[0046] like Figure 1 and Figure 2 and combine when necessary Figures 3 to 10 The speaker grille assembly 100 in this embodiment includes a speaker grille 20 and a mounting bracket 30, wherein the mounting bracket 30 is used to install and fix the speaker grille 20. The speaker grille 20 in this embodiment includes:

[0047] The main body of the net 21 has multiple horn holes 212;

[0048] The first sidewall 23 is connected to the edge of the first side 21a of the net body 21, and the inner surface 232 of the first sidewall 23 is provided with a hidden buckle part 238.

[0049] The second sidewall 25 is connected to the edge of the second side 21b of the net body 21, and a fastener 26 is provided on the second sidewall 25.

[0050] In some products containing speaker grilles 20 (e.g., mobile phones, laptops, tablets, display devices, or televisions), the outer surface 215 of the grille body 21 and a portion of the sidewalls (e.g., the first sidewall 23) are exposed in a relatively conspicuous position and easily observed by the user, while another portion of the sidewalls (e.g., the second sidewall 25) is in a relatively concealed position and is not easily noticed by the user. By providing snap-fit ​​structures (a hidden snap-fit ​​part 238 on the first sidewall 23 and a snap-fit ​​part 26 on the second sidewall 25) on the two sidewalls (the first sidewall 23 and the second sidewall 25), it can be ensured that the speaker grille 20 can be stably and securely installed in the corresponding position of the product. In addition, the inner surface of the sidewall exposed in a relatively conspicuous position (e.g., the first sidewall 23) and the sidewall located in a relatively concealed position (e.g., the second sidewall 25) cannot be observed by the user during use. By placing the two snap-fit ​​structures for stable installation in the aforementioned positions that cannot be observed by the user, the snap-fit ​​structures can be avoided from affecting the aesthetics of the product. Therefore, the aforementioned speaker grille 20 can achieve a stable installation without compromising the product's aesthetic appearance.

[0051] Correspondingly, the mounting bracket 30 for installing the speaker grille 20 may include a frame 32, on which a first mating part 323 is provided to cooperate with the concealed snap-fit ​​part 238 and a second mating part 325 to cooperate with the snap-fit ​​member 26. After the speaker grille 20 is placed in a predetermined position, the concealed snap-fit ​​part 238 and the snap-fit ​​member 26 on it will respectively engage with the first mating part 323 and the second mating part 325 on the mounting bracket 30 to achieve fixation and installation between the speaker grille 20 and the mounting bracket 30.

[0052] For larger electronic devices such as flat-screen TVs and display panels, the speaker grille 20 and speaker grille assembly 100 are typically installed at the lower part of the device. In this scenario, the first sidewall 23 can be installed on the top side (the upper side of the speaker grille 20), which is a relatively conspicuous position; the second sidewall 25 can be installed on the bottom side (the lower side of the speaker grille 20), which is a relatively concealed position and will not be easily noticed by the user.

[0053] In specific implementations, the concealed snap-fit ​​part 238 can be various types of snap-fit ​​structures, such as snap blocks, snap slots, or snap hooks, as long as they can be hidden on the inner surface of the sidewall. In this embodiment, the concealed snap-fit ​​part 238 is a snap slot 238, and the snap slot 238 is formed by a recess in the inner surface 232 of the first sidewall 23. Correspondingly, the first mating part 323 is a protrusion 323 that engages with the snap slot 238. In the above embodiment, since the snap slot 238 is hidden within the inner surface 232 of the first sidewall 23, the snap-fit ​​structure (snap slot 238 and protrusion 323) can be effectively prevented from being exposed.

[0054] Furthermore, the slot 238 may include a bottom wall 2381 and multiple side walls 2383 connected to the bottom wall 2381, forming a receiving space. During installation, the corresponding structure (protrusion 323) on the mounting bracket 30 is inserted into the receiving space of the slot 238, achieving positioning and locking at that location. The presence of the bottom wall 2381 prevents the slot 238 from penetrating the outer surface 234 of the first side wall 23, thus preventing the protrusion 323 from being exposed through the outer surface 234 of the first side wall 23 after installation. The bottom wall 2381 and the multiple side walls 2383 restrict the movement of the protrusion 323 in multiple directions, thereby achieving secure locking and installation.

[0055] In this embodiment, one of the multiple slot sidewalls 2383 of the slot 238 is served by a portion of the mesh body 21. Specifically, a portion of the inner surface 213 of the mesh body 21 serves as one slot sidewall 2383 of the slot 238. In other embodiments, all slot sidewalls 2383 can be served by a portion of the first sidewall 23. For example, by opening the slot 238 in the middle region of the inner surface 232 of the first sidewall 23, all slot sidewalls 2383 of the slot 238 can be served by a portion of the first sidewall 23.

