[0032] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0033] In the present application, the drawings are not necessarily drawn to scale, and local features can be enlarged or reduced to more clearly show the details of the local features.

[0034] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the present application is for the purpose of describing the particular embodiments only and is not intended to limit the scope of the present application. The term "and / or" used in the present application includes any and all combinations of one or more of the associated listed items. The singular forms "a", "an" and "the" used in the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0035] In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified. In the description of the present application, the meaning of "several" is one or more, unless otherwise explicitly specified.

[0036] In the description of the present application, the terms "thickness", "width", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of the simplified description of the present application, and do not indicate that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, i.e. cannot be understood as limiting the present application.

[0037] In the description of the present application, unless otherwise explicitly defined, the terms "mounting", "connection", "connection", "fixing", "setting" and the like should be understood broadly. For example, "connection" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In the description of the present application, unless otherwise explicitly defined, the first feature is "on", "over", "above" and "on top of", "under", "below", "under" or "under" the second feature can be the first feature and the second feature directly contact, or the first feature and the second feature indirectly contact through an intermediate medium. Moreover, the first feature is "over", "above" and "on top of" the second feature can be the first feature directly above or obliquely above the second feature, or just means that the horizontal height of the first feature is higher than the horizontal height of the second feature. The first feature is "under", "below" and "under" the second feature can be the first feature directly below or obliquely below the second feature, or just means that the horizontal height of the first feature is less than the horizontal height of the second feature.

[0039] As the sales of vehicles such as new energy vehicles gradually rise, the vehicle market gradually evolves into a buyer's market, and how to meet the user's experience and quality demand for the whole vehicle becomes more and more important. In order to improve the sound quality and sound field effect of the vehicle, dozens of loudspeakers are added in the vehicle.

[0040] In the related art, the loudspeakers and the hand tools in the vehicle are positioned and installed by a plurality of (for example, two or more) hole pins and a plurality of (for example, three or more) bolts. When assembling the loudspeakers and the hand tools, the loudspeakers need to be manually positioned on the hand tools by the hole pins first. Then the corresponding electric tool gun is used to tighten the bolts. In the production stage, it generally takes about 10 seconds from taking the bolt to tightening it on the loudspeaker. If the tightening time of the bolt for completely fixing the loudspeaker and the hand tool is at least 30 seconds. The installation method of the loudspeaker and the hand tool consumes time and has low assembly efficiency; in addition, there are dozens of loudspeakers in the whole vehicle, which leads to extremely low production flow efficiency in the vehicle assembly process. In order to make up for this low efficiency production, the production workshop has to increase the workstations and personnel, resulting in increased production cost. Moreover, at the beginning of the design of the vehicle, the design cost of the bolts matched with the loudspeakers and the hand tools also needs to be additionally increased, causing the design cost to increase.

[0041] In addition, for the above-mentioned bolt connection method, due to the influence of the plastic hand tool, the torque of the bolt cannot reach the design value in the road test and after-sales maintenance of the vehicle, or the torque of the bolt decays after the vehicle is used for a period of time, resulting in some bolts loosening during driving, and further causing the problem of abnormal noise of the vehicle caused by road excitation in some bad road conditions.

[0042] To solve at least one of the above technical problems, the present application provides a vehicle, a loudspeaker assembly and a mounting bracket. The mounting bracket of the present application is used for mounting a loudspeaker. The mounting bracket has a clamping hole, and an inner wall surface of the clamping hole has an abutting surface. A clamping protrusion of the loudspeaker can be located in the clamping hole and abut against the abutting surface, thereby achieving clamping between the loudspeaker and the mounting bracket, which is conducive to improving the assembly efficiency between the loudspeaker and the mounting bracket, reducing the production cost and design cost, and avoiding the bolt loosening problem between the loudspeaker and the mounting bracket in the related art, thereby avoiding the abnormal sound problem of the vehicle. In addition, the abutting surface can guide the clamping protrusion to smoothly enter or exit the clamping hole during the assembly or disassembly of the loudspeaker, thereby further improving the disassembly and assembly efficiency between the loudspeaker and the mounting bracket.

[0043] The specific structure of the vehicle of the present application will be described in detail below with reference to the accompanying drawings.

