[0002] With the development of technology, microphones are widely used in various occasions, and people's demand for the use of microphones has gradually become diversified. Existing microphones are mainly divided into two categories: fixed type and wearable type. The gooseneck hose of the fixed microphone is relatively long, and the direction can be adjusted flexibly, which is suitable for professional recording and speech occasions. The gooseneck hose of the wearable microphone is relatively short, which is more convenient to carry and use, and is suitable for daily meetings, interviews and other occasions that require convenient carrying. However, both existing microphones have their limitations: the fixed microphone is not as portable as the wearable one, while the wearable microphone is inferior to the fixed one in terms of flexibility and functions. Therefore, designing a microphone that can be flexibly switched between the fixed type and the wearable type according to the usage requirements has become a problem to be solved in the current technical field.

Detailed implementation manner
[0016] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0017] As Figures 1 - 11 shown, a wireless Bluetooth microphone of a head-mounted type proposed in an embodiment of the present invention includes: The main bracket 1 is arc-shaped and has two free ends. The two free ends of the main bracket 1 are slidably sleeved with an arc-shaped sleeve plate 2. A regulating sleeve plate 4 is rotatably installed on the outer arc side of one of the arc-shaped sleeve plates 2. A limiting arc groove is provided on the outer arc surface of the main bracket 1, and a limiting plate 1506 located in the limiting arc groove is installed on the arc-shaped sleeve plate 2 to prevent the arc-shaped sleeve plate 2 from being pulled out of the main bracket 1. Moreover, the arc-shaped sleeve plate 2 and the main bracket 1 are in close sliding fit. In this way, after the user pulls the arc-shaped sleeve plate 2, the arc-shaped sleeve plate 2 is prevented from moving by itself after the user wears it. This part of the structure is similar to the earphone adjusting part of the existing head-mounted earphone. The free end of the regulating sleeve plate 4 is slidably inserted with an arc-shaped insertion plate 5. An installation seat 6 is installed at the free end of the arc-shaped insertion plate 5. An arc-shaped groove 7 is provided on the installation seat 6. The regulating sleeve plate 4, the arc-shaped insertion plate 5 and the main bracket 1 can maintain concentricity. When the regulating sleeve plate 4 rotates to be concentric with the main bracket 1, the arc-shaped groove 7 is inserted onto the main bracket 1. Specifically, the upper and lower surfaces of the position on the middle part of the main bracket 1 where the arc-shaped groove 7 is sleeved are both arc-shaped. When the rotation axis of the regulating sleeve plate 4 is located at the center of the main bracket 1, rotating the regulating sleeve plate 4 at this time can make the arc-shaped groove 7 be sleeved at the middle position of the main bracket 1. Because the upper and lower surfaces of the arc-shaped groove 7 are arc-shaped surfaces, when the regulating sleeve plate 4 moves, the arc-shaped insertion plate 5 will be limited by the arc-shaped groove 7, so that the regulating sleeve plate 4 and the corresponding arc-shaped sleeve plate 2 will move together, without affecting the adjustment of the arc-shaped sleeve plate 2; An installation box 8 is detachably installed on the installation seat 6. A gooseneck hose 9 is installed on the outer side of the installation box 8. A microphone head 10 is installed at the free end of the gooseneck hose 9, thus forming a Bluetooth microphone. The microphone is Bluetooth-connected to an amplifier; Among them, the outer arc side of the other arc-shaped sleeve plate 2 has a connecting portion 11, and the installation seat 6 is detachably installed on the connecting portion 11; A capacitor box 12 is installed on one of the arc-shaped sleeve plates 2. A USB interface is provided on one side of the capacitor box 12. A data cable 13 is connected between the free end of the capacitor box 12 and the installation box 8, such as Figure 2 In the head-mounted state, when it is necessary to change the head-mounted state to, for example, Figure 1 In the fixed state, first detach the installation box 8 from the connecting portion 11, and then install the installation box 8 on the installation seat 6. At this time, rotate the regulating sleeve plate 4 so that the regulating sleeve plate 4 rotates around the center of the main bracket 1, thereby indirectly driving the arc-shaped insertion plate 5 to move, so that the installation seat 6 is located at the highest position (the angle of the regulating sleeve plate 4 can be rotated according to actual use), thus making up for the problem of the too short length of the gooseneck hose 9. Then place the main bracket 1 flat on the desktop (such as Figure 1At this time, the bottom of the arc-shaped sleeve plate 2 will be in contact with the desktop. The two arc-shaped sleeve plates 2 are arc-shaped and have a good supporting effect. Moreover, the arc-shaped sleeve plate 2 can be adjusted as needed to change the occupied area. The audio cable of the indoor loudspeaker can be externally connected at the USB interface, so as to meet the indoor sound amplification effect, and thus the state of the Bluetooth microphone can be changed according to the user's usage scenario.
