Description

Technical Field

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

[0002] In existing dynamic woofer technology, due to inherent physical characteristics, the cone will generate reverse resonance around the mid-frequency (800Hz), which impairs the speaker's sound performance in this frequency range.

[0003] Currently, the common approach to addressing this issue is to use materials with better damping, such as butyl rubber instead of nitrile rubber. Butyl rubber, with its high damping properties, can absorb the energy of the cone's anti-phase resonance, thereby improving speaker performance. However, this method significantly increases material costs. Summary of the Invention

The thickness of the folded ring is greater than the thickness of the cone. The outer side of the cone is provided with a flange, which corresponds to the position of the annular cavity of the folded ring and extends away from the annular cavity.

[0006] According to one embodiment of the present invention, the cone includes a central connecting portion, a sounding portion, and an outer peripheral connecting portion connected in sequence. The cross-section of the sounding portion is arc-shaped, and the cross-section of the outer peripheral connecting portion is straight. The central connecting portion is connected to the voice coil, and the outer peripheral connecting portion is bonded to the folded ring. The flange is located on the outer peripheral side of the outer peripheral connecting portion.

[0007] According to one embodiment of the present invention, the central connecting portion is provided with an inwardly protruding flange, the flange being embedded in the voice coil and conforming to the inner wall of the voice coil.

[0008] According to one embodiment of the present invention, the material of the folded ring is different from that of the cone; the cone is made of carbon fiber, while the folded ring is made of non-metallic material.

[0009] According to one embodiment of the invention, the thickness of the cone is 0.25 mm to 0.45 mm, and the thickness of the fold is 0.5 mm to 0.7 mm.

[0010] According to one embodiment of the present invention, the angle between the flange and the axis of the cone assembly is 30-50 degrees; and / or the length of the flange is 1-3 mm.

[0011] According to one embodiment of the present invention, a chamfer is provided at the connection between the flange and the cone, and the radius of the chamfer is 0.3 to 0.5 mm.

[0012] According to one embodiment of the present invention, the basin frame assembly further includes an iron frame, a magnet, a washer, a basin frame body, and a spring. The inner side of the basin frame body is connected to the iron frame, and the outer side of the basin frame body is connected to the outer side of the folding ring. The magnet and the washer are sequentially installed above the iron frame. The voice coil is sleeved on the magnet and connected to the cone. The voice coil and the magnet are slidably engaged. The spring is disposed between the voice coil and the basin frame.

[0013] The technical solution adopted to achieve the purpose of this application is as follows: In the second aspect of this application, the present invention also discloses a vehicle that includes the speaker described in the first aspect above.

[0014] According to one embodiment of the present invention, a connecting shell is provided on the vehicle body, the connecting shell having a first snap-fit ​​portion and a deformable portion connected to the first snap-fit ​​portion; the frame assembly has a second snap-fit ​​portion, the second snap-fit ​​portion having a first guide surface and a second guide surface in opposite directions; during the assembly of the speaker with the connecting shell in a first posture, the first snap-fit ​​portion moves along the first guide surface to snap the speaker with the connecting shell; during the assembly of the speaker with the connecting shell in a second posture, the first snap-fit ​​portion moves along the second guide surface to snap the speaker with the connecting shell.

[0015] As can be seen from the above technical solution, the loudspeaker disclosed in this application includes a frame assembly and a cone assembly. The cone assembly includes a surround and a cone.

This allows the sound to radiate more concentratedly forward, thereby improving the loudspeaker's directivity and enhancing sound propagation. The single flange design reduces material usage and processing difficulty while ensuring performance improvement, lowering the loudspeaker's manufacturing cost. Adding a flange to the cone also increases the overall structural strength of the cone. Since the thickness of the surround is greater than the thickness of the cone, the structural strength of the surround is compatible with the structural strength of the cone, thus improving the overall structural strength of the cone assembly.

Detailed Implementation

[0020] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0023] In related technologies, the phenomenon of reverse resonance of the speaker cone around the mid-frequency range (800Hz) has many adverse effects. Specifically, the speaker's frequency response curve exhibits large peaks and valleys at this location, leading to uneven sound output at different frequencies. Some frequencies are too loud, while others are too weak, severely affecting sound fidelity. Simultaneously, total harmonic distortion (THD) increases sharply in this frequency band, forming spikes and causing the speaker output to contain a large amount of distortion components, resulting in noise.

