Earphone Case

[0001] This application claims priority to Chinese Patent Application No. 202422482622.4, filed on October 14, 2024, entitled "Earphone Case", the entire contents of which are incorporated herein by reference.

[0002] [Technical Field]

[0003] This application relates to the field of headphone accessories technology, specifically a headphone case.

[0004] [Background Technology]

[0005] Headphones are a widely used electronic device in modern life. Headphone cases, as headphone accessories, primarily serve two functions: storing the headphones and charging them. Currently, most headphone cases have a flip-top or sliding design, allowing users to open and close them.

[0006] Among the sliding headphone cases on the market, the guide rail and slide groove type is generally used. A guide rail and a slide groove are designed on the upper shell and the lower shell respectively. The guide rail and the slide groove can slide against each other. However, the guide rail and slide groove type has the problem of obvious wobbling when sliding.

[0015] Furthermore, the clearance between the sliding member and the sliding channel is 0.03~0.05mm.

[0016] Furthermore, the first housing includes a bottom shell and a bottom liner, the bottom liner being fixedly connected to the bottom shell, the sliding bracket being fixedly mounted on the bottom liner, and the bottom liner having a storage cavity.

[0017] Furthermore, the first housing is fixedly provided with a first magnetic element, and the second housing is fixedly provided with a second magnetic element. The first magnetic element and the second magnetic element can attract each other, thereby making the second housing and the first housing have a relatively fixed positional state.

[0018] Further, the first magnetic component includes a first magnet, a second magnet, a third magnet, and a fourth magnet, and the second magnetic component includes a fifth magnet, a sixth magnet, a seventh magnet, and an eighth magnet; wherein, the fifth magnet and the sixth magnet are located on the same side of the sliding member's axial direction, and the seventh magnet and the eighth magnet are located on the other side of the sliding member's axial direction; the fifth magnet and the seventh magnet are symmetrically arranged about the sliding member, and the sixth magnet and the eighth magnet are symmetrically arranged about the sliding member; when the first housing and the second housing are closed, the first magnet and the fifth magnet are aligned and attracted, the second magnet and the sixth magnet are aligned and attracted, the third magnet and the seventh magnet are aligned and attracted, and the fourth magnet and the eighth magnet are aligned and attracted; when the first housing and the second housing are open, the second magnet and the fifth magnet are aligned and attracted, and the fourth magnet and the seventh magnet are aligned and attracted.

Detailed Implementation Methods

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] In the description of this application, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0046] In the description of this application, it should be understood that the terms "length," "width," "thickness," "one side," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," and "third" are only used to reflect the textual structure and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0048] As shown in Figures 1 and 2, the earphone case embodiment of this application includes a first housing 100 and a second housing 200, the first housing 100 and the second housing 200 are slidably connected, and the first housing 100 can slide relative to the second housing 200 to an open state and a closed state.

[0049] As shown in Figures 2 and 3, the sliding bracket 111 is fixed to the first housing 100. The sliding bracket 111 has a sliding channel 1113 extending through its opposite sides. The sliding member 211 is fixed to the second housing 200. The sliding member 211 is inserted into the sliding channel 1113 and can slide relative to the sliding channel 1113, allowing the second housing 200 to be slidably connected to the first housing 100, enabling the first housing 100 and the second housing 200 to switch between a closed state and an open state. The sliding member 211 slides through the sliding channel 1113, so that the sliding member 211 is surrounded by the sliding bracket 111, achieving a shaft-hole fit between the sliding member 211 and the sliding bracket 111. This provides excellent guidance during sliding, achieving a tight fit and effectively preventing wobbling under current technological levels, making the parts easy to process while ensuring dimensional accuracy.

