[0003] However, the microphone in traditional technology needs to be fixed to the frame with an independent bracket. At least part of the bracket will protrude from the inner side of the frame and extend deep into the installation cavity, causing the problem of occupying the installation space inside the shell, and it cannot be applied to small-sized models. In addition, the structure of the bracket is complicated, so the microphone needs to be installed and fixed with the help of cushioning pads, pressing plates, multiple screws and other components. The installation uses a lot of materials and the assembly steps are complicated, which not only increases the processing cost but also reduces labor productivity. Summary of the invention

[0004] Based on this, it is necessary to provide a microphone installation structure and display device to address the problems of occupying installation space, high processing costs, and affecting production efficiency.

[0034] In order to make the above-mentioned purposes, 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. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0035] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0036] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0037] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0038] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0040] In order to enrich the functions of electronic class signs, some electronic class signs on the market are equipped with microphones for picking up sound. However, in traditional technology, the microphone needs to be fixed to the inside of the device using an independent bracket, which will take up more installation space and cannot be applied to small-sized models; in addition, the structure of the bracket is complicated, so the microphone can only be installed and fixed through components such as cushioning pads, pressing plates, and multiple screws. The installation uses a lot of materials and the assembly steps are complicated, which not only increases the processing cost, but also reduces labor production efficiency. In view of this, the present application proposes a microphone installation structure and display device 100 with a new structure to solve the above problems.

[0041] See also Figure 1 The present application provides a display device 100, which is specifically an electronic class sign. Exemplarily, the display device 100 includes a microphone mounting structure. Of course, the display device 100 is not limited to only including the microphone mounting structure, but should actually include functional components such as a rear shell, a control panel, and a display screen, which will not be described in detail here.

[0042] Please continue reading Figures 2 to 5 , which is a microphone mounting structure shown in an embodiment, includes a front shell 70, a frame 10, a mounting bracket 30 and a microphone assembly 40.

[0043] The frame 10 is specifically a rectangular frame made of a long strip of aluminum extrusion profile by integral bending. Therefore, the frame 10 includes a first splicing end 11 and a second splicing end 12. It can be understood that the first splicing end 11 and the second splicing end 12 are two free ends in the length direction of the frame 10. When the first splicing end 11 and the second splicing end 12 are butt-jointed and spliced, a structurally stable annular closed structure can be obtained.

[0044] The frame 10 is assembled to the inner side of the front shell 70 and forms a mounting cavity 80 with the front shell 70. The inner side wall of the frame 10 is provided with a first limiting portion 13 and a second limiting portion 14 protruding toward the mounting cavity 80. The first limiting portion 13 and the second limiting portion 14 cooperate to form a slot 20. Optionally, the first limiting portion 13 and the second limiting portion 14 are both plates protruding perpendicular to the thickness direction of the frame 10, and the two plates are parallel and spaced apart to form the slot 20.

[0045] Please continue reading Figure 6 and Figure 7 The mounting bracket 30 is clamped in the card slot 20, and the orthographic projection of the mounting bracket 30 in the direction of the front shell 70 falls into the card slot 20. The mounting bracket 30 includes a connecting component and a mounting portion 33 and a loading portion 34 connected thereto. The mounting portion 33 is assembled and fixed with the first limiting portion 13 through the connecting component; the microphone assembly 40 is mounted on the loading portion 34, and the orthographic projection of the microphone assembly 40 in the direction of the front shell 70 falls into the card slot 20.

[0046] It can be understood that the width of the slot 20 is matched with the width of the loading portion 34 , so that the mounting bracket 30 is not easily loosened and falls out after being pushed into the slot 20 .

[0047] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the microphone mounting structure of this solution specifically involves assembling the microphone assembly 40 onto the frame 10. During installation, the microphone assembly 40 is first mounted and fixed on the loading portion 34 of the mounting bracket 30 to be assembled into one with the mounting bracket 30. Thereafter, the combination of the mounting bracket 30 and the microphone assembly 40 is inserted into the slot 20 together. The slot 20 surrounded by the first limiting portion 13 and the second limiting portion 14 is engaged with the mounting bracket 30 to achieve pre-assembly and fixation. Finally, the mounting portion 33 of the mounting bracket 30 is connected and fixed to the first limiting portion 13 through a connecting assembly, thereby completing the processing content of assembling and fixing the microphone assembly 40 to the frame 10 through the mounting bracket 30.

