This design makes the speaker heavier, and the sound signal needs to be transmitted to the interior of the vehicle through the sound holes on the mask, which reduces the transmission quality of the sound signal.

[0033] Reference below Figure 1-Figure 4 A speaker assembly 1 for a vehicle according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 4As shown, the speaker assembly 1 for a vehicle according to the present invention comprises: a speaker body 10 and a speaker mask 20, the speaker body 10 is suitable for connecting to a vehicle door, the speaker mask 20 is formed with a sound amplification channel recessed toward the speaker body 10, the speaker body 10 is arranged at the bottom of the sound amplification channel, the speaker mask 20 is formed with a through hole 21 located on the inner wall of the sound amplification channel, and the extension direction of the through hole 21 is orthogonal to the inner wall of the sound amplification channel. In some embodiments, the vehicle door comprises a door inner panel and a door guard plate, an installation space is formed between the door inner panel and the door guard plate, the door guard plate is formed with an installation port communicating with the installation space, the speaker body 10 is accommodated in the installation space and is suitable for connecting to the door inner panel, the speaker mask 20 is accommodated in the installation space through the installation port, one end of the speaker mask 20 is suitable for connecting to the door guard plate, and the other end of the speaker mask 20 is suitable for stopping with the speaker body 10, the speaker mask 20 is formed with a sound amplification channel and the inner wall of the sound amplification channel is formed with a through hole 21, and the extension direction of the through hole 21 is orthogonal to the inner wall of the sound amplification channel.

[0035] It can be understood that the speaker body 10 is suitable for converting electrical signals into sound signals, and the sound signals are transmitted to the interior of the vehicle through the sound amplification channel to provide vocal broadcasting services to the passengers. The sound signal generated by the speaker is divided into two parts. One part of the sound signal facing the sound amplification channel is directly transmitted to the interior of the vehicle through the sound amplification channel, and the other part of the sound signal not facing the sound amplification channel enters the sound amplification channel through the through hole 21 and is transmitted to the interior of the vehicle, thereby improving the quality of the sound signal transmitted by the speaker mask 20, and the end of the sound amplification channel is open, so that the speaker mask 20 has a higher quality of transmitting the sound signal. At the same time, the traditional speaker skeleton is eliminated, the weight of the speaker assembly 1 is reduced, and the interior of the sound amplification channel is visible, so that three-dimensional decorative parts can be set in the sound amplification channel, thereby improving the aesthetics of the speaker assembly 1, and the extension direction of the through hole 21 is orthogonal to the inner wall of the sound amplification channel, so that the axis of the through hole 21 is perpendicular to the inner surface of the speaker mask 20, so that the area of ​​the through hole 21 is maximized, thereby improving the pass rate of the sound signal not facing the sound amplification channel, thereby improving the sound transmittance of the speaker mask 20, and then improving the quality of the sound signal transmitted by the speaker mask 20.

[0036] According to the speaker assembly 1 for a vehicle of the present invention, the speaker body 10 is arranged at the bottom of the sound amplification channel inside the speaker mask 20 and a through hole 21 is arranged on the inner wall of the sound amplification channel, so that the sound signal generated by the speaker can be transmitted to the interior of the vehicle through the sound amplification channel to a greater extent, thereby improving the transmission quality of the sound signal. At the same time, the end of the sound amplification channel is opened to further improve the transmission quality of the sound signal, thereby improving the sound quality of the speaker assembly 1. At the same time, the traditional speaker frame is eliminated to reduce the weight of the speaker, thereby achieving lightweight of the vehicle, and the interior of the sound amplification channel is visible, so that three-dimensional decorative parts can be arranged in the sound amplification channel, thereby improving the aesthetics of the speaker assembly 1.

[0037] In some embodiments, the speaker mask 20 is trumpet-shaped and the sound amplification channel is trumpet-shaped, and the diameter of the sound amplification channel gradually increases in the direction away from the inner panel of the vehicle door, so that the sound signal emitted by the speaker body 10 is gradually amplified through the sound amplification channel and the range gradually becomes wider, thereby enhancing the sound amplification effect of the speaker mask 20, further improving the sound quality of the speaker assembly 1, and at the same time, the speaker mask 20 can present a three-dimensional effect in shape, thereby improving the aesthetics of the speaker assembly 1.