[0050] As shown in Figure 3, exemplarily, the first housing 100 may have a recessed storage cavity 115 for accommodating the earphones. In some embodiments, the second housing 200 may also have a recessed storage cavity 115 for accommodating the earphones. Of course, in other embodiments, the first housing 100 and the second housing 200 may share the storage cavity 115. When the first housing 100 and the second housing 200 are slid into a closed state, they together form a hollow storage cavity 115, in which the earphones can be placed. When the first housing 100 and the second housing 200 are slid into an open state, the earphones can be removed from the storage cavity 115 for wearing. This not only protects the earphones but also ensures their relative position within the earphone case, guaranteeing stability during charging.

[0051] For example, the earphone case may have a charging function. In some embodiments, a battery and a control circuit board may be disposed within the first housing 100. When the earphones are not in use, they can be stored in the sliding charging case, and the battery in the earphone case can charge the earphones, ensuring continuous use. Of course, the above embodiments are merely illustrative of the earphone case's function; in some other embodiments, a battery and a control circuit board may be disposed within the second housing 200, enabling the earphone case to have a charging function.

[0052] After adopting the above technical solution, the fit clearance between the slider 211 and the sliding channel 1113 can be continuously adjusted according to the requirements of sliding stability. Under otherwise unchanged conditions, a smaller fit clearance between the slider 211 and the sliding channel 1113 increases the process requirements, reduces the wobbling during sliding, and improves sliding stability. Conversely, a larger fit clearance between the slider 211 and the sliding channel 1113 reduces the process requirements, increases the wobbling during sliding, and correspondingly reduces sliding stability.

[0053] Optionally, under current process conditions, the sliding member 211 is used in conjunction with the sliding channel 1113, and the single-sided fitting clearance can be 0.01mm~0.1mm. In an optional embodiment, the single-sided fitting clearance can reach 0.03~0.05mm, specifically 0.03mm, 0.032mm, 0.035mm, 0.04mm, 0.043mm, 0.048mm, 0.05mm, etc. At this time, the fitting clearance between the sliding member 211 and the sliding channel 1113 is small and the fit is tight. Moreover, the sliding member 211 and the sliding channel 1113 are easy to process, which can ensure the dimensional accuracy. The shaft-hole fitting method will not have jamming problems due to the small clearance, the shaking generated by sliding is small, and the sliding stability is high.

[0054] The engagement length between the aforementioned slider 211 and sliding channel 1113 can be continuously adjusted according to the requirements of sliding stability. The engagement length range can be from a length greater than 0 to the length of slider 211. Under the condition that other factors remain unchanged, the longer the engagement length between slider 211 and sliding channel 1113, the greater the amount of material used for slider 211 and sliding support 111, the greater the space required for slider 211 and sliding support 111, the larger the engagement area between slider 211 and sliding channel 1113, the smaller the wobbling generated during sliding, and the higher the sliding stability. Conversely, the shorter the engagement length between slider 211 and sliding channel 1113, the less material used for slider 211 and sliding support 111, the smaller the space required for slider 211 and sliding support 111, the smaller the engagement area between slider 211 and sliding channel 1113, the greater the wobbling generated during sliding, and the lower the sliding stability.

[0055] There can be various quantities and mating methods for the sliding bracket 111 and the sliding member 211, and these mating methods can be combined to form new mating methods. This embodiment provides the following exemplary scenario:

[0056] In the first scenario, as shown in Figures 4 and 13, the sliding bracket 111 may include a first sliding bracket 1111 and a second sliding bracket 1112. The first sliding bracket 1111 and the second sliding bracket 1112 are respectively fixed to the first housing 100. The first sliding bracket 1111 is provided with a first sliding channel 11111 passing through its opposite sides, and the second sliding bracket 1112 is provided with a second sliding channel 11121 passing through its opposite sides. The sliding member 211 includes a first sliding rod 2111 and a second sliding rod 2112. The first sliding rod 2111 and the second sliding rod 2112 are arranged in parallel and are respectively fixed to the second housing 200. The first sliding rod 2111 is inserted into the first sliding channel 11111 and can slide relative to the first sliding channel 11111, and the second sliding rod 2112 is inserted into the second sliding channel 11121 and can slide relative to the second sliding channel 11121.

