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

[0032] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0033] Reference Figures 1 to 8The present invention provides a microphone, which is provided with a first audio interface 1 and a second audio interface 2, and the first audio interface 1 and the second audio interface 2 are used to connect different audio lines; an antenna 3 is also provided inside the microphone, and the antenna 3 is used to transmit wireless audio signals; the microphone also includes a receiver, and the receiver is used to connect to an external device and receive the wireless audio signal sent by the antenna 3.

[0034] According to the above structure, the microphone in this application is provided with a first audio interface 1, a second audio interface 2 and a built-in antenna 3, and the user can select according to the interface type of the connected device. Among them, the first audio interface 1 and the second audio interface 2 can be connected to different audio cables. For example, the first audio interface 1 can be a USB interface, and the user can connect to a computer and other devices. The second audio interface 2 can be a Canon interface, and the user can connect to more professional audio devices such as a mixing console. In addition, the setting of the antenna 3 can also make the microphone have a wireless function, and will not be constrained by the connecting cable when using the microphone, thereby improving the convenience of use. In this way, the microphone designed in this application can flexibly adapt to various usage environments and meet the diverse connection needs of users.

[0035] Reference Figure 2 In some embodiments, the first audio interface 1 is a USB interface, and the second audio interface 2 is a XLR interface. In other embodiments, the first audio interface 1 may also be a XLR interface, and the second audio interface 2 may also be a USB interface. Thus, the USB interface enables the microphone to be connected to digital devices such as computers and tablets, meeting the needs of modern digital audio applications. The XLR interface configuration ensures that the microphone can be connected to more professional audio equipment such as mixing consoles and amplifiers, providing high-quality audio effects for professional recording studios, performances, and broadcasting scenarios.

[0036] In some embodiments, the microphone includes: a shell 4; a support frame 5, the support frame 5 is connected to the inside of the shell 4; a circuit board is installed on the support frame 5, the first audio interface 1, the second audio interface 2 and the antenna 3 are all connected to the circuit board, and the first audio interface 1 and the second audio interface 2 pass through the shell 4. Thus, the provision of a circuit board can help reduce the overall weight of the microphone, making the microphone as a whole lighter and more suitable for mobile use. Specifically, the shell 4 includes a bottom side 43 for facing the external support surface, the first audio interface 1 and the second audio interface 2 can pass through the bottom side 43, and the antenna can also face the bottom side 43, wherein the bottom side 43 can have a window, which provides a channel for the transmission of wireless signals, ensuring the efficiency and stability of signal transmission.

[0037] Reference Figure 4 and Figure 5In some embodiments, a microphone includes: a housing 4; a support frame 5 connected to the interior of the housing 4; a first circuit board 6 mounted on the support frame 5, with a first audio interface 1 connected to the first circuit board 6 and extending through the housing 4; and a second circuit board 7 mounted on the support frame 5, with a second audio interface 2 connected to the second circuit board 7 and extending through the housing 4. A microphone contains numerous electronic components, and the circuit boards are typically quite large. Unlike the aforementioned embodiment, which only includes a single circuit board, the provision of the first circuit board 6 and the second circuit board 7 in this embodiment can be understood as splitting a larger circuit board into two smaller ones. This allows for more flexible placement of the two circuit boards within the microphone, fully utilizing the internal space, resulting in a more compact internal structure and a more compact overall microphone. Furthermore, the provision of the first circuit board 6 and the second circuit board 7 allows for the electronic components to be distributed across different circuit boards. If the first audio interface 1 or the second audio interface 2 malfunctions, maintenance personnel can independently troubleshoot each circuit board, improving repair efficiency.

[0038] Reference Figure 2 and Figure 3 In some embodiments, the housing 4 includes a bottom side 43 facing the external support surface; the first circuit board 6 and the second circuit board 7 extend toward the bottom side 43, and the first audio interface 1 and the second audio interface 2 extend through the bottom side 43. Thus, when in use, the microphone can be placed on a desktop with the bottom side 43 facing downward, and the first audio interface 1 and the second audio interface 2 also facing downward. During daily use, the downward-facing first audio interface 1 and the second audio interface 2 can also reduce dust accumulation. In addition, visually, the first audio interface 1 and the second audio interface 2 located on the bottom side 43 can also be more concealed, making the appearance of the microphone more concise and beautiful.

