[0029] Wireless earphones have captured a significant market share in the earphone industry due to their portability and lightweight design. Earphones are typically housed in a portable charging case and charged via the case. Generally, the charging case includes a base and a lid that fit together. The user manually flips the lid to retrieve the earphones, which are at least partially housed in the base and sandwiched between the base and lid. However, this method of removing the earphones from the charging case with one hand is inconvenient and monotonous. To address these issues, this application provides a charging case 100 (see reference...). Figures 1 to 3 ) and headphone system 1000 (please refer to) Figure 4 and Figure 5 ).

[0030] Please refer to Figure 4 and Figure 5 The headphone system 1000 provided in this application includes headphones 300 and a charging case 100. The charging case 100 is used to charge the headphones 300.

[0031] It is understood that the charging case 100 is a device in the headphone system 1000 used to charge or store the headphones 300. For example, when the headphones 300 have low battery or are not needed, the user can place them in the charging case 100. The charging case 100 can be a fixed power source type charging case, in which case the charging case 100 needs to be electrically connected to the power grid or power supply device to deliver electrical energy from the power grid or power supply device to the headphones 300. The charging case 100 can also be a portable power source type charging case, in which case the charging case 100 has a built-in rechargeable energy storage device (not shown), and during the charging process of the charging case 100 charging the headphones 300, the electrical energy of the energy storage device is delivered to the power supply device 3303 in the headphones 300. This application uses a portable power source type charging case as an example for explanation.

[0032] The earphone 300 can be worn on a user's ear and can be used 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. In some embodiments of this application, the earphone 300 is an in-ear earphone, which includes a positioning component 330 and a transducer component 310. The positioning component 330 includes a positioning element 3301 and a power supply element 3303, with the power supply element 3303 disposed within the positioning element 3301. In the wearing state, the transducer component 310 is located within the concha of the ear, and the positioning element 3301 is suspended in front of the user's ear near the concha, reducing the possibility of the earphone 300 falling out during wear.

[0033] It should be noted that, in some embodiments, the power supply component 3303 can be a rechargeable battery, including but not limited to lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries. The ear hook 3301 may be provided with a conductive element, and the power supply component 3303 can be electrically connected to the transducer assembly 310 through the conductive element to supply power to the transducer assembly 310. The conductive element can be spring steel, titanium wire, etc., and this application does not impose any limitations.

[0034] In some embodiments, the transducer assembly 310 may be provided with a first electrical connector (not shown), and the charging case 100 may be provided with a second electrical connector (not shown). When the first electrical connector and the second electrical connector are electrically connected, the charging case 100 and the earphone 300 can perform functions such as power transmission and data transmission. For example, when the first electrical connector and the second electrical connector are electrically connected, the charging case 100 can transmit the electrical energy in the energy storage device to the power supply device 3303 through the second electrical connector and the first electrical connector, thereby realizing the charging function of the earphone 300. It should be noted that in some embodiments, the first electrical connector may be at least one of the elements that can realize electrical connection, such as a spring pin and a spring sheet; the second electrical connector may be an element that can be electrically connected to the first electrical connector.

[0035] Since the headphone system 1000 in this embodiment includes a charging case 100, it is understood that the headphone system 1000 includes at least the same beneficial effects as the charging case 100. Therefore, for the beneficial effects of the headphone system 1000, please refer to the beneficial effects of the charging case 100 described below.

[0036] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 The charging case 100 provided in this application embodiment is used to charge earphones 300. The charging case 100 includes an earphone compartment 30, a housing 10, and a switch assembly. The earphone compartment 30 is configured to charge earphones 300 housed within it. The housing 10 has a receiving cavity 16. The switch assembly is disposed between the earphone compartment 30 and the housing 10, and the earphone compartment 30 and the housing 10 are rotatably connected. When the earphone compartment 30 is in a first position relative to the housing 10, the switch assembly is closed to connect the earphone compartment 30 and the housing 10 along a first direction X; when the earphone compartment 30 is rotated relative to the housing 10 towards the outside of the receiving cavity 16 to a second position, the switch assembly is opened, and the earphone compartment 30 and the housing 10 are separated. The first direction X is the direction from the outside to the inside of the receiving cavity 16.

