[0001] The utility model relates to the technical field of acoustic accessories, and particularly relates to a mesh cloth assembly, a housing structure and an electronic product. Background Art

[0002] In modern speaker design, the combined use of a plastic bracket and a mesh cloth has become a common structural configuration. As the main support structure of the speaker, the outer surface of the plastic bracket is usually covered with a mesh cloth layer. The main purpose of this design is to improve the aesthetics of the speaker. At the same time, the mesh cloth layer can also protect the internal speaker unit to a certain extent, prevent the intrusion of dust and other small particulate matters, and thus extend the service life of the speaker. In addition, the mesh cloth layer can also provide certain acoustic performance for the speaker. Through its special pore structure, it helps the diffusion and propagation of sound, making the sound emitted by the speaker more natural and clear.

[0003] However, the installation method of the mesh cloth has certain limitations in practical applications. At present, the installation of the mesh cloth layer mainly adopts a segmented setting method, that is, one piece of mesh cloth is installed on one side of the plastic bracket. Although this setting method is relatively simple in operation, it will inevitably form obvious joints and large gaps between every two adjacent pieces of mesh cloth. These gaps not only affect the overall aesthetics of the speaker appearance, but also may affect the purity of the sound quality and reduce the overall performance of the speaker during the sound propagation process.

[0023] The mesh cloth assembly proposed by the present utility model, please refer to Figure 1 and Figure 2 , which includes:

[0024] A support frame 10; and

[0025] A sleeve mesh cloth 20. The sleeve mesh cloth 20 has a plurality of connecting surfaces, and the plurality of connecting surfaces enclose to form an installation cavity 20b having an insertion port 20a. The support frame 10 can pass through the insertion port 20a, and at least part of the structure of the support frame 10 passes through the insertion port 20a and is located in the installation cavity 20b; wherein, the support frame 10 and the sleeve mesh cloth 20 are of an integral structure.

[0026] In the technical solution of the present utility model, the sleeve mesh cloth 20 is processed by a preforming process into a barrel-shaped structure with a shaping effect. When assembling the mesh cloth assembly, the sleeve mesh cloth 20 is sleeved on the outer surface of the support frame 10, so that the plurality of connecting surfaces can be simultaneously attached to the respective side surfaces of the support frame 10. In this way, it is prevented that the sleeve mesh cloth 20 forms joints and gaps on the outer surface of the support frame 10, thereby avoiding affecting the purity of the sound quality and reducing the overall performance of the speaker, and being able to improve the appearance expressiveness of the electronic product using this mesh cloth assembly.

[0027] It can be understood that the mesh component is applied to electronic products, such as speakers and voice interaction devices. In this way, the appearance expressiveness of the electronic products can be ensured. Specifically, the sleeve mesh 20 in the mesh component can be structurally shaped through a preforming process by pressure holding and heating, so as to facilitate the assembly process of the sleeve mesh 20 and the support frame 10.

[0028] In an embodiment, the mesh component is applied to a small speaker. The interior of the support frame 10 is a cavity structure, which can accommodate the speaker and other electronic components of the speaker and provide a limiting structure, such as a clamping block, a screw hole, etc., for fixing the speaker and the electronic components, which will not be limited here.

[0029] In this embodiment, the connecting surface of the sleeve mesh 20 includes an integrated end face and four side faces. The four side faces are all connected to the end face and are of an integrated structure. An end face and four side faces enclose an installation cavity 20b with an insertion port 20a. The support frame 10 can pass through the insertion port 20a and extend into the installation cavity 20b, and closely adhere to the inner wall of the installation cavity 20b. At this time, each face of the sleeve mesh 20 can correspondingly fit each outer side face of the support frame 10. In such a posture, there will be no seams and gaps caused by splicing on the outer surface of the mesh component, thus avoiding affecting the purity of the sound quality and reducing the overall performance of the speaker.

[0030] Furthermore, the mesh component further includes an adhesive layer, which adhesively bonds the outer surface of the support frame 10 and the inner surface of the sleeve mesh 20, so that the support frame 10 and the sleeve mesh 20 are of an integrated structure. Specifically, a glue spraying structure can be used to spray glue on the outer surface of the support frame 10, so as to form an adhesive layer on the outer surface of the support frame 10, thereby realizing the adhesion between the support frame 10 and the sleeve mesh 20. By using the adhesive means, a large gap between the support frame 10 and the sleeve mesh 20 can be avoided, and the appearance of the "bulge" structure can be overcome. This has a certain positive impact on speakers with high sound quality requirements. And by adhesively bonding the outer surface of the support frame 10 and the inner surface of the sleeve mesh 20 with the adhesive layer, the connection reliability between the two can be improved.