[0024] Therefore, embodiments of the present invention disclose a loudspeaker and a vehicle that can effectively suppress the reverse resonance of the cone at the mid-frequency position without significantly increasing costs, improve the frequency response curve and total harmonic distortion of the loudspeaker, and enhance sound performance.

[0025] The technical solutions of this application will be described in detail below through specific embodiments and in conjunction with the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized manner, by way of example and not limitation.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In a first aspect embodiment of this application, a loudspeaker 1000 is disclosed, which includes a frame assembly 100 and a cone assembly 200. The cone assembly 200 includes a surround 210 and a cone 220. The outer side of the surround 210 is connected to the frame assembly 100, the inner side of the surround 210 is connected to the outer side of the cone 220, and the inner side of the cone 220 is connected to the voice coil 110 of the frame assembly 100. The thickness of the surround 210 is greater than the thickness of the cone 220. A flange 221 is provided on the outer side of the cone 220. The flange 221 corresponds to the annular cavity of the surround 210 and extends away from the annular cavity.

[0027] The loudspeaker 1000 disclosed in this embodiment adds a flange 221 to the cone 220. During the vibration of the loudspeaker 1000, the flange 221 can adjust the vibration characteristics of the edge of the cone 220, suppress unnecessary vibration harmonics, guide and reflect sound to a certain extent, reduce the scattering and interference of sound during propagation, and make the sound radiate forward more concentratedly, thereby improving the directivity of the loudspeaker 1000 and enhancing the sound propagation effect.

[0028] When the speaker 1000 emits sound, the cone assembly 200 undergoes high-frequency reciprocating motion. The thicker surround 210 effectively resists the deformation caused by the high-frequency reciprocating motion of the cone assembly 200, ensuring the overall structural stability of the cone assembly 200, reducing distortion caused by structural deformation, and further improving sound fidelity. Adding a flange 221 to the cone 220 further increases the overall structural strength of the cone 220. Since the thickness of the surround 210 is greater than the thickness of the cone 220, the structural strength of the surround 210 is compatible with that of the cone 220, thereby enhancing the overall structural strength of the cone assembly 200.

[0029] The single-flanged 221 design reduces material usage and processing difficulty while ensuring improved performance, thus lowering the manufacturing cost of the speaker 1000.

[0030] In one embodiment, the loop 210 includes a first connecting portion 211, a bent portion 212, and a second connecting portion 213 arranged sequentially. The cross-sections of both the first connecting portion 211 and the second connecting portion 213 are straight, while the cross-section of the bent portion 212 is arc-shaped to form a ring cavity. The central angle corresponding to the bent portion 212 is less than 180 degrees. This specific arc design can precisely control the direction of sound propagation. Compared to traditional designs, it allows sound to radiate more concentratedly forward, reducing sound scattering in other directions, thereby improving sound directivity.

[0031] The second connecting portion 213 is angled relative to the first connecting portion 211. With the bottom of the first connecting portion 211 as a reference, the second connecting portion 213 tilts downwards, and its end is flush with or slightly higher than the bottom of the first connecting portion 211. The first connecting portion 211 is connected to the frame assembly 100, and the second connecting portion 213 is connected to the cone. This tilted structure ensures that the stress on the surround 210 is more uniform during cone vibration, avoiding nonlinear distortion caused by localized stress concentration. The cone can more smoothly and accurately follow the vibration of the voice coil 110, thereby reducing harmonic distortion and intermodulation distortion.

[0032] In one embodiment, the basin frame assembly 100 further includes a metal frame 120, a magnet 130, a washer 140, a basin frame body 150, and a spring 160. The metal frame 120 is W-shaped, with its center lower than its edge to form a mounting cavity. The W-shaped metal frame 120 helps to guide and enhance the magnetic field, reduce magnetic field leakage, and thus improve the strength and uniformity of the magnetic field.

[0033] Magnet 130 and washer 140 are sequentially mounted above iron frame 120. Both magnet 130 and washer 140 are located within the mounting cavity, and are spaced apart from the inner wall of the mounting cavity. The top surface of magnet 130 is lower than the outer edge of iron frame 120, while the top surface of washer 140 is level with or slightly higher than the outer edge of iron frame 120. This height difference design further optimizes the magnetic circuit structure. It can better control the direction and distribution of the magnetic field, allowing the magnetic field to form a more ideal magnetic gap in the area where voice coil 110 is located. This ensures that voice coil 110 can efficiently cut magnetic field lines within the magnetic gap, generating sufficient electromotive force, thereby improving the sensitivity and energy conversion efficiency of loudspeaker 1000.

