Description

Technical Field

[0001] This invention relates to the field of headphone technology, and particularly to a headphone case. This invention also relates to a headphone assembly. Background Technology

[0002] Currently, with the continued development of the TWS (True Wireless Stereo) earphone market, the earphone case used to store and charge the two earphones has become an essential component.

[0003] In existing technologies, to facilitate charging and retrieving the earphones, two earphones are typically mounted on a support frame, which is designed as a lifting structure. This allows the two earphones to be raised for easy access. However, existing charging cases cannot lift only one earphone; both earphones must be raised or lowered together, preventing users from retrieving a single earphone.

[0004] Therefore, how to achieve the individual removal of any one earphone body and avoid the mutual interference between the removal operations of two earphone bodies is a technical problem faced by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an earphone case that allows for the individual removal of any one earphone unit, avoiding interference between the removal of two earphone units. Another purpose of this invention is to provide an earphone assembly.

[0006] To solve the above-mentioned technical problems, the present invention provides an earphone case, including a case body, a left earphone compartment and a right earphone compartment movably disposed within the case body, a driving component movably disposed on the case body, a first transmission mechanism and a second transmission mechanism, wherein the output end of the first transmission mechanism is connected to the left earphone compartment, and the output end of the second transmission mechanism is connected to the right earphone compartment; when the driving component moves to a first preset position, it forms a power connection with the input end of the first transmission mechanism, and when the driving component moves to a second preset position, it forms a power connection with the input end of the second transmission mechanism.

[0007] Preferably, when the driving component moves to the third preset position, it simultaneously forms a power connection with the input end of the first transmission mechanism and the input end of the second transmission mechanism.

[0008] Preferably, the housing has a mounting groove, and the driving component is slidably disposed in the mounting groove; the input end of the first transmission mechanism and the input end of the second transmission mechanism both extend into the mounting groove.

[0009] Preferably, the first transmission mechanism is located on one side of the mounting groove, and the input end of the first transmission mechanism passes through the groove wall on one side of the mounting groove; the second transmission mechanism is located on the other side of the mounting groove, and the input end of the second transmission mechanism passes through the groove wall on the other side of the mounting groove.

[0010] Preferably, the driving component is a driving ring rotatably embedded in the mounting groove. When the driving ring moves to a first preset position, it transmits rotational motion to the first transmission mechanism. When the driving ring moves to a second preset position, it transmits rotational motion to the second transmission mechanism.

[0011] Preferably, a limiting rib is provided on the outer edge of the drive ring, the limiting rib protruding outside the groove of the mounting groove, for manual operation and for forming an abutment with the groove of the mounting groove during the rotation of the drive ring.

[0012] Preferably, the first transmission mechanism includes a first transmission shaft, a first input component disposed at one end of the first transmission shaft, and a first output component disposed at the other end of the first transmission shaft. The first transmission shaft is rotatably disposed in the housing. The first input component is used to form a power connection with the drive ring, and the first output component is connected to the left earphone compartment.

[0013] Preferably, the outer edge of the first input component is used to engage with the inner wall of the drive ring for transmission.

[0014] Preferably, the first output component includes a first gear disposed on the first drive shaft and a first rack connected to the left earphone compartment, wherein the first gear meshes with the first rack.

[0015] Preferably, the second transmission mechanism includes a second transmission shaft, a second input component disposed at one end of the second transmission shaft, and a second output component disposed at the other end of the second transmission shaft. The second transmission shaft is rotatably disposed within the housing. The second input component is used to form a power connection with the drive ring, and the second output component is connected to the right earphone compartment.

[0016] Preferably, the outer edge of the second input component is used to engage with the inner wall of the drive ring for transmission.

[0017] Preferably, the second output component includes a second gear disposed on the second drive shaft and a second rack connected to the right earphone compartment, wherein the second gear meshes with the second rack.

[0018] The present invention also provides an earphone assembly, including an earphone case and an earphone body, wherein the earphone case is specifically the earphone case described in any of the above claims.

