Description

Technical Field

[0001] This utility model relates to the technical field of headphone products, and in particular to a rotating control mute structure and headphones. Background Technology

[0002] With technological advancements, especially the widespread adoption of communication and remote collaboration, headphones are no longer just for receiving sound; they are also used for real-time sound acquisition and transmission. To address various usage scenarios, over-ear headphones often feature a physical mute switch, allowing users to toggle the mute mode on or off, thus controlling the microphone's on / off state. Currently, the mute switch structure for over-ear headphones primarily involves a separate control box within the headphone cable, consisting of top and bottom covers, buttons, a PCB, and wiring. Components such as the in-line control buttons require specialized molds for production, resulting in higher costs. The separate control box's component structure is relatively complex, demanding sophisticated assembly processes. Furthermore, in scenarios requiring quick switching to mute mode, the process of locating the in-line control buttons can negatively impact overall ease of operation.

[0003] To address the aforementioned issues, existing technologies for headphones can replace button switches with improvements to the microphone boom connection structure to control mute mode switching. For example, Chinese patent document CN216313369U discloses a microphone boom rotary contact switch structure and headphones, including a microphone boom assembly, a microphone boom connector, a headphone housing, a headphone main control board, and a rotary trigger switch. The first side of the microphone boom connector is connected to the microphone boom assembly, and the second side is rotatably connected to the headphone housing and has a contact portion. The headphone main control board is installed inside the headphone housing, and the rotary trigger switch is installed on the headphone main control board. Rotating the microphone boom assembly drives the microphone boom connector to rotate, causing the contact portion to trigger the rotary trigger switch. This solution eliminates the need for a button trigger switch, improving ease of use. However, the tactile feedback provided during headphone mode switching is only achieved through contact between the contact portion and the rotary trigger switch, resulting in unclear tactile feedback and poor consistency in mass production. Furthermore, the direct rotatable connection between the microphone boom connector and the headphone housing places high demands on the headphone housing's processing and can easily cause wear and tear during mode switching.

[0004] In summary, among the existing solutions involving the control of switching the mute mode of headphones, the use of in-line control buttons has the problems of high production costs, complex assembly processes, and insufficient convenience; while the existing microphone rotation structure has insufficient and unreliable tactile feedback, poor consistency in mass production, and high processing requirements for the headphone shell, making it prone to wear. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a rotary control mute structure and headphones that can make operation more convenient and tactile feedback clearer and more reliable when switching to mute mode, while reducing production costs and improving maintainability.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A rotary control silent structure, comprising at least: The earphone housing has an internal main control board, which is equipped with a mute trigger switch. The microphone lever is provided with a connecting part, and the connecting part is provided with a contact part that matches the mute trigger switch; It also includes a rotating connection assembly, which includes a rotating tray and a rotating cover rotatably connected to the rotating tray. The rotating tray is fixedly connected to the earphone housing, and the rotating cover is fixedly connected to the connecting part. The rotating connection assembly is also provided with an elastic part and a pressing protrusion that matches the elastic part.

[0007] The beneficial effects of this plan are:

[0008] (1) Compared with the existing technology that uses a push-button switch, this utility model connects the headphone shell and the microphone rod respectively through a rotating bracket and a rotating cover in a rotating connecting assembly. The rotating bracket and rotating cover are rotatably connected, and the microphone rod can be moved to rotate the contact part relative to the headphone shell. When the contact part rotates and contacts the mute trigger switch, the headphone turns on the mute mode; when the contact part rotates and releases contact with the mute trigger switch, the headphone turns off the mute mode, thereby achieving quick switching of the mute mode and convenient operation. In addition, this utility model does not require separate manufacturing of in-line control buttons and control boxes, resulting in lower production costs.

[0009] (2) Compared with the existing technology, which uses the microphone rod connector to directly rotate and connect to the earphone shell, this utility model uses a rotating cover and a rotating bracket to rotate and connect, which reduces the processing requirements of the earphone shell and avoids wear on the earphone shell when switching modes, thereby further reducing production costs and improving maintainability.

[0010] (3) The present invention provides an elastic part and a pressing protrusion on the rotating connection component. When the point contact part touches the mute trigger switch, the elastic part is pressed by the pressing protrusion. At this time, the damping change generated by the elastic deformation of the elastic part can provide clear tactile feedback to prompt the operator that the headphones will turn on the mute mode, making the operation clearer and more reliable.

[0011] Furthermore, a central post is provided on one side of the connecting part that connects to the rotating cover, and a rotating through hole that cooperates with the central post is provided in the middle of the rotating support. The central post passes through the rotating through hole and connects to the rotating cover.

[0012] Furthermore, the extrusion protrusion is disposed on the rotating support, the elastic part is disposed on the rotating cover, and the elastic part is provided with an elastic cantilever.

[0013] Furthermore, a first friction plate is provided between the connecting part and the rotating support.