[0034] The top of the voice coil 110 is connected to the cone 220, and the bottom of the voice coil 110 is fitted over the magnet 130, with the bottom of the voice coil 110 located between the inner wall of the iron frame 120 and the magnet 130. The voice coil 110 and the magnet 130 are in sliding engagement. When the frame assembly 100 is connected to AC power, the voice coil 110 moves up and down along the axis of the iron frame 120. The spider 160 is disposed between the voice coil 110 and the frame. When the voice coil 110 moves up and down, it drives the cone 220 to move up and down synchronously, which in turn drives the spider 160 to vibrate, thereby producing sound.

[0035] The basin stand body 150 is generally conical, with its top considered as the outer side and its bottom as the inner side. The lower diameter of the basin stand body 150 is smaller and it is connected to the outer wall of the iron frame 120. The top diameter of the basin stand body 150 is larger and it is connected to the first connecting part 211 of the folding ring 210.

[0036] The magnetic circuit system consists of an iron frame 120, a magnet 130, and a washer 140; the vibration system consists of a voice coil 110, a cone body, and a spider 160; and the frame body 150 serves as a support system. The magnetic circuit system provides magnetic force. When alternating current is applied to the voice coil 110, under the influence of the Lorentz force, the voice coil 110 moves up and down in the gap between the magnet 130 and the iron frame 120, simultaneously driving the entire vibration system to reciprocate up and down, thereby causing the cone body to vibrate and produce sound.

[0037] In one embodiment, the cone 220 includes a central connecting portion 222, a sounding portion 223, and an outer peripheral connecting portion 224 connected in sequence. The central connecting portion 222 is connected to the voice coil 110. The sounding portion 223 has an arc-shaped cross-section and is slightly convex outward. When the cone vibrates, the sounding portion 223 is the main sound-producing structure. This shape design allows the sounding portion 223 to more effectively push air when vibrating. The outer peripheral connecting portion 224 is bonded to the second connecting portion 213 of the fold ring 210, and the cross-section of the outer peripheral connecting portion 224 is straight. The straight structure provides a larger bonding area, making the bond between the outer peripheral connecting portion 224 and the second connecting portion 213 more secure. The flange 221 is located on the outer periphery of the outer peripheral connecting portion 224, and the length of the outer peripheral connecting portion 224 is equal to the length of the second connecting portion 213, so that the flange 221 begins to turn at the connection between the second connecting portion 213 and the bend 212.

[0038] In one embodiment, the length L of the flange 221 is 1-3 mm, and the end of the flange 221 is flush with or higher than the end of the second connecting portion 213, so that the flange 221 is within the range of the annular cavity and does not exceed the range of the annular cavity.

[0039] When the length of the flange 221 is within this range, the vibration characteristics of the cone 220 edge can be effectively adjusted without significantly increasing material usage and overall weight, suppressing unnecessary vibration harmonics. Furthermore, the flange 221 can effectively enhance the local strength of the cone 220 edge. During the operation of the loudspeaker 1000, the cone 220 needs to withstand alternating stress caused by the vibration of the voice coil 110. The presence of the flange 221 can disperse these stresses, reducing the risk of deformation or damage to the cone 220 edge due to stress concentration.

[0040] By keeping the flange 221 within the annular cavity and not exceeding it, unnecessary gaps can be effectively avoided between the flange 221 and other components of the speaker 1000 (such as the frame body 150). During sound propagation, gaps can lead to sound leakage, reducing the output sound pressure level and sound efficiency of the speaker 1000. A well-designed flange 221 can seal off any potential sound leakage paths, allowing the sound to radiate more concentratedly forward, improving sound propagation and the speaker 1000's sound production efficiency.

[0041] During use, the speaker 1000 may be affected by environmental factors such as temperature and humidity, causing the material to expand or contract. By controlling the length and position of the flange 221 within a reasonable range, the cone 220 can maintain an appropriate gap and fit with the surrounding structure. Even under different environmental conditions, interference or jamming caused by material deformation can be avoided, thus improving the product's environmental adaptability and reliability.

[0042] In one embodiment, the angle α between the flange 221 and the axis of the cone assembly 200 is 30-50 degrees. For example, the angle α between the flange 221 and the axis of the cone assembly 200 can be set to values ​​such as 30 degrees, 40 degrees, and 50 degrees. A suitable flange 221 angle can improve the acoustic radiation characteristics of the cone assembly 200. During sound propagation, the flange 221 can have a certain influence on the direction and distribution of sound propagation. An angle design of 30-50 degrees can make the sound radiate forward more evenly, reduce sound reflection and interference, improve sound clarity and directivity, thereby improving the overall sound performance of the loudspeaker 1000.

