Description

Technical Field

[0001] The utility model relates to the field of speaker grilles, in particular to a curved speaker grille and a mounting structure thereof. Background Art

[0002] Curved speaker grilles are a common feature, for example, they're often used on circular and oval speakers, and even polygonal speakers, often complementing the overall design. In the industry, curved speaker grilles are typically installed by extending mounting edges on the opposite side or around the curved grille, creating locking holes in the edges, and then threading screws through the holes into pre-threaded holes on the speaker body.

[0003] The above-mentioned installation method requires screws to be disassembled and assembled, which is cumbersome to operate. Moreover, the screw caps are exposed, affecting the aesthetic appearance of the speaker. Some also use a snap-on type, for example: CN209358757 U discloses an existing cylindrical speaker, which includes: a grille and a speaker body, the grille includes an elastic grille body of a cylindrical structure with openings at both ends, the grille body is provided with an expansion opening extending from one end opening to the other end opening on the curved side surface, and a first snap-on structure and a second snap-on structure are provided on the inner side of the grille body near the two sides of the expansion opening; the speaker body is a cylindrical structure, and a third snap-on structure that engages with the first snap-on structure and a fourth snap-on structure that engages with the second snap-on structure are provided on the curved cylindrical surface of the speaker body to fix the grille to the speaker body.

[0004] However, the grille covers a large area, essentially covering over 300 degrees of the speaker's circumference. For other existing cylindrical speaker products, promoting this snap-on mounting structure would require changes to the basic shape of the speaker body. This modification would increase mold and production costs, as well as the amount and cost of the grille material. The grille also obscures the speaker's exterior, resulting in a monotonous appearance.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0037] Please refer to Figures 1 to 13 As shown, it shows the specific structure of various embodiments of the present utility model.

[0038] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0039] like Figures 1 to 6 ,as well as Figure 9 As shown:

[0040] A curved speaker grille is made of an integrated metal material and includes a curved grille body 1. The middle portion of the curved grille body 1 is arched forward, and the left and right ends of the curved grille body 1 are extended backward so that the horizontal cross-section of the curved grille body 1 is C-shaped. The left end of the arc-shaped mesh cover body 1 is bent to the right to form a first folding piece 2, and the right end of the first folding piece 2 is bent backward to form a first embedding portion 3; the right end of the arc-shaped mesh cover body 1 is bent to the left to form a second folding piece 4, and the left end of the second folding piece 4 is bent backward to form a second embedding portion 5; the upper end of the arc-shaped mesh cover body 1 is bent backward to form a third folding piece 6, and the rear end of the third folding piece 6 is bent downward to form a fourth folding piece 7, and the fourth folding piece 7 is provided with a first positioning hole 8 that passes through the front and back, that is, the first positioning hole 8 passes through the front and rear ends of the fourth folding piece 7; the lower end of the arc-shaped mesh cover body 1 is bent backward to form a fifth folding piece, and the rear end of the fifth folding piece is bent upward to form a sixth folding piece, and the sixth folding piece is provided with a second positioning hole that passes through the front and back, that is, the second positioning hole passes through the front and rear ends of the sixth folding piece. The third folding piece portion 6 and the fifth folding piece portion can be one or more. Considering the difficulty and yield rate of bending processing, an intermittent design is generally adopted when multiple folding pieces are provided.

[0041] The first folding portion 2 and the second folding portion 4 are both vertically extending plates. Furthermore, each of the first and second mounting portions 3 and 5 is provided with a slot 9 extending therethrough. The first and second folding portions 2 and 4 can each be designed as a single, interconnected, elongated slot, or as two or more elongated slots spaced vertically apart. In other embodiments, one or more circular holes can also be used as slots. Generally, elongated slots are more tolerant of assembly errors during assembly.

[0042] To improve machining accuracy, the front surface of the curved mesh cover body 1 is provided with two shaping steps 10, one corresponding to the first folded tab 2 and the other to the second folded tab 4. The shaping steps 10 extend vertically. Each shaping step 10 is flush with the front end of the corresponding first folded tab 2 and second folded tab 4. The curved mesh cover body 1 is densely covered with small holes, but a long, non-porous area is reserved near the shaping steps 10, located in front of the shaping steps 10. The shaping step 10 is formed during the processing, and is limited to the long strip non-porous area by a jig, and a small gap is reserved on the outside of the corresponding parts of the first folding piece 2 and the second folding piece 4. When the first folding piece 2 and the second folding piece 4 are bent and formed, the plate is squeezed and deformed toward the aforementioned gap to form the shaping step 10. This is conducive to the precise forming of the first folding piece 2 and the second folding piece 4, and the subsequent bending and forming of the first embedded part 3 and the second embedded part 5 also adds a positioning reference, which better controls the bending and forming of the first embedded part 3 and the second embedded part 5. Moreover, the left and right ends after forming have better structural strength.

[0043] Next, a curved speaker grille installation structure is provided, comprising a curved speaker grille 100 and a speaker body 200, wherein the curved speaker grille 100 is installed on the front side of the speaker body 200;

[0044] The arc-shaped speaker grille is the arc-shaped speaker grille described above;

[0045] The front side of the speaker body is the speaker facing area. A left side embedding groove 12 is provided on the right side of the left side wall 11 of the speaker body, and a right side embedding groove 14 is provided on the left side of the right side wall 13 of the speaker body. An upper positioning protrusion is provided on the front side wall of the speaker body corresponding to the upper part of the speaker facing area, and a lower positioning protrusion is provided on the front side wall of the speaker body corresponding to the lower part of the speaker facing area. The speaker body includes a speaker shell and functional parts installed in the speaker shell (such as Figure 5 The speaker housing also includes an internal frame to facilitate the installation of the speaker, power supply, circuit board assembly, etc. The internal frame can also be used to form an integrated module with the various functional components within the speaker housing. During installation, the entire integrated module is placed within the speaker housing. The relative positioning of the internal frame and the speaker housing ensures that the various functional components are securely and reliably installed within the speaker housing. The left side wall 11 and the right side wall 13 of the speaker housing refer to the left and right walls of the speaker housing.

