Description

Technical Field

[0001] This utility model relates to the field of coaxial speaker technology, and more specifically, to a seamless coaxial speaker structure based on surround optimization. Background Technology

[0002] A coaxial speaker is a loudspeaker technology that integrates the mid-bass driver and tweeter on the same axis. This coaxial layout achieves spatial consistency of the sound source, ensuring phase alignment between the mid-bass and tweeter. In traditional coaxial speaker designs, the mid-bass diaphragm surrounds the tweeter in a ring shape, each responsible for the acoustic conversion of low-frequency and high-frequency signals. To accommodate driver installation and diaphragm movement, a gap is typically present between the mid-bass diaphragm and the tweeter.

[0003] In traditional coaxial speaker design, a gap exists between the mid-bass diaphragm and the tweeter to meet the mechanical requirements of mid-bass diaphragm vibration and tweeter assembly, such as... Figure 1 As shown, this significantly affects the acoustic performance of the tweeter, with the following specific issues: First, the gaps cause geometric discontinuities on the surface of the mid-bass diaphragm, which disrupts the smoothness of high-frequency sound wave propagation from the center. When high-frequency sound waves encounter gaps during propagation, they are prone to diffraction and reflection, causing phase interference. This manifests as an uneven frequency response in the mid-to-high frequency range, with obvious peaks and troughs, thus reducing the clarity and resolution of the sound quality and affecting the representation of auditory details.

[0004] Secondly, the sound wave scattering caused by the gap exacerbates the acoustic interference between the tweeter and the mid-bass diaphragm. In the crossover frequency range, the sound waves from the tweeter and mid-bass driver overlap, and the presence of the gap leads to additional phase mismatch and nonlinear distortion. This not only weakens the acoustic synergy between the tweeter and mid-bass driver but may also produce "coloration" at specific frequency points, affecting the naturalness and balance of the sound.

[0005] Furthermore, in traditional coaxial speakers with a single-fold surround (R-ring) structure, a single-fold surround (R-ring) is connected between the tweeter housing and the mid-bass diaphragm body, such as... Figure 2 As shown, although the introduction of a surround improves some of the gap problem, its single surround design has limitations in terms of structural rigidity and geometric optimization. The single surround 1 still cannot completely eliminate the discontinuities between diaphragms in the high-frequency range (8kHz-20kHz), resulting in slight frequency response fluctuations and breakup vibrations. This causes some interference to the sound wave propagation of the tweeter, limiting dynamic response and acoustic coupling effects, making it difficult to meet the high requirements of high-fidelity audio systems and professional audio equipment for sound purity and detail reproduction. Utility Model Content

[0006] This invention aims to provide a seamless coaxial speaker structure based on surround optimization, in order to solve the problems of traditional coaxial speakers where there is no connecting structure between the bass diaphragm and the tweeter, which disrupts the smoothness of high-frequency sound wave propagation, causes acoustic interference due to gaps, and limits the dynamic response and acoustic coupling effect of the diaphragm in traditional single-surround coaxial speakers.

[0007] This utility model is achieved using the following technical solution: This utility model provides a seamless coaxial speaker structure based on surround optimization, including a mid-bass unit and a tweeter unit. The mid-bass unit is arranged in the circumferential direction of the tweeter unit. The tweeter unit includes a tweeter housing and a mid-bass diaphragm body. A connecting surround is provided between the tweeter housing and the mid-bass diaphragm body. The connecting surround is a ring-shaped structure, with its inner ring side connected to the tweeter housing and its outer ring side connected to the mid-bass diaphragm body. The connecting surround is bent radially to form at least two peak-shaped protrusions.

[0008] This invention uses a connecting ring to tightly connect the tweeter housing and the mid-bass diaphragm body, eliminating the annular gap between the mid-bass diaphragm and the tweeter unit. This improves the smoothness of high-frequency sound wave propagation, reduces sound wave interference, improves phase consistency, enhances waveguide function, and significantly improves acoustic performance. Furthermore, the connecting ring of this invention is bent radially to form at least two peak-shaped protrusions. Compared to the traditional single-ring, this increases the number of ring bends, reduces the ring height, and optimizes the ring geometry, resulting in better continuity of the mid-bass diaphragm, forming a continuous diaphragm surface, optimizing the dynamic response of the diaphragm, and improving the acoustic coupling effect between diaphragms.

