Description

[0001] This application is a divisional application. The parent application number is 202111057987.7, the application date is September 9, 2021, and the invention title of the parent application is: A headphone assembly. Technical Field

[0002] This application relates to the field of electronic product technology, specifically to an earphone case and earphone assembly. Background Technology

[0003] True wireless earbuds are becoming increasingly popular due to their convenience in carrying and using the lack of connecting wires. Typically, when not in use, users will place these earbuds in the charging case for charging and storage.

[0004] The earphones consist of a stem and a head. The stem is placed inside the earphone case, while the head extends out of the case for easy access by the user. Specifically, the user pinches the head of the earphone with two fingers and then pulls it out to detach it from the case. However, due to the smooth surface of the earphones and the curved structure of the head that fits into the ear canal, the operation of pinching the head of the earphone with two fingers and pulling it out is inconvenient and results in a poor user experience. Summary of the Invention

[0005] The purpose of this application is to provide an earphone case and earphone assembly that allow for easy removal of the earphones from the earphone case, thereby improving the user experience.

[0006] On one hand, embodiments of this application provide an earphone case for an earphone assembly, the earphone assembly including earphones and an earphone case; the earphones include a stem and a head; the earphone case includes a housing, the housing having a receiving portion for receiving the stem; the stem can slide relative to the receiving portion along an arc-shaped movement trajectory to the inside or outside of the receiving portion, and when the stem is located inside the receiving portion, at least part of the head extends out of the housing; the housing has a mounting groove, the internal space of the mounting groove forming the receiving portion, the mounting groove being an arc-shaped groove, the stem having an arc-shaped structure and adapting to the arc-shaped groove, the stem being able to slide along the mounting groove.

[0007] When you need to remove the earbuds from the charging case, there's no need to pinch the earbud head and pull it outwards. Simply push the earbud head with a single finger, and it will slide out of the case along an arc-shaped path. This is convenient and provides a good user experience. When you need to put the earbuds back into the case, simply place the bottom of the stem into the case and push the head to make the stem slide back into the case along an arc-shaped path. This is also very convenient.

[0008] The mounting slot is an arc-shaped slot, and the handle has an arc-shaped structure that fits into the arc-shaped slot. The handle can slide along the mounting slot. This design simplifies the overall structure of the headphone case, simplifies the manufacturing process, and effectively reduces costs.

[0009] Based on this aspect, the embodiments of this application also provide a first implementation method:

[0010] The mounting slot is equipped with a magnetic structure, which allows the earphones to be placed inside the earphone case.

[0011] Based on this aspect, the embodiments of this application also provide a second implementation method:

[0012] The case contains a rechargeable battery. When the earphones are placed inside the case, the battery inside the case can charge the earphones.

[0013] Based on one aspect and the first and second embodiments of one aspect, the present application also provides a third embodiment of one aspect:

[0014] The opening end of the mounting slot forms an abutment edge on one side facing the center of the arc-shaped movement trajectory. This abutment edge has a chamfered structure. The chamfered structure prevents damage to the headphones when they come into contact with this abutment edge, thus providing protection for the headphones.

[0015] Secondly, embodiments of this application provide an earphone assembly, including an earphone and an earphone case; the earphone includes a stem and a head; the earphone case includes a housing, the housing has a mounting groove, the interior space of the mounting groove forms a receiving portion, the receiving portion is used to receive the stem; the stem can slide relative to the receiving portion to the inside or outside of the receiving portion, and when the stem is located inside the receiving portion, at least part of the head extends out of the housing body.

[0016] When you need to remove the earbuds from the charging case, there's no need to pinch the earbud head and pull it outwards. Simply push the earbud head with a single finger to slide it out of the case. This is convenient and provides a good user experience. When you need to put the earbuds back into the case, simply place the bottom of the stem into the case and push the head to slide the stem back into the case. This is also very convenient.

