker cover 10 to form a socket 111. A first ear plate 21 is formed by extending one side edge of the speaker body 20. The first ear plate 21 is inserted into the socket 111 as an insertion limiting part 201.

[0040] The rib 11 can be welded to the speaker cover 10 later or it can be integrally formed into the speaker cover 10. Structurally, the rib 11 is an inverted U-shape or arc shape that arches upward, so that a socket 111 parallel to the speaker cover 10 can be formed between the rib 11 and the speaker cover 10.

[0041] After the first ear plate 21, which is formed by extending the edge of the speaker body 20, is inserted into the jack 111, it can form a limiting constraint in any direction other than the insertion direction. This, combined with the insertion and engagement relationship between the positioning connection part 202 on the other side of the speaker body 20 and the positioning fastening part 102 on the speaker cover 10, perpendicular to the speaker cover 10, can ensure the stability of the speaker body 20 on the speaker cover 10. The structure is simple, reliable and convenient for assembly.

[0042] For details, please refer to Figure 3 and Figure 4 The first ear plate 21 gradually narrows in its outer extension direction to form a trapezoidal plate, and the insertion hole 111 is a trapezoidal hole adapted to the trapezoidal plate.

[0043] The first ear plate 21 and the socket 111 adopt a trapezoidal mating cross section. This allows the insertion depth of the first ear plate 21 to be limited by the contact between the inclined surface of the trapezoidal plate and the inclined wall of the socket 111 when the first ear plate 21 is inserted into the socket 111. This limits the speaker body 20 in the insertion direction, which not only makes it easy to achieve precise alignment of the positioning connection part 202 and the positioning fastening part 102, saving alignment time and improving assembly efficiency, but also improves the stability of the insertion fit between the first ear plate 21 and the socket 111, thereby improving the connection stability of the speaker body 20.

[0044] For some possible implementations, please refer to [link / reference]. Figure 3 , Figure 5 and Figure 6 The speaker cover 10 is provided with a protruding limiting frame 12, and the interior of the limiting frame 12 forms a clearance space 121 suitable for the first ear plate 21 to extend into. The two ends of the bent rib 11 are respectively connected to the two side walls of the limiting frame 12, and a plug-in port 112 is formed between the bent rib 11 and the side wall of the limiting frame 12 facing the sound transmission hole array 100. The first ear plate 21 is adapted to be inclined to pass through the plug-in port 112 and extend into the clearance space 121, and when it comes into contact with the bent rib 11, it swings out of the clearance space 121 and presses against the limiting frame 12.

[0045] The limiting frame 12 can be welded to the surface of the speaker cover 10 later, or it can be directly integrally formed with the speaker cover 10; the limiting frame 12 can be a rectangular frame, a trapezoidal frame or other shapes, and the limiting frame 12 can be a circumferentially semi-open frame or a circumferentially fully closed frame.

[0046] Considering that the insertion direction of the positioning connection part 202 and the positioning fastening part 102 is perpendicular to the speaker cover 10, the first ear plate 21 cannot be inserted into the socket 111 in a direction parallel to the speaker cover 10. Therefore, the socket 111 needs to have a size greater than the thickness of the first ear plate 21 in a direction perpendicular to the speaker cover 10 so that the first ear plate 21 can be inserted into the socket 111 at an angle. However, this will result in an excessively large mating gap between the first ear plate 21 and the socket 111 in a direction perpendicular to the speaker cover 10, thereby affecting the connection stability of the speaker body 20. In this embodiment, this problem can be avoided by setting a limiting frame 12.

[0047] Specifically, the size of the insertion hole 111 formed by the rib 11 and the limiting frame 12 in the direction perpendicular to the speaker cover 10 matches the thickness of the first ear plate 21, while the insertion port 112 has a size greater than the thickness of the first ear plate 21 due to the misalignment of the sidewalls of the rib 11 and the limiting frame 12 in the insertion plate direction.

[0048] When installing the speaker body 20, the first ear plate 21 is first inserted into the clearance space 121 through the insertion port 112 at an angle. Since the first ear plate 21 is a trapezoidal plate, the part of the first ear plate 21 that passes through the insertion port 112 gradually widens as it is inserted into the insertion port 112. When the first ear plate 21 abuts against the bent rib 11, it means that it is inserted in place. At this time, the speaker body 20 is swung to a state parallel to the speaker cover 10. During this process, the part of the first ear plate 21 that passes through the insertion port 112 moves out of the clearance space 121. 1. It abuts against the arched part of the rib 11, thereby using the rib 11 and the limiting frame 12 to limit the first ear plate 21 in the direction perpendicular to the speaker cover 10. Since the trapezoidal inclined surface of the first ear plate 21 abuts against the rib 11 in the insertion direction to form a limit, the positioning connection part 202 located on the opposite side of the first ear plate 21 can be aligned with the positioning fastener 102, thereby facilitating the subsequent insertion of the positioning connection part 202 and the positioning fastener 102 and the connection of the fastener 30, thus improving the efficiency of the assembly operation.

[0049] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4A second ear plate 22 is formed by extending one side edge of the speaker body 20. The second ear plate 22 is provided with positioning holes 221 and connecting holes 222 at intervals to form a positioning connection part 202. The positioning fastening part 102 includes a positioning post 13 and a fixing post 14. The positioning post 13 is inserted into the positioning hole 221, and the fixing post 14 abuts against the second ear plate 22 and is aligned with the connecting hole 222. The fastener 30 passes through the connecting hole 222 and is screwed into the fixing post 14.