[0046] In the unassembled state, the left-right spacing between the first embedding portion 3 and the second embedding portion 5 is slightly larger than the spacing between the left embedding groove 12 and the right embedding groove 14. Specifically, the spacing between the left side of the first embedding portion 3 and the right side of the second embedding portion 5 is larger than the spacing between the inner left side of the left embedding groove 12 and the inner right side of the right embedding groove 14.

[0047] During assembly, pinch the left and right areas of the curved speaker grille with your hands to deform it (the left and right ends are slightly brought inward), and the first embedded part 3 at the left end and the second embedded part 5 at the right end are inserted into the corresponding left embedded groove and the right embedded groove. After release, under the self-rebound action of the curved speaker grille, the left and right ends are reset outward, and the first embedded part 3 is against the right side of the left wall, and the second embedded part 5 is against the left side of the right wall. At the same time, the first positioning hole 8 is nested and positioned correspondingly with the upper positioning boss, and the second positioning hole is nested and positioned correspondingly with the lower positioning boss. If the curved speaker grille needs to be disassembled for cleaning, pinch the left and right areas of the curved speaker grille with your hands to deform it (the left and right ends are slightly brought inward), release the pressure on the left and right walls of the speaker body, and pull it out.

[0048] The first embedded portion 3 and the second embedded portion 5 are both provided with a left-to-right through-slot 9; the right side of the left side wall of the speaker body and the left side of the right side wall are both convexly provided with a latch 15, and the latch 15 is located in the corresponding latch slot 9, further preventing the curved speaker grille from falling out forward. During assembly, pinch the left and right areas of the curved speaker grille with your hands to deform it (the left and right ends are slightly closer inward), and the first embedded part 3 at the left end and the second embedded part 5 at the right end are inserted into the corresponding left embedded groove and the right embedded groove. After releasing, under the self-rebound action of the curved speaker grille, the left and right ends are reset outward, and the first embedded part 3 is against the right side of the left wall, and the second embedded part 5 is against the left side of the right wall, and the slots are nested and positioned on the corresponding card protrusions. If the curved speaker grille needs to be disassembled and cleaned, pinch the left and right areas of the curved speaker grille with your hands to deform it (the left and right ends are slightly closer inward), release the pressure on the left and right walls of the speaker body, release the limit of the card protrusion on the card slot, and pull it out.

[0049] like Figure 7 and Figure 9As shown, a silicone ring 16 is provided between the curved speaker grille and the front side of the speaker body, and the first folded piece 2, the second folded piece 4, the fourth folded piece 7 and the sixth folded piece are pressed against the front side of the silicone ring 16. The provision of the silicone ring 16 can improve the assembly stability between the curved speaker grille and the speaker body, reduce the vibration generated by the speaker body during operation, especially reduce the vibration of the curved speaker grille relative to the speaker body, and avoid the loosening of the curved speaker grille due to long-term vibration. When selecting the silicone material, a silicone material with good heat dissipation can also be selected. In this way, the heat dissipation capacity of the speaker during operation can be improved to a certain extent. In addition, the silicone ring 16 can be designed with different surface convex and concave shapes and colors, which can be matched with the curved speaker grille to achieve a better decorative effect, making the appearance of the speaker more beautiful and diversified.

[0050] like Figure 8 and Figure 10 As shown, similarly, a silicone ring 16 is provided between the arc-shaped speaker grille and the front side of the speaker body, but the silicone ring 16 covers the front area of ​​the speaker body at the periphery of the arc-shaped speaker grille, and only a button area is reserved on the top. In this way, the visual effect of the front side of the speaker is relatively more affected by the silicone ring 16, and the front surface shape of the silicone ring 16 and the large area coverage present a different decorative effect.

[0051] like Figure 12 and Figure 13 As shown, this curved speaker grille 100 and speaker body 200 mounting structure is also applicable to cylindrical speaker products. The curved speaker grille 100 can have an arc angle of 180 degrees or less. There is no need to widen the curved speaker grille to wrap around the periphery of the speaker body to form a snap connection. Thus, the basic shape of the speaker body remains unchanged, and the curved speaker grille does not obscure the original shape of the speaker body. This avoids the increase in mold and production costs caused by changes to the speaker body's shape, and also reduces the amount of material used and the cost of the curved speaker grille.

[0052] The design focus of the present utility model is that it mainly utilizes the elasticity of the C-shaped structure of the arc-shaped mesh cover body 1 itself to embed the left and right ends into the speaker body to form abutment positioning. At the same time, the upper and lower ends are formed into a nested positioning by using punching holes and the convex columns reserved on the speaker body. In this way, when assembling, pinch the left and right areas of the arc-shaped speaker mesh cover with your hands, so that the left and right ends are slightly moved inward and inserted into the front side of the speaker body. After releasing, under the self-rebound action of the arc-shaped speaker mesh cover, the left and right ends are reset outward, the first embedded part 3 is against the right side of the left wall, and the second embedded part 5 is against the left side of the right wall. At the same time, the first positioning hole 8 is nested and positioned corresponding to the upper positioning convex column, and the second positioning hole is nested and positioned corresponding to the lower positioning convex column. The structure is simple and easy to operate, and there is no need to change the shape of the original speaker body too much.

[0053] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