[0017] Based on these two aspects, the embodiments of this application also provide a first implementation method for these two aspects:

[0018] The handle can slide relative to the receiving part along an arc-shaped movement trajectory to either inside or outside the receiving part. The mounting slot is an arc-shaped groove, and the handle has an arc-shaped structure that fits into the arc-shaped groove. By pushing the head of the earphone with a single finger, the earphone can slide relative to the case along an arc-shaped movement trajectory to the outside of the receiving part, making operation convenient and providing a good user experience. When it's time to put the earphone back into the earphone case, simply place the bottom end of the handle into the receiving part and push the head to make the handle slide back into the receiving part along the arc-shaped movement trajectory. The operation is also very convenient. The mounting slot is an arc-shaped groove, and the handle has an arc-shaped structure that fits into the arc-shaped groove. The handle can slide along the mounting slot. This design simplifies the overall structure of the earphone case, simplifies the manufacturing process, and effectively reduces costs.

[0019] Based on the first implementation of the two aspects, this application also provides a second implementation of the two aspects:

[0020] The single-sided gap between the inner wall of the mounting slot and the outer wall of the stem is 0-0.1mm. This ensures the stability of the earphone stem within the mounting slot while allowing for smooth sliding between them. This simplifies the earphone's structural design and effectively reduces costs. Furthermore, it ensures the stability of the earphone stem within the mounting slot, preventing wobbling, and allows for smooth sliding, facilitating the placement and removal of the earphones.

[0021] Based on the second implementation method of the two aspects, the embodiments of this application also provide a third implementation method of the two aspects:

[0022] The single-sided gap between the inner wall of the mounting slot and the outer wall of the stem is 0.025mm-0.05mm. This further ensures the smoothness of the earphone sliding in and out, thereby further improving the user experience.

[0023] Based on any of the first to third embodiments of the two aspects, this application also provides a fourth embodiment of the two aspects:

[0024] The opening end of the mounting slot forms an abutment edge on one side facing the center of the arc-shaped movement trajectory, and the abutment edge has a chamfered structure. The chamfered structure can prevent the headphones from being damaged when they come into contact with this abutment edge, thus providing protection for the headphones.

[0025] Based on the fourth implementation method of the two aspects, this application also provides a fifth implementation method of the two aspects:

[0026] The chamfer radius of the chamfer structure should not exceed 0.1mm. Setting the chamfer radius to no more than 0.1mm can prevent the headphones from rolling along the chamfer surface and getting stuck, ensuring that the headphones can slide smoothly out of the mounting slot and improving the user experience.

[0027] Based on any of the first to third embodiments of the two aspects, this application also provides a sixth embodiment of the two aspects:

[0028] When the handle is inside the receiving part, at least part of the head extends out of the upper end face of the box.

[0029] Based on the sixth implementation of the two aspects, this application also provides a seventh implementation of the two aspects:

[0030] The bottom of the mounting slot is higher than the center of the arc-shaped movement trajectory. This makes it easier for the stem to slide out of the mounting slot, making it easier to remove the earphones.

[0031] Based on any of the first to third embodiments of the two aspects, this application also provides an eighth embodiment of the two aspects:

[0032] The central angle of the arc-shaped motion trajectory is no less than 1.5°. This ensures smooth ejection of the earphones from the mounting slot, enhancing the user experience.

[0033] Based on any one of the first to third embodiments of the two aspects, this application also provides a ninth embodiment of the two aspects:

[0034] The case also features a mounting cavity that connects to the receiving section. Part of the earphone's head can be positioned inside the mounting cavity, while another part extends out. This increases the internal storage space of the case without changing its overall volume.

[0035] Based on any one of the first to third embodiments of the two aspects, this application also provides a tenth embodiment of the two aspects:

[0036] It also includes a lid that fits over the top of the case. The lid has a mounting space that accommodates any part of the head that protrudes from the case when it is closed. This allows the headphones to be stably positioned inside the case and is protected from damage.

[0037] Based on any one of the first to third embodiments of the two aspects, this application also provides an eleventh embodiment of the two aspects:

[0038] The earpiece is positioned to one side of the center of the arc-shaped movement trajectory. This ensures that when a finger interacts with the earpiece, the point of contact avoids the earpiece.

[0039] Based on any one of the first to third embodiments of the two aspects, this application also provides a twelfth embodiment of the two aspects:

[0040] The cross-sectional shape of the mounting groove and the cross-sectional shape of the handle are mutually compatible circular, elliptical, or triangular structures. This ensures the stability of the handle when it is located within the mounting groove.

