[0014] In existing technologies, the horn of most soundbars is molded as a single piece, inseparable from the enclosure. While this design provides structural stability, it severely limits the flexibility of acoustic design. Once the product is finalized, the soundbar's acoustic performance cannot be optimized and adjusted according to the user's actual listening environment or preferences due to physical space constraints. Furthermore, the integrated long horn also increases the difficulty and cost of product packaging and transportation.

[0015] This invention proposes a horn structure.

[0016] Please see Figures 1 to 4 As shown, in one embodiment of the present invention, the horn structure includes: a base component 100, an extension component 200, and a connecting assembly. The base component 100 is provided with a base horn 110, which has a first throat 111 and a first mouth 112. The first throat 111 is used to connect to the speaker unit 20. The extension component 200 is provided with an extension horn 210, which has a second throat 211 and a second mouth 212. The second throat 211 is sealed and connected to the first mouth 112, and the sound waves emitted by the speaker unit 20 are radiated to the outside from the second mouth 212. The connecting assembly connects the base component 100 and the extension component 200 respectively, and the base component 100 and the extension component 200 are detachably connected by the connecting assembly.

[0017] It should be noted that the base component 100 is fixedly installed on one end of the enclosure of the compatible speaker or other acoustic product. The base component 100 has a base horn 110 inside. It can be understood that the space between the base horn 110 and the outer wall of the base component 100 can be a slot or a solid structure, depending on the actual requirements. This embodiment does not impose any limitations.

[0018] The base horn 110 has a first throat 111 and a first opening 112, which are positioned opposite each other or extend to one side. The acoustic development curve of the base horn 110 can be exponential, hyperbolic, or any other suitable horn curve. The first throat 111 is used for a sealed connection with the output of the loudspeaker unit 20 to receive the sound waves it generates. In practice, the dimensions of the first throat 111 are matched with the diaphragm size or phase plug outlet of the loudspeaker unit 20. The extension member 200 is provided with an extension horn 210. The extension horn 210 has a second throat 211 and a second opening 212, which are positioned opposite each other or extend to one side. The development curve of the extension horn 210 smoothly connects with the base horn 110 to ensure the continuity of sound wave propagation and avoid impedance abrupt changes. In the specific implementation process, the shape and size of the second throat 211 can be precisely and acoustically sealed with the first opening 112 of the base component 100, so that there is no significant gap at the joint of the two components, so as to prevent sound energy leakage and unnecessary wind noise or distortion.

[0019] The connecting components connect the base component 100 and the extension component 200 respectively. For example, the connecting components can be fastening screws, which securely fix the base component 100 and the extension component 200 by tightening the screws. It is understood that the connecting components are not limited to threaded connections, but can also be snap-fit ​​connections, magnetic connections, or any mechanical structure that can achieve a stable and detachable connection.

[0020] This invention employs a base component 100 that is detachably connected to an extension component 200 via a connecting assembly. This allows the first opening 112 to mate with the first throat 111. Sound waves emitted by the speaker are transmitted through the base horn 110 to the extension horn 210 and radiate outwards through the second opening 212, thus extending the effective path of the horn and significantly reducing its effective low-frequency cutoff. Through a modular, detachable extension design, the physical space limitations of the horn structure are overcome. By detachably connecting the extension horn 210 to the base horn 110, acoustic products such as speakers adapted to the horn structure can achieve acoustic performance exceeding their original physical dimensions, particularly improving low-frequency efficiency and depth. Users can flexibly choose to install extension components 200 with different acoustic characteristics based on the size of the space, placement, and personal listening preferences, achieving "customized" acoustic performance. The detachable design of the base component 100 and the extension component 200 makes product packaging more compact, reducing the risk of damage during transportation and minimizing storage space. This enhances user experience, increases product added value, and improves market competitiveness.

[0021] In one embodiment, the horn structure further includes a matching connecting protrusion 120 and a connecting recess 220. One of the base member 100 and the extension member 200 is provided with the connecting protrusion 120, and the other of the two is provided with the connecting recess 220. The connecting protrusion 120 is adapted to be received in the connecting recess 220.