[0037] Specifically, the housing 10 is a component in the charging case 100 used to house and protect the earphone compartment 30. The housing 10 is made of materials including, but not limited to, one or more combinations of plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the housing 10 is made of plastic, which makes the charging case 100 lighter, reduces its weight, and improves its portability. The space enclosed by the housing 10 is the receiving cavity 16, which houses at least a portion of the earphone compartment 30.

[0038] The earphone case 30 is a structure for accommodating and charging the earphones 300 or for transmitting data to the earphones 300. The charging cavity 331 is defined as a spatial structure for accommodating at least a portion of the earphones 300. When at least a portion of the earphones 300 is accommodated in the charging cavity 331, and the first electrical connector is electrically connected to the second electrical connector, the charging case 100 is capable of charging the earphones 300 or transmitting data with the earphones 300.

[0039] The earphone case 30 is rotatably connected to the housing 10, depending on the position of the rotation axis of the relative rotation between the earphone case 30 and the housing 10. For ease of explanation, the relative position of the earphone case 30 and the housing 10 is defined as including a first end 31 movably connected to the housing 10 and a second end 33 for taking out and placing the earphones 300. The first end 31 and the second end 33 of the earphone case are opposite each other. For example, the first end 31 of the earphone case is hinged to the housing 10, and the second end 33 of the earphone case is a free end. When the earphone case 30 rotates relative to the housing 10 through the rotatable connection between the first end 31 and the housing 10, the earphone case 30 is in a first position relative to the housing 10, that is, the second end 33 of the earphone case can approach the housing 10 and is in the first position relative to the housing 10, and the charging case 100 is in a closed state; or, the earphone case 30 rotates relative to the housing 10 towards the outside of the receiving cavity 16 to a second position, that is, the second end 33 of the earphone case can move away from the housing 10 and is in the second position relative to the housing 10, and the charging case 100 is in an open state. The charging cavity 331 is located at the second end 33 of the earphone compartment. The earphone 300 can be inserted into or removed from the charging cavity 331 to achieve removal and placement from the charging case 100. The rotation direction of the earphone compartment 30 relative to the housing 10 is referenced. Figures 1 to 2 , among which Figures 1 to 2 This refers to the direction of rotation of the earphone compartment 30 relative to the housing 10 when the charging case 100 switches from the closed state to the open state; from Figures 2 to 1 This refers to the direction of rotation of the earphone compartment 30 relative to the housing 10 when the charging case 100 switches from the open state to the closed state.

[0040] It can be understood that the second end 33 of the earphone compartment being in the first position means that the earphone compartment 30 is in the first position relative to the shell 10, and the second end 33 of the earphone compartment being in the second position means that the earphone compartment 30 is in the second position relative to the shell 10. The following question may adopt any expression method as needed.

[0041] The switch assembly is a structure used to connect or separate the earphone compartment 30 from the housing 10. The switch assembly is positioned between the earphone compartment 30 and the housing 10. When the switch assembly is closed, the earphone compartment 30 and the housing 10 are connected; when the switch assembly is open, the earphone compartment 30 and the housing 10 are separated. When the second end 33 of the earphone compartment is in the first position, the switch assembly is closed, the earphone compartment 30 and the housing 10 approach and close together, and the charging case 100 is in a closed state. At this time, the communication between the receiving cavity 16 and the outside is blocked, the charging cavity 331 is located inside the receiving cavity 16, and the earphones 300 cannot be taken out or placed in the charging case 100.

[0042] With the second end 33 of the earphone compartment in the second position, the switch assembly is opened, the earphone compartment 30 and the housing 10 are separated from each other, and the second end 33 of the earphone compartment is spaced apart from the housing 10. The charging case 100 is in the open state. At this time, the receiving cavity 16 is in communication with the outside, and at least a part of the charging cavity 331 is located outside the receiving cavity 16. At this time, the earphone 300 can be taken out and put into the charging case 100.