[0044] The present application provides a vehicle. The vehicle includes but is not limited to a new energy vehicle, a fuel vehicle, and a hybrid vehicle. In addition, the vehicle includes but is not limited to a family car, a public vehicle, etc.

[0045] Please refer to Figure 1 and Figure 2 The vehicle 100 includes a vehicle body 20, a vehicle door 60, and a loudspeaker assembly 10.

[0046] The vehicle body 20 has a door opening. The vehicle door 60 can be installed at the door opening for opening or closing the door opening. When the vehicle door 60 opens the door opening, it can be convenient for a user to enter the vehicle body 20 or to get out of the vehicle body 20.

[0047] Specifically, the vehicle door 60 is hinged to the vehicle body 20. In this way, through the hinged connection between the vehicle door 60 and the vehicle body 20, the vehicle door 60 can be conveniently opened or closed to open or close the door opening. In other embodiments, the vehicle door 60 and the vehicle body 20 can also be slidingly connected.

[0048] The vehicle body 20 includes a vehicle body (not shown in the figure) and an interior trim panel (not shown in the figure). The interior trim panel is fixed to the inner surface of the vehicle body and can play a role of decorating the interior of the vehicle 100. The interior trim panel can include but is not limited to an A-pillar interior trim panel, a B-pillar interior trim panel, and a C-pillar interior trim panel.

[0049] The loudspeaker assembly 10 is fixed to the vehicle body. Specifically, the loudspeaker assembly 10 can be fixed to the interior trim panel.

[0050] The loudspeaker assembly 10 can be one or multiple. Multiple loudspeaker assemblies 10 are distributed at different positions of the vehicle body 20.

[0051] Please refer toFigure 2 and Figure 3 The loudspeaker assembly 10 can include a loudspeaker 2 and a mounting bracket 1.

[0052] The loudspeaker 2, also referred to as a "speaker", can play audio.

[0053] In one loudspeaker assembly 10, the loudspeaker 2 can be one or more.

[0054] Please refer to Figure 4 In some embodiments, the loudspeaker 2 includes a housing 21, a diaphragm 22, a voice coil 23, and a magnetic circuit system 24.

[0055] The housing 21 serves as a "support skeleton" of the loudspeaker 2, for supporting the diaphragm 22 and fixing the magnetic circuit system 24. The material of the housing 21 includes but is not limited to metal, plastic, and a combination of the two.

[0056] The diaphragm 22 has two sides in the thickness direction, which are a front cavity K1 and a back cavity K2, respectively.

[0057] The diaphragm 22 is fixed to the housing 21. The inner surface of the diaphragm 22 and the inner surface of the housing 21 enclose the back cavity K2 of the loudspeaker 2. The connection mode of the diaphragm 22 and the housing 21 includes but is not limited to gluing, clamping, welding, or screwing.

[0058] The voice coil 23 is located inside the housing 21 and on the side facing the inner surface of the diaphragm 22. The voice coil 23 is connected to the inner surface of the diaphragm 22. The connection mode of the voice coil 23 and the diaphragm 22 includes but is not limited to gluing, clamping, welding, or screwing.

[0059] The magnetic circuit system 24 is installed inside the housing 21 and on the side facing the inner surface of the diaphragm 22. The magnetic circuit system 24 has an annular magnetic gap H. The part of the voice coil 23 away from the diaphragm 22 can extend into the magnetic gap H. It can be understood that in other embodiments, when the voice coil 23 is a planar voice coil, the voice coil 23 can also not extend into the above-mentioned magnetic gap H. The planar voice coil can be manufactured by winding or printing a circuit.

[0060] After the voice coil 23 is powered, an induced magnetic field can be generated. The magnetic circuit system 24 can respond to the induced magnetic field and exert a driving force on the voice coil 23. The voice coil 23 is driven by the magnetic force of the magnetic circuit system 24 to displace, thereby driving the diaphragm 22 to vibrate.

[0061] The vibration of the diaphragm 22 can push the air in the front cavity K1 to vibrate and form a sound wave, which is transmitted to the outside of the loudspeaker 2 for the user to receive the sound wave.

[0062] Please continue to refer to Figure 4 and Figure 5In some embodiments, the speaker 2 is provided with a clamping protrusion 211. Specifically, the clamping protrusion 211 is arranged on the outer circumferential surface of the housing 21.

