[0039] Figure 1 and Figure 2 Fig. shows the horn 10 in some embodiments of the present utility model, and the horn 10 is used to guide sound waves to propagate along a predetermined direction.

[0040] As Figures 1 to 4 shown, the horn 10 includes a guiding mechanism 1, an alignment mechanism 2 and a flow guiding mechanism 3. The alignment mechanism 2 and the flow guiding mechanism 3 are both arranged on the guiding mechanism 1. It can be understood that on the one hand, the guiding mechanism 1 is used to provide the space required for the installation of the remaining mechanisms, and on the other hand, it is also used to define, delimit or enclose a space, and guide the propagation of sound waves through this space. The alignment mechanism 2 plays a role in guiding the correct alignment and assembly of the guiding mechanism 1. The flow guiding mechanism 3 is used to further guide the sound waves propagating in the guiding mechanism 1.

[0041] As Figure 2 , Figure 3 and Figure 4 shown, the guiding mechanism 1 includes at least two guiding shells 11, and each guiding shell 11 is provided with a guiding surface 1111.

[0042] It can be understood that the guiding mechanism 1 is composed of at least two guiding shells 11. The outer contour shapes of these guiding shells 11 can be designed to be the same or different, specifically different according to the actual application requirements of the product. Each guiding shell 11 is provided with a guiding surface 1111, and the geometric shape and size of the guiding surface 1111 are carefully designed to achieve the best sound wave guiding effect.

[0043] It should be noted that the guiding surfaces 1111 are configured to be able to butt seamlessly to form a complete and uninterrupted sound wave guiding channel (such as the sound wave guiding cavity 4). The shape of the guiding surface 1111 can be linear, parabolic, exponential or any other curve that helps the uniform distribution and propagation of sound waves.

[0044] As Figure 3 and Figure 4 shown, the alignment mechanism 2 includes a number of alignment posts 21 and a number of alignment grooves 22. Each alignment post 21 and each alignment groove 22 are respectively arranged on each guiding shell 11, and the alignment posts 21 and the alignment grooves 22 are adapted to each other.

[0045] Understandably, the alignment post 21 is generally a columnar structure with a certain height, and its cross-sectional profile is adapted to the groove wall profile of the alignment groove 22. The protrusion amount of the alignment post 21 is equal to or less than the groove depth of the alignment groove 22, ensuring that the alignment post 21 can be completely inserted into the alignment groove 22, thereby avoiding the problem that the plane where the alignment mechanism 2 is located cannot fit. The position and number of the alignment posts 21 are determined according to the size and shape of the guiding shell 11 to provide sufficient support and alignment accuracy. Their design goal is to ensure that during the assembly process, the guiding shell 11 can be accurately docked according to the preset position and angle, greatly avoiding displacement deviation of the guiding shell 11 and ensuring the accurate docking of the guiding surface 1111, thereby ensuring the smooth transmission of sound waves.

[0046] As Figures 2 to 6 shown, the flow guiding mechanism 3 includes a number of flow guiding components 3a, and each flow guiding component 3a includes two flow guiding parts 31 and a first positioning part 32 and a second positioning part 33 respectively arranged on the two flow guiding parts 31. The two flow guiding parts 31 of each flow guiding component 3a are respectively arranged on the two guiding surfaces 1111.

[0047] Among them, each alignment post 21 is inserted into each alignment groove 22 one by one, so that the guiding surfaces 1111 jointly enclose a sound wave guiding cavity 4, and the edges of adjacent two guiding surfaces 1111 are aligned with each other. Also, each first positioning part 32 is aligned and cooperated with each second positioning part 33 one by one. Furthermore, the two flow guiding parts 31 of each flow guiding component 3a are aligned and abutted, and the peripheral side surfaces of the two flow guiding parts 31 are aligned with each other.

[0048] Understandably, each flow guiding component 3a includes two flow guiding parts 31, and the first positioning part 32 and the second positioning part 33 are respectively arranged on the two flow guiding parts 31 of the same flow guiding component 3a; that is, in the same flow guiding component 3a, the first positioning part 32 is arranged on one of the flow guiding parts 31, and the second positioning part 33 is arranged on the other flow guiding part 31. The first positioning part 32 and the second positioning part 33 are arranged to be aligned and cooperated with each other during assembly, so as to ensure the correct alignment connection between the flow guiding parts 31.

