Description

Technical Field

[0001] This utility model relates to a small speaker cover, specifically a small speaker cover structure. Background Technology

[0002] A mini speaker is a portable audio device typically used to play music, voice, or other audio content. Due to its small size and portability, mini speakers are widely used in homes, outdoor activities, and travel. The speaker grille is an important component of the speaker, primarily used to protect the speaker unit, while also affecting the speaker's appearance and sound quality.

[0003] Most existing speaker grilles are made of plastic through injection molding. Plastic material lacks rigidity, and when the speaker grille collides with the outside world, it is easy to break, making it difficult to protect the speaker unit inside the speaker. Utility Model Content

[0004] The purpose of this utility model is to provide a small speaker cover structure, which has the advantages of solving the problem that existing small speaker covers are mostly made of plastic through injection molding. The plastic material is not rigid enough, and when the small speaker cover is in contact with the outside world, it is easy to break and it is difficult to protect the speaker unit inside the small speaker.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small speaker mask structure, which includes a speaker mask assembly. The speaker mask assembly includes a mask shell, which is a hollow cavity structure with an opening on one side. A reinforcing component is provided inside the cavity. The reinforcing component includes a fixing block. Four fixing blocks are provided, and the four fixing blocks are equidistantly arranged inside the mask shell. A first reinforcing ring is provided inside each fixing block. The outer wall of the first reinforcing ring is in contact with the inner wall of the mask shell, and a second reinforcing ring is provided on the first reinforcing ring.

[0006] Preferably, the fixing block includes a connecting block, the connecting block has an arc-shaped structure, and the end of the connecting block away from the mask shell has a guide block, there is an angle between the guide block and the connecting block, the angle value of which is between ° and °, and the end of the guide block away from the connecting block is provided with a recessed platform.

[0007] Preferably, the outer sides of the first reinforcing ring and the outer sides of the second reinforcing ring are flush, and the thickness of the first reinforcing ring is greater than the thickness of the second reinforcing ring. The first reinforcing ring is located on the sinking platform, and the second reinforcing ring is located below the sinking platform.

[0008] Preferably, the top of the mask shell is provided with a sound-permeable hole that penetrates the mask shell, and the mask shell is also provided with a groove.

[0009] Preferably, the device also includes an installation component, which includes a fixed shaft disposed below the interior of the groove. A locking block is provided on the outer surface of the fixed shaft, and the locking block can rotate around the fixed shaft as the center.

[0010] Preferably, one side of the locking block is flat and the other side of the locking block is arc-shaped. A telescopic spring is provided at the end of the locking block away from the fixed shaft, and the end of the telescopic spring away from the locking block is provided on the inner wall of the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a small speaker mask structure. The small speaker mask structure is reasonably designed and simple. By setting reinforcement components, the first reinforcement ring and the second reinforcement ring are snapped into the inside of the mask shell, which can strengthen the strength of the mask shell and prevent the mask shell from being damaged by collision. It can also provide better protection for the speaker unit inside the mask shell.

[0013] 2. By setting a fixing block inside the mask shell, the fixing block is pushed outward by the ejector pin during the injection molding of the mask shell. This facilitates demolding of the mask shell without leaving ejection marks inside the mask shell. At the same time, the first and second reinforcing rings block the outside of the fixing block, making the inside of the mask shell more aesthetically pleasing.

[0014] 3. By setting a fixing component, the mask shell is pushed into the speaker cabinet. When the locking block moves to the slot position inside the speaker cabinet, the locking block rotates outward under the elastic force of the telescopic spring until it engages with the slot, thus making it easy to fix the mask shell inside the speaker cabinet. At the same time, by pushing the mask shell inward, the locking block can be rotated inward, so that the locking block separates from the slot, making it easy to remove the mask shell.