[0057] In some embodiments, there can be multiple sliding brackets 111 and sliding elements 211. By having one or more sliding brackets 111 and sliding elements 211 arranged in parallel and spaced apart, multiple sliding elements 211 can provide better guidance during sliding, significantly improving the problem of wobbling during sliding. Furthermore, with one or more sliding brackets 111 and sliding elements 211 arranged in parallel, the mating surface area of ​​the sliding brackets 111 and sliding elements 211 increases with the number of brackets 111 and sliding elements 211, resulting in greater stability during sliding.

[0058] Optionally, when multiple sliders 211 are provided, the cross-sectional width of the sliders 211 can be reduced, and the width of the sliding channel 1113 can be reduced accordingly. On the one hand, the material usage of the sliders 211 can be reduced while ensuring sliding stability, thereby reducing manufacturing costs. On the other hand, the space occupied by the sliders 211 in the second housing 200 can be reduced, effectively reducing the impact of the sliders 211 and the sliding bracket 111 on the thickness of the second housing 200, which facilitates reducing the size of the sliding headphone case and improving the space utilization of the sliding headphone case.

[0059] As shown in Figure 7, in some embodiments, the spacing L between the plurality of parallel sliding members 211 is less than or equal to the width D of the second housing 200. When the spacing between the sliding members 211 increases, the resistance arm during swaying increases, and the power required for swaying increases. Therefore, under otherwise unchanged conditions, a larger spacing L between the plurality of sliding members 211 results in better sway control between the two housings and improved sliding stability.

[0060] Optionally, the distance L between the multiple sliders 211 can exceed 60% of the width D of the second housing 200, thereby further improving the guiding effect of the sliders 211, reducing the offset of the second housing 200 when the sliders 211 slide, and improving the stability of the connection between the second housing 200 and the first housing 100.

[0061] The second scenario: As shown in Figure 5, the sliding bracket 111 may include a first sliding bracket 1111 and a second sliding bracket 1112. The first sliding bracket 1111 is provided with a first sliding channel 11111 that extends through its opposite sides, and the second sliding bracket 1112 is provided with a second sliding channel 11121 that extends through its opposite sides. The sliding member 211 is inserted into the first sliding channel 11111 and can slide relative to the first sliding channel 11111, and at the same time, the sliding member 211 is inserted into the second sliding channel 11121 and can slide relative to the second sliding channel 11121, so that the sliding member 211 can slide in both the first sliding channel 11111 and the second sliding channel 11121 at the same time, thereby improving the axial stability of the sliding bracket 111 on the sliding member, and at the same time increasing the mating area between the sliding bracket 111 and the sliding channel 1113, thereby improving the stability of the sliding.

[0062] In some embodiments, the number of sliding brackets provided on the slider 211 can be multiple. By having one or more sliding brackets 111 arranged in parallel and spaced apart, multiple sliding brackets can better guide the sliding direction of the sliding brackets during sliding, which can significantly improve the problem of wobbling during sliding. In addition, under the condition that other conditions remain unchanged, when one or more sliding brackets 111 and slider 211 are arranged in parallel, the mating surface area of ​​sliding brackets 111 and slider 211 increases with the increase of the number, resulting in more stable sliding.

[0063] The third scenario: As shown in Figure 6, the sliding channel 1113 includes a first sliding channel 11111 and a second sliding channel 11121 with parallel axes; the sliding member 211 includes a first sliding rod 2111 and a second sliding rod 2112, which are arranged in parallel and fixed to the second housing 200 respectively; the first sliding rod 2111 is inserted into the first sliding channel 11111 and can slide relative to the first sliding channel 11111, and the second sliding rod 2112 is inserted into the second sliding channel 11121 and can slide relative to the second sliding channel 11121.

