Description

Technical Field

[0001] The present invention relates to the field of sound boxes, and in particular to a detachable mesh structure with a high through-porosity and a sound box. Background Art

[0002] A speaker is a device that can convert audio signals into sound. Its main function is to convert audio electrical energy into corresponding sound energy and radiate it into space for people to hear directly.

[0003] With the advancement of technology and people's need for music, in order to allow people to enjoy music anytime and anywhere during outdoor activities, travel, picnics or other occasions, portable small speakers were born. The biggest feature of portable small speakers is that they are small and light. In addition, since they may be carried and placed in different environments, they also need to have good shock resistance and durability.

[0004] Most of the existing portable small speakers are equipped with speaker grilles. As an important component of portable small speakers, the speaker grilles are not only lightweight and meet the portable small speakers' pursuit of lightweight, but also can play a protective role, such as preventing debris from entering the speaker body, preventing pets from damaging speaker components, and blocking some direct sunlight to avoid accelerated aging of speaker components. Therefore, speaker grilles are widely used in portable small speakers. However, although existing portable small speakers are equipped with speaker grilles, the speaker grilles are mostly fixed to the speaker body directly or indirectly with bolts. For portable small speakers, this connection method is not reliable. The main reason is that the speaker itself will vibrate when making a sound, and the speaker will also experience shaking when carried around daily, which can easily cause the bolts to loosen. Secondly, in some environments with high humidity, the bolts are at risk of rusting. Finally, once you choose to use bolts, you will compromise on the appearance, and even need to thicken the speaker grille to meet the needs of installing the bolts. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a detachable grille structure with a high through-porosity and a speaker to solve the problem that the speaker grille on the existing portable small speaker is fixed with bolts, and the bolts become loose due to the vibration of the speaker grille during use, causing the speaker grille to fall off, and even the speaker grille needs to be thickened and sacrificed in weight to meet the need for bolt installation. The specific technical solution is as follows:

[0006] In a first aspect of the embodiments of the present application, a detachable mesh structure with a high through-porosity is provided, wherein the mesh structure comprises an elastic cover and a substrate assembly which are stacked and interconnected, wherein the outer periphery of the elastic cover protrudes toward the substrate assembly to form a protrusion, which surrounds the substrate assembly, and the protrusion protrudes more than the substrate assembly, and the substrate assembly is provided with a slot for detachably connecting a speaker.

[0007] In some embodiments, the substrate assembly is provided with an avoidance groove, and the locking groove is arranged on the inner wall of the avoidance groove.

[0008] In some embodiments, a distance between a bottom surface of the protrusion and a bottom surface of the substrate assembly is greater than 0.3 mm and less than 0.6 mm.

[0009] In some embodiments, the elastic cover is provided with a first opening, the substrate assembly is provided with a second opening, the first opening is connected to the second opening, and the aperture of the first opening is smaller than the aperture of the second opening.

[0010] In some embodiments, the first opening and the second opening are both circular, and the difference between the radius length of the first opening and the radius length of the second opening is no more than 0.1 mm.

[0011] In some embodiments, reinforcing ribs are provided on the inner wall of the avoidance groove, and the reinforcing ribs are disposed on both sides of the slot.

[0012] In some embodiments, the elastic cover is made of TPU, and the substrate assembly is made of PC.

[0013] In some embodiments, the elastic cover is provided with a positioning column, and the substrate assembly is provided with a positioning hole to install the positioning column.

[0014] A speaker is applied to the above-mentioned detachable mesh structure with high through-porosity, comprising a speaker body and a mesh structure, wherein the speaker body is provided with a latching protrusion on its sound-emitting side, and the speaker body is detachably connected to the latching slot on the mesh structure via the latching protrusion.

[0015] In some embodiments, the speaker body is provided with a groove, the groove is used to accommodate the reinforcing rib, and the side surface of the reinforcing rib abuts against the inner wall of the groove.

[0016] Beneficial effects of the embodiments of the present application:

[0017] 1. The grille structure of this application is detachable and matched with the speaker, which is convenient for users to install and replace;

[0018] 2. The elastic cover is made of TPU material. In daily use, people feel more comfortable when touching the elastic cover. In addition to preventing debris from entering the speaker body, preventing pets from damaging speaker components, and blocking some direct sunlight to avoid accelerated aging of speaker components, the elastic cover can also play a shock-absorbing role when falling, improving overall durability;

[0019] 3. Use the protruding part of the elastic cover to contact the speaker, reduce the contact surface between the substrate assembly and the speaker, and effectively reduce abnormal noise caused by vibration;

