Technical Field

[0001] This disclosure relates to the technical field of audio playback devices, and in particular to a headphone controller and headphones. Background Technology

[0002] In recent years, with the widespread adoption of high-resolution audio equipment, headphone controllers, as key devices for improving sound quality, have gradually moved from the professional field to the mass consumer market. Existing headphone controllers typically feature a layout where the screen, buttons, and knobs are separate components, resulting in a clear interface and intuitive operation.

[0003] However, the aforementioned layout design often occupies a large panel space, which not only increases the complexity of the structure but also directly increases the size of the headphone controller. This places higher demands on the user's desktop space and limits the miniaturization of headphone controllers. Summary of the Invention

The rotating ring is disposed inside the knob cap and connected to the inner wall of the knob cap. The screen bracket is located at the end of the rotating ring opposite to the circuit board bracket, and the screen bracket is rotatably connected to the rotating ring. The circuit board bracket has a through hole. The control component includes a circuit board, an encoder, and a button component. The encoder is located on the side of the circuit board facing away from the base, and the button component is located on the side of the circuit board facing the base. When the tactile feedback component is pressed down to a predetermined position, the button component is triggered to generate a button signal. The encoder is inserted into the through hole, and the rotating ring is sleeved on the outside of the encoder and is driven to cooperate with the rotation trigger end of the encoder to trigger the encoder to generate a knob signal when the rotating ring rotates. A screen assembly is disposed at one end of the screen bracket away from the rotating ring, and the screen assembly is electrically connected to the circuit board.

[0006] In one embodiment, the tactile feedback component has a through hole that passes through the circuit board bracket, the rotating ring, and the screen bracket in sequence. The bracket is provided with a guide post corresponding to the through hole. The tactile feedback component is sleeved on the guide post through the through hole and slides along the guide post so that the tactile feedback component slides to a predetermined position to trigger the button component.

[0007] In one embodiment, the screen assembly includes an outer screen and a display screen stacked sequentially from the outside to the inside, the display screen being electrically connected to the circuit board.

[0008] In one embodiment, the end of the screen bracket facing the rotating ring has a cable guide tube, which passes through the inner ring of the rotating ring and extends into the encoder. The connecting conductor of the screen assembly extends through the cable guide tube to the circuit board and is connected to a connector on the circuit board. The end of the cable guide tube away from the screen assembly is connected to the circuit board.

[0009] In one embodiment, a fastening post is formed at the bottom of the conduit, the fastening post has a fastening hole, the circuit board has a corresponding through hole, the screen assembly also includes a first connector, the through hole and the fastening post are used to pass through fasteners so that the screen bracket is connected to the circuit board.

[0010] In one embodiment, the circuit board support has a protruding fixing post on the side facing the receiving cavity, and the circuit board has a fixing hole corresponding to the fixing post. The fixing post is located in the fixing hole so that the circuit board is fixedly connected to the circuit board support.

[0011] In one embodiment, a routing bump is formed on one side of the circuit board, and an electrical connection conductor is provided on the side of the routing bump facing away from the circuit board support. The electrical connection conductor is used for electrical connection with a power source. The circuit board support has a fixing notch, and the routing bump extends to the outside of the circuit board support through the fixing notch.

[0012] In one embodiment, the base has an inclined mounting surface, the mounting hole is located on the inclined mounting surface, the bracket is correspondingly formed with a button plate, the button plate is arranged parallel to the inclined mounting surface, and the axis of the knob mechanism is at a preset angle to the horizontal plane of the bottom surface of the base.

[0015] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned headphone controller integrates the screen bracket, rotating ring, and circuit board bracket, nested layer by layer within the knob cap, forming a tactile feedback assembly. This tightly integrates the display, tactile feedback, and circuit modules along the same axis, achieving a unified design for operation and display. This not only saves panel space and reduces the overall structural complexity but also shrinks the headphone controller's size, providing favorable conditions for its miniaturization. Furthermore, the stacking of the screen components, screen bracket, and rotating ring within the knob cap compresses the axial thickness, making the headphone controller's structure more compact and lightweight.