[0049] When the alignment posts 21 of the alignment mechanism 2 and the alignment grooves 22 are inserted into each other and the guiding shells 11 are accurately aligned, the guiding surfaces 1111 jointly form a closed sound wave guiding cavity 4. During this alignment and assembly process, the two flow guiding parts 31 of each flow guiding component 3a can be accurately aligned through the first positioning part 32 and the second positioning part 33. In this way, the edges of adjacent two guiding surfaces 1111 are aligned, and the peripheral side surfaces of the two flow guiding parts 31 of the flow guiding component 3a are aligned with each other, jointly forming a continuous and unbroken sound wave guiding cavity 4.

[0050] It should be noted that the positioning between the first positioning member 32 and the second positioning member 33 can be configured to be achieved through a positioning pin, a groove, a magnetic attraction interface or other forms of mechanical or physical positioning devices, and the purpose is to ensure the consistency and stability of the diversion portion 31 in the acoustic guiding cavity 4.

[0051] As Figures 1 to 5 shown, in some embodiments of the horn 10, the guiding mechanism 1 includes two guiding shells 11. The outer contour shapes of the two guiding shells 11 are the same. When the two guiding shells 11 are assembled in alignment through an alignment mechanism, the two guiding surfaces 1111 jointly enclose the acoustic guiding cavity 4.

[0052] It can be understood that the outer contour shapes of the two guiding shells 11 are the same, that is, they are completely consistent in terms of size, shape and structure. This design ensures the interchangeability between components and the convenience of assembly. When the two guiding shells 11 are assembled in alignment through an alignment mechanism, the guiding surfaces 1111 thereon can be seamlessly butted to jointly enclose an acoustic guiding cavity 4.

[0053] As Figures 3 to 6 shown, in some embodiments of the horn 10, the first positioning member 32 includes a positioning post 321, and the second positioning member 33 includes a positioning groove 331. The positioning post 321 is adapted to the positioning groove 331, and each positioning groove 331 is inserted into each positioning groove 331 in a one-to-one correspondence.

[0054] It can be understood that the positioning post 321 is a protruding structure, and its shape and size match those of the positioning groove 331. When the two diversion portions 31 need to be assembled together, the positioning post 321 can be accurately inserted into the positioning groove 331. In this way, not only a mechanical connection is provided, but also the relative positions of the two diversion portions 31 in the acoustic guiding cavity 4 are ensured to be accurate without error, avoiding the occurrence of steps or structures similar to steps at the contact positions of the two diversion portions 31 that should be aligned and fitted due to assembly deviation, and ensuring that the peripheral side walls of the two mutually contacting diversion portions 31 can form a smooth surface, so that sound waves can be transmitted smoothly.

[0055] As Figure 3 、 Figure 4 and Figure 6 shown, in some embodiments of the horn 10, a joint surface 311 is provided at the top of each diversion portion 31, and the first positioning member 32 or the second positioning member 33 is provided on each joint surface 311; when the first positioning member 32 and the second positioning member 33 are aligned and matched, the two joint surfaces 311 are aligned and fitted, and the edge contours of the two joint surfaces 311 on each diversion component 3a are aligned and fitted.

[0056] Understandably, the joint surface 311 is a plane where the flow guiding parts 31 contact each other. It provides a flat contact surface during the assembly of the flow guiding component 3a, avoiding the formation of a mating gap between the flow guiding parts 31 and preventing sound waves from entering between the two mutually contacting flow guiding parts 31 and generating unnecessary reflections or attenuations. The size and shape of the joint surface 311 match the geometric structure of the flow guiding part 31, ensuring that during the assembly process, the two joint surfaces 311 can be completely aligned and closely fitted.

[0057] When the first positioning member 32 and the second positioning member 33 are assembled, they are aligned with each other and closely cooperate to ensure the precise alignment between the flow guiding parts 31. When the first positioning member 32 is aligned and cooperates with the second positioning member 33, not only are the two joint surfaces 311 aligned and fitted, but also the edge contours of each are completely aligned. The peripheral side surfaces of the two mutually contacting flow guiding parts 31 form a continuous and gapless flow guiding interface, avoiding unnecessary refraction or attenuation of sound waves during transmission.

[0058] As Figure 5 shown, in some embodiments of the horn 10, the horn 10 includes two axially symmetric components 5. Each component 5 includes a guiding shell 11, at least one alignment post 21, at least one alignment groove 22, and at least two flow guiding parts 31. After the two components 5 are combined and connected through the alignment mechanism 2, they jointly enclose a sound wave guiding cavity 4.

