[0003] However, car subwoofers are prone to resonance with vehicle components such as the rear bumper and charging port during operation, which can cause abnormal noises and affect the user experience. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide a speaker enclosure assembly, a vehicle subwoofer, and a vehicle with better vibration reduction effect.

[0005] To achieve the above objectives, one embodiment of this application provides a speaker enclosure assembly, comprising:

[0006] A housing with an assembly port;

[0007] A vibration damping bushing includes a flexible vibration damping body, the flexible vibration damping body having a connecting part, a vibration damping part, and an installation channel, the vibration damping part being disposed on one side of the connecting part, the installation channel passing through the vibration damping part and the connecting part; the connecting part being located in the assembly opening, and the vibration damping part being located outside the assembly opening.

[0008] In one embodiment, along the axial direction of the mounting channel, the shape of at least a portion of the vibration damping portion gradually tapers away from the connecting portion.

[0009] In one embodiment, the vibration damping part abuts against the housing.

[0010] In one embodiment, the flexible vibration damping body further includes an extension portion, which is disposed on the side of the connecting portion away from the vibration damping portion and located outside the assembly port, and the mounting channel extends through the extension portion.

[0011] In one embodiment, along the axial direction of the mounting channel, at least a portion of the shape of the extension gradually tapers away from the connection portion.

[0012] In one embodiment, the vibration damping part, the connecting part, and the extension part together form an annular groove surrounding the mounting channel, and the portion of the housing located around the assembly opening is interference-fitted with the annular groove.

[0013] In one embodiment, the housing includes an outer shell and support feet disposed on the outer shell, and the assembly port is disposed on the support feet.

[0014] In one embodiment, the support foot includes a support portion having the mounting opening and an annular protrusion disposed on the support portion, the annular protrusion surrounding the periphery of the mounting opening.

[0015] In one embodiment, the support portion is provided with a mounting groove having a bottom wall and a side wall, the assembly opening penetrates through the bottom wall, and the annular protrusion is provided on the bottom wall; the support foot further includes a reinforcing rib provided on the bottom wall, and the reinforcing rib is connected to the annular protrusion and the side wall respectively.

[0016] In one embodiment, there are multiple support feet, some of which are located on one side of the housing and others are located on the opposite side of the housing. Each support foot has a vibration damping bushing at its mounting opening.

[0017] In one embodiment, the damping bushing includes a rigid inner core with a through hole, the rigid inner core being disposed in the mounting channel to support the flexible damping body.

[0018] In one embodiment, the flexible damping body is made of rubber, and the rigid body mode of the rubber is 40Hz-50Hz; and / or, the hardness tolerance of the rubber is ±2°.

[0019] Another embodiment of this application provides a vehicle-mounted subwoofer, including:

[0020] The speaker enclosure assembly described above;

[0021] A loudspeaker, which is disposed within the enclosure.

[0022] Another embodiment of this application provides a vehicle, including:

[0023] Body-in-white with mounting holes;

[0024] In the aforementioned vehicle-mounted subwoofer enclosure, the vibration damping part faces the vehicle body, and the mounting channel communicates with the mounting hole;

[0026] In one embodiment, the vibration damping part is in contact with the body-in-white.

[0027] This application provides a speaker enclosure assembly, a vehicle subwoofer, and a vehicle. The speaker enclosure assembly, by incorporating a vibration-damping bushing with a flexible vibration-damping body, can separate the vehicle's body-in-white from the speaker enclosure assembly's enclosure using the vibration-damping portion of the flexible vibration-damping body. Simultaneously, the vibration-damping portion can absorb the vibration energy generated by the vehicle subwoofer during operation through deformation, thereby effectively preventing the transmission of vibration energy generated by the vehicle subwoofer during operation to the body-in-white. This can reduce or even eliminate the resonance between the vehicle subwoofer and the body-in-white. Therefore, by using the speaker enclosure assembly of this application embodiment, the vehicle subwoofer can achieve a better vibration damping effect. Attached Figure Description

[0034] In the description of the embodiments in this application, it should be noted that the orientation or positional relationship indicated by terms such as "axial direction" is based on the appendix. Figure 4The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to 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 on the embodiments of this application.

