Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and in particular to a loudspeaker cone, a loudspeaker and a vehicle. Background Art

[0002] The cone in a speaker is a key component that converts electrical signals into mechanical vibrations. The pressure changes caused by these vibrations form sound waves in the surrounding air, which produces sound. Therefore, the material selection of the speaker cone is extremely important.

[0003] With the development of vehicles, more and more users are paying attention to the visual effects of car interiors and the effects of car audio. However, existing car speakers generally use dark materials or hidden settings, which makes the visual effects of the speakers not prominent enough. Even if more speakers are arranged in the vehicle, it is difficult for users to find them at the first time. In addition, since the general shape of the speakers is fixed and it is difficult to effectively match them with the vehicle interior, many speakers add decorative outer cover structures to enhance the visual effects. However, this will increase the manufacturing cost of the speakers. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a speaker cone, a speaker and a vehicle to enhance the speaker effect.

[0005] In order to achieve the above-mentioned and other related purposes, the utility model provides a speaker cone, comprising:

[0006] A cone group, wherein the outer side surface of the cone group is a reflective surface, and the reflective surface has an undulating texture structure.

[0007] In a specific embodiment of the present invention, the cone group includes:

[0008] A first basin layer, wherein the first basin layer is an electroplated metal layer, the reflective surface is an outer side surface of the first basin layer, and the first basin layer is located at the outermost side of the sound basin group;

[0009] A second basin layer is stacked on the inner side of the first basin layer.

[0010] In a specific embodiment of the present invention, the second basin layer is made of Kevlar fiber.

[0011] In a specific embodiment of the present invention, the textured structure is a woven texture.

[0012] In a specific embodiment of the present invention, metallic silver is electroplated on the outer side of the second basin layer to form the first basin layer.

[0013] In a specific embodiment of the present invention, a third basin layer is further included, and the first basin layer, the second basin layer and the third basin layer are stacked in sequence from the outside to the inside.

[0014] In a specific embodiment of the present invention, the third basin layer is made of damping glue or reinforcing glue.

[0015] In a specific embodiment of the present invention, the first basin layer, the second basin layer and the third basin layer are all annular cone structures, and the outer edge and inner edge of the first basin layer are aligned with the outer edges and inner edges of the second basin layer and the third basin layer.

[0016] The utility model also includes a loudspeaker, comprising the loudspeaker cone as described above.

[0017] The utility model also includes a vehicle, comprising the loudspeaker as described above.

[0018] The utility model proposes a speaker cone, a speaker and a vehicle, wherein the outer side surface of the speaker cone is set to a bright surface, so that when an ambient light is used in the vehicle, the outer side surface of the speaker cone can reflect the light of the ambient light, and at the same time, since the reflective surface has a texture structure, the reflected light will be more dispersed to avoid affecting the driver's eyes. The light reflected by the speaker cone will also produce a fluctuating effect with the vibration of the cone, further improving the overall visual effect of the speaker. In addition, the use of Kevlar material can enhance the overall structural strength of the cone, and the damping glue can enhance the internal damping of the speaker cone, thereby improving the playback effect of the speaker.

DETAILED DESCRIPTION

[0023] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. During actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0025] At present, the visual effects of car speakers are not prominent enough, and users may not immediately recognize the location and existence of the speakers, which may reduce the user's overall experience of the car audio system. Especially for those users who have high expectations for the sound effects. Since existing car speakers generally use dark materials or hidden settings, it is difficult to effectively integrate them with the vehicle interior. This may cause the speakers to appear abrupt or uncoordinated in the interior, affecting the overall design and aesthetic effect. In the highly competitive automotive market, the design and visual effects of car speakers are crucial to consumers' purchasing decisions. If the visual effects of car speakers are not prominent, it may affect the sales and market competitiveness of the vehicle model, especially under the consumer trend of pursuing personalization and high-end.

[0026] Since the general shape of speakers is fixed and difficult to effectively match with the vehicle interior, many speakers add decorative outer cover structures to enhance the visual effect. Adding an outer cover structure may affect the vibration effect of the sound cone, thereby affecting the sound quality. The outer cover structure may hinder the free propagation of vibrations, causing sound attenuation or distortion. Designing and manufacturing the outer cover structure increases costs. This includes not only the cost of materials, but also the cost of processing and labor. If the outer cover structure needs to be customized to fit a specific vehicle interior, the cost may increase further.

[0027] The utility model provides a speaker cone, comprising:

[0028] The cone group, the outer side surface of the cone group is a reflective surface, and the reflective surface has an undulating textured structure. The cone group 10 is an annular cone structure. It can also be considered that the cone group 10 is a cone bowl structure as a whole. Among them, the outer side of the cone group refers to the side facing the speaker, which can be understood as the side facing the sound wave emission. The cone group 10 with an annular cone structure has better rigidity. The design of the annular structure can improve the stability of the cone during vibration, reduce distortion and reproduce sound more accurately. Among them, the reflective surface refers to a surface that has a reflective effect in the human eye, which is usually achieved by using specific materials or treatment methods. For example, mirrors, water surfaces, shiny metal surfaces, etc. are the most common reflective surfaces.