[0019] The earphone case provided by this invention mainly includes a case body, a left earphone compartment, a right earphone compartment, a driving component, a first transmission mechanism, and a second transmission mechanism. The case body is the main structure of the earphone case, primarily used to install and accommodate the other components. Both the left and right earphone compartments are located within the case body and can move independently within the case body along a preset direction to move the two earphones installed within them. This allows the earphones to be stored inside the case body for charging, or moved to protrude outside the case body for easy user access. The driving component is located on the case body and can move along a preset direction to adjust its installation position on the case body. It is mainly used to generate power and output power to target components, such as the first or second transmission mechanism. The first transmission mechanism is housed within the housing, with its output connected to the left earphone compartment. Its input is selectively connected to a driving component, allowing power to be transmitted from the driving component to the input. After transmission and conversion by the first transmission mechanism, the power is output to the left earphone compartment, driving it to move in a preset direction to retract and reveal the left earphone. The second transmission mechanism is also housed within the housing, with its output connected to the right earphone compartment. Its input is selectively connected to a driving component, allowing power to be transmitted from the driving component to the input. After transmission and conversion by the second transmission mechanism, the power is output to the right earphone compartment, driving it to move in a preset direction to retract and reveal the right earphone. Importantly, during the process of the drive component moving in a preset direction within the housing, it will pass through at least two preset positions. When the drive component moves to the first preset position, it will form a power connection with the input end of the first transmission mechanism; and when the drive component moves to the second preset position, it will form a power connection with the input end of the second transmission mechanism.

[0020] Thus, the earphone case provided by this invention stores the left and right earphones respectively through left and right earphone compartments. The installation position is adjusted and selectively connected to the first or second transmission mechanism via the movement of a driving component. When the user only wants to retrieve one earphone, they simply move the driving component to the corresponding preset position, establishing a power connection between the driving component and the corresponding transmission mechanism, thereby driving the corresponding earphone compartment to move until the target earphone is exposed. The other earphone remains unaffected as it is not driven by the driving component. In summary, the earphone case provided by this invention allows for the individual retrieval of any one earphone, preventing the retrieval of two earphones from interfering with each other.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please refer to Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a specific embodiment of the present invention. Figure 2 for Figure 1 The longitudinal sectional view.

[0040] In one specific embodiment of the present invention, the earphone case mainly includes a case body 1, a left earphone compartment 2, a right earphone compartment 3, a driving component 4, a first transmission mechanism 5, and a second transmission mechanism 6.

[0041] Among them, box 1 is the main structure of the earphone box, which is mainly used to install and accommodate the other components.

[0042] Both the left earphone compartment 2 and the right earphone compartment 3 are located inside the housing 1, and both can move in a preset direction within the housing 1 to move the two earphones installed therein. This allows the two earphones to be stored inside the housing 1 for charging, or to be moved to protrude outside the housing 1 for easy access by the user.

[0043] The drive component 4 is mounted on the housing 1 and can move along a preset direction on the housing 1 to adjust the mounting position of the drive component 4 on the housing 1. It is mainly used to generate power and output the power to the target component, such as the first transmission mechanism 5 or the second transmission mechanism 6.

[0044] The first transmission mechanism 5 is installed inside the housing 1, and the output end of the first transmission mechanism 5 is connected to the left earphone compartment 2. As for the input end of the first transmission mechanism 5, it is selectively used to form a power connection with the driving component 4, so that the power of the driving component 4 can be transmitted to the input end of the first transmission mechanism 5. After transmission and conversion by the first transmission mechanism 5, the power is finally output to the left earphone compartment 2 through the output end of the first transmission mechanism 5, driving the left earphone compartment 2 to move in a preset direction, thereby realizing the storage and exposure of the left earphone body.

[0045] The second transmission mechanism 6 is also located inside the housing 1, and the output end of the second transmission mechanism 6 is connected to the right earphone compartment 3. As for the input end of the second transmission mechanism 6, it is selectively used to form a power connection with the driving component 4, so that the power of the driving component 4 can be transmitted to the input end of the second transmission mechanism 6. After transmission and conversion by the second transmission mechanism 6, the power is finally output to the right earphone compartment 3 through the output end of the second transmission mechanism 6, driving the right earphone compartment 3 to move in a preset direction, thereby realizing the storage and exposure of the right earphone body.

