Description

Technical Field

[0001] This invention relates to the technical field of headphones, and in particular to a microphone boom rotating structure and headphones. Background Technology

[0002] Over-ear headphones, as the name suggests, are headphones worn on the head. In over-ear headphones, the microphone boom assembly is rotatably connected to the earcups, and the microphone boom assembly is used to mount an external microphone.

[0003] To limit the rotation angle of the microphone assembly, a wear-resistant rotation limiting structure, i.e., a fixing member, is generally provided. The fixing member is fixedly sleeved on the screw, and the fixing member forms a first limiting block. The microphone assembly forms a second limiting block that matches the second limiting block. When the microphone assembly rotates to the maximum angle, the second limiting block abuts against the first limiting block to prevent the microphone assembly from continuing to rotate. For example, a rotation mechanism and headphones are disclosed in the invention patent application with application number CN202210716552.7.

[0004] However, the assembly of headphones requires the installation of a rotation limiting structure, which results in low assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a microphone rotating structure and a headset that improves assembly efficiency.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A microphone boom rotating structure includes an ear shell, a microphone boom assembly, a fastener, and a damping element. The ear shell has a connecting hole, the fastener passes through the connecting hole, and the damping element elastically abuts against the ear shell. The microphone boom assembly includes a mounting rod and a fastening insert. A rotating shaft protrudes from one side of the mounting rod and is rotatably connected to the connecting hole. The rotating shaft has a mounting hole. The fastening insert is located in the mounting hole and is covered and connected to the mounting rod. The fastening insert has a threaded hole. A first end of the fastener is threaded into the threaded hole, and a second end of the fastener elastically abuts against the damping element, so that the rotating shaft is rotatably connected to the connecting hole.

[0008] One end face of the fastening insert is provided with a rotating stop block, which also protrudes from the rotating shaft. The ear shell is provided with an anti-rotation block on the inner wall of the connecting hole.

[0010] In one embodiment, the earcup further includes a swing bracket mounted on the earcup and rotatably connected to a first end of the connecting rod, so that the earcup is swayingly connected to the first end of the connecting rod via the swing bracket.

[0011] In one embodiment, the swing bracket includes a connecting post and a locking member. The earmuff also has a recessed hole. The connecting post abuts against the earmuff. A first end of the connecting post has a fixing hole. The locking member passes through the recessed hole. The first end of the locking member is threaded into the fixing hole. The second end of the locking member abuts against the earmuff, so that the connecting post is fixedly connected to the earmuff through the locking member. The second end of the connecting post is rotatably connected to the first end of the connecting rod.

[0012] In one embodiment, the earmuff also has a positioning hole that communicates with the fixing hole, the first end of the connecting post is located in the positioning hole and is sleeved on the earmuff, and the first end face of the connecting post abuts against the groove wall of the positioning hole.

[0014] In one embodiment, a receiving groove is formed on one side of the ear cup, and at least a portion of the connecting rod is located within the receiving groove.

[0015] In one embodiment, the fastener has a wire outlet hole that communicates with the inner cavity of the microphone assembly.

[0016] In one embodiment, the microphone boom rotation structure further includes a microphone, a circuit board, a Hall switch, and a magnet. The microphone is installed inside the mounting rod, the circuit board is installed inside the ear shell, the Hall switch is electrically connected to the circuit board, and the Hall switch is also electrically connected to the microphone. The magnet is installed inside the microphone boom assembly, and the magnet is positioned opposite to the Hall switch when the microphone boom assembly rotates to a predetermined angle, so that the magnet is used to trigger the Hall switch to open.

[0017] A headset includes the microphone boom rotating structure described in any of the above embodiments.

[0034] This application provides a microphone rotating structure, including a housing, a microphone assembly, a fastener, and a damping element. The housing has a connecting hole, the fastener passes through the connecting hole, and the damping element elastically abuts against the housing. The microphone assembly includes a mounting rod and a fastening insert. A rotating shaft protrudes from one side of the mounting rod and is rotatably connected to the connecting hole. The rotating shaft has a mounting hole. The fastening insert is located in the mounting hole and is covered and connected to the mounting rod. The fastening insert has a threaded hole. The first end of the fastener is threaded into the threaded hole, and the second end of the fastener elastically abuts against the damping element. A rotating stop protrudes from one end face of the fastening insert and also protrudes from the rotating shaft. An anti-rotation block protrudes from the inner wall of the connecting hole on the housing.