[0056] Furthermore, a groove 214 may be formed on the inner surface 213 of the mesh body 21, and the groove 214 is connected to the slot 238. The groove 214 can be formed by a downward indentation of the inner surface 213 of the mesh body 21. The slot 238 and the groove 214 can be fabricated using a T-shaped grooving tool 80, such as... Figure 2 As shown. The aforementioned groove 214 facilitates the fabrication of the slot 238. The groove 214 also facilitates the installation and locking of the slot 238 and the protrusion 323. During installation, the protrusion 323 can be aligned with the groove 238 first, and then pushed along the groove 238 towards the first sidewall 23 to easily enter the slot 238 and achieve engagement and locking with it. Figure 2 The diagram only schematically illustrates the structure of one slot 238. In actual implementation, there can be two or more slots 238. To achieve a better locking effect, the number of slots 238 can be set according to the length of the first sidewall 23.

[0057] To facilitate installation, an inclined guide surface 23832 can be provided on at least one sidewall 2383 of the slot 238. In this embodiment, guide surfaces 23832 are provided on both the left and right sidewalls 2383. The guide surfaces 23832 facilitate the entry of the protrusion 323 into the slot 238. Furthermore, the inclined guide surfaces 3232 at the edge of the protrusion 323 also facilitate the entry of the protrusion 323 into the slot 238.

[0058] In this embodiment, the first sidewall 23 and the second sidewall 25 are a pair of sidewalls arranged opposite each other, which makes the concealed snap-fit ​​part 238 and the snap-fit ​​member 26 arranged opposite each other. The above arrangement helps to improve their snap-fit ​​effect.

[0059] In this embodiment, the fastener 26 is a bendable spring 26. The spring 26 has a connecting end 262 and a free end 264. The connecting end 262 is connected to the side of the second sidewall 25 away from the net body 21, and the free end 264 is rotatable relative to the connecting end 262.

[0060] Correspondingly, the frame 32 has a mounting surface 322 for supporting the net body 21, a back surface 324 facing away from the mounting surface 322 and away from the net body 21, and a side surface 326 connecting the mounting surface 322 and the back surface 324. After installation, the free end 264 of the fastener 26 presses against the back surface 324, and the back surface 324 serves as the second mating part 325 that cooperates with the fastener 26. A recess may be provided in the area on the back surface 324 that directly contacts and mates with the second mating part 325, such as... Figure 8 As shown, the recessed area can be regarded as the second mating part 325.

[0061] During installation, the clip 26 can be initially positioned vertically, such as... Figure 3 As shown, in this state, the fastener 26 and the second sidewall 25 are substantially in the same plane to facilitate the mounting bracket 30 approaching and abutting against the inner surface 213 of the mesh body 21. After the mounting bracket 30 is placed in the predetermined position (at this time, the protrusion 323 of the mounting bracket 30 and the hidden fastener 238 have completed the engagement and fastening), as... Figure 7 As shown; then, the free end 264 of the buckle 26 can be bent inward, so that the bent free end 264 abuts against the back 324 of the frame 32, thereby realizing the stable installation and locking of the mounting bracket 30 and the speaker grille 20, and the resulting structure is as follows. Figure 8 As shown.

[0062] In specific implementation, the number of the fasteners 26 is two or more. Providing multiple fasteners 26 can further strengthen the stability and reliability of the installation between the mounting bracket 30 and the speaker grille 20. Preferably, the multiple fasteners 26 can be evenly arranged; a larger spacing can be provided between adjacent fasteners 26 to enhance the stability of the fastening while reducing the number of fasteners 26 required.

[0063] Furthermore, the speaker grille 20 may also include:

[0064] The third sidewall 27 is connected to the edge of the third side 21c of the net body 21, and the third sidewall 27 connects the first sidewall 23 and the second sidewall 25.

[0065] The fourth sidewall 29 is connected to the edge of the fourth side 21d of the net body 21. The fourth sidewall 29 connects the first sidewall 23 and the second sidewall 25. The fourth sidewall 29, the first sidewall 23, the third sidewall 27 and the second sidewall 25 are connected end to end, and together with the net body 21, they form an installation space.

[0066] During installation, at least a portion (or all) of the mounting bracket 30 frame 32 can be accommodated within the aforementioned mounting space of the speaker grille 20. Furthermore, the mounting surface 322 of the frame 32 directly or indirectly abuts against the inner surface 213 of the grille body 21, and each side surface 326 of the frame 32 abuts against the inner surfaces of the first side wall 23, the second side wall 25, the third side wall 27, and the fourth side wall 29. Through these accommodating and abutting relationships, the reliability of the installation between the mounting bracket 30 and the speaker grille 20 can be further enhanced.