[0063] For example, the clamping protrusion 211 and the housing 21 can be integrally formed. In this way, the connection strength between the clamping protrusion 211 and the housing 21 can be improved, the processing technology can be simplified, and the manufacturing cost can be reduced. Alternatively, the clamping protrusion 211 and the housing 21 can be connected by means of gluing, welding, clamping, or bolt connection.

[0064] Please refer to Figure 4 and Figure 6 The mounting bracket 1 comprises a body 11 and a sleeve portion 12.

[0065] The body 11 can be in the form of a plate. For example, the body 11 can be in the form of a flat plate, a curved plate, or a combination of the two. The material of the body 11 includes but is not limited to metal or plastic.

[0066] The body 11 is provided with a sound hole 15 that penetrates the body 11. The sound hole 15 is in communication with the front cavity K1 described above, and the sound waves generated by the vibration of the front cavity K1 can be transmitted through the sound hole 15.

[0067] The shape of the sound hole 15 includes but is not limited to a rectangle, a circle, an ellipse, or a special shape.

[0068] The body 11 can be fixed to an interior trim panel.

[0069] For example, the body 11 and the interior trim panel are two independently formed structural members, and the body 11 can be fixed to the interior trim panel by means of welding, screw connection, clamping, or gluing.

[0070] When the body 11 and the interior trim panel are two independently formed structural members, the body 11 can be arranged on the side of the interior trim panel facing the vehicle body, and the interior trim panel can have an opening corresponding to the sound hole 15 at this time.

[0071] Alternatively, the body 11 and the interior trim panel can be integrally formed, that is, the body 11 and the interior trim panel are a monolithic structure.

[0072] The shape of the sleeve portion 12 includes but is not limited to a circular ring, a square ring, or a special-shaped ring. The material of the sleeve portion 12 includes but is not limited to metal or plastic.

[0073] Please refer to Figure 4 and Figure 6 The sleeve portion 12 has opposite insertion end 121 and fixing end 122 along its axial direction. Among them, Figure 4 and Figure 6 The O1 line is the axis of the sleeve portion 12, and the extension direction of the O1 line is the axial direction of the sleeve portion 12.

[0074] The fixed end 122 is fixed to the body 11. Exemplarily, the sleeve part 12 and the body 11 can be integrally formed. In this way, the connection strength between the sleeve part 12 and the body 11 can be improved, the processing technology can be simplified, and the manufacturing cost can be reduced. Exemplarily, the sleeve part 12 and the body 11 can also be connected by means of gluing, welding, clamping, or bolt connection.

[0075] The sleeve part 12 and the body 11 enclose an accommodation space Q. In combination Figure 2 The accommodation space can be used to accommodate the loudspeaker 2. Specifically, the loudspeaker 2 can enter the accommodation space Q from the insertion end 121.

[0076] The sleeve part 12 surrounds the sound hole 15, and the aforementioned front cavity K1 can be located between the diaphragm 22 and the sound hole 15, so as to facilitate the communication between the front cavity K1 and the sound hole 15.

[0077] The sleeve part 12 has a clamping hole 123 on the inner circumferential surface thereof. The clamping hole 123 can be a blind hole recessed from the inner circumferential surface of the sleeve part 12 to the outer circumferential surface of the sleeve part 12, or can be a through hole penetrating the circumferential wall of the sleeve part 12.

[0078] The shape of the clamping hole 123 includes but is not limited to a rectangle, a circle, an ellipse, or a special shape.

[0079] A side wall surface of the clamping hole 123 along the axial direction of the sleeve part 12 and close to the insertion end 121 is an abutting surface 1231. In the direction from the insertion end 121 to the fixed end 122, the abutting surface 1231 extends obliquely away from the axis O1 of the sleeve part 12.

