Attractive appearance, exquisite design, and better comfort have become more important and sought after. A sense of luxury, sophistication, and technological advancement have begun to influence the development of various car models.

[0003] Speakers are an essential part of a car; however, the speakers in this technology lack a sense of luxury and technology, which in turn affects the overall sense of sophistication, luxury, and technology in the interior. Utility Model Content

[0004] In view of this, this application provides a speaker assembly that can effectively enhance the sense of luxury, sophistication, and technological sophistication of a vehicle interior. Furthermore, this application also provides a vehicle including the aforementioned speaker assembly.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0017] Optionally, the speaker body includes:

[0018] The speaker frame has the shock-absorbing element provided on one edge near the end of the speaker grille assembly;

[0019] A diaphragm is fixed to the frame, and the surface of the diaphragm facing the speaker grille assembly is the reflective surface.

[0020] Optionally, the diaphragm includes a diaphragm body and a reflective coating, the reflective coating being disposed on the side of the diaphragm body facing the speaker mask assembly.

Obviously, the drawings described below are only embodiments of this application. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] like Figure 1 As shown in the figure, this application discloses a speaker assembly, which includes a speaker body and a speaker grille assembly, wherein:

[0036] The speaker body is the core acoustic component of the speaker assembly, responsible for converting electrical signals into sound energy.

[0037] For example, the loudspeaker body may include a diaphragm 7, a voice coil, a magnetic circuit system, a suspension, and a frame 6. Wherein:

[0038] The speaker frame 6 serves as the mechanical skeleton of the speaker body, used to fix the internal components of the speaker body (including the diaphragm 7 and components that constitute the magnetic circuit system, etc.) and provide rigid support.

[0039] The magnetic circuit system can be set at the center opening of the frame 6 and used to provide a stable magnetic field environment for the vibration of the voice coil, thereby realizing the conversion of electrical energy into mechanical energy.

[0040] The bottom of the voice coil is fixed to the frame 6 by a spider, and the top is connected to the center of the diaphragm 7 to ensure that the voice coil can move axially and transmit vibration to the diaphragm 7.

[0041] The outer edge of the diaphragm 7 is connected to the frame 6 via a suspension edge, and it generates sound waves by vibrating and pushing air.

[0042] Based on the above-mentioned structure of the loudspeaker body, the principle by which the loudspeaker body converts electrical signals into sound energy is as follows: the audio electrical signal is input to the voice coil of the loudspeaker through the wire. After the voice coil is energized, it generates an alternating magnetic field around it. This alternating magnetic field interacts with the static magnetic field of the permanent magnet in the magnetic circuit system to generate a Lorentz force, which in turn drives the voice coil to reciprocate along the axial direction. The reciprocating motion of the voice coil drives the diaphragm 7 to vibrate, which in turn pushes the surrounding air to generate compression waves (i.e., sound waves).

[0043] It should be noted that the above is merely an exemplary description of the structure of the speaker body for the purpose of understanding the speaker body, but the embodiments of this application are not limited thereto. In specific implementation, the speaker body can be any structure capable of converting electrical signals into sound energy.

[0044] The speaker grille assembly is a protective structure for the speaker assembly, and also serves as an acoustic control and industrial design feature.

[0045] like Figure 1 As shown, the speaker mask assembly in this embodiment includes a speaker mask 5 and a mask bracket 4 fixedly connected to the speaker mask 5, wherein:

[0046] The speaker grille bracket 4 is a fixing structure in the speaker grille assembly, which can at least be used to connect the speaker grille 5 and the speaker assembly assembly structure (i.e., the structure for mounting the speaker assembly, exemplarily, the trim and sheet metal parts described below).

[0047] The speaker grille 5 is a layer of covering located on the front of the speaker body in the speaker grille assembly. It is mainly used to protect the speaker body and improve the appearance design.

[0048] Continue as Figure 1 As shown, the mask bracket 4 is provided with a light-emitting element 8 that emits light towards the speaker body. The light-emitting element 8 is an optical module integrated into the speaker system and is used for dynamic visual effects presentation or status indication.