[0009] As a preferred technical solution: The connecting fold is bent radially to form two peak-shaped protrusions, and the connecting fold is a double fold.

[0010] As a preferred technical solution: The cross-sectional shape of the two peak-shaped protrusions formed on the double-folded ring is M-shaped.

[0011] As a preferred technical solution: The mid-bass diaphragm body comprises a rigid layer and a flexible damping layer, which are arranged in layers and connected as one unit.

[0012] As a preferred technical solution: The flexible damping layer is disposed above the rigid layer.

[0013] As a preferred technical solution: The rigid layer is made of metal structural components, and the flexible damping layer is made of rubber structural components.

[0014] As a preferred technical solution: The connecting surround is bonded to the tweeter housing and the mid-bass diaphragm body.

[0015] As a preferred technical solution: The metal structural component is bonded to the rubber structural component.

[0016] As a preferred technical solution: The tweeter unit further includes a tweeter diaphragm, a tweeter U-shaped armature, a tweeter washer, a tweeter magnet, a tweeter voice coil, a tweeter voice coil frame, and a tweeter rear cavity. The tweeter U-shaped armature is mounted on the tweeter housing, the tweeter magnet is mounted on the tweeter U-shaped armature, the tweeter washer is mounted on the tweeter magnet, the tweeter voice coil frame is arranged in the ring direction of the tweeter washer, the tweeter voice coil is connected to the outer ring of the tweeter voice coil frame in the ring direction, the tweeter diaphragm is arranged above the tweeter voice coil frame and the tweeter housing, and the tweeter diaphragm is in contact with the tweeter voice coil frame and the tweeter housing. The tweeter rear cavity is located below the tweeter housing, and the tweeter rear cavity and the tweeter diaphragm are located on the upper and lower sides of the tweeter housing, respectively.

[0017] As a preferred technical solution: The mid-bass unit further includes a mid-bass diaphragm surround, a mid-bass bracket, a mid-bass spider, a mid-bass washer, a mid-bass magnet, a mid-bass T-iron, a mid-bass voice coil, and a mid-bass voice coil frame. The mid-bass diaphragm surround is connected between the mid-bass diaphragm body and the mid-bass bracket. The mid-bass voice coil frame is arranged in the ring-up position of the tweeter unit. The upper end of the mid-bass voice coil frame is connected to the rigid layer. The mid-bass spider is connected between the mid-bass voice coil frame and the mid-bass bracket. The mid-bass voice coil is connected to the outer ring of the mid-bass voice coil frame, which faces upwards. The mid-bass washer is located below the mid-bass bracket. The mid-bass magnet is located below the mid-bass washer and is placed on the mid-bass T-iron.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This utility model uses a connecting ring to tightly connect the tweeter housing and the mid-bass diaphragm body, eliminating the annular gap between the mid-bass diaphragm and the tweeter unit, improving the smoothness of high-frequency sound wave propagation, reducing sound wave interference, improving phase consistency, enhancing waveguide function, and significantly improving acoustic performance. Furthermore, the connecting ring of this utility model is bent radially to form at least two peak-shaped protrusions. Compared with the traditional single ring, this increases the number of ring bends, reduces the ring height, and optimizes the ring geometry, resulting in better continuity of the mid-bass diaphragm, forming a continuous diaphragm surface, optimizing the dynamic response of the diaphragm, and improving the acoustic coupling effect between diaphragms.

[0019] 2. This utility model designs the mid-bass diaphragm body as a composite structure including a rigid layer and a flexible damping layer, which optimizes the diaphragm performance. The composite structure takes into account both rigidity and flexibility, widens the frequency response range, makes the mid-low frequency performance more balanced, enhances the acoustic coupling effect and dynamic response between diaphragms, completely eliminates the discontinuity between diaphragms, and solves the acoustic defects of traditional coaxial speakers.

[0020] 3. Simulation results from COMSOL Multiphysics show that the double-loop design significantly smooths the frequency response curve in the mid-to-high frequency range (2kHz-20kHz), greatly reducing peaks and troughs.