[0035] This application provides a vehicle; please refer to [link / reference]. Figure 1 and Figure 4 The vehicle includes a white body 20, a vehicle-mounted subwoofer 10, and a first fastener 30.

[0036] Please see Figure 1 The vehicle subwoofer 10 includes a speaker enclosure assembly 11 and a speaker 12.

[0037] The speaker enclosure assembly 11 includes an enclosure 111 and a damping bushing 112, and the speaker 12 is disposed inside the enclosure 111.

[0038] Please see Figure 4 The housing 111 has an assembly port 111a, which is used to install the vibration damping bushing 112. The number of assembly ports 111a can be one or more, and the number of vibration damping bushings 112 corresponds one-to-one with the number of assembly ports 111a.

[0039] Figure 4 The assembly port 111a shown is a hole closed on all sides. In other embodiments, the assembly port 111a may also be a notch with an opening.

[0040] The vibration damping bushing 112 includes a flexible vibration damping body 1121. The flexible vibration damping body 1121 has a connecting part 1121a, a vibration damping part 1121b, and an installation channel 1121c. The vibration damping part 1121b is disposed on one side of the connecting part 1121a, and the installation channel 1121c passes through the vibration damping part 1121b and the connecting part 1121a.

[0041] The vibration damping bushing 112 is used to perform vibration damping. Specifically, the flexible vibration damping body 1121 is the main structure of the vibration damping bushing 112. The flexible vibration damping body 1121 is mainly made of flexible material that can perform vibration damping. The flexible vibration damping body 1121 can produce a certain elastic deformation under the action of external force. After the external force is removed, the flexible vibration damping body 1121 can return to its original shape.

[0042] The flexible vibration damping body 1121 absorbs vibration energy through deformation, converting kinetic energy into thermal or mechanical energy, thereby reducing vibration.

[0043] For example, the flexible vibration damping body 1121 can be made of one or more of the following materials: rubber (including natural rubber and synthetic rubber, wherein synthetic rubber includes nitrile rubber, butene rubber, silicone rubber and chloroprene rubber, etc.), polyurethane, fluororubber, silicone, damping plastic, etc.

[0044] Preferably, the rigid body mode of the rubber can be 40Hz-50Hz (including endpoint values), for example, the rigid body mode of the rubber can be 40Hz, 42Hz, 45Hz, 50Hz, etc.

[0045] Rigid body modes refer to modes in which all particles of a structure maintain their relative positions in a free state, i.e., without deformation effects. The rigid body modes of rubber are 40Hz-50Hz, which can effectively ensure that the flexible vibration damping body 1121 has suitable stiffness, can withstand large external forces without deformation, and can also effectively absorb impacts and vibrations.

[0046] Preferably, the hardness tolerance of the rubber can be ±2°.

[0047] The hardness tolerance of rubber refers to the maximum allowable deviation between the hardness value of a rubber product and the standard hardness value. Setting the hardness tolerance of rubber to ±2° allows the hardness difference of the flexible vibration damping body 1121 to be controlled within a reasonable range, thereby enabling the flexible vibration damping body 1121 to better absorb and disperse impact forces, and thus achieve a better vibration damping effect.

[0048] Please continue reading. Figure 4 The connecting part 1121a is located in the assembly port 111a, and the vibration damping part 1121b is located outside the assembly port 111a. The vibration damping part 1121b is used to cooperate with the body-in-white 20 to absorb vibration energy and minimize the transmission of vibration energy to the body-in-white 20, thereby playing a role in vibration damping.

[0049] Please see Figure 4 The body-in-white 20 has mounting holes 30a, the damping part 1121b faces the body-in-white 20, and the mounting channel 1121c communicates with the mounting hole 30a. A first fastener 30 passes through the mounting channel 1121c and the mounting hole 30a to securely connect the vehicle subwoofer 10 to the body-in-white 20 via the first fastener 30. In other words, the vehicle subwoofer 10 is connected to the body-in-white 20 via a damping bushing 112.

