[0032] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0033] like Figures 1 to 3As shown, this utility model provides a high-frequency loudspeaker, including a high-frequency loudspeaker sound-emitting part 4 and a decorative shell. The decorative shell includes a decorative upper shell 1 and a decorative lower shell 2. The decorative upper shell 1 covers the top of the decorative lower shell 2. A first chamber 11 is provided inside the decorative upper shell 1, and a second chamber 21 is provided inside the decorative lower shell 2. The decorative upper shell 1 and the decorative lower shell 2 are connected by screw threads, so that the first chamber 11 and the second chamber 21 cooperate to form an accommodating cavity that matches the high-frequency loudspeaker sound-emitting part 4. The decorative upper shell 1 and the decorative lower shell 2 are combined to form a complete shell for protecting and decorating the sound-emitting part 4. Compared with the existing connection methods that use screws or adhesives, this utility model uses the decorative upper shell 1 and the decorative lower shell 2 to rotate and combine into one piece, forming a unified appearance. The product is more beautiful, and the tightness of the screw thread connection enhances the overall structural strength of the decorative shell, which can fully protect the high-frequency loudspeaker sound-emitting part 4, ensuring that the high-frequency loudspeaker sound-emitting part 4 is properly wrapped and protected, avoiding damage from the external environment.

[0034] It should be noted that the high-frequency loudspeaker sound-emitting part 4 can be a single loudspeaker or a complete unit composed of sound-emitting components in a loudspeaker. This utility model uses a single loudspeaker as an example for illustration, but is not limited thereto.

[0035] like Figure 3 , Figure 4 , Figure 6 As shown, in this embodiment, the upper decorative shell 1 is provided with an annular step 12 in the circumferential direction, and the side wall of the annular step 12 is provided with a first connecting thread 121. The side wall of the second chamber 21 of the lower decorative shell 2 is provided with a second connecting thread 211 in the circumferential direction. At least a portion of the annular step 12 is provided in the second chamber 21, and the first connecting thread 121 and the second connecting thread 211 are connected in a cooperative manner. During assembly, the annular step 12 of the upper decorative shell 1 is placed in the second chamber 21, and the upper decorative shell 1 is rotated so that its first connecting thread 121 and the second connecting thread 211 of the lower decorative shell 2 mesh with each other, thereby realizing the assembly and connection of the upper decorative shell 1 and the lower decorative shell 2. Compared with the traditional fastening, screw and adhesive connection, this utility model can increase the connection area between the upper decorative shell 1 and the lower decorative shell 2, thereby enhancing the stability of the connection and making the decorative shell less likely to loosen or fall off due to external force. At the same time, it also makes the disassembly and installation process of the upper decorative shell 1 and the lower decorative shell 2 simpler and faster, and improves the maintainability of the high frequency speaker sound-producing part 4 and the convenience of user operation.

[0036] like Figure 3 , Figure 4 , Figure 6As shown, in this embodiment, at least a portion of the annular step 12 is disposed within the second chamber 21 of the lower decorative housing 2, making the upper decorative housing 1 and the lower decorative housing 2 more tightly connected in the vertical direction, enhancing the overall structural strength of the decorative housing, and further preventing the decorative housing from falling off. Simultaneously, the annular step 12 can limit the high-frequency speaker sound-emitting part 4, preventing it from shaking within the accommodating cavity, thus providing further protection and improving assembly stability. Furthermore, the top of the lower decorative housing 2 abuts against the annular step 12, which can limit the upper decorative housing 1, preventing the annular step 12 from excessively entering the second chamber 21 of the lower decorative housing 2 during assembly, thereby avoiding structural damage or performance degradation due to improper assembly.

[0037] like Figures 3 to 4 As shown, in this embodiment, the sidewall thickness of the second chamber 21 is less than the width of the annular step 12 on the upper decorative housing 1, making it easier for the top of the lower decorative housing 2 to abut against the annular step 12. The width of the annular step 12 is greater than the sidewall thickness of the second chamber 21, providing a wider contact surface for the top of the lower decorative housing 2. This helps ensure that the lower decorative housing 2 can be accurately aligned and fixed on the annular step 12 during assembly, reducing assembly errors and improving the overall stability and reliability of the structure.