[0041] Based on any one of the first to third embodiments of the two aspects, this application also provides a thirteenth embodiment of the two aspects:

[0042] The cross-sectional shape of the mounting groove is different from that of the handle. The mounting groove has two first mating surfaces. One first mating surface is on the side facing the center of the arc-shaped movement trajectory, and the other first mating surface is on the side away from the center. The handle has two second mating surfaces, which are respectively mated with the two first mating surfaces.

[0043] Based on the second aspect, and any of the first to third embodiments of the second aspect, this application also provides a fourteenth embodiment of the second aspect:

[0059] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] This application provides an earphone assembly, such as... Figure 1 As shown, the earphone assembly includes earphones 2 and an earphone case. Earphones 2 refer to true wireless earphones or other wire-free earphones that can be stored inside the earphone case. Figure 2 As shown, the earphone 2 includes a stem 21 and a head 22, the head 22 being provided with an earpiece, such as... Figure 3 As shown, the headphone case includes a case body 1, which has a receiving portion for receiving the stem 21 of the headphone 2.

[0061] A sliding pair can be formed between the receiving portion and the handle 21. This sliding pair has an arc-shaped movement trajectory, that is, the handle 21 can slide relative to the receiving portion along the arc-shaped movement trajectory to the inside or outside of the receiving portion, and, as Figure 1 As shown, when the handle 21 slides into the receiving part, the head 22 of the earphone 2 can at least partially protrude from the box 1. Specifically, it refers to the upper end face 14 of the box 1. When the user holds the earphone box in one hand, the part of the head 22 of the earphone 2 protruding is facing upward. Therefore, in this embodiment, the side of the head 22 protruding from the box 1 is called the upper end face 14.

[0062] Specifically, such as Figure 1 and Figure 3 As shown, in this embodiment, the housing 1 is provided with a mounting groove 11, and the inner cavity of the mounting groove 11 forms the aforementioned receiving portion. It is easy to understand that the earphones 2 are usually used in pairs. Therefore, the housing 1 is provided with two mounting grooves 11, each mounting groove 11 corresponding to one earphone 2.

[0063] When the earphone 2 stem 21 is located in the mounting slot 11 of the housing 1, if the user wants to remove the earphone 2 from the housing 1, they can directly apply a pushing force Fx to the part of the earphone 2 head 22 protruding from the upper end face 14 by applying a finger to the earphone 2. Figure 4 As shown, the component F1 of the thrust Fx along the tangential direction of the arc-shaped motion trajectory can act on the earphone 2, causing it to slide relative to the housing 1 along the arc-shaped motion trajectory, thereby realizing the operation of removing the earphone 2 from the housing 1. When it is necessary to place the earphone 2 into the housing 1, simply insert the earphone 2 stem 21 into the opening end of the mounting slot 11, and push the earphone 2 head 22 to slide the stem 21 along the mounting slot 11 until the stem 21 is located in the mounting slot 11.

[0064] In actual use, when a user's finger touches the head 22 of the earphone 2 and applies a pushing force Fx, the direction of this pushing force Fx can be parallel to the upper end face 14. The tangential component F1 causes the earphone 2 to slide out along the mounting groove 11. In practical application, due to friction between the finger and the head 22 of the earphone 2, the direction of the pushing force Fx during the pushing process can not only be from the outside to the inside along the upper end face 14 of the housing 1, but specifically from the outside to the inside, while simultaneously tilting upwards with a tendency to cause the earphone 2 to slide out of the mounting groove 11 along an arc-shaped trajectory (approximately along the tangential direction). Figure 4 As shown, if you place your finger on the head 22 of the earphone 2 and push the earphone 2 to the side outside the mounting slot 11, the earphone 2 can be smoothly slid out of the mounting slot 11 with a small amount of pushing force. The whole process can be operated with only one finger. There is no need to pinch the head 22 of the earphone 2 to ensure that the earphone 2 can be smoothly taken out of the box 1, thereby improving the user experience.