[0039] In some embodiments, antenna 3 is connected to first circuit board 6 and is located near bottom side 43. In other embodiments, antenna 3 is connected to second circuit board 7 and is located near bottom side 43. Specifically, because bottom side 43 of housing 4 faces an external support surface such as a desktop during daily use and is not easily observable, the design does not require particular consideration of the appearance of bottom side 43. In this embodiment, since antenna 3 is located near bottom side 43, a window can be provided on bottom side 43. This window provides a channel for wireless signal transmission, ensuring efficient and stable signal transmission.

[0040] Reference Figure 4 and Figure 5In some embodiments, the microphone includes: a housing 4; a support frame 5, the support frame 5 being connected to the inside of the housing 4; a first circuit board 6, mounted on the support frame 5, the first audio interface 1 being connected to the first circuit board 6, and the first audio interface 1 passing through the housing 4; a second circuit board 7, mounted on the support frame 5, the second audio interface 2 being connected to the second circuit board 7, and the second audio interface 2 passing through the housing 4; a third circuit board 8, mounted on the support frame 5, and the antenna 3 being connected to the third circuit board 8. Thus, the first audio interface 1, the second audio interface 2, and the antenna 3 can be connected to different circuit boards respectively. If one of the audio interfaces or the antenna 3 fails, the staff can check a certain circuit board separately during maintenance, thereby improving maintenance efficiency. Among them, the first circuit board 6, the second circuit board 7, and the third circuit board 8 can be electrically connected via connecting wires.

[0041] Reference Figures 3 to 5 In some embodiments, the housing 4 includes a bottom side 43 facing the external support surface; the first circuit board 6 and the second circuit board 7 extend toward the bottom side 43, with the first audio interface 1 and the second audio interface 2 extending through the bottom side 43; and the antenna 3 is located on the side of the third circuit board 8 facing downward toward the bottom side 43. Thus, during use, the microphone can be placed on a tabletop with the bottom side 43 facing downward, with the first audio interface 1 and the second audio interface 2 also facing downward. This reduces dust accumulation on the first audio interface 1 or the second audio interface 2 during daily use. Furthermore, the first audio interface 1 and the second audio interface 2 located on the bottom side 43 are more visually concealed, giving the microphone a simpler and more aesthetically pleasing appearance. Furthermore, the antenna 3 is located on the side of the third circuit board 8 facing downward toward the bottom side 43. Specifically, since the bottom side 43 of the housing 4 is not easily visible during daily use, the appearance of the bottom side 43 does not need to be a major consideration. Positioning the antenna 3 near the bottom side 43 allows for a window to facilitate wireless signal transmission, ensuring efficient and stable signal transmission.

[0042] In some embodiments, the first circuit board 6 and the second circuit board 7 are respectively located on opposite sides of the support frame 5; the first circuit board 6 and the second circuit board 7 are respectively perpendicular to the surface of the third circuit board 8. The internal electronic components of the microphone can be distributed on the side of the first circuit board 6 facing away from the support frame 5, or on the side of the second circuit board 7 facing away from the support frame 5, or on the side of the third circuit board 8 facing downward from the first circuit board 6 and the second circuit board 7. Thus, the layout of the first circuit board 6, the second circuit board 7, and the third circuit board 8 fully utilizes the space inside the housing 4, and can more reasonably arrange the electronic components in the horizontal and vertical directions, making the layout of the electronic components inside the housing 4 three-dimensional and orderly. This not only makes the connection between the circuit boards tighter, but also reduces the waste of internal space, thereby improving the compactness and stability of the entire housing structure. In addition, through a reasonable layout, the heat dissipation efficiency can be effectively improved, ensuring the stability and reliability of the first circuit board 6, the second circuit board 7, and the third circuit board 8 under long-term operation.