[0035] In the aforementioned microphone rotation structure, a rotation stop is protruding from one end face of the fastening insert, and the rotation stop also protrudes from the rotation shaft. An anti-rotation block is protruding from the inner wall of the ear shell on the connecting hole. The anti-rotation block abuts against the rotation stop when the microphone assembly rotates to its maximum angle, making the fastening insert a rotation limiting structure and used to limit the rotation angle of the microphone assembly. Since the fastening insert is enclosed and connected inside the rotation shaft, there is no need to assemble the fastening insert when assembling the headphones, thus improving the assembly efficiency of the headphones.

[0036] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0037] like Figures 1 to 7 As shown, a microphone rotating structure 10 of one embodiment includes an ear shell 100, a microphone assembly 200, a fastener 300, and a damping element 400. The microphone assembly 200 includes a mounting rod 210 and a fastening insert 220. A rotating shaft 210a protrudes from one side of the mounting rod 210. The ear shell 100 has a connecting hole 101, and the rotating shaft 210a is rotatably connected to the connecting hole 101. The rotating shaft 210a forms a mounting hole 211. The fastening insert 220 is located in the mounting hole 211 and is covered and connected to the mounting rod 210. The fastening insert 220 has a threaded hole 221. The fastener 300 passes through the connecting hole 101, and the first end of the fastener 300 is threadedly connected to the threaded hole 221. The damping element 400 elastically abuts against the ear shell 100 and the second end of the fastener 300, respectively, so that the user has a damping sensation when rotating the microphone assembly 200. A rotating stop 220a is provided on one end face of the fastening insert 220. The rotating stop 220a also protrudes from the rotating shaft 210a. An anti-rotation block 100a is provided on the inner wall of the connecting hole 101 of the ear shell 100. The anti-rotation block 100a abuts against the rotating stop 220a when the microphone assembly 200 rotates to the maximum angle, so as to limit the rotation angle of the microphone assembly 200.

[0038] like Figure 4a As shown, in this embodiment, the rotating shaft 210a is located within the connecting hole 101 and rotatably connected to the ear shell 100. The fastening insert 220 is made of stainless steel; however, in other embodiments, the fastening insert 220 may also be made of ceramic or other existing high-strength materials. It is understood that the fastening insert 220 is encapsulated within the rotating shaft 210a of the mounting rod 210 of the microphone assembly 200 via in-mold injection molding. It is understood that the fastener 300 may be a screw, bolt, machine thread, or other existing threaded fastener 300.

[0039] The aforementioned microphone rod rotation structure 10 has a rotation stop 220a protruding from one end face of the fastening insert 220. The rotation stop 220a also protrudes from the rotation shaft 210a. The ear shell 100 has an anti-rotation block 100a protruding from the inner wall of the connecting hole 101. The anti-rotation block 100a abuts against the rotation stop 220a when the microphone rod assembly 200 rotates to its maximum angle, so that the fastening insert 220 is a rotation limiting structure and is used to limit the rotation angle of the microphone rod assembly 200. Since the fastening insert 220 is enclosed and connected inside the rotation shaft 210a, it is not necessary to assemble the fastening insert 220 when assembling the headphones, thus improving the assembly efficiency of the headphones.

[0040] like Figure 4a As shown, in one embodiment, the fastener 300 has a wire outlet hole 301, which communicates with the inner cavity of the microphone rod assembly 200. In this embodiment, the wires inside the microphone rod assembly 200 are led out through the wire outlet hole 301 in the fastener 300, so that the wires inside the microphone rod assembly 200 coincide with the fastener 300, thereby making the microphone rod rotating structure 10 more compact.

[0041] like Figure 3 As shown, in one embodiment, the microphone boom rotation structure 10 further includes a circuit board 500, a microphone, a Hall switch 600, and a magnet 700. The microphone is installed inside the mounting rod 210, the circuit board 500 is installed inside the earpiece 100, the Hall switch 600 is electrically connected to the circuit board 500, and the Hall switch 600 is also electrically connected to the microphone. The magnet 700 is installed inside the microphone boom assembly 200. When the microphone boom assembly 200 rotates to a predetermined angle, the magnet 700 is positioned opposite to the Hall switch 600 so that the magnet 700 can trigger the Hall switch 600 to open. In this embodiment, the Hall switch 600 is triggered by the magnet 700 to achieve the purpose of turning on the microphone. Since the magnet 700 does not touch the Hall switch 600 when triggering the switch, wear on the switch is avoided, and the service life of the switch is improved.