[0046] Importantly, during the process of the drive component 4 moving in the housing 1 along a preset direction, it will pass through at least two preset positions. When the drive component 4 moves to the first preset position, the drive component 4 will form a power connection with the input end of the first transmission mechanism 5. When the drive component 4 moves to the second preset position, the drive component 4 will form a power connection with the input end of the second transmission mechanism 6.

[0047] Thus, the earphone case provided in this embodiment stores the left and right earphones respectively through the left earphone compartment 2 and the right earphone compartment 3. The installation position is adjusted by the movement of the drive component 4, and a selective power connection is established with the first transmission mechanism 5 or the second transmission mechanism 6. When the user only wants to retrieve one earphone, they simply move the drive component 4 to the corresponding preset position, establishing a power connection between the drive component 4 and the corresponding transmission mechanism, thereby driving the corresponding earphone compartment to move until the target earphone is exposed. The other earphone, not being driven by the drive component 4, remains in its initial state and is unaffected.

[0048] In summary, the earphone case provided in this embodiment enables the individual removal of any one earphone, avoiding interference between the removal operations of two earphones.

[0049] In one optional embodiment regarding the left earphone compartment 2 and the right earphone compartment 3, both the left and right earphone compartments 2 and 3 can be located in the upper half of the housing 1, respectively on the left and right sides of the length direction of the housing 1. The left earphone compartment 2 contains the left earphone, and the right earphone compartment 3 contains the right earphone, making it easy for the user to identify. Simultaneously, for easy access, both the left and right earphone compartments 2 and 3 can move vertically within the housing 1, i.e., they can move vertically up and down within the housing 1. When both the left and right earphone compartments 2 and 3 rise vertically to a preset height, they protrude from the top surface of the housing 1, exposing the left and right earphones inside. Conversely, when both the left and right earphone compartments 2 and 3 descend vertically to a preset height, they are both embedded within the housing 1, effectively storing the left and right earphones inside.

[0050] For ease of description, the following description in this embodiment will use the vertical lifting and lowering movement of the left earphone compartment 2 and the right earphone compartment 3 within the housing 1 as an example. Obviously, those skilled in the art will know that the movement direction of the left earphone compartment 2 and the right earphone compartment 3 within the housing 1 is not limited to the vertical direction; other directions, such as the horizontal direction, can also be used.

[0051] To facilitate the installation and movement of the drive component 4 on the housing 1, this embodiment provides a mounting groove 11 on the housing 1. Generally, the mounting groove 11 is located on one side wall of the housing 1, such as in the middle area of ​​a side wall. The drive component 4 is specifically installed within the mounting groove 11 and forms a sliding connection with it, allowing it to move within the mounting groove 11 in a predetermined direction. For example, the drive component 4 can move linearly along the length or width of the mounting groove 11, with the linear movement extending until it abuts against the two side walls of the mounting groove 11. Correspondingly, to ensure that the drive component 4 can form a power connection with the first transmission mechanism 5 or the second transmission mechanism 6 during its movement within the mounting groove 11, in this embodiment, the input ends of both the first transmission mechanism 5 and the second transmission mechanism 6 extend into the mounting groove 11.

[0052] Of course, mounting slot 11 can also be replaced by mounting holes or other mounting structures, with the same effect.

[0053] Considering that the left earphone compartment 2 and the right earphone compartment 3 are usually located on opposite sides of the housing 1, to facilitate power transmission, shorten the power transmission path, and improve mechanical transmission efficiency, in this embodiment, the first transmission mechanism 5 and the second transmission mechanism 6 are also located on opposite sides of the housing 1, corresponding to the distribution of the left earphone compartment 2 and the right earphone compartment 3. Specifically, in this embodiment, the mounting slot 11 is located in the middle area of ​​the housing 1, while the first transmission mechanism 5 is located entirely on one side of the mounting slot 11, and the second transmission mechanism 6 is located entirely on the other side of the mounting slot 11. Simultaneously, the input end of the first transmission mechanism 5 directly penetrates into the mounting slot 11 from one side wall and extends to one side of the drive component 4; while the input end of the second transmission mechanism 6 directly penetrates into the mounting slot 11 from the other side wall and extends to the other side of the drive component 4. For example, as... Figure 2 As shown, the input end of the first transmission mechanism 5 directly enters the interior of the mounting groove 11 from the left side wall and extends to the left side of the drive component 4; while the input end of the second transmission mechanism 6 directly enters the interior of the mounting groove 11 from the right side wall and extends to the right side of the drive component 4. With this configuration, when the drive component 4 moves in the left-right direction within the mounting groove 11, it can easily form a power connection with either the input end of the first transmission mechanism 5 or the input end of the second transmission mechanism 6.