[0014] Furthermore, a second friction plate is provided between the rotating cover and the rotating support.

[0015] Furthermore, the outer side wall of the rotating support is provided with an upper limit protrusion and a lower limit protrusion, and the inner side wall of the connecting part is provided with a limiting boss located between the upper limit protrusion and the lower limit protrusion.

[0016] The beneficial effect of this solution is that, during the rotation of the microphone lever relative to the earphone housing, when one side of the limiting protrusion abuts against the upper limit protrusion of the rotating head, this position is the upper limit position of the microphone lever; conversely, during the rotation of the microphone lever relative to the earphone housing, when the other side of the limiting protrusion abuts against the lower limit protrusion of the rotating head, this position is the lower limit position of the microphone lever. Therefore, by using the upper and lower limit protrusions and the limiting protrusion to set the upper and lower limit positions of the microphone lever, it is possible to prevent the microphone lever from being damaged due to excessive rotation.

[0017] Furthermore, the extruded protrusion is a screw mounting post.

[0018] The beneficial effect of this solution is that its screw mounting post is used to fix the screw that mounts the rotating bracket to the earphone housing. It combines the functions of the extrusion protrusion and the screw mounting post, which simplifies the structure of the rotating bracket and reduces the complexity of the mold and the production cost.

[0019] Furthermore, the elastic part is arched in shape, and the elastic cantilever is a protrusion on the arch.

[0020] Furthermore, the rotating support has an annular groove on the side that contacts the second friction plate, and a silicone ring for supporting the second friction plate is provided in the annular groove.

[0021] This utility model also provides an earphone, which includes at least the above-mentioned rotation control mute structure. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0036] like Figure 1-2 As shown, this embodiment of a rotary control mute structure includes an earphone housing 1 and a microphone boom 2. The earphone housing 1 houses an earphone main control board 3, which includes a mute trigger switch 4. The microphone boom 2 has a connecting portion 21, which has a contact portion 211 that matches the mute trigger switch 4. Preferably, in this embodiment, the mute trigger switch 4 is a push-button switch. When the button of the mute trigger switch 4 is pressed, the earphone main control board 3 activates the mute mode, and the microphone on the microphone boom 2 stops transmitting sound. When the button of the mute trigger switch 4 is released, the earphone main control board 3 deactivates the mute mode, and the operator can then transmit sound through the microphone on the microphone boom 2.

[0037] It should be noted that in this embodiment, the mute trigger switch 4 is a push-button switch, which is merely a preferred embodiment. Those skilled in the art should understand that the mute trigger switch 4 can be selected according to actual needs. Furthermore, the specific structure and working principle of the circuit used to set the mute mode on the headphone main control board 3 are well known and mastered by those skilled in the art, and will not be described in detail in this embodiment.

[0038] As a special feature of this embodiment, such as Figure 3-4As shown, it includes a rotating connection assembly 5. The rotating connection assembly 5 includes a rotating bracket 51 and a rotating cover 52. The rotating bracket 51 and the rotating cover 52 are rotatably connected. The rotating bracket 51 is fixedly connected to the earphone housing 1 by screws. The rotating cover 52 is fixedly connected to the connecting part 21 by screws. The rotating connection assembly 5 is also provided with an elastic part 521 and a pressing protrusion 512 that matches the elastic part 521.

[0039] The advantage of this design is that, in this embodiment, the rotating bracket 51 and rotating cover 52 in the rotating connecting assembly 5 are respectively connected to the connecting part 21 of the earphone shell 1 and the microphone rod 2. The rotating bracket 51 and rotating cover 52 are rotatably connected, allowing the microphone rod 2 to rotate the contact part 211 relative to the earphone shell 1. When the contact part 211 rotates and contacts the mute trigger switch 4, the earphone enters the mute mode; when the contact part 211 rotates and releases contact with the mute trigger switch 4, the earphone exits the mute mode, thus achieving quick switching between mute modes and convenient operation. Furthermore, this embodiment does not require separate fabrication of in-line control buttons and a control box, resulting in lower production costs.

[0040] Another advantage of this arrangement is that, in this embodiment, the rotating bracket 51 and the rotating cover 52 are connected by rotation, which reduces the processing requirements of the earphone shell 1 and avoids wear on the earphone shell 1 when switching modes, thereby further reducing production costs and improving maintainability.

[0041] Another advantage of this design is that, in this embodiment, the rotating connection component 5 is provided with an elastic part 521 and a pressing protrusion 512. When the touch part 211 contacts the mute trigger switch 4, the elastic part 521 is pressed by the pressing protrusion 512. At this time, the damping change generated by the elastic deformation of the elastic part 521 can provide clear tactile feedback to prompt the operator that the headphones will turn on the mute mode, making the operation clearer and more reliable.