[0042] like Figure 3 and Figure 4a As shown, in one embodiment, the earcup 100 includes an earcup 110 and a connecting rod 120. The earcup 110 is pivotally connected to the first end of the connecting rod 120. A connecting hole 101 is formed in the connecting rod 120. A damping member 400 elastically abuts against the second ends of the connecting rod 120 and the fastener 300, respectively, so that the user has a damping sensation when rotating the microphone assembly 200. In this embodiment, the earcup 110 covers the user's ear. Since the earcup 110 is pivotally connected to the first end of the connecting rod 120, the angle of the earcup 110 is adjustable, allowing the earcup 110 to be adjusted to fit the user's ear, thus improving the comfort of wearing the headphones.

[0043] like Figure 1 As shown, in one embodiment, a receiving groove 102 is formed on one side of the ear cup 110, and at least a portion of the connecting rod 120 is located in the receiving groove 102, which improves the compactness of the microphone rod rotating structure 10.

[0044] like Figure 4b As shown, in another embodiment, the earcup 100 further includes a swing bracket 130, which is mounted on the earcup 110 and is rotatably connected to the first end of the connecting rod 120 so that the earcup 110 is swayed and connected to the first end of the connecting rod 120 via the swing bracket 130.

[0045] like Figure 4b As shown, in one embodiment, the swing bracket 130 includes a connecting post 131 and a locking member 132. The earmuff 110 also has a recessed hole 111. The connecting post 131 abuts against the earmuff 110. A fixing hole 1311 is formed at the first end of the connecting post 131. The locking member 132 passes through the recessed hole 111. The first end of the locking member 132 is threaded into the fixing hole 1311, and the second end of the locking member 132 abuts against the earmuff 110, so that the connecting post 131 is fixedly connected to the earmuff 110 by the locking member 132. The second end of the connecting post 131 is rotatably connected to the first end of the connecting rod 120. In this embodiment, when assembling the ear shell 100, the second end of the locking member 132 is sequentially inserted into the clearance hole 111 and the fixing hole 1311. Then, by twisting the locking member 132, the second end of the locking member 132 is threaded into the fixing hole 1311, and the second end of the locking member 132 abuts against the ear cup 110, thereby fixing the connecting post 131 to the ear cup 110. That is, the installation of the connecting post 131 can be completed by twisting the locking member 132, which improves the assembly efficiency of the connecting post 131 and thus improves the assembly efficiency of the headphones.

[0046] It is understood that the locking element 132 can be a screw, bolt, machine thread, or other existing threaded fastener 300.

[0047] like Figure 4b As shown, in one embodiment, the earcup 110 also has a positioning hole 112, which communicates with the fixing hole 1311. The first end of the connecting post 131 is located inside the positioning hole 112 and is sleeved on the earcup 110, with the first end face of the connecting post 131 abutting against the groove wall of the positioning hole 112. In this embodiment, when installing the connecting post 131, the connecting post 131 is first sleeved in the positioning hole 112, and then the locking member 132 is connected to the connecting post 131. Since the positioning hole 112 positions the connecting post 131, the alignment difficulty between the connecting post 131 and the locking member 132 is reduced, avoiding the problem of wasting time due to repeatedly adjusting the position of the connecting post 131, and improving the assembly accuracy of the headphones.

[0048] like Figure 4b As shown, in one embodiment, the swing bracket 130 further includes a connecting pin 133, and the second end of the connecting column 131 is rotatably connected to the first end of the connecting rod 120 through the connecting pin 133, so that the first end of the connecting rod 120 is rotatably connected to the connecting column 131.

[0049] like Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the connecting rod 120 includes a rod body 121 and a cover plate 122. An earpiece 110 is swayably connected to the first end of the rod body 121. The rod body 121 is formed in the connecting hole 101, and the rod body 121 also forms a receiving groove 1211, which communicates with the connecting hole 101. The cover plate 122 covers the receiving groove 1211 and is fixedly connected to the rod body 121. The cover plate 122 forms a receiving cavity between the inner walls of the receiving groove 1211, which is used to receive circuits and / or electronic components. A wire outlet channel 1213 is formed between the first end of the cover plate 122 and the first end of the rod body 121, for the wire to pass through. Further, a second wire outlet channel 1213 is formed on the second end face of the rod body 121 for the wire to pass through.

