[0002] As users demand a higher level of driving experience, they are also placing greater demands on in-car audio systems. To further enhance the sound quality of in-car audio systems and improve the auditory experience for passengers, some products opt to install subwoofers at the front of the vehicle, specifically in the driver's cabin. However, common in-car subwoofers often suffer from problems such as difficult installation and removal leading to high maintenance complexity, insufficient installation strength, and subpar sound quality. Summary of the Invention

[0003] This utility model provides a car audio system with low maintenance difficulty and good sound effect. It includes an audio body and a sound transmission channel. The audio body is located at the front of the cockpit. The two ends of the sound transmission channel are connected to the audio body and the cockpit respectively. The sound emitted by the audio body can be transmitted to the cockpit along the sound transmission channel.

[0004] Furthermore, the speaker body includes an upper shell and a lower shell, which are connected as one unit by a shell mounting unit located on the periphery of the speaker body. The upper shell and the lower shell form a cavity inside the speaker body, and a vibration sound-generating unit is disposed inside the cavity.

[0005] Furthermore, the speaker body also includes a bass reflex port, which is located in the middle of the upper housing and above the vibrating sound-generating unit. The bass reflex port is used to enhance the low-frequency sound playback effect and make the sound emitted by the speaker body more focused.

[0006] Furthermore, the housing mounting unit includes a nut post that extends upward along the Z-direction of the vehicle body from the upper surface of the upper housing. The nut post is used to form a screw fastening with a bolt extending into the lower housing to relatively fix the upper housing and the lower housing.

[0007] Furthermore, the housing mounting unit also includes a reinforcing rib, which is disposed between the nut post and the upper housing and is connected to the upper surface of the nut post and the upper housing, respectively.

[0008] Furthermore, the sound transmission channel includes a first tube and a second tube, which are connected as one unit. The first tube communicates with the interior of the speaker body, and the second tube communicates with the cockpit.

[0009] Furthermore, the second pipe section includes a connecting part and a fixing part. The connecting part is used to connect with the first pipe section, and the fixing part is used to fix relative to the sheet metal of the water channel. The connecting part and the fixing part are connected as one piece.

[0010] Furthermore, it also includes a waterproof sealing gasket, which is disposed between the sound transmission channel and the sheet metal of the water trough, and the waterproof sealing gasket is used to relatively seal the sound transmission channel and the sheet metal of the water trough.

[0011] Furthermore, this utility model also includes an automotive water-cooled audio system assembly, which includes the aforementioned automotive audio system.

[0012] Furthermore, this utility model also includes a car that includes the aforementioned car audio system.

[0013] The car audio system provided by this invention transmits sound emitted by the speaker body directly to the passenger compartment via a sound transmission channel and sheet metal duct. This simple and intuitive sound transmission path reduces maintenance difficulty and provides excellent sound quality. Furthermore, this invention achieves assembly between the upper and lower housings using a nut post and reinforcing ribs connected to both the upper and lower housings. This results in a simplified structure, lower cost, strong fixation, high installation strength, and reduced maintenance difficulty. Additionally, the bass reflex port located on the top of the upper housing provides powerful bass for the car audio system, enhancing the overall premium feel of the vehicle.

The left and right sides of the top surface in the Y direction of the vehicle body are respectively connected as a whole with the two transition surfaces 223. The lower part of the transition surface 223 in the Z direction of the vehicle body is connected as a whole with the side surface. The lower part of the side surface in the Y direction of the vehicle body is connected as a whole with the audio body 1; the fixing portion 222 is in an "open" - shaped ring structure in the Y - Z cross - section of the vehicle body. The dimension of the fixing portion 222 in the Y - Z cross - section of the vehicle body is larger than that of the connection portion 221. The fixing portion 222 is press - connected as a whole with the sound transmission opening on the water trough sheet metal. Particularly, the automotive audio in the present utility model further includes a waterproof sealing gasket 4. The waterproof sealing gasket 4 is arranged between the sound transmission channel 2 and the water trough sheet metal. The waterproof sealing gasket 4 is used to relatively seal the sound transmission channel 2 and the water trough sheet metal. Specifically, in this embodiment, the side of the waterproof sealing gasket 4 facing the audio body 1 is tightly pressed and sealed with the fixing portion 222 of the second pipe portion 22. The side of the waterproof sealing gasket 4 facing the water trough sheet metal is press - connected as a whole with the water trough sheet metal and relatively sealed. The side of the waterproof sealing gasket 4 facing the audio body 1 is press - connected as a whole with the fixing portion 222 of the second pipe portion 22 and relatively sealed. The waterproof sealing gasket 4 is set to be a ring shape consistent with the fixing portion 222 and the sound transmission opening, that is, the shapes of the three in the Y - Z cross - section of the vehicle body are the same, so that the waterproof sealing gasket 4 is closely attached and sealed with the fixing portion 222 and the sound transmission opening respectively along the X direction of the vehicle body, achieving a good sealing effect.It is easy to understand that the shape of the waterproof sealing gasket 4 can be set according to the shape of the water channel sheet metal and the sound transmission channel 2. In this embodiment, the sound transmission opening is a rounded rectangular opening opened on the side of the water channel sheet metal near the driver's cabin. Therefore, the shape of the fixing part 222 of the second tube 22 on the YZ section of the vehicle body is also a rounded rectangle. The waterproof sealing gasket 4 is made of rubber. The car audio system of this utility model achieves the sealing between the sound transmission channel 2 and the water channel sheet metal through the waterproof sealing gasket 4. Moreover, the waterproof sealing gasket 4 assembled by the pressing method does not require additional snap-fit ​​or adhesive structure, which is economical.
