[0002] As an essential component of a car's entertainment system, car audio systems are typically mounted directly on the vehicle's interior trim. When the speakers produce sound, they vibrate. However, when the speakers produce certain frequencies, these vibrations can easily resonate with the interior trim, causing unusual noises. Summary of the Invention

Since the mounting ring is fixedly installed on the interior panel of the car, and the cavity is installed on the mounting plate through the first damping rod, shaking is likely to occur between the cavity and the cover plate, so an elastic airbag is provided on the cover body. When the cavity moves, the first damping rod will swing, thereby driving the rotating ball to rotate, and then the elastic airbag is inflated by the connecting component to drive the inflation component. The elastic airbag is further expanded, thereby improving the connection stability between the cover body and the interior panel, and the elastic airbag is an elastic part, which will not cause resonance between the audio system and the car interior panel.

[0008] By adopting the above technical solution, when the cavity shakes, the connecting assembly drives the first connecting rod to swing. At this time, one end of the piston rod abuts against the guide surface. During the swinging of the first connecting rod, the guide surface forces the piston rod to move, thereby pressing the air in the bottle body toward the elastic airbag, causing the elastic airbag to expand.

[0013] Optionally, each guide block is provided with two guide surfaces, and the two guide surfaces are symmetrically arranged so that the two guide surfaces form a V-shaped groove.

[0014] By adopting the above technical solution, since the movement of the cavity in any direction has two positive and negative movement trajectories, the first connecting rod will have two rotations, clockwise and counterclockwise. Therefore, two symmetrical guide surfaces are provided on the guide block, so that the guide surfaces can guide the piston rod when the first connecting rod rotates in any direction.

Therefore, an elastic airbag is provided on the cover body. When the cavity moves, the first damping rod will swing, thereby driving the rotating ball to rotate, and then the inflation component is driven by the connecting component to inflate the elastic airbag. The elastic airbag is further expanded, thereby improving the connection stability between the cover body and the interior panel. The elastic airbag is an elastic part and will not cause resonance between the audio and the car interior panel. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting frame 13 is fixed to the side of the second baffle plate 12 away from the fixed end of the first baffle plate 11. The connecting frame 13 passes through the gap between the second baffle plate 12 and the side wall of the chamber. The end of the connecting frame 13 away from the second baffle plate 12 is fixedly connected to the cover 2, and a gap is formed between the side of the connecting frame 13 and the first baffle plate 11.

[0036] Before installing the loudspeaker 3 , the cavity 1 may be filled with sound-absorbing cotton, polyester cotton and acoustic blanket layer by layer to absorb excess sound waves and ensure the purity of the sound.

[0037] The implementation principle of Example 1 of the present application is as follows: a first baffle plate 11 and a second baffle plate 12 are provided in the chamber. When the audio system is working, sound waves propagate in the cavity 1. The first baffle plate 11 and the second baffle plate 12 can destroy and disperse the standing wave energy, thereby avoiding the reflection and superposition of sound waves of a specific frequency, thereby suppressing the standing waves.

Elastic airbags 21 are fixedly connected to the side of the cover 2 and the side near the cavity 1. The elastic airbag 21 is ring-shaped and coaxial with the cover 2. An inflatable assembly 7 is mounted on the mounting ring 4 and connected to the second connecting rod 63. When the second connecting rod 63 moves, it drives the inflatable assembly 7 to inflate the elastic airbag 21.

[0050] Reference Figure 2 、 Figure 6 and Figure 7The inflatable assembly 7 includes a first connecting rod 71, the middle portion of which is hinged to the surface of the mounting ring 4. A sliding rod 631 is fixedly connected to the surface of the second connecting rod 63 at one end away from the rotating rod 64. The axis of the sliding rod 631 is parallel to the axis of the mounting ring 4. The first connecting rod 71 is located on the side of the second connecting rod 63 away from the mounting ring 4. A waist-shaped groove 711 is formed through the side of the first connecting rod 71 near one end of the second connecting rod 63. The length direction of the waist-shaped groove 711 is parallel to the length direction of the first connecting rod 71. The sliding rod 631 is slidably connected to the waist-shaped groove 711. In order to limit the position of the second connecting rod 63, the end of the sliding rod 631 away from the second connecting rod 63 is coaxially fixedly connected to a limiting ring. Two limiting rings are provided. The first connecting rod 71 is located between the two limiting rings, and the limiting ring abuts against the side of the first connecting rod 71.

[0051] The inflation assembly 7 further includes a bottle body 72, a piston rod 73, and a guide block 74. The bottle body 72 is located at the end of the first connecting rod 71 away from the waist-shaped groove 711 and is fixedly connected to the first connecting rod 71. One end of the piston rod 73 includes a piston 731, which is slidably connected to the cavity 721 of the bottle body 72. The cavity 721 of the bottle body 72, located on the side of the piston 731 away from the first connecting rod 71, is connected to the elastic airbag 21. The connecting pipe between the cavity 721 and the elastic airbag 21 is hidden in the drawings of the specification of this embodiment.

The side of the guide block 74 away from the mounting ring 4 has a guide surface 422, and the abutment ball abuts the guide surface 422.

[0052] When the first connecting rod 71 rotates, the guide surface 422 forces the piston rod 73 to move upward and presses the air inside the bottle body 72 toward the elastic airbag 21, causing the elastic airbag 21 to become larger. The elastic airbag 21 is tightened between the cover body 2 and the interior panel 5 to improve the installation stability of the cover body 2 and the interior panel 5 and reduce the possibility of movement of the cover body 2.

[0053] Reference Figure 7 Each guide block 74 is provided with two guide surfaces 422, which are symmetrically arranged to form a V-shaped groove. Since the movement of the cavity 1 in any direction has two forward and reverse motion trajectories, the first connecting rod 71 can rotate clockwise and counterclockwise. Therefore, two symmetrical guide surfaces 422 are provided on the guide block 74. This allows the guide surfaces 422 to guide the piston rod 73 regardless of the direction of rotation of the first connecting rod 71.

[0054] The implementation principle of this embodiment 2 is as follows: during installation, the cover body 2 and the mounting ring 4 are first fixed in relative position by the positioning rod 22, and then the mounting ring 4 is installed on the mounting frame 52 by the clamping block 42; when the cavity 1 moves, the first damping rod 14 and the second damping rod 61 can buffer the cavity 1, so that the cavity 1 and the interior panel 5 will not resonate, thereby reducing the possibility of abnormal noise, and when the cavity 1 moves, it first drives the rotating ball 441 to rotate, and then drives the second connecting rod 63 to move through the second damping rod 61, thereby driving the first connecting rod 71 to rotate. During the rotation of the first connecting rod 71, the guide surface 422 will force the piston rod 73 to move, and press the air in the bottle body 72 to the elastic airbag 21. The elastic airbag 21 will expand and tighten between the cover body 2 and the interior panel 5, thereby reducing the possibility of movement of the cover body 2 and the cavity 1.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
