[0049] Please see Figures 1 to 3 The headphone system 3000 provided in this embodiment includes headphones 2000 and a charging case 1000. The charging case 1000 is used to charge the headphones 2000. Since the headphone system 3000 in this embodiment includes the charging case 1000, it is understood that the headphone system 3000 includes at least the same beneficial effects as the charging case 1000. Therefore, for the beneficial effects of the headphone system 3000, please refer to the beneficial effects of the charging case 1000 described below.

[0050] In some embodiments of this application, the earphone 2000 can be worn on the 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 and smart helmets), head-mounted displays and virtual reality devices.

[0051] Specifically, in some embodiments, the headphone 2000 includes air-conduction headphones and bone-conduction headphones. Air-conduction headphones, also known as air-conduction headphones, are headphones that transmit sound through air vibrations. Bone-conduction headphones, also known as bone-conduction headphones, are headphones that convert sound into different mechanical vibrations and transmit sound waves through the skull, bony labyrinth, inner ear fluid, cochlea, auditory center, etc.

[0052] 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.

[0053] Furthermore, in some embodiments, the earphone 2000 includes a transducer assembly 2100 (including a first transducer assembly 2101 and a second transducer assembly 2103), which is a structure in the earphone 2000 used to enable the user to hear sound. In one example, when the earphone 2000 is a bone conduction earphone 2000, the transducer assembly 2100 is configured to be located on the front side of the ear when the earphone 2000 is worn, in which case the transducer assembly 2100 does not block the external auditory canal. In another example, when the earphone 2000 is an air conduction earphone 2000, the transducer assembly 2100 is configured to at least partially extend into at least one part of the concha, cymba conchae, and triangular fossa when the earphone 2000 is worn. It should be noted that the embodiments described below only use a bone conduction earphone 2000 as an example.

[0054] Furthermore, in some embodiments, the earphone 2000 includes a battery compartment 2200, a control compartment 2300, a first ear hook assembly 2400, a second ear hook assembly 2500, and a back hook assembly 2600 disposed between the first ear hook assembly 2400 and the second ear hook assembly 2500. The first ear hook assembly 2400 and the second ear hook assembly 2500 are respectively hooked onto the left and right ears. The battery compartment 2200 may be disposed between the first ear hook assembly 2400 and the back hook assembly 2600, and the control compartment 2300 may be disposed between the second ear hook assembly 2500 and the back hook assembly 2600. The first transducer assembly 2101 and the second transducer assembly 2103 are both used to convert electrical signals into mechanical vibrations so that the user can hear sound. When the earphone 2000 is in the wearing state, both the first transducer assembly 2101 and the second transducer assembly 2103 are located on the front side of the ear.

[0055] Please see Figure 1 and Figure 4 In some embodiments, the charging case 1000 includes a rechargeable battery 400 and a circuit board 500. When the earphone 2000 is placed in the charging case 1000, the circuit board 500 can transfer electrical energy from the rechargeable battery 400 to the earphone 2000 to charge the earphone 2000.

[0056] Furthermore, please combine Figure 2 and Figure 3 In some embodiments, the charging case 1000 is provided with a first electrical connector 250, and the earphone 2000 is provided with a power terminal 2700. When the earphone 2000 is placed in the charging case 1000, the charging terminal 250 and the power terminal 2700 are electrically connected.

[0057] Specifically, in some embodiments, when the charging terminal 250 and the power receiving terminal 2700 are electrically connected, functions such as power transfer and / or data transfer can be realized between the charging case 1000 and the earphone 2000. For example, when the charging terminal 250 and the power receiving terminal 2700 are electrically connected, the circuit board 500 can transfer the electrical energy of the rechargeable battery 400 to the battery compartment 2200 of the earphone 2000 through the charging terminal 250 and the power receiving terminal 2700, thereby charging the earphone 2000. It should be noted that in some embodiments, the charging terminal 250 can be at least one of the devices that can realize electrical connection, such as a spring pin and a spring contact; the power receiving terminal 2700 can be a device that can be electrically connected to the charging terminal 250.

[0058] Furthermore, in some embodiments, the charging terminal 250 may include multiple terminals, and the power connection terminal 2700 may also include multiple terminals. When the earphone 2000 is placed in the charging case 1000, the multiple charging terminals 250 and the multiple power connection terminals 2700 are electrically connected one-to-one.

[0059] Specifically, in some embodiments, a portion of the plurality of charging terminals 250 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of power receiving terminals 2700 is used for power transmission, and another portion is used for signal transmission. The plurality of charging terminals 250 are arranged side-by-side on the charging box 1000. This arrangement, compared to a non-side-by-side arrangement, reduces the space occupied by the charging terminals 250, making the structure more compact and facilitating the miniaturization of the charging box 1000. Furthermore, it facilitates the alignment of the charging terminals 250 and the power receiving terminals 2700, improving the convenience of electrical connection.