[0043] In the charging case 100 of this embodiment, the earphone compartment 30 is rotatably connected to the housing 10 and can move closer to or further away from the housing 10. At least a portion of the earphone 300 is housed in the charging cavity 331 so that the charging cavity 331 charges the earphone 300. The earphone compartment 30 can switch between a first position and a second position relative to the housing 10, so as to connect or separate the earphone compartment 30 from the housing 10 through a switch assembly. Specifically, when the earphone compartment 30 is in the first position relative to the housing 10, the switch assembly is closed to connect the earphone compartment 30 and the housing 10 along the first direction X, and the charging case 100 is in a closed state, and the charging case 100 can stably house the earphone 300; when the second end 53 of the earphone compartment 30 is in the second position, the switch assembly is opened, at which time the earphone compartment 30 is separated from the housing 10, the charging case 100 is in an open state, and the earphone 300 can be easily taken out and put in the charging case 100. At this time, the user can operate the charging case 100 with one hand, which is more convenient and more fun for the user to operate the charging case 100.

[0044] Please refer to Figures 1 to 3 , Figure 6 and Figure 7In some embodiments, the housing 10 includes opposing first side wall 35 11 and second side wall 37 12, a third side wall 14 connecting the first side wall 35 11 and the second side wall 37 12, and a fourth side wall 17 spaced apart from the third side wall 14. The first side wall 35 11 is closed, the second side wall 37 12 is open to form a first opening 13, and the third side wall 14 is open to form a second opening 15. The first opening 13 and the second opening 15 communicate with each other, and the receiving cavity 16 communicates with the outside through the first opening 13 and the second opening 15. The earphone compartment 30 includes opposing first side 35 and second side 37, with the second side 37 facing the receiving cavity 16. The switching assembly includes a locking member 371 and a mating member 373. One of the fourth side wall 17 and the second side 37 is provided with the locking member 371, and the other is provided with the mating member 373. When the earphone compartment 30 is in the first position relative to the housing 10, the locking member 371 and the mating member 373 are locked together to connect the earphone compartment 30 and the housing 10 along the first direction X; when the earphone compartment 30 is in the second position relative to the housing 10, the locking member 371 and the mating member 373 are released, and the earphone compartment 30 and the housing 10 are separated.

[0045] For details, please refer to Figure 6 The housing 10 includes multiple sidewalls, wherein the first sidewall 11 and the second sidewall 12 are opposite to each other, and the two ends of the third sidewall 14 are respectively connected to the first sidewall 11 and the second sidewall 12. The fourth sidewall 17 is a sidewall of the housing 10 that is spaced apart from the third sidewall 14, and the two ends of the fourth sidewall 17 are respectively connected to the first sidewall 11 and the second sidewall 12. It should be noted that the sidewalls in this application can refer to actual physical structures or virtual structures.

[0046] The first sidewall 11 is a closed structure, while the second sidewall 12 and the third sidewall 14 are open structures. The open space formed by the second sidewall 12 is the first opening 13, and the open space formed by the third sidewall 14 is the second opening 15. The first opening 13 and the second opening 15 are interconnected. The receiving cavity 16 is connected to both the first opening 13 and the second opening 15, and the receiving cavity 16 is also connected to the outside of the housing 10 through both the first opening 13 and the second opening 15.

[0047] In the thickness direction of the earphone compartment 30, the earphone compartment 30 includes a first side 35 and a second side 37, which are opposite to each other. The first side 35 faces the outside of the charging case 100, and the second side 37 faces the receiving cavity 16. The locking member 371 and the mating member 373 are configured to lock or unlock each other to fix or release the relative position of the earphone compartment 30 and the housing 10. In some embodiments, the locking member 371 is disposed on the fourth side wall 17, and the mating member 373 is disposed on the second side 37. When the second end 33 of the earphone compartment is in the first position, the locking member 371 and the mating member 373 are aligned and engage with each other. In other embodiments, the locking member 371 is disposed on the second side 37, and the mating member 373 is disposed on the fourth side wall 17. When the second end 33 of the earphone compartment is in the first position, the locking member 371 and the mating member 373 are aligned and engage with each other.