[0049] Regarding the type of light-emitting element 8, it can be adapted to the needs of specific implementation. This application does not impose specific limitations on the embodiments. For example, the light-emitting element 8 can be a light strip and / or a light bead, etc.

[0050] Furthermore, regarding the fixing method between the light-emitting element 8 and the mask bracket 4, in specific implementation, adhesive bonding or screw connection can be used, and this application does not make specific limitations in this regard.

[0051] Continue as Figure 1 As shown, the mask bracket 4 is connected to the speaker body (including but not limited to the mask bracket 4 abutting against the speaker body); and the surface of the speaker body facing the speaker mask 5 includes a reflective surface 701, the light generated by the light-emitting element 8 shines on the reflective surface 701 and is emitted through the speaker mask 5.

[0052] As described above, the speaker assembly in this embodiment of the application is provided with a light-emitting element 8, and the light energy generated by the light-emitting element 8 after being powered on is emitted through the speaker cover 5. This setting, together with the speaker cover 5 which has a certain shape design, can effectively improve the visual impact of the speaker assembly, thereby improving the technological feel of the speaker assembly.

[0053] In addition, the light-emitting element 8 is mounted on the mask bracket 4 and faces the speaker body to emit light. The surface of the speaker body facing the speaker mask 4 includes a reflective surface 701. The light emitted by the light-emitting element shines on the reflective surface 701 and is diffusely reflected by the reflective surface 701 before being emitted through the speaker mask 5. In this configuration, the reflective surface 701 of the speaker body can homogenize the light emitted by the light-emitting element 8, thereby improving the uniformity of light emission from the speaker assembly. This further enhances the premium, luxurious, and technological feel of the speaker assembly.

[0054] In some embodiments, such as Figure 1 As shown, the mask support 4 includes a connecting structure 402 for connecting the speaker assembly assembly structure and a cylindrical structure 401 having a first end and a second end, wherein the first end of the cylindrical structure 401 is connected to the speaker body; the second end of the cylindrical structure 401 has a flange 403 folded toward the inner side of the cylindrical structure 401, which can serve as a reinforcing structure to reduce the probability of the mask support 4 deforming under external force.

[0055] Optionally, in some embodiments, the surface of the flange 403 facing the speaker mask 5 abuts against the inner surface of the speaker mask 5. That is, in this embodiment, the flange 403 can support the speaker mask 5 fixed on the mask bracket 4. In this way, the connection area between the speaker mask 5 and the mask bracket 4 is larger, which helps to improve the connection effect between the speaker mask 5 and the mask bracket 4.

[0056] Continue as Figure 1 As shown, the flange 403 forms a light-shielding groove with the inner wall of the cylindrical structure 401, and the opening of the light-shielding groove faces the reflective surface 701 of the speaker body. The light-emitting element 8 is disposed inside the light-shielding groove.

[0057] In this embodiment, when the light-emitting element 8 is powered on, the light-shielding groove can block the light emitted by the light-emitting element 8, preventing the light emitted by the light-emitting element 8 from being directly emitted through the speaker mask 5. In other words, the light-shielding groove can hide the light-emitting element 8, preventing passengers from seeing the light-emitting element 8 through the speaker mask 5.

[0058] Understandably, compared to direct light, light rays need to travel a longer or more complex path to reach the observation point after being reflected by the reflective surface 701. Since different light rays have different path lengths, the light intensity will be averaged out, thereby reducing local brightness differences. Therefore, in this embodiment, by setting the light-shielding groove, the uniformity of light emission from the speaker assembly can be effectively improved, further enhancing the premium, luxurious, and technological feel of the speaker assembly.

[0059] In some embodiments, such as Figure 1 As shown, the speaker grille 5 includes a first part 502 and a second part 501 arranged around the first part 502: wherein the first part 502 is located at the center of the speaker grille 5, and the first part 502 protrudes from the second part 501 in a direction away from the speaker body; the second part 501 is a recessed structure facing the side of the speaker body, and the second part 501 connects the first part 502 and the grille support.

