[0050] This invention proposes an earphone case.

[0051] In embodiments of the present invention, such as Figures 1 to 4 As shown, the earphone case includes a housing 100, two earphone holders 200, a knob 300, and a transmission structure.

[0052] Two headphone holders 200 are movably mounted on the housing 100 for holding headphones; a knob 300 is movably disposed in the housing 100 and is at least partially exposed on the surface of the housing 100; a transmission structure is disposed inside the housing 100 and drives the knob 300 and the two headphone holders 200; the knob 300 can rotate under the action of external force, driving the transmission structure to drive at least one headphone holder 200 to move relative to the housing 100 to extend or retract into the housing 100.

[0053] In this embodiment, the housing 100 serves to support and fix components such as the earphone holder 200, knob 300, transmission structure, charging module, cleaning module, or other functional modules of the earphone case. The earphone holder 200 is used to hold the earphones and can extend out of or retract into the housing 100 relative to it, thus facilitating the taking and placing of the earphones. The knob 300 is movably mounted on the housing 100 and acts as a trigger switch. The transmission structure connects the knob 300 and the earphone holder 200, transmitting power from the knob 300 to the earphone holder 200. This allows the user to easily move the earphone holder 200 out of or retract into the housing 100 simply by rotating the knob 300, improving user convenience and ease of use.

[0054] Understandably, the shape and structure of the housing 100 in this embodiment can be determined according to actual conditions, such as being cylindrical, rectangular, square, or other irregular shapes. The shape and structure of the knob 300 can also be determined according to actual conditions, such as being a cylindrical handle structure, a lever structure, or other structures, as long as it facilitates user rotation. The shape and structure of the headphone holder 200 can also be determined according to actual conditions, as long as it can hold headphones and can be slidably connected to the housing 100. The headphone holder 200 is slidably and rotatably connected to the housing, and can extend or retract from the side of the housing 100, or it can extend or retract from the top or bottom of the housing 100. Considering user habits and factors such as preventing drops, as an example, the headphone holder 200 is installed on the side of the housing 100 and extends or retracts from the side of the housing 100 to prevent the headphones from falling out.

[0055] The transmission structure connects the knob 300 and the headphone jack 200. The specific structure of the transmission structure can be determined according to actual conditions, such as a gear transmission structure, a wedge block transmission structure, an electronically controlled transmission structure, or a linkage transmission structure, etc. The specific structure is not limited here. The two headphone jacks 200 are connected to the knob 300 through the transmission structure. The user can rotate the knob 300 to move one headphone jack 200 out of the housing 100, or simultaneously move both headphone jacks 200 out of the housing 100. The user can choose to use one or two headphones according to their needs.

[0056] In the headphone case of this invention, two headphone holders 200 are movably connected to the housing 100, and a knob 300 is movably connected to the housing 100. By setting a transmission structure inside the housing 100, the knob 300 and the two headphone holders 200 are connected, so that the user only needs to turn the knob 300 to drive at least one headphone holder 200 to move out of the housing 100 or move out of the housing 100 and retract into the housing 100, which makes it easier for the user to take out and put away the headphones and improves the user's operational convenience.

[0057] In one embodiment of this application, please refer to Figures 2 to 4 Two earphone holders 200 are respectively located at opposite ends of the housing 100, and a knob 300 is located between the two earphone holders 200 and is partially exposed outside the housing 100. The knob 300 can rotate under the action of external force, driving the transmission structure to move one earphone holder 200 away from or closer to the other earphone holder 200 so as to extend or retract into the housing 100.

[0058] Understandably, each headphone holder 200 is used to hold one headphone. With two headphone holders 200 respectively set at opposite ends of the housing 100, the two headphone holders 200 can be moved out or retracted from both ends of the housing 100 by rotating the knob 300, so that the headphone holders 200 can move in the horizontal plane. This design can prevent the headphone from falling out during the movement of the headphone holders 200, and improve the reliability of the headphone retrieval process.

[0059] In this embodiment, the knob 300 is positioned between the two headphone jacks 200 and partially exposed outside the housing 100, making it easier for the user to operate. Furthermore, positioning the knob 300 between the two headphone jacks 200 simplifies the transmission structure between the knob 300 and the two headphone jacks 200, enabling the movement of both headphone jacks 200 to be controlled by a single knob 300.