[0048] Compared with the prior art, in the present solution, after the microphone assembly 40 is assembled to the inner side of the frame 10 through the mounting bracket 30, the mounting bracket 30 and the microphone assembly 40 have their orthographic projections in the direction of the front shell 70 fall into the card slot 20, so that the mounting bracket 30 and the microphone assembly 40 do not extend into the mounting cavity 80, thereby avoiding occupying the internal installation space of the device and being suitable for small-sized models to expand the scope of application. In addition, the mounting bracket 30 and the microphone assembly 40 can be fixed to the frame 10 only by the card connection of the card slot 20 and the installation of the connecting assembly. The installation structure is simple, uses less materials, helps to reduce processing costs, and simplifies the assembly process steps, which helps to improve production efficiency.

[0049] Please continue reading Figure 3 and Figure 5On the basis of the above embodiment, the frame 10 includes a first splicing end 11 and a second splicing end 12, the first splicing end 11 and the second splicing end 12 are butt-jointed, the connecting assembly includes a first connecting member 31 and a second connecting member 32, the mounting portion 33 is assembled and fixed to the first splicing end 11 through the first connecting member 31, and the mounting portion 33 is assembled and fixed to the second splicing end 12 through the second connecting member 32. The first limiting portion 13 and the second limiting portion 14 are arranged side by side and spaced apart along the width direction of the frame 10, and both the first limiting portion 13 and the second limiting portion 14 extend from the first splicing end 11 to the second splicing end 12.

[0050] Specifically, the first limiting portion 13 includes two parts of plate bodies, which are respectively formed on the inner side walls of the first splicing end 11 and the second splicing end 12; similarly, the second limiting portion 14 also includes two parts of plate bodies, which are respectively formed on the inner side walls of the first splicing end 11 and the second splicing end 12. When the first splicing end 11 and the second splicing end 12 are butt-jointed, the two parts of the plate bodies of the first limiting portion 13 and the second limiting portion 14 are closed together, so that the length of the first limiting portion 13 and the second limiting portion 14 can be extended, thereby ensuring that a sufficiently large contact area is formed between the mounting bracket 30, so that the mounting bracket 30 is more firmly clamped; in addition, the two parts of the plate bodies can also play the role of reinforcing ribs to improve the structural strength of the first splicing end 11 and the second splicing end 12, so that the first splicing end 11 and the second splicing end 12 are not easily deformed, which leads to an excessively large splicing seam and affects the appearance of the product.

[0051] Please continue reading Figure 3 and Figure 5 Furthermore, the first limiting portion 13 is provided with a first through hole 131 and a second through hole 132, and the first through hole 131 and the second through hole 132 are arranged at intervals along the length direction of the first limiting portion 13, and the first through hole 131 is located on the first splicing end 11, and the second through hole 132 is located on the second splicing end 12.

[0052] Correspondingly, the mounting portion 33 is provided with a first threaded hole 331 aligned with the first through hole 131, and a second threaded hole 332 aligned with the second through hole 132; the first connecting member 31 is provided as a first threaded component, the first threaded component is passed through the first through hole 131 and is screwed and fixed to the first threaded hole 331, and the second connecting member 32 is provided as a second threaded component, the second threaded component is passed through the second through hole 132 and is screwed and fixed to the second threaded hole 332. Therefore, the mounting bracket 30 can be more firmly fixed to the inner side of the frame 10 by the above-mentioned threaded locking method, and the first splicing end 11 and the second splicing end 12 can be spliced ​​more tightly and firmly, so as to prevent the splicing seam from being too large or uneven and affecting the product appearance and sealing protection performance.

[0053] Preferably, the first limiting portion 13 is provided with a recessed groove, and the first through hole 131 and the second through hole 132 are formed at the bottom of the recessed groove, so that after the first threaded component and the second threaded component are installed, the thread head is located in the recessed groove, thereby avoiding interference with the back shell when the frame 10 is assembled with the back shell.