[0080] In this embodiment, when the loudspeaker 2 moves into the accommodation space Q from the insertion end 121 to the fixed end 122, the clamping protrusion 211 on the loudspeaker 2 can gradually extend into the clamping hole 123 until it abuts against the abutting surface 1231, thereby achieving the clamping connection between the loudspeaker 2 and the mounting bracket 1 without using bolt connection, which is beneficial to improve the assembly efficiency between the loudspeaker 2 and the mounting bracket 1, reduce the production cost and design cost, and avoid the bolt loosening problem between the loudspeaker 2 and the mounting bracket 1 in the related art, thereby avoiding the abnormal sound problem of the vehicle 100. Moreover, the abutting surface 1231 can guide the clamping protrusion 211 to enter the clamping hole 123 during the assembly of the loudspeaker 2, and can guide the clamping protrusion 211 to exit the clamping hole 123 during the disassembly of the loudspeaker 2, thereby further improving the disassembly efficiency between the loudspeaker 2 and the mounting bracket 1.

[0081] Exemplarily, the abutting surface 1231 includes but is not limited to a plane, a curved surface, and a combination of the two.

[0082] Exemplarily, the plurality of clamping holes 123 are arranged at intervals in the circumferential direction of the sleeve portion 12. Similarly, the plurality of clamping protrusions 211 of the loudspeaker 2 are also arranged at intervals in the circumferential direction of the loudspeaker 2. In this way, the reliability of the clamping of the mounting bracket 1 and the loudspeaker 2 can be improved.

[0083] In the specific example shown in Figure 6 and Figure 7 , the plurality of clamping holes 123 are three. In other examples, the plurality of clamping holes 123 can also be two, four, five or six.

[0084] Exemplarily, the plurality of clamping holes 123 are arranged at intervals in the circumferential direction of the sleeve portion 12. Similarly, the plurality of clamping protrusions 211 of the loudspeaker 2 are also arranged at intervals in the circumferential direction of the loudspeaker 2. In this way, the reliability of the clamping of the mounting bracket 1 and the loudspeaker 2 can be improved.

[0085] In some embodiments of the present application, please continue to refer to Figure 6 and Figure 7 , the inner circumferential surface of the sleeve portion 12 is provided with a plurality of abutting protrusions 124. The plurality of abutting protrusions 124 are arranged at intervals with the clamping holes 123. The abutting protrusions 124 protrude from the inner circumferential surface of the sleeve portion 12.

[0086] The side surface of the abutting protrusion 124 facing the axis O1 of the sleeve portion 12 is an abutting surface 1241. The abutting surface 1241 is used to abut and cooperate with the outer circumferential surface of the loudspeaker 2. In this way, the abutment of the plurality of abutting protrusions 124 and the outer circumferential surface of the loudspeaker 2 can further limit the loudspeaker 2 in the circumferential and axial directions of the sleeve portion 12, improving the clamping reliability of the loudspeaker 2 and the mounting bracket 1.

[0087] Exemplarily, the plurality of abutting protrusions 124 are arranged at intervals in the circumferential direction of the sleeve portion 12. In this way, the abutment of the plurality of abutting protrusions 124 and the outer circumferential surface of the loudspeaker 2 can further limit the loudspeaker 2 in the circumferential and axial directions of the sleeve portion 12, improving the clamping reliability of the loudspeaker 2 and the mounting bracket 1.

[0088] Exemplarily, the plurality of abutting protrusions 124 are arranged at intervals in the circumferential direction of the sleeve portion 12. In this way, the abutment of the plurality of abutting protrusions 124 and the outer circumferential surface of the loudspeaker 2 can further limit the loudspeaker 2 in the circumferential and axial directions of the sleeve portion 12, improving the clamping reliability of the loudspeaker 2 and the mounting bracket 1. Of course, in other embodiments, the plurality of abutting protrusions 124 are arranged at unequal intervals in the circumferential direction of the sleeve portion 12.

[0089] Exemplarily, the stop protrusion 124 and the sleeve portion 12 can be integrally formed. In this way, the connection strength between the stop protrusion 124 and the sleeve portion 12 can be improved, the processing technology can be simplified, and the manufacturing cost can be reduced. Exemplarily, the stop protrusion 124 and the sleeve portion 12 can also be connected by means of gluing, welding, clamping, or bolt connection.

