[0034] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings to make the advantages and features of the present disclosure more easily understood by those skilled in the art. It should be noted that the descriptions of these embodiments are intended to facilitate understanding of the present disclosure and do not constitute a limitation of the present disclosure. In addition, the technical features involved in the various embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

[0035] 1 to 3 , this embodiment provides a vehicle-mounted speaker system, including a vehicle-mounted speaker and a vehicle mounting plate 100. The vehicle-mounted speaker includes a cone 12, a positioning support 13, a magnetic circuit system 14, a voice coil 15, a frame 11, and a positioning assembly 2 for pre-fixing the frame 11 to the vehicle mounting plate 100. The frame 11 is provided with a hole 16 communicating with the outside world, with a portion of the cone 12 facing the hole 16. The frame 11 is connected to the cone 12, which is in turn connected to the voice coil 15. One end of the positioning support 13 is fixedly connected to the voice coil 15, and the other end is fixedly connected to the frame 11. The positioning support 13 ensures stable vertical movement of the voice coil 15, preventing it from shaking. The positioning assembly 2 is integrally injection-molded with the frame 11 of the speaker 1, extending upward from the upper surface of the frame 11. During use, positioning assembly 2 is connected to a vehicle mounting plate 100 to mount the speaker in a location such as a vehicle door. Specifically, in this embodiment, positioning assembly 2 is mounted on the door sheet metal or within a trim hole, and the speaker is a dynamic coil speaker. It should be noted that the terms "upper" and "lower" in this embodiment refer to the relative positions shown in FIG2 .

[0036] Furthermore, as shown in Figure 1 , there are multiple positioning assemblies 2, spaced apart along the circumference of the frame 11. Specifically, in this embodiment, there are two positioning assemblies 2. The angle between the two positioning assemblies 2 and the line formed by the speaker's central axis is 100-110°. Specifically, in this embodiment, the angle between the two lines formed by the positioning assemblies 2 and the speaker's central axis is 104°.

[0037] 2 and 3 , the positioning assembly 2 includes at least two positioning members that can be elastically deformed and inserted into the mounting hole 101 on the vehicle mounting plate 100 , with a gap between at least two positioning members, and at least one of the positioning members having an outwardly protruding protrusion 222 , the protrusion 222 having a limiting surface 223 facing the surface of the basin frame 11 to limit the vehicle mounting plate 100 between the upper surface of the basin frame 11 and the protrusion 222 .

[0038] Specifically, the positioning members include a first positioning member 21 and a second positioning member 22 disposed opposite each other. The first positioning member 21 and the second positioning member 22 are made of plastic. Therefore, when squeezed, the first positioning member 21 and the second positioning member 22 will deform. Once the pressure is released, the first positioning member 21 and the second positioning member 22 will return to their original shape. In other words, the first positioning member 21 and the second positioning member 22 can move closer or further apart. When the positioning assembly 2 passes through the mounting hole 101 of the vehicle mounting plate 100, the first positioning member 21 and the second positioning member 22 move closer together. After the positioning assembly 2 has passed through the mounting hole 101 of the vehicle mounting plate 100, the first positioning member 21 and the second positioning member 22 move further apart.

[0039] More specifically, the first positioning member 21 has a first insertion portion 211, the second positioning member 22 has a second insertion portion 221 and a protrusion 222 protruding outward relative to the second insertion portion 221, and the limiting surface 223 of the protrusion 222 abuts against the vehicle mounting plate 100. In other embodiments, a protrusion may also be provided on the first positioning member 21, specifically designed according to the size of the mounting hole on the vehicle mounting plate. The diameter of the mounting hole ranges from 6.5 to 7.0 mm. Specifically in this embodiment, the diameter of the mounting hole is 7.0 mm. Furthermore, both the first positioning member 21 and the second positioning member 22 have a guide bevel 23 to facilitate the insertion of the positioning assembly 2 into the mounting hole 101. The angle between the guide bevel 23 and the horizontal plane is smaller than the angle between the limiting surface 223 and the horizontal plane.

