[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] This utility model embodiment provides a conference microphone, such as... Figure 1 and Figure 2 As shown, the device includes a housing 10, a ring control circuit board 20, a speaker 30, and an antenna assembly 40. The housing 10 has a mounting cavity 101 and a sound outlet 102 communicating with the mounting cavity 101. The ring control circuit board 20 is disposed in the mounting cavity 101. The speaker 30 is disposed in the mounting cavity 101 and is located in the ring control circuit board 20 and electrically connected to the ring control circuit board 20. The sound from the speaker 30 diffuses outward along the sound outlet 102. The antenna assembly 40 is disposed on the top of the housing 10 near the ring control circuit board 20 and includes at least a first antenna 410 and a second antenna 420 that are independently disposed. Both the first antenna 410 and the second antenna 420 are electrically connected to the ring control circuit board 20.

[0019] The mounting cavity 101 formed within the outer casing 10 is used to accommodate the internal components of the conference microphone. The speaker 30 and the ring control circuit board 20 are both located within the mounting cavity 101. The sound from the speaker 30 propagates outward along the sound outlet 102. The ring control circuit board 20 serves as the control core of the conference microphone, controlling the sound output of the speaker 30 and the signal transmission and reception of the antenna assembly 40. The antenna assembly 40 includes at least two independent antennas, a first antenna 410 and a second antenna 420, both of which are electrically connected to the ring control circuit board 20. This means that the first antenna 410 and the second antenna 420 can work independently without interfering with each other, and both can process and transmit signals through the ring control circuit board 20. This allows the conference microphone to support at least two different wireless communication modes simultaneously, enabling it to flexibly adapt to different wireless communication scenarios, no longer limited to a single mode, greatly expanding the applicability of the conference microphone and meeting diverse usage needs.

[0020] As a preferred embodiment of this invention, such as Figures 1 to 3 As shown, the outer shell 10 includes a bottom shell 110 and an upper shell 120 that are interlocked. The bottom shell 110 and the upper shell 120 enclose a mounting cavity 101. The sound outlet 102 is located on the upper shell 120. A sound guide groove 103 communicating with the sound outlet 102 is also formed on the side of the upper shell 120 away from the bottom shell 110. A sound guide plate 122 is disposed in the sound guide groove 103. The first antenna 410 and the second antenna 420 are both attached to the side of the upper shell 120 near the annular control circuit board 20, and the first antenna 410 and the second antenna 420 both extend to the back of the sound guide groove 103.

[0021] The outer shell 10 consists of a bottom shell 110 and an upper shell 120 that interlock, forming a mounting cavity 101. The sound outlet 102 is located on the upper shell 120. This split design of the outer shell 10 facilitates the installation and maintenance of internal components. On the side of the upper shell 120 away from the bottom shell 110, there is a sound guide groove 103 communicating with the sound outlet 102. A sound guide plate 122 is disposed within the sound guide groove 103. The sound guide groove 103 and the sound guide plate 122 guide the sound emitted by the speaker 30, enhancing the sound propagation effect. The first antenna 410 and the second antenna 420 are both attached to the side of the upper shell 120 near the annular control circuit board 20 and extend to the back of the sound guide groove 103. This installation method makes full use of the space of the upper shell 120, making the layout of the antenna assembly 40 more compact. While ensuring that the first antenna 410 and the second antenna 420 have a large area, it does not hinder the setting of other structures, thus improving signal transmission performance.

[0022] Meanwhile, the antenna assembly 40 is attached to the upper shell 120, ensuring a secure connection between the antenna assembly 40 and the upper shell 120. This prevents the antenna assembly 40 from becoming loose and affecting signal transmission, thus guaranteeing the stability of the antenna assembly 40's operation. Furthermore, this structural design makes the overall structure of the conference microphone more compact, facilitating its promotion and use.

[0023] In this embodiment, refer to Figure 1 and Figure 2 A cover plate 12 is provided on the side of the upper shell 120 away from the bottom shell 110. A through hole 105 is formed on the cover plate 12, and the sound diffuses outward along the through hole 105.