[0022] In specific implementation, the connecting protrusion 120 and the connecting recess 220 are respectively provided on the end faces of the mating ends of the base member 100 and the extension member 200. Specifically, the connecting protrusion 120 can be provided on the end face of the first opening 112 of the base member 100, and the connecting recess 220 can be correspondingly provided on the end face of the second throat 211 of the extension member 200; or, the opposite can be done, that is, the connecting recess 220 is provided on the base member 100, and the connecting protrusion 120 is provided on the extension member 200.

[0023] When the extension part 200 is assembled and connected with the base part 100, the connecting protrusion 120 can be precisely fitted and accommodated in the connecting recess 220, ensuring a sealed connection between the first opening 112 and the second throat 211. Thus, during assembly, the operator only needs to initially align the connecting protrusion 120 with the connecting recess 220 to achieve rapid and precise positioning and assembly of the base part 100 and the extension part 200 in the radial direction (i.e., in a plane perpendicular to the direction of sound wave propagation). This avoids potential misalignment or eccentricity of the two components during fastening, or excessive compression or extrusion from the groove due to component misalignment. It ensures that the acoustic central axes of the first opening 112 and the second throat 211 are strictly aligned, guaranteeing a stable and reliable acoustic seal and simplifying the assembly process.

[0024] Furthermore, the two surfaces of the connecting protrusion 120 and the connecting recess 220 that are opposite to each other are configured as inclined surfaces 230, and the two inclined surfaces 230 have the same inclination direction.

[0025] In the specific implementation, the end face of the connecting protrusion 120 facing the connecting recess 220 is an inclined surface 230, and correspondingly, the end face of the connecting recess 220 facing the connecting protrusion 120 is also an inclined surface 230. The two inclined surfaces 230 are adapted to each other and have the same inclination direction. Specifically, the inclined surface 230 is slightly inclined with a small inclination angle. As shown in the figure, the upper end of the inclined surface 230 is inclined towards the side closer to the base member 100, while the lower end is closer to the side closer to the extension member 200 than the upper end. Of course, the inclination direction can be specifically designed according to actual needs.

[0026] During assembly, when the connecting protrusion 120 begins to enter the connecting recess 220, the inclined surfaces in the same direction first come into contact, generating a centering force. As the insertion depth increases, the inclined surface 230 continuously guides the connecting protrusion 120 to slide into the most precise mating position of the connecting recess 220, achieving an automatic centering effect and greatly improving the convenience and accuracy of assembly. When the connecting protrusion 120 is pressed into the connecting recess 220 axially, the interaction of the inclined surfaces 230 is converted into a radial expansion or contraction force, which in turn causes the two parts to fit tightly in the radial direction, effectively eliminating mating gaps, improving the sealing between the base horn 110 and the extension horn 210, and preventing noise.

[0027] In one embodiment, the extension member 200 is provided in multiple ways, and the multiple extension horns 210 have different extension lengths in their length direction.

[0028] Understandably, the extension component 200 and the basic component 100 are detachably connected via a connecting assembly. The multiple extension horns 210 have different sizes, allowing for the replacement of the appropriate extension component 200 according to actual needs. Furthermore, the design can include extension components 200 with different acoustic development curves for the multiple extension horns 210, etc., which can be customized to meet the usage requirements in different environments.

[0029] The technical solution of this invention proposes a connection component with multiple structures. The basic component 100 and the extension component 200 are connected by the connection component, so that the basic horn 110 and the extension horn 210 are sealed and connected.

[0030] refer to Figure 5 and Figure 6 As shown, in one embodiment, the connecting component includes a first magnetic element 310 and a second magnetic element 320 that are magnetically connected to each other. The first magnetic element 310 is disposed on the base component 100, and the second magnetic element 320 is disposed on the extension component 200.