[0059] Understandably, in this type of embodiment, the number of guiding shells 11 is two. The same number of alignment mechanisms 2 and flow guiding mechanisms 3 are provided on each guiding shell 11, and the installation positions of the alignment mechanisms 2 and the flow guiding mechanisms 3 on each guiding shell 11 are the same, so that the horn 10 can form two components 5 with the same structure. After the two components 5 with the same structure are assembled, they are axially symmetric to each other.

[0060] It should be noted that, first of all, since the two components 5 of the horn 10 are completely the same in structure, only one set of molds is needed to produce all the components required for the horn 10 during manufacturing, greatly saving the mold design and manufacturing costs. Secondly, the two components 5 do not distinguish between specific left and right parts, so that any two components 5 can be assembled to form the horn 10, improving the assembly production efficiency of the product.

[0061] As Figure 3 、 Figure 6 and Figure 7As shown, in some embodiments of the horn 10, each component 5 further includes a plurality of intermediate flow guiding portions 51, and each intermediate flow guiding portion 51 is located on the central axis L1 of the acoustic wave guiding cavity 4. An intermediate connection area 511 is provided on each intermediate flow guiding portion 51. A convex portion 512 is provided on half of the area of the intermediate connection area 511, and a groove 513 is provided on the other half of the area of the intermediate connection area 511. Each intermediate flow guiding portion 51 is configured to be aligned and abutted pairwise when the two guiding shells 11 are assembled in alignment, and each convex portion 512 is inserted into the groove 513 correspondingly one by one.

[0062] It can be understood that an intermediate connection area 511 is provided on the intermediate flow guiding portion 51. A convex portion 512 is configured on half of the area of this region, while a groove 513 is provided on the other half of the area. This design enables the intermediate flow guiding portion 51 to achieve pairwise alignment and abutment through the precise cooperation between the convex portion 512 and the groove 513 when the two guiding shells 11 are assembled in alignment, ensuring stable connection and precise alignment between the intermediate flow guiding portions 51.

[0063] When the two guiding shells 11 are assembled in alignment, the convex portion 512 on the intermediate flow guiding portion 51 can be accurately inserted into the groove 513 of another intermediate flow guiding portion 51. This mechanical alignment and connection method not only ensures the precise alignment between the intermediate flow guiding portions 51, but also greatly enhances the stability and integrity of the internal structure of the acoustic wave guiding cavity 4, avoiding the degradation of acoustic performance caused by assembly deviation.

[0064] It should be noted that through the content of this type of embodiment, it can be ensured that when any two components 5 are provided with intermediate flow guiding portions 51, there is still no need to distinguish the left and right assembly positions, that is, any two components 5 can still be assembled in alignment. Of course, there are also some embodiments of the horn 10 that do not require the setting of intermediate flow guiding portions 51, which are specifically adjusted according to the design structure and application requirements of the product.

[0065] As Figure 3 、 Figure 6 and Figure 7 shown, in some embodiments of the horn 10, an intermediate contact surface 514 is provided on each intermediate flow guiding portion 51, and an intermediate connection area 511 is provided on each intermediate contact surface 514;

[0066] When each intermediate flow guiding portion 51 is aligned and abutted pairwise, each intermediate contact surface 514 is aligned and attached pairwise, and the peripheral contour of each intermediate contact surface 514 is aligned with the peripheral contour of another intermediate contact surface 514, so that the peripheral side surface of each intermediate flow guiding portion 51 is aligned with the peripheral side surface of another intermediate flow guiding portion 51.

[0067] Understandably, the middle contact surface 514 is the key surface for the pairwise abutting and cooperation of the middle flow guiding parts 51. When the middle flow guiding parts 51 are pairwise aligned and abutted, the middle contact surface 514 can achieve precise fitting, which not only ensures the continuity of the sound wave propagation path, but also effectively reduces the reflection and scattering of sound waves during propagation, thereby improving the acoustic performance of the speaker.

[0068] The middle connection area 511 is located on the middle contact surface 514, and its design is to provide additional alignment and fixation when two middle flow guiding parts 51 are aligned. When the middle flow guiding parts 51 are pairwise aligned and abutted, the precise cooperation of the middle connection area 511 ensures that the peripheral contours of the middle contact surface 514 can be completely aligned, which means that the peripheral side surfaces of each middle flow guiding part 51 are aligned with the peripheral side surfaces of another middle flow guiding part 51, forming a continuous and unbroken sound wave guiding path. In this way, the efficient propagation of sound waves is further ensured, and the clarity and directivity of sound are improved.