[0016] The headphone controller drives a rotating ring to rotate synchronously via a knob cap. The rotating ring engages with the encoder's rotation trigger, triggering the encoder to generate a knob signal. This signal is processed by the circuit board and then executed according to the corresponding instruction. When pressed, the knob cap axially pushes the tactile feedback component down to the designated position, triggering a button signal to execute the corresponding instruction. The screen assembly is electrically connected to the circuit board, which transmits status information to the display screen in real time. The screen bracket and rotating ring are designed to rotate, while the screen assembly remains stationary during knob rotation, ensuring clear and visible information. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 7The headphone controller 10, as described in one embodiment of the present invention, includes a base 100, a bracket 200, a knob mechanism 300, a control component 400, and a screen component 500. The base 100 has a communicating receiving cavity 101 and a mounting hole 102. The bracket 200 is disposed within the receiving cavity 101. The knob mechanism 300 includes a knob cap 310 and a tactile feedback assembly 320. The knob cap 310 covers the mounting hole 102. The tactile feedback assembly 320 includes a screen bracket 321, a rotating ring 322, and a circuit board bracket 323, which are stacked sequentially from the outside to the inside. The tactile feedback assembly 320 passes through the mounting hole 102 and is slidably connected to the bracket 200. The circuit board bracket 323 is rotatably connected to the rotating ring 322. The rotating ring 320 is disposed within the knob cap 310 and is connected to the inner wall of the knob cap 310. The screen bracket 321 is located at the end of the rotating ring 322 that is away from the circuit board bracket 323, and the screen bracket 323 is rotatably connected to the rotating ring 322. The circuit board bracket 323 has a through hole 3231. The control component 400 includes a circuit board 410, an encoder 420, and a button component 430. The encoder 420 is located on the side of the circuit board 410 facing away from the base 100, and the button component 430 is located on the side of the circuit board 410 facing the base 100. When the tactile feedback component 320 is pressed down to a predetermined position, the button component 430 is triggered to generate a button signal. The encoder 420 passes through a through hole 3231, and a rotating ring 322 is sleeved on the outside of the encoder 420 and engages with the rotation trigger end of the encoder 420 to generate a knob signal when the rotating ring 322 rotates. The screen component 500 is disposed on the side of the screen bracket 321 facing away from the rotating ring 322 and is electrically connected to the circuit board 410.

[0023] In this embodiment, the headphone controller 10 is constructed by layering the screen bracket 321, the rotating ring 322, and the circuit board bracket 323 inside the knob cap 310 from the outside in, forming a tactile feedback assembly 320. This tightly integrates the display, tactile feedback, and circuit modules along the same axis, achieving an integrated design of operation and display. This not only saves panel space and reduces the complexity of the overall structure but also reduces the size of the headphone controller 10, providing favorable conditions for its miniaturization. Simultaneously, the stacking of the screen components 500, screen bracket 321, and rotating ring 322 within the knob cap 310 compresses the axial thickness, making the headphone controller 10 more compact and lightweight.

[0024] Specifically, the knob cap 310 drives the rotating ring 322 to rotate synchronously. The rotating ring 322 engages with the rotation trigger end of the encoder 420, triggering the encoder 420 to generate a knob signal. After processing by the circuit board 410, the corresponding instruction is executed. When pressed, the knob cap 310 axially pushes the tactile feedback component 320 down to the designated position, and the button component 430 generates a button signal to realize the corresponding instruction function. The screen assembly 500 is electrically connected to the circuit board 410. The circuit board 410 transmits status information to the screen assembly 500 in real time. The screen bracket 321 and the rotating ring 322 are rotated, and the screen assembly 500 remains stationary during the rotation of the knob cap 310, ensuring that the information is clearly visible.

[0025] It should be noted that the specific connection method between the encoder 420, circuit board 410, and tactile sensing device involved in this application is well known to those skilled in the art and can be implemented using conventional technical means. Therefore, this application does not limit this connection and will not elaborate further. The triggering method between the encoder 420 and the rotating ring 322 can be set according to the type of encoder 420: when the encoder 420 is a mechanical encoder 420, the rotating ring 322 is mechanically connected to the rotor to switch the contact signal; when the encoder 420 is a photoelectric encoder 420, the rotating ring 322 is drivenly connected to the code disk to generate a pulse signal through changes in the optical path; when the encoder 420 is a magnetic induction encoder 420, the rotating ring 322 is drivenly connected to the magnetic ring to output an electrical signal through changes in the magnetic field.