[0065] In other words, when it is necessary to remove the earphone 2 from the earphone case, there is no need to pinch the head 22 of the earphone 2 with your fingers and pull it outward. You only need to push the head 22 of the earphone 2 with a single finger. The operation is convenient and the user experience is good. When it is necessary to put the earphone 2 back into the earphone case, you only need to insert the bottom end of the stem 21 into the mounting slot 11 and push the head 22 so that the stem 21 slides in the opposite direction along the mounting slot 11 into the case body 1. The operation is also convenient.

[0066] Specifically, such as Figure 4As shown, the earpiece of the head 22 of the earphone 2 is positioned on the side facing the center O of the arc-shaped movement trajectory. When the earphone 2 is removed, it is done by pushing the head 22 of the earphone 2 with a finger. Specifically, the point of contact between the finger and the head 22 of the earphone 2 is located on the side of the head 22 away from the earpiece, so as to avoid direct contact between the finger and the earpiece of the earphone 2. Of course, in this embodiment, the finger can also be applied to other side positions of the head 22, as long as the earpiece is not positioned on the side away from the center O, so that the point of contact between the finger and the earpiece is avoided.

[0067] like Figure 5-7 As shown, the inner wall of the mounting groove 11 is smooth, and the axis of the mounting groove 11 is an arc-shaped structure. At the same time, the handle 21 is also set to an arc-shaped structure that is compatible with the mounting groove 11. The handle 21 can slide along the axial direction of the mounting groove 11 to achieve sliding relative to the box 1 along an arc-shaped motion trajectory.

[0068] Because the curvature of the arc-shaped structure is relatively small, visually, this earphone 2 is not much different from earphones 2 currently on the market. Furthermore, the stem 21 has an arc-shaped structure, while the head 22 structure remains unchanged, so it will not affect the user's wearing experience. In other words, the mounting groove 11 essentially forms an arc-shaped sliding groove for the stem 21. The mounting groove 11 and the stem 21 are mutually compatible, allowing the stem 21 to slide relative to each other within the mounting groove 11.

[0069] Of course, in this embodiment, a slide rail with an arc-shaped motion trajectory can also be provided in the receiving part. The stem 21 of the earphone 2 can slide along the slide rail by setting a slider, which can also achieve the purpose of sliding the stem 21 relative to the box body 1 along the arc-shaped motion trajectory. When the mounting groove 11 is set as a groove with a smooth inner wall arc-shaped structure, the overall structure of the earphone box can be simplified. At the same time, the earphone 2 does not need to be set with a corresponding slider, which simplifies the processing and manufacturing process and effectively reduces costs.

[0070] Both the axis of the mounting groove 11 and the axis of the handle 21 are mutually adaptable arc-shaped structures. There are no restrictions on the specific cross-sectional shape of the mounting groove 11 or the handle 21. For example, the cross-sectional shapes of the mounting groove 11 and the handle 21 can be set to mutually adaptable circular, elliptical, triangular, polygonal, or irregular shapes, which can further ensure the stability of the handle 21 when it is located within the mounting groove 11. Furthermore, in this embodiment, the single-sided gap between the inner wall of the mounting groove 11 and the outer wall of the handle 21 is set to 0-0.1mm. This ensures the stability of the handle 21 of the earphone 2 within the mounting groove 11, preventing wobbling, and also allows for smooth sliding between the two, facilitating the placement and removal of the earphone 2.

[0071] Alternatively, the cross-sectional shape of the mounting groove 11 and the cross-sectional shape of the handle 21 can be set to be different. The mounting groove 11 has two first mating surfaces, one of which faces the center O of the arc-shaped movement trajectory, and the other is away from the center O. Correspondingly, the handle 21 has two second mating surfaces, which respectively mate with the two first mating surfaces. That is, when the handle 21 is in the mounting groove 11, the two first mating surfaces and the two second mating surfaces correspond one-to-one, and the single-sided gap between the two first mating surfaces and the two second mating surfaces is 0-0.1mm, which ensures that the position of the handle 21 of the earphone 2 is stable in the mounting groove 11 and avoids shaking. At the same time, it can also ensure that the two can slide smoothly, thus facilitating the taking and putting away of the earphone 2.