[0069] Specifically, in some embodiments of the horn 10, the cross-section of the flow guiding part 31 is triangular, quadrilateral or circular.

[0070] Understandably, each flow guiding part 31 is columnar, and two flow guiding parts 31 can jointly form a columnar structure after being aligned and contacted. The flow guiding parts 31 with triangular cross-sections form a triangular prism after being pairwise aligned and cooperated, the flow guiding parts 31 with quadrilateral cross-sections form a quadrangular prism after being pairwise aligned and cooperated, and the flow guiding parts 31 with circular cross-sections form a cylinder after being pairwise aligned and cooperated.

[0071] Of course, the flow guiding part 31 can also be configured into other outer contour shapes that can perform the desired guiding or reflection of the sound wave transmission.

[0072] It should be noted that the outer shape of each flow guiding component 3a on the same horn 10 can be flexibly set after being assembled. For example, the sound wave guiding cavity 4 in a single horn 10 can simultaneously include a cylindrical flow guiding component 3a and a prismatic flow guiding component 3a.

[0073] As Figure 1 And Figure 2 Shown, in some embodiments of the horn 10, the sound wave guiding cavity 4 has an inlet 41 and an outlet 42, and the cross-sectional area of the sound wave guiding cavity 4 gradually increases along the direction from the inlet 41 to the outlet 42.

[0074] Understandably, along the sound wave transmission direction, the cross-sectional area of the sound wave guiding cavity 4 gradually increases, which can avoid the sound wave being always confined to a narrow space for transmission and prevent the reflection and absorption of the sound wave on the inner wall of the cavity. As the cross-sectional area of the sound wave guiding cavity 4 gradually increases, the sound wave can be more widely and evenly diffused, improving the uniformity of the sound field.

[0075] In some embodiments, each alignment post 21 is integrally formed on the guiding mechanism 1, and each flow guiding portion 31 is integrally formed on the guiding mechanism 1.

[0076] It can be understood that with the integral formation of the alignment post 21, the alignment post 21 will be integrally formed synchronously with the guiding housing 11 during the manufacturing process and become an inseparable part of the guiding housing 11. In this way, installation errors during the later installation of the alignment post 21 onto the guiding housing 11 can be avoided, thereby preventing excessive assembly errors between the guiding housings 11 due to the alignment post 21 with pre-existing setting errors. Similarly, the integral formation of the flow guiding portion 31 ensures a seamless connection between the flow guiding portion 31 and the guiding mechanism 1, reducing the degradation of acoustic performance caused by component loosening or displacement. Of course, the integral formation setting method can also improve the connection strength between components and enhance the durability of the product.

[0077] The loudspeaker of the present utility model includes a housing, a sound generating unit, and a horn 10. The sound generating unit and the horn 10 are both arranged on the housing. The housing serves to protect the internal components from the external environment. The sound generating unit is the core component that generates sound. It can be a moving coil type, a flat type, or other types of driving units, and is responsible for converting electrical signals into sound waves. The horn 10 serves as a sound guide and is responsible for optimizing the sound waves generated by the sound generating unit.

[0078] Implementing the present utility model has the following beneficial effects:

[0079] The present utility model relates to a horn and a loudspeaker, and a horn is arranged on the loudspeaker. On the one hand, through the setting of the alignment mechanism, precise alignment between the guiding housings is ensured, avoiding misalignment of the guiding surfaces on the guiding housings, that is, ensuring that the edges of each guiding surface can be aligned with the edges of the adjacent guiding surface, improving the flatness of the inner wall surface of the sound wave guiding cavity. On the other hand, based on the cooperation between the alignment post and the alignment groove, further through the precise docking of the first positioning member and the second positioning member on the flow guiding assembly, the flow guiding portions can be closely aligned, avoiding the formation of steps at the contact position between the two flow guiding portions.

[0080] In summary, when the sound wave is transmitted in the sound wave guiding cavity, whether it contacts the inner wall surface of the sound wave guiding cavity or the flow guiding portion, it can effectively prevent non-ideal reflection and interference caused by the stepped structure or misalignment of the mating surface, thereby improving the high-frequency response and the clarity of the sound.