[0024] As a preferred embodiment, refer to Figure 3 The upper shell 120 has a positioning groove 104 formed on the side near the bottom shell 110. The top of the speaker 30 and the sound outlet 102 are both located in the positioning groove 104. The first antenna 410 includes a first straight portion 411 and a first arc portion 412 connected to each other. The second antenna 420 includes a second straight portion 421 and a second arc portion 422 connected to each other. The first straight portion 411 and the second straight portion 421 are both attached to the smooth part of the upper shell 120. The first arc portion 412 and the second arc portion 422 are both attached to the arc of the sound guide groove 103 and abut against the positioning groove 104.

[0025] The upper shell 120 has a positioning groove 104 on the side near the bottom shell 110. The top of the speaker 30 and the sound outlet 102 are located in the positioning groove 104. The positioning groove 104 fixes and positions the speaker 30, ensuring that the speaker 30 is installed in an accurate position and preventing displacement due to vibration or other reasons during use, which would affect the sound output. At the same time, the first straight part 411 and the second straight part 421 are attached to the smooth part of the upper shell 120, and the first arc part 412 and the second arc part 422 are attached to the arc of the sound guide groove 103 and abut against the positioning groove 104. This allows the first antenna 410 and the second antenna 420 to better adapt to the shape of the upper shell 120. In particular, the arc structure of the sound guide groove 103 ensures that the antenna assembly 40 has a larger area, improving signal transmission performance and making the antenna assembly 40 fit more tightly with the upper shell 120, resulting in a more stable installation.

[0026] As a preferred embodiment, refer to Figure 3 The positioning slot 104 has an elongated shape, and the first antenna 410 and the second antenna 420 are located on the outer sides of the adjacent two sides of the positioning slot 104, respectively.

[0027] The positioning slot 104 has a rectangular structure, which better fits the shape of the speaker 30, ensuring the stability of the speaker 30 installation. The first antenna 410 and the second antenna 420 are located on the outer sides of adjacent sides, ensuring the independent setting of the first antenna 410 and the second antenna 420. This effectively avoids signal interference between the first antenna 410 and the second antenna 420. At the same time, this layout makes the antenna assembly 40 more evenly distributed in a limited space, enabling more comprehensive signal reception and transmission, and improving wireless communication performance.

[0028] As a preferred embodiment of this invention, such as Figures 1 to 3 As shown, a power supply 50 electrically connected to the annular control circuit board 20 is also provided in the mounting cavity 101. The power supply 50 is located on the side of the positioning groove 104 away from the first antenna 410, and the second antenna 420 is located on the side of the positioning groove 104 away from the power supply 50.

[0029] The mounting cavity 101 contains a power supply 50 that is electrically connected to the ring control circuit board 20, providing power support for the various components of the conference microphone. During operation, the power supply 50 will generate electromagnetic interference, which will affect the signal transmission and reception of the antenna assembly 40. By placing the first antenna 410 on the side away from the power supply 50 and the second antenna 420 on the side away from the power supply 50, the electromagnetic interference of the power supply 50 on the antenna can be minimized, ensuring that the antenna can work stably and efficiently, thereby improving the performance of the conference microphone.

[0030] As a preferred embodiment, the first antenna 410 and the second antenna 420 are any two of the following: a WIFI antenna, a Bluetooth antenna, and a mobile network antenna.

[0031] Among them, Wi-Fi, Bluetooth, and mobile networks are commonly used wireless communication methods, and different scenarios may require different communication methods. For example, in a conference room with Wi-Fi, the microphone can connect to a computer via a Wi-Fi antenna; in the absence of Wi-Fi, it can connect to a mobile phone via a Bluetooth antenna; in outdoor remote meetings, communication may require a mobile network antenna. This embodiment does not specifically limit the type combination of the first antenna 410 and the second antenna 420. For example, the first antenna 410 can be a Bluetooth antenna and the second antenna 420 a Wi-Fi antenna; or, the first antenna 410 can be a Bluetooth antenna and the second antenna 420 a mobile network antenna; or, the first antenna 410 can be a Wi-Fi antenna and the second antenna 420 a mobile network antenna. These settings further enhance the flexibility and adaptability of the microphone, enabling it to function normally in various complex communication environments and meeting the usage needs of different users in different scenarios.