[0090] Exemplarily, please continue to refer to Figure 6 , a side wall surface of the stop protrusion 124 along the axial direction of the sleeve portion 12 and close to the insertion end 121 is a guide surface 1242. The guide surface 1242 is connected with the stop surface 1241. In the direction from the insertion end 121 to the fixed end 122, the guide surface 1242 extends obliquely towards the direction close to the axis O1 of the sleeve portion 12. In this way, the guide surface 1242 can play a role of avoiding and guiding the movement of the loudspeaker 2 from the insertion end 121 to the fixed end 122, so as to facilitate the abutment between the stop surface 1241 and the outer circumferential surface of the loudspeaker 2.

[0091] Of course, it can be understood that, in other embodiments, the side wall surface of the stop protrusion 124 along the axial direction of the sleeve portion 12 and close to the insertion end 121 can also not be the guide surface 1242, for example, the side surface is arranged perpendicularly to the stop surface 1241.

[0092] In some embodiments of the present application, please continue to refer to Figure 6 , the circumferential wall of the sleeve portion 12 has a deformation hole 126 penetrating through the circumferential wall of the sleeve portion 12. The deformation hole 126 extends to the insertion end 121. At least one side of the clamping hole 123 along the circumferential direction of the sleeve portion 12 is arranged with the deformation hole 126. In this way, the arrangement of the deformation hole 126 can facilitate the deformation of the part of the circumferential wall of the sleeve portion 12 provided with the clamping hole 123 in the direction away from the axis O1 of the sleeve portion 12 during the disassembly and assembly of the loudspeaker 2, thereby facilitating the smooth assembly of the loudspeaker 2.

[0093] Exemplarily, the deformation hole 126 is in a strip shape along the axial direction of the sleeve portion 12.

[0094] Exemplarily, the width dimension of the deformation hole 126 is less than or equal to 5 mm. For example, the width dimension of the deformation hole 126 is 1 mm, 2 mm, 3 mm, or 4 mm.

[0095] Exemplarily, the end of the deformation hole 126 away from the insertion end 121 is located on the side of the abutment surface 1231 away from the insertion end 121. In this way, the deformation of the part of the circumferential wall of the sleeve portion 12 provided with the clamping hole 123 in the direction away from the axis O1 of the sleeve portion 12 during the disassembly and assembly of the loudspeaker 2 can be more facilitated, thereby further facilitating the smooth assembly of the loudspeaker 2.

[0096] Exemplarily, the two sides of the clamping hole 123 along the circumference of the sleeve part 12 are arranged with deformation holes 126.

[0097] Exemplarily, when the clamping holes 123 are multiple, the two sides of at least one clamping hole 123 along the circumference of the sleeve part 12 are arranged with deformation holes 126, and one side of at least one clamping hole 123 along the circumference of the sleeve part 12 is arranged with a deformation hole 126. For example, the clamping holes 123 are three, the two sides of two clamping holes 123 along the circumference of the sleeve part 12 are arranged with deformation holes 126, and one side of one clamping hole 123 along the circumference of the sleeve part 12 is arranged with a deformation hole 126.

[0098] Exemplarily, please continue to refer to Figure 6 and Figure 7 , the inner circumferential surface of the sleeve part 12 has a guide surface 127. The guide surface 127 is connected between the abutting surface 1231 and the insertion end 121. In the direction from the insertion end 121 to the fixed end 122, the guide surface 127 extends obliquely towards the direction close to the axis O1 of the sleeve part 12. In this way, in the process of installing the loudspeaker 2 and the mounting bracket 1, the guide surface 127 can be first roughly aligned with the clamping protrusion 211 in the axial direction of the sleeve part 12, and then the loudspeaker 2 is moved from the insertion end 121 to the fixed end 122 to accommodate the loudspeaker 2 in the accommodation space Q. In this way, the arrangement of the guide surface 127 can on the one hand play a role of rough positioning for the installation between the loudspeaker 2 and the mounting bracket 1, which is beneficial to improve the assembly efficiency; on the other hand, it can also play a role of avoiding and guiding the clamping protrusion 211 during the movement of the loudspeaker 2, so as to facilitate the smooth cooperation of the clamping protrusion 211 and the clamping hole 123.

[0099] Exemplarily, the guide surface 127 includes but is not limited to a plane, a curved surface, and a combination of the two.

