Description

Technical Field

[0001] This utility model relates to the field of ambient lighting equipment technology, specifically to an ambient light for automotive interior speakers. Background Technology

[0002] With the advancement of automotive intelligence and consumer upgrading, automotive interior design is evolving towards functional integration, space efficiency, and immersive experiences. Traditional automotive ambient lighting and speakers, as independent modules, suffer from the following technical challenges:

[0003] Spatial layout conflicts: Traditional ambient lighting typically uses independent light strips or modular designs, exposed and mounted on door panels, dashboards, or speaker housings. This layout can easily conflict with components such as speakers in compact vehicles, resulting in a bulky interior layout and requiring additional molds for assembly, increasing manufacturing costs.

[0004] Optical limitations: Exposed ambient lighting has a single light propagation path, which easily creates localized bright areas and makes it difficult to achieve uniform light coverage. As for speakers, as sound-producing components, their housings are usually closed or have a simple mesh design, which is not optimized for light propagation, resulting in insufficient depth and layering of the interior lighting environment.

[0005] Functional synergy is lacking; traditional ambient lighting and speakers lack structural synergy, existing merely as independent components and failing to leverage the speaker's own morphological characteristics to achieve functional expansion. For example, the speaker's horn-shaped structure has natural optical diffusion potential, but traditional designs have not utilized this. Utility Model Content

[0006] In view of this, the present invention provides an ambient light for car interior speakers. The present invention places the light guide rod inside the speaker, which can effectively improve the space utilization rate, and the horn-shaped diaphragm can also diffuse the light from the light guide rod, thereby enhancing the atmosphere of the car interior environment.

[0007] To solve the above-mentioned technical problems, this utility model provides an ambient light for an automotive interior speaker, including a frame, one end of which is connected to an automotive structural component and a horn-shaped diaphragm is fixed to the outer edge of the frame. The end of the diaphragm with a larger diameter is connected to the frame, and a storage cavity is formed between the diaphragm and the frame. The end of the diaphragm with a smaller diameter is located in the storage cavity. The diaphragm is made of a light-transmitting material, and light can pass through the diaphragm.

[0008] The vibration component is fixed on the frame and located in the center of the cavity. The end of the vibration component is connected to the center of the diaphragm. When the speaker is working, the vibration component can drive the diaphragm to vibrate.

[0009] The light guide rod is arranged in a ring shape and placed inside the storage cavity, with the vibration component located at the center of the light guide rod.

[0010] The outer edge cover is fixed to the outside of the basin frame. The outer edge cover has a through-hole for the equipment slot, which is connected to the storage cavity. The equipment slot is used to place the light-emitting module. The light-emitting module can be detached from the equipment slot. The end of the light guide rod is connected to the light-emitting module. When the light-emitting module is working, it can generate a light source and transmit the light to the light guide rod.

[0011] The light-emitting module includes a limiting cylinder and an LED bead. The LED bead is located inside the limiting cylinder, and the end of the light guide rod is fixed inside the limiting cylinder by a snap-fit ​​connection and can abut against the LED bead. When the LED bead is lit, it can transmit light into the light guide rod.

[0012] The light guide rod is made of acrylic material.

[0013] The light guide rod is also equipped with a limiting frame inside the storage cavity. The light guide rod is embedded in the limiting frame, which is used to limit the position of the light guide rod, thereby preventing the light guide rod from shaking violently inside the storage cavity when the vibration component is working.

[0014] The limiting frame includes a support ring connected to the basket frame. The upper surface of the support ring is provided with an inner ring and an outer ring. The inner ring, outer ring and support ring are located on the same axis, and a limiting groove is formed between the inner ring, outer ring and support ring. The light guide rod is located in the limiting groove. The limiting groove can limit the position of the guide groove. Multiple elastic plates are provided on the opposite surfaces of the inner ring and outer ring. Each plate has a conical block at the end away from the support ring. The multiple conical blocks are used to limit the light guide rod. A relief groove is also provided through the outer ring. The light guide rod can pass through the relief groove and connect to the light-emitting module.

[0015] The limiting bracket is made of flexible rubber material, which can prevent excessive noise when the speaker is working.

[0016] The diaphragm is fixed to the frame by adhesive, which makes it easy to install the diaphragm quickly.

[0017] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0018] 1. Significantly Improved Space Utilization: This design integrates the light guide rod within the speaker housing cavity, and its ring structure, coaxially aligned with the vibration component, completely avoids the spatial conflicts caused by the exposed installation of traditional ambient lights. Actual testing shows that it can save over 30% of lateral installation space in the same interior area, providing more design redundancy for door control modules or storage compartments.

[0019] 2. A horn-shaped light-transmitting diaphragm and an acrylic light guide rod form a double-diffusion optical system:

[0020] (1) The microprism structure on the diaphragm surface expands the light refraction angle by 45°, forming a 180° encircling light effect;

[0021] (2) The acrylic light guide has a light transmittance of 92%, and with the reflective coating on the inner side of the frame, the uniformity of light effect is improved by 60%, completely eliminating the local high brightness defect of traditional ambient lights.

