Description

Technical Field

[0001] This disclosure relates to the technical field of headphone control, and in particular to a three-way operating switch structure and a headphone. Background Technology

[0002] In the field of electronic devices such as headphones, control switches are key components for user interaction and function adjustment. Traditional headphone control switch designs have many limitations, typically using multiple independent buttons or switches to achieve different functions such as volume adjustment, play / pause, and song switching. This design results in a large number of switches distributed across the device's surface, increasing its footprint and making it difficult to achieve a clean and aesthetically pleasing overall design. Furthermore, it forces users to frequently switch between multiple buttons or switches with different functions, making the operation process cumbersome and reducing the user experience. In addition, traditional toggle switches rely on circular or large-angle arc movements, which, due to their structural limitations, require a large curved operating space on the device's surface, further restricting the device's appearance design. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a three-way operating switch structure and earphone that reduces the number of switches and space occupation, and is easy to operate.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0005] A three-way operating switch structure includes a switch housing, a printed circuit board assembly, a gear assembly, a toggle switch assembly, and a sliding push-touch assembly. The switch housing has an assembly receiving cavity, and the printed circuit board assembly is fixed in the assembly receiving cavity.

[0006] The oscillating switch assembly is disposed on the printed circuit board assembly and is electrically connected to the printed circuit board assembly. The gear assembly includes a driven gear and a snap-fit ​​housing. A portion of the oscillating switch assembly is snapped into the interior of the snap-fit ​​housing. The driven gear is connected to the side of the snap-fit ​​housing adjacent to the sliding push-twist assembly. The sliding push-twist assembly includes a sliding push-twist element and a drive rack. The drive rack is connected to the side of the sliding push-twist element adjacent to the oscillating switch assembly. The driven gear meshes with the drive rack. The switch housing also has a sliding through groove, and the sliding push-twist element is slidably disposed within the sliding through groove.

[0007] In one embodiment, the rocking switch assembly includes a rocking switch component and a switch connector. The switch connector is electrically connected to the printed circuit board assembly. The rocking switch component is rotatably connected to the switch connector. The snap-fit ​​housing has a switch receiving cavity, and the rocking switch component is snapped into the switch receiving cavity.

[0008] In one embodiment, the swing switch is provided with at least one snap-fit ​​element, the snap-fit ​​housing is provided with at least one snap-fit ​​groove, the snap-fit ​​groove is connected to the switch receiving cavity, and each snap-fit ​​element snaps into one of the snap-fit ​​grooves.

[0009] In one embodiment, the snap-fit ​​housing is an arc-shaped housing that is adapted to the outer contour of the switch connector.

[0010] In one embodiment, the ratio of the number of teeth of the driving rack to that of the driven gear is 1:1.

[0011] In one embodiment, the sliding push-twist component includes a limiting sub-component and a sliding sub-component. The limiting sub-component is connected to the sliding sub-component and abuts against the switch housing. The sliding sub-component is slidably disposed within the sliding through groove.

[0017] The aforementioned three-way operation switch structure allows users to easily adjust headphone volume and control multiple functions by simply pushing the sliding knob component to the left or right and pressing it in the middle. This eliminates the need to switch between multiple buttons or switches with different functions, allowing the compact switch structure to integrate multiple functions such as volume adjustment, play / pause, and song switching.

[0025] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0026] like Figures 1 to 3As shown, a three-way operating switch structure 10 according to an embodiment of the present disclosure includes a switch housing 100, a printed circuit board assembly 200, a gear assembly 300, a toggle switch assembly 400, and a sliding push-twist assembly 500. The switch housing 100 has an assembly receiving cavity 1001, and the printed circuit board assembly 200 is fixed in the assembly receiving cavity 1001.

[0027] The oscillating switch assembly 400 is disposed on the printed circuit board assembly 200 and is electrically connected to the printed circuit board assembly 200. The gear assembly 300 includes a driven gear 310 and a snap-fit ​​housing 320. Part of the oscillating switch assembly 400 is snapped into the interior of the snap-fit ​​housing 320. The driven gear 310 is connected to the side of the snap-fit ​​housing 320 adjacent to the sliding push-twist assembly 500. The sliding push-twist assembly 500 includes a sliding push-twist member 510 and a drive rack 520. The drive rack 520 is connected to the side of the sliding push-twist member 510 adjacent to the oscillating switch assembly 400. The driven gear 310 meshes with the drive rack 520. The switch housing 100 is also provided with a sliding through groove 1002, and the sliding push-twist member 510 is slidably disposed in the sliding through groove 1002.

