In another example, in the case where the earphone 2000 is an air conduction earphone 2000, the transducing assembly 2100 is configured to at least partially extend into at least one of the concha cavity, the cymba concha, the triangular fossa, etc. when the earphone 2000 is in the wearing state. It is to be noted that the following embodiments are described only by way of example with the earphone 2000 being a bone conduction earphone 2000.

[0037] Further, in some embodiments, the earphone 2000 includes a battery compartment 2200, a control compartment 2300, a first ear-hanging assembly 2400, a second ear-hanging assembly 2500, and a rear-hanging assembly 2600 disposed between the first ear-hanging assembly 2400 and the second ear-hanging assembly 2500. The first ear-hanging assembly 2400 and the second ear-hanging assembly 2500 are respectively hung on the left ear and the right ear. The battery compartment 2200 can be disposed between the first ear-hanging assembly 2400 and the rear-hanging assembly 2600, and the control compartment 2300 can be disposed between the second ear-hanging assembly 2500 and the rear-hanging assembly 2600. The first transducing assembly 2101 and the second transducing assembly 2103 are both used to convert electrical signals into mechanical vibrations to enable the user to hear sound. Among them, the first transducing assembly 2101 and the second transducing assembly 2103 are both located at the front side of the ear when the earphone 2000 is in the wearing state.

[0038] Please refer to Figure 1 and Figure 4 In some embodiments, the charging box 1000 includes a charging battery 400 and a circuit board 500, which can deliver the electrical energy of the charging battery 400 to the earphone 2000 to achieve charging of the earphone 2000 when the earphone 2000 is placed in the charging box 1000.

[0039] Further, please refer to Figure 2 and Figure 3In some embodiments, the charging case 1000 is provided with first electrical connectors, and the earphone 2000 is provided with second electrical connectors. In some embodiments, the first electrical connectors can be at least one of spring pins, spring sheets and other devices capable of electrical connection; the second electrical connectors can be devices capable of electrical connection with the first electrical connectors. In the embodiments of the present application, the first electrical connectors are charging terminals 250, and the second electrical connectors are electrical connection terminals 2700. When the earphone 2000 is placed in the charging case 1000, the charging terminals 250 and the electrical connection terminals 2700 are electrically connected.

[0040] Specifically, in some embodiments, when the charging terminals 250 and the electrical connection terminals 2700 are electrically connected, the charging case 1000 and the earphone 2000 can realize functions such as electrical energy transmission and data transmission. For example, when the charging terminals 250 and the electrical connection terminals 2700 are electrically connected, the circuit board 500 can transmit electrical energy of the charging battery 400 to the battery compartment 2200 of the earphone 2000 through the charging terminals 250 and the electrical connection terminals 2700, thereby charging the earphone 2000.

[0041] Further, in some embodiments, the charging terminals 250 include a plurality of charging terminals, and the electrical connection terminals 2700 include a plurality of electrical connection terminals. When the earphone 2000 is placed in the charging case 1000, the plurality of charging terminals 250 and the plurality of electrical connection terminals 2700 are electrically connected one by one.

[0042] Specifically, in some embodiments, a part of the plurality of charging terminals 250 is used for electrical energy transmission, and another part is used for signal transmission; correspondingly, a part of the plurality of electrical connection terminals 2700 is used for electrical energy transmission, and another part is used for signal transmission. Among them, the plurality of charging terminals 250 are arranged side by side on the charging case 1000. In this way, compared with the non-side-by-side arrangement of the plurality of charging terminals 250 on the charging case 1000, on the one hand, it can reduce the space occupied by the charging terminals 250, make the structure more compact, and be beneficial to the miniaturization of the charging case 1000; on the other hand, it can facilitate the alignment of the charging terminals 250 and the electrical connection terminals 2700, and improve the convenience of electrical connection.

[0043] Please refer to Figure 3 , Figure 4 and Figure 6The charging box 1000 provided by the embodiments of the present application comprises a sealing member 100, a seat body 210 and a charging terminal 250. The seat body 210 is provided with at least one through hole 600. The charging terminal 250 is arranged on the seat body 210, one end of the charging terminal 250 is located in the seat body 210, and the other end of the charging terminal 250 extends out of the seat body 210 from the through hole 600. The sealing member 100 is arranged between the inner side wall 601 of the through hole 600 and the outer side wall 251 of the charging terminal 250, and the sealing member 100 is used to block the fluid from entering the seat body 210 from between the inner side wall 601 of the through hole 600 and the outer side wall 251 of the charging terminal 250.