[0064] In some embodiments, the sliding bracket 111 can have multiple sliding channels 1113, and correspondingly, the sliding member 211 passing through the sliding bracket 111 can also have multiple sliding channels 1113. By providing more than one sliding channel 1113 on the sliding bracket 111, the number of sliding members 211 is greater than the number of sliding channels 1113. Multiple sliding members 211 can play a better guiding role during sliding, which can significantly improve the problem of wobbling during sliding. Under the condition that other factors remain unchanged, the arrangement of more than one sliding channel 1113 makes the sliding bracket 111 and the sliding member 211 and the mating surface area increase with the increase of the number of sliding channels 1113, resulting in greater stability during sliding.

[0065] As shown in Figures 8, 9, and 13, in some embodiments, the second housing 200 may include a top housing 215 and a top inner liner 212. The top inner liner 212 is fixedly connected to the top housing 215. The top inner liner 212 is provided with a mounting groove 213, and mounting holes 2121 are respectively provided on the opposite side walls of the mounting groove 213. The two ends of the sliding member 211 are inserted into the mounting holes 2121 to achieve a fixed connection with the top inner liner 212. In this embodiment, a stable and detachable structure is formed by the inner liner, which not only ensures the stability of the structure but also facilitates maintenance and replacement of internal components.

[0066] Optionally, the top shell 215 and the top liner 212 can be fixedly connected by snap-fit, adhesive, or magnetic attraction.

[0067] As shown in Figures 3 and 13, in some embodiments, the first housing 100 may include a bottom liner 113 and a bottom shell 114. The bottom liner 113 and the bottom shell 114 are fixedly connected to form a stable and detachable structure, which is convenient for manufacturing and for maintenance and replacement of internal components.

[0068] Optionally, the bottom liner 113 and the bottom shell 114 can be fixedly connected by snap-fit, adhesive, or magnetic attraction.

[0069] Optionally, the sliding bracket 111 can be fixed to the bottom liner 113 by means of screws, adhesive, or other methods.

[0070] Optionally, the bottom liner 113 may be recessed to provide a storage cavity 115, in which the earphones can be placed.

[0071] The description of the first housing 100 and the second housing 200 above is merely illustrative and does not limit the specific structure and construction of the first housing 100 and the second housing 200 of this application. The specific structure and construction of the first housing 100 and the second housing 200 may also be of other types.

[0072] As shown in Figures 9 and 10, in some embodiments, the mounting hole 2121 can be a through hole penetrating the top inner liner 212, and the slider 211 is inserted into the mounting hole 2121. Optionally, a baffle 2122 can be provided in the top inner liner 212, and the baffle 2122 is fixed to the outside of the sliding channel 1113 away from the mounting groove 213 to fix the slider 211. Exemplarily, the mounting hole 2121 can also be a limiting hole partially recessed in the top inner liner 212, and the slider 211 is inserted into the recessed part of the limiting hole. Optionally, the mounting hole 2121 can be a through hole with a variable diameter, thereby achieving a better fixing effect on the slider 211 while installing it.

[0073] Optionally, the slider 211 can be a sliding shaft or a sliding rod. For example, as shown in FIG9, the axial section of the slider 211 in this embodiment can be circular. Of course, in some other embodiments, the axial section of the slider 211 can also be elliptical, square, triangular, pentagonal, or other convex shapes, and can also be concave shapes such as a pentagonal star. The slider 211 can be designed as a solid, or as hollow or partially hollow to reduce the amount of material used in the slider 211, thereby reducing the weight of the headphone case and saving costs.

[0074] In an optional embodiment, to improve the service life of the slider 211, the material of the slider 211 can be a wear-resistant material. Optionally, the wear-resistant material can be high manganese steel.

[0075] As shown in Figure 11, in an optional embodiment, to improve the service life of the slider 211, the slider 211 may include a slider body 2113 and a slider coating 2114. The material of the slider body 2113 may be a wear-resistant material. Optionally, the wear-resistant material may be high manganese steel.