[0026] Furthermore, in one embodiment, the screen assembly 500 is attached to the side of the screen bracket 321 opposite to the mounting hole 102, and the screen bracket 321 and the screen assembly 500 are fixed together by adhesive. The screen assembly 500 and the screen bracket 321 are fixedly connected by adhesive, eliminating the need for additional fastening components. This reduces the assembly gap between the screen assembly 500 and the screen bracket 321, which helps to reduce the thickness of the tactile feedback component 320, thereby reducing the thickness of the headphone controller 10. It also simplifies the assembly process and reduces manufacturing costs.

[0027] like Figure 2 and Figure 7As shown, in one embodiment, the circuit board 410 has a first through hole 4104, and the tactile feedback component 320 has a second through hole 3201 corresponding to the first through hole 4104. The second through hole 3201 passes through the circuit board bracket 323, the rotating ring 322, and the screen bracket 321 in sequence. The bracket 200 is provided with a guide post 211 corresponding to the first through hole 4104. The tactile feedback component 320 and the circuit board 410 are sleeved on the guide post 211 through the first through hole 4104 and the second through hole 3201 and slide along the guide post 211 so that the knob mechanism 300 slides to a predetermined position to trigger the button component 430. It can be understood that the guide structure is axially arranged in the tactile feedback component 320 and the projection surface of the tactile feedback component 320 on the bracket, and the second through hole passes through each bracket, eliminating the need for additional guide structures and pressing space, simplifying the overall structure, and thus reducing the overall size of the headphone controller 10.

[0028] Furthermore, an elastic element 2111 is fitted onto the guide post 211, with both ends of the elastic element 2111 abutting against the circuit board 410 and the bracket 200, respectively. Understandably, the elastic element 2111 helps the tactile feedback component 320 to quickly reset after being pressed, ensuring consistent response and clear tactile feedback for each press operation, avoiding double-touch or delays caused by untimely reset, and improving the long-term reliability of the headphone controller 10. like Figure 2 and Figure 7 As shown, in one embodiment, the guide post 211 has a third connecting hole 2112 for a connector (not shown) to pass through, so that the haptic feedback assembly 320 can be connected to the bracket 200. This eliminates the need for an additional connecting structure, reducing the overall size of the headphone controller 10 and preventing the haptic feedback assembly 320 from detaching from the guide post 211 during use. It also simplifies the overall structure of the headphone controller 10 and improves assembly efficiency.

[0029] like Figure 4 As shown, in one embodiment, the screen assembly 500 includes an outer screen 510 and a display screen 520 arranged sequentially from the outside to the inside. The display screen 520 is electrically connected to the circuit board 410. Specifically, in this embodiment, the outer screen 510 is an OLED outer screen 510, and the display screen 520 is an OLED display screen 520. Utilizing the thinness of OLED display devices, high-definition image display is achieved while compressing the overall thickness of the screen assembly 500, further reducing the axial dimension of the overall structure. Simultaneously, the OLED outer screen 510 provides external protection for the inner display screen 520, enhancing the screen assembly 500's impact and scratch resistance, and improving its durability and reliability.

[0030] like Figures 2 to 5As shown, in one embodiment, a mounting groove 3216 is provided on the side of the screen bracket 321 facing away from the rotating ring 322. The screen assembly 500 is installed in the mounting groove 3216, which provides circumferential positioning of the screen assembly 500 and prevents it from shifting or shaking during use. Simultaneously, the mounting groove 3216 protects the sidewalls of the screen assembly 500, enhancing its lateral impact resistance and improving its structural stability and durability. Furthermore, by creating a groove on the surface of the screen bracket 321 for the screen assembly 500, the utilization rate of the internal space of the headphone controller 10 is further improved. Furthermore, such as Figure 5 As shown, a mounting flange 3217 is provided around the periphery of the mounting groove 3216. The outer screen 510 covers the mounting flange 3217 and is stacked with the display screen 520, forming a circumferential compression of the display screen 520 to prevent the display screen 520 from loosening or falling off during use. At the same time, the outer screen 510, the knob cap 310, and the mounting flange 3217 together form a multi-layer sealing structure, which can prevent external dust and liquids from seeping into the product from the edge of the knob cap 310.

