Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a headphone case and headphone kit. Background Technology

[0002] With the increasing popularity of wireless earbuds, the functionality, convenience, and user experience of the earbud charging case, as an important charging and storage accessory, are receiving more and more attention. Traditional earbud cases typically use mechanical clips or a single magnetic structure to secure the earbuds, which can lead to problems such as misplacement, poor charging contact, or inconvenience in retrieval. For example, if the left and right earbuds are similar in shape, users may mistakenly place them in the wrong slots, resulting in no charging or reduced charging efficiency. In addition, if the charging contacts of the earbuds are not stable in contact with the electrical contacts inside the case, it may affect the charging effect and even shorten the battery life.

[0003] In existing technologies, some earphone cases use magnetic-assisted positioning, but these typically rely on a single magnetic pole direction or a simple symmetrical layout, which cannot effectively distinguish between the left and right earphones. Furthermore, uneven distribution of magnetic force can cause the earphones to wobble inside the case, affecting charging stability. Additionally, some designs expose the magnetic components directly inside the earphone case, which, while enhancing the magnetic attraction, also requires considerable force to remove the earphones, impacting the user experience.

[0004] Therefore, there is an urgent need for an optimized earphone case design that can prevent misinstallation of the left and right earphones through differentiated magnetic pole orientation, improve charging stability through a reasonable magnetic attraction and electrical contact layout, and at the same time take into account both convenient access and structural reliability. Utility Model Content

[0005] Therefore, it is necessary to provide an earphone case and earphone kit that can prevent the left and right earphones from being misplaced by using differentiated magnetic pole directions, so that users can more quickly know whether the earphones are correctly placed in the corresponding earphone case.

[0006] An earphone case includes a case body, a cover, a magnetic component, and a charging component. The case body has two earphone compartments, and the interior of the case body forms an installation cavity. The cover is placed on the case body and detachably covers the earphone compartments, which are used to hold earphones. Both the charging component and the magnetic component are disposed in the mounting cavity. The charging component includes a battery and two sets of first electrical contacts. The two sets of first electrical contacts are electrically connected to the battery and are exposed in the two earphone compartments in a one-to-one correspondence to charge the earphones in the earphone compartments. The magnetic component includes two first magnetic elements, which are correspondingly arranged with the two earphone compartments, and the magnetic poles of the two first magnetic elements are opposite.

[0007] In one embodiment, the two magnetic poles of the first magnetic element are arranged along an axis, and the axis of the first magnetic element is oriented toward the corresponding earphone compartment.

[0008] In one embodiment, each group of the first electrical contacts includes two electrical contacts, and in the first electrical contacts and the first magnetic element corresponding to any of the said earphone compartments, the two electrical contacts in the first electrical contacts are symmetrically distributed about the axis of the first magnetic element.

[0009] In one embodiment, the perpendicular bisector between the two electrical contacts coincides with the axis of the first magnetic element.

[0010] In one embodiment, the first electrical contact is exposed at the bottom of the earphone compartment, and the first magnetic element is fixed to the mounting cavity in an area near the bottom of the earphone compartment.

[0011] In one embodiment, a bracket is provided in the mounting cavity, the bracket is located in the mounting cavity and on the bottom back side of the earphone compartment, the first magnetic element is installed in the bracket, and the first magnetic element is separated from the earphone compartment by the housing.

[0012] In one embodiment, the housing includes an upper shell and a lower shell, the upper shell and the lower shell being connected to form a closed mounting cavity, the cover being connected to the upper shell, the upper shell being recessed to form two earphone compartments, and the bracket being disposed on the side of the upper shell facing the lower shell.

[0013] In one embodiment, the two earphone compartments are identical in shape.

[0014] An earphone kit includes two earphones and the aforementioned earphone case. The two earphones are placed in the two earphone cases one-to-one. Each earphone is provided with a second magnetic element to attract a corresponding first magnetic element in the earphone case. The magnetic poles of the two second magnetic elements are opposite. Each earphone is provided with a second electrical contact to contact a corresponding first electrical contact in the earphone case.

[0015] In one embodiment, the second magnetic element in the earphone corresponding to each earphone compartment is parallel to the magnetic pole direction of the first magnetic element in the mounting cavity.