[0031] In practice, the first magnetic component 310 is glued or snapped onto the side of the base component 100 near the extension component 200, and is fixed inside the base component 310, such as by being embedded in the periphery of the first opening 112 of the base component 100. Correspondingly, the second magnetic wire is positioned opposite to the first magnetic component 310 and is glued or snapped onto one end near the base component 100, such as by being embedded in the periphery of the second throat 211 of the extension component 200. The magnetic poles of the first magnetic component 310 and the second magnetic component 320 are configured to generate a magnetic force that attracts each other when they are close together. One of them can be a permanent magnet (such as a neodymium iron boron magnet), and the other can be a permanent magnet with opposite polarity, or a magnetically conductive component made of a magnetically conductive material (such as iron or carbon steel) that can be attracted by magnetic force. When the extension component 200 is brought close to the base component 100, it can automatically achieve precise positioning and secure adsorption under the guidance of magnetic force. Disassembly is equally simple and direct. The assembly process is simplified, making it easier to replace different models of extension parts 200. Furthermore, the first magnetic component 310 and the second magnetic component 320 are evenly arranged, so that the magnetic attraction force is evenly distributed across the entire mating surface, which helps to ensure the sealing of the mating between the base horn 110 and the extension horn 210, and thus contributes to the acoustic sealing.

[0032] refer to Figure 7 and Figure 8 As shown, in another embodiment, the connecting component includes a groove 410 and a limiting boss 420 that are mutually adapted and slidably connected. The base member 100 has grooves 410 on its opposite sides, and the extension member 200 has limiting bosses 420 on its opposite side walls. The limiting bosses 420 are slidably connected in the grooves 410, so that the base member 100 is connected to the extension member 200.

[0033] In this embodiment, the limiting boss 420 is elongated, and both sides of the base component 100 are provided with limiting bosses 420, which extend vertically. The groove 410 is adapted to the limiting boss 420, and the base component 100 and the extension component 200 slide relative to each other in the vertical direction, allowing the limiting boss 420 to slide into the groove 410, thereby connecting the base component 100 and the extension component 200, and facilitating assembly. In specific implementation, this embodiment can cooperate with the magnetic component in the previous embodiment to form a composite connection system.

[0034] It should be further explained that, in this embodiment, the base component 100 is provided with a male connector protruding toward the extension component 200, and the end of the extension component 200 facing the base component 100 is recessed with a female connector adapted to the male connector. In specific implementation, the male connector can be adapted to the aforementioned connecting protrusion 120, and the female connector can be configured as the aforementioned connecting recess 220. Specifically, the limiting boss 420 is provided on both side walls of the female connector, and the groove 410 is provided on both side walls of the male connector. The extension component 200 slides up and down relative to the base component 100, so that the connecting limiting boss 420 slides into or out of the groove 410 to realize the assembly and disassembly of the extension component 200.

[0035] refer to Figure 9 and Figure 10 As shown, in another embodiment, the connecting component includes a locking member 500, an extension member 200 having a first through hole 510, a base member 100 having a second through hole 520, and the locking member 500 passing through the first through hole 510 and connected to the second through hole 520.

[0036] In this embodiment, the first through hole 510 and the second through hole 520 are arranged opposite to each other. The first through hole 510 can be a smooth hole or a threaded hole. One end of the locking member 500 passes through the first through hole 510 and is connected and fixed in the second through hole 520. In specific implementation, the locking member 500 (e.g., screw, bolt) can generate an axial locking force much stronger than that of a snap-fit ​​or magnetic attraction, tightly pressing the mating surfaces of the base member 100 and the extension member 200 together, ensuring the sealing between the base horn 110 and the extension horn 210, thereby achieving a highly reliable acoustic seal and effectively preventing airflow leakage sound during high sound pressure level operation. The locking member 500 can be a wing screw, etc., and can be installed without tools.

[0037] refer to Figure 11 and Figure 12 As shown, in another embodiment, the connecting component is configured as a pressing structure 600, with one of the extension member 200 and the base member 100 having the pressing structure 600, and the other of the two being adapted to snap into the pressing structure 600.

[0038] In this embodiment, the base component 100 and the extension component 200 are fixedly connected by a snap-fit ​​structure 600. It can be understood that the snap-fit ​​structure 600 can be installed on the base component 100, and the connection between the base component 100 and the extension component 200 is achieved through the snap-fit ​​connection of the snap-fit ​​structure 600; of course, the snap-fit ​​structure 600 can also be installed on the extension component 200, and the connection between the base component 100 and the extension component 200 is achieved through the snap-fit ​​connection of the snap-fit ​​structure 600. The snap-fit ​​structure 600 can be a snap-fit ​​structure that can be pressed and unlocked, or it can be a press-fastening structure, etc.