[0054] Of course, the input end of the first transmission mechanism 5 and the input end of the second transmission mechanism 6 can also extend into the interior of the mounting groove 11 without penetrating the groove wall of the mounting groove 11. For example, they can also extend into the interior of the mounting groove 11 by means of a crankshaft structure that bypasses the groove wall of the mounting groove 11.

[0055] like Figures 3-6 As shown, Figure 3 This is a schematic diagram showing the left earphone compartment 2 in a retracted state when the drive component 4 moves to the first preset position. Figure 4 This is a schematic diagram showing the left earphone compartment 2 in an exposed state when the driving component 4 moves to the first preset position. Figure 5 This is a schematic diagram showing the right earphone compartment 3 in a retracted state when the drive component 4 moves to the second preset position. Figure 6 This is a schematic diagram showing the right earphone compartment 3 in an exposed state when the drive component 4 moves to the second preset position.

[0056] Generally, the first preset position specifically refers to the position where the driving component 4 stops moving when it comes into contact with the side wall of the mounting groove 11 in the direction of the first transmission mechanism 5 within the mounting groove 11. This position is also the farthest position of the driving component 4 when it moves along that side within the mounting groove 11. Similarly, the second preset position specifically refers to the position where the driving component 4 stops moving when it comes into contact with the side wall of the mounting groove 11 in the direction of the second transmission mechanism 6 within the mounting groove 11. This position is also the farthest position of the driving component 4 when it moves along that side within the mounting groove 11.

[0057] Of course, the first and second preset positions are not fixed positions; in actual use, they can be a range and can be flexibly adjusted. For example, the first preset position can also be set at a position where the driving component 4 is a certain distance from one side wall of the mounting groove 11, as long as the driving component 4 is only connected to the input end of the first transmission mechanism 5 at the first preset position. Similarly, the second preset position can also be set at a position where the driving component 4 is a certain distance from the other side wall of the mounting groove 11, as long as the driving component 4 is only connected to the input end of the second transmission mechanism 6 at the second preset position.

[0058] like Figure 7 , Figure 8 As shown, Figure 7 This is a schematic diagram showing that when the drive component 4 moves to the third preset position, both the left earphone compartment 2 and the right earphone compartment 3 are in a retracted state. Figure 8 This is a schematic diagram showing the structure in which both the left earphone compartment 2 and the right earphone compartment 3 are exposed when the drive component 4 moves to the third preset position.

[0059] Furthermore, considering that users may need to take not only one earphone unit individually, but also two earphone units simultaneously, to expand the application scenarios of the earphone taking and placing device, in this embodiment, during the movement of the driving component 4 along a preset direction within the housing 1, in addition to the aforementioned first and second preset positions, it will also pass through a third preset position. Specifically, when the driving component 4 moves to the third preset position, it will simultaneously form a power connection with the input end of the first transmission mechanism 5 and the input end of the second transmission mechanism 6. Generally, the third preset position specifically refers to the position where the driving component 4 moves to the middle position along the preset direction within the mounting groove 11. For example, based on the first and second preset positions being the positions where the driving component 4 stops moving when it abuts against the two side walls of the mounting groove 11, the third preset position is specifically the middle position between the two side walls of the mounting groove 11.

[0060] Of course, this third preset position is not a fixed position. In actual use, it can be a range and can be flexibly adjusted. For example, the third preset position can also be appropriately offset to the left or right from the middle position of the two side walls of the mounting groove 11, as long as it is ensured that the drive component 4 can simultaneously form a power connection with the input end of the first transmission mechanism 5 and the input end of the second transmission mechanism 6 at the third preset position.