[0016] In the earphone case and earphone kit provided in this application, when the user places the earphones in the earphone case, the magnetic components inside the earphones and the corresponding magnetic components inside the earphone case generate a magnetic attraction effect, while the magnetic components inside the earphones and the non-corresponding magnetic components inside the earphone cases generate a repulsive effect. When incorrectly inserted (e.g., the left earphone is placed in the right earphone compartment), the magnetic pole repulsion will slightly push the earphones apart to prompt the user to adjust. The first electrical contact is electrically connected to the battery, enabling the earphones in the earphone case to be charged. The differentiated magnetic pole direction prevents the left and right earphones from being misplaced, allowing for faster detection of whether the earphones are in the correct earphone compartment.

[0023] With the increasing popularity of wireless earbuds, the functionality, convenience, and user experience of the earbud charging case, as an important charging and storage accessory, are receiving more and more attention. Traditional earbud cases typically use mechanical clips or a single magnetic structure to secure the earbuds, which can lead to problems such as misplacement, poor charging contact, or inconvenience in retrieval. For example, if the left and right earbuds are similar in shape, users may mistakenly place them in the wrong slots, resulting in no charging or reduced charging efficiency. In addition, if the charging contacts of the earbuds are not stable in contact with the electrical contacts inside the case, it may affect the charging effect and even shorten the battery life.

[0024] In existing technologies, some earphone cases use magnetic-assisted positioning, but these typically rely on a single magnetic pole direction or a simple symmetrical layout, failing to effectively distinguish between the left and right earphones. Furthermore, uneven magnetic force distribution can cause the earphones to wobble inside the case, affecting charging stability. Additionally, some designs expose the magnetic components directly inside the earphone compartment, which, while enhancing the attraction, requires significant force to remove the earphones, impacting the user experience. Therefore, there is an urgent need for an optimized earphone case design that can prevent misplacement of the left and right earphones through differentiated magnetic pole directions, improve charging stability through a reasonable magnetic and contact layout, and simultaneously ensure convenient placement and structural reliability.

[0025] refer to Figures 1-10 To address the aforementioned issues, this application provides an earphone case 30, comprising a case body 40, a cover, a magnetic component 60, and a charging component 70. The case body 40 has two earphone compartments 43, and an installation cavity 44 is formed inside the case body 40. The cover is disposed on the case body 40 and detachably covers the earphone compartments 43, which are used to hold earphones 20. The charging component 70 and the magnetic component 60 are both disposed in the installation cavity 44. The charging component 70 includes a battery 71 and two sets of first electrical contacts 72. The two sets of first electrical contacts 72 are electrically connected to the battery 71 and are exposed in the two earphone compartments 43 to charge the earphones 20 in the earphone compartments 43. The magnetic component 60 includes two first magnetic elements 61, which are correspondingly disposed with the two earphone compartments 43, and the magnetic poles of the two first magnetic elements 61 are opposite.

[0026] refer to Figures 1-5The earphone case 30 includes a case body 40, a lid, a magnetic component 60, and a charging component 70. The case body 40 and the lid form the overall outer casing of the earphone case 30. The magnetic component 60 and the charging component 70 are located inside the case body 40. The lid can be placed on the case body 40, and the lid and case body 40 can be connected by a hinge. Opening the lid allows the earphones 20 to be removed from the case body 40. In one embodiment, the case body 40 can be an ellipsoidal structure with a smooth outer surface, which improves the user's grip comfort. The case body 40 has two earphone compartments 43 for holding the earphones 20. Since the lid can be detachably placed on the earphone compartments 43, the user can easily open and close the lid with one hand. The shape of the earphone compartments 43 can be designed according to the shape of the earphones 20 to improve the compatibility between the earphones 20 and the case body 40, thereby improving the stability of the earphones 20 placed inside the case body 40.

