[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0029] like Figure 1 and Figure 4As shown, the vehicle-mounted speaker sound-transmitting structure of the present invention includes: a speaker fixing seat 100 and a speaker cover 200.

[0030] The speaker mounting base 100 has a sound-transmitting area 110 that passes through the front and back. A plurality of first ribs 120 are provided in the sound-transmitting area 110. Both ends of the first ribs 120 are connected to the edges of the sound-transmitting area 110.

[0031] The speaker cover 200 has a sound-transmitting portion 210 extending from front to back. A plurality of second ribs 220 are disposed within the sound-transmitting portion 210. Both ends of the second ribs 220 are connected to the edges of the sound-transmitting portion 210.

[0032] The speaker cover 200 and the speaker fixing base 100 are arranged in a front-to-back relationship. The speaker cover 200 is connected to the speaker fixing base 100. In the front-to-back projection, each of the first ribs 120 overlaps with one of the second ribs 220.

[0033] In actual use, the speaker mounting base 100 is used to secure the speaker's sound-producing element and the speaker cover 200. In this embodiment, the speaker cover 200 is located on the front side of the speaker mounting base 100, and a speaker mounting slot 130 is provided on the rear side of the speaker mounting base 100. The speaker mounting slot 130 is aligned front-to-back with the sound-transmitting area 110.

[0034] The sound-emitting element is a key component in audio equipment, responsible for converting electrical signals into sound signals. Taking the most common dynamic sound-emitting unit as an example, it includes parts such as a diaphragm, a coil and a permanent magnet. When current passes through the coil, a magnetic field is generated. This magnetic field interacts with the magnetic field of the permanent magnet, causing the coil to move in the magnetic field, thereby driving the diaphragm to vibrate, pushing the surrounding air to generate sound waves. The sound waves of the sound-emitting element are emitted from the rear side of the speaker fixing base 100, pass through the sound-transmitting area 110 and the sound-transmitting part 210 in turn, diffuse into the car, and are finally received by the passengers.

[0035] The diaphragm of the sound-generating element is generally circular in shape. Figure 2 As shown, the sound-transmitting area 110 of this embodiment is circular and is located in the middle of the speaker fixing base 100. Figure 4 As shown, the speaker installation groove 130 of this embodiment is in a semi-spherical shape, and the front end of the speaker installation groove 130 is aligned with the sound-transmitting area 110 .

[0036] The circular sound-transmitting area 110 can correspond to the sound-emitting element. The semi-spherical speaker mounting groove 130 can provide a mounting and fixing base for the sound-emitting element, and can also limit the sound waves to avoid sound leakage.

[0037] In front-to-back projection, the speaker cover 200 of this embodiment has the same shape as the speaker mounting base 100. The edge of the speaker cover 200 wraps around the edge of the speaker mounting base 100. The outer edge of the speaker cover 200 is connected to the outer edge of the speaker mounting base 100 by a snap-fit ​​connection. The snap-fit ​​connection structure between the speaker cover 200 and the speaker mounting base 100 can refer to existing snap-fit ​​structures and will not be described in detail here.

[0038] The shape of the sound-transmitting portion 210 of this embodiment is set according to the shape of the speaker cover 200. The edges of the sound-transmitting portion 210 extend at equal intervals along the edges of the speaker cover 200, so that the sound-transmitting portion 210 can fill most of the area of ​​the speaker cover 200, thereby enhancing the diffusion effect of sound waves.

[0039] The specific shapes of the speaker cover 200 and speaker mounting base 100 need to be determined based on the installation location and the vehicle interior, and will not be described in detail here. It is worth noting that the area of ​​the sound-transmitting portion 210 is larger than the area of ​​the sound-transmitting area 110, and the sound-transmitting portion 210 completely covers the area of ​​the sound-transmitting area 110 to avoid affecting the sound transmission rate.

[0040] The second ribs 220 of this embodiment include second transverse ribs 221 and second longitudinal ribs 222. The second transverse ribs 221 and the second longitudinal ribs 222 are interlaced and connected to each other. Figure 3 The second transverse ribs 221 extend along one side edge of the speaker cover 200. A plurality of the second transverse ribs 221 are arranged at equal intervals, so that the sound-transmitting portion 210 is divided into sound-transmitting grooves between two adjacent second transverse ribs 221.

[0041] The second longitudinal rib 222 is provided on the side of the second transverse rib 221 facing the speaker fixing seat 100 and is fixedly connected to the second transverse rib 221. The speaker cover 200 of this embodiment is an integrally formed part, and the second rib 220 is integrally formed with the speaker cover 200. Figure 3 In this embodiment, the second longitudinal ribs 222 are all in the shape of elongated strips and extend in a straight line. The second longitudinal ribs 222 are evenly distributed along the extending direction of the second transverse ribs 221. In other embodiments, the second longitudinal ribs 222 intersect the second transverse ribs 221 at right angles.

[0042] The first ribs 120 of this embodiment include first transverse ribs 121 and first longitudinal ribs 122, wherein the first transverse ribs 121 and the first longitudinal ribs 122 are interlaced and connected with each other. Figure 1As shown, in the projection in the front-to-back direction, each of the first transverse ribs 121 overlaps with one of the second transverse ribs 221 , and each of the first longitudinal ribs 122 overlaps with one of the second longitudinal ribs 222 .

[0043] The first transverse ribs 121 and the first longitudinal ribs 122 intersect to divide the sound-transmitting area 110 into multiple gridded areas, ensuring the strength of the sound-transmitting area 110 while allowing sound waves to pass through. The first transverse ribs 121 and the first longitudinal ribs 122 overlap with the second transverse ribs 221 and the second longitudinal ribs 222, respectively, reducing multiple obstructions to sound waves and minimizing the impact on sound transmission efficiency.

[0044] like Figures 1 to 3 As shown, in this embodiment, a plurality of second transverse ribs 211 are provided between two adjacent second transverse ribs 211 that overlap with the first transverse ribs 121. The second longitudinal ribs 212 covering the sound-transmitting area 110 are provided in a one-to-one correspondence with the first longitudinal ribs 122.

[0045] Furthermore, the width of some of the second transverse ribs 221 is greater than the width of the remaining second transverse ribs 221. The smaller second transverse ribs 221 can form fine sound channels, providing good protection. The wider second transverse ribs 221 can ensure the strength of the speaker cover 200 and extend its service life.

[0046] This embodiment also provides a vehicle, comprising the vehicle-mounted speaker sound-transmitting structure of the above embodiment.

[0047] The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle must have an electric motor that can output power or store mechanical energy as a generator. If the vehicle is a new energy vehicle, it can be a hybrid or a pure electric vehicle.

[0048] The speaker mount 100 is fixedly connected to a vehicle component, and the speaker cover 200 is positioned on the side of the speaker mount 100 facing the vehicle interior. Installation locations for the speaker mount 100 include, but are not limited to, the front corner of the dash, the underside of the instrument panel, near the A-pillar or triangular window, the inside of a door, or on a seat. The fixing structure of the speaker mount 100 is designed based on the specific vehicle component to be installed. During installation, proper sound insulation and sealing must be ensured.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