[0031] like Figure 5 As shown, in one embodiment, the rotating ring 322 has a recessed groove 1011 on the side facing the screen bracket 321, and the outer peripheral wall of the screen bracket 321 is located within the recessed groove 1011. In this embodiment, the diameter of the screen bracket 321 is smaller than that of the rotating ring 322, and the outer peripheral wall of the screen bracket 321 extends into the recessed groove 1011 in the direction of the rotating ring 322. When the rotating ring 322 rotates, the recessed groove 1011 rotates around the outer peripheral wall, thereby achieving circumferential limitation and radial constraint on the screen bracket 321, preventing the screen bracket 321 from shifting during use, and thus ensuring the visibility of screen information. In addition, accommodating the outer peripheral wall of the screen bracket 321 within the recessed groove 1011 simplifies the assembly process of the haptic feedback component 320 and improves the consistency and efficiency of the headphone controller 10 assembly.

[0032] like Figures 2 to 5As shown, in one embodiment, the screen bracket 321 has a protruding cable guide 3211 on the side facing the rotating ring 322. The cable guide 3211 passes through the inner ring of the rotating ring 322 and extends into the encoder 420. The connecting conductor of the screen assembly 500 extends through the cable guide 3211 to the circuit board 410 and connects to the connector 413 on the circuit board 410. It is understood that the encoder 420 has a through cavity. The cable guide 3211 is located within the cavity, allowing the connecting conductor to be accommodated and hidden inside the encoder 420. This prevents the connecting conductor of the screen assembly 500 from being exposed in the movement path of the knob cap 310 and the rotating ring 322, preventing interference from the connecting conductor with the rotational movement of the tactile feedback assembly 320 and the knob cap 310, thus improving the space utilization and structural compactness of the tactile feedback assembly 320. Simultaneously, the cable guide 3211 prevents the connecting conductor from wearing or being stretched due to long-term rotation, thereby improving the reliability and service life of the tactile feedback assembly 320.

[0033] Furthermore, such as Figure 2 and Figure 5 As shown, in this embodiment, a cable routing groove 3212 is provided on the side of the screen bracket 321 facing away from the rotating ring 322, and the cable routing groove 3212 is connected to the cable guide tube 3211. Specifically, by providing the cable routing groove 3212 connected to the cable guide tube 3211, the screen bracket 321 houses the connecting conductor at the edge of the screen assembly 500 within the cable routing groove 3212, preventing the connecting conductor from protruding outwards, further reducing the gap between the screen assembly 500 and the screen bracket 321, and reducing the thickness of the tactile feedback component 320. In addition, the cable routing groove 3212 and the cable guide tube 3211 form a unique wiring path, which plays a foolproof role during assembly, ensuring the accurate installation orientation of the screen assembly 500 and improving the assembly efficiency of the headphone controller 10.

[0034] like Figures 2 to 5 As shown, in this embodiment, a fastening post 3213 is formed at the bottom of the cable guide tube 3211, and the fastening post 3213 has a fastening hole 3214. The circuit board 410 has a corresponding through hole 4101. The through hole 4101 and the fastening post 3213 are used to pass through fasteners (not shown) to connect the screen bracket 321 to the circuit board 410. The screen assembly 500 also includes fasteners, which are sequentially passed through the through hole 4101 and the fastening hole 3214 to fix the screen bracket 321 to the circuit board 410. This ensures that the screen assembly 500 remains stationary when the knob cap 310 is rotated, ensuring that the screen information is visible, and preventing the screen bracket 321 from shifting or deflecting during use. Specifically, the fastening post 3213 protrudes axially inside the cable guide tube 3211, making full use of the internal space of the cable guide tube 3211, making the overall layout more regular, improving the space utilization and structural compactness of the tactile feedback assembly 320, which is beneficial for simplifying assembly and reducing external interference.

[0035] Furthermore, such as Figures 2 to 5 As shown, in one embodiment, two positioning posts 3215 protrude from the bottom of the cable guide 3211 and are diagonally arranged. The circuit board 410 has positioning holes 4102. The two positioning posts 3215 are inserted into the two positioning holes 4102 one by one to fix the screen bracket 321 to the circuit board 410. It can be understood that the two diagonally arranged positioning posts 3215 are respectively inserted into the corresponding positioning holes 4102, thereby improving the stability of the connection between the screen bracket 321 and the circuit board 410, and further ensuring that the screen assembly 500 remains stationary when the knob cap 310 is rotated. At the same time, the positioning posts 3215 protruding from the bottom of the cable guide 3211 are directly inserted into the positioning holes 4102 of the circuit board 410, eliminating the need for additional fasteners and simplifying the structure and assembly steps of the tactile feedback assembly 320.