[0031] In an embodiment of the present utility model, please refer to Figure 3, the support frame 10 includes an end face and a plurality of side faces all connected to the end face. The end face and at least one side face are provided with bonding avoidance areas. The bonding avoidance areas are arranged to avoid the bonding layer, that is, the bonding avoidance areas are the outer surface areas of the support frame 10 where there is no bonding layer. Specifically, the mesh component is applied to a single-vibration system speaker. There is only one magnetic circuit system and one vibration system in the speaker of this kind, and the diaphragm in the vibration system vibrates at one position; the support frame 10 includes an end face and four side faces all connected to the end face. One of the side faces corresponds to the diaphragm, and a bonding avoidance area is provided on this side face. The bonding avoidance area is arranged at the outer edge of this side face, and at least part of the area of the end face is also provided with a bonding avoidance area. The reason for setting the bonding avoidance area on the end face is that the pulling surface area of the end face is relatively large, and at the same time, due to the thinness factor of the sleeve mesh 20, it is relatively transparent. If a bonding layer is used on the end face, the mesh will be closely attached to the end face of the support frame 10, and there will be a phenomenon of glue reflection, which will affect the user experience of the product; the reason for setting the bonding avoidance area on the side face is to leave a certain gap between the sleeve mesh 20 and the support frame 10, so as to facilitate the diaphragm to vibrate freely in the air and meet the acoustic requirements; in another embodiment, the mesh component is applied to a dual-vibration system speaker, that is, it has at least one magnetic circuit system and two vibration systems. The two vibration systems are respectively arranged at both ends of the magnetic circuit system to achieve bilateral sound emission. At this time, bonding avoidance areas are arranged along the outer edges of any two opposite side faces in the support frame 10, and at least part of the area of the end face is also provided with a bonding avoidance area, so as to meet the requirements of users in terms of product experience and acoustic performance.

[0032] In an embodiment of the present invention, please refer to Figure 4 , the support frame 10 includes an iron mesh 101 and a plastic housing 102. An iron mesh 101 is provided on one side face of the plastic housing 102. The iron mesh 101 forms a sound outlet hole 10a facing the diaphragm of the speaker. By using the characteristic of high strength of iron, the sound outlet opening rate of the iron mesh 101 can be increased as much as possible to improve the electro-acoustic sound output effect and sound quality; both the side face of the plastic housing 102 where the iron mesh 101 is provided and one end face of the plastic housing 102 form bonding avoidance areas. It can be understood that because the iron mesh 101 and the plastic housing 102 are assembled together through corresponding assembly processes, there will be a step difference between the iron mesh 101 and the plastic due to dimensional tolerances after assembly. At this time, a bonding avoidance area is arranged at the outer edge of the side face of the plastic housing 102 where the iron mesh 101 is provided, which can prevent the mesh from sticking tightly to the plastic housing 102, thereby avoiding the step difference at the connection between the mesh and the plastic bracket and the iron mesh 101, and thus avoiding the imprint caused by the step difference, thereby improving the appearance expressiveness of the electronic product.

[0033] In an embodiment of the present invention, the characteristics of the mesh component are a combination formed by one or more of A1, B1, and C1, where:

[0034] A1: The sleeve mesh 20 is provided with function expansion holes 20c and avoidance notches 20d, and both the function expansion holes 20c and the avoidance notches 20d communicate with the installation cavity 20b;

At the same time, an avoidance notch 20d is provided at the bottom of the sleeve mesh 20, and the avoidance notch can accommodate some buckle 301 structures. In this way, the buckle 301 structure is prevented from lifting the sleeve mesh 20, thereby reducing the adhesion tightness between the sleeve mesh 20 and the support frame 10; in another embodiment, the plastic housing 102 is provided with two positioning posts 103, and the two positioning posts 103 are arranged on the inner surface side of the plastic housing 102 facing the insertion port 20a. Correspondingly, the outer shell of the speaker is provided with a positioning channel for the positioning posts 103 to be inserted. Through the insertion fit of the positioning posts 103 and the positioning channel, the assembly yield of the electronic product can be improved; in yet another embodiment, the top of the plastic housing 102 is provided with a function expansion structure, and the function expansion structure includes a button 104, a sound outlet hole 10a, and an indicator light hole 10b. The button 104 corresponds to the touch unit of the speaker, so as to realize functions such as volume adjustment and start / stop control. The sound outlet hole 10a communicates with the inner cavity of the plastic housing to facilitate sound output, thereby increasing one sound outlet channel and realizing sound propagation in at least two directions. The indicator light hole 10b is used to insert the atmosphere light (such as an RGB lamp bead) of the electronic product to enhance the user experience of the product. It can be understood that the above three embodiments can be combined arbitrarily in terms of quantity to form electronic products with different functions.
