[0036] like Figures 1 to 3As shown, in one embodiment of the utility model, the conference terminal device 100 includes a shell 10, a sound-emitting component 20 and a core board component 30. The shell 10 includes a bottom shell 11 and an upper cover 12. The upper cover 12 is detachably connected with the bottom shell 11 to form a receiving cavity 13. The upper cover 12 is provided with a sound pickup hole 121; the sound-emitting component 20 includes a mounting seat 21 and a speaker 22. The mounting seat 21 is fixed in the receiving cavity 13. The speaker 22 is mounted on the mounting seat 21. The sound-emitting end of the speaker 22 is arranged toward the upper cover 12; the core board component 30 includes a first core board 31, a second core board 32 and a flexible circuit board 33, the first core board 31 and the second core board 32 are respectively arranged at the two ends of the mounting base 21, and the first core board 31 is connected to the upper cover 12, and the first core board 31 is integrated with a pickup 342 and an operation button 341 on the side facing the upper cover 12, the operation button 341 passes through the upper cover 12, and the pickup 342 is arranged opposite to the pickup hole 121; the second core board 32 is connected to the bottom shell 11, the speaker 22 is electrically connected to the second core board 32, one end of the flexible circuit board 33 is electrically connected to the first core board 31, and the other end bypasses the mounting base 21 and is electrically connected to the second core board 32.

[0037] In the above embodiment, the second core board 32 is first fixed on the bottom shell 11, and then the flexible circuit board 33 and the second core board 32 are connected, and then the sound-emitting component 20 is fixed on the bottom shell 11; at the same time, the first core board 31 is fixed on the upper cover 12, and then the flexible circuit board 33 is connected to the first core board 31, and finally the upper cover 12 and the bottom shell 11 are assembled to complete the assembly of the entire conference terminal device 100.

[0038] In this embodiment, there are two core plate structures, the first core plate 31 and the second core plate 32. The pickup 342 and the operation button 341 can be directly integrated on the first core plate 31, and the power line and the like can be connected to the second core plate 32. The first core plate 31 and the second core plate 32 are connected by a flexible circuit board 33, which reduces the use of wires and can make the internal structure simple and clear. When disassembling and assembling, there is no need to worry about touching the wires. In addition, compared with using wires to connect the electrical components 321 and the core plate, directly welding the electrical components 321 and integrating them in the first core plate 31 and the second core plate 32 can make the connection of the electrical components 321 simpler and more reliable.

[0039] In order to further assemble the conference terminal device 100, connecting terminals are provided at both ends of the flexible circuit board 33, and end seats are provided on the first core board 31 and the second core board 32. The power transmission and signal transmission between the first core board 31 and the second core board 32 can be completed by plugging the connecting terminals into the corresponding end seats.

[0040] like Figure 3As shown, in some embodiments, the inner circumference of the bottom shell 11 forms a step portion 111, and the mounting seat 21 is fixed to the step portion 111; the mounting seat 21 has a mounting portion 211 protruding toward the upper cover 12, and the mounting portion 211 is provided with a mounting groove 212, and the speaker 22 is arranged in the mounting groove 212. The mounting groove 212 is adapted to the shape of the speaker 22, forming an effect similar to reverse mold installation, raising the sound field, obtaining a better sense of hearing, increasing the depth and breadth of the sound field, positioning the sound field, and reducing unnecessary sound energy loss caused by refraction and reflection.

[0041] The speaker 22 can be a dynamic coil sound unit, a moving iron sound unit or an electrostatic sound unit. The upper cover 12 is provided with a sound outlet, and the front sound cavity of the speaker 22 is directly opposite to the sound outlet.

[0042] Based on the above embodiment, during the setting, there is a gap between the end of the mounting portion 211 and the upper cover 12, and a buffer member 51 is provided between the mounting portion 211 and the upper cover 12. The buffer member 51 can have a certain amount of pre-compression so that the mounting seat 21 can be more stably installed on the bottom shell 11.

[0043] Please refer to Figures 3 to 5 In order to avoid the mounting portion 211 of the mounting seat 21, the first core plate 31 is an annular structure, and the first core plate 31 is arranged at the periphery of the mounting portion 211. That is, the mounting portion 211 passes through the hollow part of the first core plate 31. It can be understood that the first core plate 31 is connected to the upper cover 12, and there is a gap between the bottom surface and the inner edge of the first core plate 31 and the mounting portion 211, and a buffer 51 is arranged between the mounting portion 211 and the upper cover 12, which can absorb the vibration of the speaker 22 when making a sound, thereby reducing the impact on the pickup 342 on the first core plate 31.

[0044] In some embodiments, the upper cover 12 is provided with a first positioning column 122, and a first positioning hole 311 is provided on the first core plate 31, and the first positioning column 122 passes through the first positioning hole 311. When assembling the upper cover 12 and the first core plate 31, the installation position of the first core plate 31 is determined by the cooperation between the first positioning column 122 and the first positioning hole 311, so as to ensure that the operation button 341 and the pickup 342 can be aligned with the installation space reserved on the upper cover 12 and the pickup hole 121. The first core plate 31 is pressed until it is tightly against the upper cover 12, and then the first core plate 31 is fixed to the upper cover 12 by fasteners such as bolts.

[0045] Based on the above embodiments, please refer to Figure 6 and Figure 7 In order to further improve the audio collection effect, the outer periphery of the sound pickup 342 is covered with a shock-absorbing silicone 41, and the shock-absorbing silicone 41 is provided with a through hole 412 connected to the sound pickup hole 121. The shock-absorbing silicone 41 can reduce the influence of the vibration generated by the speaker 22 on the sound pickup 342, further improving the accuracy of the sound pickup 342 in collecting audio information.