[0060] Please see Figure 3 and Figure 4This application provides a charging case 1000. The charging case 1000 includes a sealing assembly 100 and a base 200. The base 200 has at least one through hole 600. The sealing assembly 100 is disposed in the base 200 and is used to at least prevent external fluid from entering the interior of the base 200 through the through hole 600.

[0061] Specifically, the charging case 1000 includes a base 200 and a cover 300. The base 200 includes a seat 210 and a connector 230, and is the structure in the charging case 1000 used to support the earphones 2000. In some embodiments of this application, the rechargeable battery 400 and the circuit board 500 are both disposed in the base 200, which makes the base 200 relatively heavy and reduces the possibility of the charging case 1000 tipping over when the earphones 2000 are stored in it. The base 200 is made of materials including but not limited to plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the base 200 is made of plastic, which makes the charging case 1000 lighter and easier for users to carry.

[0062] The cover 300 is a structure in the charging case 1000 that can cooperate with the base 200 to confine the earphones 2000. In some embodiments of this application, the projection of the cover 300 in the direction perpendicular to the height of the charging case 1000 coincides with the projection of the base 200 in the same direction; or, the projection of the cover 300 in the direction perpendicular to the height of the charging case 1000 is located within the projection of the base 200 in the same direction. The material of the cover 300 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the cover 300 is made of plastic, which makes the charging case 1000 lighter and easier for users to carry. It is understood that the material of the cover 300 and the material of the base 200 may be the same or different.

[0063] The cover 300 includes a main body 310 and an extension 330. The extension 330 extends from the main body 310 toward a base 200. The base 200 includes a seat 210 and a connector 230. The connector 230 extends from the seat 210 toward the cover 300. The extension 330 partially extends into the connector 230 and is movable relative to the connector 230. Specifically, in some examples, the extension 330 can move up and down relative to the connector 230 along a first direction (Z1 / Z2) to switch the cover 300 between a pressed position and a released position. In other examples, the extension 330 can also move relative to the connector 230 along a second direction (X1 / X2). In still other examples, the extension 330 can also move relative to the connector 230 along a third direction (Y1 / Y2).

[0064] Specifically, in the embodiment where the extension 330 moves up and down relative to the connector 230 along the first direction (Z1 / Z2), a portion of the extension 330 can extend into the connector 230 and move up and down relative to the connector 230. Thus, the connector 230 can guide and limit the movement of the extension 330, preventing it from jamming during the movement and improving the stability of the cover 300 relative to the base 200. It is understood that the projection of the extension 330 onto the base 210 is located within the connector 230, ensuring that a portion of the extension 330 can extend into the connector 230, thereby enabling the extension 330 to move up and down relative to the connector 230.

[0065] More specifically, in some embodiments, the base 210 includes a base body 211 and a top cover 213 connected together, and the rechargeable battery 400 and circuit board 500 are both disposed inside the base 210. The base body 211 and the top cover 213 are detachably connected, which facilitates the installation of the rechargeable battery 400 and the circuit board 500.

[0066] A movable connection refers to a connection method between two or more components that allows relative movement between the connected components. In some embodiments of this application, the cover 300 and the base 210 are movably connected, meaning that the cover 300 and the base 210 can rotate relative to each other, slide relative to each other, or rise relative to each other. Thus, when the cover 300 moves relative to the base 210, the cover 300 can switch between a pressed position and a released position. Specifically, when the cover 300 is in the pressed position, it can press the earphone 2000, at which time the earphone 2000 can be stored in the charging case 1000; when the cover 300 is in the released position, it can release the earphone 2000, at which time the earphone 2000 can be removed from the charging case 1000.

[0067] The base 210 has at least one through hole 600, which connects the interior and exterior of the charging case 1000. The through hole 600 can be located at any position on the base 210; that is, the base body 211, the top cover 213, and the connector 230 can all have through holes 600. The cross-sectional shape of the through hole 600 can be circular, elliptical, triangular, quadrilateral, or other polygonal shapes, etc., and is not limited herein. In one example, there may be one through hole 600. In another example, there may be at least two through holes 600. In embodiments with multiple through holes 600, the cross-sectional shapes of the multiple through holes 600 can be the same or different. In one example, the through hole 600 can house both components located inside the base 210 and external components; that is, the through hole 600 can serve as a connection channel between components located inside the base 210 and external components. For example, the through-hole 600 can serve as a charging port, allowing an external data cable to extend into it and connect to the data exchange terminal 260 within the through-hole 600 for data transmission and / or charging of the charging case 1000. In another example, components can be partially housed inside the base 210 and partially extend through the through-hole 600 to the external environment. For instance, the through-hole 600 can house components such as a button structure 700 and an indicator light assembly 800. A portion of the button structure 700 is located within the base 210, while another portion extends outside the base 210. The user can retract the button structure 700 into the through-hole 600 by pressing it.