[0026] Please see Figure 1 , Figure 3 This utility model provides an embodiment of a small speaker mask structure, which includes a speaker mask assembly 1. The speaker mask assembly 1 includes a mask shell 11, which is a hollow cavity structure with an opening on one side. A reinforcing assembly 2 is provided in the cavity. The reinforcing assembly 2 includes four fixing blocks 21, which are equidistantly arranged inside the mask shell 11. A first reinforcing ring 22 is provided inside the fixing block 21. The outer wall of the first reinforcing ring 22 is in contact with the inner wall of the mask shell 11, and a second reinforcing ring 23 is provided on the first reinforcing ring 22. The first reinforcing ring 22 and the second reinforcing ring 23 are located inside the mask shell 11. When the mask shell 11 collides with the outside, the first reinforcing ring 22 and the second reinforcing ring 23 support the inner wall of the mask shell 11, thereby improving the strength of the mask shell 11.

[0027] Please see Figure 4 The fixing block 21 includes a connecting block 211, which has an arc-shaped structure. The end of the connecting block 211 away from the mask shell 11 has a guide block 212. There is an angle between the guide block 212 and the connecting block 211, and the angle value is between 75° and 90°. The end of the guide block 212 away from the connecting block 211 is provided with a recessed platform 213. The first reinforcing ring 22 can be moved to the upper end of the recessed platform 213, and the first reinforcing ring 22 is located between the mask shell 11 and the guide block 212.

[0028] Please see Figure 3 The outer side of the first reinforcing ring 22 is flush with the outer side of the second reinforcing ring 23, and the thickness of the first reinforcing ring 22 is greater than the thickness of the second reinforcing ring 23. The first reinforcing ring 22 is located on the recessed platform 213, and the second reinforcing ring 23 is located below the recessed platform 213. The recessed platform 213 limits the first reinforcing ring 22, so that the first reinforcing ring 22 and the second reinforcing ring 23 are fixed to the inner wall of the mask shell 11. At the same time, the first reinforcing ring 22 and the second reinforcing ring 23 are made of rigid material.

[0029] Please see Figure 2 The mask housing 11 has a sound-permeable hole 12 at the top, which penetrates the mask housing 11. The mask housing 11 also has a groove 13.

[0030] Please see Figure 6The mounting component 3 includes a fixed shaft 31, which is located inside the lower part of the groove 13. A locking block 32 is provided on the outer surface of the fixed shaft 31. The locking block 32 can rotate around the fixed shaft 31. One side of the locking block 32 is flat, and the other side is arc-shaped. A telescopic spring 33 is provided at the end of the locking block 32 away from the fixed shaft 31. The end of the telescopic spring 33 away from the locking block 32 is located on the inner wall of the groove 13. When the telescopic spring 33 is compressed by the locking block 32, the locking block 32 rotates until its outer end is flush with the outer side of the mask shell 11. When the telescopic spring 33 is not under force, the upper end of the locking block 32 rotates to the outside of the groove 13, and the upper end of the locking block 32 is in a horizontal state. At the same time, the outer side of the upper end of the locking block 32 extends outward beyond the outer side of the mask shell 11.

[0031] Please refer to it again. Figures 1 to 6 In use, when the mask shell 11 needs to be injection molded, to facilitate demolding, ejector pins are positioned outside the fixing block 21. The ejector pins push the mask shell 11 outwards from the fixing block 21, thus ejecting it without damaging it. Simultaneously, by moving the first reinforcing ring 22 inside the fixing block 21 and placing it on the countersunk platform 213, the fixing block 21 secures the first reinforcing ring 22. This ensures that the outer sides of the first and second reinforcing rings 22 and 23 are in contact with the inner wall of the mask shell 11, reinforcing the mask shell 11. When the mask shell 11 needs to be installed on a speaker, [further details are needed]. Push the mask shell 11 directly into the outside of the speaker. The speaker blocks the locking block 32, causing the locking block 32 to rotate along the fixed shaft 31 into the groove 13. When the locking block 32 moves to the slot position on the mask shell 11, the locking block 32 moves outward under the elastic force of the telescopic spring 33 and engages with the slot, thus fixing the mask shell 11. When it is necessary to remove the mask shell 11, continue to push the mask shell 11 inward, causing the mask shell 11 to drive the locking block 32 inward. After the locking block 32 moves into the groove 13, rotate the mask shell 11 so that the locking block 32 intersects with the slot, and the inner wall of the speaker is always located outside the locking block 32, so that the locking block 32 cannot rotate outward, thus making it easy to remove the mask shell 11.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