[0060] As an example, please refer to Figures 2 to 4 The knob 300 and the headphone holder 200 can be placed on different surfaces of the housing 100. For example, the knob 300 can be placed on the top surface of the housing 100, and the headphone holder 200 can be placed on both sides of the housing 100. This arrangement can prevent interference between the movement of the knob 300 and the headphone holder 200, and can also simplify the layout of the transmission structure. In addition, placing the knob 300 on the top surface of the housing 100 is more in line with the user's usage habits and facilitates one-handed operation.

[0061] Further, please refer to Figure 3 and Figure 4 The housing 100 is provided with an installation port 101 and a positioning post 102. The knob 300 is sleeved on the positioning post 102 and passes through the installation port 101. The knob 300 can move along the axial direction of the positioning post 102. The part of the knob 300 located inside the housing 100 is provided with a toothed structure 301.

[0062] This embodiment illustrates the mounting structure of the knob 300 and the housing 100. The mounting opening 101 allows the knob 300 to pass through, so that part of the knob 300 is exposed outside the housing 100 for easy user operation. The positioning post 102 supports the mounting of the knob 300. The knob 300 is fitted onto the positioning post 102 and can rotate along the positioning post 102 and also move along the axial direction of the positioning post 102. It can be understood that the knob 300 can both rotate and move relative to the housing 100. The purpose of the knob 300 moving along the positioning post 102 is to select one or two headphone jacks 200 corresponding to the transmission structure. After selection, rotating the knob 300 drives the transmission structure to extend or retract the corresponding headphone jack 200 from or into the housing 100. This design allows users to select the desired headphones according to their needs, meeting different usage requirements and improving the user experience.

[0063] As an example, please refer to Figure 2 The part of the knob 300 extending out of the housing 100 is provided with an operating protrusion 302, and the housing 100 is provided with a first limiting member 104 for limiting the operating protrusion 302.

[0064] By providing an operating protrusion 302 on the part of the knob 300 exposed outside the housing 100, user operation is made easier. Simultaneously, a first limiting member 104 is provided on the housing 100 to limit the operating protrusion 302, preventing it from entering the mounting opening 101, and also limiting the rotational stroke of the toothed structure 301, thus limiting the opening and closing position of the earphone holder 200. Optionally, the first limiting member 104 is located on one side of the mounting opening 101.

[0065] Further, please refer to Figures 2 to 4 The tooth structure 301 is only provided on part of the outline of the knob 300. During the rotation of the knob 300, it can avoid interference between the tooth structure 301 and the mounting port 101 of the housing 100, and ensure the reliability of the fit between the mounting port 101 and the knob 300.

[0066] In one embodiment of this application, the housing 100 includes an upper housing 110 and a bottom housing 120. The upper housing 110 covers the bottom housing 120, two earphone sockets 200 are disposed on the bottom housing 120, and a knob 300 is disposed on the upper housing 110.

[0067] Understandably, the upper shell 110 and the lower shell 120 form a receiving space to accommodate the earphone holder 200 and transmission components, etc. In this embodiment, the shell 100 is designed as a split structure, which facilitates disassembly and assembly, as well as the installation and maintenance of internal components. Optionally, the lower shell 120 and the upper shell 110 can be fixed by adhesive bonding. The two earphone holders 200 are respectively located on opposite sides of the lower shell 120, and the knob 300 is located on the upper shell 110.

[0068] To ensure the cleanliness of the inside of the earphone case, please refer to [link / reference needed]. Figures 1 to 4 The earphone case also includes a dust cover 600 that covers the upper shell 110, and the dust cover 600 is snapped into the upper shell 110. It is understood that the upper shell 110 has a mounting opening 101 for the knob 300 to pass through, so external dust, impurities, and other particles may enter the interior of the shell through the mounting opening 101. Therefore, in this embodiment, a dust cover 600 is installed on the upper shell 110 to provide dust protection. At the same time, the dust cover 600 is snapped into the upper shell 110 for easy installation and removal, thus facilitating user operation of the knob 300.

[0069] In one embodiment of this application, please refer to Figures 3 to 8The transmission structure is a gear transmission structure. The knob 300 is provided with a tooth structure 301 that meshes with the gear transmission structure, and the earphone holder 200 is provided with a rack (200a / 200b) that meshes with the gear transmission structure.

[0070] This embodiment illustrates the specific structure of the transmission structure, which is a gear transmission structure. It can be understood that the connection between the transmission structure, the knob 300, and the earphone holder 200 is a gear meshing connection, achieving the transmission function between the knob 300 and the earphone holder 200 through a purely mechanical structure. Specifically, the knob 300 has a toothed structure 301, and one end of the earphone holder 200 has a rack. The knob 300 is meshed with the gear transmission structure through the toothed structure 301, so that rotating the knob 300 can drive the gear transmission structure to move, and the gear transmission structure can drive the rack to move, causing the earphone holder 200 to extend or retract into the housing 100.

