[0009] Optionally, the support arm has a connecting portion on one side facing the base, and the connecting portion is connected to the base by screws; the support arm also includes a positioning portion on one side facing the base, the positioning portion and the connecting portion are spaced apart, and the base has a positioning groove for accommodating the positioning portion.

[0010] Optionally, the base has a notch that is recessed towards the outer placement surface, and the depth of the notch is the same as the thickness of the support arm; the positioning groove is formed on the inner wall of the notch, and the outer contour of the support arm matches the inner contour of the notch.

[0011] Optionally, the first connecting line and / or the second connecting line are flexible ribbon cables.

[0012] Optionally, the microphone includes two hinges, each hinge having a third wiring channel; one hinge passes through the microphone body and the first support arm, and the other hinge passes through the microphone body and the second support arm; the third wiring channel of one hinge connects the first wiring channel and the interior of the microphone body, and the third wiring channel of the other hinge connects the second wiring channel and the interior of the microphone body.

[0013] Optionally, along the axial direction of the rotating shaft, the third wiring channel passes through one end of the rotating shaft, and the third wiring channel also passes through the periphery of the rotating shaft.

[0014] Optionally, the rotating shaft further includes a connecting section and a rotating section connected to each other; the connecting section is provided with external threads, the connecting section is connected to the first support arm or the second support arm, and the rotating section is rotatably connected to the microphone body; the third wiring channel includes a wire-passing hole provided on the circumference of the rotating shaft, the wire-passing hole being located between the connecting section and the rotating section.

[0015] The microphone of this invention includes a support arm, a microphone body, and a base. The support arm includes a first support arm and a second support arm, the first support arm having a first wiring channel inside, and the second support arm having a second wiring channel inside. The microphone body is movably connected to the first and second support arms, and a PCB board is disposed inside the microphone body. The base is connected to the first and / or second support arms, and has a first connection port and a second connection port.

The first and second wiring channels also limit the movement of the first and second connecting wires, preventing them from being exposed and tangled with external objects. This also makes the microphone's appearance cleaner and reduces the clutter caused by exposed wires. Furthermore, unlike traditional microphones that place the connectors on the microphone body, the first and second connectors in this application are located on the base. This frees up more internal space in the microphone body, providing room for subsequent optimization of the acoustic cavity, or allowing for the inclusion of more sound effect modules within the microphone body, thus enriching its functionality.

[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. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

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

[0029] Reference Figures 1 to 4This application provides a microphone, which includes a support arm 1, a microphone body 2, and a base 3. The support arm 1 includes a first support arm 111 and a second support arm 121. The first support arm 111 has a first wiring channel inside, and the second support arm 121 has a second wiring channel inside. The microphone body 2 is movably connected to the first support arm 111 and the second support arm 121, and a PCB board is provided inside the microphone body 2. The base 3 is connected to the first support arm 111 and / or the second support arm 121, and the base 3 has a first connection port and a second connection port. The first connection port is connected to one end of a first connecting wire 4, and the first connecting wire 4 is connected to the PCB board through the first wiring channel. The second connection port is connected to one end of a second connecting wire 5, and the second connecting wire 5 is connected to the PCB board through the second wiring channel.

[0030] According to the above structure, in the microphone of this application, the first connecting cable 4 and the second connecting cable 5 can be hidden, avoiding the influence of the connecting cables on the rotation of the microphone body 2, and preventing the first connecting cable 4 or the second connecting cable 5 from getting stuck between the microphone body and the support arm 1, thereby reducing wear on the connecting cables. The first and second cable routing channels also limit the movement of the first connecting cable 4 and the second connecting cable 5, preventing them from being exposed and tangled with external objects, and also making the microphone's appearance simpler, reducing the clutter caused by exposed connecting cables. Furthermore, unlike traditional microphones that place the connection port on the microphone body, the first and second connection ports in this application are located on the base 3, thereby freeing up more internal space for the microphone body, providing space for subsequent optimization of the acoustic cavity, or allowing for the installation of more sound effect modules inside the microphone body, enriching the microphone's functionality.

[0031] Understandably, to simplify the overall structure of the microphone, the support arm 1 is usually designed to be relatively small. Consequently, the first and second cable routing channels inside the support arm 1 are also narrow; the width of the first channel is sufficient to accommodate the first connecting cable 4, and the width of the second channel is sufficient to accommodate the second connecting cable 5. Therefore, during microphone installation, threading the connecting cables through these narrow channels is time-consuming and labor-intensive, requiring significant time from the staff.