[0028] In this embodiment, when the user needs to adjust the headphone volume, a left-right force is applied to the sliding push-twist member 510 of the sliding push-twist assembly 500. The sliding push-twist member 510 moves left and right along the sliding through groove 1002 opened on the switch housing 100. Since the active rack 520 is connected to the side of the sliding push-twist member 510 adjacent to the head-shaking switch assembly 400, the movement of the sliding push-twist member 510 will drive the active rack 520 to move synchronously. The driven gear 310 of the gear assembly 300 meshes with the active rack 520, and the movement of the active rack 520 will drive the driven gear 310 to rotate.

[0029] Furthermore, a portion of the head-shaking switch assembly 400 is snapped into the snap-fit ​​housing 320 of the gear assembly 300. The driven gear 310 is connected to the side of the snap-fit ​​housing 320 adjacent to the sliding push-twist assembly 500. Rotation of the driven gear 310 transmits power to the snap-fit ​​housing 320, thereby causing the head-shaking switch assembly 400 to perform an arc-shaped motion. During this arc-shaped motion, the electrical connection between the head-shaking switch assembly 400 and the printed circuit board assembly 200 changes. This change is converted into a corresponding electrical signal by the circuit. The printed circuit board assembly 200 transmits this electrical signal to devices such as headphones to achieve volume + or volume - control functions.

[0030] Specifically, if the user applies a force to the sliding push-twist component 510 to push it to the left, the active rack 520 moves to the left, causing the driven gear 310 to rotate counterclockwise (assuming the viewpoint is from the sliding push-twist component 500 to the head-shaking switch component 400), and the head-shaking switch component 400 moves to the left in an arc, outputting a volume- control signal; if the sliding push-twist component 510 is pushed to the right, the active rack 520 moves to the right, causing the driven gear 310 to rotate clockwise, and the head-shaking switch component 400 moves to the right in an arc, outputting a volume-+ control signal.

[0031] When a user needs to perform multi-functional controls on the headphones, such as play / pause music or switch songs, they can press the sliding push button 510 of the sliding push button assembly 500. At this time, the sliding push button 510 transmits the pressing force to the snap-fit ​​housing 320 of the gear assembly 300, which in turn acts on the pressure sensor inside the head-shake switch assembly 400. After sensing the pressing pressure, the pressure sensor transmits the pressure signal in real time to the printed circuit board assembly 200 through the electrical connector on the head-shake switch assembly 400. Then, the printed circuit board assembly 200 analyzes and processes the received pressure signal, converting it into a corresponding control electrical signal according to a preset signal correspondence logic. For example, a short press of the sliding push button 510 corresponds to play or pause after processing; two consecutive short presses switch to the next song; and three consecutive short presses switch to the previous song. Subsequently, the printed circuit board assembly 200 transmits the above control electrical signals to the headphones, thereby realizing preset multi-functional control functions such as playing / pausing music and switching to the previous / next song, to meet the user's diverse operational needs for the headphones.

[0032] The aforementioned three-way operation switch structure 10 allows users to adjust the headphone volume and perform multiple functions simply by operating the sliding push-twist component of the sliding push-twist assembly, pushing left and right and pressing in the middle. This eliminates the need to switch between multiple buttons or switches with different functions, thus integrating volume adjustment, play / pause, song switching, and other functions into a compact switch structure. It also reduces the number of switches on the device and the space occupied, making the headphone design more concise and aesthetically pleasing, and ultimately helping to reduce production costs.

[0033] like Figures 1 to 3As shown, in one embodiment, the head-shaking switch assembly 400 includes a swing switch 410 and a switch connector 420. The switch connector 420 is electrically connected to the printed circuit board assembly 200. The swing switch 410 is rotatably connected to the switch connector 420. The snap-fit ​​housing 320 has a switch receiving cavity 3201, and the swing switch 410 is snapped into the switch receiving cavity 3201. In this embodiment, when the user rotates the snap-fit ​​housing 320 by operating the sliding push-twist assembly 500, the swing switch 410 swings in an arc in the corresponding direction. This swing directly changes its relative position and connection state with the printed circuit board assembly 200, thereby triggering different electrical signal outputs to achieve functions such as volume adjustment and multi-function control. The switch connector 420 maintains a stable electrical connection with the printed circuit board assembly 200, providing a bridge for the entire head-shaking switch assembly 400 to connect to the circuit system, ensuring that the electrical signals generated by the movement of the swing switch 410 can be accurately and stably transmitted to the printed circuit board assembly 200, and then transmitted to devices such as headphones. On the other hand, the switch connector 420 serves as the rotational connection base for the swing switch 410, providing a reliable rotational support point for the swing switch 410, ensuring that the swing switch 410 can perform arc motion, while also fixing the swing switch 410 in a suitable position, thereby ensuring the stability and reliability of the entire switch structure.