[0068] A sealing assembly 100 is disposed on a seat 210 and serves to prevent external flow from entering the interior of the seat 210 through the through-hole 600. The sealing assembly 100 includes at least one sealing element, the material of which is not limited to metal, plastic, or rubber, etc., and is not limited in this application. The cross-sectional shape of the sealing element may be circular, elliptical, triangular, quadrilateral, or other polygonal, etc., and is not limited herein. In one example, the sealing assembly 100 may have one sealing element. In another example, the sealing assembly 100 may have at least two sealing elements. In embodiments with multiple sealing elements, the cross-sectional shapes of the multiple sealing elements may be the same or different.

[0069] The sealing assembly 100 can directly block the through hole 600. That is, in embodiments where there are no other components in the through hole 600, the sealing assembly 100 can seal all the space inside the through hole 600 to prevent external fluid from entering the seat 210 through the through hole 600. In embodiments where there are components in the through hole 600, the sealing element can be disposed on the outer wall of the through hole 600 and cooperate with the component disposed in the through hole 600 to seal the gap between the inner wall of the through hole 600 and the outer wall of the component in the through hole 600 to prevent external fluid from entering the seat 210 through the through hole 600. The sealing element can be disposed on the outer wall of the component in the through hole 600 and then inserted into the through hole 600 together with the component to seal the gap between the inner wall of the through hole 600 and the outer wall of the component in the through hole 600 to prevent external fluid from entering the seat 210 through the through hole 600.

[0070] In an embodiment where the sealing component 100 is disposed on the outer wall of the element in the through hole 600, the sealing component 100 may be separately molded and then fitted onto the element in the through hole 600, or it may be fitted onto the outer wall of the element in the through hole 600 in the form of overmolding or the like, or it may be directly molded onto the outer wall of the element in the through hole 600 through a two-color injection molding process. In this case, the materials of the element in the through hole 600 and the sealing component 100 may be the same or different.

[0071] The charging case 1000 of this application can prevent external fluids from entering the interior of the base 210 through the through hole 600 by providing a sealing component 100 on the base 210, thereby further enhancing waterproofing and preventing external fluids from damaging the internal structure of the base 210, thus ensuring the normal operation of the charging case 1000.

[0072] Please see Figure 4 and Figure 5 In some embodiments, the through hole 600 includes a first through hole 610 for mounting a pressing member 710 movable relative to the seat 210. The first through hole 610 is located on the side wall of the seat 210. The sealing assembly 100 includes a blocking member 10, the opposite ends of which are connected to the side wall of the seat 210 to divide the seat 210 into a first cavity 2051 and a second cavity 2053. The first cavity 2051 communicates with the first through hole 610.

[0073] Specifically, the charging case 1000 also includes a button structure 700. The button structure 700 includes a pressing member 710, a mating member 720, and a resetting member 730. The pressing member 710 achieves reciprocating motion in the first through hole 610 through its mating with the mating member 720 and the resetting member 730.

[0074] The shape and size of the cross-section of the pressing member 710 cut by a plane perpendicular to the second direction (X1 / X2) are approximately the same as the shape and size of the cross-section of the first through hole 610 cut by a plane perpendicular to the second direction (X1 / X2). This not only ensures that the pressing member 710 can slide relative to the seat 210 within the first through hole 610 when pressed, but also reduces the gap between the pressing member 710 and the inner wall of the first through hole 610. This reduces or even prevents external water or dust from entering the base 200 through the gap between the pressing member 710 and the first through hole 610, thereby ensuring the normal operation of the structures inside the base 200 (such as the rechargeable battery 400 and the circuit board 500).

[0075] A blocking member 10 is disposed on the bottom wall of the base 200, and the blocking member 10 includes a blocking body 11 and two connecting portions 13 located at opposite ends of the blocking body 11. The connecting portions 13 are connected to the inner side of the side wall of the base 200, and the blocking body 11 is spaced apart from the side wall of the base 200 in the second direction (X1 / X2). One end of the reset member 730 is connected to the blocking body 11, and the other end is connected to the mating member 720. Thus, when the mating member 720 moves from the locked position to the unlocked position along the second direction (X1 / X2), the reset member 730 can generate a reset force, which can reset the mating member 720 from the unlocked position to the locked position.