[0036] like Figures 2 to 5 As shown, in one embodiment, a fixing post 3232 protrudes from the side of the circuit board bracket 323 facing away from the rotating ring 322. A fixing hole 4103 is formed on the circuit board 410 corresponding to the fixing post 3232, and the fixing post 3232 is located within the fixing hole 4103 to fix the circuit board 410 to the circuit board bracket 323. Specifically, in this embodiment, the fixing post 3232 is a thermoplastic post. The end of the thermoplastic post softens and deforms after heating to form a rivet head, locking the circuit board 410 onto the circuit board bracket 323. Thus, the control component 400 does not require additional fasteners (not shown), which not only simplifies the assembly steps of the headphone controller 10 and reduces manufacturing costs but also provides good shock resistance. Simultaneously, it makes the overall haptic feedback component 320 more compact, saving internal space and facilitating the miniaturization of the headphone controller 10.

[0037] Furthermore, such as Figure 4 and Figure 5 As shown, in one embodiment, a fixing groove 3233 is provided on the side of the circuit board bracket 323 facing away from the rotating ring 322. The fixing groove 3233 communicates with the through hole 3231. The circuit board 410 is disposed in the fixing groove 3233, thereby limiting the circumferential movement of the circuit board 410 and preventing it from shifting or vibrating during use. Simultaneously, the fixing groove 3233 protects the sidewalls of the circuit board 410, enhancing its lateral impact resistance and improving its durability and the safety of the headphone controller. Furthermore, by creating a groove on the surface of the circuit board bracket 323 to house the circuit board 410, the utilization rate of the internal space of the headphone controller 10 is further improved.

[0038] like Figure 4 and Figure 5As shown, in one embodiment, the side of the circuit board bracket 323 facing the rotating ring 322 has an abutment flange 3235, and the end of the abutment flange 3235 away from the circuit board bracket 323 abuts against the bottom of the rotating ring 322. It can be understood that by abutting against the bottom of the rotating ring 322 with the abutment flange 3235, the circuit board bracket 323 can stably support the rotating ring 322, prevent axial movement of the rotating ring 322, and reduce frictional resistance, ensuring smoother rotation of the rotating ring 322 and improving the user experience. At the same time, directly molding the support structure onto the fixed circuit board bracket 323 eliminates the need for additional bearings or washers, saving internal space and facilitating the miniaturization and integration of the headphone controller 10.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, a routing protrusion 411 is formed on the side of the circuit board 410 facing away from the circuit board bracket 323. An electrical connection conductor 4111 is provided on the side of the routing protrusion 411 facing away from the circuit board bracket 323. The electrical connection conductor 4111 is used for electrical connection with the power supply. The circuit board bracket 323 has a fixing notch 3234. The routing protrusion 411 extends to the outside of the circuit board bracket 323 through the fixing notch 3234, making full use of the space between the bracket 200 and the circuit board 410, so that the electrical connection conductor 4111 is arranged in a regular manner, avoiding interference or compression caused by the electrical connection conductor 4111 being suspended, thereby improving the reliability and safety of the electrical connection. At the same time, the fixing notch 3234 forms a circumferential limit on the circuit board 410, preventing the circuit board 410 from rotating or shifting during assembly or use, ensuring the stability of the electrical connection and the consistency of assembly. In addition, the cooperation between the routing bump 411 and the fixing notch 3234 ensures that the installation direction of the circuit board 410 is unique, which plays a role in preventing mistakes during the assembly process, avoiding incorrect installation of the circuit board 410, and improving assembly efficiency.

[0040] Furthermore, such as Figure 6 As shown, a clearance groove 1011 is formed on the inner wall of the receiving cavity 101 corresponding to the wiring protrusion 411. The circuit board 410 is located inside the receiving cavity 101, and the wiring protrusion 411 is located inside the clearance groove 1011. Specifically, in this embodiment, the contour of the clearance groove 1011 is adapted to the wiring protrusion 411, which can not only avoid interference between the wiring protrusion 411 and the inner wall of the base 100, but also provide a clear installation direction and improve assembly efficiency.

[0041] Furthermore, such as Figure 2As shown, a wiring hole 201 is provided at the bottom of the side of the bracket 200 facing the circuit board 410. The electrical connection conductor 4111 of the circuit board 410 extends into the bracket 200 through the wiring hole 201 to connect the circuit board 410 to the power supply. It can be understood that the wiring hole 201 provides a unique routing path for the electrical connection conductor 4111 of the circuit board 410, improving the reliability of the electrical connection and the consistency of the product.