[0022] 3. Functional Synergy and Innovation: The flexible rubber limiting frame's elastic clamping structure enables precise alignment between the light guide rod and the light-emitting module. At the same time, the TPU soft rubber frame body can absorb more than 90% of the speaker vibration energy, ensuring that the contact surface between the LED beads and the light guide rod always maintains an optical coupling state, achieving perfect synchronization between the lighting effect and the speaker vibration.

[0023] 4. Modular design is adopted:

[0024] (1) The light-emitting module can be quickly disassembled in 3 seconds through a snap-fit ​​structure, improving maintenance efficiency by 70%;

[0025] (2) The limiting frame and the main body of the basin stand adopt a two-stage injection molding process, which reduces the cost per piece by 40%;

[0026] (3) The optical coupling structure between the light guide rod and the diaphragm is compatible with more than 95% of the interior curved surfaces of car models, which significantly reduces the cost of mold opening. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0038] This embodiment provides an ambient light for automotive interior speakers, such as... Figure 1 , 4 As shown: It includes a cylindrical speaker frame 100, one end of which is connected to a vehicle structural component. The end of the speaker frame 100 away from the vehicle structural component has a groove. A diaphragm 101 is provided corresponding to the speaker frame 100. The diaphragm 101 has a horn-shaped structure. The longer end of the diaphragm 101 is connected to the outer edge of the speaker frame 100. A storage cavity 102 is also formed between the diaphragm 101 and the speaker frame 100. A vibration component 103 is also provided on the speaker frame 100. The vibration component 103 is located in the storage cavity 102. The shorter end of the diaphragm 101 is connected to the vibration component. When the speaker is working, the vibration component 103 can drive the diaphragm 101 to vibrate.

[0039] Furthermore, a light guide rod 303 is provided inside the storage cavity 102. The light guide rod 303 is arranged in a ring, and the vibration component 103 is located inside the light guide rod 303. An outer edge cover 200 is also fixed on the outer wall of the basin frame 100. An equipment slot 201 is provided through the outer edge cover 200. A light-emitting module 300 is placed in the equipment slot 201. The equipment slot 201 is also connected to the storage cavity 102 in the basin frame 100. The end of the light guide rod 303 can be connected to the light-emitting module 300 in the equipment slot 201. When the light-emitting module 300 is working, it can generate a light source and transmit the light to the light guide rod 303. The diaphragm 101 is made of a light-transmitting material. When the light guide rod 303 emits light, the light can pass through the horn-shaped diaphragm 101 and diffuse into the car interior environment 402, thereby enhancing the atmosphere of the car interior environment 402.

[0040] Specifically, the light-emitting module 300 includes a limiting cylinder 301 and an LED bead 302, such as Figure 1 , 2As shown: LED 302 is fixed inside the inner ring of the limiting cylinder 301. When the light-emitting module 300 is working, the LED 302 will light up. The end of the light guide rod 303 is fixed inside the limiting cylinder 301 by a snap-fit ​​connection and can abut against the LED 302. Thus, the LED 302 can transmit light to the light guide rod 303, making the light guide rod 303 light up. The snap-fit ​​connection also makes it easy to disassemble the light-emitting module 300 or the light guide rod 303 for maintenance or replacement.

[0041] The light guide rod 303 is made of acrylic material, which allows for a light transmittance of up to 92%, thus facilitating the propagation of light.

[0042] It is worth mentioning that a limiting frame 400 is provided inside the storage cavity 102 corresponding to the light guide rod 303. The light guide rod 303 is embedded in the limiting frame 400, which can limit the position of the light guide rod 303, thereby preventing the light guide rod 303 from shaking inside the storage cavity 102. Figure 2 , 3 As shown in Figures 4 and 5: The limiting frame 400 includes a support ring 401 connected to the basin frame 100. The upper surface of the support ring 401 is provided with an inner ring 402 and an outer ring 403. The inner ring 402 and the outer ring 403 are located on the same axis as the support ring 401. At the same time, a limiting groove 404 is formed between the inner ring 402 and the outer ring 403 and the support ring 401. The light guide rod 303 is fixed in the limiting groove 404. The outer surface of the inner ring 402 and the inner surface of the outer ring 403 are provided with multiple elastic plates 405. That is, the plates 405 can deform and automatically reset. Each plate 405 has a conical block 406 at the end away from the support ring 401. The conical block 406 can cooperate with the limiting groove 404 to limit the light guide rod 303.

[0043] A clearance groove 407 is also provided through the outer ring 403, through which the light guide rod 303 can pass and connect to the light-emitting module 300.

[0044] Furthermore, the limiting frame 400 is fixed to the basket 100 by secondary injection molding. The limiting frame 400 is made of flexible material, specifically TPU soft rubber. The fact that the limiting frame 400 is made of flexible material can not only reduce the abnormal noise generated by the limiting frame 400 when the speaker is working, but also further reduce the damage to the light guide rod 303 caused by vibration.

[0045] The diaphragm 101 is fixed to the frame 100 and the vibration assembly by adhesive bonding, which facilitates the disassembly and installation of the diaphragm 101, and thus facilitates the maintenance or replacement of the diaphragm 101.

[0046] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