[0043] In some embodiments, the microphone further includes a battery 9 and an encoder 10, and the first circuit board 6 and the second circuit board 7 are located on opposite sides of the support frame 5. In some examples, the first circuit board 6 is connected to the encoder 10, and the second circuit board 7 is connected to the battery 9; in other examples, the first circuit board 6 is connected to the battery 9, and the second circuit board 7 is connected to the encoder 10. Specifically, since the battery 9 and the encoder 10 are large in size and heavy in weight, arranging the battery 9 and the encoder 10 on both sides of the support frame 5 can effectively achieve a balanced weight distribution, reducing the risk of the microphone tilting or tipping over due to uneven weight during use, and making the microphone more stable.

[0044] Reference Figure 1 and Figure 9 In some embodiments, the housing 4 includes an outer shell 41 and a cover 42 that are interconnected. The cover 42 covers the outer shell 41, with its outer surface facing the external support surface. The outer shell 41 is made of metal. As a result, the metal outer shell 41 has greater strength, effectively resisting external shock and vibration, and protecting the electronic components within the microphone from damage. Furthermore, the texture and glossiness of the metal make the microphone more visually appealing, meeting the aesthetic requirements of professional audio equipment.

[0045] In some examples, the housing 41 may be made of aluminum alloy, stainless steel, or the like.

[0046] In some embodiments, the cover 42 may be made of plastic. Specifically, the metal housing 41 may reflect electromagnetic waves to a certain extent, causing the microphone signal to be weakened when using the wireless function. In this embodiment, the plastic cover 42 does not affect the transmission of wireless signals. In particular, when the antenna 3 is located near the cover 42, even if the housing 41 is made of metal, it will not significantly weaken the wireless signal.

[0047] In some embodiments, the shell 4 includes a protective structure 44 and a wave-transparent structure 45; the antenna 3 is disposed in the shell 4, and the antenna 3 is used to transmit wireless audio signals; wherein the protective structure 44 is made of metal, and the wave-transparent structure 45 is used to provide a channel for the antenna 3 to transmit wireless audio signals. As a result, the microphone can significantly enhance the strength and durability of the microphone through the metal protective structure 44, effectively resist damage caused by falling or collision, extend the service life of the microphone, and have higher safety and reliability. In addition, in order to prevent the metal shell 4 from affecting the transmission of wireless signals, the microphone in the present application is also provided with a wave-transparent structure 45. The wave-transparent structure 45 can provide a smooth channel for the transmission of wireless audio signals, reduce signal loss and interference, and thus improve the transmission efficiency and stability of the signal. In this way, the microphone provided by the present application can have a long service life, and can also meet the needs of high-end conference environments and other occasions with high requirements for the appearance of the microphone, meeting the user's demand for high-quality audio equipment.

[0048] Reference Figure 9 and Figure 10 In some embodiments, housing 4 includes an outer shell 41, which serves as a protective structure 44. Housing 41 defines a first window communicating with the exterior, forming a wave-transmitting structure 45. Thus, in this embodiment, wave-transmitting structure 45 is a hollow structure, ensuring smooth transmission of wireless audio signals. Specifically, the first window can be located on the side of housing 41, and the outline of the first window can be designed to resemble a unique shape based on the user's individual needs, thereby enhancing microphone recognition and cleverly integrating functionality and aesthetics into the design of housing 4.

[0049] Reference Figure 10 In some embodiments, the wave-transmitting structure 45 further includes a first wave-transmitting member 451, which is embedded in the first window to seal the first window. Thus, the provision of the first wave-transmitting member 451 can seal the first window, preventing dust and moisture from entering the microphone interior. This ensures that the microphone maintains good working condition even in complex environments, extending the service life of the device while also reducing maintenance frequency and costs.

