Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly. In one example, they can be a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection, an electrical connection, or a connection that allows communication between them; they can be a direct connection or an indirect connection through an intermediate medium; they can be the internal connection of two elements or the interaction between two elements.

[0037] Referring to Figure 1, the headphone system 300 provided in this embodiment includes headphones 200 and a charging case 100. The charging case 100 is used to charge the headphones 200. Since the headphone system 300 in this embodiment includes the charging case 100, it is understood that the headphone system 300 includes at least the same beneficial effects as the charging case 100. Therefore, the beneficial effects of the headphone system 300 are described below in relation to the beneficial effects of the charging case 100.

[0038] In some embodiments of this application, the earphone 200 can be worn on a user's ear and can be used in conjunction with devices such as mobile phones, computers, smart wearable devices (such as smartwatches, smart bracelets, smart glasses, smart helmets, etc.), head-mounted displays, and virtual reality devices. Specifically, in some embodiments, the earphone 200 includes air-conduction earphones and bone-conduction earphones. Air-conduction earphones, also known as air-conduction headphones, are earphones that transmit sound through air vibrations. Bone-conduction earphones, also known as bone-conduction headphones, are earphones that convert sound into different mechanical vibrations and transmit sound waves through the skull, bony labyrinth, inner ear synovial fluid, cochlea, and auditory center.

[0039] It should be noted that the user's ear includes the external auditory canal, concha, cymba conchae, triangular fossa, helix, and antitragus. Among these, the concha, cymba conchae, and triangular fossa have a certain depth and volume in three-dimensional space. The external auditory canal is a curved tube extending medially from the external auditory meatus deep within the concha to the tympanic membrane.

[0040] Furthermore, in some embodiments, the earphone 200 includes a transducer assembly 210 (including a first transducer assembly 2101 and a second transducer assembly 2103), which is a structure in the earphone 200 used to enable the user to hear sound. In one example, when the earphone 200 is a bone conduction earphone, the transducer assembly 210 is configured to be located on the front side of the ear when the earphone 200 is worn, in which case the transducer assembly 210 does not block the external auditory canal. In another example, when the earphone 200 is an air conduction earphone, the transducer assembly 210 is configured to at least partially extend into at least one part of the concha, cymba conchae, and triangular fossa when the earphone 200 is worn. It should be noted that the embodiments described below only use a bone conduction earphone 200 as an example.

[0041] Furthermore, in some embodiments, the earphone 200 includes a battery compartment 220, a control compartment 230, a first ear hook assembly 240, a second ear hook assembly 250, and a back hook assembly 260 disposed between the first ear hook assembly 240 and the second ear hook assembly 250. The first ear hook assembly 240 and the second ear hook assembly 250 are respectively attached to the left and right ears. The battery compartment 220 may be disposed between the first ear hook assembly 240 and the back hook assembly 260, and the control compartment 230 may be disposed between the second ear hook assembly 250 and the back hook assembly 260. Both the first transducer assembly 2101 and the second transducer assembly 2103 are used to convert electrical signals into mechanical vibrations so that the user can hear sound.

[0042] Please refer to Figures 1 and 4. In some embodiments, the charging case 100 includes a rechargeable battery 110 and a charging circuit. When the earphone 200 is placed in the charging case 100, the charging circuit can deliver electrical energy from the rechargeable battery 110 to the earphone 200 to charge the earphone 200.

[0043] Furthermore, referring to Figure 2, in some embodiments, the charging case 100 is provided with a first electrical connector 17, and the earphone 200 is provided with a second electrical connector 280. When the earphone 200 is placed in the charging case 100, the first electrical connector 17 and the second electrical connector 280 are electrically connected.

[0044] Specifically, in some embodiments, when the first electrical connector 17 and the second electrical connector 280 are electrically connected, the charging case 100 and the earphone 200 can perform functions such as power transmission and data transmission. For example, when the first electrical connector 17 and the second electrical connector 280 are electrically connected, the charging circuit can transmit the electrical energy of the rechargeable battery 110 to the battery compartment 220 of the earphone 200 through the first electrical connector 17 and the second electrical connector 280, thereby charging the earphone 200. It should be noted that in some embodiments, the first electrical connector 17 can be at least one of the devices that can achieve electrical connection, such as a spring pin and a spring sheet; the second electrical connector 280 can be a device that can be electrically connected to the first electrical connector 17.