[0044] Specifically, referring to Figure 3 and Figure 4 , the charging box 1000 comprises a base 200 and a cover 300. The base 200 comprises a seat body 210 and a connecting member 230, and the base 200 is a structure used to carry the earphone 2000 in the charging box 1000. In some embodiments of the present application, the charging battery 400 and the circuit board 500 are arranged in the base 200, so that the weight of the base 200 is relatively large, and the possibility of the charging box 1000 being tilted when the earphone 2000 is stored in the charging box 1000 is reduced. The material of the base 200 comprises but is not limited to plastic, aluminum alloy, copper, iron, steel and carbon fiber composite material, etc. Exemplarily, the material of the base 200 is plastic, so that the charging box 1000 is more portable and convenient for users to carry.

[0045] The cover 300 is a structure capable of cooperating with the base 200 to limit the earphone 2000 in the charging box 1000. In some embodiments of the present application, the projection of the cover 300 in the vertical direction of the height of the charging box 1000 coincides with the projection of the base 200 in the vertical direction of the height of the charging box 1000; or, the projection of the cover 300 in the vertical direction of the height of the charging box 1000 is located in the projection of the base 200 in the vertical direction of the height of the charging box 1000. The material of the cover 300 comprises but is not limited to plastic, aluminum alloy, copper, iron, steel and carbon fiber composite material, etc. Exemplarily, the material of the cover 300 is plastic, so that the charging box 1000 is more portable and convenient for users to carry. It can be understood that the material of the cover 300 and the material of the base 200 can be the same or different.

[0046] The cover 300 comprises a main body 310 and an extending member 330, the extending member 330 extends from the main body 310 to the base 200, the base 200 comprises the seat body 210 and the connecting member 230, the connecting member 230 extends from the seat body 210 to the cover 300, the extending member 330 partially extends into the connecting member 230 and can be lifted relative to the connecting member 230 to switch the cover 300 between the pressing position and the releasing position.

[0047] Specifically, in some embodiments, the part of the extension member 330 can extend into the connecting member 230 and can be lifted relative to the connecting member 230, so that the connecting member 230 can guide and limit the lifting of the extension member 330, preventing the extension member 330 from being stuck during lifting, thereby improving the stability of the lifting of the cover body 300 relative to the base 200. It can be understood that the projection of the extension member 330 on the seat body 210 is located in the connecting member 230, so as to ensure that the part of the extension member 330 can extend into the connecting member 230, and thus the extension member 330 can be lifted relative to the connecting member 230.

[0048] More specifically, in some embodiments, the seat body 210 includes a seat body 211 and an upper cover 213 connected to each other, and the charging battery 400 and the circuit board 500 are arranged in the seat body 210. Among them, the seat body 211 and the upper cover 213 are detachably connected, so as to facilitate the installation of the charging battery 400 and the circuit board 500.

[0049] The movable connection refers to a connection between two or more components, which allows relative movement between the connected components. In some embodiments of the present application, the cover body 300 is movably connected to the seat body 210, that is, the cover body 300 and the seat body 210 can be relatively rotated, slid or lifted, so that the cover body 300 can be switched between the pressing position and the releasing position when the cover body 300 moves relative to the seat body 210. Among them, when the cover body 300 is in the pressing position, the cover body 300 can press the earphone 2000, and at this time, the earphone 2000 can be stored in the charging box 1000; when the cover body 300 is in the releasing position, the cover body 300 can release the earphone 2000, and at this time, the earphone 2000 can be taken out of the charging box 1000.

[0050] The charging box 1000 is provided with a through hole 600, which communicates the inside and outside of the charging box 1000. The through hole 600 is arranged at any position of the charging box 1000, that is, the seat body 211, the upper cover 213, the connecting member 230, the main body 310 and the extension member 330 can all be provided with the through hole 600. The cross-sectional shape of the through hole 600 can be circular, elliptical, triangular, quadrilateral or other polygonal shape, which is not limited herein. In one example, the number of through holes 600 can be one, and the charging terminal 250 is arranged in the through hole 600. In another example, the number of through holes 600 can be at least two, and each through hole 600 is provided with a charging terminal 250, thereby increasing the density of the charging terminal 250 and improving the electrical connection stability of the components of the charging box 1000. In other embodiments, the through hole 600 can also be provided with elements such as indicator lights and keys.