[0032] Reference Figure 4In some embodiments, the support arm 1 is provided with a groove 13, which is arranged along the extending direction of the first support arm 111 and the second support arm 121. The support arm 1 is also provided with a cover plate 14, which covers the groove 13 to form a first wiring channel and a second wiring channel. Therefore, during installation, it is not necessary to pass the connecting wires through narrow channels. The operator places the first connecting wire 4 along the groove 13, then places the second connecting wire 5 along the groove 13, and then covers it with the cover plate 14. In this way, the first and second wiring channels are formed between the cover plate 14 and the groove 13, allowing the first and second connecting wires 4 and 5 to be hidden within them. The entire installation process is convenient and quick. Furthermore, the groove 13 has a recessed structure on the support arm 1, ensuring that the first and second connecting wires 4 and 5 do not protrude from the surface of the support arm 1 after being inserted.

[0033] Reference Figure 4 In some embodiments, the base 3 is located at the bottom of the support arm 1; the first support arm 111 has a first outlet 111 on the side facing the base 3, and the first outlet 111 communicates with the first wiring channel; the second support arm 121 has a second outlet 121 on the side facing the base 3, and the second outlet 121 communicates with the second wiring channel. Thus, the first outlet 111 and the second outlet 121 are positioned closest to the base 3, allowing the first connecting wire 4 to pass through the first outlet 111 and connect to the first connecting port on the base 3 nearby, preventing the first connecting wire 4 from being exposed. The second outlet 121 is positioned similarly, achieving the same effect.

[0034] In some embodiments, the cover plate 14 is snapped or glued to the support arm 1. Specifically, when the first connecting line 4 and the second connecting line 5 are arranged in the groove 13, the cover plate 14 can cover the groove 13 and be fixed by snapping. The cover plate 14 may have a slot, and the support arm 1 may have a locking block facing the inside of the groove 13. When the cover plate 14 is closed to the groove 13, the locking block engages with the slot to fix it. Alternatively, the cover plate 14 can also be fixed by adhesive.

[0035] Reference Figure 4 and Figure 5 In some embodiments, the support arm 1 has a connecting portion 15 on the side facing the base 3, and the connecting portion 15 is connected to the base 3 by screws; the support arm 1 also includes a positioning portion 16 on the side facing the base 3, the positioning portion 16 and the connecting portion 15 being spaced apart, and the base 3 having a positioning groove 32 for accommodating the positioning portion 16. It is understood that, to prevent the first connecting line 4 from twisting or tangling after entering the base 3 from the first connecting channel, the support arm 1 and the base 3 need to be maintained at a preset position to prevent relative rotation between the support arm 1 and the base 3, which could pull on the first connecting line 4 and the second connecting line 5. Specifically, refer to... Figure 4The connecting part 15 protrudes from the support arm 1, and the base 3 is provided with a through hole 33 to accommodate the connecting part 15. During installation, the operator aligns the connecting part 15 of the support arm 1 with the through hole 33 and the positioning part 16 with the positioning groove 32, then inserts the connecting part 15 into the through hole 33 and the positioning part 16 into the positioning groove 32. Finally, the screw is screwed into the connecting part 15 through the through hole 33. Thus, the positioning part 16 provides a second positioning point for the connection between the support arm 1 and the base 3. When both the positioning part 16 and the connecting part 15 are in place, it indicates that the support arm 1 and the base 3 are in the preset position. The positioning part 16 is located within the positioning groove 32, preventing relative rotation between the support arm 1 and the base 3 during screwing.

[0036] Reference Figure 4 In some embodiments, the base 3 has a notch 31, which is recessed towards the outer placement surface, and the depth of the notch 31 is the same as the thickness of the support arm 1. A positioning groove 32 is formed on the inner wall of the notch 31, and the outer contour of the support arm 1 matches the inner contour of the notch 31. Specifically, when the support arm 1 is connected to the base 3, a portion of the support arm 1 is located at the notch 31, and the top of the base 3 is flush with the portion of the support arm 1 located at the notch 31. Therefore, the base 3 does not protrude from the support arm 1 and does not obstruct the rotation of the microphone body 2.

[0037] In some embodiments, the first connecting line 4 and / or the second connecting line 5 are flexible ribbon cables. As a result, the flexible ribbon cable is thin and light, and can fit tightly against the inner wall of the groove 13. This also allows the support arm 1, which houses the first connecting line 4 and the second connecting line 5, to be made thinner and lighter, making the overall structure of the microphone smaller and more compact.

[0038] Reference Figures 6 to 9 In some embodiments, the microphone includes two pivots 6, each pivot 6 having a third wiring channel 61. One pivot 6 passes through the microphone body and the first support arm 111, while the other pivot 6 passes through the microphone body and the second support arm 121. The third wiring channel 61 of one pivot 6 connects the first wiring channel and the interior of the microphone body, while the third wiring channel 61 of the other pivot 6 connects the second wiring channel and the interior of the microphone body. Thus, the pivot 6 not only supports the rotation of the microphone body but also provides wiring channels for the first connecting cable 4 and the second connecting cable 5, enabling the compact pivot 6 to have dual functions and making the overall structure of the microphone more streamlined and compact. Furthermore, the third wiring channel 61 can conceal the first connecting cable 4 and the second connecting cable 5, preventing exposure and making the microphone wiring clearer and more orderly. The third wiring channel 61 also protects the first connecting cable 4 and the second connecting cable 5, thereby reducing the probability of cable damage.