[0050] like Figure 1 As shown, in one embodiment, at least a portion of the connecting rod 120 is located within the receiving groove 102 and abuts against the groove wall of the receiving groove 102, so that the groove wall of the receiving groove 102 provides support for the connecting rod 120, reducing the probability of the connecting rod 120 being broken.

[0051] like Figure 6 and Figure 7 As shown, in one embodiment, the rod 121 has two spaced-apart mounting posts 121a protruding from the inner wall of the receiving groove 1211. Each mounting post 121a has a fastening hole 1212. The connecting rod 120 also includes two screws. The cover plate 122 has two clearance holes 1221. The two screws are respectively inserted into the two clearance holes 1221. The first ends of the two screws are respectively threaded into the two fastening holes 1212, and the second ends of the two screws are respectively abutted against the cover plate 122. This allows the cover plate 122 to be detachably connected to the rod 121 by the two screws, so as to facilitate the maintenance of the wiring and / or electronic components in the receiving cavity.

[0052] like Figure 8As shown, in one embodiment, the cover plate 122 has two spaced positioning posts 122a protruding from one side adjacent to the mounting posts 121a. Each positioning post 122a has a corresponding alignment hole 1222, which communicates with two clearance holes 1221. The diameter of each alignment hole 1222 is smaller than the diameter of the corresponding clearance hole 1221. The two mounting posts 121a are fitted into the two alignment holes 1222. In this embodiment, when installing the cover plate 122, the two mounting posts 121a are first fitted into the two alignment holes 1222, so that the two clearance holes 1221 correspond to the two fastening holes 1212. That is, the two alignment holes 1222 position the two mounting posts 121a respectively, avoiding repeated adjustments to the position of the cover plate 122, improving the installation efficiency of the cover plate 122, and thus improving the assembly efficiency of the headphones.

[0053] like Figure 7 and Figure 8 As shown, in one embodiment, a rotating post 121b protrudes from the rod 121 within the receiving groove 1211, and a connecting hole 101 is formed in the rotating post 121b. A damping member 400 elastically abuts against the rotating post 121b and the second end of the fastener 300, respectively, so that the rotating shaft 210a has a damping effect when rotating. In this embodiment, the rotating shaft 210a is located within the connecting hole 101 and sleeved with the rotating post 121b, which improves the uniformity of force distribution on the rotating shaft 210a and enhances the rotational smoothness of the rotating shaft 210a.

[0054] like Figure 7 and Figure 8 As shown, in one embodiment, the connecting hole 101 includes a connecting abutment hole 1011 and a limiting hole 1012. The diameter of the abutment hole 1011 is larger than the diameter of the limiting hole 1012. The anti-rotation block 100a protrudes from the inner wall of the limiting hole 1012. One end of the rotating shaft 210a is located in the abutment hole 1011 and is sleeved with the rod body 121. One end face of the rotating shaft 210a abuts against the inner wall of the abutment hole 1011, so that the abutment hole 1011 positions the rotating shaft 210a, thereby improving the installation efficiency of the rotating shaft 210a and thus improving the assembly efficiency of the headphones. Furthermore, the anti-rotation block 100a protrudes from the inner wall of the limiting hole 1012, and the rotation stop block 220a is located inside the limiting hole 1012. When the microphone assembly 200 rotates to the maximum angle, the rotation stop block 220a abuts against the anti-rotation block 100a to limit the maximum rotation angle of the microphone assembly 200.

[0055] like Figure 8 As shown, in one embodiment, the damping element 400 is a ring structure, so that the force on the fastener 300 and the connecting column 131 is more uniform, thereby improving the rotational smoothness of the meter rod assembly 200.

[0056] like Figure 8 As shown, further, a recessed groove 1214 is formed on the end face of the rotating column 121b opposite to the fastening insert 220, and a portion of the damping member 400 is embedded in the recessed groove 1214. In this embodiment, when installing the damping member 400, the damping member 400 is embedded in the recessed groove 1214, so that the damping member 400 is fixedly connected to the connecting column 131, which prevents the damping member 400 from falling off when installing the fastener 300, thereby avoiding repeated installation of the damping member 400 and improving the assembly efficiency of the headphones.

[0057] like Figure 8 As shown, in one embodiment, the connecting rod 120 also includes a decorative cover, which is disposed on the first end of the cover plate 122 so that the decorative cover covers the connecting structure on the first end of the connecting rod 120, thereby improving the aesthetics of the connecting rod 120.

