Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically relating to an installation device and method for a subwoofer speaker, and a vehicle. Background Technology

[0002] As the automotive industry shifts towards high-end and new energy vehicles, in-car audio systems have become a core component for enhancing the overall driving experience. Consumers increasingly demand high-fidelity and immersive sound quality. As a key component determining the low-frequency performance of an audio system, the subwoofer's performance parameters have been continuously upgraded. Rated power has increased from the traditional 50W to 110W, with some models reaching a maximum power of 200W, capable of reproducing frequencies as low as 20Hz. Among these, the DDS subwoofer, with its advantages in frequency stability and signal purity brought by digital frequency synthesis technology, has become the mainstream choice for high-end new energy vehicles.

[0003] To meet the sound quality demands of high-end audio systems, the development of new energy vehicles is constantly increasing the types and number of speakers to pursue comprehensive auditory coverage. However, the limited interior space of the vehicle restricts the installation layout of subwoofers due to constraints imposed by surrounding components, resulting in a continuous reduction in the safe clearance between the subwoofer and these components. Furthermore, the operation of subwoofers generates strong airflow, especially noticeable with high-power DDS subwoofers. This airflow, occurring within a narrow gap, easily drives vibrations in surrounding components, causing severe abnormal noises and significantly degrading the sound quality experience, becoming a core bottleneck in improving the overall audio quality of the vehicle.

[0004] Current technologies for installing in-vehicle subwoofers primarily focus on stability and lack specific anti-noise designs, failing to effectively address noise issues caused by airflow affecting surrounding components. Simply increasing the installation gap conflicts with the compact design requirements of the vehicle and compromises speaker mounting stability. Therefore, there is an urgent need for a subwoofer mounting structure that adapts to tight installation spaces and specifically suppresses noise caused by airflow, ensuring installation stability while avoiding noise problems and meeting the audio quality requirements of high-end new energy vehicles. Summary of the Invention

[0005] To address some or all of the aforementioned technical problems in the prior art, this invention proposes an installation device and method, as well as a vehicle, for a subwoofer.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, the mounting device for the subwoofer 10 includes an anti-noise component 30. This anti-noise component 30 is disposed at the opening 11 of the subwoofer 10. Simultaneously, the anti-noise component 30 is located between a fixing component and a noise-causing component. The fixing component is a part used to fix the subwoofer 10. The noise-causing component is a part facing the opening 11 of the subwoofer 10. Because the noise-causing component is located at the opening 11, the strong airflow generated during the operation of the subwoofer 10 will act on it, causing vibration and noise. The anti-noise component 30 can reduce the noise from the noise-causing component caused by the airflow generated during the operation of the subwoofer.

[0025] This application, by setting an anti-noise component 30 between the fixing component and the noise-generating component at the opening 11 of the subwoofer 10, can effectively block the impact of the strong airflow generated by the subwoofer 10 during operation on surrounding components, thus suppressing vibration and noise. It eliminates the need to increase the installation gap, adapting to the compact design requirements of the vehicle space. While ensuring the installation stability of the subwoofer 10, it avoids compromising the sound quality experience, meeting the core demand of high-end new energy vehicles for high-fidelity audio quality. The structure is simple and highly practical.

[0026] In one embodiment, the anti-noise component 30 is constructed as an acoustic cover. After installation, the acoustic cover is placed over the opening end of the subwoofer 10 and mounted on a fixing member, thereby guiding the airflow generated during the operation of the subwoofer 10 and preventing the airflow from acting on the noise component. In other words, the anti-noise component 30 of this application guides the airflow to change its direction, preventing the airflow from directly acting on the noise component, suppressing vibration noise at the source, without needing to increase the installation gap, taking into account both spatial adaptability and sound quality stability, and has a simple and efficient structure. Figure 1 The arrows indicate the direction of airflow.

[0027] In one application, the fixing component is the rear wheel arch connecting plate 20, and the noise-preventing component is the rear wheel arch guard plate 40. That is, by designing the noise-preventing component 30, the subwoofer 10 can be mounted on the rear wheel arch connecting plate 20, and noise from the rear wheel arch guard plate 40 can also be effectively prevented. Specifically, the mounting device for the subwoofer includes a first mounting part 21 and a connecting hole 22. The first mounting part 21 is located on the outer side of the rear wheel arch connecting plate 20 of the vehicle (the side opposite to the geometric center of the rear wheel arch connecting plate 20). The first mounting part 21 is used to position and fix the open end of the subwoofer 10. The connecting hole 22 is also provided on the rear wheel arch connecting plate. The connecting hole 22 communicates with the opening 11 of the subwoofer 10 and matches it in shape and size.

