[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] It should be understood that when used in the specification and the appended claims, the terms "comprise" and "include" indicate the presence of described features, whole, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, whole, steps, operations, elements, components and / or sets thereof.

[0030] ​It should also be understood that the terms used in the summary of the disclosure herein are merely used to describe particular embodiments and are not intended to limit the disclosure. As used in the summary of the disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0031] It should be further understood that the term "and / or" used in the summary of the disclosure and the appended claims means one or more of the associated listed items and all possible combinations thereof, and includes these combinations.

[0032] In conjunction Figure 1 As shown in the drawings, the earphone box protective sleeve provided by the embodiments of the disclosure includes a shell 10, a shell cover 20, and a connecting piece 30. The shell 10 is connected with the shell cover 20 through the connecting piece 30. The shell cover 20 and the shell 10 are respectively provided with an upper cavity 21 and a lower cavity 11. The shell cover 20 includes a lower edge 22, and the shell 10 includes an upper edge 12. When the shell cover 20 is closed on the shell 10, the lower edge 22 and the upper edge 12 are attached, and the upper cavity 21 and the lower cavity 11 together form a cavity for placing an earphone box. The earphone box protective sleeve further includes at least two magnetic groups 40. Each magnetic group 40 includes two magnetic pieces 41 respectively arranged on the lower edge 22 of the shell cover 20 and the upper edge 12 of the shell 10. When the shell cover 20 is closed on the shell 10, the two magnetic pieces 41 in each magnetic group 40 are magnetically connected.

[0033] In the embodiments, the shell 10 and the shell cover 20 are fixedly connected through the connecting piece 30. The connecting piece 30 enables the shell 10 and the shell cover 20 to be stably matched and ensures that the shell cover 20 can be effectively closed on the shell 10 to protect the earphone box in the cavity from external damage. To ensure the stable closure of the shell cover 20 and the shell 10, the earphone box protective sleeve of the disclosure is designed with at least two magnetic groups 40. Each magnetic group 40 includes two magnetic pieces 41, which are respectively arranged on the lower edge 22 of the shell cover 20 and the upper edge 12 of the shell 10. When the shell cover 20 is closed on the shell 10, the two magnetic pieces 41 in the magnetic group 40 are attracted by magnetic force to achieve stable connection. The design of magnetic connection enables the shell cover 20 and the shell 10 to be more tightly closed, reducing the situation that the protective sleeve cannot be normally closed. The two magnetic pieces 41 in each magnetic group 40 are respectively arranged on the lower edge 22 of the shell cover 20 and the upper edge 12 of the shell 10.

[0034] When the earphone box needs to be stored, the earphone box is placed in the lower cavity 11 of the shell 10, and then the shell cover 20 is aligned and covered on the shell 10. At this time, the lower edge 22 of the shell cover is attached to the upper edge 12 of the shell, and the magnetic members 41 in the magnetic group 40 are naturally attracted and connected. When the earphone box needs to be taken out, the shell cover 20 and the shell 10 can be separated, and the magnetic members 41 are separated from the magnetic attraction connection by slightly applying an external force, so as to open the earphone box protective sleeve and take out the earphone box.

[0035] Through the magnetic connection design, the earphone box protective sleeve can ensure stable magnetic connection between the shell cover 20 and the shell 10, reduce loosening or accidental opening of the shell cover 20 during use. At the same time, a plurality of magnetic members 41 are used to disperse the demagnetization risk, so as to ensure that a strong magnetic attraction force can be maintained after long-term use, and the durability of the earphone box protective sleeve is improved.

[0036] In an embodiment, the magnetic member 41 is radially symmetrical in shape.

[0037] In this embodiment, the shape of the magnetic member 41 is radially symmetrical, that is, the magnetic member 41 is symmetrically distributed around the center point or center axis. Specifically, each part of the magnetic member 41 is uniformly arranged along the direction radiating outward from the center point or center axis. Through this design, the use of the magnetic member 41 is more efficient and has better adaptability, especially in application scenarios that require uniform magnetic force distribution, which can ensure the stability of the magnetic member 41 and reduce problems that may be caused by uneven distribution. For example, the magnetic member 41 adopts a circular structure and is distributed on the lower edge 22 of the shell cover and the upper edge 12 of the shell. By reasonably arranging a plurality of magnetic members 41, the earphone box protective sleeve can provide stable magnetic attraction force when opening and closing, while reducing the risk of affecting the overall closing performance after demagnetization of a single magnetic member 41.

[0038] When the shell cover 20 is covered on the shell 10, the magnetic members 41 in each magnetic group 40 are attracted to each other by magnetic force to achieve closure. The magnetic member 41 can provide stable magnetic field distribution due to uniform shape, so that the adsorption effect is more reliable. At the same time, compared with the traditional strip-shaped magnetic member, the magnetic force of the magnetic member 41 of the present embodiment will be more concentrated in the same area, and the magnetic field will not decay unevenly after long-term use, thereby prolonging the service life of the earphone box protective sleeve.