[0051] The charging terminal 250 is arranged in the through hole 600, and is used to realize electrical connection between internal elements of the charging box 1000 and external elements of the charging box 1000. One end of the charging terminal 250 is located in the seat body 210, and the other end of the charging terminal 250 extends out of the seat body 210 from the through hole 600. The end of the charging terminal 250 located outside the seat body 210 is used to connect the power terminal 2700 to realize connection with the earphone 2000, and the end of the charging terminal 250 located in the seat body 210 is used to connect with other elements of the charging box 1000. The mounting direction of the charging terminal 250 arranged in the through hole 600 is the first direction (Z1 / Z2). The charging terminal 250 can be one or multiple, and in the present application, the charging terminal 250 is four, and in other embodiments of the present application, the charging terminal 250 can be any other number. The material of the charging terminal 250 can be a conductive material such as copper, aluminum alloy or nickel. When the charging terminal 250 is multiple, the materials of the multiple charging terminals 250 can be different or the same.

[0052] In some embodiments, there is a certain difference between the size of the through hole 600 and the size of the charging terminal 250, which is a reserved size during installation, so that the charging terminal 250 can be arranged in the through hole 600. Therefore, after the charging terminal 250 is arranged in the through hole 600, there is a certain gap between the inner side wall 601 of the through hole 600 and the outer side wall 251 of the charging terminal 250.

[0053] The sealing element 100 is arranged between the through hole 600 and the charging terminal 250, and is used to seal the gap between the inner side wall 601 of the through hole 600 and the outer side wall 251 of the charging terminal 250, so as to avoid fluid flowing into the charging box 1000 from the gap. The sealing element 100 can be made of rubber, silicone, polypropylene or other materials. The sealing element 100 can be one or multiple, which is not limited in the present application. In the embodiments of the present application, the number of the sealing element 100, the number of the charging terminal 250 and the number of the through hole 600 are corresponding. The sealing element 100 can be separately formed and sleeved on the charging terminal 250, or can be sleeved on the outer side wall 251 of the charging terminal 250 in the form of encapsulation, or can be directly formed on the outer side wall 251 of the charging terminal 250 through a two-color injection molding process. At this time, the materials of the charging terminal 250 and the sealing element 100 can be the same or different.

[0054] The sealing element 100 is arranged in the gap between the inner side wall 601 of the through hole 600 and the outer side wall 251 of the charging terminal 250 of the charging box 1000, can seal the gap between the inner side wall 601 of the through hole 600 and the outer side wall 251 of the charging terminal 250, prevent fluid from flowing into the charging box 1000 from the gap, and improve the waterproof level of the charging box 1000. In addition, the sealing element 100 has low cost and does not occupy additional installation space.

[0055] Please see Figure 4 and Figure 5 In some embodiments, the seal 100 and the charging terminal 250 are separate structures. The seal 100 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 601 of the through hole 600.

[0056] The seal 100 and the charging terminal 250 are separate structures, meaning they are two distinct components. In one example, the seal 100 and the charging terminal 250 can be detachably connected, including but not limited to snap-fit ​​connections or threaded connections. In another example, the seal 100 and the charging terminal 250 can be non-detachably connected, including but not limited to adhesive bonding or welding. The separate structure of the seal 100 and the charging terminal 250 facilitates the replacement of both.

[0057] Please see Figure 5 and Figure 6 In some embodiments, the seal 100 is a sealing ring.

[0058] Specifically, in an embodiment where the seal 100 is separately molded and fitted onto the charging terminal 250, the seal 100 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 601 of the through hole 600 and the outer wall 251 of the charging terminal 250. The sealing ring is easy to replace and has low cost.

[0059] 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.

[0060] Please see Figure 5 and Figure 7 In some embodiments, the seal 100 and the charging terminal 250 are an integral structure.

[0061] Specifically, the sealing member 100 and the charging terminal 250 are in an integrated structure, that is, the sealing member 100 and the charging terminal 250 are in an integral structure, thereby being capable of improving the bonding strength between the sealing member 100 and the charging terminal 250, preventing the sealing member 100 and the charging terminal 250 from being separated 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.

[0062] Referring to Figure 5 and Figure 7 In some embodiments, the sealing member 100 and the charging terminal 250 are both made of metal.

[0063] Specifically, metal has high strength and good wear resistance, and using metal as the material of the sealing member 100 and the charging terminal 250 can prolong the service life of the sealing member 100 and the charging terminal 250. In the embodiments in which the sealing member 100 and the charging terminal 250 are both made of metal, the metal materials used for the sealing member 100 and the charging terminal 250 can be the same or different. For example, it can be understood that the material of the charging terminal 250 can be a material with good electrical conductivity to ensure the electrical connection between the charging terminal 250 and the electrical connection terminal 2700. The sealing member 100 can be a material with good chemical stability, such as copper, which has strong anti-rust ability and will not be corroded by impurities in water, thereby ensuring the waterproof effect of the sealing member 100.