[0060] As described above, in this embodiment, the first part 502 of the speaker cover 5 is a recessed structure facing the speaker body, while the second part 501 is located in the center of the cover and protrudes outward. The first part 502 and the second part 501 work together to form a three-dimensional visual focal point. This setting greatly enhances the visual impact of the speaker assembly, thereby improving the technological and high-end feel of the speaker assembly.

[0061] Furthermore, in some embodiments, the first part 502 is configured as a solid structure that cannot be exposed to light, and the second part 501 is configured as a perforated structure that can be exposed to light.

[0062] In this embodiment, since the first part 502 and the second part 501 can produce different visual effects, in specific implementations, by designing the shape and / or distribution of the first part 502 (or the second part 501), the design and premium feel of the speaker grille assembly can be improved, thereby enhancing the premium feel of the speaker assembly. For example, the design of the speaker grille assembly can be improved by setting the second part 501 in a plum blossom shape. Alternatively, the design of the speaker grille assembly can be improved by setting a raised pattern on the surface of the second part 501.

[0063] Furthermore, in this embodiment, since the first part 502 can serve as the dark decorative area of ​​the speaker cover 5 (i.e., the part with relatively low brightness and a decorative function), and the second part 501 is arranged around the first part 502, when the light-emitting element 8 is powered on, light is emitted from the first part 502, thereby forming the bright decorative area of ​​the speaker cover 5 (i.e., the part with relatively high brightness and a decorative function). The combination of light and dark (specifically, a bright area that can emit light combined with a dark area with a pattern) gives the speaker cover 5 in this embodiment a better visual effect, thereby enhancing the premium feel of the speaker assembly. In addition, the raised structure produces light and shadow displacement when the viewing angle changes, which, combined with the brightness change of the light-transmitting area, can give the speaker assembly a visual dynamic effect, thereby further enhancing the premium feel of the speaker assembly.

[0064] like Figure 1 As shown, the speaker body includes a shock absorber 3, and the shock absorber 3 is disposed at the position of the speaker body for connecting the mask bracket 4.

[0065] Shock absorber 3 refers to a buffer component that can achieve elastic deformation.

[0066] In practical implementation, the shock absorber 3 can be foam, rubber and / or silicone, etc.

[0067] Furthermore, the shape of the shock absorber 3 can be adapted to the specific implementation as needed, and this application does not impose any specific limitations on it.

[0068] In this embodiment, the damping component 3 serves two purposes. First, it acts as a vibration isolation structure to suppress resonance transmission and reduce resonance noise. Specifically, the speaker body generates mechanical vibrations during operation. The damping component 3 absorbs vibration energy through elastic deformation, preventing the vibration from being directly transmitted to the speaker grille support 4, thus avoiding resonance and resonance noise. Second, it acts as a protective structure to mitigate mechanical impacts and extend the service life of the speaker assembly. Specifically, the speaker grille 5 serves as a protective structure for the speaker assembly. When the speaker grille 5 is impacted, the impact force is transmitted towards the speaker body through the grille support 4. The damping component 3 disperses the impact force, thereby reducing the impact on the speaker body. This design reduces fatigue wear on the screws, welds, and other connecting parts of the speaker body caused by long-term vibration, preventing loosening or breakage, and thus contributing to an increased service life of the speaker assembly.

[0069] For example, in some embodiments, the shock absorber 3 is an annular foam, which is disposed at the position of the speaker body for connecting the mask bracket 4, and the end face of the annular foam abuts against the mask bracket 4.

[0070] In some embodiments, the speaker body includes a frame 6 and a diaphragm 7, wherein:

[0071] The edge of the frame 6 near the speaker grille assembly is provided with a shock-absorbing member 3 for connecting the grille bracket 4. That is, in this embodiment, the frame 6 serves not only as the mechanical skeleton of the speaker body, but also as the connecting structure in the speaker body that connects to the grille bracket 4.