[0076] In some embodiments, the first through hole 610 penetrates the side wall of the base 200, thereby improving user convenience, for example, facilitating one-handed operation of the charging case 1000. In other embodiments, the first through hole 610 may also penetrate the bottom wall of the base 200. This reduces the possibility of external water or dust entering the base 200 through the first through hole 610, preventing damage to the internal structure of the base 200 and ensuring the normal operation of the charging case 1000. Furthermore, it allows liquid inside the base 200 to flow out through the first through hole 610, preventing liquid accumulation inside the base 200 from damaging its internal structure. In still other embodiments, the first through hole 610 penetrates both the side wall and the bottom wall of the base 200. This increases the size of the first through hole 610, allowing the user to insert the first through hole 610 into the base 200 to apply the first force to the mating part 720, thus facilitating user operation. On the other hand, it allows liquid inside the base 200 to flow out through the first through hole 610, preventing liquid from accumulating inside the base 200 and causing damage to the structure inside the base 200.

[0077] The base 200 has a receiving cavity 205 for accommodating the rechargeable battery 400 and circuit board 500, etc. The blocking member 10 divides the base 200 into a first cavity 2051 and a second cavity 2053; that is, the blocking member 10 divides the receiving cavity 205 into a first cavity 2051 and a second cavity 2053. The first through hole 610 communicates with the first cavity 2051. The rechargeable battery 400 and circuit board 500, etc., are all housed in the second cavity 2053. Therefore, when external fluid enters the receiving cavity 205 through the first through hole 610, the blocking member 10 can block the external fluid within the first cavity 2051, preventing damage to the rechargeable battery 400 and circuit board 500, etc., thus ensuring the normal operation of the charging box 1000.

[0078] Please continue reading. Figure 4 and Figure 5 In some embodiments, the sealing assembly 100 further includes a first limiting member 31 and a second limiting member 33, which are used to contact the outer wall of the pressing member 710 so that the deflection of the pressing member 710 during movement is within a predetermined range. The first limiting member 31, the second limiting member 33, the blocking member 10, and the side wall of the seat 210 together form a sub-cavity 20511, and the first through hole 610 communicates with the sub-cavity 20511.

[0079] Specifically, the base 200 is provided with a limiting member 30, and the pressing member 710 includes an extension wall 711. The limiting member 30 partially encloses the extension wall 711 to at least limit the extension wall 711 from tilting toward the cover 300. The limiting member 30 is disposed in the first cavity 2051. One end of the limiting member 30 can be connected to the blocking member 10, and the other end can be connected to the side wall of the base 200. The extension wall 711 can be the side wall of the pressing member 710 in a third direction (Y1 / Y2), which is perpendicular to the first direction (Z1 / Z2) and also perpendicular to the second direction (X1 / X2).

[0080] Among them, the limiting member 30 partially encloses the extension wall 711. That is, the shape, size and outline of the side of the limiting member 30 opposite to the extension wall 711 are exactly the same or almost exactly the same as the shape, size and outline of the extension wall 711. In this way, the limiting member 30 can cooperate with the extension wall 711 to prevent the extension wall 711 from tilting towards the cover 300 and causing the movement of the pressing member 710 to deviate. This ensures the stability of the movement of the pressing member 710 and the mating member 720, thereby improving the stability and reliability of the button structure 700.

[0081] Furthermore, the limiting member 30 includes a first limiting member 31 and a second limiting member 33, and the extension wall 711 includes a first extension wall 7111 and a second extension wall 7113. The first limiting member 31 covers at least a portion of the first extension wall 7111 and at least limits the first extension wall 7111 from tilting toward the cover 300. The second limiting member 33 covers at least a portion of the second extension wall 7113 and at least limits the second extension wall 7113 from tilting toward the cover 300.

[0082] The first extension wall 7111 and the second extension wall 7113 can be two opposite sidewalls of the pressing member 710 in a third direction (Y1 / Y2). Compared to the limiting member 30 which only includes the first limiting member 31 or the second limiting member 33, the provision of the first limiting member 31 and the second limiting member 33 can further improve the stability of the pressing member 710 moving along the second direction (X1 / X2), prevent the pressing member 710 from tilting relative to the base 200, improve the stability and reliability of the button structure 700, and ensure that the deflection of the pressing member 710 during movement is within a predetermined range.

[0083] Sub-cavity 20511 is located inside the first cavity 2051. The blocking member 10 can block external fluid in the sub-cavity 20511, preventing external fluid from entering the second cavity 2053 from the sub-cavity 20511, avoiding damage to the rechargeable battery 400 and circuit board 500 in the second cavity 2053, thereby ensuring the normal operation of the charging box 1000.

[0084] Please see Figure 5 and Figure 6 Furthermore, in some embodiments, the through hole 600 may also include a second through hole 620, which is disposed on the side wall of the base 210. The charging box 1000 also includes an indicator light assembly 800, which includes a light guide 810. The sealing assembly 100 includes a first seal 40, and the light guide 810 extends at least partially into the second through hole 620. The first seal 40 is sleeved on the light guide 810 and is located between the outer side wall of the light guide 810 and the inner side wall of the second through hole 620. The first seal 40 is used to seal the gap between the outer side wall of the light guide 810 and the inner side wall of the second through hole 620.