[0064] In the embodiments in which the sealing member 100 and the charging terminal 250 are in an integrated structure and the sealing member 100 and the charging terminal 250 are both made of metal, the sealing member 100 and the charging terminal 250, which are integrally formed and made of metal, can form an interference fit with the through hole 600, thereby sealing the gap between the outer side wall 251 of the charging terminal 250 and the inner side wall 601 of the through hole 600, and achieving the waterproof effect.

[0065] In the embodiments in which the sealing member 100 and the charging terminal 250 are in an integrated structure and the sealing member 100 and the charging terminal 250 are both made of copper, the sealing member 100 and the charging terminal 250, which are integrally formed and made of copper, not only can form an interference fit with the through hole 600, thereby sealing the gap between the outer side wall 251 of the charging terminal 250 and the inner side wall 601 of the through hole 600, and achieving the waterproof effect, but also have strong electrical conductivity and strong anti-rust ability, and will not be corroded by impurities in water, thereby not only ensuring the waterproof effect, but also ensuring the stability of the connection between the charging terminal 250 and the electrical connection terminal 2700.

[0066] Referring to Figure 4 , Figure 5 , and Figure 6 or Figure 7In some embodiments, the charging case 1000 further comprises a circuit board 500 and electrical connectors 270, the circuit board 500 is accommodated in the seat body 210, and the electrical connectors 270 are mounted on the circuit board 500 and electrically connected with the charging terminals 250.

[0067] The electrical connectors 270 can connect the charging terminals 250 and the circuit board 500. The electrical connectors 270 can be one or more. 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 embodiments 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, nickel, etc. The electrical connector 270 has a certain elastic deformation capacity and can be elastically deformed in the first direction (Z1 / Z2), so as to better connect the charging terminal 250 and the circuit board 500. When the charging terminal 250 is installed into the through hole 600, the charging terminal 250 will exert a force in the first direction (Z1 / Z2) on the electrical connector 270, and 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), so as to make the electrical connector 270 better fit the charging terminal 250. That is, the electrical connector 270 can adjust its elastic deformation degree according to the distance between the charging terminal 250 and the circuit board 500, so as to ensure the stability of the electrical connection between the charging terminal 250 and the circuit board 500.

[0068] After the charging terminal 250 is installed into the through hole 600, if the charging terminal 250 is subjected to a force in the first direction (Z1 / Z2) and approaches the circuit board 500. The electrical connector 270 can provide an opposite force and isolate the charging terminal 250 and the circuit board 500, so as to avoid the charging terminal 250 directly pressing the circuit board 500 and causing damage to the circuit board 500. After the charging terminal 250 is installed into the through hole 600, if the charging terminal 250 is subjected to a force opposite to the first direction (Z1 / Z2) and the distance between the charging terminal 250 and the circuit board 500 in the first direction (Z1 / Z2) becomes far, the electrical connector 270 can recover part of the elastic deformation and continue to maintain electrical connection with the charging terminal 250, so as to ensure the stability of the electrical connection between the charging terminal 250 and the circuit board 500.

[0069] The electric connector 270 is mounted on the circuit board 500 and electrically connected with the charging terminal 250. The electric connector 270 can be elastically deformed to adapt to the different distance between the charging terminal 250 and the circuit board 500, so as to keep the stable electrical connection between the charging terminal 250 and the circuit board 500. In addition, the electric connector 270 can avoid the SMT process to connect the charging terminal 250 and the circuit board 500, thereby saving the cost.

[0070] Please refer to Figure 4 、 Figure 5 , and Figure 6 or Figure 7 In some embodiments, the electric connector 270 includes a conductive body 271 and a conductive spring piece 273. The conductive body 271 is mounted on the circuit board 500, and the conductive spring piece 273 extends from the conductive body 271 away from the circuit board 500, then bends back to approach the circuit board 500 and forms a protruding part 2731, and the protruding part 2731 abuts against the charging terminal 250.

[0071] Specifically, the conductive spring piece 273 has a certain elastic deformation capability, and can be elastically deformed in the first direction (Z1 / Z2), so as to better abut against 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, which can ensure the stable connection between the electric connector 270 and the circuit board 500, so that the electric connector 270 is not easy to fall off from the circuit board 500.