[0045] Furthermore, in some embodiments, the first electrical connector 17 includes a plurality of components, and the second electrical connector 280 includes a plurality of components. When the earphone 200 is placed in the charging case 100, the plurality of first electrical connectors 17 and the plurality of second electrical connectors 280 are electrically connected in a one-to-one correspondence.

[0046] Specifically, in some embodiments, a portion of the plurality of first electrical connectors 17 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of second electrical connectors 280 is used for power transmission, and another portion is used for signal transmission. The plurality of first electrical connectors 17 are arranged side-by-side on the charging case 100. This arrangement, compared to a non-side-by-side arrangement, reduces the space occupied by the first electrical connectors 17, making the structure more compact and facilitating the miniaturization of the charging case 100. Furthermore, it facilitates the alignment of the first electrical connectors 17 and the second electrical connectors 280, improving the convenience of electrical connection.

[0047] Please refer to Figures 2 to 4. The charging case 100 provided in this embodiment includes a base 10, a cover 20, and a lifting assembly 30. The cover 20 is connected to the base 10. The cover 20 and / or the base 10 are provided with a contoured groove 1011, which is used to limit the earphone 200. The contoured groove 1011 matches the outer contour of the earphone 200. The lifting assembly 30 is disposed on the base 10 and / or the cover 20. The lifting assembly 30 is used to raise and lower the cover 20 relative to the base 10 to switch between a pressed position and a released position. When the cover 20 is in the pressed position, the cover 20 presses the earphone 200 into the contoured groove 1011; when the cover 20 is in the released position, the cover 20 releases the earphone 200.

[0048] The base 10 is a structure within the charging case 100 used to support the earphones 200. In some embodiments of this application, both the rechargeable battery 110 and the charging circuit are housed within the base 10. This allows the base 10 to be relatively lightweight, reducing the likelihood of the charging case 100 tipping over when the earphones 200 are stored inside. The base 10 can be made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the base 10 is made of plastic, which makes the charging case 100 lighter and easier for users to carry.

[0049] The cover 20 is a structure in the charging case 100 that can cooperate with the base 10 to confine the earphones 200. In some embodiments of this application, the projection of the cover 20 in the height direction Z perpendicular to the charging case 100 coincides with the projection of the base 10 in the height direction Z perpendicular to the charging case 100; or, the projection of the cover 20 in the height direction Z perpendicular to the charging case 100 is located within the projection of the base 10 in the height direction Z perpendicular to the charging case 100. The material of the cover 20 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the cover 20 is made of plastic, which makes the charging case 100 lighter and easier for users to carry. It is understood that the material of the cover 20 and the material of the base 10 may be the same or different.

[0050] In some embodiments, the cover 20 and / or the base 10 are provided with a power connection port 103. The power connection port 103 may include, but is not limited to, a USB Type-C interface, and can be electrically connected to the rechargeable battery 110. Thus, when the power connection port 103 is connected to an external power source, the external power source can charge the rechargeable battery 110.

[0051] The contoured groove 1011 is a recess or cavity manufactured according to a specific shape (such as the outer contour of the earphone 200). In some embodiments of this application, the contoured groove 1011 matches the outer contour of the earphone 200; that is, the shape, size, and contour of the contoured groove 1011 are exactly the same or almost exactly the same as the shape, size, and contour of the earphone 200. The contoured groove 1011 facilitates the installation and positioning of the earphone 200 on the charging case 100; on the other hand, it can limit the installation of the earphone 200 on the charging case 100, improving the stability of the earphone 200 placed in the charging case 100.

[0052] In some embodiments, when the earphone 200 includes a battery compartment 220, the contoured groove 1011 is used to limit the battery compartment 220 and matches the outer contour of the battery compartment 220. That is, the shape, size, and contour of the contoured groove 1011 are exactly the same or almost exactly the same as the shape, size, and contour of the battery compartment 220, which can improve the stability of the battery compartment 220 placed in the charging case 100. It is understood that the second electrical connector 280 is disposed in the battery compartment 220 and electrically connected to the battery in the battery compartment 220.

[0053] In some embodiments, the base 10 has a contoured groove 1011. In other embodiments, the cover 20 has a contoured groove 1011. In still other embodiments, both the base 10 and the cover 20 have contoured grooves 1011. The contoured grooves 1011 on both the base 10 and the cover 20 match the outer contour of the earphone 200. It is understood that the orthographic projection of the contoured groove 1011 on the cover 20 onto the base 10 at least partially overlaps with the contoured groove 1011 on the base 10. The shape, size, and contour of the contoured groove 1011 on the base 10 and the contoured groove 1011 on the cover 20 may be the same or different.

