Description

Technical Field

[0001] The present application relates to the technical field of ceiling microphone products, and in particular to a fixing structure of an integrated mesh cover and a back cover of a ceiling microphone. Background Art

[0002] With the rapid development of conferencing systems and remote communication technologies, ceiling microphones ("ceiling mics") have become a mainstream feature in modern conference rooms and public spaces due to their high concealment, minimal desk space consumption, and multi-directional sound pickup. Ceiling mics not only effectively reduce the aesthetic impact of traditional microphones on conference rooms, but also, through clever mounting designs, meet the demands for efficient sound pickup and an elegant appearance. Consequently, they are widely used in smart offices, conference broadcasting, and audio and video transmission.

[0003] Existing ceiling microphones mostly use a split design, with the grille and front frame as separate components. The grille protects the internal sound pickup mechanism and is connected to the front frame via edge fixings; the front frame supports the grille and secures it to the rear cover. This split design allows for independent functionality of each component while adapting to varying production specifications. However, in practice, circular designs are becoming the mainstream choice for increased versatility and convenience, requiring a more compact design.

[0004] In existing designs, the separate grille and front frame not only increase the number of parts and manufacturing complexity, but also the extra space required by the mounting structure makes it difficult to achieve a smaller form factor for circular ceiling microphones. Therefore, the grille and front frame need to be integrated and fixed to the rear cover. However, even with this integrated grille and front frame design, the challenge remains to reliably secure the integrated grille to the rear cover. Utility Model Content

[0005] In order to achieve reliable fixation of the integrated mesh cover and the back cover based on the integrated design of the mesh cover and the front frame, the present application provides a fixing structure of the integrated mesh cover and the back cover of the ceiling microphone. The present application provides the following technical solutions:

[0006] A fixing structure for an integrated mesh cover and a back cover of a ceiling microphone comprises an integrated mesh cover, a back cover and a locking piece, wherein the integrated mesh cover and the back cover are both circular in design, and the side of the integrated mesh cover close to the back cover is bent inward to form a bent portion, and the bent portion is annular; a first through hole is provided on the back cover, a second through hole is provided on the bent portion, a rivet nut is provided in the second through hole, and the locking piece passes through the first through hole and the second through hole in sequence and is fixedly connected to the rivet nut.

[0007] In a specific embodiment, the locking member is a locking screw.

[0008] In a specific possible implementation manner, the locking member, the first through hole and the second through hole are each provided in plurality, and the plurality of the locking members, the first through holes and the second through holes are in one-to-one correspondence.

[0009] In a specific possible implementation manner, a plurality of the first through holes are evenly arranged on the circumference of the back cover, and a plurality of the second through holes are evenly arranged on the circumference of the bent portion.

[0010] In a specific possible implementation scheme, a first positioning hole is formed on the back cover, a second positioning hole is formed on the bent portion, and a positioning pin is passed through the first positioning hole.

[0011] In a specific possible implementation scheme, there are two of each of the first positioning hole, the second positioning hole, and the positioning pin, and the first positioning hole, the second positioning hole, and the positioning pin are in one-to-one correspondence.

[0012] In a specific possible implementation scheme, an annular bottom plate is provided on the inner wall of the bent portion located at the second through hole, and the top end of the rivet nut abuts against the top surface of the annular bottom plate.

[0013] In a specific possible implementation manner, the integrated mesh cover includes a cover body, and the cover body and the bent portion are of an integrated design.

[0014] In summary, the beneficial effects of this application include at least:

[0015] 1) In terms of the connection between the integrated mesh cover and the back cover, this application uses a combination of rivet nuts and locking parts. Since the inner bend of the integrated mesh cover can only be processed from one side, traditional screws or rivets cannot meet the requirements. By using rivet nuts, reliable fixation can be achieved even when the inner side of the bend is closed. The design of the rivet nut makes the connection process simpler and ensures the strength and stability of the connection. This not only solves the problem of achieving strong fixation in a limited space, but also simplifies the processing technology, improves production efficiency, and reduces working hours and production costs.

[0016] 2) The integrated grille design simplifies or eliminates the traditionally space-consuming fixed structure, resulting in a smaller and more streamlined product. This innovative design is particularly suitable for ceiling microphones, which are often mounted on ceilings or other locations with limited space. The inward-bending grille design eliminates interference from the fixed structure on the product's appearance, resulting in a more compact and sleek appearance, enhanced aesthetics, and flexibility to adapt to various installation environments. This design also enhances the product's versatility, allowing it to be used in a wide range of scenarios, such as conference rooms, classrooms, and sound systems.

[0017] This application proposes a structure for fixing an integrated ceiling microphone grille to a back cover, primarily comprising an integrated grille, a rivet nut, and a back cover. The integrated grille is formed by bending inward at the rear end to form a circular bend, with a through-hole provided in the bend. Due to limited processing conditions, it can only be operated from one side, so a rivet nut is selected. It can be processed from one side, enabling reliable fixation. The rivet nut engages with the through-hole in the back cover and is connected via a locking member, thereby firmly locking the back cover to the integrated grille.