[0039] In an embodiment, at least two magnetic groups 40 are symmetrically arranged along the center axis of the earphone box protective sleeve.

[0040] In this embodiment, to ensure stable adsorption connection between the shell cover 20 and the shell 10, at least two magnetic groups 40 are symmetrically arranged along the central axis of the earphone case protective sleeve. This arrangement ensures the balance of the magnetic connection and avoids the problem of insufficient unilateral adsorption force or uneven force when the shell cover 20 is closed. Each magnetic group 40 contains two magnetic pieces 41, which are arranged at the lower edge 22 of the shell cover (corresponding to the shell cover 20) and the upper edge 12 of the shell (corresponding to the shell 10), respectively. When the shell cover 20 is closed to the shell 10, the corresponding magnetic pieces 41 are adsorbed by magnetic force to form a stable magnetic connection. The magnetic groups 40 are symmetrically distributed along the central axis of the earphone case protective sleeve, that is, at least two magnetic groups 40 are arranged on the left and right sides of the lower edge 22 of the shell cover and the upper edge 12 of the shell.

[0041] In an embodiment, the magnetic group 40 is provided with at least 4 magnetic groups, of which at least 2 magnetic groups 40 are arranged close to each other, and at least another 2 magnetic groups 40 are arranged close to each other.

[0042] In this embodiment, at least 2 magnetic groups 40 are arranged close to each other on one side of the earphone case protective sleeve, and at least another 2 magnetic groups 40 are arranged close to each other on the other side, ensuring the symmetry of the overall structure and the balanced magnetic attraction effect. Through at least 4 magnetic groups 40, the shell cover 20 can be more firmly adsorbed to the shell 10 when closed. The multiple magnetic groups 40 work together, so that even if part of the magnetic pieces 41 have magnetic force decay due to long-term use, the overall closure stability can still be maintained.

[0043] In combination with Figure 2 and Figure 3 As shown in the figures, in an embodiment, the lower edge 22 of the shell cover and the upper edge 12 of the shell are provided with accommodating grooves 50 for accommodating the corresponding magnetic pieces 41.

[0044] In this embodiment, the lower edge 22 of the shell cover is provided with at least two accommodating grooves 50 for accommodating the magnetic pieces 41, so that they can be stably embedded in the shell cover 20. The upper edge 12 of the shell is provided with accommodating grooves 50 corresponding to the shell cover 20, which are also used to embed the magnetic pieces 41, so as to ensure that the magnetic pieces 41 can be accurately aligned when the shell cover 20 and the shell 10 are closed. The design of the accommodating grooves 50 can wrap the magnetic pieces 41, avoiding the loosening or falling off of the magnetic pieces 41 due to long-term use or external impact. The size of the accommodating grooves 50 matches the magnetic pieces 41, so that the magnetic pieces 41 can be flush with the surface of the shell cover 20 and the shell 10, ensuring uniform adsorption force when closed and improving closure stability.

[0045] In an embodiment, the bottom of the shell 10 is provided with a charging portion 13, which includes a charging avoiding hole 131, a dustproof piece 132 and a dustproof connecting rod 133 with elasticity. One end of the dustproof connecting rod 133 is connected with the shell 10, and the other end is connected with the dustproof piece 132, and the dustproof piece 132 is located on the charging avoiding hole 131.

[0046] In the embodiment, the charging avoiding hole 131 is located at the opening of the bottom of the shell 10, and the size thereof is matched with the charging port of the earphone box, so that the earphone box can be charged in the state of being placed inside the earphone box protective sleeve. The dustproof piece 132 is arranged above the charging avoiding hole 131, and can cover the charging avoiding hole 131 when not charging, so as to prevent dust and impurities from entering the charging port of the earphone box. The dustproof connecting rod 133 with elasticity is used to connect the dustproof piece 132 and the shell 10, so that the dustproof piece 132 remains connected with the shell 10 after being opened. One end of the dustproof connecting rod 133 is fixed to the shell 10, and the other end is connected with the dustproof piece 132, so that the dustproof piece 132 can be rotated or opened. The dustproof connecting rod 133 is made of elastic material, so as to have good resilience. After charging is completed, the dustproof piece 132 can be automatically reset to cover the charging avoiding hole 131 again, and the dustproof effect is improved.

[0047] When the user charges, the dustproof piece 132 is gently pried away from the charging avoiding hole 131. Due to the connection of the dustproof connecting rod 133, the dustproof piece 132 does not completely separate from the shell 10, but remains a certain range of movement, so as to be reset after charging is completed. After the charging avoiding hole 131 is exposed, the user can insert the charging wire into the charging port of the earphone box to complete the charging operation. After charging is completed, the user pulls out the charging wire, and the dustproof piece 132 is automatically reset under the elastic action of the dustproof connecting rod 133 to cover the charging avoiding hole 131 again, so as to prevent dust or foreign matters from entering the charging port area.

