Description

Technical Field

[0001] This application relates to the field of loudspeaker technology, specifically to a loudspeaker mask, a loudspeaker, and a vehicle. Background Technology

[0002] As people's living standards improve, cars have gradually become an essential means of transportation for most families. Cars are generally equipped with audio systems, and speakers are an important component of these systems.

[0003] Generally, a loudspeaker includes a speaker grille. The speaker grille has openings that allow sound to be transmitted. However, existing loudspeakers lack structural strength and are easily damaged or deformed under external pressure. Utility Model Content

[0004] The purpose of this application is to provide a speaker grille, a speaker, and a vehicle to solve the problem of insufficient structural strength in existing speakers.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, embodiments of this application provide a speaker grille, including a grille body and a support structure. The grille body has a sound passage hole that extends through the grille body. The support structure is located on one side of the grille body and connected to it. The support structure includes multiple support units. Each support unit includes a first support portion and a second support portion. One end of the first support portion is connected to the grille body, and the other end is connected to one end of the second support portion. The second support portion is inclined relative to the first support portion, and the other end of the second support portion is located away from the grille body relative to one end of the second support portion.

[0007] According to the above-described technical means, the speaker grille provided in this application embodiment allows multiple support units to jointly support the grille body. Each support unit can be connected to the grille body via a first support portion. Because the second support units are inclined relative to the first support unit, the support strength of the multiple second support units is higher. Thus, through multiple support units, the grille body can be effectively supported, thereby improving the structural strength of the speaker.

[0008] In one possible implementation, the number of second support portions in the support unit is multiple. These multiple second support portions are spaced apart circumferentially along the first support portion.

[0009] Based on the above-mentioned technical means, the support performance of the support structure can be further improved by using multiple second support parts, thereby further enhancing the support strength.

[0010] In one possible implementation, the number of second support portions in the support unit is three. The other end of each second support portion in the support unit is connected to the other end of the second support portion of an adjacent support unit.

[0011] Using the aforementioned technical methods, multiple support units can be interconnected to form a three-dimensional mesh structure. In this configuration, the support structure can provide high support strength, ensuring effective support.

[0012] In one possible implementation, the diameter of the sound hole is less than or equal to 0.3 mm.

[0013] According to the above-described technical means, the speaker grille provided in this application embodiment has a sound hole on its main body, allowing audio to be transmitted through the sound hole and ensuring that audio can be transmitted normally from the inside of the speaker. Since the diameter of the sound hole is less than or equal to 0.3mm, the small diameter makes it difficult for external foreign objects to enter the speaker's interior, thus ensuring the cleanliness of the speaker's interior. Furthermore, the small diameter of the sound hole also prevents the internal structure of the speaker from being exposed, thereby improving the overall appearance of the speaker.

[0014] In one possible implementation, the porosity of the mask body is less than or equal to 35%.

[0015] According to the above technical means, when the porosity of the mask body is small, the audio can be better transmitted from the sound holes on the mask body, ensuring the audio transmission effect.

[0016] In one possible implementation, the mask body includes a substrate. Sound transmission holes are formed on the substrate. The substrate is made of aluminum.

[0017] According to the above-mentioned technical means, since the substrate is made of aluminum, it has high strength.

[0018] In one possible implementation, the mask body further includes a protective layer. The protective layer covers the surface of the substrate and serves to protect the substrate.

[0019] Based on the above technical means, the protective layer can protect the substrate and extend its service life.

[0020] In one possible implementation, the protective layer is an aluminum oxide layer.

[0021] Using the aforementioned techniques, aluminum oxide can form a dense protective film, providing better protection.

[0022] In one possible implementation, the support structure is fabricated using 3D printing.

[0023] Based on the aforementioned technical means, the support structure can be manufactured using 3D printing, making the manufacturing process simpler and more convenient.

[0024] Secondly, embodiments of this application provide a loudspeaker, including any of the loudspeaker covers described in the first aspect.