[0085] Specifically, the shape and size of the cross-section of the light guide 810 cut by a plane perpendicular to the third direction (Y1 / Y2) are approximately the same as the shape and size of the cross-section of the second through hole 620 cut by a plane perpendicular to the third direction (Y1 / Y2). This reduces the gap between the light guide 810 and the inner wall of the second through hole 620, reducing or even preventing external water or dust from entering the base 200 through the gap between the light guide 810 and the first through hole 610. This ensures the normal operation of the structures inside the base 200 (such as the rechargeable battery 400 and the circuit board 500).

[0086] The first sealing member 40 is sleeved on the light guide member 810 and located between the outer wall of the light guide member 810 and the inner wall of the second through hole 620, sealing the gap between the outer wall of the light guide member 810 and the inner wall of the second through hole 620. Therefore, when external fluid enters the second through hole 620, the first sealing member 40 can block the external fluid at the part of the second through hole 620 near the outside, preventing external fluid from entering the housing 210 through the second through hole 620 and damaging structures such as the indicator light assembly 800, the rechargeable battery 400, and the circuit board 500, thus ensuring the normal operation of the charging box 1000.

[0087] Please see Figure 3 , Figure 4 and Figure 5 Furthermore, in some embodiments, the through-hole 600 may also include a third through-hole 630, which is disposed on the side wall of the base 210. The charging box 1000 also includes a data exchange terminal 260. The sealing assembly 100 further includes a second seal 50, which is sleeved on the data exchange terminal 260 and located between the outer side wall of the data exchange terminal 260 and the inner side wall of the third through-hole 630. The second seal 50 is used to seal the gap between the outer side wall of the data exchange terminal 260 and the inner side wall of the third through-hole 630.

[0088] Specifically, the shape and size of the cross-section of the data exchange terminal 260 cut by a plane perpendicular to the third direction (Y1 / Y2) are approximately the same as the shape and size of the cross-section of the third through hole 630 cut by a plane perpendicular to the third direction (Y1 / Y2). This reduces the gap between the data exchange terminal 260 and the inner wall of the third through hole 630, reducing or even preventing external water or dust from entering the base 200 through the gap between the data exchange terminal 260 and the third through hole 630. This ensures the normal operation of the structures inside the base 200 (such as the rechargeable battery 400 and the circuit board 500).

[0089] The second sealing element 50 is sleeved on the data exchange terminal 260 and located between the outer wall of the data exchange terminal 260 and the inner wall of the second through hole 620, sealing the gap between the outer wall of the data exchange terminal 260 and the inner wall of the second through hole 620. Therefore, when external fluid enters the third through hole 630, the second sealing element 50 can block the external fluid at the part of the third through hole 630 closest to the outside, preventing external fluid from entering the housing 210 through the third through hole 630 and damaging structures such as the rechargeable battery 400 and circuit board 500, thus ensuring the normal operation of the charging box 1000.

[0090] Please see Figure 5 , Figure 7 and Figure 8Furthermore, in some embodiments, the through hole 600 may also include a fourth through hole 640, which is disposed on the top wall of the base 210. The charging box 1000 also includes a charging terminal 250, one end of which is located inside the base 210, and the other end of which extends out of the through hole 600 to the outside of the base 210. The sealing assembly 100 also includes a third seal 60, which is disposed between the inner sidewall of the fourth through hole 640 and the outer sidewall 251 of the charging terminal 250. The third seal 60 is used to prevent fluid from entering the base 210 from between the inner sidewall of the fourth through hole 640 and the outer sidewall 251 of the charging terminal 250.

[0091] The fourth through-hole 640 connects the interior and exterior of the charging case 1000. The fourth through-hole 640 is located on the top wall of the base 210. The cross-sectional shape (the plane intercepted by the XY plane) of the fourth through-hole 640 can be circular, elliptical, triangular, quadrilateral, or other polygonal, and is not limited thereto. In one example, there may be one fourth through-hole 640, in which a charging terminal 250 is installed. In another example, there may be at least two fourth through-holes 640, in which case one charging terminal 250 is installed in each fourth through-hole 640. This increases the density of the charging terminals 250 and improves the electrical connection stability of the charging case 1000 assembly.