[0061] Furthermore, to facilitate the user's precise movement of the drive component 4 to the third preset position, this embodiment also adds a centering marker block 12 to the housing 1. Specifically, the centering marker block 12 is located at the edge of the groove of the mounting slot 11, and is mainly used to cooperate with the limiting rib 42 provided on the drive component 4. When the two are aligned with each other, it indicates that the drive component 4 has moved to the third preset position.

[0062] In one optional embodiment of the driving component 4, the driving component 4 is specifically a driving ring 41. Specifically, the driving ring 41 is annular and maintains rotational freedom within the mounting groove 11, enabling rotational movement (self-rotation). Of course, the linear movement and rotational movement of the driving ring 41 within the mounting groove 11 are independent of each other and do not affect each other. Correspondingly, in this embodiment, a ring groove (usually a non-complete ring) is formed on the groove wall of the mounting groove 11, and the driving ring 41 is specifically embedded in this ring groove, forming a sliding connection with the ring groove, enabling rotational movement along the ring groove. The ring groove acts as a guide for the rotational movement of the driving ring 41. With this configuration, when the drive ring 41 moves to the first preset position in the mounting slot 11, it will transmit the rotational motion to the first transmission mechanism 5. After being transmitted by the first transmission mechanism 5, the rotational motion is finally converted into linear motion and transmitted to the left earphone compartment 2, causing the left earphone compartment 2 to perform vertical lifting and lowering motion. When the drive ring 41 moves to the second preset position in the mounting slot 11, it will transmit the rotational motion to the second transmission mechanism 6. After being transmitted by the second transmission mechanism 6, the rotational motion is finally converted into linear motion and transmitted to the right earphone compartment 3, causing the right earphone compartment 3 to perform vertical lifting and lowering motion.

[0063] Furthermore, considering that the rotation of the drive ring 41 is usually manually operated by the user, a limiting rib 42 is added in this embodiment to facilitate the user's application of force to the drive ring 41. Specifically, the limiting rib 42 is located on the outer edge of the drive ring 41 and protrudes outside the groove of the mounting groove 11, allowing the user's fingers to easily grip and apply force. Simultaneously, during the rotation of the drive ring 41, the limiting rib 42 rotates synchronously with it. After the drive ring 41 rotates clockwise or counterclockwise by a certain angle, the limiting rib 42 will abut against the groove of the mounting groove 11, thereby limiting the clockwise or counterclockwise rotation of the drive ring 41. Generally, when the drive ring 41 rotates to its limit position, the left earphone compartment 2 and the right earphone compartment 3 simultaneously reach their lifting limit positions, such as rising to the top or descending to the bottom.

[0064] Similarly, not only can the limiting rib 42 protrude beyond the opening of the mounting groove 11, but the drive ring 41 itself can also partially protrude beyond the opening of the mounting groove 11. In this case, it is equivalent to the drive ring 41 being only partially embedded in the mounting groove 11, with a small portion exposed outside.

[0065] In one optional embodiment of the first transmission mechanism 5, the first transmission mechanism 5 mainly includes a first transmission shaft 51, a first input component 52, and a first output component 53. The first transmission shaft 51 is installed inside the housing 1, for example, inserted into the side wall of the housing 1, and maintains rotational freedom. The first input component 52 is located at one end of the first transmission shaft 51 and forms a power connection with the drive ring 41. The first output component 53 is located at the other end of the first transmission shaft 51 and is connected to the left earphone compartment 2. With this configuration, the rotational motion of the drive ring 41 can be transmitted to the first input component 52, thereby driving the first transmission shaft 51 to rotate, which in turn drives the first output component 53 to rotate, and finally the first output component 53 converts the rotational motion into linear motion and transmits it to the left earphone compartment 2.

[0066] In one alternative embodiment of the first input component 52, the outer edge of the first input component 52 engages with the inner wall of the drive ring 41 for transmission. Specifically, the first input component 52 can be a cylindrical part sleeved on the first drive shaft 51, and a first driven tooth 521, similar to a tooth structure, is provided on the outer edge of the first input component 52. Simultaneously, a drive tooth 43, also similar to a tooth structure, is provided on the inner wall of the drive ring 41. With this configuration, the outer edge of the first input component 52 can engage with the inner wall of the drive ring 41 for transmission, thereby smoothly transmitting the rotational motion of the drive ring 41 to the first input component 52 and the first drive shaft 51.