[0025] The loudspeaker provided in this application embodiment includes any of the loudspeaker covers in the first aspect, which can solve the same technical problems as loudspeaker covers and achieve the same technical effects, and will not be described in detail here.

[0026] Thirdly, embodiments of this application provide a vehicle including the speaker of the second aspect.

[0027] The vehicle provided in this application embodiment, since it includes a speaker of the second aspect, can solve the same technical problem as the speaker and achieve the same technical effect, which will not be repeated here. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] This application provides a vehicle. The specific type of vehicle is not specifically limited in this application; for example, the vehicle provided in this application can be an electric vehicle, a hybrid electric vehicle, or a solar-powered vehicle. Furthermore, the vehicle provided in this application can also be of different forms. For example, the vehicle provided in this application can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV).

[0035] The vehicle may include a frame. The frame may form the overall shape of the vehicle's exterior and create a passenger seating space. The frame may include door structures through which users can enter and exit.

[0036] Furthermore, to enable vehicle propulsion, the vehicle may also include an electric drive system assembly. The electric drive system assembly may include an electric drive system. This electric drive system may include a drive motor and a reducer. The drive motor provides power, and the reducer can be connected to the drive motor. The reducer can regulate the speed, allowing the vehicle to operate at different speeds. Depending on the driving method, the electric drive system can be categorized into front-wheel drive, rear-wheel drive, and four-wheel drive configurations.

[0037] In addition, the vehicle may include a transmission system that can be connected to an electric drive system to transmit power generated by the engine to the wheels.

[0038] To supply power to electrical components such as the drive motor, the vehicle provided in this application embodiment also includes a battery system. The battery system may include a battery pack, which can be used to provide electrical energy. The battery pack can be connected to the vehicle's electric drive system and other electrical components. In this way, the electrical energy from the battery pack can be transferred to various components of the vehicle for power supply.

[0039] The vehicle provided in this application embodiment may further include an audio system for playing audio. The audio system may include a speaker. The speaker can output audio. The speaker may include a speaker grille. The speaker grille serves a protective function.

[0040] like Figure 1 As shown, the speaker grille 100 provided in this embodiment may include a grille body 10. For example... Figure 2 As shown, the mask body 10 may have a sound passage hole. The sound passage hole extends through the mask body 10. In this way, audio can be transmitted through the sound passage hole on the mask body 10, ensuring that the audio can be transmitted normally from the inside of the speaker.

[0041] The diameter of the sound hole can be less than or equal to 0.3 mm. Because the sound hole is small, it prevents foreign objects from easily entering the speaker's interior, thus ensuring internal cleanliness. Furthermore, the small diameter also minimizes the exposure of the speaker's internal structure, improving its overall appearance.

[0042] Understandably, the diameter of the sound hole can be designed according to the actual situation. For example, the diameter of the sound hole can be 0.1mm-0.3mm. For instance, the diameter of the sound hole can be 0.3mm, 0.2mm, or 0.1mm. Furthermore, the manufacturing method of the sound hole can be selected according to the actual situation. For example, the sound hole can be formed using laser drilling technology.

[0043] It is understandable that multiple sound holes can be evenly distributed on the mask body 10. Of course, multiple sound holes can also be non-uniformly distributed on the mask body 10. Furthermore, the spacing between two adjacent sound holes can be designed according to actual conditions. For example, the spacing between two adjacent sound holes can be 0.1mm, 0.2mm, or 0.3mm.

[0044] In some embodiments, the porosity of the mask body 10 is less than or equal to 35%. When the porosity of the mask body 10 is small, audio can be transmitted better from the sound holes on the mask body 10, ensuring audio transmission quality. It is understood that the specific selection of the porosity of the mask body 10 can be designed according to actual conditions. For example, the porosity of the mask body 10 can be 35%, 30%, or 25%.