[0071] In practical applications, the gear transmission structure can be a single-stage, two-stage, or multi-stage transmission, depending on the internal space of the housing 100 and / or the positional relationship between the knob 300 and the headphone holder 200. For example, if the rotation direction of the knob 300 is the same as the movement direction of the headphone holder 200, the gear transmission structure does not need to reverse direction, and a single-stage transmission can be used. If the rotation direction of the knob 300 is different from the movement direction of the headphone holder 200, the gear transmission structure needs to have a reversing function, and in this case, a two-stage or multi-stage transmission can be used. The specific gear transmission structure is not limited here.

[0072] It should be noted that gear transmission structures are not limited to a specific type of gear structure; they can include spur gears, helical gears, bevel gears, worm gears, or other structures with teeth.

[0073] As an example, please refer to Figures 3 to 4 In this embodiment, considering that one knob 300 controls two earphone jacks 200, the racks of the two earphone jacks 200 are defined as the first rack 200a and the second rack 200b (as shown in the figure, the earphone jack on the left is provided with the first rack, and the earphone jack on the right is provided with the second rack); the gear transmission structure includes a first transmission component 410 and a second transmission component 420. The first transmission component 410 is used to drive the gear structure 301 and the first rack 200a, and the second transmission component 420 is used to drive the gear structure 301 and the second rack 200a; the knob 300 can move relative to the housing 100 to drive the gear structure 301 to mesh with at least one of the first transmission component 410 and the second transmission component 420.

[0074] In this embodiment, the transmission assembly includes a first transmission assembly 410 and a second transmission assembly 420 for driving the two earphone holders 200 respectively. The first transmission assembly 410 connects the toothed structure 301 to the first rack 200a, and the second transmission assembly 420 connects the toothed structure 301 to the second rack 200a. This arrangement allows the two earphone holders 200 to move independently or simultaneously. In practical applications, when the user only needs to use one earphone, the knob 300 can be moved along the positioning post 102 to a position where its toothed structure 301 engages with either the first transmission assembly 410 or the second transmission assembly 420, and then the knob 300 can be rotated to drive the corresponding earphone holder 200 to extend. When the user needs to use two earphones simultaneously, the knob 300 can be moved along the positioning post 102 to a position where its toothed structure 301 engages with both the first transmission assembly 410 and the second transmission assembly 420, and then the knob 300 can be rotated to drive both earphone holders 200 to extend from the housing 100.

[0075] Specifically, please refer to Figures 3 to 8 The first transmission assembly 410 includes a first gear shaft 411, a first reversing assembly 412, a first rotating shaft 413, and a first gear 414 disposed on the first rotating shaft 413. The first gear 414 is meshed with a first rack 200a, and the first reversing assembly 412 is drivingly connected to the first gear shaft 411 and the first rotating shaft 413. The second transmission assembly 420 includes a second gear shaft 421, a second reversing assembly 422, a second rotating shaft 423, and a second gear 424 disposed on the second rotating shaft 423. The second gear 424 is meshed with a second rack 200b, and the second reversing assembly 422 is drivingly connected to the second gear shaft 421 and the second rotating shaft 423. The tooth structure 301 is meshed with the first gear shaft 411 and / or the second gear shaft 421.

[0076] This embodiment illustrates the specific structure of the first transmission component 410 and the second transmission component 420. The knob 300 can move relative to the housing 100 to drive the tooth structure 301 to mesh with at least one of the first gear shaft 411 and the second gear shaft 421.

[0077] Please see Figure 5 and Figure 6 When the tooth structure 301 meshes with the first gear shaft 411, rotating the knob 300 causes the tooth structure 301 to drive the first gear shaft 411 to rotate, which in turn drives the first rotating shaft 413 to rotate via the first reversing component 412. This, in turn, causes the first gear 414 to rotate around the first rotating shaft 413, and then drives the first rack 200a to move, thereby realizing the function of driving the corresponding headphone holder 200 (as shown in the figure, the left headphone holder) to move out or be stored in the housing 100.

[0078] Please see Figure 7and Figure 8 When the tooth structure 301 meshes with the second gear shaft 421, rotating the knob 300 causes the tooth structure 301 to drive the second gear shaft 421 to rotate. This drives the second rotating shaft 423 to rotate via the second reversing assembly 422, which in turn drives the second gear 424 to rotate around the first rotating shaft 423. This then drives the second rack 200b to move, thereby enabling the corresponding headphone holder 200 (as shown in the right headphone holder in the figure) to move out or be stored in the housing 100.

