[0003] However, for microphones with wireless capabilities, wireless signal transmission is achieved through a built-in antenna, and the metal casing, due to its shielding effect on electromagnetic waves, can easily interfere with the signal transmission of the internal antenna.

[0004] In view of the above-mentioned existing situation, this application provides a wireless microphone that can improve the problem of wireless signal interference in microphones with metal housings.

[0005] The present invention provides a microphone, comprising: a housing made of metal; a cover fitted to the bottom of the housing, the cover having a wave-transparent structure, the housing and the cover forming an installation space, the installation space containing a circuit board; a separator connected to the housing and extending toward the cover, the separator dividing the installation space into a first space and a second space, the separator being made of metal; a first antenna disposed on the circuit board, the first antenna being located in the first space; and a second antenna disposed on the circuit board, the second antenna being located in the second space; wherein the first antenna and the second antenna correspond to the wave-transparent structure, the wave-transparent structure being used to provide a channel for the transmission of wireless audio signals.

[0006] Optionally, the housing includes an outer shell and a bottom plate connected to each other, the bottom plate being disposed inside the outer shell and near the bottom of the outer shell, and the bottom plate being located between the outer shell and the shell cover; the partition is connected to the bottom plate and extends toward the shell cover.

[0011] Optionally, the cover has a window, the opening position of which corresponds to the first antenna and the second antenna. The wave-transparent structure also includes a wave-transparent element, which is embedded in the window and can provide a channel for the transmission of wireless audio signals.

[0012] Optionally, the microphone includes an inner frame and a battery, the battery being connected to the inner frame; one end of the inner frame facing the housing is connected to the separator, and the inner frame and the separator are integrally formed.

[0013] Optionally, the outer shell is integrally formed with the base plate, and the base plate has a cleaning hole; the outer shell also includes a metal sheet, which is connected to the base plate, and the base plate covers the cleaning hole.

[0014] Optionally, the metal sheet includes a cover portion and a partition portion connected to each other; the cover portion is connected to the base plate by screws, and the cover portion covers the cleaning hole; the partition portion is located at the end of the partition member facing the inner wall of the housing, and the partition portion abuts against the partition member and the inner wall of the housing respectively.

[0015] The microphone of this invention includes a housing, a cover, a separator, a first antenna, and a second antenna. The housing is made of metal.

[0027] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions.

If the specific posture changes, the directional indications will also change accordingly.

[0028] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0029] Reference Figures 1 to 4 This application provides a microphone, which includes a housing 1, a cover 2, a separator 4, a first antenna 5, and a second antenna 6. The housing 1 is made of metal; the cover 2 is fitted onto the bottom of the housing 1 and has a wave-transparent structure. The housing 1 and the cover 2 enclose an installation space, within which a circuit board 3 is disposed; the separator 4 is connected to the housing 1 and extends toward the cover 2, dividing the installation space into a first space 11 and a second space 12. The separator 4 is made of metal; the first antenna 5 is disposed on the circuit board 3 and is located in the first space 11; the second antenna 6 is disposed on the circuit board 3 and is located in the second space 12; wherein, the first antenna 5 and the second antenna 6 correspond to the wave-transparent structure, which provides a channel for the transmission of wireless audio signals.

[0030] According to the above structure, in the microphone provided in this application, the housing 1 is made of metal, which enables the microphone to have high structural strength, effectively resisting damage caused by drops or collisions, improving the microphone's durability, and extending its service life. Furthermore, the metal material of the microphone provides a high-end feel, making it more suitable for high-end conference environments and other occasions where high aesthetic requirements exist for the microphone. In addition, the microphone in this application is equipped with a first antenna 5 and a second antenna 6. The dual-antenna setup improves signal transmission efficiency. The first antenna 5 and the second antenna 6 transmit wireless audio signals through a wave-transparent structure. A metal separator 4 is also provided inside the microphone to form an electromagnetic barrier between the first antenna 5 and the second antenna 6. The first space 11 and the second space 12 separated by the separator 4 form two relatively independent spaces, effectively isolating the radiation field between the first antenna 5 and the second antenna 6 and reducing signal interference between the two antennas. Therefore, the microphone in this application, while retaining the high structural strength and high-end feel of the metal housing 1, also introduces a dual-antenna structure, thereby significantly improving signal transmission efficiency.