[0039] Further, this embodiment takes the installation of the pressing structure 600 on the base component 100 as an example. It is understood that the extension component 200 is provided with a slot 660, and the pressing structure 600 is adapted to and snapped into the slot 660. Specifically, the pressing structure 600 includes a pressing body 610, a reset component 620, and a latch 630. The pressing body 610 is disposed on the base component 100, and the latch 630 is connected to the pressing body 610. The base component 100 has a pressing slot 640 and a clearance slot. The pressing body 610 extends at least partially beyond the pressing slot 640. The latch 630 is movably disposed in the clearance slot and snaps into the extension component 200. The reset component 620 connects the pressing body 610 and the base component 100 respectively, and is used to drive the pressing body 610 to reset and keep the latch 630 snapped into the slot 660 of the extension component 200.

[0040] The pressing structure 600 is located inside the base component 100. The side wall of the base component 100 has a pressing groove 640 and a clearance groove. By pressing a portion of the pressing body 610 through the pressing groove 640, the pressing body 610 moves towards the base component 100, thereby disengaging the latch 630 from the extension component 200 and releasing the snap-fit ​​connection. The latch 630 is connected to the pressing body 610 (it can be integrally formed or assembled separately) and is movably disposed in the clearance groove, allowing it to extend or retract with the movement of the pressing body 610.

[0041] The reset element 620 is typically a compression spring, torsion spring, or elastic arm. Its two ends are connected to the internal structures of the pressing body 610 and the base component 100, respectively. When no external force is applied, the reset element 620 drives the pressing body 610 back to its initial position, keeping the latch 630 extended and engaging with the corresponding slot 660 on the extension component 200. When connecting the extension component 200 to the base component 100, the extension component 200 is aligned with the base component 100 and pushed in, causing the latch 630 to engage with the slot 660. When disassembly is required, the pressing body 610, exposed outside the pressing slot 640, is pressed inward. The pressing body 610 overcomes the force of the reset element 620 and moves inward, causing the latch 630 connected to it to retract from the slot 660 of the extension component 200 into the clearance slot. At this point, the snap-fit ​​constraint is released, and the extension part 200 can be easily separated from the base part 100.

[0042] In this embodiment, the base component 100 is provided with a baffle 650, and the pressing body 610 is provided with a pressing part 611. The pressing part 611 extends from the pressing groove 640 to the outside. The baffle 650 has a limiting hole. One end of the reset component 620 is provided in the limiting hole, and the other end is connected to the pressing body 610. Pressing the pressing part 611 causes the pressing body 610 to move toward the baffle 650 and squeeze the reset component 620, and causes the latch 630 to disengage from the extension component 200.

[0043] Within the base component 100, a fixed baffle 650 is provided. This baffle 650 serves as part of the internal framework of the base component 100, providing an installation position for the reset component 620. The pressing body 610 has a pressing part 611 extending from the pressing slot 640 to the outside of the base component 100 to facilitate pressing operations. The baffle 650 acts as a mechanical stop, defining its maximum pressing stroke together with the initial position of the pressing body 610. This prevents damage to the internal structure due to excessive pressing, ensuring the service life and reliability of the mechanism.

[0044] The reset element 620 is preferably a compression spring, with one end of the spring positioned within a limiting hole, and the other end connected to or abutting against the inner side of the pressing body 610. The limitation of one end of the reset element 620 within the limiting hole prevents radial displacement or buckling during operation, ensuring it is always compressed and released along a predetermined axial direction. This further ensures smoother and more stable movement of the pressing body 610 connected to the reset element 620, preventing jamming or tilting, thus improving the quality of the operating feel.

[0045] Specifically, when the pressing part 611 is pressed, the pressing body 610 moves towards the baffle 650, thereby directly compressing the reset member 620 located between it and the baffle 650. The linearly increasing reaction force generated when the reset member 620 is compressed is clearly transmitted to the user's finger through the pressing body 610, providing precise and forceful tactile feedback. After the pressing part 611 is released, the compressed reset member 620 pushes the pressing body 610 to accurately reset, and drives the latch 630 to reliably return to the locked position.