[0058] like Figure 8 As shown, in one embodiment, there is a gap between the mounting rod 210 and the ear shell 100 to prevent the ear shell 100 from interfering with the rotation of the mounting rod 210.

[0059] like Figure 8 and Figure 9 As shown, in one embodiment, the peripheral wall of the fastening insert 220 is formed with a first annular groove 222. The inner wall of the first annular groove 222 is connected to and covers the rotating shaft 210a, meaning that a portion of the rotating shaft 210a is embedded in the first annular groove 222, thereby improving the connection strength between the fastening insert 220 and the rotating shaft 210a. Furthermore, the peripheral wall of the fastening insert 220 is also formed with a second annular groove 223. The first annular groove 222 and the second annular groove 223 communicate with each other. The inner wall of the second annular groove 223 is connected to and covers the rotating shaft 210a, meaning that a portion of the rotating shaft 210a is embedded in the second annular groove 223, further enhancing the connection strength between the fastening insert 220 and the rotating shaft 210a.

[0060] This application also provides a headset including the microphone rod rotating structure 10 described in any of the above embodiments. In one embodiment, the microphone rod rotating structure 10 includes an ear shell 100, a microphone rod assembly 200, a fastener 300, and a damping element 400. The microphone assembly 200 includes a mounting rod 210 and a fastening insert 220. A rotating shaft 210a protrudes from one side of the mounting rod 210. The ear shell 100 has a connecting hole 101. The rotating shaft 210a is rotatably connected to the connecting hole 101. The rotating shaft 210a forms the mounting hole 211. The fastening insert 220 is located in the mounting hole 211 and is covered and connected to the mounting rod 210. The fastening insert 220 has a threaded hole 221. A fastener 300 passes through the connecting hole 101. The first end of the fastener 300 is threaded into the threaded hole 221. The damping element 400 elastically abuts against the second end of the ear shell 100 and the fastener 300, respectively, so that the user has a damping sensation when rotating the microphone assembly 200. A rotating stop 220a is provided on one end face of the fastening insert 220. The rotating stop 220a also protrudes from the rotating shaft 210a. An anti-rotation block 100a is provided on the inner wall of the connecting hole 101 of the ear shell 100. The anti-rotation block 100a abuts against the rotating stop 220a when the microphone assembly 200 rotates to the maximum angle, so as to limit the rotation angle of the microphone assembly 200.

[0061] like Figure 4a As shown, in this embodiment, the rotating shaft 210a is located within the connecting hole 101 and rotatably connected to the ear shell 100. The fastening insert 220 is made of stainless steel; however, in other embodiments, the fastening insert 220 may also be made of ceramic or other existing high-strength materials. It is understood that the fastening insert 220 is encapsulated within the rotating shaft 210a of the mounting rod 210 of the microphone assembly 200 via in-mold injection molding. It is understood that the fastener 300 may be a screw, bolt, machine thread, or other existing threaded fastener 300.

[0062] In the aforementioned headphones, a rotation stop 220a is protruding from one end face of the fastening insert 220. The rotation stop 220a also protrudes from the rotation shaft 210a. An anti-rotation block 100a is protruding from the inner wall of the ear shell 100 in the connecting hole 101. The anti-rotation block 100a abuts against the rotation stop 220a when the microphone assembly 200 rotates to its maximum angle, so that the fastening insert 220 is a rotation limiting structure and is used to limit the rotation angle of the microphone assembly 200. Since the fastening insert 220 is enclosed and connected inside the rotation shaft 210a, it is not necessary to assemble the fastening insert 220 when assembling the headphones, thus improving the assembly efficiency of the headphones.

[0063] Compared with the prior art, the present invention has at least the following advantages:

[0064] The aforementioned microphone rod rotation structure 10 has a rotation stop 220a protruding from one end face of the fastening insert 220. The rotation stop 220a also protrudes from the rotation shaft 210a. The ear shell 100 has an anti-rotation block 100a protruding from the inner wall of the connecting hole 101. The anti-rotation block 100a abuts against the rotation stop 220a when the microphone rod assembly 200 rotates to its maximum angle, so that the fastening insert 220 is a rotation limiting structure and is used to limit the rotation angle of the microphone rod assembly 200. Since the fastening insert 220 is enclosed and connected inside the rotation shaft 210a, it is not necessary to assemble the fastening insert 220 when assembling the headphones, thus improving the assembly efficiency of the headphones.