[0020] 4. Limiting the height of the protruding portion can reduce the gap between the substrate assembly and the sound output surface of the speaker, thereby reducing the impact on the sound emitted by the speaker;

[0021] 5. The avoidance groove can be used to not only accommodate the protrusions on the sound outlet surface of the speaker, but also to accommodate related components on the speaker, such as speakers, etc., effectively utilizing the space to further reduce the size of the speaker and achieve a compact design;

[0022] 6. The design of the first opening being smaller than the second opening makes it difficult for people to observe the substrate assembly when looking directly at the mesh structure, effectively preventing the visual misalignment of the holes, making the overall appearance more beautiful. In addition, the substrate assembly will be covered by the elastic cover except for the bottom surface. When mesh assemblies of different colors need to be produced, only the color of the elastic cover needs to be adjusted, thereby reducing production costs.

[0023] 7. The strength of the substrate assembly can be enhanced by adding reinforcing ribs to ensure that when the card protrusion is engaged with the card slot or the card protrusion is removed from the card slot, the substrate assembly has sufficient strength to support it so that it is not easily damaged and is more durable.

[0024] Additional aspects and advantages of the present invention will be given in part in the description below, and in part will become apparent from the description below, or will be understood through the practice of the present invention. Of course, it is not necessary to achieve all of the advantages described above at the same time to implement any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] This application describes a detachable mesh structure with high through-porosity and a speaker box detachably matched with the mesh structure, and Figure 1 It can be seen that the technical solution of the present application is applied in the field or the speakers targeted are small speakers, portable small speakers or outdoor speakers;

[0038] See also Figure 1 , Figure 2 and Figure 5 The present application provides a detachable mesh structure with a high through-porosity. The mesh structure 2 includes an elastic cover 21 and a substrate assembly 22 which are stacked and connected to each other. The outer periphery of the elastic cover 21 protrudes toward the substrate assembly 22 to form a protruding portion 212. The protruding portion 212 surrounds the substrate assembly 22. The protruding portion 212 is protruding compared to the substrate assembly 22. The substrate assembly 22 is provided with a slot 222 for detachably connecting the speaker 1. Specifically, the elastic cover 21 has a receiving cavity 211 to accommodate the substrate assembly 22. The substrate assembly 22 is responsible for connecting the speaker 1. Since the mesh structure 2 is detachably connected to the speaker 1, it is necessary to ensure that the elastic cover 21 and the substrate assembly 22 are firmly connected. The specific molding process between the elastic cover 21 and the substrate assembly 22 can refer to two-color injection molding, secondary injection molding, etc. Preferably, the elastic cover 21 is provided with a positioning column 214, and the substrate assembly 22 is provided with a positioning hole 225 to install the positioning column 214. By setting the positioning column 214 and the positioning hole 225, the positions of the elastic cover 21 and the substrate assembly 22 are further fixed relatively.

[0039] In some embodiments, the elastic cover 21 is made of TPU material, and the substrate assembly 22 is made of PC material. Since the elastic cover 21 is exposed to the outside relative to the substrate assembly 22, and the TPU material is softer than the PC material, the elastic cover 21 can provide a more comfortable touch during daily use. At the same time, in addition to preventing debris from entering the interior of the speaker 1, preventing pets from damaging the components of the speaker 1, and blocking part of the direct sunlight to avoid accelerated aging of the components of the speaker 1, the elastic cover 21 can also play a shock-absorbing role when falling, thereby improving the overall durability. As a component connected to the speaker 1, the substrate assembly 22 must have a higher rigidity than the elastic cover 21, but it must also have deformation ability. Therefore, it is a better choice for the substrate assembly 22 to be made of PC material;

[0040] See also Figure 2-4Furthermore, the elastic cover 21 is integrally formed with the above-mentioned protruding portion 212 on one side of the accommodating cavity 211. The protruding portion 212 exceeds or is higher than the substrate assembly 22. The substrate assembly 22 is provided with a card slot 222 to cooperate with the card protrusion 11 of the speaker 1 for detachable cooperation. When the mesh structure 2 or the substrate assembly 22 is installed on the sound-emitting surface of the speaker 1, the protruding portion 212 of the elastic cover 21 will abut against the sound-emitting surface of the speaker 1, and there is a gap between the substrate assembly 22 and the sound-emitting surface of the speaker 1. The purpose of forming the above-mentioned protruding portion 212 is to weaken the vibration generated by the speaker 1 itself when it emits sound and the surface mesh As for the influence of structure 2, it can be understood that the sound box 1 will vibrate when making a sound, which is caused by components such as the speaker 12 inside the sound box 1, and the elastic cover 21 has a certain elasticity and flexibility, which makes it have a certain shock absorption and buffering ability. Therefore, using the protruding portion 212 of the elastic cover 21 to contact the sound box 1 can effectively reduce abnormal noise caused by vibration. When a force is applied to the substrate assembly 22 to install or snap it onto the sound box 1, the sound box 1 will form a reaction force in the direction of the elastic cover 21 to squeeze the elastic cover 21, so that the mesh structure 2 is firmly installed on the sound box 1.