[0040] A reinforcing rib 3 is provided between the first positioning member 21 and the second positioning member 22. The thickness of the reinforcing rib 3 is 1-2 mm. The reinforcing rib 3 and the positioning assembly 2 are fixedly connected or integrally provided. Specifically in this embodiment, the reinforcing rib 3 and the positioning assembly 2 are integrally provided, and the thickness of the reinforcing rib 3 is 1.5 mm. In other embodiments, the reinforcing rib 3 and the positioning assembly 2 can also be connected together by a fixed connection. It should be noted that the role of the reinforcing rib 3 here is to prevent the first positioning member 21 and the second positioning member 22 from being squeezed when passing through the mounting hole 101, and the first positioning member 21 and the second positioning member 22 from breaking due to the force.

[0041] More specifically, the reinforcing rib 3 is positioned between the first insertion portion of the first positioning member 21 and the second insertion portion of the second positioning member 22. The lower surface of the reinforcing rib 3 is connected to the upper surface of the basin frame 11. An opening area 4 is defined between the first and second positioning members 21, 22, and is located above the reinforcing rib 3. The size of this opening area 4 can be adjusted during the installation process. When the first and second positioning members 21, 22 pass through the mounting hole 101, the opening area 4 becomes smaller. After the first and second positioning members 21, 22 pass through the mounting hole 101, the opening area 4 becomes larger, returning to its original state.

[0042] 2 , there is a pad 5 between the speaker frame 11 and the vehicle mounting plate 100. The pad 5 can play a role in shock absorption and buffering.

[0043] The central axis of the speaker is generally perpendicular to the vehicle mounting plate. Since the vehicle mounting plate is vertical, after positioning the speaker using the positioning posts, workers still need to support the speaker while securing it to the vehicle mounting plate using fasteners. These positioning posts only prevent errors and do not provide pre-fixing. This reduces assembly efficiency and flexibility.

[0044] This embodiment provides a vehicle-mounted speaker that not only prevents errors when installed on a vehicle mounting plate, but also provides a pre-fixed assembly, simplifying the installation process and saving time and effort. This embodiment improves upon existing error-proofing techniques, eliminating the need for additional components and costs, while simultaneously achieving both error-proofing and pre-fixed assembly, thereby enhancing the accuracy and robustness of the speaker assembly.

[0045] The working process of the car speaker of this embodiment is as follows:

[0046] Because the first insertion portion 211 of the first positioning member 21 and the raised portion 222 of the second positioning member 22 are similar in shape to a cone, during installation, under the action of the guiding slopes 23 of the first insertion portion 211 and the raised portion 222, the positioning assembly 2 can be smoothly squeezed into the mounting hole 101 of the vehicle mounting plate 100. During the process of the first positioning member 21 and the second positioning member 22 entering the mounting hole 101, the first positioning member 21 and the second positioning member 22 undergo elastic deformation due to being squeezed, and the first positioning member 21 and the second positioning member 22 approach each other or even directly contact each other. After the first positioning member 21 and the second positioning member 22 pass through the mounting hole 101, the first positioning member 21 and the second positioning member 22 recover their deformation and move away from each other. The raised portion 222 of the second positioning member 22 can ensure that the entire connector 2 will not fall off the vehicle mounting plate 100, which not only plays a role in positioning and preventing errors, but also plays a role in pre-installation. The structure is relatively simple, the operation is relatively convenient, and it saves time and effort. Furthermore, because it serves as a pre-installation mechanism, the speaker will not fall even if the operator lets go, facilitating further installation. Specifically, final fixation is achieved using multiple screws. Multiple screws are provided, spaced apart along the circumference of the frame 11. Furthermore, the frame 11 is provided with a first through-hole for receiving the screws, and the vehicle mounting plate is provided with a second through-hole for receiving the screws. After pre-installation, the first and second through-holes are positioned opposite each other, facilitating final fixation.

[0047] The vehicle-mounted speaker of this embodiment has at least the following advantages:

[0048] (1) Solve the problem that the positioning column of existing speakers has only a single function (error prevention function);

[0049] (2) Improve the convenience and flexibility of speaker installation, improve work efficiency, and save time and effort;

[0050] (3) The structure of the connector is simple and reliable and can be used for most speakers.