[0054] It should be noted that, in some embodiments, the first electrical connector 17 extends into the contoured groove 1011. When the earphone 200 is housed in the contoured groove 1011, the first electrical connector 17 is electrically connected to the second electrical connector 280. That is, when the earphone 200 is housed in the contoured groove 1011, the plurality of first electrical connectors 17 and the plurality of second electrical connectors 280 are electrically connected in a one-to-one correspondence.

[0055] The lifting assembly 30 is a structure in the charging case 100 used to raise and lower the cover 20 relative to the base 10. In some embodiments of this application, the lifting assembly 30 is disposed on the base 10 and / or the cover 20. The pressing position can be: along the lifting direction of the charging case 100 (same as the height direction Z of the charging case 100), the lifting assembly 30 allows the cover 20 to move downward relative to the base 10 (the cover 20 moves relative to the base 10 in the direction from the cover 20 to the base 10); the releasing position can be: along the lifting direction of the charging case 100, the lifting assembly 30 allows the cover 20 to move upward relative to the base 10 (the cover 20 moves relative to the base 10 in the direction from the base 10 to the cover 20). It is understood that in a normal state (e.g., when the charging case 100 does not contain the earphones 200), the cover 20 can be in a pressed state, thus reducing the space occupied by the charging case 100 and making it easier for the user to carry.

[0056] Specifically, in some embodiments, when the cover 20 is in the pressed position, the cover 20 can press the earphone 200 into the contoured groove 1011, thereby limiting the earphone 200 and preventing it from moving or shaking in the charging case 100, thus improving the stability of the earphone 200 stored in the charging case 100. Simultaneously, the pressed position of the cover 20 also prevents the earphone 200 from moving or shaking in the charging case 100, which could lead to poor contact between the charging terminal of the earphone 200 (i.e., the second electrical connector 280) and the charging terminal of the charging case 100 (i.e., the first electrical connector 17), thereby improving the stability of the charging of the earphone 200 by the charging case 100 and ensuring the normal operation of the charging function and / or signal transmission function. When the cover 20 is in the released position, the earphone 200 can be placed into the charging case 100; or, the earphone 200 can be removed from the charging case 100.

[0057] In the charging case 100 of this application embodiment, the contoured groove 1011 can limit the earphone 200. The contoured groove 1011 matches the outer contour of the earphone 200, and the lifting component 30 can switch between a pressing position and a releasing position to selectively press or release the earphone 200, thereby preventing the earphone 200 from moving or shaking in the charging case 100 and improving the stability of the earphone 200 stored in the charging case 100.

[0058] In addition, the cover 20 can be raised and lowered relative to the base 10, which improves the applicability of the charging case 100 and prevents the charging case 100 from being unable to charge the earphones 200 due to their large size.

[0059] The charging case 100 will be further explained below with reference to the accompanying drawings.

[0060] Referring to Figures 2 and 3, in some embodiments, the base 10 is provided with a fastener 40, and the earphone 200 is provided with a mating part 270. The fastener 40 and the mating part 270 cooperate to fix the earphone 200 in the contoured groove 1011. Specifically, when the earphone 200 is placed in the charging case 100, the fastener 40 can cooperate with the mating part 270 to fix the earphone 200, thereby improving the stability of the earphone 200 stored in the charging case 100.

[0061] It should be noted that, in some embodiments, the engagement method of the fastener 40 and the mating part 270 includes, but is not limited to, snap-fit ​​engagement and magnetic engagement. In one example, when the engagement method of the fastener 40 and the mating part 270 is magnetic engagement, one of the fastener 40 and the mating part 270 is a first magnetic material, and the other is a second magnetic material or ferrous component that can attract the first magnetic material.

[0062] Furthermore, in some embodiments, the fastener 40 is a magnetic component, and the mating component 270 is a magnetic attractant, with the magnetic poles of the magnetic component and the magnetic attractant being opposite. This ensures the stability of the mating of the magnetic component and the magnetic attractant, thereby preventing the earphone 200 from moving or shaking in the charging case 100, which could lead to poor contact between the second electrical connector 280 and the first electrical connector 17, thus improving the stability of the charging case 100 in charging the earphone 200; on the other hand, it also improves the stability of the earphone 200 when stored in the charging case 100. For example, both the magnetic component and the magnetic attractant can be magnets, and when the earphone 200 is disposed in the contoured groove 1011, the S pole of the magnetic component is opposite to the N pole of the magnetic attractant.