[0029] Reflective surfaces and surface textures can enhance the quality and modern feel of the interior of the car. This design can make the interior look more refined and high-end, improving the comfort and satisfaction of users.

[0030] Designing the outer side of the speaker cone to be bright can well reflect the ambient light in the vehicle, creating a soft and comfortable atmosphere in the car. This design can make the lighting effect in the car more uniform and increase the comfort of passengers. The reflective surface has a textured structure to make the reflected light more dispersed, avoiding the impact of direct light on the driver's vision. This design not only maintains the visual effect, but also takes into account driving safety. When the speaker cone reflects light, it produces a fluctuating effect as the cone vibrates. This visual dynamic effect may increase the fun and vitality of the atmosphere in the car, bringing a richer sensory experience to the passengers in the car. This design not only improves the functionality of the audio system, but also adds a unique charm to the decoration and atmosphere creation in the car. This innovative design can attract consumers' attention and enhance the overall value and attractiveness of the vehicle.

[0031] like Figure 1 As shown, the cone group 10 includes a first cone layer 11 and a second cone layer 12:

[0032] The first basin layer 11 is an electroplated metal layer, and the reflective surface is the outer side of the first basin layer 11. The first basin layer 11 is located at the outermost side of the sound basin group 10. The electroplated metal layer usually has a smooth and bright surface with good reflectivity and conductivity. Through the electroplated metal layer, the sound basin group 10 can achieve a good appearance effect and enhance the ability to reflect light, making it easier for light to be reflected and transmitted.

[0033] The second basin layer 12 is stacked on the inner side of the first basin layer 11. The second basin layer 12 is used to provide structural support, acoustic adjustment or protection. The materials that can be used include plastic, fiber material or other synthetic materials. The presence of the second basin layer 12 can increase the stability and durability of the sound cone group 10 and help optimize the acoustic performance.

[0034] In a specific embodiment of the present invention, the second basin layer 12 is made of Kevlar fiber. Kevlar, formerly known as KEVLAR in English, is also translated as Kevlar or Kevlar. It is a brand name of an aramid fiber material product. The original name of the material is "poly(p-phenylene terephthalamide)", and the repeating unit of the chemical formula is -[-CO-C6H4-CONH-C6H4-NH-]-. The amide group connected to the benzene ring is a para structure.

[0035] At present, the cone-shaped cone of the traditional speaker can vibrate in a relatively rigid manner in the low-frequency area within the audio range of 20 Hz to 20 kHz that can be heard by the human ear, so there will be lower distortion. However, the inertial force generated at high frequencies is larger, making it impossible for the cone of the general vibrator to maintain consistent rigidity during vibration, thus causing distortion in sound reproduction.

[0036] Kevlar fiber has very high strength and durability, and is lighter and stronger than other fiber materials, such as glass fiber or carbon fiber. In this way, the second basin layer 12 can provide excellent structural support while protecting the sound cone group 10 from external impact or vibration. Kevlar fiber has excellent acoustic properties and can effectively control vibration and resonance, thereby improving the acoustic performance of the sound cone. It can help the sound cone group 10 produce clearer and more accurate sound, providing a better listening experience.

[0037] In a specific embodiment of the present invention, the textured structure is a woven texture. Woven textures generally have a complex and unique appearance, which can increase the visual appeal of the cone assembly 10. Compared with a traditional smooth surface, the woven texture structure can give the cone assembly 10 a more dynamic and modern feel, making it more prominent in the interior decoration of the vehicle. The woven texture structure can produce subtle light and shadow effects when reflecting light, further enhancing the visual effect. This structure can make the reflected light softer and more uniform, creating a more comfortable and warm atmosphere in the vehicle.

[0038] In a specific embodiment of the utility model, metallic silver is electroplated on the outer side surface of the second basin layer 12 to form the first basin layer 11. Using electroplated metallic silver as the woven texture on the outer side surface of the second basin layer 12 can avoid the use of additional processing steps to simulate the woven texture, thereby saving costs. By utilizing the texture and structural characteristics of the Kevlar fiber itself, combined with the appearance and reflective properties of electroplated metallic silver, a dual effect in design is achieved, which not only reduces manufacturing costs but also maintains the beauty and functionality of the design. Such a design cleverly utilizes the characteristics of the material itself, avoids complex processing technology, simplifies the manufacturing process, and ensures the appearance texture and performance requirements of the product. This cost-saving design strategy is quite common in the automotive industry and can effectively improve production efficiency and competitiveness.