[0038] like Figure 1 , Figure 6 As shown, the outer side wall of the decorative lower shell 2 is provided with several grooves, which can increase the friction of the surface of the decorative lower shell 2, making it easier to assemble the decorative upper shell 1 and the decorative lower shell 2. At the same time, it also makes the decorative shell more beautiful and achieves a further decorative effect.

[0039] like Figure 1 , Figure 3 , Figure 5 As shown, in this embodiment, the decorative upper housing 1 is provided with an annular inclined surface 13, which is located above the annular step 12. This makes it easier to grasp and hold the decorative upper housing 1 when assembling the decorative lower housing 2, simplifying the assembly process and improving assembly efficiency. At the same time, the design of the annular inclined surface 13 gives the decorative upper housing 1 a unique visual effect, making the high-frequency speaker sound-emitting part 4 more attractive in appearance. This not only enriches the appearance style of the product but also enhances the overall texture and quality of the product.

[0040] like Figure 1 , Figure 3 , Figure 5As shown, in this embodiment, the top of the decorative upper housing 1 is provided with a mounting hole 14, which communicates with the first chamber 11, allowing the sound emitted by the high-frequency speaker 4 to propagate smoothly to the external environment, ensuring the clarity and penetration of the sound. Simultaneously, a mesh cover 3 is provided inside the mounting hole 14, which protects the high-frequency speaker 4 and prevents foreign objects from entering without affecting sound propagation. Specifically, an annular protrusion 15 is provided inside the first chamber 11 of the decorative upper housing 1, forming an annular mounting groove 16 between the annular protrusion 15 and the inner wall of the first chamber 11. The edge of the mesh cover 3 is positioned within the annular mounting groove 16, making the installation and removal of the mesh cover 3 simple and quick. Users can easily replace or maintain the mesh cover 3 without using complex tools or cumbersome steps, improving the maintainability of the product and the convenience of user operation.

[0041] like Figure 1 , Figure 3 , Figure 5 As shown, in this embodiment, the sidewall of the mounting hole 14 is provided with a guide slope 141, which allows the mesh cover 3 to slide more smoothly into the annular mounting groove 16 during installation. This eliminates the need for the user to forcefully squeeze or adjust the position of the mesh cover 3, simplifying the installation steps, reducing the installation difficulty, and also reducing the risk of damage or deformation of the mesh cover 3 due to improper installation.

[0042] like Figure 5 As shown, in this embodiment, the height of the annular protrusion 15 is less than the depth of the mounting hole 14, which makes it easier for the mesh cover 3 to pass through the mounting hole 14 and slide smoothly into the annular mounting groove 16 during installation, reducing friction and resistance during installation and making the installation process smoother and more efficient.

[0043] like Figure 1 , Figure 3 As shown, in this embodiment, the surface of the mesh cover 3 is curved, which helps to diffuse sound and allows it to spread more evenly to the surrounding environment. Furthermore, the protruding mounting hole 14 at the top of the mesh cover 3 allows sound to penetrate the mesh cover 3 more easily, reducing sound reflection and loss inside the mesh cover 3. In addition, the curved surface of the mesh cover 3 and the protruding mounting hole 14 at the top make the mesh cover 3 more visually appealing and attractive, enriching the product's appearance and enhancing its overall texture and quality.

[0044] like Figures 1 to 3As shown, in this embodiment, the mesh cover 3 includes multiple rows of staggered through holes 31, further enhancing sound penetration to facilitate the sound transmission of the high-frequency speaker 4, allowing the sound to travel more clearly over longer distances. Furthermore, the through holes 31 have a hexagonal cross-sectional shape. Compared to circular or other shapes, the hexagonal cross-section of the through holes 31 provides better structural stability and sound transmission characteristics, helping to reduce sound distortion during transmission and maintain the original sound quality. Of course, in actual design, the cross-sectional shape of the through holes 31 can be designed according to specific needs.