[0027] Specifically, in this embodiment, the interior of the housing 40 forms a mounting cavity 44, and the charging component 70 is disposed in the mounting cavity 44. The charging component 70 is the core power supply system of the earphone case 30, used to provide stable and efficient charging for the earphones 20. Specifically, in some embodiments, the charging component 70 includes a battery 71 and two sets of first electrical contacts 72. The battery 71 can be a built-in rechargeable lithium battery 71 to provide power support for the earphone case 30 and the earphones 20. The battery 71 also has overcharge and over-discharge protection functions to ensure the normal use of the earphones 20. The two sets of first electrical contacts 72 are electrically connected to the battery 71 and are exposed one-to-one in the two earphone compartments 43 to charge the earphones 20 in the earphone compartments 43, ensuring stable contact when the earphones 20 are inserted and avoiding poor charging due to misalignment.

[0028] In some embodiments, the magnetic component 60 is disposed in the mounting cavity 44. The magnetic component 60 assists in the positioning and fixing of the earphone 20 with magnetic force, improving ease of use. Specifically, the magnetic component 60 includes two first magnetic elements 61, which are correspondingly disposed with two earphone compartments 43. The magnetic poles of the two first magnetic elements 61 are opposite. For example, each earphone compartment 43 has a built-in magnet at its bottom, with the left compartment magnet having its N pole facing upwards and the right compartment magnet having its S pole facing upwards. The side of the left earphone facing the earphone compartment 43 has the S pole, and the side of the left earphone facing the earphone compartment 43 has the N pole. The earphone 20 and the earphone compartment 43 magnets are polarity matched, achieving automatic adsorption and positioning. When incorrectly inserted (e.g., the left earphone is placed in the right earphone compartment), the magnetic pole repulsion will slightly push the earphone 20 away, prompting the user to adjust. The earphone case 30 provided in this application avoids misplacement of the left and right earphones through magnetic pole difference. When the user uses the earphones 20, they automatically attach and align when they are close to the earphone compartment 43, making the operation more convenient and allowing the user to quickly know whether the earphones 20 are correctly inserted into the corresponding earphone compartment 43. At the same time, the magnetic attraction can prevent the earphones 20 from shaking or falling out inside the case.

[0029] See Figures 1-10 The two magnetic poles of the first magnetic component 61 are arranged along an axis, with the axis of the first magnetic component 61 pointing towards the corresponding earphone compartment 43. Specifically, arranging the two magnetic poles of the first magnetic component 61 along an axis allows the two magnetic poles to be aligned along a defined axial direction, for example, this axis is directly opposite and points towards the center of its corresponding earphone compartment 43. The axial arrangement of magnetic poles allows the magnetic force of the first magnetic component 61 to be concentrated and released along the axial direction, forming a defined magnetic force guide line. When the earphone 20 approaches the corresponding earphone compartment 43, it will naturally slide into the correct position along this magnetic force line, achieving convenient and precise alignment. The axial arrangement ensures that the direction of the magnetic force is completely consistent with the insertion direction of the earphone 20, avoiding magnetic force dispersion. Compared with random magnetic pole arrangement, this design can improve the effective attraction force and ensure that the earphone 20 is firmly in place. At the same time, when the axis of the magnetic component points to the center of the earphone compartment 43, it can maximize the utilization of the internal space of the accommodating cavity, ensuring sufficient magnetic attraction strength while avoiding unnecessary space waste and maintaining the compact appearance of the earphone case 30. In addition, when the user places the earphone 20 into the cavity, they can clearly feel the guiding force from the axial magnetic field. The guiding force helps to align the position and greatly improves the convenience of blind operation.

[0030] See Figures 4-8 In this embodiment, each group of first electrical contacts 72 includes two electrical contacts 721, both of which are located in the charging contact area of ​​the earphone compartment 43. In the first electrical contact 72 and the first magnetic element 61 corresponding to any earphone compartment 43, the two electrical contacts 721 are symmetrically distributed around the axis of the first magnetic element 61. This ensures that when the earphone 20 is inserted, the contact points on both sides are subjected to uniform force. The symmetrical layout ensures that the contact pressure between the earphone 20 and the electrical contacts 721 is balanced, improving contact stability and preventing poor contact or charging interruption due to uneven force on one side. For example, the earphone 20 automatically aligns with the charging position under magnetic attraction, and the two electrical contacts 721 simultaneously and tightly fit with the charging contacts of the earphone 20, reducing charging instability caused by shaking or slight displacement. Due to the symmetrical arrangement of the electrical contacts 721, the earphone 20 maintains a stable electrical connection during charging, reducing contact resistance fluctuations and improving charging efficiency. Suitable for sports scenarios, the charging case can maintain a stable charging state even if it is subjected to slight vibration or tilt.