[0018] As Figure 2 and Figure 11 shown, in some embodiments, a connecting plate 14 away from the center of the main bracket 1 is constructed in the middle of the outer side of the main bracket 1. A supporting sub-bracket 3 is rotatably installed on the connecting plate 14, and a limiting member 15 for limiting the rotation of the supporting sub-bracket 3 is installed on the connecting plate 14. That is to say, as Figure 1 shown, the supporting sub-bracket 3 is rotated to 180 degrees, and then the supporting reset is limited by the limiting member 15. At this time, the end face of the supporting sub-bracket 3 is flush with the side of the arc-shaped sleeve plate 2 in contact with the desktop, so as to increase the contact area and improve the overall stability.
[0019] As Figure 4 and Figure 11 shown, in some embodiments, the supporting sub-bracket 3 includes a rotating rod 301 rotatably installed on the connecting plate 14. Both ends of the rotating rod 301 pass through the connecting plate 14 and are constructed with arc-shaped support plates 302. The arc-shaped support plates 302 are concentric with the main bracket 1. When the free end of the arc-shaped support plate 302 rotates to a position away from the main bracket 1, one side in the length direction of the arc-shaped support plate 302 is flush with one side of the arc-shaped sleeve plate 2. The side of the arc-shaped sleeve plate 2 flush with the arc-shaped support plate 302 is the placement surface, which refers to the side in contact with the desktop or other carriers. When the supporting sub-bracket 3 rotates and resets again, at this time, the whole supporting sub-bracket 3 is concentric with the main bracket 1 and is located directly above the main bracket 1, which not only reduces the occupied area and does not affect the user's wearing, but also the arc-shaped design of the arc-shaped support plate 302 can increase the contact area with the desktop and improve the stability.
[0020] As Figure 11As shown, in some embodiments, the connecting plate 14 is internally constructed with an installation cavity 1501, and the limiting member 15 includes two baffles 1502 installed in the installation cavity 1501, the rotating rod 301 is located between the two baffles 1502, one side of the baffle 1502 is a limiting surface 1503, and the outer peripheral side of the rotating rod 301 is constructed with a convex plate 1504 for contacting the limiting surface 1503, and the outer peripheral side of the rotating rod 301 is provided with two limiting grooves 1505, and a limiting plate 1506 for being inserted into the limiting groove 1505 is slidably installed on the connecting plate 14. That is to say, when it is in a head-mounted state, the limiting plate 1506 is inserted into one of the limiting grooves 1505, which can effectively prevent the arc-shaped support plate 302 from rotating accidentally when worn. When the arc support plate 302 is rotated and unfolded, it is only necessary to move the limit plate 1506 so that the limit plate 1506 is disengaged from the limit groove 1505, and then rotate the arc support plate 302 so that the two arc support plates 302 can contact the desktop. At this time, the convex plate 1504 contacts one of the baffles 1502, and the baffle 1502 plays a limiting role. Then the limit plate 1506 is moved so that the limit plate 1506 is inserted into another limit groove 1505, thereby completing the limiting of the angle of the arc support plate 302. By inserting the limit plate 1506 into different limit grooves 1505, not only the unfolded arc support plate 302 can be limited, but also the arc support plate 302 in the head-mounted state can be limited, which is more convenient to use.