[0079] Please see Figure 3 and Figure 4 When the tooth structure 301 meshes with the first gear shaft 411 and the second gear shaft 421 simultaneously, rotating the knob 300 can simultaneously drive the two headphone jacks 200 to move out or be stored in the housing 100.

[0080] In one embodiment, please refer to Figure 3 and Figure 4 The first gear shaft 411 and the second gear shaft 421 are coaxially arranged, and the gears of the first gear shaft 411 and the second gear shaft 421 are spaced apart in the axial direction. The ends of the first gear shaft 411 and the second gear shaft 421 are rotatably connected. The movement direction of the knob 300 relative to the housing 100 is parallel to the axial direction of the first gear shaft 411.

[0081] In this embodiment, by coaxially arranging the first gear shaft 411 and the second gear shaft 421 and setting the gear spacing of the two gear shafts relative to each other, the knob 300 can be moved axially to drive its tooth structure 301 to mesh with the first gear shaft 411 alone, or with the second gear shaft 421 alone, or with both the first gear shaft 411 and the second gear shaft 421. Simultaneously, by rotatably connecting the ends of the first gear shaft 411 and the second gear shaft 421, when the knob 300 drives one of the first gear shaft 411 and the second gear shaft 421, the other remains fixed without being driven. This allows for the extension or retraction of only one earphone holder 200, improving the user experience.

[0082] Optionally, the ends of the first gear shaft 411 and the second gear shaft 421 can be connected by a shaft hole fit to realize the function of relative rotation between the two.

[0083] Furthermore, based on the aforementioned embodiment where the knob 300 is sleeved on the positioning post 102, the axial direction of the positioning post 102 is parallel to the axial direction of the first gear shaft 411, so that the knob 300 can move and switch between positions meshing with the two gear shafts.

[0084] As an example, the rotation axis of the first gear shaft 411 is perpendicular to the rotation axis of the first rotating shaft 413. The rotation axis of the second gear shaft 421 is perpendicular to the rotation axis of the second rotating shaft 423.

[0085] In one embodiment of this application, please refer to Figure 3 and Figure 4 The first reversing assembly 412 includes a first bevel gear 4121 and a second bevel gear 4122 that are meshed together. The first bevel gear 4121 is mounted on the first gear shaft 411, and the second bevel gear 4122 is mounted on the first rotating shaft 413.

[0086] This embodiment illustrates the specific structure of the first reversing assembly 412. Through the meshing connection of the first bevel gear 4121 and the second bevel gear 4122, both reversing and power transmission functions are achieved. It can be understood that the rotation axis of the first bevel gear 4121 and the rotation axis of the second bevel gear 4122 are set at an angle. The rotation axis of the first bevel gear 4121 is aligned with that of the first gear shaft 411, and the rotation axis of the second bevel gear 4122 is aligned with that of the first rotating shaft 413.

[0087] In practical applications, when the user rotates the knob 300, the gear structure 301 drives the first gear shaft 411 to rotate, which in turn drives the first bevel gear 4121 mounted on the first gear shaft 411 to rotate, which in turn drives the second bevel gear 4122 to drive the first rotating shaft 413 to rotate, which in turn drives the first gear 414 mounted on the first rotating shaft 413 to rotate, thereby driving the first rack 200a to move, so that the corresponding headphone holder 200 (as shown in the figure, the left headphone holder) can move to extend or retract into the housing 100.

[0088] Accordingly, in one embodiment of this application, please refer to Figure 3 and Figure 4 The second reversing assembly 422 includes a third bevel gear 4221 and a fourth bevel gear 4222 that are meshed together. The third bevel gear 4221 is mounted on the second gear shaft 421, and the fourth bevel gear 4222 is mounted on the second rotating shaft 423.

[0089] This embodiment illustrates the specific structure of the second reversing assembly 422. Through the meshing connection of the third bevel gear 4221 and the fourth bevel gear 4222, both reversing and power transmission functions are achieved. It is understood that the rotation axis of the third bevel gear 4221 and the rotation axis of the fourth bevel gear 4222 are set at an angle. The rotation axis of the third bevel gear 4221 is aligned with that of the second gear shaft 421, and the rotation axis of the fourth bevel gear 4222 is aligned with that of the second rotating shaft 423.