[0038] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the via holes 21 are configured as multiple rows spaced apart along the inner surface of the sound amplification channel, and each row of via holes 21 includes multiple via holes 21 sequentially arranged along the busbar direction of the inner surface. In some embodiments, the inner surface of the speaker cover 20 is spaced apart along the circumferential direction, and each row of via holes 21 includes multiple via holes spaced apart along the busbar direction of the inner surface, thereby improving the sound transmittance of the speaker cover 20 while ensuring the quality of the speaker cover 20, improving the quality of the sound signal transmitted by the speaker cover 20, and thus improving the sound quality of the speaker assembly 1.

[0039] In other embodiments, the via holes 21 are constructed as a plurality of rows spaced circumferentially along the inner surface, and the number of via holes 21 in each row is configured as one. The via holes 21 are suitable for sound signals that are not directed toward the sound amplification channel to pass through and enter the sound amplification channel, thereby improving the quality of the sound signal transmitted by the speaker cover 20. At this time, the cross-sectional area of ​​the via holes 21 is larger to increase the pass rate of the sound signal that is not directed toward the sound amplification channel, thereby improving the sound transmittance of the speaker cover 20, and further improving the quality of the sound signal transmitted by the speaker cover 20.

[0040] According to some embodiments of the present invention, Figure 3 As shown, the speaker mask 20 is suitable for connecting with the door guard plate, and the angle between the inner surface and the extension direction of the door guard plate is α and satisfies: 110°≤α≤140°. In some embodiments, a connecting plate 22 is formed on the periphery of the end of the speaker mask 20 away from the inner door panel, and a snap-in piece 23 is provided on the connecting plate 22. The door guard plate is provided with a snap-in groove corresponding to the snap-in piece 23 at the outer periphery of the mounting opening. The snap-in piece 23 is received in the snap-in groove to fix the speaker mask 20 to the door guard plate, thereby improving the installation efficiency of the speaker mask 20. The angle between the busbar of the inner surface of the speaker mask 20 and any straight line on the plane where the door guard plate is located is α, and 110°≤α≤140°, thereby making the speaker mask 20 have a higher transmission quality for the sound signal and improving the sound quality of the speaker assembly 1. Preferably, α=130°.

[0041] In some embodiments, a storage groove is formed in the door guard plate, and an installation opening is formed at the bottom of the storage groove. After the speaker mask 20 is received in the installation space through the installation opening, the connecting plate 22 can be received in the storage groove and the surface of the connecting plate 22 is located in the same plane as the surface of the door guard plate, thereby improving the aesthetics of the door guard plate.

[0042] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the speaker assembly 1 also includes shock-absorbing cotton, which is arranged between the speaker body 10 and the speaker mask 20. In some embodiments, shock-absorbing cotton 30 is also arranged between the speaker body 10 and the speaker mask 20, and the shock-absorbing cotton 30 is suitable for closing the gap formed between the speaker body 10 and the speaker mask 20 to improve the transmission quality of the speaker assembly 1 to the sound signal. At the same time, when the vehicle is bumpy, the shock-absorbing cotton 30 can avoid collision between the speaker body 10 and the speaker mask 20, thereby extending the service life of the speaker assembly 1.

[0043] According to some embodiments of the present invention, Figure 3-Figure 4 As shown, the angle between the inner surface of the speaker mask 20 and the axis gradually decreases in the direction close to the speaker body 10. It can be understood that the shock-absorbing cotton 30 is arranged around at least part of the periphery of the speaker body 10, and one end of the shock-absorbing cotton 30 is connected to the speaker body 10. Here, one end of the shock-absorbing cotton 30 is preferably bonded to the speaker body 10, and the other end of the shock-absorbing cotton 30 is suitable for abutting against the end of the speaker mask 20 close to the speaker body 10. The angle between the inner surface of the speaker mask 20 and the axis gradually decreases in the direction close to the speaker body 10, so that the inner surface of the speaker mask 20 close to the speaker body 10 is constructed as an arc surface, and the transition between the inner surface of the speaker mask 20 and the inner surface of the shock-absorbing cotton 30 is smoother, thereby improving the transmission quality of the sound signal, thereby improving the sound quality of the speaker assembly 1.