[0050] Figure 4 The vibration damping part 1121b shown is in contact with the body-in-white 20. In other embodiments, other components, such as gaskets or sponges, may also be sandwiched between the vibration damping part 1121b and the body-in-white 20, so that the vibration damping part 1121b can also be in indirect contact with the body-in-white 20.

[0051] Figure 4 The vehicle shown also includes a second fastener 40, a portion of which protrudes from the mounting channel 1121c and is threadedly connected to the second fastener 40. Exemplarily, the first fastener 30 may be a bolt, and the second fastener 40 may be a nut.

[0052] In other embodiments, the second fastener 40 may not be provided. For example, the first fastener 30 may be a screw or a screw-like structure, and the mounting channel 1121c or mounting hole 30a may be a threaded hole that is threadedly engaged with the first fastener 30.

[0053] By providing a damping bushing 112 with a flexible damping body 1121, the speaker enclosure assembly 11 can use the damping part 1121b of the flexible damping body 1121 to separate the vehicle body 20 from the enclosure 111 of the speaker enclosure assembly 11. At the same time, the damping part 1121b can absorb the vibration energy generated when the vehicle subwoofer 10 is working through deformation, thereby effectively preventing the vibration energy generated when the vehicle subwoofer 10 is working from being transmitted to the body 20, thereby reducing or even eliminating the resonance between the vehicle subwoofer 10 and the body 20. Therefore, by using the speaker enclosure assembly 11 of this application embodiment, the vehicle subwoofer 10 can have a better vibration damping effect.

[0054] It should be noted that the speaker enclosure assembly 11 in this application embodiment is not limited to use in vehicle subwoofer 10. The speaker enclosure assembly 11 can also be used in any other type of vehicle or non-vehicle speaker according to design requirements.

[0055] In one embodiment, please refer to Figure 4 Along the axial direction of the mounting channel 1121c, the shape of at least a portion of the vibration damping part 1121b can gradually shrink away from the connecting part 1121a.

[0056] In other words, the vibration damping part 1121b can adopt a variable cross-section structure with varying cross-sectional area (the cross-sectional area mentioned in this embodiment refers to the area of ​​the cross-section perpendicular to the axial direction of the mounting channel 1121c). The vibration damping part 1121b may only have a portion of...

[0057] The domain can be a variable cross-section structure, or the entire region can be a variable cross-section structure. For the part forming the variable cross-section, the farther away from the connection part 1121a, the smaller the cross-sectional area of ​​the damping part 1121b. This type of damping part 1121b can better disperse or absorb the vibration energy generated by the vehicle subwoofer 10 during operation, thereby further improving the vibration damping effect.

[0058] In one embodiment, please refer to Figure 4The damping part 1121b can abut against the enclosure 111. That is, the outer contour of the end face of the damping part 1121b near the connecting part 1121a is larger than the outer contour of the cross-section of the mounting channel 1121c, preventing the damping part 1121b from entering the mounting channel 1121c under external force. During the operation of the vehicle subwoofer 10, the damping part 1121b can undergo a certain elastic deformation under the pressure of the enclosure 111 and the body 20, thus achieving better vibration damping.

[0059] In one embodiment, please refer to Figure 3 and Figure 4 The flexible vibration damping body 1121 may also be provided with an extension 1121d. The extension 1121d is provided on the side of the connecting part 1121a away from the vibration damping part 1121b and is located outside the assembly port 111a. The installation channel 1121c passes through the extension 1121d. That is to say, a part of the structure of the flexible vibration damping body 1121 can extend from the side of the assembly port 111a away from the vibration damping part 1121b to the outside of the assembly port 111a.

[0060] Since the first fastener 30 passes through the mounting channel 1121c, the extension 1121d is provided to better separate the first fastener 30 from the support foot 1112, so as to minimize the resonance between the first fastener 30 and the housing 111.

[0061] Please continue reading. Figure 3 and Figure 4 Along the axial direction of the mounting channel 1121c, at least a portion of the extension 1121d can gradually taper away from the connecting portion 1121a. In other words, the extension 1121d can also employ a variable cross-section structure. This means that only a portion of the extension 1121d can have a variable cross-section, or the entire extension 1121d can have a variable cross-section. For the variable cross-section portion, the farther away from the connecting portion 1121a, the smaller the cross-sectional area of ​​the extension 1121d. This type of extension 1121d can also disperse or absorb vibration energy during the operation of the vehicle-mounted subwoofer 10, thereby further improving the vibration reduction effect.