[0045] In some embodiments, the speaker grille 100 further includes a support structure 20. The support structure 20 is located on one side of the grille body 10 and connected to the grille body 10. Thus, by providing the support structure 20, the structural strength of the speaker grille 100 can be improved, thereby extending the service life of the speaker grille 100 and ensuring its performance.

[0046] Understandably, when the porosity of the mask body 10 is small, the strength of the mask body 10 itself will decrease. At this time, the supporting structure 20 can improve the overall strength of the speaker mask 100, ensuring the performance.

[0047] Of course, in some other embodiments, the speaker grille 100 may also consist only of the grille body 10. In this case, a high-strength material can be selected to make the grille body 10.

[0048] In some embodiments, such as Figure 1As shown, the support structure 20 may include multiple support units 21. Each support unit 21 includes a first support portion 211 and a second support portion 212. One end of the first support portion 211 is connected to the mask body 10, and the other end is connected to one end of the second support portion 212. The second support portion 212 is inclined relative to the first support portion 211, and the other end of the second support portion 212 is located away from the mask body 10.

[0049] Therefore, in the speaker grille 100 provided in this embodiment, multiple support units 21 can collectively support the grille body 10. The support units 21 can be connected to the grille body 10 via a first support portion 211. Since the second support units 212 are inclined relative to the first support unit 211, the support strength of the multiple second support units 21 is higher. Thus, the multiple support units 21 provide good support for the grille body 10, thereby improving the structural strength of the speaker.

[0050] In some embodiments, the number of second support portions 212 in the support unit 21 is multiple. The multiple second support portions 212 are arranged at circumferential intervals along the first support portion 211. Thus, the support performance of the support structure 20 can be further improved by using multiple second support portions 212, thereby further enhancing the support strength. Of course, in other embodiments, the number of second support portions 212 in the support unit 221 may also be one.

[0051] In some embodiments, such as Figure 2 As shown, the number of second support portions 212 in the support unit 21 is three. The other end of each second support portion 212 in the support unit 21 is connected to the other end of the second support portion 212 of an adjacent support unit 21. In this way, multiple support units 21 are interconnected to form a three-dimensional mesh structure. At this point, the support structure 20 can provide high support strength, ensuring the support effect. Of course, in some other embodiments, the other end of the second support portion 212 in the support unit 21 may not be connected to the other end of the second support portion 212 of an adjacent support unit 21.

[0052] In some embodiments, the mask body 10 includes a substrate. Sound transmission holes are formed on the substrate. The substrate is made of aluminum. Because the substrate is made of aluminum, it has high strength. Of course, the substrate can also be made of other materials. For example, the substrate can also be made of plastic, depending on the specific circumstances.

[0053] In some embodiments, the mask body 10 may further include a protective layer. The protective layer covers the surface of the substrate and serves to protect the substrate. In this way, the protective layer can protect the substrate and extend its service life.

[0054] In some embodiments, the protective layer can be an alumina layer. Alumina can form a dense protective film, providing better protection. Meanwhile, as mentioned above, the substrate can be made of metallic aluminum. In this case, when fabricating the protective layer, the substrate can be directly oxidized using an anodizing process to directly form the alumina layer, making the fabrication simpler and more convenient.

[0055] Furthermore, it is understood that the thickness of the mask body 10 can be designed according to actual conditions. For example, the thickness of the mask body 10 can be 0.4mm-0.6mm. For example, the thickness of the mask body 10 can be 0.4mm, 0.5mm or 0.6mm.

[0056] In some embodiments, the support structure 20 can be integrally formed by 3D printing. Manufacturing the support structure 20 using 3D printing is simpler and more convenient. Of course, in other embodiments, the support structure 20 can also be manufactured by other methods, depending on the specific circumstances.

[0057] In some embodiments, the surface of the mask body 10 may also be a rough surface. Specifically, the surface of the mask body 10 may be textured by a surface treatment process to make it more aesthetically pleasing.

[0058] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