[0044] According to some embodiments of the present invention, Figure 3 As shown, the angle between the edge of the inner surface of the speaker cover 20 facing the speaker body 10 and the axis is β and satisfies: 60°≤β≤70°, so that the transition between the inner surface of the speaker cover 20 and the inner surface of the damping cotton 30 is smoother, improving the transmission quality of the speaker assembly 1 to the sound signal, and at the same time, it can prevent the end of the speaker cover 20 close to the speaker body 10 from continuing to extend until the inner surface of the speaker cover 20 is parallel to the inner surface of the damping cotton 30, reducing the weight of the speaker cover 20. Preferably, β=66°.

[0045] According to some embodiments of the present invention, Figure 4As shown, the distance between the speaker mask 20 and the speaker body 10 is d1, the thickness of the shock-absorbing cotton 30 is d2, and the following conditions are satisfied: d2-d1≥0.4mm. In some embodiments, the speaker mask 20 is formed by processing a plate having a certain thickness, and the angle between the edge of the inner surface of the speaker mask 20 facing the speaker body 10 and the axis is β and the following conditions are satisfied: 60°≤β≤70°. At this time, a part of the end of the speaker mask 20 close to the speaker body 10 will protrude in the direction of the sound amplification channel and the other part will protrude toward the speaker body 10. d2-d1≥0.4mm makes the end of the speaker mask 20 close to the speaker body 10 interfere with the shock-absorbing cotton 30, so that the part of the speaker mask 20 protruding toward the speaker body 10 is covered by the shock-absorbing cotton 30, so that the part of the speaker mask 20 protruding toward the sound amplification channel will not protrude from the surface of the shock-absorbing cotton 30 facing the sound amplification channel, thereby avoiding the protrusion of the end of the speaker toward the sound amplification channel and affecting the transmission quality of the speaker assembly 1 to the sound signal. It can be understood that the value of d2-d1 is determined by the thickness of the speaker cover 20. When the thickness of the speaker cover 20 is 1.2 mm, d2-d1=0.5 mm.

[0046] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the inner surface of the speaker cover 20 defines a sound amplification channel, and the through hole 21 is configured as a circular hole formed on the inner surface. It can be understood that the circular hole is easy to process and can improve the production efficiency of the speaker cover 20.

[0047] According to some embodiments of the present invention, Figure 2 As shown, the speaker cover 20 is constructed as a metal part and has a thickness of m, m satisfies: 1mm≤m≤1.4mm, and the via 21 is formed by laser cutting. It can be understood that the speaker cover 20 is constructed as a metal part to improve the quality of the speaker cover 20, thereby extending the service life of the speaker assembly 1. The thickness m of the speaker cover 20 satisfies: 1mm≤m≤1.4mm, so that the weight of the speaker cover 20 is lighter while ensuring the quality of the speaker cover 20, so as to achieve lightweighting of the vehicle. The via 21 is formed by a laser cutting process, which can ensure the processing quality of the via 21 and improve the production efficiency of the speaker cover 20.

[0048] In some embodiments, a speaker cover 20 constructed of metal parts is formed by a stamping process, and the stamped speaker cover 20 is processed by laser cutting equipment. The robot arm of the laser cutting equipment moves around the periphery of the speaker cover 20 and is suitable for opening a through hole 21 on the speaker cover 20 that is connected to the sound amplification channel, thereby improving the processing accuracy of the through hole 21. At the same time, the processing order of first forming the speaker cover 20 and then opening the hole avoids the deformation of the hole position of the through hole 21 after the speaker cover 20 is processed, thereby avoiding reducing the aesthetics of the speaker cover 20.