[0039] In some embodiments, along the axial direction of the rotating shaft 6, a third wiring channel 61 extends through one end of the rotating shaft 6, and the third wiring channel 61 also extends through the periphery of the rotating shaft 6. Specifically, the end of the rotating shaft 6 with the cable outlet is located inside the microphone body, and the periphery of the rotating shaft 6 with the cable outlet faces the support arm 1. In this way, the first connecting cable 4 and the second connecting cable 5 can smoothly enter the first wiring channel and the second wiring channel through the inside of the microphone body.

[0040] In some embodiments, the rotating shaft 6 further includes a connecting section 62 and a rotating section 63 connected to each other; the connecting section 62 is provided with an external thread and is connected to the first support arm 111 or the second support arm 121, and the rotating section 63 is rotatably connected to the microphone body. Thus, the rotating shaft 6 is partly used for the rotation of the microphone body and partly for connection. Specifically, the rotating section 63 passes through the microphone body, and the portion of the rotating section 63 located inside the microphone body is also provided with a clamping head 65. The clamping head 65 protrudes circumferentially from the rotating section 63 and can abut against the interior of the microphone body, preventing the rotating shaft 6 from disengaging from the microphone body. The microphone is also equipped with a knob 7, the internal thread of which is connected to the external thread of the connecting section 62. The support arm 1 is connected to the connecting section 62. When the microphone body rotates around the rotating shaft 6 to adjust the angle, after confirming the angle, the knob 7 is locked to make the support arm 1 and the microphone body abut against each other to fix the angle.

[0041] In some embodiments, the third wiring channel 61 includes a wire passage hole 64 located on the periphery of the rotating shaft 6, between the connecting section 62 and the rotating section 63. Thus, the wire passage hole 64 minimizes the impact on the rotation of the microphone body and the connection of the support arm 1. In this embodiment, the wire passage hole 64 is the wire outlet located on the periphery of the rotating shaft 6 as defined above.

[0042] Reference Figure 9 In some embodiments, the microphone further includes a positioning piece 8. The positioning piece 8 is connected to the side of the support arm 1 away from the microphone body and is elastic; the knob 7 is connected to the rotating shaft 6 and is located on the side of the positioning piece 8 away from the support arm 1; wherein, the microphone includes a locked state and an adjusted state. In the locked state, the knob 7 presses the positioning piece 8 against the support arm 1, and in the adjusted state, there is a gap between the positioning piece 8 and the support arm 1.

[0043] Specifically, when knob 7 is rotated to disengage from shaft 6, positioning plate 8 still retains the microphone body and support arm 1 on shaft 6, preventing the support arm 1 from separating from the microphone body and providing safety for the microphone. In the locked state, knob 7, positioning plate 8, support arm 1, and microphone body are sequentially pressed together, thereby locking the angle of the microphone body. In the adjustment state, knob 7 is rotated away from positioning plate 8, creating a gap between positioning plate 8 and support arm 1. This releases the pressure between positioning plate 8, support arm 1, and microphone body, allowing the microphone body to rotate freely. Once the microphone body rotates to the desired angle, knob 7 is locked, thus returning to the locked state.

[0044] In some embodiments, the positioning piece 8 can be an elastic plastic or rubber pad. The positioning piece 8 can be connected to the support arm 1 by screws, and the screws do not completely press the positioning piece 8 against the outer wall of the support arm 1. In the initial state, there is a gap between the positioning piece 8 and the support arm 1. When locking is required, the knob 7 is rotated, and the knob 7 presses against the positioning piece 8. Then, the knob 7, the positioning piece 8, the support arm 1, and the microphone body 2 can be pressed against in sequence, and the microphone is in a locked state. When the angle needs to be adjusted, the knob 7 is gradually moved away from the positioning piece 8. Then, there is a gap between the positioning piece 8 and the support arm 1, and the support arm 1 will not press against the microphone body. The microphone body can rotate to adjust the angle.

[0045] In summary, in the microphone of this application, the first connecting cable 4 and the second connecting cable 5 can be concealed, avoiding any impact on the rotation of the microphone body 2. This also prevents either the first connecting cable 4 or the second connecting cable 5 from getting stuck between the microphone body and the support arm 1, thus reducing wear on the connecting cables. The first and second cable routing channels also limit the movement of the first connecting cable 4 and the second connecting cable 5, preventing them from being exposed and tangled with external objects. Furthermore, this makes the microphone's appearance cleaner and reduces the clutter caused by exposed cables. In addition, unlike traditional microphones that place the connection ports on the microphone body, the first and second connection ports in this application are located on the base 3, freeing up more internal space for the microphone body. This provides space for subsequent optimization of the acoustic cavity, or allows for the installation of more sound effect modules inside the microphone body, enriching the microphone's functionality.