[0092] A charging terminal 250 is installed within the fourth through hole 640 to enable electrical connection between internal components of the charging case 1000 and external components. One end of the charging terminal 250 is located inside the base 210, and the other end extends from the fourth through hole 640 to the outside of the base 210. The end of the charging terminal 250 outside the base 210 is used to connect to the power terminal 2700 to achieve electrical connection with the earphone 2000, while the end of the charging terminal 250 inside the base 210 is used to connect to other components within the charging case 1000. The installation direction of the charging terminal 250 into the fourth through hole 640 is the first direction (Z1 / Z2). There can be one or more charging terminals 250; in this application, there are four charging terminals 250. In other embodiments of this application, the charging terminals 250 can be any other number. The material of the charging terminal 250 can be conductive materials such as copper, aluminum alloy, or nickel. When there are multiple charging terminals 250, the materials of the multiple charging terminals 250 can be different or the same.

[0093] There is a certain difference in size between the fourth through hole 640 and the charging terminal 250, which serves as a reserve size for installation, allowing the charging terminal 250 to be installed inside the fourth through hole 640. Therefore, after the charging terminal 250 is installed in the fourth through hole 640, there is a certain gap between the inner wall of the fourth through hole 640 and the outer wall 251 of the charging terminal 250.

[0094] The third sealing element 60 is disposed between the fourth through hole 640 and the charging terminal 250, and is used to seal the gap between the inner sidewall of the fourth through hole 640 and the outer sidewall 251 of the charging terminal 250 to prevent fluid from flowing into the charging box 1000 through the gap. The third sealing element 60 can be made of various materials such as rubber, silicone, and polypropylene. There can be one or more third sealing elements 60, which is not limited in this application. In the embodiments of this application, the number of third sealing elements 60, the number of charging terminals 250, and the number of fourth through holes 640 are in a one-to-one correspondence.

[0095] The third sealing element 60 can be molded separately and then fitted onto the charging terminal 250, or it can be fitted onto the outer wall 251 of the charging terminal 250 in the form of encapsulation, or it can be directly molded onto the outer wall 251 of the charging terminal 250 through a two-color injection molding process. In this case, the materials of the charging terminal 250 and the third sealing element 60 can be the same or different.

[0096] The third seal 60 is installed in the gap between the inner wall of the fourth through hole 640 and the outer wall 251 of the charging terminal 250 in the charging case 1000. It seals the gap between the inner wall of the fourth through hole 640 and the outer wall 251 of the charging terminal 250, preventing fluid from flowing into the charging case 1000 and improving its waterproof rating. Furthermore, the third seal 60 is low-cost and does not occupy additional installation space.

[0097] Please see Figure 5 and Figure 8 In some embodiments, the third seal 60 and the charging terminal 250 are separate structures. The third seal 60 is sleeved on the outer side wall 251 of the charging terminal 250 and located between the outer side wall 251 of the charging terminal 250 and the inner side wall of the fourth through hole 640.

[0098] The third seal 60 and the charging terminal 250 are separate structures, meaning they are two distinct components. In one example, the third seal 60 and the charging terminal 250 can be detachably connected, including but not limited to snap-fit ​​connections or threaded connections. In another example, the third seal 60 and the charging terminal 250 can be non-detachably connected, including but not limited to adhesive bonding or welding. This separate structure facilitates the replacement of both the third seal 60 and the charging terminal 250.

[0099] Please see Figure 5 and Figure 8In some embodiments, the third seal 60 is a sealing ring.

[0100] Specifically, in an embodiment where the third sealing element 60 is separately formed and fitted onto the charging terminal 250, the third sealing element 60 can be a sealing ring. The sealing ring is fitted onto the outer wall 251 of the charging terminal 250 to seal the gap between the inner wall of the fourth through hole 640 and the outer wall 251 of the charging terminal 250. The sealing ring is easy to replace and has low cost.

[0101] The sealing ring can be made of a material with a certain degree of elasticity, such as rubber. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The elastic sealing ring not only provides waterproofing but also absorbs vibration and impact for the charging terminal 250, preventing deformation of the charging terminal 250 under external forces.

[0102] Please see Figure 5 , Figure 7 and Figure 9 In some embodiments, the third seal 60 and the charging terminal 250 are an integral structure.

[0103] Specifically, the third seal 60 and the charging terminal 250 are an integral structure, that is, the third seal 60 and the charging terminal 250 are a whole structure, which can improve the bonding strength between the third seal 60 and the charging terminal 250, prevent the third seal 60 and the charging terminal 250 from separating during the operation of the charging box 1000, thereby ensuring the stability and reliability of the operation of the charging box 1000, and further improving the sealing and waterproof effect.

[0104] Please see Figure 5 , Figure 7 and Figure 9 In some embodiments, both the third seal 60 and the charging terminal 250 are made of metal.