[0041] It is worth mentioning that in this embodiment, the distance between the bottom surface of the protruding portion 212 and the bottom surface of the substrate assembly 22 is less than 0.6 mm. It can be understood that when the mesh structure 2 is installed on the sound output surface of the speaker 1, the elastic cover 21, the substrate assembly 22 and the sound output surface of the speaker 1 will form a groove-like structure. It is well known that in the process of sound propagation, if the sound encounters a groove-like structure, it will affect the distribution of the sound, which may cause the sound to be more focused or dispersed in certain directions, or affect the frequency of the sound, and may cause reflection or diffraction, etc. Therefore, in this embodiment, the distance between the bottom surface of the protruding portion 212 and the bottom surface of the substrate assembly 22 is limited to less than 0.6 mm, which can reduce the gap between the substrate assembly 22 and the sound output surface of the speaker 1, thereby reducing the impact on the sound emitted by the speaker 1;

[0042] See also Figure 2 and Figure 4Preferably, in this embodiment, the distance between the bottom surface of the protrusion 212 and the bottom surface of the substrate assembly 22 is limited to greater than 0.3 mm. This design is a redundant design based on an achievable injection molding process. During the injection molding process, affected by mold precision, material properties, environmental factors, etc., the elastic cover 21 and the substrate assembly 22 may have dimensional deviations after molding. Therefore, in order to ensure that the sound of the speaker 1 is not affected as much as possible, a certain gap should be left between the substrate assembly 22 and the sound-emitting surface of the speaker 1. The smaller the height of the protrusion 212, the smaller the impact on the sound emitted by the speaker 1, and the more difficult the manufacturing process is. The manufacturer can make adjustments based on the achievable process. This is the optimal range obtained by comprehensively considering the difficulty of the manufacturing process, the sound effect of the speaker 1, and the shock absorption effect.

[0043] See also Figure 4 In some embodiments, the substrate assembly 22 is provided with an avoidance groove 221, and the card slot 222 is arranged on the inner wall of the avoidance groove 221. It can be understood that in order to meet the characteristics of small size and light weight of the portable small speaker, the space inside the speaker 1 should be utilized as much as possible. Specifically, the surface mesh structure 2 in this embodiment is essentially also an external shell part of the speaker 1. By setting the avoidance groove 221, it can not only be used to accommodate the card protrusion 11 on the sound output surface of the speaker 1, but also can accommodate related components on the speaker 1, such as the speaker 12, etc. Effective use of space can further reduce the size of the speaker 1, realize a compact design, and be easy to carry. Since the surface mesh assembly and the speaker 1 are detachably matched through the card slot 222 and the card protrusion 11, it is also convenient for users to disassemble and replace them.

[0044] See also Figure 3 In this embodiment, when the sound box 1 is equipped with a speaker 12, the elastic cover 21 and the substrate assembly 22 are both raised upward with the center of one side surface and form a corresponding accommodating cavity 211 and avoidance groove 221 on the other side surface. Specifically, the bottom surfaces of the accommodating cavity 211 and the avoidance groove 221 are curved surfaces, so that the shapes of the elastic cover 21 and the substrate assembly 22 are similar to the sound waves propagated in the form of spherical waves generated by the speaker 12 arranged in the avoidance groove 221, so that the sound box 1 can form a relatively uniform sound field to improve the auditory experience; it is worth mentioning that under this shape, the substrate assembly 22 will be covered by the elastic cover 21 in addition to the bottom surface. When the color of the mesh assembly needs to be replaced, only the color of the elastic cover 21 needs to be adjusted. During the production process, it is possible to avoid adjusting the colors of the elastic cover 21 and the substrate assembly 22 at the same time due to the need for unified color, thereby reducing the steps required to produce mesh assemblies of different colors and reducing the production cost of producing mesh assemblies of different colors.