[0018] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application and to implement it in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present application in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

[0024] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0027] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The embodiments of the present application disclose a fixing structure for an integrated mesh cover and a back cover of a ceiling microphone.

[0029] Reference Figure 1 A fixed structure of an integrated mesh cover and a back cover of a ceiling microphone, comprising an integrated mesh cover 2 and a back cover 1, both of which are circular in design. Figure 2 and Figure 3 The integrated mesh cover 2 includes a cover body 21, and the side of the cover body 21 close to the back cover 1 is bent inward to form a bending portion 22, and the bending portion 22 is annular. The cover body 21 and the bending portion 22 are an integrated structure. The integrated design eliminates the connection structure between the traditional split mesh cover and the front frame, reducing the number of parts and assembly steps. This simplifies the production process, reduces the process links, improves production efficiency, and reduces the complexity of assembly and transportation. In addition, by designing the cover body 21 and the bending portion 22 as an integrated structure, the problem of looseness that may occur in the connection of the two parts in the traditional design is avoided. This integrated design ensures the stability of the product, makes the connection between the integrated mesh cover and the back cover 1 more firm, thereby improving the overall structural strength of the product and avoiding loosening or damage during use.

[0030] Reference Figure 1 and Figure 2The integrated mesh cover 2 and the back cover 1 are fixedly connected by a plurality of locking members, which in this application are locking screws 3. Specifically, the back cover 1 is provided with a plurality of first through holes 11, which are evenly arranged on the circumference of the back cover 1. The bent portion 22 is provided with a plurality of second through holes 221, which are evenly arranged on the circumference of the bent portion 22. Each second through hole 221 is provided with a rivet nut 4, which is combined with the Figure 4 An annular base plate 23 is fixedly connected to the inner wall of the bent portion 22 at each second through-hole 221. The top of the rivet nut 4 abuts against the top surface of the annular base plate 23, thereby securing the rivet nut 4 within the second through-hole 221. There is a one-to-one correspondence between the locking screws 3, the first through-hole 11, and the second through-hole 221. Each locking screw 3 sequentially passes through its corresponding first through-hole 11 and second through-hole 221 and is fixedly connected to the rivet nut 4, thereby securing the integrated grille 2 to the back cover 1.

[0031] In practice, the rivet nut 4 is designed to be installed on the inside of the bend 22, which means that the installation can be completed through single-sided processing without the need for complex two-sided processing of the integrated mesh cover. The use of the rivet nut 4 simplifies the processing technology, reduces the complex steps required for assembly, and improves overall production efficiency. At the same time, the use of a standardized combination of locking screws 3 and rivet nuts 4 makes the installation process more efficient and convenient. By evenly arranging multiple through holes and locking screws 3 on the bend 22 and the back cover 1, not only the stability of the overall connection is improved, but also the design can be flexibly adapted to different product sizes and structural requirements. This structural design can adapt to the needs of different application scenarios while retaining sufficient degrees of freedom to optimize the product's appearance design and installation method.

[0032] Reference Figure 2The back cover 1 also has two first positioning holes 12, and the bent portion 22 has two corresponding second positioning holes 222. A positioning pin 5 is inserted into and fixed in each first positioning hole 12. The function of the positioning pin 5 is to precisely position the back cover 1 and the bent portion 22 of the integrated grille 2 by cooperating with the first positioning holes 12 and the second positioning holes 222. This design prevents misalignment or deviation during installation, ensuring that the integrated grille 2 and the back cover 1 always maintain the correct relative position during assembly, thereby ensuring the reliability of the fixed structure. The coordination of the positioning pin 5 and the positioning holes not only provides precise mechanical positioning, but also enhances the stability of the assembly process and reduces assembly errors caused by inaccurate positioning. In addition, the use of the positioning pin 5 and the positioning holes ensures that the back cover 1 and the integrated grille can be quickly aligned and accurately fixed during assembly. In this way, the connection between the back cover 1 and the integrated grille 2 is more precise and stable, avoiding errors that may occur during installation, improving assembly accuracy, and further enhancing the structural strength and stability of the product. In addition, this design simplifies the installation process, making the assembly process easier and more efficient.

[0033] In summary, the present application proposes a fixing structure for an integrated mesh cover and a back cover of a ceiling microphone, which mainly includes an integrated mesh cover 2, a rivet nut 4 and a back cover 1. The integrated mesh cover 2 is formed by an annular bending portion 22 through an inner bending at the rear end, and a through hole is provided in the bending portion 22. Due to the limited processing environment, it can only be operated from one side, so a rivet nut 4 is selected, which has the characteristic of being machinable from one side and can achieve reliable fixation. The rivet nut 4 cooperates with the through hole on the back cover 1 and is connected by a locking member, so that the back cover 1 and the integrated mesh cover are firmly locked. This solution not only solves the problem of fixing the integrated mesh cover 2 and the back cover 1, but also reduces the fixing structure and space limitations of the mesh cover and the front frame in the traditional split design, making the product appearance more free and compact, and simplifies the processing technology on the basis of ensuring the fixing strength, thereby improving the practicality and economy of the overall design.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