[0054] Optionally, the first threaded component and the second threaded component may be any one of a screw, a bolt, etc., and may be selected according to actual needs.

[0055] Please continue reading Figure 4 and Figure 5 In addition, based on any of the above embodiments, the microphone assembly 40 includes a circuit board 41, the circuit board 41 is provided with a positioning hole 411, and the loading portion 34 is provided with a positioning column 341, and the positioning column 341 is inserted into the positioning hole 411. With the positioning column 341 inserted into the positioning hole 411, the circuit board 41 and the loading portion 34 can be assembled and fixed, that is, the microphone assembly 40 and the mounting bracket 30 are pre-assembled into one, so that the whole is conveniently inserted into the card slot 20, the number of parts (materials) can be reduced, and the assembly steps can be reduced, thereby improving production efficiency.

[0056] On the basis of the above embodiment, the preferred circuit board 41 is provided with two spaced positioning holes 411, and the loading portion 34 is provided with two spaced positioning posts 341, which are plugged and assembled with the positioning holes 411 in a one-to-one correspondence. The use of the plug-in structure design of two sets of positioning posts 341 and positioning holes 411 can, on the one hand, further improve the assembly strength of the microphone assembly 40 and the mounting bracket 30, and on the other hand, before being installed on the inner side of the frame 10, it can also limit the rotation of the microphone assembly 40 relative to the mounting bracket 30 to cause position deviation, thereby affecting the smoothness and effectiveness of the overall installation into the card slot 20.

[0057] In another embodiment, the microphone assembly 40 further includes a microphone body 42, which is disposed on the circuit board 41. Specifically, the microphone body 42 is electrically connected to the circuit board 41 by means of pins, welding, etc. The microphone body 42 is used to perform sound pickup, and the circuit board 41 is used to process the picked-up sound signal and transmit it to the control board for storage and other processing.

[0058] The loading portion 34 is provided with a first through hole 342, which is aligned with the microphone body 42. The frame 10 is provided with a sound pickup hole 15, which is aligned with the first through hole 342. The aligned first through hole 342 and the sound pickup hole 15 cooperate to form a sound pickup channel connected to the external environment, so that the microphone body 42 can perform normal sound pickup work.

[0059] The shape and size of the first through hole 342 and the sound pickup hole 15 can be adaptively selected according to the shape and size of the microphone body 42 , and thus are not specifically limited here.

[0060] Furthermore, the microphone mounting structure further includes a dustproof foam 50, which is installed in the first through hole 342 and is separated between the microphone body 42 and the sound pickup hole 15. The dustproof foam 50 can prevent dust in the external environment from contacting the sound pickup channel and accumulating on the surface of the microphone body 42 to cause blockage, thereby affecting the sound pickup effect of the microphone body 42.

[0061] In addition, based on any of the above embodiments, the microphone mounting structure further includes an adhesive member 60, and the circuit board 41 is bonded and fixed to the loading portion 34 through the adhesive member 60. Therefore, the circuit board 41 can be bonded and fixed to the surface of the loading portion 34 through the adhesive member 60, and the limiting effect formed by the overlapping positioning column 341 and the positioning hole 411 plugging together makes the assembly of the microphone assembly 40 and the mounting bracket 30 more stable.

[0062] Optionally, the adhesive member 60 may be a double-sided tape, or other adhesive components or mechanisms.

[0063] Furthermore, the adhesive member 60 is provided with a through hole 61 aligned with the positioning hole 411, and the positioning post 341 is inserted into the positioning hole 411 after passing through the through hole 61; the adhesive member 60 is also provided with a second through hole 62, and the second through hole 62 is aligned with the microphone body 42 and the first through hole 342. In this way, the adhesive member 60 will not interfere with the insertion of the positioning post 341 and the positioning hole 411, and ensure that the microphone body 42 is connected to the external environment through the sound pickup channel (composed of the first through hole 342, the second through hole 62 and the sound pickup hole 15), so that the sound pickup work can be performed normally.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