[0043] Furthermore, when the angle is too small, the friction and adhesion between the flange 221 and the mold will increase, leading to difficulties in demolding and potentially causing damage to the flange 221 or mold wear, increasing production costs and cycle time. When the angle α is too large, although the length of the flange 221 will increase, the increase in structural strength is not significant, and it will instead waste materials, increasing the weight and cost of the product. An angle design of 30-50 degrees can reasonably control the length of the flange 221 and the amount of material used while ensuring structural strength, achieving a balance between structural strength and material cost, and reducing costs.

[0044] In one embodiment, the central connecting portion 222 is provided with an inwardly protruding flange, which is embedded in the voice coil 110 and fits against the inner wall of the voice coil 110. Specifically, the middle portion of the central connecting portion 222 is an outwardly protruding curved surface, and its edge portion is provided with an inwardly protruding flange. The outer diameter of the flange is substantially equal to the inner diameter of the voice coil 110, so that the flange can be engaged in the voice coil 110, thereby realizing the connection between the central connecting portion 222 and the voice coil 110. The sound-producing portion 223 is connected to the top of the flange, and when the central connecting portion 222 is connected to the voice coil 110, the top of the voice coil 110 abuts against the connection between the central connecting portion 222 and the sound-producing portion 223.

[0045] In one embodiment, the material of the fold 210 is different from that of the cone 220; the cone 220 is made of carbon fiber, while the fold 210 is made of non-metallic material.

[0046] As the main sound-generating component of the loudspeaker 1000, the cone 220, made of carbon fiber, offers numerous advantages. Carbon fiber's high strength and low density allow the cone 220 to respond more quickly and accurately to the voice coil 110 during vibration, reducing the impact of its own inertia on vibration. This reduces sound distortion, resulting in clearer, purer sound and a more faithful reproduction of audio signals. Simultaneously, the excellent rigidity of carbon fiber helps the cone 220 maintain a stable shape during vibration, preventing unnecessary sound coloration due to deformation and improving sound quality.

[0047] However, carbon fiber is expensive, while the surround 210 is only used to connect the cone to the frame body 150. It only needs to ensure the cone can vibrate flexibly. Therefore, the requirements for the material of the surround 210 are relatively low. The surround 210 can be made of lower-cost materials, such as PET (polyethylene terephthalate) or TPU (thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber). These materials have good elasticity and flexibility, providing appropriate elastic support for the cone 220, allowing it to move freely within the vibration range, while effectively limiting excessive vibration and ensuring vibration stability and controllability. By using relatively low-cost non-metallic materials such as PET or TPU, the surround 210 effectively reduces material costs without affecting the basic performance of the speaker 1000.

[0048] The processing of carbon fiber requires specific equipment and technology, making the process relatively complex and costly. In contrast, the processing technology for non-metallic materials such as PET or TPU is relatively mature and simple, and common molding methods such as injection molding and extrusion can be used, reducing processing difficulty and cost, and further controlling the overall cost of the product.

[0049] In one embodiment, the thickness of the cone 220 is between 0.25 mm and 0.45 mm. As the main sound-generating component of the loudspeaker 1000, the thickness of the cone 220 has a significant impact on its vibration characteristics. The thickness range of 0.25 mm to 0.45 mm gives the cone 220 appropriate rigidity and flexibility. A cone 220 that is too thin may lack rigidity and easily deform excessively during vibration, leading to sound distortion; while a cone 220 that is too thick is too rigid, resulting in insufficient vibration response and affecting the clarity and detail of the sound.

[0050] The thickness of the surround 210 is 0.5 mm to 0.7 mm. It provides suitable elasticity to help the cone 220 vibrate stably at different frequencies, reduce fluctuations in frequency response, and make the frequency band transition of the sound more natural and smooth.

[0051] For example, in one embodiment, the thickness of the cone 220 can be set to 0.35 mm, and the thickness of the fold 210 can be set to 0.6 mm. This appropriate thickness difference effectively enhances the structural strength of the connection between the cone 220 and the fold 210, creating a reasonable stress distribution at the connection and preventing stress concentration at the connection due to identical thicknesses. The relatively thicker portion of the fold 210 can better withstand and disperse the stress from the vibration of the cone 220, enhancing the strength and stability of the connection and reducing the risk of breakage or damage at the connection point.