[0072] Furthermore, in this embodiment, the single-sided gap is preferably set to 0.025mm-0.05mm to further ensure the smoothness of the earphone 2 when sliding in and out, thereby further improving the user experience.

[0073] like Figure 5-7 As shown, the side of the opening end of the mounting groove 11 facing the center O forms an abutment edge 12. This abutment edge 12 has a chamfered structure, which is a rounded corner. When the earphone 2 is taken out, it can abut against the abutment edge 12 under the action of pushing force. The chamfered structure can prevent the earphone 2 from being damaged when it abuts against the abutment edge 12, thereby providing protection for the stem 21 of the earphone 2. The abutment edge 12 refers to the side that the earphone 2 will bend when it is pushed. The edge of the opening end of the mounting groove 11 can be provided with a chamfered structure around the circumference to protect the earphone 2 and prevent the stem 21 of the earphone 2 from being scratched and damaged during the removal and insertion process.

[0074] In this embodiment, the chamfer radius R of the chamfered structure of the abutment edge 12 is no greater than 0.1mm. If the chamfer radius R is too large, when the earphone 2 is pushed against the abutment edge 12, it is easy for the earphone 2 to roll along the chamfered surface of the abutment edge 12, forming a rocker-like structure with the abutment edge 12 as the fulcrum. This could cause the bottom end of the handle 21 to abut against the inner wall of the mounting groove 11, potentially causing it to jam. Setting the chamfer radius R of the chamfered structure to no greater than 0.1mm can prevent the earphone 2 from rolling along the chamfered surface and getting jammed, ensuring that the earphone 2 can smoothly slide out of the housing 1 along the mounting groove 11, thus improving the user experience. There is no requirement for the minimum radius of the chamfered structure, as long as it can meet the requirement that it will not damage the earphone 2 when it abuts against it.

[0075] like Figure 7As shown, the upper end face 14 of the housing 1 also has a mounting cavity 13. This mounting cavity 13 is located at the opening end of the mounting groove 11 and communicates with it. When the earphone 2 is placed inside the housing 1, the stem 21 is located inside the mounting groove 11, and part of the earphone 2's head 22 is located inside the mounting cavity 13. Furthermore, part of the earphone 2's head 22 extends out of the mounting cavity 13, that is, part of the head 22 extends out of the upper end face 14 of the housing 1, so that the user can push the earphone 2's head 21 with their finger to remove the earphone 2 from the housing 1. Figure 7 As shown, when the box body 1 is provided with the mounting cavity 13, the abutting edge 12 is located at the corner between the end of the mounting groove 11 and the mounting cavity 13.

[0076] The headphone case also includes a lid (not shown in the figure), which can be closed on the top of the case body 1 (i.e., the lid is located on the side of the case body 1 facing the upper end face 14). The lid also has an installation space for accommodating the head 22 of the headphone 2. When the lid is closed on the top of the case body 1, the installation space can accommodate the part of the head 22 that extends out of the upper end face 14 of the case body 1. The mounting groove 11 can communicate with the installation space, or the mounting groove 11, the mounting cavity 13 and the installation space can be connected in sequence to completely enclose the headphone 2 in the headphone case, so that the headphone 2 can be stably located in the case body 1 and protected.

[0077] In this embodiment, the specific shape of the installation space is not limited. For example, the installation space can be set to fit the part of the head 22 that protrudes from the upper end face 14 of the box body 1. In this case, when the top cover is closed on the top of the box body 1, the shape of the installation space matches the partial shape of the head 22. The installation space and the installation groove 11 can restrict the movement of the earphone 2 from both ends, ensuring that the earphone 2 can be stably located in the earphone box. Alternatively, after the top cover is closed with the box body 1, the inner wall of the installation space can abut against the head 22 to ensure that the earphone 2 can be stably located in the earphone box. Or, a magnetic structure can be provided in the installation groove 11, so that the earphone 2 can be stably located in the earphone box.

[0078] Specifically, there are no restrictions on the way the lid is set. The lid can be connected to the body 1 by means of hinge, pivot connection, or chain connection. That is, the lid can be detached from the top of the body 1 and connected by a chain to prevent loss. When the lid and body 1 are pivotally connected, there are no restrictions on the opening direction of the lid. It is just necessary to ensure that after the lid is opened, the user can push the head 22 of the earphone 2 to slide it out along the mounting groove 11. The lid should not interfere with the sliding of the earphone 2, nor affect the user's pushing operation of the earphone 2.