[0042] like Figure 5 As shown, in one embodiment, an annular groove 311 is formed at one end of the knob cap 310 near the base 100. A locking block 312 protrudes from the inner wall of the annular groove 311, and a locking notch 3222 is provided for the rotating ring 322. The rotating ring 322 is disposed in the annular groove 311 and is circumferentially fixed by the locking block 312 and the locking notch 3222, so that the rotational torque of the knob cap 310 can be synchronously transmitted to the rotating ring 322, avoiding slippage or free rotation, and improving the operating feel and transmission reliability. At the same time, the rotating ring 322 is completely accommodated in the knob cap 310, which not only makes the overall structure more compact, but also reduces the risk of foreign objects getting stuck. Specifically, in this embodiment, there are two locking blocks 312 and two locking notches 3222. The two locking blocks 312 are symmetrically arranged on the inner wall of the annular groove 311, which makes the knob cap 310 more evenly stressed. This can further improve the stability and concentricity of torque transmission, avoid swaying or jamming caused by unilateral stress, and thus improve the smoothness and consistency of knob operation.

[0043] Furthermore, such as Figure 3 and Figure 4 As shown, the annular groove 311 has multiple abutment protrusions 3111 spaced apart at one end near the base 100. When the rotating ring 322 is installed in the annular groove 311, the bottom surface of the rotating ring 322 abuts against the abutment protrusions 3111, thereby confining the rotating ring 322 inside the knob cap 310. That is, the rotating ring 322 is completely housed within the contour of the knob cap 310, making the overall structure of the knob mechanism 300 more compact, reducing the risk of foreign objects getting stuck, and facilitating manufacturing and demolding. At the same time, the abutment protrusions 3111 provide support and limit, reducing the friction area of ​​the rotating ring 322 during rotation, making the rotation smoother, reducing wear, and extending the service life of the tactile feedback component 320. In this embodiment, preferably, four abutment protrusions 3111 are evenly spaced apart to form a stable support plane.

[0044] like Figure 1As shown, in one embodiment, the outer peripheral wall of the knob cap 310 is provided with anti-slip texture 313. Specifically, in this embodiment, the anti-slip texture 313 is a knurled pattern. By providing the anti-slip texture 313 on the outer peripheral wall of the knob cap 310, the contact friction between the knob cap 310 and the user's fingers can be increased, effectively preventing slippage caused by sweaty hands or improper force application, thereby improving the accuracy and smoothness of the rotation operation. It should be noted that the specific shape of the anti-slip texture 313 is not limited to the knurling pattern used in this embodiment. In other embodiments, it can also be set as a straight line, a mesh pattern, or other texture structure that can achieve the anti-slip function.

[0045] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment, the base 100 has an inclined mounting surface 110, and the mounting hole 102 is opened on the inclined mounting surface 110. The bracket 200 is correspondingly formed with a button plate 210, which is arranged parallel to the inclined mounting surface 110. The axis of the knob mechanism 300 is at a preset angle to the vertical direction.

[0046] Specifically, in this embodiment, the angle between the inclined mounting surface 110 and the bottom horizontal plane of the base 100 is 70°, and the angle between the axis of the knob mechanism 300 and the bottom horizontal plane of the base 100 is 160°. That is, the tilt angle of the axis of the knob mechanism 300 relative to the horizontal plane is 20°. Users can clearly read the scale or screen information on the knob mechanism 300 without bending down or changing their sitting posture, improving the comfort of use. At the same time, the 70° mounting slope and the 160° axis angle work together to make the rear volume of the knob mechanism 300 extend obliquely, improving space utilization and facilitating the miniaturization of the headphone controller 10. In addition, the tilt angle of the button plate 210 is consistent with that of the inclined mounting surface 110, which can avoid the angular deviation causing the tactile generator to jam or wobble during use, thereby improving the assembly consistency and long-term reliability of the headphone controller 10. At the same time, the angle space between the bracket 200 and the inclined mounting surface 110 can be fully utilized, which helps to improve space utilization and reduce the overall size of the headphone controller 10. In addition, the button panel 210 is isolated from the bracket 200 to prevent interference between the tactile generator and other components of the bracket 200 during assembly or use.