[0045] See also Figure 2In some embodiments, the elastic cover 21 and the substrate assembly 22 respectively have a first opening 213 and a second opening 223 that are connected to each other. The number of the first opening 213 and the second opening 223 is not limited and can be adjusted according to the area of ​​the elastic cover 21 and the substrate assembly 22, wherein the aperture of the first opening 213 is smaller than the aperture of the second opening 223. Preferably, the first opening 213 and the second opening 223 are both circular, and the radius length of the first opening 213 differs from the radius length of the second opening 223 by no more than 0.1 mm. In this embodiment, the design that the first opening 213 is smaller than the second opening 223 can make it difficult for people to observe the substrate assembly 22 when looking directly at the mesh structure 2, effectively preventing the visual misalignment of the holes and making the overall appearance more beautiful. Based on the principle of sound wave reflection, the difference between the radius length of the first opening 213 and the radius length of the second opening 223 should be minimized as much as possible, thereby reducing the impact on the sound emitted by the speaker 1 and ensuring the continuity and consistency of sound propagation.

[0046] See also Figure 5 In some embodiments, reinforcing ribs 224 are provided on the inner wall of the avoidance groove 221, and reinforcing ribs 224 are arranged on both sides of each slot 222. It can be understood that in order to pursue the lightweight of the surface mesh structure 2, the thickness of the elastic cover 21 and the substrate assembly 22 is relatively thin. Because the slot 222 needs to be opened on the avoidance groove 221, when assembling the surface mesh structure 2 on the speaker 1 or removing the lower mesh structure 2 from the speaker 1, especially when the protrusion 11 of the speaker 1 and the slot 222 of the substrate assembly 22 are engaged or separated, the main force position is near the slot 222, so that the thinner substrate assembly 22 is easily damaged when subjected to force. By adding reinforcing ribs 224, the strength of the substrate assembly 22 can be strengthened to ensure that when the protrusion 11 is engaged with the slot 222 or the protrusion 11 is detached from the slot 222, the substrate assembly 22 has sufficient strength support to prevent it from being damaged and make it more durable.

[0047] The present application also provides a speaker to match the above-mentioned mesh structure 2. Specifically, the speaker 1 is provided with a groove 13 on its sound-emitting side. When the slot 222 of the mesh structure 2 is subjected to force and is engaged with the protrusion 11 on the speaker body 1, the reinforcing rib 224 enters the groove 13 synchronously. It should be noted that in this embodiment, the reinforcing rib 224 is columnar. When the slot 222 is engaged with the protrusion 11, the reinforcing rib 224 and the groove 13 are slightly misaligned, that is, a certain force needs to be applied to the reinforcing rib 224 to squeeze it into the groove 13. This is also due to the fact that the reinforcing rib 224 and the substrate assembly 22 are integrally formed and the PC material supports its deformation. After the reinforcing rib 224 enters the groove 13, part of the side surface of the reinforcing rib 224 abuts against the inner wall of the groove 13.

[0048] See also Figure 3 and Figure 5 In some preferred embodiments, the speaker 1 is provided with grooves 13 on both sides of each protrusion 11. When the mesh structure 2 is installed on the speaker 1, the reinforcing rib 224 on the left side of the groove 222 will enter the groove 13 on the left side of the protrusion 11, and the reinforcing rib 224 on the left side of the groove 222 will abut against the right inner wall of the groove 13 on the left side of the protrusion 11. The reinforcing rib 224 on the right side of the groove 222 will enter the groove 13 on the right side of the protrusion 11, and the reinforcing rib 224 on the right side of the groove 222 will abut against the right inner wall of the groove 13 on the left side of the protrusion 11. The left inner wall of the groove 13 on the right side is abutted, so the two reinforcing ribs 224 located on both sides of the slot 222 can play a limiting role and form a force to clamp the speaker 1 after squeezing into the corresponding grooves 13. The reinforcing ribs 224 can not only strengthen the strength of the substrate assembly 22, but also serve as a guiding structure to guide the mesh assembly and the speaker 1 for assembly, and then use two relatively arranged reinforcing ribs 224 to clamp part of the speaker 1, so that the mesh structure 2 is firmly placed on the speaker 1, further enhancing the overall stability and durability.

[0049] The following are various shapes of reinforcing ribs 224 provided in this application:

[0050] See also Figure 5 and Figure 6 In some embodiments, the reinforcing rib 224 is semi-cylindrical, and one end of the reinforcing rib 224 faces the avoidance groove 221 or the center of the substrate assembly 22, and the other end of the reinforcing rib 224 faces the edge of the substrate assembly 22. In this embodiment, the inner wall of the groove 13 matched with the reinforcing rib 224 is a curved surface;

[0051] See also Figure 5 and Figure 7 In some embodiments, the reinforcing rib 224 is in the shape of a rectangular parallelepiped, and one end of the reinforcing rib 224 is toward the avoidance groove 221 or the center of the substrate assembly 22, and the other end of the reinforcing rib 224 is set toward the edge of the substrate assembly 22. The reinforcing rib 224 is used to cooperate with the end face corner of the groove 13 to form a curved surface so as to guide the reinforcing rib 224 into the groove 13; in this embodiment, the groove 13 is a rectangular groove.