[0072] Understandably, the speaker frame 6, as the mechanical skeleton of the speaker body, needs to have a certain rigidity in specific implementation. Based on this, in this embodiment, the speaker frame 6 is used as the connection structure between the speaker body and the mask support 4. This can ensure the stability of the speaker body and the mask support 4 after connection. In this way, the application of other auxiliary connection structures can be avoided, which helps to simplify the structure and reduce costs.

[0073] The diaphragm 7 is fixed to the frame 6, and the surface of the diaphragm 7 facing the speaker grille assembly is a reflective surface 701. That is, the speaker assembly in this embodiment is provided with a diaphragm 7 having a reflective surface 701, and the reflective surface 701 of the diaphragm 7 faces the speaker grille assembly.

[0074] In an exemplary embodiment, the diaphragm 7 includes a diaphragm body and a reflective coating disposed on the side of the diaphragm body facing the speaker grille assembly. This reflective coating forms a reflective surface 701. In practical applications, the reflective coating can be a polyester film, an aluminum coating, or a titanium coating, etc.

[0075] In some embodiments, the light-emitting element 8 is a light strip arranged inside the light-shielding groove, surrounding the opening of the light-shielding groove. This arrangement, with light sources on all sides of the speaker mask 5, improves the uniformity of the light display.

[0076] Furthermore, embodiments of this application also disclose a vehicle that includes a controller and a speaker assembly as described in any of the above embodiments.

[0077] A controller is an electronic control unit in a vehicle that manages and controls various non-powered system functions, including but not limited to lighting systems, door locks and anti-theft systems, windshield wipers and washer systems, air conditioning and ventilation systems, power management, and infotainment systems.

[0078] In this embodiment, the speaker assembly is electrically connected to the controller. Thus, the controller can be used to control the light strip in the speaker assembly to be powered on and emit light as needed. The light hits the diaphragm 7 of the speaker body and is emitted through the second part 501 of the speaker cover 5, so that the speaker assembly presents an luminous effect, thereby enhancing the luxurious feel of the vehicle interior.

[0079] Furthermore, it should be noted that since the vehicle includes the speaker assembly mentioned above, the beneficial effects of the speaker assembly on the vehicle are detailed above and will not be repeated here.

[0080] In some embodiments, the vehicle includes a door, which includes a trim panel 1 and a sheet metal part 2.

[0081] Sheet metal part 2 is a metal component that constitutes the main structure of the door, responsible for strength, protection and body rigidity.

[0082] Decorative panel 1 is a non-structural decorative component on the inside of the door. It is fixed to sheet metal part 2 and mainly covers the internal structure of the door, providing aesthetics and functionality.

[0083] In this embodiment, the speaker mask assembly in the speaker assembly is fixedly connected to the decorative panel 1, the speaker body in the speaker assembly is fixedly connected to the sheet metal part 2, and the mask bracket 4 of the speaker mask assembly abuts against the speaker body.

[0084] As described above, the speaker grille assembly is fixed to the decorative panel 1, preventing additional noise from vibration, and the flexible material of the decorative panel 1 can absorb some high-frequency vibrations. The speaker body is fixed to the sheet metal part 2, which ensures the stability of the connection. Furthermore, the vibration generated by the speaker body during operation is directly transmitted to the rigid sheet metal part 2, rather than through the decorative panel 1 to the passenger compartment, thus avoiding any abnormal noise from the decorative panel 1.

[0085] Furthermore, since the speaker grille assembly and the speaker body are fixed to different structural components, both can be disassembled independently, which facilitates later maintenance.

[0086] Regarding the connection method between the speaker grille assembly and the decorative panel 1, as well as between the speaker body and the sheet metal part 2, the specific implementation can be adapted as needed, and this application does not impose specific limitations on this.

[0087] For example, in some embodiments, the speaker grille assembly is connected to the decorative panel 1 by a snap-fit ​​structure, and the speaker body is connected to the sheet metal part 2 by a threaded structure.