[0050] In some embodiments, the first wave-transparent member 451 is a wave-transparent material. Thus, the first wave-transparent member 451 uses a wave-transparent material to ensure smooth transmission of wireless audio signals. In some examples, the wave-transparent material can be made of plastic, such as ABS plastic, polycarbonate, etc., which is light in weight and low in cost. In some examples, the wave-transparent material can also be made of ceramic material, such as alumina ceramic, which can have high strength and heat resistance while having good wave-transparent performance. In other examples, the wave-transparent material can also be made of silicone or rubber, which can also have a good sealing effect to better seal the first window.

[0051] In some embodiments, the shell 4 includes a protective layer, which covers the surface of the wave-transparent component; in other embodiments, the shell 4 includes a protective layer, which covers the surface of the protective layer. Thus, the protective layer is provided on the surface of the wave-transparent component and / or the surface of the protective layer, which significantly improves the wear resistance and overall aesthetics of the shell 4. Specifically, the protective layer can not only effectively protect the shell 4 and make the surface of the shell 4 smoother, but also reduce scratches and wear caused by use and extend the service life of the equipment. In addition, the provision of the protective layer can also visually form a unified overall sense, enhancing the aesthetics and texture of the product. In some examples, the protective layer can also be a metal plating. Since the metal plating is relatively thin, it will not have a significant impact on the transmission of wireless signals.

[0052] Reference Figure 11 In some embodiments, the housing 4 includes an outer shell 41 and a cover 42 that are interconnected. The cover 42 is used to cover the outer shell 41, with the outer side of the cover 42 facing the external support surface. The outer shell 41 is a protective structure 44, and the cover 42 is provided with a wave-transmitting structure 45. Specifically, in some examples, the cover 42 can be entirely made of plastic. The plastic cover 42 does not affect the transmission of wireless signals. In particular, when the antenna 3 is located near the cover 42, even if the outer shell 41 is a metal shell 41, it will not significantly weaken the wireless signal.

[0053] In some embodiments, the cover plate 42 is provided with a second window communicating with the outside, and the second window forms a wave-transmitting structure 45. Thus, in this embodiment, the cover plate 42 can also be made of metal, and the second window is a hollow structure, which can form a channel for wireless signal transmission, ensuring smooth transmission of wireless audio signals.

[0054] Reference Figure 11 In some embodiments, the wave-transmitting structure 45 further includes a second wave-transmitting member 452, which is embedded in the second window to seal the second window. Specifically, the second wave-transmitting member 452 can also be made of a wave-transmitting material such as ABS plastic, alumina ceramic, silicone, etc.

[0055] Reference Figure 12In some embodiments, the housing 4 is cylindrical, and the wave-transmitting structure 45 is disposed in a surrounding manner. In some examples, the surrounding wave-transmitting structure 45 may be a plastic ring. Specifically, the housing 4 may be formed by connecting a metal ring and a plastic ring. Because the plastic ring forms a surrounding structure, the surrounding sides of the plastic ring can form a channel for transmitting wireless signals, thereby improving signal transmission efficiency and stability.

[0056] Reference Figure 1 and Figure 2 Specifically, the microphone further includes a base 11, which can be supported on an external support surface such as a desktop, and the base 11 is connected to the housing 4. It is understandable that the microphone further includes a receiver for receiving wireless signals, and the receiver can be plugged into a device such as a computer, tablet or mobile phone. It should be noted that in addition to the aforementioned structure, the microphone also includes structures for realizing other basic functions. The structures for realizing other basic functions can refer to the relevant technologies in the field and will not be described in detail here.

[0057] In summary, the microphone in this application is provided with a first audio interface 1, a second audio interface 2 and a built-in antenna 3, and the user can select according to the interface type of the connected device. Among them, the first audio interface 1 and the second audio interface 2 can be connected to different audio cables. For example, the first audio interface 1 can be a USB interface, and the user can connect to a computer and other devices. The second audio interface 2 can be a Canon interface, and the user can connect to more professional audio devices such as a mixing console. In addition, the setting of the antenna 3 can also make the microphone have a wireless function, and will not be constrained by the connecting cable when using the microphone, thereby improving the convenience of use. In this way, the microphone designed in this application can flexibly adapt to various usage environments and meet the diverse connection needs of users.