[0031] Furthermore, in some embodiments, the perpendicular bisector between the two electrical contacts 721 coincides with the axis of the first magnetic element 61, which can further enhance the contact strength between the earphone 20 and the two electrical contacts 721 and improve contact stability. For example, the two electrical contacts 721 of the charging system adopt a completely symmetrical layout, in which the perpendicular bisector (the perpendicular bisector of the line connecting the two contacts) coincides with the magnetic axis of the magnetic element. In this way, the magnetic axis, the perpendicular bisector of the electrical contacts 721, and the center line of the charging contact of the earphone 20 coincide, forming the most stable contact state. When the earphone 20 is attracted by the magnetic force, it will automatically adjust its position along the direction of the magnetic axis, so that the electrical contacts 721 on both sides obtain consistent contact strength, improve contact stability, and effectively improve the anti-displacement capability of the earphone case 30. Even if subjected to slight external force interference, the coaxial design can ensure that the earphone 20 quickly returns to the correct position and maintains a stable charging connection.

[0032] To fully secure the earphone 20 magnetically and improve its stability, the first electrical contact 72 is exposed at the bottom of the battery compartment 71, and the first magnetic component 61 is fixed in the area of ​​the mounting cavity 44 near the bottom of the battery compartment 71. Specifically, the first electrical contact 72 is located at the bottom of the earphone compartment 43 and is partially exposed so that it can directly contact the charging contacts of the earphone 20 placed in the earphone compartment 43, achieving a stable electrical connection. Simultaneously, the first magnetic component 61 is fixedly installed inside the mounting cavity 44 and located near the bottom of the earphone compartment 43, enabling it to generate sufficient magnetic force on the earphone 20, ensuring that the earphone 20 remains stable during storage. This layout design concentrates both the charging component 70 and the magnetic component 60 in the bottom area of ​​the earphone case 43. On the one hand, it makes the internal structure of the earphone case 30 more compact; on the other hand, since the electrical contacts and magnetic components are close to the bottom of the earphones 20, they can more effectively guide the earphones 20 to be correctly placed into the earphone case 43 and maintain stable contact during charging, avoiding charging interruption caused by external shaking.

[0033] Specifically, in this embodiment, a bracket 441 is provided in the mounting cavity 44. The bracket 441 is located on the bottom back side of the earphone compartment 43, that is, on the side close to the inner wall of the housing 40. The first magnetic component 61 is securely installed in the bracket 441 and separated from the earphone compartment 43 by the shell structure of the housing 40, so that the first magnetic component 61 is not directly exposed inside the earphone compartment 43. Since the first magnetic component 61 is separated from the earphone 20 by the bracket 441 structure, the first magnetic component 61 will not directly contact the earphone 20. The magnetic force is reasonably controlled, which can ensure that the earphone 20 is securely attracted, and avoid the user having to exert effort to take the earphone 20 out due to excessive magnetic force. The cooperation between the bracket 441 and the housing 40 enhances the sealing of the mounting cavity 44, prevents external dust or liquid from entering the internal electronic components, and improves the durability and reliability of the earphone 20. In some embodiments, the inner wall shape of the bracket 441 is adapted to the shape and structure of the first magnetic element 61. For example, the first magnetic element 61 is a rectangular block structure, and the bracket 441 is configured as a frame-type or tray-type structure that matches the mounting cavity 44. The bracket 441 has a positioning groove or snap-fit ​​structure inside that matches the shape of the first magnetic element 61, so that the first magnetic element 61 can be accurately fixed and avoid displacement when the headphone case 30 is opened, closed, or moved. During assembly, after the first magnetic element 61 is embedded in the positioning groove of the bracket 441, its magnetic end face maintains a certain distance from the inner wall of the case 40 to avoid direct contact with the headphones 20, thereby reasonably adjusting the magnetic attraction force. A magnetic conductive sheet or a magnetic shielding layer can be added to the bottom of the bracket 441 to further optimize the magnetic force distribution and ensure that the headphones 20 can be firmly attached when attracted, but will not be difficult to remove due to excessive magnetic force. In addition, reinforcing ribs or shock-absorbing buffer structures can be set on the edges of the bracket 441 to reduce the impact of external impacts on the internal first magnetic element 61.