[0021] like Figure 4 and Figure 11 As shown, in some embodiments, the rotating rod 301 is connected to the rotating rod 301 by a torsion spring ( Figure 121506, one end of the torsion spring is connected to the inner side of the connecting plate 14, and the other end of the torsion spring is connected to the rotating rod 301. The torsion spring is sleeved on the rotating rod 301. A clearance groove 16 communicating with the installation cavity 1501 is provided on one side of the connecting plate 14. A driving plate 17 is horizontally elastically slidably installed in the clearance groove 16. Specifically, a resisting spring is installed between the driving plate 17 and the clearance groove 16. A tooth groove 18 is provided on the opposite side of the driving plate 17 and the limiting plate 1506. A tooth groove 18 located between the driving plate 17 and the limiting plate 1506 is rotatably installed on the clearance groove 16. The gear 19 between the limit plates 1506 is meshed with the two tooth grooves 18. The end of the driving plate 17 away from the rotating rod 301 is configured with a forcing block 20. The end of the forcing block 20 away from the rotating rod 301 is symmetrically configured with two forcing inclined surfaces 21. The mounting seat 6 is configured with a convex rod 22 located in the yielding groove 16. The outer side of the convex rod 22 is configured with a forcing plate 23 for contacting the forcing inclined surface 21. When the device is rotated from the head-mounted state to the fixed state, during the process of rotating the adjusting sleeve plate 4, as the adjusting sleeve plate 4 rotates, the mounting seat 6 will also When the mounting seat 6 rotates, it will drive the convex rod 22 connected thereto to move, thereby driving the forcing plate 23 to move. When the forcing plate 23 moves, the forcing plate 23 will contact the forcing inclined surface 21 of the forcing block 20, thereby forcing the forcing block 20 to move. When the forcing block 20 moves, it will indirectly drive the driving plate 17 to move. When the driving plate 17 moves, it will drive the gear 19 to rotate through the tooth groove 18. As the gear 19 rotates, it will drive the limiting plate 1506 to move, so that the limiting plate 1506 moves in the direction away from the limiting groove 1505. Then, the torsion spring will cause the rotating rod 301 to rotate quickly, thereby causing the arc support plate 302 to rotate automatically. When the head-mounted state is converted into a fixed state, the arc support plate 302 will rotate automatically, thereby simplifying the process of changing the state and improving the stability of the support, making it more convenient to use. After the arc support plate 302 completes the automatic rotation, the driving plate 17 will be quickly reset through the resistance spring sheet, thereby causing the limit plate 1506 to be automatically inserted into the corresponding limit groove 1505, thereby automatically fixing the arc support plate 302.
[0022] like Figure 1 , Figure 10 and Figure 11As shown, in some embodiments, the connecting portion 11 includes a positioning plate formed on the outer arc surface of the arc-shaped sleeve plate 2. The positioning plate is L-shaped. A first metal sheet 24 is installed at the wall thickness of the arc-shaped sleeve plate 2 where the positioning plate is installed, and a second metal sheet 25 is installed at the wall thickness of the mounting seat 6. A magnetic plate 26 for continuously adsorbing to the first metal sheet 24 and the second metal sheet 25 is installed in the mounting box 8. That is to say, when the mounting box 8 is placed on the inner right-angle surface of the L-shaped positioning plate, at this time, the magnetic plate 26 just adsorbs on the first metal sheet 24 to complete the quick installation. Similarly, when the mounting box 8 is placed on the mounting seat 6, the magnetic plate 26 just adsorbs on the second metal sheet 25 to complete the quick installation. Through the design of the magnetic plate 26 and the metal sheet, the quick installation of the mounting box 8 can be realized, and the state change is more rapid.
[0023] As Figure 9 and Figure 10 shown, in some embodiments, a knob 27 is rotatably installed on the outside of the mounting box 8. One end of the knob 27 is located inside the mounting box 8 and is formed with a convex disk 28. A column rod 29 is eccentrically formed on the outside of the convex disk 28. A sliding frame 30 is slidably installed in the mounting box 8. The column rod 29 is tangent to the inside of the sliding frame 30. One side of the sliding frame 30 is formed with a mounting plate 31, and the magnetic plate 26 is installed on the mounting plate 31. In order to further facilitate the detachment of the magnetic sheet from the metal sheet, when the knob 27 is rotated, the rotation of the knob 27 can drive the rotation of the convex disk 28, and then drive the rotation of the column rod 29. As the column rod 29 rotates, because the column rod 29 is located inside the sliding frame 30, when the knob 27 is rotated, the column rod 29 will move inside the sliding frame 30, thereby forcing the sliding frame 30 to move vertically. The movement of the sliding frame 30 will drive the movement of the magnetic plate 26. The movable design of the magnetic plate 26 can improve the magnetism of the magnetic plate 26 to improve the adsorption effect, and the design of the knob 27 facilitates the detachment of the magnetic plate 26 from the corresponding metal sheet.