[0039] like Figure 1 As shown, the third basin layer 13 is also included, and the first basin layer 11, the second basin layer 12 and the third basin layer 13 are stacked in sequence from the outside to the inside. By stacking the three basin layers in sequence, the overall structural stability of the sound cone group 10 can be enhanced. The material properties and structural design of each layer can complement and strengthen each other, so that the sound cone group 10 can better resist vibration and external pressure. The material and texture design of each layer will affect the acoustic performance of the sound cone group 10. By changing the characteristics of each layer, the propagation and reflection of sound can be optimized, and the clarity and accuracy of sound quality can be improved.

[0040] In a specific embodiment of the utility model, the third basin layer 13 is made of damping glue. Conventional Kevlar woven materials have poor internal damping, and the overall listening experience and distortion suppression are slightly insufficient. Therefore, after adding appropriate damping glue as the third basin layer 13, after the original excellent hardness and lightness characteristics, the sound diffusion will be more stable, the sound expression will be more natural, thick and prominent, and the sound reproduction, separation and resolution of the music sound effects will be improved. Damping glue can effectively absorb the energy of vibration and sound, thereby reducing the reflection and echo of sound, making the sound diffusion more stable. This helps to improve the propagation effect and balance of music and sound effects in the car environment.

[0041] In a specific embodiment of the present invention, the third basin layer 13 is made of reinforced glue. The reinforced glue can enhance the structural strength and stability of the entire sound cone group 10. It can effectively resist vibration and pressure, thereby reducing the risk of sound distortion and material damage. The reinforced glue can help control the diffusion and propagation of sound. It can reduce the echo and reflection of sound, making the sound quality clearer and more balanced.

[0042] like Figure 1As shown, the first basin layer 11, the second basin layer 12 and the third basin layer 13 are all annular cone structures, and the outer edge and inner edge of the first basin layer 11 are aligned with the outer edge and inner edge of the second basin layer 12 and the third basin layer 13. The annular cone structure can effectively guide and conduct sound waves, so that the sound can be transmitted from the speaker cone more effectively. That is, the first basin layer 11, the second basin layer 12 and the third basin layer 13 have the same shape and size and can cover each other. Since the three basin layers have the same shape and size, their vibration characteristics and acoustic characteristics will also be more consistent. This can ensure that the sound quality of the speaker in different frequency ranges is more balanced and consistent, avoiding timbre distortion or uneven frequency response caused by mismatched vibration characteristics. The same shape and size of the cone layers means that they can be manufactured using the same mold and process, thereby simplifying the manufacturing process and improving production efficiency. In addition, since they can cover each other, the assembly process will be easier. When the three cone layers of the same shape and size are aligned, their structure will be more stable. This consistency helps reduce deformation or distortion that may occur due to vibration, improving the structural stability and reliability of the speaker.

[0043] like Figure 2 As shown, the utility model also includes a speaker, including the speaker cone as described above, and also includes:

[0044] The dust cap 14 is used to cover the middle part of the sound cone.

[0045] The basin frame 20 is a structural frame for placing and supporting the sound cone assembly 10. It is usually a metal or plastic frame that can firmly fix the sound cone assembly and provide support and protection. The basin frame 20 can also assume the function of transmitting and distributing part of the sound vibration.

[0046] The voice coil 30 is a coil wound on a bracket, which is controlled by current to generate a magnetic field and interacts with the magnet (main magnet 70) to generate sound.

[0047] The support piece 40 is an elastic element connecting the voice coil 30 and the basin frame 20, and is used to support and position the voice coil 30 to ensure its accurate movement in the magnetic field.

[0048] The magnetic conductive sheet 50 and the magnetic conductive bowl 60 together with the main magnetic steel 70 constitute a magnetic circuit system for concentrating and guiding the magnetic field so that it interacts with the voice coil 30 to generate sound.

[0049] The main magnet 70 and the auxiliary magnet 71 are usually strong magnets that generate a magnetic field, which interacts with the voice coil 30 to generate a force, causing the sound cone to vibrate and produce sound.

[0050] The soldering piece 80 is usually used to connect the wires of the voice coil 30 to an external connector or cable. The soldering piece 80 is usually a small piece of metal, one end of which is connected to the lead on the voice coil 30, and the other end is used to connect to an external circuit or cable.

[0051] The utility model also includes a vehicle, comprising the above-mentioned loudspeaker. The vehicle is not only a means of transportation, but also a mobile music space, providing a comfortable environment for passengers to enjoy high-quality music.

[0052] To sum up, the utility model proposes a speaker cone, a speaker and a vehicle, in which the outer side surface of the speaker cone is set to a bright surface, so that when the ambient light is used in the vehicle, the outer side surface of the speaker cone can reflect the light of the ambient light. At the same time, since the reflective surface has a texture structure, the reflected light will be more dispersed to avoid affecting the driver's eyes. The light reflected by the speaker cone will also produce a fluctuating effect with the vibration of the cone, further enhancing the overall visual effect of the speaker. In addition, the use of Kevlar material can enhance the overall structural strength of the cone, and the damping glue can enhance the internal damping of the speaker cone, thereby enhancing the playback effect of the speaker.