[0052] The thickness difference between the cone 220 and the surround 210 should not be too large or too small. It can be controlled within 0.8 mm to 1.2 mm. This thickness difference range ensures that the speaker 1000 has good sound performance and structural strength without significantly increasing costs due to excessive pursuit of performance. If the thickness difference is too large, it may lead to uncoordinated vibrations between the two components, affecting structural stability; if the thickness difference is too small, it may not be able to fully utilize the material properties of each component, reducing structural strength.

[0053] By selecting appropriate thickness ranges for the cone 220 and surround 210 while ensuring sound performance and structural strength, the amount of material used can be reasonably controlled. Excessively thick cones 220 and surrounds 210 will increase material costs, while excessively thinner ones may fail to meet performance requirements. A cone 220 thickness of 0.25 mm to 0.45 mm and a surround 210 thickness of 0.5 mm to 0.7 mm satisfies performance requirements while avoiding material waste and reducing product material costs.

[0054] In one embodiment, a chamfer is provided at the connection between the flange 221 and the cone 220, and the radius of the chamfer is 0.3 to 0.5 mm.

[0055] The chamfer creates a smoother transition area at the connection between the flange 221 and the cone 220. This transition area avoids sharp edges at the connection, reducing stress concentration. Stress concentration is a major factor leading to structural failure. By setting a suitable chamfer, stress can be distributed more evenly at the connection, thereby enhancing the structural strength of this part and improving the ability of the cone assembly 200 to withstand external forces.

[0056] The size of the chamfer is mainly determined by the manufacturing process of the cone assembly 200. Under the condition that conditions permit, the smaller the chamfer, the more obvious the increase in structural strength.

[0057] Through the above embodiments, this application has the following beneficial effects or advantages: The loudspeaker 1000 disclosed in this application significantly strengthens the structural strength of the cone 220 and the surround 210 at the bonding point by adding a flange 221 to the cone 220. When the cone resonates in opposite phase at around 800Hz, the flange 221 can also effectively resist the stress generated by the resonance, thereby greatly reducing the opposite phase resonance phenomenon of the cone 220 at this position. At the same time, the design that the thickness of the surround 210 is greater than the thickness of the cone 220 further suppresses the occurrence of opposite phase resonance from a structural perspective. With these two measures combined, the problem of severe opposite phase resonance in the prior art is effectively solved.

[0058] Based on the same inventive concept, a second aspect of this application discloses a vehicle that includes the speaker 1000 disclosed in any of the first aspects of the above-described embodiments.

[0059] The vehicle disclosed in this application includes the aforementioned speaker 1000. By providing a flange 221 on the cone of the speaker 1000, the vehicle can achieve better sound quality with minimal additional cost.

[0060] See Figure 5 and Figure 6 In one embodiment, a connecting shell 2000 is provided on the vehicle body. The connecting shell 2000 has a first snap-fit ​​portion 2100 and a deformable portion connected to the first snap-fit ​​portion 2100. The frame assembly 100 has a second snap-fit ​​portion 1100, which has a first guide surface and a second guide surface with opposite directions.

[0061] During the assembly of the speaker 1000 with the connecting shell 2000 in a first posture, the first snap-fit ​​part 2100 moves along the first guide surface to snap the speaker 1000 with the connecting shell 2000; during the assembly of the speaker 1000 with the connecting shell 2000 in a second posture, the first snap-fit ​​part 2100 moves along the second guide surface to snap the speaker 1000 with the connecting shell 2000.

[0062] The connecting shell 2000 is provided with a first snap-fit ​​portion 2100 and a deformable portion, and the frame assembly 100 is provided with a second snap-fit ​​portion 1100 having a first guide surface and a second guide surface with opposite directions. When installing the speaker 1000, regardless of whether it is in the first or second position, simply moving the first snap-fit ​​portion 2100 along the corresponding guide surface and using the elastic deformation of the deformable portion can easily achieve snap-fit ​​without complicated tools or cumbersome steps.

[0063] The interior space of a vehicle is complex, and the installation position and orientation of the speaker 1000 may vary depending on the vehicle model and design requirements. This design, through different guide surfaces and orientations, can flexibly adapt to different installation scenarios and directional needs. By precisely controlling the installation orientation of the speaker 1000, it is possible to avoid the speaker 1000 facing obstructions such as seats or interior panels after installation. When the speaker 1000 is facing the appropriate direction, the sound can be transmitted more directly into the vehicle interior, reducing energy loss and sound quality degradation caused by sound reflection and absorption by obstructions, resulting in clearer and louder sound.