[0031] Reference Figures 3 to 6 In some embodiments, the housing 1 includes an outer shell 13 and a bottom plate 14 connected to each other. The bottom plate 14 is disposed inside the outer shell 13 and near the bottom of the outer shell 13, and is located between the outer shell 13 and the cover 2. A partition 4 is connected to the bottom plate 14 and extends toward the cover 2. Thus, the bottom plate 14 can cooperate with the partition 4, which can be regarded as a top plate that can cover the top of the first space 11 and the second space 12, thereby increasing the independence between the first space 11 and the second space 12. Specifically, one side of the partition 4 and a portion of the bottom plate 14 enclose the first space 11, and the other side of the partition 4 and another portion of the bottom plate 14 enclose the second space 12.

[0032] Reference Figure 4 In some embodiments, the circuit board 3 and the base plate 14 are spaced apart. On one hand, the space formed between the circuit board 3 and the base plate 14 provides necessary space for the near-field radiation of the antenna, optimizing the performance of the first antenna 5 and the second antenna 6. On the other hand, the circuit board 3 generates heat during operation, and the space between the circuit board 3 and the base plate 14 serves as a heat dissipation space, effectively dissipating the heat generated by the circuit board 3 during operation and preventing heat accumulation from affecting the performance of the circuit board 3, thereby improving the stability and lifespan of the circuit board 3.

[0033] In some embodiments, a central control circuit board is also provided inside the housing, and the circuit board 3 located in the installation space is connected to the central control circuit board via a connecting wire.

[0034] In some embodiments, the end of the separator 4 facing away from the base plate 14 is connected to the circuit board 3. Specifically, the circuit board 3 and the separator 4 are connected by screws.

[0035] Reference Figure 3 and Figure 4 In some embodiments, the partition 4 is perpendicular to the circuit board 3, and the circuit board 3 is parallel to the cover 2. Thus, the partition 4 and the circuit board 3 are neatly and orderly distributed within the installation space, facilitating the arrangement of internal wiring, improving overall space utilization, and also promoting effective heat dissipation and enhancing heat dissipation efficiency.

[0036] In some implementations, the cover 2 is made of a wave-transparent material, providing a channel for the transmission of wireless audio signals. Thus, the cover 2 as a whole can function as a wave-transparent structure, allowing the wireless signals of the first antenna 5 and the second antenna 6 to be transmitted through the entire cover 2.

[0037] In some embodiments, the cover 2 has a window, the opening position of which corresponds to the first antenna 5 and the second antenna 6. This window then serves as a wave-transparent structure, through which wireless signals are transmitted. In this embodiment, the cover 2 can be made of metal or a wave-transparent material.

[0038] In some embodiments, the cover 2 has a window, the opening position of which corresponds to the first antenna 5 and the second antenna 6. The wave-transparent structure also includes a wave-transparent element embedded in the window, which provides a channel for the transmission of wireless audio signals. Specifically, the wave-transparent element can be made of a wave-transparent material. Thus, the wave-transparent element can block the window, preventing external dust and moisture from entering through the window, and since the wave-transparent element is made of a wave-transparent material, it does not affect the transmission of wireless signals. In this embodiment, the cover 2 can be made of metal or a wave-transparent material.

[0039] In some examples, the wave-transparent material can be made of plastics, such as ABS plastic and polycarbonate, which are lightweight and low-cost. In other examples, the wave-transparent material can also be made of ceramic materials, such as alumina ceramics, which have high strength and heat resistance, as well as good wave-transparent performance. In still other examples, the wave-transparent material can also be made of silicone or rubber. In applications involving wave-transparent components, these materials can also provide good sealing effects to better block windows.

[0040] In some embodiments, the microphone includes an inner frame 9 and a battery 8, with the battery 8 connected to the inner frame 9. The end of the inner frame 9 facing the housing 2 is connected to a separator 4, and the inner frame 9 and separator 4 are integrally formed. Thus, the separator 4 can also be considered a natural extension of the inner frame 9; the portion of the inner frame 9 extending into the installation space is the separator 4. Therefore, the inner frame 9 not only provides connection and support for the battery 8 but also serves as a separator within the installation space, possessing a dual function. This avoids the fragmentation and complexity of the microphone's internal components and improves the overall structural strength. Furthermore, the integrally formed inner frame 9 and separator 4 make the entire microphone structure more compact, saving internal space, and the integrated structure reduces connection points, lowering the risk of failure due to poor connections.