[0072] In the embodiments of the present application, the conductive body 271 and the conductive spring piece 273 are an integral structure, that is, the conductive body 271 and the conductive spring piece 273 are an integral structure, thereby improving the bonding strength between the conductive body 271 and the conductive spring piece 273, preventing the conductive body 271 and the conductive spring piece 273 from being separated during the operation of the electric connector 270, thereby ensuring the stability and reliability of the operation of the electric connector 270. In other embodiments, the conductive body 271 and the conductive spring piece 273 are a split structure, that is, the conductive body 271 and the conductive spring piece 273 are two different structures.

[0073] In one example, the electrically-conductive body 271 and the electrically-conductive spring 273 are combined together by a detachable connection mode, which includes but is not limited to a buckle connection or a threaded connection, etc. In another example, the electrically-conductive body 271 and the electrically-conductive spring 273 are combined together by a non-detachable connection mode, which includes but is not limited to adhesion or welding, etc. The protrusion 2731 is in contact with the charging terminal 250 and has a certain elasticity, i.e., the electrically-conductive spring 273 can be elastically deformed in the first direction (Z1 / Z2) to change the relative position of itself and the charging terminal 250, so as to adapt to the different clamping parts relative to the electrically-conductive spring 273, ensure the electrical connection with the charging terminal 250, and thus make the connection of the electric connector 270 and the charging terminal 250 more stable.

[0074] Please refer to Figure 4 , Figure 5 , and Figure 6 or Figure 7 In some embodiments, the outer side surface of the top wall of the seat body 210 is curved, the charging terminals 250 are multiple, and the electric connectors 270 are multiple. The contact positions of at least two electric connectors 270 and corresponding charging terminals 250 are different in height relative to the circuit board 500, so that the end surfaces of the other ends of the multiple charging terminals 250 are flush.

[0075] Specifically, in some embodiments, the outer side surface of the charging box 1000 is curved, i.e., the outer side surface of the charging box 1000 is not planar, which can adapt the outer side surface of the charging box 1000 to different environments, for example, can be adapted to earphones 2000 with different outer profiles. The outer side surfaces of the multiple charging terminals 250 are flush, which can be well electrically connected with the electric terminals 2700 on the earphones 2000. Further, the distances from the outer side surfaces of the multiple charging terminals 250 to the outer side surface of the charging box 1000 are the same, which can make the outer surface of the charging box 1000 flat, avoiding the charging terminals 250 from protruding and being knocked.

[0076] Please refer to Figure 1 , Figure 4 , and Figure 5 In some embodiments, the top wall of the seat body 210 is provided with a profiling groove 2018, the through hole 600 is in communication with the profiling groove 2018, the other end of the charging terminal 250 extends from the through hole 600 into the profiling groove 2018, and the shape of the profiling groove 2018 matches the outer profile shape of the earphone 2000 to be charged.

[0077] Specifically, in some embodiments, the cover 300 and the base 200 jointly form an earphone compartment 201 for accommodating the earphone 2000. In a plane perpendicular to the height direction of the charging box 1000 (i.e., the first direction (Z1 / Z2)), the earphone compartment 201 includes a first side 2011, a second side 2013, a third side 2015 and a fourth side 2017 in sequence. At least one of the first side 2011 of the earphone compartment, the second side 2013 of the earphone compartment, the third side 2015 of the earphone compartment 201 and the fourth side 2017 of the earphone compartment 201 is open. In this way, when the cover 300 is raised relative to the base 200, the earphone to be charged (the earphone 2000) can be put into the earphone compartment 201 through the open side (including at least one of the first side 2011 of the earphone compartment 201, the second side 2013 of the earphone compartment 201, the third side 2015 of the earphone compartment 201 and the fourth side 2017 of the earphone compartment 201), so that the charging box 1000 can charge and store the earphone 2000.

[0078] The earphone compartment 201 includes a profiling groove 2018 provided on the top wall of the base 210. The profiling groove 2018 is shaped to match the outer contour of the earphone 2000, which can improve the fit of the earphone 2000 and the top wall of the base 210, thereby improving the space utilization of the earphone compartment 201 and facilitating the reduction of the size of the entire charging box 1000. The other end of the charging terminal 250 extends from the through hole 600 into the profiling groove 2018 to connect the power terminal 2700 of the earphone 2000, which can charge the earphone 2000 when the earphone 2000 is put into the earphone compartment 201.