[0052] See also Figure 5 and Figure 8 In some embodiments, the reinforcing rib 224 is in the shape of a rectangular parallelepiped, and one end of the reinforcing rib 224 is toward the avoidance groove 221 or the center of the substrate assembly 22, and the other end of the reinforcing rib 224 is set toward the edge of the substrate assembly 22. The reinforcing rib 224 is used to cooperate with the end face corner of the groove 13 to form an inclined surface so as to guide the reinforcing rib 224 into the groove 13; in this embodiment, the groove 13 is a rectangular groove.

[0053] By comparing the above three embodiments, compared with the semi-cylindrical reinforcing rib 224 and under the premise of having a certain guiding ability, the rectangular reinforcing rib 224 can better exert the force on the groove 13.

[0054] In the present application, the reinforcing rib 224 can only be provided on the substrate assembly 22, and the groove 13 can only be provided on the speaker 1. It is understandable that if the groove 13 is formed on the substrate assembly 22, the substrate assembly 22 will be further fragile, and even a simple snap fit may damage the substrate assembly 22. The speaker 1 itself is strong enough, and the corresponding groove 13 is provided on the speaker 1 and will not have much impact on it, and there is no reason to provide the reinforcing rib 224 on the speaker 1.

[0055] In the present application, the number of the card protrusions 11 and the card slots 222 is not limited:

[0056] In some embodiments, four latching protrusions 11 are provided on the speaker 1, and four latching grooves 222 are provided on the substrate assembly 22 on the corresponding mesh structure 2. Specifically, with the speaker 12 on the speaker 1 as the midpoint, the four latching protrusions 11 are evenly distributed in a ring shape around the speaker 12 of the speaker 1, and the four latching grooves 222 are evenly distributed in a ring shape on the inner wall of the avoidance groove 221. In this embodiment, reinforcing ribs 224 are provided on both sides of each latching groove 222, and grooves 13 for matching the reinforcing ribs 224 are provided on both sides of each latching protrusion 11. Through the cooperation of the four groups of latching protrusions 11 and the latching grooves 222, the smaller speaker 1 and the mesh structure 2 can be firmly connected.

[0057] See also Figure 2 In some embodiments, the speaker 1 is in a cube shape, and the speaker 1 forms an annular protrusion 14 around the speaker 12, with the inner ring close to the speaker 12 and the outer ring away from the speaker 12. The annular protrusion 14 is arranged in the inner ring and has four equidistantly distributed first protrusions 111 on the annular protrusion 14. The speaker 1 is provided with four annularly equidistantly distributed second protrusions 112 on the outer ring. The first protrusions 111 and the second protrusions 112 are alternately arranged and the second protrusions 112 are arranged close to the four corners of the speaker 1. The annular protrusion 14 has a notch and serves as the above-mentioned groove 13. The inner wall of the avoidance groove 221 is provided with 8 grooves 222 for matching the first protrusion 111 and the second protrusion 112. Reinforcing ribs 224 are arranged on both sides of each groove 222. Through the cooperation of 8 groups of protrusions 11 and grooves 222, the larger speaker 1 and the mesh structure 2 can be firmly connected.

[0058] See also Figure 4In order to facilitate the matching between the card protrusion 11 and the card slot 222, the present application also provides an embodiment, please refer to the figure, the card protrusion 11 includes a card protrusion main body 1111, and a triangular protrusion 1112 is integrally formed on the outer side of the end of the card protrusion main body 1111, and the shape of the card slot 222 matches the triangular protrusion 1112, and the outer side of the card slot 222 forms an inclined surface inclined inwardly to facilitate guiding the card protrusion main body 1111 to enter, that is, during the matching process of the card protrusion 11 and the card slot 222, the triangular protrusion 1112 on the card protrusion main body 1111 first contacts the inclined surface on the outer side of the card slot 222 and enters the card slot 222 under the guidance of the inclined surface. At this time, the outer side of the card protrusion main body 1111 or the card slot 222 is squeezed and deformed until the triangular protrusion 1112 of the card protrusion main body 1111 enters the card slot 222 and then recovers.

[0059] Compared to the speakers 1 placed in relatively fixed locations such as houses and studios, the speakers 1 targeted by the present application are mostly used outdoors and often need to be moved and carried. Therefore, there are clear requirements for their weight, size, durability, stability, protection capabilities, etc. The embodiments provided in this application are all based on this design.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