[0028] Therefore, the subwoofer 10 can be positioned and fixed to the rear wheel arch connecting plate 20 using this mounting device, instead of... Figure 7 The subwoofer 10' is thus positioned in the trunk floor connection area. Furthermore, the shape and size of the connecting hole 22 on the rear wheel arch connecting plate 20 match the opening 11 of the subwoofer 10, ensuring smooth sound wave transmission. Therefore, the mounting device for the subwoofer 10 in this application not only solves the problem of vehicle body noise but also makes full use of unused vehicle body space. Figure 6 The installation method can eliminate the need for, for example Figure 7 That traditional installation method frees up a lot of luggage space, balancing sound quality and practicality.

[0029] In one example, a bent plate 23 is provided on the first mounting portion 21. One side of the bent plate 23 is connected to the first mounting portion 21, for example, by welding. The other side of the bent plate 23 is connected to the open end of the subwoofer 10, for example, by fastener connection. This arrangement can stably position the subwoofer 10 at the first mounting portion 21, improving fixation stability, adapting to the operating conditions of the DDS subwoofer, and not occupying luggage space.

[0030] In actual use, the DDS subwoofer 10 has a relatively large power configuration to meet the subwoofer output requirements. While this design feature brings excellent sound effects, it also causes abnormal noise problems. When the DDS subwoofer 10 is working (especially during the air exchange between the vehicle's interior and exterior), its opening 11 is directly facing the rear wheel arch protector 40. The rear wheel arch protector 40 is made of materials with low rigidity, such as hard felt, and is a soft protective component. As the number of components in the vehicle increases, after meeting the installation requirements of all components, the safety gap between the rear wheel arch protector 40 and the rear wheel arch connecting plate 20 becomes extremely limited. This causes the high-speed pulsating airflow at the opening 11 of the subwoofer 10 to be unable to diffuse effectively, directly acting on the surface of the insufficiently rigid rear wheel arch protector 40, forcing the rear wheel arch protector 40 to vibrate under pressure. This forced vibration intensifies with the increasing frequency of airflow pulsation, eventually producing a noticeable slapping sound. This noise is particularly pronounced when playing music with heavy bass (such as "Bad Guy" and "Anhe Bridge"), disrupting the overall audio experience and driving comfort, and creating a user experience that requires improvement. In this application, the noise-blocking component 30 effectively prevents this problem, allowing the subwoofer 10 to be safely installed in the rear wheel arch area, saving trunk space and enhancing the user experience.

[0031] In one specific embodiment, the acoustic cover includes a housing 31, an opening 32, and an abutment edge 33. The housing 31 is a groove-shaped structure, for example, matching the shape of the opening 11 of the subwoofer 10, and is generally square-grooved. The opening 32 is located at one end of the housing 31 and communicates with the inner cavity of the housing 31 to allow airflow. The abutment edge 33 is located on the wall of the opening end of the housing 31, and is an outwardly flared plate, mainly used for connection. After the acoustic cover is installed, the abutment edge 33 abuts against the inner side of the rear wheel arch connecting plate 20, and the housing 31 and the opening 11 of the subwoofer 10 form a receiving cavity, with the opening 32 located at the lower end of the receiving cavity facing the ground. After the airflow generated by the operation of the subwoofer 10 enters the receiving cavity, it is guided along the housing 31 and discharged to the ground from the opening 32, preventing the airflow from impacting the rear wheel arch guard plate 40 and other noise-causing components. As can be seen, the acoustic cover structure of this application has strong adaptability, eliminates abnormal noise from the source through directional exhaust flow, ensures installation firmness along the contact line, and the compact structure does not require additional reserved gaps, thus balancing space utilization and sound quality stability.

[0032] A second connecting portion 24 is provided on the inner side of the rear wheel housing connecting plate 20 (the side close to the geometric center of the rear wheel housing connecting plate 20). At the same time, a connecting member 34 is provided on the housing 31. There are at least two connecting members 34, which are distributed at intervals. According to actual needs, structurally, the connecting member 34 can be a part of the housing 31 (such as Figure 3 the connecting member 34 at the lower end in Figure 3 ), or it can be a plate-like member extending outward from the housing 31 (such as Figure 4 the connecting member 34 at the upper end in Figure 4 ). The positions and quantities of the second connecting portion 24 and the connecting member 34 correspond to each other. Structurally, the structure of the second connecting portion 24 can be in the shape of a bracket. For example, according to different installation positions, it can be constructed as a convex sheet (such as Figure 4 the second connecting portion 24 at the upper end in Figure 4 ), or it can be constructed as a "U" shape (such as the second connecting portion 24 at the lower end in Figure 4 ). Connecting bolt holes are provided on each of the second connecting portion 24 and the connecting member 34. During the installation process, the second connecting portion 24 and the connecting member 34 are firmly connected by using connecting bolts, and then the anti-abnormal noise member 30 is arranged on the rear wheel housing connecting plate 20. In this application, by performing fixed connections at at least two locations, the connection stability can be effectively guaranteed, the local mode of the acoustic cover can be ensured, so that even if the high-speed pulsating air flow generated when the DDS subwoofer 10 works directly beats on the surface of the acoustic cover, the stable connection makes the acoustic cover not vibrate, thereby eliminating the occurrence of audio excitation abnormal noise. In addition, the bolt connection method in this setting is convenient for disassembly and assembly, facilitating later maintenance, and at the same time, the connection stability is strong. It can be seen that the above setting eliminates abnormal noise from the source by directional exhaust, the compact structure adapts to the limited space of the whole vehicle, and both the installation practicability and the sound quality stability are considered.