[0076] In an optional embodiment, to improve the service life of the slider 211, the material of the slider coating 2114 can be a wear-resistant material. Optionally, the wear-resistant material can be high manganese steel.

[0077] As shown in Figure 12, in an optional embodiment, to improve the service life of the sliding bracket 111, the sliding bracket 111 may include a sliding bracket body 1114 and a sliding channel coating layer 1115. The sliding bracket body 1114 may be made of a wear-resistant material. Optionally, the wear-resistant material may be high manganese steel.

[0078] In an optional embodiment, the sliding channel coating 1115 can be a wear-resistant material. Optionally, the wear-resistant material can be high-manganese steel.

[0079] In one alternative embodiment, the friction between the slider 211 and the sliding bracket 111 can be altered by providing a non-smooth surface, a magnetic component, or the like. In other embodiments, the friction between the slider 211 and the sliding bracket 111 can also be altered by providing a non-smooth surface, a magnetic component, or the like.

[0080] As shown in Figure 8, in an optional embodiment, the first housing 100 of the earphone case may be provided with a display screen 116. The display screen 116 may be disposed on the outer wall of the first housing 100, including on the back plate opposite to the second housing 200, or on the side plate connecting the first housing 100 and the second housing 200.

[0081] In some embodiments, the top shell 215 of the second housing 200 of the headphone case may be provided with a display screen 116. The display screen 116 may be disposed on the back panel of the top shell 215 opposite to the first housing 100.

[0082] As shown in Figures 7 and 8, in some embodiments, with the cooperation of the dual sliding members 211 and the sliding bracket 111, the first housing 100 of the headphone case can be equipped with a display screen 116. That is, the sliding bracket 111 includes a first sliding bracket 1111 and a second sliding bracket 1112, and the sliding member 211 includes a first sliding rod 2111 and a second sliding rod 2112. The first sliding rod 2111 and the second sliding rod 2112 are arranged in parallel and respectively inserted into the first sliding bracket 1111 and the second sliding bracket 1112. In this case, the distance L between the first sliding rod 2111 and the second sliding rod 2112 can be increased to between 70% and 100% of the width D of the second housing 200, so that the middle part of the first housing 100 does not need to be equipped with the sliding bracket 111, thereby leaving more space in the middle part of the first housing 100 to facilitate the installation of the display screen 116. This ensures the stability of the headphone case's sliding while giving the headphone case a more significant space advantage in terms of thickness.

[0083] Of course, the above embodiments are merely illustrative of the placement of the display screen 116 when the dual sliding members 211 and the sliding bracket 111 are in cooperation. In some embodiments, with various numbers and cooperation methods of the sliding brackets 111 and the sliding members 211, the middle portion of the first housing 100 may not have a sliding bracket 111, thereby leaving more space in the middle portion of the first housing 100 to facilitate the installation of the display screen 116 and ensure the sliding stability of the headphone case, giving the headphone case a more significant space advantage in terms of thickness. In some other embodiments, with various numbers and cooperation methods of the sliding brackets 111 and the sliding members 211, the display screen 116 may also be located in the second housing 200.

[0084] As shown in Figure 13, in some embodiments, the first housing 100 may be fixed with a first magnetic element 112, and the second housing 200 may be fixed with a second magnetic element 214. The first magnetic element 112 and the second magnetic element 214 can attract each other, thereby making the second housing 200 and the first housing 100 have a relatively fixed position.

[0085] It should be noted that both the first magnetic component 112 and the second magnetic component 214 can be constructed as magnets, and the cross-sectional shape of the magnets is not limited to circles or rectangles, but can be any suitable shape. An attractive force can be formed between the first magnetic component 112 and the second magnetic component 214, that is, the first magnetic component 112 and the second magnetic component 214 can be N pole to S pole, or S pole to N pole, to achieve the effect of alignment and attraction when the first housing 100 and the second housing 200 are opened and closed by magnets of different polarities.

