Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail with reference to fig. 1 to 7 in conjunction with examples.

Referring to fig. 1 to 6, a speaker decorating assembly 1000 according to an embodiment of the present invention includes: a speaker cover 100 and a speaker decoration piece 200.

As shown in fig. 1, the speaker trim 200 includes a sound-transmitting region 210 and a mounting portion 220, the mounting portion 220 is disposed in a circumferential direction of the sound-transmitting region 210, that is, the sound-transmitting region 210 is located in a middle region of the speaker trim 200, and the mounting portion 220 is located in an edge region of the speaker trim 200.

Further, as shown in fig. 1 and 5, a plurality of first ribs 231 and second ribs 232 are arranged on the sound-transmitting region 210 in a crossing manner, sound-transmitting holes 233 are enclosed between the first ribs 231 and the second ribs 232, the shape of the sound-transmitting holes 233 can be adjusted according to the arrangement of the first ribs 231 and the second ribs 232, for example, the sound-transmitting holes can be triangular, square, diamond-shaped, or irregular polygon, sound waves generated by sound can be transmitted by air in the sound-transmitting holes 233, and the sound waves can also be transmitted dispersedly by using the first ribs 231 and the second ribs 232 as media.

As shown in fig. 1, the speaker cover 100 is connected to the mounting portion 220, and the speaker cover 100 shields the sound-transmitting region 210, so that sound can be transmitted toward the speaker cover 100 through the sound-transmitting region 210, and the speaker cover 100 can also beautify the speaker decoration member 200.

As can be seen from the above-mentioned structure, in the speaker decoration unit 1000 according to the embodiment of the present invention, the first ribs 231 and the second ribs 232 not only increase the structural strength and rigidity of the sound transmission region 210 and make it difficult to deform, but also the sound transmission holes 233 formed therebetween can ensure a good sound transmission effect, so that the sound generated by the speaker can be transmitted to the speaker cover 100 through the air in the sound transmission holes 233, and can also be transmitted to the speaker cover 100 through the first ribs 231 and the second ribs 232, thereby ensuring that the volume of the sound transmitted from the speaker cover 100 is appropriate, the sound quality of the sound transmitted from the speaker cover 100 is clear, and the noise is small.

In addition, the first ribs 231 and the second ribs 232 can disperse the transmission of the sound waves, so that the frequency of the sound waves transmitted to the speaker cover 100 is changed, the sound waves transmitted to the speaker cover 100 are effectively prevented from being resonant due to the same natural frequency as that of the speaker cover 100, and the probability that the speaker cover 100 vibrates under the excitation of the audio frequency is reduced.

The speaker decoration 200 provides a reliable support for the installation of the speaker cover 100, and also effectively reduces the resonance phenomenon of the speaker cover 100, and the speaker cover 100 beautifies the speaker decoration 200, and the two cooperate with each other and complement each other. The speaker cover 100 is connected to the mounting portion 220 to form a mounting module, which facilitates subsequent mounting on a door trim 2001 (see fig. 7 for the structure of the door trim 2001), and is less prone to rattle after mounting, stable in structure, and capable of reducing abnormal noise caused by vibration.

Compared with the prior art in which the speaker cover is directly connected to the lower trim panel of the vehicle door or the speaker cover is connected to the lower trim panel of the vehicle door through the speaker bracket, the speaker cover 100 of the present invention is connected to the mounting portion 220 to form a mounting module, and then is integrally mounted to the lower trim panel 2001 of the vehicle door, so that the structure is compact, the assembly is convenient, the noise is less, the sound quality is good, and the abnormal sound is not easily generated.

In some embodiments of the present invention, as shown in fig. 1 and 5, the first reinforcing rib 231 has a ring shape, and the plurality of first reinforcing ribs 231 are spaced from the center to the edge of the sound-transmitting region 210, so that two adjacent first reinforcing ribs 231 form a ring-shaped sound-transmitting space between each other. One end of the second reinforcing rib 232 is connected with the assembling portion 220, and the other end of the second reinforcing rib 232 is sequentially provided with a plurality of first reinforcing ribs 231 in a penetrating manner, so that the annular sound transmission space is further divided into more sound transmission holes 233; meanwhile, after the first reinforcing bead 231 and the second reinforcing bead 232 are coupled, the relative positions are fixed, and since the second reinforcing bead 232 is fixed with respect to the position of the fitting part 220, the first reinforcing bead 231 coupled to the second reinforcing bead 232 is also fixed with respect to the position of the fitting part 220. Finally, a plurality of latticed sound-transmitting holes 233 are formed by the first reinforcing ribs 231 and the second reinforcing ribs 232, and the sound-transmitting holes 233 can effectively transmit sound waves with different energy levels. In these examples, it should be noted that the second rib 232 located at the outermost periphery, together with the first rib 231 and the edge of the fitting part 220, surrounds the sound-transmitting hole 233. Then, the sound-transmitting region 210 of the present invention has a stable structure, is not easily deformed, and has a good sound-transmitting performance of the sound-transmitting region 210 under the action of the first ribs 231 and the second ribs 232.

Alternatively, as shown in fig. 1 and 5, the second ribs 232 are radially arranged in the sound-transmitting region 210, the second ribs 232 extend from the first rib 231 at the center to the mounting portion 220, and the radially arranged second ribs 232 can make part of the sound quickly transmit to the mounting portion 220, so that part of the sound can be transmitted to the speaker cover 100 through the solid medium; each second reinforcing rib 232 is connected to the assembling portion 220 after extending from the first reinforcing rib 231 at the middle portion to the first reinforcing ribs 231 at both sides in sequence, so that each second reinforcing rib 232 can stably support and connect each first reinforcing rib 231, and the strength and rigidity of the net structure formed by the first reinforcing ribs 231 and the second reinforcing ribs 232 are further strengthened.

Alternatively, the first reinforcing bead 231 and the second reinforcing bead 232 may be integrally formed to form a stable net-like configuration for convenience of manufacturing.