[0105] Specifically, metals have high strength and good wear resistance, and using metal as the material for the third seal 60 and the charging terminal 250 can extend the service life of both. In embodiments where both the third seal 60 and the charging terminal 250 are made of metal, the metal materials used for the third seal 60 and the charging terminal 250 can be the same or different. For example, it is understood that the material of the charging terminal 250 can be a material with good conductivity to ensure the electrical connection between the charging terminal 250 and the power receiving terminal 2700. The third seal 60 can be a material with good chemical stability, such as copper. Copper has strong rust resistance and will not be corroded by impurities in water, ensuring the waterproof effect of the third seal 60.

[0106] In embodiments where the third seal 60 and the charging terminal 250 are integrally formed and both the third seal 60 and the charging terminal 250 are made of metal, the integrally formed and metal third seal 60 and the charging terminal 250 can form an interference fit with the fourth through hole 640, thereby sealing the gap between the outer sidewall 251 of the charging terminal 250 and the inner sidewall of the fourth through hole 640, achieving a waterproof effect.

[0107] In embodiments where the third sealing element 60 and the charging terminal 250 are integrally formed and both the third sealing element 60 and the charging terminal 250 are made of copper, the integrally formed copper third sealing element 60 and the charging terminal 250 can not only form an interference fit with the fourth through hole 640, thereby sealing the gap between the outer side wall 251 of the charging terminal 250 and the inner side wall of the fourth through hole 640 to achieve a waterproof effect, but also copper has strong conductivity and strong rust resistance, and will not be corroded by impurities in water. This not only ensures the waterproof effect, but also ensures the stability of the connection between the charging terminal 250 and the power connection terminal 2700.

[0108] Please see Figure 4 , Figure 7 ,and Figure 8 or Figure 9 The charging case 1000 also includes a circuit board 500 and an electrical connector 270. The circuit board 500 is housed within the base 210, and the electrical connector 270 is mounted on the circuit board 500 and electrically connected to the charging terminal 250.

[0109] Electrical connector 270 connects charging terminal 250 to circuit board 500. There can be one or more electrical connectors 270. One electrical connector 270 can correspond to multiple charging terminals 250, one electrical connector 270 can correspond to one charging terminal 250, or multiple electrical connectors 270 can correspond to one charging terminal 250. In the embodiment of the application, one electrical connector 270 corresponds to one charging terminal 250. The material of the electrical connector 270 includes, but is not limited to, copper, aluminum, or nickel. The electrical connector 270 has a certain elastic deformation capability, capable of elastic deformation in a first direction (Z1 / Z2), thereby better connecting the charging terminal 250 and circuit board 500. When the charging terminal 250 is inserted into the fourth through hole 640, the charging terminal 250 applies a force in the first direction (Z1 / Z2) to the electrical connector 270. The electrical connector 270 can elastically deform according to the insertion depth of the charging terminal 250 in the first direction (Z1 / Z2) (i.e., the distance between the charging terminal 250 and the circuit board 500), thereby allowing the electrical connector 270 to fit better with the charging terminal 250. That is, the electrical connector 270 can adjust its elastic deformation according to the distance between the charging terminal 250 and the circuit board 500, thereby ensuring the stability of the electrical connection between the charging terminal 250 and the circuit board 500.

[0110] After the charging terminal 250 is installed into the fourth through hole 640, if the charging terminal 250 is subjected to a force in the first direction (Z1 / Z2) and moves towards the circuit board 500, the electrical connector 270 can provide an opposite force and isolate the charging terminal 250 and the circuit board 500, preventing the charging terminal 250 from directly pressing the circuit board 500 and causing damage to the circuit board 500. After the charging terminal 250 is installed into the fourth through hole 640, if the charging terminal 250 is subjected to a force opposite to the first direction (Z1 / Z2), causing the distance between the charging terminal 250 and the circuit board 500 in the first direction (Z1 / Z2) to increase, the electrical connector 270 can recover some of its elastic deformation and continue to maintain an electrical connection with the charging terminal 250, thereby ensuring the stability of the electrical connection between the charging terminal 250 and the circuit board 500.

[0111] Electrical connector 270 is mounted on circuit board 500 and electrically connected to charging terminal 250. Electrical connector 270 can adapt to different distances between charging terminal 250 and circuit board 500 through elastic deformation, thereby maintaining a stable electrical connection between the charging terminal 250 and circuit board 500. Furthermore, using electrical connector 270 avoids the need for SMT (Surface Mount Technology) processes to connect charging terminal 250 and circuit board 500, saving costs.

[0112] Please see Figure 4 , Figure 7 ,and Figure 8 or Figure 9 In some embodiments, the electrical connector 270 includes a conductive body 271 and a conductive spring 273. The conductive body 271 is mounted on the circuit board 500. The conductive spring 273 extends from the conductive body 271 in a direction away from the circuit board 500 and then bends back in a direction close to the circuit board 500 to form a protrusion 2731. The protrusion 2731 abuts against the charging terminal 250.