[0021] In contrast, the unconnected structure exhibits significant peaks and troughs in the mid-to-high frequency range (especially 8kHz-15kHz) due to the annular gap; while the single-folded ring structure shows some improvement, it still exhibits slight fluctuations in the high frequency range (8kHz-20kHz).

[0022] The double-folded ring design of this invention effectively eliminates these fluctuations, reduces segmentation vibration and distortion, lowers acoustic interference and phase distortion, and enhances the function of the mid-bass unit as a high-frequency waveguide, resulting in purer sound quality and a wider dynamic range. It is suitable for various scenarios such as high-fidelity audio equipment and professional audio equipment. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1 like Figure 3 and Figure 4 As shown, this embodiment proposes a seamless coaxial speaker structure based on surround optimization, including a mid-bass unit and a tweeter unit. The mid-bass unit is arranged in the ring direction of the tweeter unit. The tweeter unit includes a tweeter housing 1, and the mid-bass unit includes a mid-bass diaphragm body 2. A connecting surround 18 is connected between the tweeter housing 1 and the mid-bass diaphragm body 2. The connecting surround 18 has a ring-shaped structure, with its inner ring side connected to the tweeter housing 1 and its outer ring side connected to the mid-bass diaphragm body 2. The connecting surround 18 is bent radially to form at least two peak-shaped protrusions.

[0032] The connecting ring 18 fills the gap between the mid-bass diaphragm and the tweeter, forming a continuous diaphragm surface.

[0033] Since the connecting ring 18 itself is a ring structure, the peak-shaped protrusion formed by bending it radially is also ring-shaped.

[0034] Preferably, the connecting fold 18 is bent radially to form two peak-shaped protrusions, and the connecting fold 18 is a double fold 18. The cross-sectional shape of the two peak-shaped protrusions on the double fold 18 is M-shaped, such as... Figure 4 As shown.

[0035] Preferably, the connecting ring 18 is bonded to the tweeter housing 1 and the mid-bass diaphragm body 2.

[0036] Preferably, the connecting fold 18 can be made of rubber, plastic, or the like.

[0037] This invention tightly connects the tweeter housing 1 and the mid-bass diaphragm body 2 through the connecting ring 18. Compared with the traditional single-ring (R-ring) structure and coaxial speakers without a connecting structure, it increases the number of ring bends and reduces the ring height, resulting in better continuity of the mid-bass diaphragm, improving the acoustic coupling effect between diaphragms, and completely eliminating the annular gap in traditional coaxial speakers, forming a continuous diaphragm surface.

[0038] Among them, the connecting ring 18 preferably adopts a double-fold ring design. The double-fold ring design optimizes the dynamic response of the diaphragm, improves the uniformity of diaphragm motion compared to a single-fold (R) ring, and significantly reduces the discontinuity between diaphragms compared to a non-connecting structure, ensuring the continuity of high-frequency sound wave propagation and the stability of waveguide effect.

[0039] Continuous diaphragm surfaces offer advantages such as reduced acoustic wave interference, improved phase coherence, and enhanced waveguide functionality. Specifically: Reduced acoustic interference: The continuous diaphragm surface avoids diffraction and reflection of high-frequency sound waves at the gaps, reducing phase interference, smoothing the frequency response curve in the mid-to-high frequency range, and improving sound clarity and resolution. The double-folded ring reduces minute acoustic disturbances through more uniform diaphragm movement, resulting in a purer high-frequency performance compared to a single-folded (R) ring; compared to a seamless structure, it completely eliminates the strong diffraction effect caused by the annular gaps.

[0040] Improved phase consistency: Eliminating gaps results in more unified phases between mid-low and high-frequency sound waves, reducing nonlinear distortion in the crossover frequency region and producing a more natural sound. The double-folded ring improves phase consistency in the mid-high frequency transition compared to a single-folded (R) ring by optimizing the dynamic synchronization between diaphragms; compared to a non-connected structure, it avoids distortion caused by phase mismatch between diaphragms.