[0062] Please continue reading. Figure 4The damping part 1121b, the connecting part 1121a, and the extension part 1121d can jointly form an annular groove 1121e surrounding the mounting channel 1121c. The part of the housing 111 located around the assembly port 111a can be interference-fitted with the annular groove 1121e, which is equivalent to the damping part 1121b and the extension part 1121d both abutting against the housing 111. This can improve the reliability of the flexible damping body 1121 installed on the housing 111, and also enable the damping part 1121b and the extension part 1121d to play a better damping role.

[0063] In one embodiment, please refer to Figure 1 and Figure 2 The enclosure 111 can be provided with an outer shell 1111 and a support foot 1112. The support foot 1112 is provided on the outer shell 1111, and the mounting port 111a is provided on the support foot 1112. The support foot 1112 can have one mounting port 111a or multiple mounting ports 111a. That is to say, the vibration damping bushing 112 can be provided on the support foot 1112, thereby facilitating the installation of the vehicle subwoofer 10.

[0064] For example, please refer to Figure 2 The support foot 1112 may include a support portion 1112a having a mounting opening 111a and an annular protrusion 1112b provided on the support portion 1112a. The annular protrusion 1112b surrounds the periphery of the mounting opening 111a to strengthen the part of the support foot 1112 located on the periphery of the mounting opening 111a, thereby improving the reliability of the connection between the vibration damping bushing 112 and the support foot 1112.

[0065] Please continue reading. Figure 2 The support portion 1112a can be provided with a mounting groove 1112a1 having a bottom wall 1112a2 and a side wall 1112a3. The assembly opening 111a penetrates the bottom wall 1112a2, and an annular protrusion 1112b is provided on the bottom wall 1112a2. The support foot 1112 can also be provided with reinforcing ribs 1112c. The number of reinforcing ribs 1112c can be one or more. The reinforcing ribs 1112c are provided on the bottom wall 1112a2 and are respectively connected to the annular protrusion 1112b and the side wall 1112a3. The reinforcing ribs 1112c can further strengthen the support portion 1112a and the annular protrusion 1112b to better prevent the support foot 1112 from deforming.

[0066] The housing 111 may be provided with multiple support feet 1112. For example, please refer to [reference needed]. Figure 1Some support feet 1112 can be located on one side of the outer casing 1111, and other support feet 1112 can be located on the opposite side of the outer casing 1111. Each support foot 1112 has a vibration-damping bushing 112 at its mounting opening 111a. In other words, at least one support foot 1112 can be located on each of the opposite sides of the outer casing 1111. For example, Figure 1 The speaker enclosure assembly 11 shown has two support feet 1112 on each of the opposite sides of the outer shell 1111.

[0067] One set of support feet 1112 is located on one side of the housing 1111, and the other set of support feet 1112 is located on the opposite side of the housing 1111. This can improve the reliability of the installation of the car subwoofer 10 and also improve the vibration reduction effect of the car subwoofer 10.

[0068] In one embodiment, please refer to Figures 2 to 4 The vibration damping bushing 112 may be provided with a rigid inner core 1122 having a through hole 1122a. The rigid inner core 1122 is provided in the mounting channel 1121c to support the flexible vibration damping body 1121.

[0069] The rigid inner core 1122 is mainly made of rigid materials, such as aluminum or other metals.

[0070] The rigid inner core 1122 does not contact the body-in-white 20.

[0071] For the vibration damping bushing 112 with a rigid inner core 1122, the first fastener 30 is actually inserted through the through hole 1122a.

[0072] Since the flexible damping body 1121 is mainly made of relatively soft flexible material, setting a rigid inner core 1122 can improve the structural strength of the damping bushing 112 without affecting the damping effect of the flexible damping body 1121.

[0073] In some embodiments, the vibration damping bushing 112 may not have a rigid inner core 1122, that is, the first fastener 30 may be directly inserted into the mounting channel 1121c.
