DETAILED DESCRIPTION

[0023] observe Figures 1 to 12 The content shown here shows an exemplary operation process for easily removing the panel:

[0024] A car audio system with a conveniently disassembled audio panel comprises a speaker 01, a housing 10, a supporting sheet 11, a panel net 15 and a pressing ring 16. Threads are provided on the inner side of the upper end of the housing 10 and the outer wall of the pressing ring 16. The speaker 01 can be placed in the housing 10 and a plurality of supporting sheets 11 for supporting the lower end surface of the edge of the speaker 01 are formed on the inner wall of the housing 10. The panel net 15 can be inserted between the edge of the speaker 01 and the housing 10. The pressing ring 16 can be tightened on the inner side of the upper end of the housing 10 to press the panel net 15 onto the speaker 01. During use, The user can press the pressure ring 16 with his finger, drive the pressure ring 16 to rotate, and screw the pressure ring 16 out from the inner side of the upper end of the shell 10, so that the panel net 15 on the speaker 01 can be removed, so that the panel net 15 can be cleaned during use or replaced after damage. In addition, after removing the panel net 15, the speaker 01 can be taken out of the shell 10, and the shell 10 can be inspected or replaced. When repairing, there is no need to disassemble other parts in the vehicle, and the corresponding disassembly of the audio can be completed.

[0025] observe Figures 1 to 12 The content shown here shows an exemplary operation process for reducing noise:

[0026] The car audio system further includes a shock-absorbing portion that can be embedded between the lower end of the speaker 01 and the housing 10. The shock-absorbing portion includes an elastic sleeve 02 and a limiting sleeve 03. The elastic sleeve 02 is sleeved on the lower end of the speaker 01 and is fixedly connected to the inner wall of the limiting sleeve 03. Through the constraints of the elastic sleeve 02 and the limiting sleeve 03, the elastic sleeve 02 can buffer the vibration between the lower end of the speaker 01 and the limiting sleeve 03, thereby reducing the vibration generated by the speaker 01 when producing sound and affecting the shock-absorbing portion, thereby reducing the noise generated between some parts of the shock-absorbing portion.

[0027] In addition, the elastic sleeve 02 is made of elastic rubber material and can use its own elastic deformation to stick tightly to the lower end of the speaker 01. At the same time, it uses elastic deformation to reduce the effect of vibration transmission, so that the limiting sleeve 03 is more stable after installation.

[0028] observe Figures 1 to 12 The content presented here shows an exemplary operation process for reducing the impact of vehicle vibration on the speaker 01:

[0029] The shock-absorbing part also includes a positioning sleeve 06 that is sleeved on the limiting sleeve 03. The outer wall of the positioning sleeve 06 is formed with an inner groove 08. An airbag ring 09 that can expand after inflation is fixedly connected to the inner groove 08. A positioning groove 12 corresponding to the inner groove 08 is formed on the inner wall of the lower end of the shell 10. The airbag ring 09 can extend into the positioning groove 12 in the horizontal direction. During the installation process, when the speaker 01 enters the shell 10, the limiting sleeve 03 slides into the positioning sleeve 06, and the positioning sleeve 06 enters the lower end of the shell 10, and then the airbag ring 09 is inflated through the air valve carried by the airbag ring 09, so that the airbag ring 09 expands and enters the positioning groove 12, thereby realizing horizontal shock absorption. The restriction on the positioning sleeve 06 makes the positioning sleeve 06 stably contact the lower end of the shell 10. At the same time, the airbag ring 09 acts as a contact medium between the positioning sleeve 06 and the shell 10. The airbag ring 09 can undergo elastic deformation to avoid collision between the positioning sleeve 06 and the shell 10, so as to avoid the vibration from being transmitted to the positioning sleeve 06 when the vehicle vibration is transmitted to the shell 10 during use, further stably support the positioning sleeve 06 and reduce the impact of vibration on the speaker 01; at the same time, rubber pads are provided at the contact positions between the speaker 01 and the shell 10, which can reduce the impact of vibration transmission between the speaker 01 and the shell 10, making the speaker 01 more stable during use.

[0030] observe Figures 1 to 12 The content shown here shows an exemplary operation process for preventing the speaker 01 from rotating:

[0031] The outer wall of the limiting sleeve 03 is formed with multiple limiting ribs 04, and the inner wall of the positioning sleeve 06 is provided with multiple slots 07, and the multiple limiting ribs 04 can be respectively inserted into the multiple slots 07; when the limiting sleeve 03 slides into the positioning sleeve 06, the multiple limiting ribs 04 can be respectively inserted into the multiple slots 07 to limit the limiting sleeve 03, thereby avoiding rotational contact between the limiting sleeve 03 and the positioning sleeve 06, so that the speaker 01 and the positioning sleeve 06 will not rotate, and the speaker 01 can be kept in a stable state.

[0032] observe Figures 1 to 12 The content shown here shows an exemplary operation process for obtaining hidden connectors:

[0033] The edge of the shell 10 is provided with a plurality of connection holes 13, and a cover sheet 14 is embedded in each connection hole 13; when installing the shell 10, the shell 10 can be installed at a certain position of the vehicle by passing a screw-like connection member through the plurality of connection holes 13. After installation, the cover sheet 14 can be embedded in the connection hole 13 to cover the screw-like connection member, thereby maintaining a beautiful appearance.

[0034] observe Figures 1 to 12 An example operation process that can improve the protection capability of the content shown is:

[0035] The car audio system also includes a mounting shell 18, and a recessed platform 19 is formed on the inner side of the upper end surface of the mounting shell 18. The outer shell 10 can be embedded in the recessed platform 19. The outer shell 10 is connected to the mounting shell 18 by multiple screws passing through multiple connection holes 13; by mounting the outer shell 10 on the mounting shell 18 with screws, the outer shell 18 can be used to provide a layer of shell protection for the speaker 01 on the outside, which can provide protection when an external object hits the audio system in an accident; and the recessed platform 19 can make the surface of the outer shell 10 after installation flush with the mounting shell 18, making it more beautiful and neat.

[0036] observe Figures 1 to 12 The content shown here shows an exemplary operation process that can improve earthquake resistance:

[0037] A sealing ring 20 is fixedly connected to the outer wall surface of the lower end of the mounting shell 18, and the thickness of the sealing ring 20 gradually increases from bottom to top to form an inclined surface; during the installation process, a circular hole is opened at the corresponding position of the vehicle, and then the mounting shell 18 is inserted into the circular hole. At this time, the sealing ring 20 can be squeezed and elastically deformed, which can act as a buffer between the mounting shell 18 and the vehicle. It can not only play a sealing role, but also reduce the vibration transmitted between the mounting shell 18 and the vehicle through the elastic deformation of the sealing ring 20, thereby reducing the impact of the vibration on both, making the audio more stable during use.

[0038] observe Figures 1 to 12 The content shown here can be used to provide an example operation process that is easy to operate:

[0039] The upper surface of the pressing ring 16 is provided with a plurality of grooves 17 distributed axially along the axis of the pressing ring 16; when the user presses the pressing ring 16 with his fingers, the plurality of grooves 17 can increase the friction between the fingers and the surface of the pressing ring 16, making it easier for the fingers to drive the pressing ring 16 to rotate, thereby facilitating the disassembly and installation of the pressing ring 16.

[0040] observe Figures 1 to 12 An example operation process for dust prevention is as follows:

[0041] The inner side of the panel net 15 is affixed with a dustproof net that is easy to disassemble. The dustproof net can prevent outside air from entering the panel net 15 and causing pollution to the speaker 01. The dustproof net can also be removed along with the panel net 15 for replacement or cleaning.