[0067] In this embodiment, the mesh body 21 is flat, and the plurality of horn holes 212 are evenly distributed on the mesh body 21, penetrating the inner surface 213 and the outer surface 215 of the mesh body 21. In other embodiments, depending on the characteristics of the product or the user's needs, the mesh body 21 may also be a curved panel. On assembled products (e.g., electronic devices such as mobile phones, laptops, tablets, display devices, or televisions), the outer surface 215 of the mesh body 21 is usually exposed and can be observed by the user.

[0068] In this embodiment, the speaker grille 20 is an integrally connected metal structure. The main body 21, the first sidewall 23, the second sidewall 25, the third sidewall 27, and the fourth sidewall 29 are all made from the same metal plate.

[0069] Furthermore, the speaker grille assembly 100 may also include a dustproof mesh 40 and an adhesive 50, both disposed between the speaker grille 20 and the mounting bracket 30. The dustproof mesh 40 can be attached to the inner surface 213 of the grille body 21 using adhesive. The dustproof mesh 40 has small pores (relative to the speaker holes 212), preventing external dust or other solid particles from entering the equipment through the speaker holes 212. In this embodiment, the dustproof mesh 40 is relatively thin, rectangular, and its dimensions in the length and width directions are equivalent to or slightly smaller than the grille body 21. During assembly, the dustproof mesh 40 can be placed in the mounting space of the speaker grille 20 and then attached to the inner surface 213 of the grille body 21 using adhesive. The structure after the dustproof mesh 40 and the speaker grille 20 are assembled is as follows... Figure 3 As shown.

[0070] Colloid 50 can be double-sided tape. For example... Figure 4 As shown, the adhesive 50 can be pre-attached to the mounting surface 322 of the mounting bracket 30 body 32. In this embodiment, a step 3224 can be provided at the edge of the mounting surface 322, and the step 3224 is higher than other areas of the mounting surface 322. The adhesive 50 can be attached to other areas of the mounting surface 322 except for the step 3224. Then, as... Figure 5 and Figure 6As shown, place the mounting bracket 30 close to the speaker grille 20, and after correct alignment, adhere the mounting surface 322 of the bracket 32 ​​to the dustproof mesh 40 and the inner surface 213 of the mesh body 21 using the adhesive 50. At this time, the protrusions 323 on the bracket 32 ​​are also engaged in the slots 238. Then, as... Figure 7 and Figure 8 As shown, bending the free end 264 of the buckle 26 inward so that the bent free end 264 presses against the back 324 of the frame 32 achieves a stable installation and locking of the mounting bracket 30 and the speaker grille 20. The details of the engagement between the slot 238 and the protrusion 323 in the assembled speaker grille assembly 100 can be found in [reference needed]. Figure 9 and Figure 10 As shown. If there is no adhesive 50 or if adhesive 50 fails, after prolonged use, due to gravity and other reasons, the mounting bracket 30 is prone to shifting downwards, causing the protrusion 323 to detach from the slot 238, resulting in the failure of the latch between the speaker grille 20 and the mounting bracket 30. Figure 11 As shown. However, the aforementioned defects do not occur in a very short time and are not easily detected.

[0071] In this embodiment, the mounting bracket 30 can be a decorative strip commonly used in electronic devices. Besides the elongated frame 32 extending primarily along the horizontal plane, the mounting bracket 30 may also include two fixing plates 35. These two fixing plates 35 are disposed on the back 324 of the frame 32 and are positioned opposite each other to fix the mounting bracket 30 to the electronic device. When applied to larger electronic devices such as flat-screen TVs and display panels, the two fixing plates 35 are used to fix the back cover and back panel of the display panel. A receiving space 352 is provided between the two fixing plates 35, which can be used to accommodate a speaker. A through hole (not shown in the figure) may be provided on the frame 32 to facilitate the sound transmission from the speaker.

[0072] It should be noted that in the embodiment shown in the attached figure, the dimensions of the speaker grille 20, mounting bracket 30, etc., in the length direction are extremely large, much larger than the dimensions in the width and thickness directions. For ease of illustration, only a portion of the length of the speaker grille 20, mounting bracket 30, etc., in the length direction is shown in the figure.

[0073] In summary, in this embodiment, by providing snap-fit ​​structures (a concealed snap-fit ​​part 238 on the first sidewall 23 and a snap-fit ​​member 26 on the second sidewall 25) on the two sidewalls (the first sidewall 23 and the second sidewall 25), the speaker grille 20 can be stably and reliably installed at the corresponding position on the product. Furthermore, the inner surface of the sidewall in a relatively conspicuous position (e.g., the first sidewall 23) and the sidewall in a relatively concealed position (e.g., the second sidewall 25) cannot be observed by the user during use. By placing the two snap-fit ​​structures for stable installation in these unobservable positions, the aesthetics of the product can be avoided. Therefore, the speaker grille 20 can achieve a stable installation without compromising the product's appearance.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