[0090] In practical applications, when the user rotates the knob 300, the gear structure 301 drives the second gear shaft 421 to rotate, which in turn drives the third bevel gear 4221 mounted on the second gear shaft 421 to rotate, which in turn drives the fourth bevel gear 4222 to drive the second rotating shaft 423 to rotate, which in turn drives the second gear 424 mounted on the second rotating shaft 423 to rotate, thereby driving the second rack 200b to move, so that the corresponding headphone holder 200 (as shown in the figure on the right) can move out or retract into the housing 100.

[0091] For further details, please refer to Figure 3 and Figure 4 Two first gears 414 can be installed on the first rotating shaft 413, with the two first gears 414 located on both sides of the second bevel gear 4122. Correspondingly, two first racks 200a can be installed, which mesh with the two first gears 414 respectively. This can enhance the stability of driving the left earphone holder 200 to move. Optionally, the two first racks 200a are spaced apart on one side of the left earphone holder 200 to ensure the smooth movement of the left earphone holder 200 and prevent the left earphone holder 200 from tilting or even jamming due to uneven force.

[0092] Accordingly, please refer to Figure 3 and Figure 4 Two second gears 424 can be installed on the second rotating shaft 423, with the two second gears 424 respectively located on both sides of the fourth bevel gear 4222. Two second racks 200b can then be installed to mesh with the two second gears 424 respectively, thus enhancing the stability of driving the right earphone holder 200 to move. Optionally, the two second racks 200b are spaced apart on one side of the right earphone holder 200 to ensure the smooth movement of the right earphone holder 200 and prevent uneven force on the right earphone holder 200, which could cause it to tilt or even jam.

[0093] To ensure structural reliability, a first bracket 710 for mounting the first gear shaft 411 and a second bracket 720 for mounting the second gear shaft 421 can be provided inside the housing 100. The first gear shaft 411 can be rotatably connected to the first bracket 710, and the second gear shaft 421 can be rotatably connected to the second bracket 720. The first bevel gear 4121 and the first gear shaft 411 can be fixed together by a retaining circlip, and correspondingly, the third bevel gear 4221 and the second gear shaft 421 can be fixed together by a retaining circlip. Furthermore, the housing 100 also provides a third bracket 730 for mounting the first rotating shaft 413 and a fourth bracket 740 for mounting the second rotating shaft 423.

[0094] In one embodiment of this application, please refer to Figure 2The headphone holder 200 includes a support portion 210 and a cover plate 220. The support portion 210 is provided with a headphone slot for holding headphones and is connected to a transmission structure. The cover plate 220 is located on the outside of the support portion 210. The housing 100 is provided with an opening 103 for the headphone holder 200 to pass through. When the headphone holder 200 is stored in the housing 100, the cover plate 220 covers the opening 103, and the outer surface of the cover plate 220 is flush with the outer wall of the housing 100.

[0095] This embodiment illustrates the structure of the headphone holder 200. The support portion 210 is used to hold the headphones, and the cover plate 220 is located on the outside of the support portion 210. When the headphone holder 200 is housed inside the housing 100, the outer surface of the cover plate 220 is flush with the outer wall of the housing 100. This arrangement ensures the integrity of the headphone case's appearance, eliminating the need for an additional outer cover structure and simplifying the overall structure. A rack is located on the inside of the support portion 210, and its connection to the transmission structure is achieved through the rack.

[0096] Optionally, the headphone holder 200 is a one-piece structure, which can be formed by molding or 3D printing.

[0097] Further, please refer to Figure 4 , Figure 6 as well as Figure 8 The housing 100 is provided with a second limiting member 501, which abuts against the support portion 210 when the earphone holder 200 extends out of the housing 100. In this embodiment, the second limiting member 501 within the housing 100 limits the extension length of the earphone holder 200, preventing it from detaching from the housing 100. In practical applications, a protrusion 211 can be provided on the side of the support portion 210 opposite to the cover plate 220. The protrusion 211 abuts against the second limiting member 501, ensuring the limiting function of the earphone holder 200.

[0098] In one embodiment, please refer to Figure 3 The housing 100 is also provided with a limiting rib 502 to limit the earphone inside the support 210.

[0099] In this embodiment, by providing a limiting rib 502 inside the housing 100, the earphones inside the earphone holder 200 can be limited, preventing the earphones from falling off during shaking or flipping of the earphone case.

[0100] Optionally, the housing 100 is provided with two limiting ribs 502, each limiting rib 502 corresponding to limiting one earphone.