[0033] The acoustic cover conforms to the gap between the rear wheel housing connecting plate 20 and the rear wheel housing guard plate 40. That is to say, the main body of the acoustic cover generally extends in a curved manner along the arc of the rear wheel housing connecting plate 20. The acoustic cover is an injection molded part. For example, the acoustic cover can be made of one of PP (polypropylene), ABS, and PP+GF (glass fiber reinforced polypropylene) materials. The acoustic cover being an injection molded part has convenient shaping and easy process implementation, can conform to the arc-shaped gap between the rear wheel housing connecting plate 20 and the rear wheel housing guard plate, accurately fill the space, and improve the adaptability of the compact layout and the structural fit.

[0034] The structural design of the acoustic cover has excellent space adaptability. For the narrow gap of only 15 - 20 mm between the DDS subwoofer opening 11 and the rear wheel housing guard plate 40, it can adapt to the compact space to solve the installation problem, and there are no special requirements for the inherent structure of the rear wheel housing connecting plate, and it can be conveniently added as a retrofit part to the existing structure.

[0035] A first foam element 36 is provided on the abutment edge 33. After installation, the first foam element is positioned between the abutment edge 33 and the rear wheel arch connecting plate 20. By providing the first foam element, the fitting gap is filled, vibration is buffered, and airflow leakage is prevented, further enhancing the anti-noise effect and connection sealing performance. The first foam element 36 can be attached to the abutment edge 33 by adhesive bonding.

[0036] A second foam element 35 is provided on the outer wall of the housing 31, for example, by adhesive bonding. Multiple second foam elements 35 can be provided, spaced apart on the wall of the housing 31. Considering that the rear wheel arch protector 40 may collide with the acoustic cover due to vibration when the vehicle is driving on bumpy roads, thus generating new abnormal noises, this solution involves attaching multiple second foam elements 35 to the side of the acoustic cover facing the rear wheel arch protector 40. This arrangement utilizes the good elasticity and cushioning properties of foam, effectively absorbing collision energy and preventing direct contact between the two, thus avoiding impact noise and further ensuring the integrity and reliability of the noise reduction solution.

[0037] This application also relates to a vehicle. The vehicle includes a rear wheel arch connecting plate 20, a rear wheel arch guard 40 disposed inside the rear wheel arch connecting plate 20, a subwoofer 10, and the aforementioned mounting device for the subwoofer. The mounting device for the subwoofer features a fixing component on the rear wheel arch connecting plate 20 and a noise-preventing component on the rear wheel arch guard 40. The subwoofer 10 is mounted on the rear wheel arch connecting plate 20. A noise-preventing component 30 is fixed to the rear wheel arch connecting plate 20 and located between the rear wheel arch connecting plate 20 and the rear wheel arch guard 40. Therefore, mounting the subwoofer 10 on the rear wheel arch connecting plate 20 optimizes its installation position and frees up trunk space. Simultaneously, the noise-preventing component 30 isolates the rear wheel arch guard 40 from airflow, preventing noise and improving the customer experience.

[0038] This application also relates to a method for installing a subwoofer. In this method, the subwoofer 10 is fixed to the rear wheel arch connecting plate 20 of the vehicle by means of a bending plate 23 in the subwoofer mounting device. Additionally, an anti-noise component 30 in the subwoofer mounting device is applied between the rear wheel arch connecting plate 20 and the rear wheel arch guard 40 to guide airflow and prevent the airflow generated by the subwoofer 10 during operation from directly acting on the rear wheel arch guard 40. In the above installation method, on the one hand, the bending plate 23 securely fixes the subwoofer 10 to the rear wheel arch connecting plate 20, ensuring reliable connection and convenient assembly, thus completing the installation of the subwoofer 10; on the other hand, the anti-noise component 30 guides airflow, effectively eliminating audio excitation noise that may be caused by the airflow during the operation of the subwoofer 10.