[0113] Specifically, the conductive spring 273 has a certain elastic deformation capability, and can elastically deform in the first direction (Z1 / Z2) to better contact the charging terminal 250, thereby better connecting the charging terminal 250 and the circuit board 500. The conductive body 271 is mounted on the circuit board 500 to ensure a stable connection between the electrical connector 270 and the circuit board 500, making it difficult for the electrical connector 270 to fall off the circuit board 500.

[0114] In the embodiments of this application, the conductive body 271 and the conductive spring 273 are an integral structure, that is, the conductive body 271 and the conductive spring 273 are a single unit. This improves the bonding strength between the conductive body 271 and the conductive spring 273, preventing separation of the conductive body 271 and the conductive spring 273 during the operation of the electrical connector 270, thereby ensuring the stability and reliability of the electrical connector 270. In other embodiments, the conductive body 271 and the conductive spring 273 are separate structures, that is, the conductive body 271 and the conductive spring 273 are two different structures.

[0115] In one example, the conductive body 271 and the conductive spring 273 can be detachably connected, including but not limited to snap-fit ​​connections or threaded connections. In another example, the conductive body 271 and the conductive spring 273 can be non-detachably connected, including but not limited to bonding or welding. The protrusion 2731 abuts against the charging terminal 250 and has a certain degree of elasticity; that is, the conductive spring 273 can elastically deform in the first direction (Z1 / Z2) to change its relative position with the charging terminal 250, adapting to different relative positions to ensure electrical connection with the charging terminal 250, thereby making the connection between the electrical connector 270 and the charging terminal 250 more stable.

[0116] Please see Figure 4 , Figure 7 ,and Figure 8 or Figure 9 In some embodiments, the outer surface of the top wall of the base 210 is curved, there are multiple charging terminals 250 and multiple electrical connectors 270, and at least two electrical connectors 270 have different contact positions with the corresponding charging terminals 250 at different heights relative to the circuit board 500 so that the end faces of the other ends of the multiple charging terminals 250 are flush.

[0117] Specifically, in some embodiments, the outer surface of the charging case 1000 is curved, that is, the outer surface of the charging case 1000 is not planar, which allows the outer surface of the charging case 1000 to adapt to different environments, such as being compatible with earphones 2000 of different shapes and contours. The outer surfaces of the multiple charging terminals 250 are flush with each other, which allows for good electrical connection with the power terminals 2700 on the earphones 2000. Furthermore, the distance between the outer surfaces of the multiple charging terminals 250 and the outer surface of the charging case 1000 is the same, which allows the outer surface of the charging case 1000 to be flat and prevents the charging terminals 250 from protruding and being bumped.

[0118] Please see Figure 4 and Figure 5In some embodiments, the seat 210 further includes a seat body 211 and a top cover 213. The top of the seat body 211 is provided with a fifth through hole 650, and the top cover 213 covers the fifth through hole 650. The sealing assembly 100 further includes a fourth sealing member 70, which is disposed on the top of the seat body 211 and located between the seat body 211 and the top cover 213. The fourth sealing member 70 is used to seal the gap between the seat body 211 and the top cover 213.

[0119] The base body 211 and the top cover 213 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. In another example, the base body 211 and the top cover 213 can be joined together by a non-detachable connection method, including but not limited to adhesive bonding or welding.

[0120] The fourth sealing element 70 is disposed on the top of the base body 211 and located between the base body 211 and the upper cover 213. Therefore, when external fluid enters the fifth through hole 650, the fourth sealing element 70 can block the external fluid from entering the base body 210 through the portion of the fifth through hole 650 that communicates with the outside, preventing external fluid from damaging the rechargeable battery 400 and circuit board 500, thus ensuring the normal operation of the charging box 1000.

[0121] Please continue reading. Figure 4 and Figure 5 In some embodiments, the fourth seal 70 is a sealing ring.

[0122] Specifically, in the embodiment where the fourth seal 70 is molded separately, the fourth seal 70 can be a sealing ring. The fourth seal 70 is disposed on the top of the seat body 211 and located between the seat body 211 and the upper cover 213. The fourth seal 70 is used to seal the gap between the seat body 211 and the upper cover 213. The sealing ring is easy to replace and has low cost.

[0123] The sealing ring can be made of a material with a certain degree of elasticity, such as rubber. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The elastic sealing ring not only provides waterproofing but also absorbs vibration and impact for the charging terminal 250, preventing deformation of the charging terminal 250 under external forces.

[0124] Please continue reading. Figure 4 and Figure 5In some embodiments, the fourth seal 70 is a sealant. Specifically, in embodiments where the fourth seal 70 is a sealant, the sealant is easy to apply. After the sealant is applied directly to the seat body 211 and / or the top cover 213, the seat body 211 and the top cover 213 can be directly closed and connected without an alignment process, making installation simple.