[0032] As a preferred embodiment, refer to Figure 3 and Figure 4 Both the first antenna 410 and the second antenna 420 are electrically connected to the ring circuit board via wires 60.

[0033] The use of wire 60 to connect the antenna assembly 40 and the ring circuit board ensures a stable and reliable electrical connection between the antenna assembly 40 and the ring circuit board, reduces signal loss during transmission, and guarantees the performance of the first antenna 410 and the second antenna 420.

[0034] As a preferred embodiment, Figure 2 and Figure 4 The upper shell 120 has a plurality of first snap-fit ​​portions 121 arranged circumferentially on the side near the bottom shell 110, and the inner wall of the bottom shell 110 has a plurality of second snap-fit ​​portions 111 arranged circumferentially. The first snap-fit ​​portions 121 and the second snap-fit ​​portions 111 are connected in a one-to-one snap-fit ​​manner. The first straight portion 411 and the second straight portion 421 maintain a preset installation distance from the first snap-fit ​​portions 121.

[0035] The snap-fit ​​connection allows the bottom shell 110 and the top shell 120 to be quickly and securely fastened together. The first straight part 411 and the second straight part 421 maintain a preset distance from the first snap-fit ​​part 121 in order to avoid the first snap-fit ​​part 121 from affecting the first antenna 410 and the second antenna 420, and to prevent the antenna assembly 40 from being damaged during the installation of the outer shell 10, so as to ensure that the wireless communication performance of the conference microphone is not affected by the assembly of the outer shell 10.

[0036] As a preferred embodiment, refer to Figure 4 and Figure 5 The outer wall of the first snap-fit ​​part 121 is formed with a snap-fit ​​groove 1211 and a guide slope 1212, and the second snap-fit ​​part 111 can slide into the snap-fit ​​groove 1211 along the guide slope 1212.

[0037] The guide ramp 1212 makes the bottom shell 110 and top shell 120 easier and smoother to fasten together, reducing wear on components during installation and improving assembly efficiency. The snap-fit ​​groove 1211 can firmly fix the second snap-fit ​​part 111, ensuring the stability of the connection of the outer shell 10 and preventing the bottom shell 110 and top shell 120 from loosening or separating during use, thereby protecting the internal components from damage and extending the service life of the conference microphone.

[0038] At the same time, the above-mentioned connection structure also avoids the impact of the first snap-fit ​​part 121 on the setting of the antenna assembly 40 as much as possible, ensuring the performance of the antenna assembly 40.

[0039] As a preferred embodiment, refer to Figure 2 , Figure 6 and Figure 7 The inner wall of the bottom shell 110 is also provided with a flexible circuit board 710 and a microphone 720 disposed on the flexible circuit board 710. The flexible circuit board 710 is electrically connected to the ring control circuit board 20. The inner wall of the bottom shell 110 is also provided with a support block 112 opposite to the second snap-fit ​​part 111 in the circumferential direction. The flexible circuit board 710 is supported between the second snap-fit ​​part 111 and the support block 112. A buffer pad 730 and a reinforcing plate 740 are stacked on the side of the microphone 720 near the bottom shell 110. A sound hole 701 opposite to the microphone 720 is formed on the inner wall of the bottom shell 110.

[0040] The use of the flexible circuit board 710 allows for more flexible installation of the microphone 720, better adapting to the spatial layout of the mounting cavity 101 and ensuring accurate sound reception. The buffer pad 730 reduces the impact of vibrations during use on the microphone 720, preventing vibration-induced noise and improving the clarity of sound pickup. The reinforcing plate 740 prevents the microphone 720 from deforming or shifting due to external forces, ensuring its operational stability. The sound hole 701 is positioned opposite the microphone 720, allowing sound to enter the microphone 720 more directly, reducing sound loss and interference, further improving the microphone 720's sound pickup effect, and ensuring that the other party can clearly hear the meeting content during remote conferences.

[0041] The aforementioned flexible circuit board 710 is held between the second snap-fit ​​portion 111 and the holding block 112, making full use of the internal space of the outer shell 10, improving the overall integration of the conference microphone, and facilitating the use and promotion of the conference microphone.