[0041] In some embodiments, the end of the partition 4 facing away from the base plate 14 is connected to the circuit board 3. Alternatively, it can be considered as the circuit board 3 being connected to the portion of the inner frame 9 extending into the mounting space. The inner frame 9 and the partition 4 can be spaced apart from the outer casing 13. Therefore, the circuit board 3 does not directly contact the outer casing 13, and vibrations transmitted through the outer casing 13 are transmitted to the inner frame 9 with minimal impact, thereby reducing the influence of external vibrations on the circuit board 3.

[0042] In some embodiments, the outer shell 13 and the base plate 14 are integrally formed, and the base plate 14 has a cleaning hole 141. The shell 1 also includes a metal sheet 7, which is connected to the base plate 14 and covers the cleaning hole 141. Specifically, during the microphone installation process, glue is used to connect other internal electronic components. When applying glue, some glue may fall inside the shell 1, requiring a glue removal machine to clean the fallen glue. To facilitate cleaning, a cleaning hole 141 is provided in this embodiment. Thus, in this embodiment, the cleaning hole 141 provides an entry channel for the glue removal machine head, facilitating the removal of fallen glue. After completing the glue removal process, the operator uses the metal sheet 7 to cover the cleaning hole 141, so that the base plate 14 can still form a closed whole, better covering the top of the first space 11 and the second space 12, allowing the first space 11 and the second space 12 to still form two relatively independent spaces.

[0043] In some embodiments, the metal sheet 7 can also overlap with the base plate 14. Thus, the metal sheet 7 not only covers the cleaning hole 141, but also covers the base plate 14. Consequently, the top of the first space 11 and / or the second space 12 can have a two-layer metal shielding structure, further enhancing the independence between the first space 11 and the second space 12, strengthening the electromagnetic barrier formed between the first antenna 5 and the second antenna 6, and reducing signal interference between the two antennas.

[0044] Specifically, in some examples, the metal sheet 7 may overlap only with the portion of the base plate 14 located in the first space 11, the metal sheet 7 may overlap only with the portion of the base plate 14 located in the second space 12, or the metal sheet 7 may completely overlap with the entire base plate 14.

[0045] In some examples, the cleaning hole 141 can be opened in a trapezoidal shape.

[0046] In some embodiments, the metal sheet 7 includes a cover portion 71 and a partition portion 72 connected to each other; the cover portion 71 is connected to the base plate 14 by screws, and the cover portion 71 covers the cleaning hole 141; the partition portion 72 is located at the end of the partition member 4 facing the inner wall of the housing 1, and the partition portion 72 abuts against the partition member 4 and the inner wall of the housing 1 respectively. Specifically, after the glue removal process is completed, the operator can use screws to connect the cover portion 71 to the base plate 14, and at this time the partition portion 72 can be located at the end of the partition member 4. In this embodiment, the partition portion 72 can further enhance the isolation between the first space 11 and the second space 12, that is, the partition member 4 and the inner wall of the housing 1 can be filled by the partition portion 72 to ensure the independence of the two spaces, thereby effectively reducing the mutual interference between the first antenna 5 and the second antenna 6, and effectively confining the electromagnetic fields generated by them within the corresponding spaces.

[0047] In some embodiments, the two ends of the separator 4 may extend directly toward the inner wall of the housing 1, and the separator 4 abuts against the inner wall of the housing 1. Therefore, the separator 72 is not required, and the separator 4 can adequately isolate the first space 11 and the second space 12.

[0048] In summary, the microphone provided in this application features a metal housing 1, which provides high structural strength, effectively resisting damage from drops or impacts, enhancing durability, and extending the microphone's lifespan. Furthermore, the metal material gives the microphone a premium feel, making it more suitable for high-end conference environments and other occasions where microphone appearance is critical. Additionally, the microphone in this application includes a first antenna 5 and a second antenna 6. This dual-antenna configuration improves signal transmission efficiency. The first antenna 5 and the second antenna 6 transmit wireless audio signals through a wave-transparent structure. A metal separator 4 is also incorporated inside the microphone to form an electromagnetic barrier between the first antenna 5 and the second antenna 6. The first space 11 and the second space 12 separated by the separator 4 form two relatively independent spaces, effectively isolating the radiation field between the first antenna 5 and the second antenna 6 and reducing signal interference between the two antennas. Therefore, the microphone in this application retains the high structural strength and premium feel of the metal housing 1 while incorporating a dual-antenna structure, significantly improving signal transmission efficiency.
