[0036] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0037] The following describes the vehicle and its subwoofer system according to the present application with reference to the accompanying drawings.

[0038] like Figures 1 to 5 As shown, a specific embodiment of the present application provides a vehicle subwoofer system 100, including a subwoofer cavity 1 and a subwoofer device 2, wherein the subwoofer cavity 1 is formed inside a vehicle body beam; the subwoofer device 2 is arranged on the vehicle body and connected to the subwoofer cavity 1.

[0039] The vehicle subwoofer system 100 is an important component of the vehicle audio system, which is used to amplify the subwoofer to improve the car sound effect, thereby enhancing the user's listening experience in the vehicle. The vehicle subwoofer system 100 includes a subwoofer cavity 1 for power amplification and a subwoofer device 2 as a sound source. Generally, a larger subwoofer box is selected to form the subwoofer cavity 1, but since the vehicle is provided with a variety of components such as body sheet metal, interior decoration and wiring harness, the arrangement of the subwoofer box is limited. In the present application, the subwoofer cavity 1 is formed by using a body beam, thereby replacing the subwoofer box, thereby facilitating the arrangement of the subwoofer cavity 1.

[0040] Specifically, the vehicle includes a vehicle frame 110 and a plurality of vehicle beams connected to the vehicle frame 110. The interior of the vehicle beams is hollow, and the vehicle beams are generally connected to the vehicle frame 110 by welding. In the actual processing process, it is necessary to select a number of vehicle beams from the plurality of vehicle beams as carriers of the subwoofer cavity 1, and separate the internal cavities of the selected vehicle beams to form the subwoofer cavity 1, thereby achieving coupling between the subwoofer cavity 1 and the vehicle body, thereby increasing the internal usable space of the vehicle.

[0041] Preferably, a plurality of vehicle body beams enclose a mounting area 150, and the subwoofer device 2 is mounted in the mounting area 150, thereby reducing the distance between the subwoofer device 2 and the subwoofer cavity 1, thereby achieving a reasonable arrangement of the subwoofer system.

[0042] Preferably, a mounting opening 3 connected to the subwoofer cavity 1 is provided on the side of the vehicle body beam, and the subwoofer device 2 is connected to the mounting opening 3. Since the vehicle body beam needs to be selectively used as a carrier of the subwoofer cavity 1, the distance between the subwoofer device 2 and the subwoofer cavity 1 is reduced by directly mounting the subwoofer device 2 near the vehicle body beam on which the subwoofer cavity 1 is formed, thereby further improving the rationality of the subwoofer system layout.

[0043] In some embodiments, the vehicle body beam includes a vehicle body longitudinal beam 120, a seat cross beam 130 and a seat longitudinal beam 140, wherein the vehicle body longitudinal beam 120 extends longitudinally and is hollow inside, the seat cross beam 130 extends transversely and is hollow inside, the seat longitudinal beam 140 extends longitudinally and is hollow inside, there are two vehicle body longitudinal beams 120 and they are arranged on both sides of the vehicle body frame 110 in the transverse direction, respectively, and the seat cross beam 130 and the seat longitudinal beam 140 are arranged on the vehicle body frame 110 and are located between the two vehicle body longitudinal beams 120.

[0046] Specifically, the vehicle body longitudinal beam 120 is welded by two U-shaped channel steels. Before welding, a partition piece 4 is arranged in the channel steel and fixed. After welding, the partition piece 4 is tightly connected to the peripheral wall of the vehicle body longitudinal beam 120 to separate the internal cavity of the vehicle body longitudinal beam 120, so that the partition piece 4 and the peripheral wall of the vehicle body longitudinal beam 120 enclose a subwoofer cavity 1. By using the partition piece 4 to freely divide the internal cavity to form the subwoofer cavity 1, the processing technology is simplified, thereby improving production efficiency.

[0047] Preferably, there are two partition members 4 which are arranged at intervals in the longitudinal direction in the vehicle body longitudinal beam 120, a subwoofer cavity 1 is formed between the two partition members 4, and the mounting opening 3 is opened on the side of the vehicle body longitudinal beam 120 between the two partition members 4 and faces inward, and the subwoofer device 2 is arranged on the inner side of the vehicle body longitudinal beam 120, thereby realizing the reasonable arrangement of the vehicle subwoofer system 100.

[0048] Preferably, two partition members 4 are provided in the two vehicle body longitudinal beams 120 located on both sides of the vehicle body frame 110 in the horizontal direction to form two subwoofer cavities 1. The two subwoofer cavities 1 are symmetrically arranged with the central axis extending in the longitudinal direction of the vehicle body frame 110 as the symmetry axis. There are two subwoofer devices 2 and they are connected to the two subwoofer cavities 1 one by one, thereby ensuring the subwoofer performance of the vehicle subwoofer system 100.

The partition 4 is used to separate the internal cavity to form two subwoofer cavities 1 on both sides of the partition 4, thereby simplifying the processing technology and improving production efficiency.

[0053] Specifically, the operator first needs to cut the seat cross beam 130 longitudinally, then put the partition piece 4 into the cut position and make the partition piece 4 tightly connected to the peripheral wall of the seat cross beam 130, and finally weld the seat cross beam 130 to close it.

[0054] Furthermore, the partition member 4 is arranged at the central axis of the seat cross beam 130 extending longitudinally, so as to realize the symmetrical arrangement of the two subwoofer cavities 1, and the installation openings 3 of the two subwoofer cavities 1 are respectively opened on the outward side of the first seat longitudinal beam 141 and the second seat longitudinal beam 142, and the two subwoofer devices 2 are respectively connected to the two subwoofer cavities 1, thereby ensuring the subwoofer performance of the vehicle subwoofer system 100.