[0046] In the specific implementation, two sets of pressing structures 600 are provided, and the two sets of pressing structures 600 are symmetrically arranged. Furthermore, the two sets of pressing structures 600 are symmetrically arranged on the base component 100, and the two sets of pressing structures 600 are arranged 180 degrees symmetrically with respect to the acoustic central axis of the base horn 110. The two symmetrically arranged latches 630 can simultaneously apply equal and opposite locking forces to the extension component 200 at two symmetrical points. This balanced locking force ensures that the mating surfaces of the extension component 200 and the base component 100 are subjected to uniform force, thereby allowing the sealing ring between them to be compressed smoothly and evenly, greatly improving the reliability of the acoustic seal and effectively preventing potential leakage caused by uneven force on one side.

[0047] refer to Figure 13 and Figure 14 As shown, the present invention also proposes an audio product, which includes an audio body 10, a speaker unit 20, and a horn structure. The specific structure of the horn structure is as described in the above embodiments. Since this audio product adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The horn structure is connected to the audio body 10, and the speaker unit 20 is disposed on the audio body 10 and is positioned opposite to the first throat 111 of the basic horn 110.

[0048] In specific implementation, the audio product can be a soundbar or other types of speaker systems. The main body is typically a long strip structure used to house the circuit board, speaker unit 20, and other acoustic components. The speaker unit 20 serves as the sound source and is fixedly installed inside the main body 10. The horn structure adopts the structure described in any of the above embodiments, namely, it includes a detachably connected base component 100 and an extension component 200, which is installed at one end of the main body. The output end of the speaker unit 20 is precisely aligned and sealed with the first throat 111 of the base horn 110 of the horn structure. After the sound wave is generated by the speaker unit 20, it directly enters the first throat 111 and passes sequentially through the base horn 110, the docking interface, and the extension horn 210, finally radiating to the external space from the second opening 212 of the extension horn 210.

[0049] In one embodiment, the audio product further includes a positioning component, which includes a first positioning part 30 and a second positioning part 40 that are mutually adapted and plugged into each other. The first positioning part 30 is provided on one of the base component 100 and the audio body 10, and the second positioning part 40 is provided on the other.

[0050] The first positioning part 30 and the second positioning part 40 are respectively disposed on the base component 100 and the speaker body 10. Specifically, the first positioning part 30 can be disposed on the base component 100 and the second positioning part 40 can be disposed on the speaker body 10 accordingly; or, the opposite can be done. The first positioning part 30 and the second positioning part 40 can be configured as a matching positioning hole and positioning post structure, with the positioning post inserted into the positioning hole to achieve radial, or radial and axial positioning effects. Of course, other matching positioning structures, such as positioning buckles, can also be used, which will not be described in detail here.

[0051] By initially aligning the first positioning part 30 and the second positioning part 40, and pushing the base component 100 of the horn structure onto the speaker body 10, the horn structure can be precisely positioned radially within the body cavity, that is, in the direction perpendicular to the sound wave axis. This ensures that the output end of the speaker unit 20 is automatically and strictly aligned with the acoustic center axis of the first throat 111 of the horn, avoiding acoustic performance degradation caused by misalignment. Furthermore, this simplifies and speeds up assembly, reduces reliance on operator skills, and significantly improves production assembly efficiency and product consistency.

[0052] In one embodiment, the audio product further includes a grille 50, which is disposed at the end of the extension 200 of the horn structure opposite to the base component 100. Specifically, the grille 50 covers the outside of the second opening 212 of the extension 200. The grille 50 is typically made of metal. As a physical barrier, the grille 50 effectively prevents dust, insects, small particles, or other foreign objects from entering the horn interior or even the entire audio product cavity through the second opening 212, thereby maintaining the cleanliness of the speaker unit 20 and the inner wall of the horn and ensuring stable acoustic performance over long-term use. Furthermore, integrating the grille 50 into the port of the extension 200 allows for a more optimized acoustic fit between the grille 50 and the horn opening, minimizing interference with sound wave diffusion while ensuring effective protection.