[0041] Enhanced Waveguide Function: The continuous diaphragm surface acts as a waveguide for the tweeter, optimizing the directivity and diffusion of high-frequency sound waves and improving sound field width and spatiality. The double-ring design, by increasing the number of ring layers and optimizing geometry, significantly reduces the nonlinear deformation of the diaphragm, ensuring geometric consistency of the diaphragm surface as a waveguide, thereby improving the uniformity of high-frequency sound wave propagation and the precision of directional control. Compared to a single-ring (R) structure, the multi-layered structure of the double-ring further stabilizes the dynamic response of the diaphragm, reducing waveguide surface unevenness caused by diaphragm deformation, making high-frequency sound wave radiation more controllable and the sound field distribution more uniform. Compared to a seamless structure, the ringless design causes discontinuities on the diaphragm surface due to annular gaps, severely weakening the waveguide effect and causing directional disorder and sound field contraction in high-frequency sound waves. The double-ring, by forming a continuous and stable waveguide surface, significantly improves the diffusion and spatial performance of high-frequency sound waves.

[0042] Furthermore, frequency response curve simulation was used to verify: The simulation method is as follows: COMSOL Multiphysics software was used to simulate and analyze the frequency response curves of the traditional coaxial speaker (without connection structure, including gap), single-fold (R) ring design and the optimized design of this utility model (double-fold ring, without gap).

[0043] Simulation results (such as) Figure 5 (as shown) Traditional coaxial speakers (without a connecting structure): Due to the presence of annular gaps between the mid-bass diaphragm and the tweeter, the frequency response curve in the mid-high frequency range (2kHz-20kHz) fluctuates significantly, exhibiting obvious peaks and troughs. Especially in the 8kHz-15kHz range, the curve is not smooth, producing obvious peaks and troughs, resulting in a decrease in sound clarity.

[0044] Single-fold (R) ring design: By connecting with a single-fold (R) ring, some gaps are eliminated, and the frequency response curve is smoother than that of the unconnected structure, with fewer peaks and troughs. However, there are still slight fluctuations in the high-frequency range (8kHz-20kHz) due to acoustic disturbances caused by diaphragm deformation, resulting in insufficient curve flatness and affecting the stability and clarity of high-frequency sound quality.

[0045] The double-loop design of this invention eliminates gaps by connecting loop 18 (double loop), resulting in a significantly smoother frequency response curve with greatly reduced peaks and troughs. This is especially evident in the mid-to-high frequency range (2kHz-20kHz), where the curve exhibits greater flatness and a significantly smoother frequency response curve with greatly reduced peaks and troughs. This demonstrates that the optimized loop design of this invention effectively reduces sound wave interference and improves the clarity and naturalness of the sound quality.

[0046] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 3 and Figure 4 As shown, the mid-bass diaphragm body 2 includes a rigid layer 201 and a flexible damping layer 202, which are arranged in layers and connected as one unit.

[0047] The rigid layer 201 is used to provide high rigidity, ensuring fast response and sound resolution in the mid-frequency range; the flexible damping layer 202 is used to increase flexibility and damping characteristics, optimizing low-frequency extension and dynamic performance.

[0048] Preferably, the flexible damping layer 202 is disposed above the rigid layer 201.

[0049] Preferably, the rigid layer 201 is made of metal and the flexible damping layer 202 is made of rubber, and the two are bonded together.

[0050] Because the mid-bass diaphragm of traditional coaxial speakers is usually made of a single material (such as paper, plastic or metal), it is difficult to balance rigidity and flexibility, which limits the balance of frequency response and the dynamic performance of the diaphragm.

[0051] The mid-bass diaphragm body 2 of this utility model includes a rigid layer 201 and a flexible damping layer 202, which are composed of two rigid and flexible structures. The acoustic advantages are: the composite structure takes into account both rigidity and flexibility, widens the frequency response range, and makes the mid-low frequency performance more balanced.

[0052] The combination of metal and rubber reduces diaphragm breakup vibration, reduces distortion, and improves sound purity.

[0053] Compared to single-material diaphragms, composite diaphragms are more stable under high power input, making them suitable for various applications such as high-fidelity audio systems, car audio systems, and professional audio equipment.