[0067] Of course, power can also be transmitted between the outer edge of the first input component 52 and the inner wall of the drive ring 41 through a structure such as a transmission key.

[0068] In one optional embodiment of the first output component 53, the first output component 53 mainly includes a first gear 531 and a first rack 532. The first gear 531 is fixed to the first drive shaft 51 and rotates synchronously with the first drive shaft 51. The first rack 532 is connected to the left earphone compartment 2, generally on the back side of the left earphone compartment 2, and meshes with the first gear 531. The arrangement direction of the first rack 532 on the left earphone compartment 2 depends on the direction of movement of the left earphone compartment 2, such as vertically. With this configuration, when the first drive shaft 51 rotates, it drives the first gear 531 to rotate synchronously. Through the meshing transmission between the first gear 531 and the first rack 532, the rotational motion of the first gear 531 is converted into the linear motion of the first rack 532, ultimately driving the left earphone compartment 2 to move in a preset direction, such as vertical lifting or lowering.

[0069] In one optional embodiment of the second transmission mechanism 6, the second transmission mechanism 6 mainly includes a second transmission shaft 61, a second input component 62, and a second output component 63. The second transmission shaft 61 is installed inside the housing 1, for example, inserted into the side wall of the housing 1, and maintains rotational freedom. The second input component 62 is located at one end of the second transmission shaft 61 and forms a power connection with the drive ring 41. The second output component 63 is located at the other end of the second transmission shaft 61 and is connected to the right earphone compartment 3. With this configuration, the rotational motion of the drive ring 41 can be transmitted to the second input component 62, thereby driving the second transmission shaft 61 to rotate, which in turn drives the second output component 63 to rotate, and finally the second output component 63 converts the rotational motion into linear motion and transmits it to the right earphone compartment 3.

[0070] In one alternative embodiment of the second input component 62, the outer edge of the second input component 62 engages with the inner wall of the drive ring 41 for transmission. Specifically, the second input component 62 can be a cylindrical component sleeved on the second transmission shaft 61, and a second driven tooth 621, similar to a tooth structure, is provided on the outer edge of the second input component 62. With this configuration, the outer edge of the second input component 62 can engage with the inner wall of the drive ring 41 for transmission, thereby smoothly transmitting the rotational motion of the drive ring 41 to the second input component 62 and the second transmission shaft 61.

[0071] Of course, power can also be transmitted between the outer edge of the second input component 62 and the inner wall of the drive ring 41 through a structure such as a transmission key.

[0072] In one optional embodiment of the second output component 63, the second output component 63 mainly includes a second gear 631 and a second rack 632. The second gear 631 is fixed to the second transmission shaft 61 and rotates synchronously with the second transmission shaft 61. The second rack 632 is connected to the right earphone compartment 3, generally to the rear area of ​​the right earphone compartment 3, and meshes with the second gear 631. The arrangement direction of the second rack 632 on the right earphone compartment 3 depends on the direction of movement of the right earphone compartment 3, such as vertical. With this configuration, when the second transmission shaft 61 rotates, it drives the second gear 631 to rotate synchronously. Through the meshing transmission between the second gear 631 and the second rack 632, the rotational motion of the second gear 631 is converted into the linear motion of the second rack 632, ultimately driving the right earphone compartment 3 to move in a preset direction, such as vertical lifting motion.

[0073] In addition, to improve the motion stability of the first drive shaft 51 and the second drive shaft 61, in this embodiment, the adjacent ends of the first drive shaft 51 and the second drive shaft 61 can be connected as a single unit to form a rotatable connection. For example, the end of the first drive shaft 51 is inserted into the countersunk hole at the end of the second drive shaft 61.

[0074] In another alternative embodiment of the drive component 4, the drive component 4 specifically adopts a drive gear. Similar to the drive ring 41 in the aforementioned embodiment, this drive gear can also form a meshing transmission with the first input component 52 and the second input component 62, the only difference being that the meshing changes from internal to external. The technical effect of the drive component 4 using a drive gear is the same as that of the drive ring 41 described above, and will not be repeated here.

[0075] This embodiment also provides an earphone assembly, which mainly includes an earphone case and an earphone body.