[0042] Preferably, in this embodiment, the extrusion protrusion 512 is disposed on the outer end face of the rotating support 51, such as... Figure 3 , Figure 4 and Figure 6 As shown. Further, in this embodiment, the elastic portion 521 is disposed on the outer end face of the rotating cover 52, and an elastic cantilever 5211 is provided on the elastic portion 521, as shown. Figure 3 , Figure 4 and Figure 9 As shown. Further, in this embodiment, the elastic part 521 is arched, and the elastic cantilever 5211 is a protrusion on the arch. During the process of the contact part 211 contacting the silent trigger switch 4, the elastic cantilever 5211 contacts and squeezes the protrusion 512, causing the elastic part 521 to undergo elastic deformation and providing obvious resistance feedback.

[0043] It should be noted that in this embodiment, the extrusion protrusion 512 is disposed on the rotating support 51, and the elastic part 521 is disposed on the rotating cover 52. This is only a preferred embodiment of this embodiment. Those skilled in the art should understand that the extrusion protrusion 512 can also be disposed on the rotating cover 52, and the elastic part 521 can be disposed on the rotating support 51.

[0044] Preferably, in this embodiment, during the process of the elastic cantilever 5211 contacting the extrusion protrusion 512, the elastic part 521 undergoes elastic deformation from the beginning to the restoration of its shape, and the rotating angle of the microphone 2 is 30 degrees.

[0045] Preferably, in this embodiment, the structure of the connecting part 21 of the microphone rod 2 is as follows: Figure 5 As shown. A central post 212 is provided on one side of the connecting rotating cover 52 of the connecting part 21, and a positioning post 214 is provided on the central post 212. A limiting boss 213 is provided on the inner side wall of the connecting part 21. Further, in this embodiment, the contact part 211 is provided on the edge of the other side of the connecting part 21.

[0046] Preferably, in this embodiment, the structure of the rotating support 51 is as follows: Figure 6 As shown. The rotating support 51 has a rotating through hole 511 in the middle that cooperates with the central column 212, and the outer side wall of the rotating support 51 has an upper limit protrusion 513 and a lower limit protrusion 514.

[0047] It should be noted that in this embodiment, the limiting boss 213 is located between the upper limiting boss 513 and the lower limiting boss 514, and is used to set the upper and lower limit positions of the microphone rod 2. During the process of the microphone rod 2 driving the limiting boss 213 to rotate relative to the earphone housing 1, when one side of the limiting boss 213 abuts against the upper limiting boss 513 of the rotating support 51, the microphone rod 2 is at its upper limit position. The structure of the rotating support 51 and the connecting part 21 is as follows... Figure 7 As shown. Conversely, during the process where the microphone rod 2 reverses and drives the limiting boss 213 to rotate relative to the earphone housing 1, when the other side of the limiting boss 213 abuts against the lower limiting protrusion 514 of the rotating support 51, the microphone rod 2 is at its lower limit position, and the structure of the rotating support 51 and the connecting part 21 is as follows. Figure 8 As shown.

[0048] The advantage of this configuration is that, in this embodiment, the upper limit position and the lower limit position of the microphone lever 2 are set by the upper limit protrusion 513, the lower limit protrusion 514 and the limiting protrusion 213, so as to prevent the microphone lever 2 from being damaged by excessive rotation.

[0049] Preferably, in this embodiment, the extrusion protrusion 512 is a screw mounting post. The screw mounting post is used to secure the screws that mount the rotating bracket 51 onto the earphone housing 1.

[0050] The advantage of this design is that it combines the functions of the extrusion protrusion 512 and the screw mounting post, which simplifies the structure of the rotating support 51 and reduces the complexity of the mold and production costs.

[0051] It should be noted that in this embodiment, the extrusion protrusion 512 is a screw mounting post, which is only a preferred embodiment of this embodiment. Those skilled in the art should understand that the extrusion protrusion 512 can also be set separately from the screw mounting post, and the screw mounting post can be set outside the movement range of the elastic cantilever 5211 and not in contact with the elastic cantilever 5211.

[0052] Preferably, in this embodiment, the rotating support 51 has an annular groove 515 on the side facing the outer end face, and the annular groove 515 is used to place the silicone ring 8.

[0053] Preferably, in this embodiment, the structure of the rotating cover 52 is as follows: Figure 9 As shown. The rotating cover 52 is provided with a positioning hole 522 that cooperates with the positioning post 214.

[0054] Preferably, in this embodiment, the internal structure of the rotary connecting assembly 5 when connected to the connecting part 21 is as follows: Figure 10 As shown.

Further, the positioning post 214 of the connecting part 21 cooperates with the positioning hole 522 of the rotating cover 52.

[0055] Preferably, in this embodiment, a first friction plate 6 is provided between the connecting part 21 and the rotating support 51, and a second friction plate 7 is provided between the rotating cover 52 and the rotating support 51.