[0024] As Figures 6 - 7 shown, in some embodiments, an elastic telescopic rod 32 is rotatably installed in the mounting box 8. The rotation axis of the elastic telescopic rod 32 passes through the center of the convex disk 28. The movable end of the elastic telescopic rod 32 is hinged to one side of the sliding frame 30. When the knob 27 is rotated, the rotation of the convex disk 28 will drive the elastic telescopic rod 32 to retract. When the central axis of the elastic telescopic rod 32 passes through the center of the convex disk 28, at this time, the elastic telescopic rod 32 will reset due to its own elastic deformation, so that the movable end of the elastic telescopic rod 32 quickly extends, thereby enabling the sliding frame 30 to move quickly, and further enabling the magnetic plate 26 to quickly approach the corresponding metal sheet, making it more convenient for the user to rotate the knob 27.
[0025] As Figure 8As shown, in some embodiments, an external thread sleeve 33 is constructed on the outer side of the adjusting sleeve plate 4. A rotating sleeve 34 is sleeved on the external thread sleeve 33 by threads. A rod body 35 is installed at one end of the rotating sleeve 34. A plugging cylinder 36 is slidably sleeved on the rod body 35. A connecting spring 37 is installed between the rod body 35 and the plugging cylinder 36. A positioning hole 38 for the plugging cylinder 36 to be inserted is formed on one side of the arc-shaped plug plate 5. When the plugging cylinder 36 is inserted into the positioning hole 38, the rotation axis of the adjusting sleeve plate 4 passes through the center of the main bracket 1. Specifically, when the plugging cylinder 36 is inserted into the positioning hole 38, the rotation axis of the adjusting sleeve plate 4 at this time will pass through the center of the main bracket 1, playing a positioning role. When the state of the headset needs to be changed to a fixed state, at this time, the rotating sleeve 34 is screwed. When the rotating sleeve 34 rotates, it will cause the plugging cylinder 36 to move, so that the plugging cylinder 36 abuts against the arc-shaped plug plate 5. When the arc-shaped sleeve plate 2 is moved, the movement of the arc-shaped sleeve plate 2 will drive the arc-shaped plug plate 5 to move. When the positioning hole 38 of the arc-shaped plug plate 5 moves to be coaxial with the plugging cylinder 36, the plugging cylinder 36 will be inserted into the positioning hole 38 through the connecting spring 37, thereby completing the limit of the arc-shaped plug plate 5. At this time, when the adjusting sleeve plate 4 is rotated, it can ensure that the arc-shaped groove 7 can be separated from the main bracket 1, and it can ensure that the adjusting sleeve plate 4 rotates around the center of the main bracket 1, ensuring that the mounting seat 6 is located on the central axis of the main bracket 1. The mounting seat 6 being located on the central axis of the main bracket 1 ensures the overall stability, so that when the microphone is in a fixed state, the center of gravity is stable.
[0026] As Figure 1 and Figure 2 shown, in some embodiments, a wire bundler 39 is installed on the arc-shaped sleeve plate 2 and the adjusting sleeve plate 4. A flexible pad 40 is installed on the inner arc surface of the arc-shaped sleeve plate 2. The design of the flexible pad 40 enables the flexible pad 40 to effectively prevent discomfort caused by long-term wearing when the arc-shaped sleeve plate 2 is sleeved on the head, improving the wearing comfort. The wire bundler 39 is a conventional structure. In this embodiment, the data cable 13 has a reserved length to ensure that the data cable 13 has enough length when the adjusting sleeve plate 4 is rotated and the arc-shaped sleeve plate 2 is moved. A wire passing plate for the data cable 13 to pass through is constructed on the arc-shaped sleeve plate 2 where the adjusting sleeve plate 4 is installed, and a wire bundling plate is closely and slidably installed on the wire passing plate. Preferably, a U-shaped clamp is installed on another arc-shaped sleeve plate 2. As Figure 1 shown, the U-shaped clamp can effectively prevent the winding of the data cable 13 and can prevent the data cable 13 from dropping with gravity.