[0034] In some embodiments, the headphone case 30 adopts a split shell design. Specifically, the case 40 includes an upper shell 41 and a lower shell 42, which are connected by a snap-fit ​​structure to form a sealed mounting cavity 44. The sealed mounting cavity 44 effectively prevents the intrusion of external dust and moisture. To facilitate the installation of the headphones 20, two headphone compartments 43 are recessed in the upper shell 41, each used to hold two headphones 20. The inner surface of the upper shell 41 can be precision machined, and two symmetrically distributed headphone compartments 43 are integrally formed by in-mold injection molding. Each headphone compartment 43 is adapted to the shape of the corresponding model of headphone 20 to ensure the stability and precise alignment of the headphone 20 when placed. The cover is connected to the upper shell 41. The connection between the cover and the upper shell 41 can be a snap-fit ​​connection. A torsion spring mechanism can be built into the pivot to enable the cover to achieve smooth opening and closing and to remain stably suspended at any angle. The bracket 441 is fixed on the side of the upper shell 41 facing the lower shell 42. Specifically, guide grooves and positioning posts can be provided around the bracket 441 to achieve quick and accurate alignment during the assembly of the lower shell 42.

[0035] Specifically, in some embodiments, the earphone case 30 contains two earphones 20. In some earphone devices, the left earphone and the right earphone are distinguished by their shapes and structures. However, for earphones 20 with identical left and right earphone shapes, the earphone compartments 43 in the earphone case 30 have identical shapes. In this case, when a user places the earphones 20 into the earphone compartments 43, it is easy to mistakenly place the left earphone into the right earphone compartment 43 and vice versa, resulting in the earphones 20 not being able to charge in time. The earphone case 30 provided in this application can effectively avoid the above situation. For example, when a user mistakenly places the left earphone into the right earphone compartment 43, the second magnetic element 21 inside the left earphone and the first magnetic element 61 on one side of the right earphone compartment 43 have the same magnetism, generating a repulsive force. This alerts the user that the earphone 20 is placed in the incorrect earphone compartment 43, thus preventing misplacement of the left and right earphones through differentiated magnetic pole directions. Users can more quickly determine whether the earphones 20 are correctly placed in the corresponding earphone compartments 43.

[0036] The headphone kit 10 of the second aspect of this utility model includes two headphones 20 and a headphone case 30 of the first aspect embodiment. The two headphones 20 are placed in two corresponding headphone compartments 43. Each headphone 20 is provided with a second magnetic element 21 to attract a corresponding first magnetic element 61 in the headphone case 30. The magnetic poles of the two second magnetic elements 21 are opposite. Specifically, for example, when the second magnetic element 21 in the left headphone compartment 43 is the negative pole, the first magnetic element 61 in the left headphone case 30 is the positive pole, and the positive and negative magnetic elements attract each other. At the same time, when the second magnetic element 21 in the right headphone compartment 43 is the positive pole, the first magnetic element 61 in the right headphone case 30 is the negative pole, and the positive and negative magnetic elements on the right side also attract each other. Meanwhile, each earphone 20 is provided with a second electrical contact 22 to contact the corresponding first electrical contact 72 in the earphone case 30. When the earphone 20 is magnetically guided to the correct position in the earphone case 43, the second electrical contact 22 will connect with the first electrical contact 72 in the earphone case 30 to achieve charging of the earphone 20. In some embodiments, the second magnetic element 21 in the earphone 20 corresponding to each earphone case 43 is parallel to the magnetic pole direction of the first magnetic element 61 in the mounting cavity 44. The parallel arrangement of the magnetic poles can improve the utilization efficiency of the magnetic force, and can achieve a strong adsorption effect with a smaller magnetic material. At the same time, it eliminates unnecessary magnetic interference and ensures that the left and right earphones will not affect each other when they are in adjacent positions. Since this embodiment adopts all the technical features of the earphone case 30 of the first aspect embodiment, this embodiment has all the beneficial effects brought by the first aspect embodiment, which will not be repeated here.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