[0086] As shown in Figures 14 and 15, by way of example, the first magnetic element 112 may include a first magnet 1121, a second magnet 1122, a third magnet 1123, and a fourth magnet 1124, and the second magnetic element 214 may include a fifth magnet 2141, a sixth magnet 2142, a seventh magnet 2143, and an eighth magnet 2144. The fifth magnet 2141 and the sixth magnet 2142 are located on the same side of the axis of the slider 211, and the seventh magnet 2143 and the eighth magnet 2144 are located on the other side of the axis of the slider 211. The fifth magnet 2141 and the seventh magnet 2143 are symmetrically arranged about the slider 211, and the sixth magnet 2142 and the eighth magnet 2144 are symmetrically arranged about the slider 211. When the first housing 100 and the second housing 200 are closed, the first magnet 1121 and the fifth magnet 2141 are aligned and attracted, the second magnet 1122 and the sixth magnet 2142 are aligned and attracted, the third magnet 1123 and the seventh magnet 2143 are aligned and attracted, and the fourth magnet 1124 and the eighth magnet 2144 are aligned and attracted. When the first housing 100 and the second housing 200 are open, the second magnet 1122 and the fifth magnet 2141 are aligned and attracted, and the fourth magnet 1124 and the seventh magnet 2143 are aligned and attracted.

[0087] As shown in Figures 16 and 17, exemplarily, the first magnetic element 112 includes a first magnet 1121, a second magnet 1122, a third magnet 1123, a fourth magnet 1124, a ninth magnet 1125, and a tenth magnet 1126, and the second magnetic element 214 includes a fifth magnet 2141, a sixth magnet 2142, a seventh magnet 2143, and an eighth magnet 2144. The fifth magnet 2141 and the sixth magnet 2142 are located on the same side of the axis of the slider 211, and the seventh magnet 2143 and the eighth magnet 2144 are located on the other side of the axis of the slider 211. The fifth magnet 2141 and the seventh magnet 2143 are symmetrically arranged about the slider 211, and the sixth magnet 2142 and the eighth magnet 2144 are symmetrically arranged about the slider 211. The first magnet 1121, the second magnet 1122, and the ninth magnet 1125 are located on the same side of the sliding direction, while the third magnet 1123, the fourth magnet 1124, and the tenth magnet 1126 are located on the other side of the sliding direction. The first magnet 1121 and the third magnet 1123 are symmetrically arranged about the sliding direction, as are the second magnet 1122 and the fourth magnet 1124, and the ninth magnet 1125 and the tenth magnet 1126. When the first housing 100 and the second housing 200 are closed, the first magnet 1121 and the fifth magnet 2141 are aligned and attracted, the second magnet 1122 and the sixth magnet 2142 are aligned and attracted, the third magnet 1123 and the seventh magnet 2143 are aligned and attracted, and the fourth magnet 1124 and the eighth magnet 2144 are aligned and attracted. The first housing 100 and the second housing 200 have two open positions. When the first housing 100 and the second housing 200 are in the first open position, the ninth magnet 1125 and the fifth magnet 2141 are aligned and attracted, and the tenth magnet 1126 and the seventh magnet 2143 are aligned and attracted. When the first housing 100 and the second housing 200 are in the second open position, the second magnet 1122 and the fifth magnet 2141 are aligned and attracted, and the fourth magnet 1124 and the seventh magnet 2143 are aligned and attracted.

[0088] Of course, the above embodiments are merely illustrative. The first magnetic component 112 and the second magnetic component 214 may include multiple sub-magnetic components to achieve multiple opening positions. There is no limitation on the position and number of sub-magnetic components. At the same time, the opening position may not be limited to one, but may include multiple opening positions to achieve multiple opening states when the headphone case slides.

[0089] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