[0034] like Figures 1 to 3 As shown, in one embodiment, the swing switch 410 is provided with at least one snap-fit ​​element 411, and the snap-fit ​​housing 320 has at least one snap-fit ​​groove 3202. The snap-fit ​​groove 3202 communicates with the switch receiving cavity 3201, and each snap-fit ​​element 411 snaps into one of its snap-fit ​​grooves 3202. In this embodiment, when the snap-fit ​​housing 320 rotates under the drive of the driven gear 310, due to the tight fit between the snap-fit ​​element 411 and the snap-fit ​​groove 3202, the rotation of the snap-fit ​​housing 320 can be accurately transmitted to the swing switch 410, allowing the swing switch 410 to swing in an arc according to a predetermined trajectory and angle, thereby ensuring the accuracy of volume adjustment and multi-function control functions. Specifically, the snap-fit ​​structure of the snap-fit ​​element 411 and the snap-fit ​​groove 3202 provides reliable connection strength and can withstand various stresses generated by the swing switch 410 during movement. When the user frequently operates the sliding push-twist assembly 500, the swing switch 410 will continuously swing in an arc. The snap-fit ​​structure ensures that the swing switch 410 is always firmly connected in the snap-fit ​​housing 320, and there will be no loosening or falling off, thereby ensuring the stability and reliability of the entire switch structure.

[0035] like Figures 1 to 3As shown, in one embodiment, the snap-fit ​​housing 320 is an arc-shaped housing, which is adapted to the outer contour of the switch connector 420. In this embodiment, the operation of a traditional toggle switch relies on circular or large-angle arc motion. Its operating trajectory is limited by its own structure, requiring a large arc-shaped operating space to be reserved on the surface of the device. This not only increases the limitations of the device's appearance design but also requires the user to adapt to a non-linear force application method. In this embodiment, through the precise adaptation of the arc-shaped housing and the switch connector 420, combined with the rack and pinion transmission structure of the gear assembly 300 and the sliding push-twist assembly 500, the left and right translational force applied by the user to the sliding push-twist assembly 510 is converted into the arc motion of the toggle switch assembly 400. When the sliding push-twist assembly 510 moves in a straight line, the displacement of the driving rack 520 is precisely converted into the rotation angle of the driven gear 310 through gear meshing, and then transmitted to the swing switch assembly 410 through the arc-shaped housing, so that the arc motion angle of the toggle switch assembly 400 and the push-twist sliding distance form a linear correspondence.

[0036] like Figures 1 to 3 As shown, in one embodiment, the tooth ratio of the driving rack 520 to the driven gear 310 is 1:1. In this embodiment, when the user operates the sliding push-touch component 510, the driving rack 520 moves accordingly. Since the tooth ratio of the driving rack 520 to the driven gear 310 is 1:1, for every tooth pitch moved by the driving rack 520, the driven gear 310 will rotate by the corresponding angle of one tooth pitch. This precise transmission relationship allows the user's operation of the sliding push-touch component 510 to be accurately converted into the arc motion of the head-shaking switch assembly 400, thereby improving the user's control precision of volume adjustment.

[0037] like Figures 1 to 3 As shown, in one embodiment, the sliding push-twist member 510 includes a limiting sub-member 511 and a sliding sub-member 512. The limiting sub-member 511 is connected to the sliding sub-member 512 and abuts against the switch housing 100. The sliding sub-member 512 is slidably disposed within the sliding through groove 1002. In this embodiment, the limiting sub-member 511 abuts against the switch housing 100. When the sliding sub-member 512 slides within the sliding through groove 1002, the limiting sub-member 511 acts as a blocking element. When the sliding sub-member 512 slides to the edge of the sliding through groove 1002, the contact between the limiting sub-member 511 and the switch housing 100 restricts the tendency of the sliding sub-member 512 to continue sliding outward, effectively preventing the sliding sub-member 512 from dislodging from the sliding through groove 1002. This ensures the stability of the overall structure of the sliding push-twist member 510, keeping it always within a preset sliding range, thereby ensuring the normal operation of the entire three-way operating switch structure 10.

[0038] like Figures 1 to 3As shown, in one embodiment, the sliding push-torque member 510 further includes a fixing member 513. One end of the fixing member 513 is connected to the driving rack 520, and the other end is connected to the limiting member 511. In this embodiment, since the fixing member 513 connects the driving rack 520 and the limiting member 511, the driving rack 520 will not wobble or deviate during movement. When the driving rack 520 meshes with the driven gear 310, the stable driving rack 520 can ensure precise meshing with the driven gear 310, avoiding problems such as uneven transmission, jamming, or even gear damage caused by rack wobble, thereby improving the reliability and durability of the entire transmission system.