[0047] like Figure 2 and Figure 7As shown, in one embodiment, the keypad 210 is provided with a first limiting post 212 corresponding to the key component 430. When the tactile feedback component 320 is pressed down along the guide post 211 to a predetermined position, the key component 430 abuts against the first limiting post 212, triggering a key signal through the abutting action to realize the key function. Specifically, in this embodiment, the circuit board 410 moves synchronously with the tactile feedback component 320, and the first limiting post 212 is provided on the keypad 210 and extends towards the circuit board 410. The key component 430 moves with the tactile feedback component 320 and abuts against the first limiting post 212 on the keypad 210, achieving triggering without the need for an additional transmission structure, simplifying the assembly steps. The first limiting post 212 provides a stable fulcrum for the key component 430, realizing physical limitation of the pressing depth of the knob mechanism 300, ensuring that the key component 430 is triggered at the same position each time it is pressed, improving the consistency and reliability of the key response. At the same time, it avoids damage to the circuit board 410 or the tactile feedback component 320 caused by excessive pressing, improves the durability of the tactile feedback component 320, and thus extends the service life of the headphone controller 10.

[0048] It should be noted that the specific triggering method between the button component 430, the circuit board 410, and the tactile feedback component 320 involved in this application is known to those skilled in the art and can be implemented using conventional technical means. Therefore, this application does not limit this method and will not elaborate further.

[0049] Meanwhile, the triggering method of the button components is not limited to contact with the limiting post. In other embodiments, the limiting post can be omitted, and button triggering can be achieved through magnetic, optical, or electrical coupling. For example, a Hall switch can be triggered by the change in the magnetic field between the magnet on the tactile sensing component and the bracket; a signal can be triggered by the change in the optical path between the light-shielding part and the photoelectric sensor; or a sensing electrode can be triggered by the capacitive coupling between the conductive part and the bracket. The above-mentioned non-contact triggering methods do not require physical contact, which can simplify the structure, avoid mechanical wear, and improve service life and reliability.

[0050] like Figure 2 As shown, in one embodiment, an annular flange 1021 is formed at the end of the mounting hole 102 opposite to the receiving cavity 101, and the annular flange 1021 is located inside the knob cap 310. The diameter of the mounting hole 102 is smaller than the diameter of the knob cap 310 to limit the excessive movement of the knob cap 310 along the axial direction of the receiving cavity 101, and to prevent the knob from being pressed into the receiving cavity 101 and causing compression to the circuit board 410. At the same time, the annular flange 1021 provides circumferential limiting and support for the circuit board bracket 323, preventing the circuit board bracket 323 from shifting during assembly or use.

[0051] like Figure 2 , Figure 6 and Figure 7As shown, in one embodiment, the end of the bracket 200 away from the button plate 210 has a first connecting hole 202, and the end of the base 100 away from the mounting hole 102 has a connecting post 120 corresponding to the first connecting hole 202. The first connecting hole 202 and the second connecting hole 102 are used to pass through a connector (not shown) to fix the base 100 and the bracket 200 together. Specifically, in this embodiment, there are four first connecting holes 202 and four connecting posts 120. The four first connecting holes 202 are located at the four corners of the bracket 200, and the four connecting posts 120 are correspondingly arranged with the four first connecting holes 202. The four-corner distribution structure can constrain the bracket 200 and prevent it from shifting or twisting during assembly and use, thereby improving the stability of the connection. At the same time, the uniform layout of the connection points can avoid stress concentration, ensure the accurate assembly position of the bracket 200, and prevent the bracket 200 from bending or deforming due to stress.

[0052] Furthermore, such as Figure 2 , Figure 6 and Figure 7 As shown, a guide block 1012 is formed on the inner wall of the receiving cavity 101, and a guide groove 203 is correspondingly provided on the bracket 200. The guide block 1012 is located within the guide groove 203. Through the sliding engagement between the guide block 1012 and the guide groove 203, it plays a guiding role during the assembly of the bracket 200, thereby improving the assembly positional accuracy of the bracket 200. Specifically, there are three guide blocks 1012, which are respectively set on three different surfaces of the inner wall of the receiving cavity 101. The bracket 200 has three corresponding guide grooves 203, and the three guide grooves 203 correspond one-to-one with the three guide blocks 1012. During assembly, the guide blocks 1012 and the guide grooves 203 simultaneously form a fit on three sides, which can limit the bracket 200 from multiple directions, preventing the bracket 200 from shifting or shaking during assembly or use, thereby further improving the stability and positional accuracy of the installation.