[0100] In some embodiments of the present application, please continue to refer to Figure 6 , Figure 7 , and in combination with Figure 4 , the mounting bracket 1 further comprises a support rib 13. The support rib 13 is located on the inner circumferential side of the sleeve part 12 and is fixed to the body 11. The surface of the support rib 13 away from the body 11 is a support surface 131. The surface of the shell 21 facing the body 11 has a matching surface 213. In this way, in the axial direction of the sleeve part 12, the support surface 131 is roughly opposite to the abutting surface 1231, and when the clamping protrusion 211 of the loudspeaker 2 is clamped into the clamping hole 123 and abuts against the abutting surface 1231, the matching surface 213 can abut against the support surface 131, so that the abutting surface 1231 and the support surface 131 can be used to limit the loudspeaker 2 in the axial direction of the sleeve part 12, preventing the loudspeaker 2 from exiting from the accommodation space Q.

[0101] Exemplarily, the support rib 13 and the body 11 can be integrally formed. In this way, the connection strength between the support rib 13 and the body 11 is improved, the processing technology is simplified, and the manufacturing cost is reduced. Exemplarily, the support rib 13 and the body 11 can also be connected by means of gluing, welding, clamping or bolt connection.

[0102] Exemplarily, please continue to refer to Figure 6 and Figure 7 , the support rib 13 is annular and extends along the circumference of the sleeve portion. In this way, the support surface 131 is arranged in an annular shape, so that the support reliability of the loudspeaker 2 can be improved by using the annular support surface 131.

[0103] On this basis, exemplarily, the support rib 13 is coaxially arranged with the sleeve portion 12. In this way, the support reliability of the loudspeaker 2 by the support rib 13 is further improved.

[0104] The support rib 13 surrounds the sound hole 15, and the support rib 13 and the diaphragm 22 jointly enclose the above-mentioned front cavity K1. In this way, the structure is simple and compact.

[0105] Of course, it can be understood that in other embodiments, the mounting bracket 1 can also not be provided with the support rib 13, and the above-mentioned support surface 131 can be formed on the body 11.

[0106] Of course, the configuration form of the front cavity K1 is not limited thereto, and in other embodiments, the front cavity K1 can also be enclosed by the outer surface of the diaphragm 22 and the above-mentioned outer shell 21 of the loudspeaker 2, as long as the front cavity K1 is communicated with the sound hole 15.

[0107] In addition, the present application is not limited thereto, and in other embodiments, the body 11 can also not be provided with the sound hole 15.

[0108] In some embodiments of the present application, please continue to refer to Figure 5 , Figure 6 , Figure 7 , and in combination with Figure 2 , the insertion end 121 has an error-proof gap 125. The outer shell 21 is provided with an error-proof protrusion 212. The error-proof protrusion 212 is located in the error-proof gap 125. In this way, during the process of installing the loudspeaker 2 and the mounting bracket 1, the error-proof protrusion 212 can be aligned with the error-proof gap 125 first, and then the loudspeaker 2 is moved from the insertion end 121 to the fixed end 122 to accommodate the loudspeaker 2 in the accommodation space Q, while the error-proof protrusion 212 is located in the error-proof gap 125. In this way, the corresponding matching of the error-proof protrusion 212 and the error-proof gap 125 prevents the loudspeaker 2 from being placed in reverse, and plays a role of rough positioning for the assembly between the loudspeaker 2 and the mounting bracket 1, thereby further improving the assembly efficiency between the loudspeaker 2 and the mounting bracket 1.

[0109] Exemplarily, the error-proof convex portion 212 and the shell 21 can be integrally formed. In this way, the connection strength of the error-proof convex portion 212 and the shell 21 is improved, the processing technology is simplified, and the manufacturing cost is reduced. Exemplarily, the error-proof convex portion 212 and the shell 21 can also be connected by means of gluing, welding, clamping or bolt connection.

[0110] In some embodiments of the present application, please continue to refer to Figure 7 The sound hole 15 is provided with a grille 14. In this way, the grille 14 can be used to strengthen the mounting bracket 1, and the grille 14 can also be used to protect the loudspeaker 2.

[0111] Exemplarily, the grille 14 and the body 11 can be integrally formed. In this way, the connection strength of the grille 14 and the body 11 is improved, the processing technology is simplified, and the manufacturing cost is reduced. Exemplarily, the grille 14 and the body 11 can also be connected by means of gluing, welding, clamping or bolt connection.