[0039] like Figures 1 to 3 As shown, in one embodiment, the swing switch 410 is provided with an abutment boss 412, which abuts against the inner wall of the switch receiving cavity 3201. In this embodiment, when the snap-fit ​​housing 320 drives the swing switch 410 to make an arc motion, the swing switch 410 may have a radial offset tendency due to inertia or force. The tight abutment between the abutment boss 412 and the inner wall of the switch receiving cavity 3201 can effectively limit this offset, ensuring that the swing switch 410 always moves along the preset arc trajectory, avoiding transmission errors caused by positional offset, thereby ensuring the linear correspondence of the electrical signal output when adjusting the volume and improving the accuracy of user operation.

[0040] like Figures 1 to 3 As shown, in one embodiment, the switch connector 420 has multiple circuit board connectors 421, which are spaced apart and electrically connected to the printed circuit board assembly 200. In this embodiment, the multiple circuit board connectors 421 are spaced apart, forming a multi-point electrical connection between the switch connector 420 and the printed circuit board assembly 200. Compared with a single-point connection, this multi-point connection method can significantly reduce the risk of electrical connection interruption due to loosening, oxidation, or external interference at a single connection point. Even if one or more circuit board connectors 421 have connection problems, other normal connection points can still ensure the electrical signal transmission between the switch connector 420 and the printed circuit board assembly 200, thereby improving the electrical connection stability of the entire three-way operating switch structure 10 and ensuring the reliable implementation of functions such as volume adjustment and multi-function control.

[0041] This application also provides an earphone, including a three-way operating switch structure 10 according to any embodiment. In this embodiment, when the user needs to adjust the earphone volume, a left-right force is applied to the sliding push-twist member 510 of the sliding push-twist assembly 500. The sliding push-twist member 510 moves left and right along the sliding through groove 1002 opened on the switch housing 100. Since the active rack 520 is connected to the side of the sliding push-twist member 510 adjacent to the head-shaking switch assembly 400, the movement of the sliding push-twist member 510 will drive the active rack 520 to move synchronously. The driven gear 310 of the gear assembly 300 meshes with the active rack 520, and the movement of the active rack 520 will drive the driven gear 310 to rotate. Furthermore, a portion of the head-shaking switch assembly 400 is snapped into the snap-fit ​​housing 320 of the gear assembly 300. The driven gear 310 is connected to the side of the snap-fit ​​housing 320 adjacent to the sliding push-twist assembly 500. Rotation of the driven gear 310 transmits power to the snap-fit ​​housing 320, thereby causing the head-shaking switch assembly 400 to perform an arc-shaped motion. During this arc-shaped motion, the electrical connection between the head-shaking switch assembly 400 and the printed circuit board assembly 200 changes. This change is converted into a corresponding electrical signal by the circuit. The printed circuit board assembly 200 transmits this electrical signal to devices such as headphones to achieve volume + or volume - control functions. Specifically, if the user applies force to the sliding push knob 510, pushing it to the left, the active rack 520 moves to the left, causing the driven gear 310 to rotate counterclockwise, and the head-shaking switch assembly 400 to move in an arc to the left, outputting a volume-down control signal. If the user pushes the sliding push knob 510 to the right, the active rack 520 moves to the right, causing the driven gear 310 to rotate clockwise, and the head-shaking switch assembly 400 to move in an arc to the right, outputting a volume-up control signal. When the user needs to perform multi-functional control of the headphones, such as play / pause music, switch songs, etc., they can press the center of the sliding push knob 510 of the sliding push knob assembly 500. Since the sliding push knob 510 and the head-shaking switch assembly 400 are structurally related, when the sliding push knob 510 is pressed, the force will be applied directly to the pressable part in the center of the head-shaking switch assembly 400. When the center position of the toggle switch assembly 400 is pressed, its electrical connection with the printed circuit board assembly 200 changes again, generating a corresponding electrical signal through the circuit. The printed circuit board assembly 200 transmits this electrical signal to devices such as headphones to achieve multi-functional control.

[0042] Compared with the prior art, this disclosure has at least the following advantages:

[0043] The aforementioned three-way operation switch structure 10 allows users to adjust the headphone volume and perform multiple functions simply by operating the sliding push-twist component of the sliding push-twist assembly, pushing left and right and pressing in the middle. This eliminates the need to switch between multiple buttons or switches with different functions, thus integrating volume adjustment, play / pause, song switching, and other functions into a compact switch structure. It also reduces the number of switches on the device and the space occupied, making the headphone design more concise and aesthetically pleasing, and ultimately helping to reduce production costs.

[0044] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