[0050] The second ear plate 22 formed by extending the edge of the speaker body 20 can provide a position for the positioning hole 221 and the connection hole 222. After the insertion limiting part 201 and the socket limiting part 101 are inserted and engaged, the positioning hole 221 is sleeved on the positioning post 13, and the fastener 30 passing through the connection hole 222 is screwed into the fixing post 14 to fix the speaker body 20.

[0051] The insertion and engagement of the positioning post 13 and the positioning hole 221 can form a positioning constraint in any direction parallel to the speaker cover 10. The fastener 30 passing through the connection hole 222 and the screw connection with the fixing post 14 can form a fastening constraint in the direction perpendicular to the speaker cover 10. A single fastener 30 can achieve a reliable connection of the speaker body 20 on the speaker cover 10. The installation method is simple and reliable, which is conducive to optimizing the spatial layout and improving the efficiency of assembly operations.

[0052] like Figure 3 As shown, as a specific structural form of the aforementioned fixing column 14, the fixing column 14 includes a core column 141 and a number of reinforcing ribs 142 distributed circumferentially around the outer periphery of the core column 141. The core column 141 is adapted to pass through the connecting hole 222 and be screwed into the fastener 30. Each reinforcing rib 142 abuts against and is supported on the second ear plate 22.

[0053] The core post 141 and the reinforcing rib 142 can be integrally formed on the speaker cover 10. The core post 141 has a threaded hole in the center and is screwed to the fastener 30 for fixation. The function of the reinforcing rib 142 is to improve the connection strength between the core post 141 and the speaker cover 10, and to provide support for the second ear plate 22. This allows the fastener 30 and the reinforcing rib 142 to work together to clamp the second ear plate 22, preventing the second ear plate 22 from being suspended and subjected to force, which would affect the overall connection structure strength.

[0054] For example, please refer to Figure 3 The positioning post 13 includes multiple vertical ribs distributed in a cross pattern. Each vertical rib includes a support section 131 and a positioning section 132. The support section 131 of each vertical rib abuts against and supports the second ear plate 22, and the positioning section 132 of each vertical rib is inserted into the positioning hole 221.

[0055] The positioning post 13, based on multiple intersecting vertical ribs, can form a cross rib or a triangular rib. Furthermore, based on the variation in the width of the vertical ribs, it forms a wider support section 131 and a narrower positioning section 132. During assembly, the positioning holes 221 are fitted onto the positioning sections 132 of each vertical rib. Compared to the traditional cylindrical structure, this achieves circumferential positioning constraint and reduces the contact area of ​​the hole walls of the positioning holes 221, thereby improving the smoothness of the insertion of the positioning sections 132 and the positioning holes 221. The support sections 131 of each vertical rib support the second ear plate 22, preventing it from being suspended and thus improving the connection stability between the second ear plate 22 and the speaker cover 10.

[0056] Based on the above-mentioned positioning column 13 structure, such as Figure 3 As shown, in this embodiment, the supporting section 131 of one of the vertical reinforcement bars is connected to the fixed column 14 as a whole.

[0057] The positioning post 13 and the fixing post 14 can be integrally formed on the speaker cover 10, so that the support section 131 of one of the vertical ribs and the fixing post 14 can be connected to form an integral structure. This creates a force transmission path between the positioning post 13 and the fixing post 14, improves the connection strength between the positioning post 13 and the fixing post 14 on the speaker cover 10, and thus improves the installation stability of the speaker body 20.

[0058] It should be noted that you should refer to [link / reference]. Figures 4 to 6 In this embodiment, the speaker cover 10 has a support ring 15 surrounding the sound-permeable hole array 100. The support ring 15 abuts against the outer periphery of the acoustic cavity of the speaker body 20 and a flexible gasket 23 is provided between the two.

[0059] The support ring 15 can be integrally formed on the speaker cover 10. The support ring 15 can form a circumferential support for the speaker body 20, thereby improving the connection stability of the speaker body 20 on the speaker cover 10. On this basis, the support ring 15 and the outer periphery of the acoustic cavity of the speaker body 20 are buffered by the flexible gasket 23, which prevents the acoustic cavity vibration of the speaker body 20 from being transmitted to the speaker cover 10. At the same time, it can also ensure that all the sound emitted by the speaker body 20 is transmitted into the vehicle through the sound-permeable hole array 100, thereby preventing sound leakage and helping to improve the sound quality.

[0060] Based on the same inventive concept, combined with Figures 1 to 6 It is understood that this application also provides a vehicle including the above-described speaker mounting structure.

[0061] Compared with the prior art, the vehicle provided in this application adopts the above-mentioned speaker mounting structure. The speaker body 20 is inserted into the speaker cover 10 via the insertion limiting part 201 provided on one side and the socket limiting part 101 on the speaker cover 10. At the same time, the positioning connecting part 202 provided on the other side is connected and fixed to the positioning fastening part 102 on the speaker cover 10 via fasteners 30. Since the insertion direction of the insertion limiting part 201 and the socket limiting part 101 is parallel to the speaker cover 10, and the insertion fixing direction of the positioning connecting part 202 and the positioning fastening part 102 is perpendicular to the speaker cover 10, the speaker body 20 can be constrained in any direction in space. Thus, the speaker body 20 can be reliably fixed on the speaker with only one fastener 30. Compared with the traditional mounting structure that requires multiple screws for fastening, this not only saves assembly time and helps to shorten the process cycle, thereby improving assembly efficiency, but also reduces the risk of the fastener 30 falling off and the dependence on the installation operation space, thus helping to optimize the spatial layout of the overall structure.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