[0054] Example 3 The difference between this embodiment and Embodiment 2 is as follows: like Figure 3 As shown, the tweeter unit further includes a tweeter diaphragm 3, a tweeter U-shaped armature 4, a tweeter washer 5, a tweeter magnet 6, a tweeter voice coil 7, a tweeter voice coil frame 8, and a tweeter rear cavity 9. The tweeter U-shaped armature 4 is mounted on the tweeter housing 1, the tweeter magnet 6 is mounted on the tweeter U-shaped armature 4, the tweeter washer 5 is mounted on the tweeter magnet 6, the tweeter voice coil frame 8 is arranged in the circumferential direction of the tweeter washer 5, the tweeter voice coil 7 is connected to the outer circumferential direction of the tweeter voice coil frame 8, the tweeter diaphragm 3 is arranged above the tweeter voice coil frame 8 and the tweeter housing 1, and the tweeter diaphragm 3 is in contact with the tweeter voice coil frame 8 and the tweeter housing 1. The tweeter rear cavity 9 is located below the tweeter housing 1, and the tweeter rear cavity 9 and the tweeter diaphragm 3 are located on the upper and lower sides of the tweeter housing 1, respectively.

[0055] The tweeter diaphragm 3 is used to generate high-frequency sound waves; the tweeter U-shaped iron 4, the tweeter washer 5, and the tweeter magnet 6 constitute a tweeter magnetic circuit system; the tweeter voice coil 7 and the tweeter voice coil skeleton 8 are used to drive the tweeter diaphragm 3 to vibrate; the tweeter rear cavity 9 can optimize the tweeter unit's resonance frequency by adjusting its volume, improve the high-frequency response, ensure clear and smooth sound quality, and effectively isolate external interference.

[0056] The mid-bass unit further includes a mid-bass diaphragm surround 10, a mid-bass bracket 11, a mid-bass spider 12, a mid-bass washer 13, a mid-bass magnet 14, a mid-bass T-iron 15, a mid-bass voice coil 16, and a mid-bass voice coil frame 17. The mid-bass diaphragm surround 10 is connected between the mid-bass diaphragm body 2 and the mid-bass bracket 11. The mid-bass voice coil frame 17 is arranged in the ring-up direction of the tweeter unit. The upper end of the mid-bass voice coil frame 17 is connected to the rigid layer 201. The mid-bass spider 12 is connected between the mid-bass voice coil frame 17 and the mid-bass bracket 11. The mid-bass voice coil 16 is connected to the outer ring-up direction of the mid-bass voice coil frame 17. The mid-bass washer 13 is placed below the mid-bass bracket 11. The mid-bass magnet 14 is placed below the mid-bass washer 13 and is placed on the mid-bass T-iron 15.

[0057] The mid-bass diaphragm surround 10 connects the mid-bass diaphragm body 2 to the mid-bass support 11, supporting diaphragm movement and maintaining a seal; the mid-bass support 11 provides structural support; the mid-bass spring 12 ensures the axial movement stability of the mid-bass voice coil 16 and reduces nonlinear distortion; the mid-bass washer 13, the mid-bass magnet 14, and the mid-bass T-iron 15 constitute a magnetic circuit system, providing a uniform magnetic field; the mid-bass voice coil 16 and the mid-bass voice coil frame 17 drive the mid-bass diaphragm body 2 to vibrate, generating mid-low frequency sound waves.

[0058] The working principle is as follows: For the mid-bass unit: The electrical signal generates electromagnetic force in the magnetic circuit system (mid-bass washer 13, mid-bass magnet 14, and mid-bass T-iron 15) through the mid-bass voice coil 16, driving the mid-bass diaphragm body 2 to vibrate and generate mid-low frequency sound waves. The connecting surround 18 ensures the continuity of the diaphragm surface.

[0059] For the tweeter: an electrical signal drives the tweeter diaphragm 3 to vibrate through the tweeter voice coil 7, generating high-frequency sound waves. The continuous diaphragm surface acts as a waveguide, optimizing the propagation characteristics of the high-frequency sound waves.

[0060] Collaborative operation: The connecting surround 18 integrates the mid-bass unit and the tweeter, while the composite mid-bass diaphragm body 2 enhances the frequency response, together reducing acoustic interference and optimizing the overall sound quality.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