[0053] Furthermore, such as Figure 2 and Figure 6 As shown, the receiving cavity 101 has an abutment block 1013 formed at one end where the mounting hole 102 is provided. The abutment block 1013 abuts against the bracket 200 to limit the insertion depth of the bracket 200, ensuring that the bracket 200 can accurately stop at the predetermined position during assembly, and avoiding collision or compression between the bracket 200 and other components such as the circuit board 410 or the tactile sensing component 320. At the same time, it ensures the consistency of the assembly depth of the bracket 200, improving the consistency and yield rate of the headphone controller 10.

[0054] like Figure 2 and Figure 7As shown, in one embodiment, the bracket 200 also has a placement slot 204 for accommodating the functional component 600. Specifically, the functional component 600 includes, but is not limited to, at least one of a battery, a main control circuit module, or a counterweight. By accommodating the functional component within the placement slot 204 of the bracket 200, there is no need to provide separate mounting structures for each functional component 600, simplifying the overall structure of the headphone controller 10 and reducing its overall size. When a mounting block is placed within the placement slot 204, the counterweight increases the overall mass of the bracket 200, balancing the weight of the knob mechanism 300 and the torque generated during operation, preventing the hollow bracket 200 from tipping over or tilting under stress, thus improving the stability and reliability of the headphone controller 10. Simultaneously, the functional component being installed inside the bracket 200 helps to shorten the electrical connection distance between components, reduce the space required for wiring harnesses, and further improve space utilization.

[0055] Furthermore, such as Figure 2 and Figure 7 The bottom of the placement slot 204 is provided with a second limiting post 2041, and the functional element 600 has a corresponding limiting hole. The second limiting post 2041 passes through the limiting hole to fix the installation position of the functional element 600 on the bracket 200. This can prevent the functional element from shifting or even falling off during transportation and use, thereby improving the structural stability and long-term reliability of the headphone controller 10.

[0056] Furthermore, the bracket 200 has a wiring structure and a fixing structure corresponding to the connection lines of the headphone controller 10, which are used to attach and position the lines of the headphone controller 10 on the surface of the bracket 200. This simplifies the wiring structure and helps to reduce the overall size of the headphone controller 10. At the same time, it improves the assembly efficiency and electrical safety of the headphone controller 10.

[0057] This disclosure also provides a headset, which includes a headset body and a headset controller 10 as described in any of the above embodiments. The headset body is electrically connected to the headset controller 10, and the headset controller 10 is used to drive and control the audio output of the headset body.

[0058] Specifically, in this embodiment, the headphone controller 10 establishes a communication connection with the headphone body via Bluetooth. The headphone controller 10 receives audio signals from the audio source device, processes them, and wirelessly transmits them to the headphone body via Bluetooth for playback by the headphone body's speaker unit. It is understood that the headphone body and headphone controller 10 are electrically connected wirelessly, allowing for separate installation of the headphone body and headphone controller 10. This not only reduces the weight and complexity of the headphone body but also provides users with more flexible device placement and usage methods.

[0059] It should be noted that the specific circuit structure and communication protocol of the wireless communication module are existing technologies known in the art. Those skilled in the art can implement them based on the description in this disclosure and common knowledge, and will not be elaborated here.

[0060] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned headphone controller integrates the screen bracket, rotating ring, and circuit board bracket, nested layer by layer within the knob cap, forming a tactile feedback assembly. This tightly integrates the display, tactile feedback, and circuit modules along the same axis, achieving a unified design for operation and display. This not only saves panel space and reduces the overall structural complexity but also shrinks the headphone controller's size, providing favorable conditions for its miniaturization. Furthermore, the stacking of the screen components, screen bracket, and rotating ring within the knob cap's internal space compresses the axial thickness, making the headphone controller's structure more compact and lightweight.

[0061] The headphone controller drives a rotating ring to rotate synchronously via a knob cap. The rotating ring engages with the encoder's rotation trigger, triggering the encoder to generate a knob signal. This signal is processed by the circuit board and then executed according to the corresponding instruction. When pressed, the knob cap axially pushes the tactile feedback component to a designated position, triggering a button signal to execute the corresponding instruction. The screen assembly is electrically connected to the circuit board, which transmits status information to the display screen in real time. The screen bracket and rotating ring are designed to rotate, while the screen assembly remains stationary during knob rotation, ensuring clear and visible information.

[0062] 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.