[0048] In an embodiment, one side of the dustproof piece 132 facing the lower cavity 11 is provided with a dustproof plug 1321 for plugging the charging port of the earphone box.

[0049] In the embodiment, the dustproof plug 1321 is made of flexible material (such as silica gel, rubber, etc.), and can adapt to the shape of the charging port of the earphone box to realize sealed covering and prevent dust or foreign matters from entering. The dustproof plug 1321 is integrally formed with the dustproof piece 132, so that when the dustproof piece 132 is opened, the dustproof plug 1321 can also be moved synchronously, and the charging operation is not affected.

[0050] In the uncharged state, the dustproof piece 132 is in the closed state, and the dustproof plug 1321 thereon plugs the charging port of the earphone box to form sealed protection and prevent dust from entering. When the user needs to charge the earphone box, the dustproof piece 132 is gently pried away, and the dustproof plug 1321 is separated from the charging port of the earphone box to expose the charging port. When the user pulls out the charging wire, the dustproof piece 132 is automatically reset under the elastic action of the dustproof connecting rod 133, and the dustproof plug 1321 is inserted into the charging port of the earphone box again to realize secondary sealed protection.

[0051] In an embodiment, the bottom of the shell 10 is further provided with a first sound transmission hole 14 and a second sound transmission hole 15, both of which are circular rectangular in shape.

[0052] In the present embodiment, the first sound transmission hole 14 and the second sound transmission hole 15 are both circular rectangular in structure, which can provide a larger sound transmission area and improve the sound propagation effect compared with the traditional single circular hole design. The circular rectangular design makes the edge of the sound transmission hole smooth without sharp corners, which can reduce the processing difficulty, improve the opening precision, and avoid affecting the sound quality propagation due to edge burrs. The first sound transmission hole 14 and the second sound transmission hole 15 are respectively arranged at the bottom of the shell 10, which ensures that the audio signal can still be smoothly transmitted after the earphone box is put into the protective sleeve and is not blocked by the structure. The arrangement of the sound transmission holes follows the symmetry principle, i.e., the first sound transmission hole 14 and the second sound transmission hole 15 are respectively located on both sides of the bottom of the shell 10, so that the sound can be uniformly distributed and the problem of uneven sound caused by single hole is avoided.

[0053] In combination with Figure 4 As shown in the figure, in an embodiment, the side edge of the shell 10 is provided with a light-transmissive charging display area 16 corresponding to the earphone box indicator light.

[0054] In the present embodiment, the charging display area 16 is made of a light-transmissive material (such as frosted PC, PMMA or TPU, etc.), which ensures that the indicator light can pass through the protective sleeve, so that the user can intuitively observe the charging status of the earphone box in different light environments. The thickness of the charging display area 16 is optimized to ensure that it can transmit light and has a certain wear resistance. The charging display area 16 is integrally formed with the shell 10 or independently embedded, which ensures that the appearance is flat and closely combined with the overall structure, thereby enhancing the durability of the protective sleeve.

[0055] In an embodiment, the shell 10 further comprises a hanging part 17 arranged near the upper edge 12 of the shell, which comprises a hanging through hole 171 for externally connecting a rope and / or a hanging auxiliary hole 172.

[0056] In the present embodiment, the hanging through hole 171 is used for threading a rope, a key ring or a metal hook, so that the user can easily fix the protective sleeve to an article of clothing, thereby increasing the convenience of carrying. The hanging auxiliary hole 172 (optional) is used to enhance the structural stability of the hanging part 17, or to connect additional accessories such as an anti-lost chain, a decorative part, etc. If the user needs additional mounting methods, the hanging auxiliary hole 172 can be used to install a double hanging rope or an additional safety buckle, thereby improving the flexibility of carrying.

[0057] The use mode of the hanging part 17 is as follows:

[0058] Single-point hanging mode (using the hanging through hole 171 or the hanging auxiliary hole 172 alone):

[0059] The user can pass a hanging rope, metal buckle or key ring through the hanging through hole 171, so that the earphone box protective sleeve can be hung on a bag, a belt, a key ring or other personal items, thereby facilitating carrying and taking.

[0060] Double-point hanging mode (simultaneously using the hanging through hole 171 and the hanging auxiliary hole 172):

[0061] If the user wants the earphone box protective sleeve to maintain a more stable hanging state, the hanging through hole 171 and the hanging auxiliary hole 172 can be simultaneously used, the shaking is reduced through a double-point fixing mode, and the durability and safety are improved.

[0062] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