[0063] Please refer to Figures 2 to 4. In some embodiments, the cover 20 and the base 10 together form an earphone compartment 101 for accommodating earphones 200. The earphone compartment 101 includes a contoured groove 1011.

[0064] Specifically, in some embodiments, when the lifting assembly 30 raises the cover 20 relative to the base 10, the size of the earphone compartment 101 in the height direction Z of the charging case 100 increases, and the cover 20 switches from a pressed position to a released position. In this case, the earphone 200 can be placed into the earphone compartment 101 and located in the contoured groove 1011; or, the earphone 200 can be removed from the earphone compartment 101. When the lifting assembly 30 lowers the cover 20 relative to the base 10, the size of the earphone compartment 101 in the height direction Z of the charging case 100 decreases, and the cover 20 switches from a released position to a pressed position. In this case, the cover 20 can press the earphone 200 into the contoured groove 1011, and the charging case 100 can charge the earphone 200.

[0065] In some embodiments, the earphone case 101 includes a first side 1013, a second side 1015, a third side 1017, and a fourth side 1019 connected in sequence. At least one of the first side 1013, the second side 1015, the third side 1017, and the fourth side 1019 of the earphone case is open to allow the earphone 200 to be inserted into the earphone case 101.

[0066] Specifically, in some embodiments, in the direction perpendicular to the height direction Z of the charging case 100, the earphone compartment 101 includes a first side 1013, a second side 1015, a third side 1017, and a fourth side 1019 connected in sequence. At least one of the first side 1013, the second side 1015, the third side 1017, and the fourth side 1019 of the earphone compartment is open. Thus, when the cover 20 is raised relative to the base 10, the earphones 200 can be placed into the earphone compartment 101 through the open side (including at least one of the first side 1013, the second side 1015, the third side 1017, and the fourth side 1019), thereby enabling the charging case 100 to charge and store the earphones 200.

[0067] In some embodiments of this application, the first side 1013 of the earphone compartment is closed, while the second side 1015, the third side 1017, and the fourth side 1019 of the earphone compartment are open. In this case, when the cover 20 rises relative to the base 10, the earphone 200 can be inserted into the earphone compartment 101 through the second side 1015 along the direction from the second side 1015 to the fourth side 1019 of the earphone compartment; or, the earphone 200 can be inserted into the earphone compartment 101 through the third side 1017 along the direction from the third side 1017 to the first side 1013 of the earphone compartment.

[0068] Please refer to Figures 3 and 4. In some embodiments, the cover 20 includes a main body 21 and an extension 23. The extension 23 extends from the main body 21 toward the base 10. The base 10 includes a seat 11 and a connector 13. The connector 13 extends from the seat 11 toward the cover 20. The extension 23 partially extends into the connector 13 and is able to move up and down relative to the connector 13 to selectively release or press the earphone 200 (shown in Figure 2).

[0069] Specifically, in some embodiments, a portion of the extension 23 can extend into the connector 13 and can move up and down relative to the connector 13. In this way, the connector 13 can guide and limit the movement of the extension 23, preventing the extension 23 from getting stuck during the movement, thereby improving the stability of the cover 20 moving up and down relative to the base 10.

[0070] It is understood that the projection of the extension 23 on the base 11 is located inside the connector 13, thereby ensuring that part of the extension 23 can extend into the connector 13, and thus enabling the extension 23 to rise and fall relative to the connector 13.

[0071] In some embodiments, the main body 21 and the extension 23 are an integral structure, that is, the main body 21 and the extension 23 can be integrally molded to form a whole, which can improve the stability of the connection between the main body 21 and the extension 23. In other embodiments, the main body 21 and the extension 23 are separate structures, that is, the main body 21 and the extension 23 are two different structures. In one example, the main body 21 and the extension 23 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connections or bolt connections. In another example, the main body 21 and the extension 23 can be joined together by a non-detachable connection method, including but not limited to adhesive or welding. It is understood that the connection method between the base 11 and the connector 13 is basically the same as the connection method between the main body 21 and the extension 23, and will not be described in detail here.

[0072] Furthermore, in some embodiments, the rechargeable battery 110 and the charging circuit are both disposed within the base 11. The base 11 includes a base body 111 and a top cover 113, with a connector 13 extending from the top cover 113 toward the cover body 20.