[0046] The upper cover 12 is provided with a limiting groove 123, and the sound pickup hole 121 is located on the top wall of the limiting groove 123; the shock-absorbing silicone rubber 41 has a mounting protrusion 411, and the mounting protrusion 411 is inserted into the limiting groove 123. The limiting groove 123 cooperates with the mounting protrusion 411 to further position the installation position of the sound pickup 342 separately, thereby improving the position accuracy of the through hole 412 on the shock-absorbing silicone rubber 41, the sound pickup hole 121 on the upper cover 12, and the sound pickup 342. And directly cooperating with the shock-absorbing silicone rubber 41, it can prevent the shock-absorbing silicone rubber 41 and the upper cover 12 from shifting during use.

[0047] Similarly, a limiting groove 123 can also be opened on the shock-absorbing silicone rubber 41, and the limiting groove 123 is located at the periphery of the pickup 342. By setting a mounting protrusion 411 on the inner wall of the upper cover 12, the mounting protrusion 411 can be inserted into the limiting groove 123 to limit the installation position of the shock-absorbing silicone rubber 41 and the upper cover 12.

[0048] In some embodiments, please refer again to Figure 5 The core board assembly 30 includes a light-emitting structure 35, which can pass through the upper cover 12 to serve as an indicator light or a decoration. The number of the light-emitting structures 35 can be multiple, and the multiple light-emitting structures 35 are arranged at intervals along the circumference of the mounting portion 211. The number of the light-emitting structures 35 can also be one, and the present application does not limit the number of the light-emitting structures 35. The portion of the light-emitting structure 35 exposed from the upper cover 12 can be in a dot-shaped, strip-shaped, or ring-shaped shape, and the present application does not limit the shape of the portion of the light-emitting structure 35 exposed from the upper cover 12.

[0049] The light emitting structure 35 includes a light source 351, a first light guide 352 and a second light guide 353. The first light guide 352 is attached to the first core board 31. One end of the second light guide 353 is connected to the first light guide 352, and the other end passes through the upper cover 12. The light source 351 is arranged on one side of the first light guide 352 and is electrically connected to the first core board 31. That is, the light source 351 emits light horizontally, the light incident surface of the first light guide 352 is arranged directly opposite to the light source 351, and the second light guide 353 is arranged vertically to the first light guide 352. Through the vertical first light guide 352 and the second light guide 353, light can be transmitted evenly from the part of the second light guide 353 exposed from the upper cover 12, and the light emission effect is softer.

[0050] The outer periphery of the second light guide 353 is convexly disposed on the limiting protrusion, and the limiting protrusion can be tightly pressed against the upper cover 12 to limit the depth of the second light guide 353 inserted into the upper cover 12 .

[0051] In other embodiments, the light emitting structure 35 may not include the first light guide 352, the bottom of the second light guide 353 is grooved, the light source 351 is disposed on the first core board 31 and electrically connected to the first core board 31, the second light guide 353 covers the light source 351, and the groove at the bottom of the second light guide 353 is just enough to accommodate the light source 351. The light source 351 emits light vertically, which can improve the brightness and color splendour of the part of the second light guide 353 exposed on the upper cover 12.

[0052] Different light-emitting structures 35 may be selected according to different requirements, and this application does not limit this.

[0053] In some embodiments, the second core plate 32 is spaced apart from the mounting seat 21, and the electrical components 321 are integrated on the side of the second core plate 32 away from the mounting seat 21. A certain gap is reserved between the second core plate 32 and the mounting seat 21, and the electrical components 321 are arranged on the side of the second core plate 32 away from the mounting seat 21, so that the electrical components 321 can avoid interference with the mounting seat 21.

[0054] The electrical components 321 can be welded together after being inserted into the connection holes on the second core plate 32 by pins, and the gap between the second core plate 32 and the mounting seat 21 can accommodate the pins. The electrical components 321 can also be attached to the feeding points on the surface of the second core plate 32 and then welded.

[0055] The present application can also avoid integrating too many electrical components 321 on the core board by providing the first core board 31 and the second core board 32 .

[0056] In one embodiment, please refer again to Figure 2 , Figure 3 and Figure 5 The bottom shell 11 is provided with a supporting rib 112, the top of the supporting rib 112 has a supporting surface 1121 and a stop surface 1122, the second core plate 32 is supported on the supporting surface 1121, and the edge of the second core plate 32 is limited to the stop surface 1122. The supporting surface 1121 limits and stops the bottom plate of the second core plate 32, and the stop surface 1122 limits and stops the edge of the second core plate 32, thereby limiting the position of the second core plate 32. After the second core plate 32 is limited, the second core plate 32 is fixed to the bottom shell 11 by fasteners such as bolts.

[0057] There are multiple supporting ribs 112 , and the multiple supporting ribs 112 are arranged along the outer edge of the second core plate 32 .

[0058] It is understandable that a second positioning hole can also be opened on the second core plate 32, and a second positioning column can be set on the bottom shell 11. The supporting ribs 112 only play the role of supporting the second core plate 32, and the second positioning column is inserted into the second positioning hole to limit the second core plate 32.

[0059] In order to improve the strength of the support ribs 112 and ensure their supporting effect, reinforcing ribs can be set on the sides of the support ribs 112, and the tops of the reinforcing ribs can be flush with the supporting surfaces 1121, thereby improving the strength of the support ribs 112 and simultaneously playing a supporting role together with the support ribs 112.

[0060] During use, by placing the conference terminal device 100 on a desktop, the bottom shell 11 plays a supporting role. In order to improve the structural strength of the bottom shell 11 , cross-arranged reinforcing ribs may be provided on the inner wall of the bottom shell 11 .

[0061] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