[0079] When the box 1 is provided with a mounting cavity 13 (such as...) Figure 7When the case body 1 and the case cover are fitted together, the stem 21 of the earphone 2 is located in the mounting groove 11, and the head 22 is partially located in the mounting space and partially located in the mounting cavity 13. The head 22 of the earphone 2 protrudes slightly from the end face of the case body 1. At this time, the height of the mounting space provided in the case cover can be appropriately reduced, and the volume of the case cover can be reduced accordingly. When the case body 1 does not have a mounting cavity 13 (as shown), Figure 5 When the case 1 is provided with only the mounting groove 11 for accommodating the stem 21, after the case 1 and the cover are fitted together, the head 22 of the earphone 2 is completely located in the mounting space. Both of the above-mentioned configuration methods are acceptable.

[0080] When the housing 1 is provided with a mounting cavity 13, the space between the side wall of the mounting cavity 13 and the outer wall of the housing 1 can form a space for accommodating connecting wires, electrical components, etc. The earphone case can also charge the earphones 2. Usually, a rechargeable battery is placed inside the housing 1. When the earphones 2 are placed inside the housing 1, the rechargeable battery inside the housing 1 can charge the earphones 2. Therefore, when the housing 1 is provided with a mounting cavity 13, although the volume of the housing 1 can be increased, the volume of the lid can also be reduced accordingly, ensuring that the overall volume of the earphone case remains unchanged. At the same time, it can also increase the accommodating space inside the housing 1, providing more space for the rechargeable battery, which is more conducive to improving the battery capacity and thus ensuring the battery life of the earphones 2.

[0081] When the housing 1 can charge the earphone 2 placed inside it, the inner wall of the mounting slot 11 can be provided with a first contact, and the outer wall of the stem 21 of the earphone 2 can be provided with a second contact. When the stem 21 of the earphone 2 is placed in the mounting slot 11, the first contact can contact the second contact, and the earphone 2 is charged through the built-in battery of the housing 1. Specifically, there are no restrictions on the first and second contacts; for example, one can be a contact head, and the other can be a ring-shaped contact surface arranged circumferentially.

[0082] The height of the bottom of the mounting slot 11 is not lower than the height of the center O. Specifically, for example... Figure 8As shown, the mounting groove 11 and the center O are both located on the same side of the upper end face 14 of the housing 1. The distance between the bottom end of the mounting groove 11 and the upper end face 14 of the housing 1 is the first distance L1, and the distance between the center O and the upper end face 14 of the housing 1 is the second distance L2. The first distance L1 is not greater than the second distance L2, that is, L1≤L2. In other words, the mounting groove 11 is located entirely above the center O, that is, the mounting groove 11 is located entirely on the side of the center O closer to the upper end face 14. The angle between the tangent direction of the arc-shaped motion trajectory at the opening end of the mounting groove 11 and the upper end face 14 is smaller. At this time, under the same thrust Fx, the tangential component F1 of Fx will be larger, which is more conducive to driving the stem 22 of the earphone 2 to slide out along the mounting groove 11. Similarly, when it is necessary to put the earphone 2 back into the housing 1, it is also convenient for the stem 21 to slide smoothly into the mounting groove 11.

[0083] The central angle α of the circular arc trajectory (e.g.) Figure 8 As shown, the arc-shaped motion trajectory satisfies α≥1.5°. Specifically, the length of the arc-shaped motion trajectory can be set according to the length of the stem 21 of the earphone 2 (the length of the mounting slot 11), and the radius of the arc-shaped motion trajectory can also be set according to the central angle α and the length of the mounting slot 11. The central angle α is set to α≥1.5°, preferably not less than 3° (i.e. α≥3°), to ensure that when the earphone 2 is taken out of the box 1, the tangential component of the pushing force is greater, which facilitates the smoothness of pushing the earphone 2 out of the mounting slot 11 and improves the user experience.

[0084] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