[0048] With the second end 33 of the earphone compartment in the first position, the earphone compartment 30 and the housing 10 are close together and cover each other, and the charging case 100 is in the closed state. At this time, the locking member 371 and the mating member 373 are locked together to fix the relative position of the earphone compartment 30 and the housing 10. At this time, the compression amount of the elastic member 50 is the first compression amount, and the elastic member 50 makes the earphone compartment 30 and the housing 10 tend to move away from each other.

[0049] With the second end 33 of the earphone compartment in the second position, the earphone compartment 30 and the housing 10 are far apart from each other, and the second end 33 of the earphone compartment is spaced apart from the housing 10. The charging case 100 is in the open state. At this time, the locking member 371 and the mating member 373 are unlocked, and the compression amount of the elastic member 50 is the second compression amount, which is less than the first compression amount. At this time, the elastic member 50 can be in a compressed state or a natural state.

[0050] Therefore, in the charging case 100 of this application, the locking member 371 and the mating member 373 can lock or unlock to fix or release the housing 10 and the earphone compartment 30. When the locking member 371 and the mating member 373 are unlocked, the elastic member 50 allows the earphone compartment 30 to rotate relative to the housing 10 to open the charging cavity 331, and the earphone 300 can be taken out of the charging case 100. At this time, the process of taking out the earphone 300 from the charging case 100 is simple and quick. At this time, the user can take out the earphone 300 from the charging case 100 with one hand. The user's operation of the charging case 100 is more convenient and more fun.

[0051] Please refer to Figures 1 to 3 , Figure 6 and Figure 7In some embodiments, the locking member 371 includes two locking sub-members 3711, which are spaced apart and opposite to each other. The mating member 373 includes a main body portion 3731 and two protrusions 3733, which extend from opposite sides of the main body portion 3731. When the locking member 371 and the mating member 373 are locked together, the two locking sub-members 3711 engage with the two protrusions 3733 respectively; when the locking member 371 and the mating member 373 are disengaged, the two locking sub-members 3711 disengage from the two protrusions 3733 respectively.

[0052] Specifically, the locking sub-component 3711 is the specific structure within the locking component 371 used to lock or unlock with the mating component 373. There are two locking sub-components 3711, which are opposite to each other and spaced apart. The main body 3731 is the main structure of the mating component 373, and the protrusions 3733 are structures within the mating component 373 used to mate with the locking sub-components 3711. There are two protrusions 3733, both connected to the main body 3731 and extending from opposite sides of the main body 3731. The main body 3731 and the protrusions 3733 can be integrally formed. In this case, the mating component 373 has better structural stability and greater structural strength, allowing it to mate with the locking component 371 multiple times, resulting in a longer service life. Consequently, the charging box 100 also has a longer service life. The main body 3731 and the protrusion 3733 can be molded separately, and the main body 3731 and the protrusion 3733 can be detachably connected or non-detachably connected, in which case the structure of the mating part 373 is more flexible.

[0053] Two locking sub-components 3711 correspond to two protrusions 3733 respectively. When the two locking sub-components 3711 are engaged with the two protrusions 3733 corresponding to them, the locking member 371 and the mating member 373 are locked together, and the housing 10 and the earphone compartment 30 are fixed. When the two locking sub-components 3711 are disengaged from the two protrusions 3733 corresponding to them, the locking member 371 and the mating member 373 are released from lock, and the housing 10 and the earphone compartment 30 are released from fixation. Therefore, in the charging case 100 of this application, the locking sub-components 3711 and the protrusions 3733 can engage or disengage to fix or release the housing 10 and the earphone compartment 30. When the locking part 3711 and the protrusion 3733 are disengaged, the elastic member 50 allows the earphone compartment 30 to rotate relative to the housing 10 so that the charging cavity 331 is opened, and the earphone 300 can be taken out of the charging case 100. At this time, the process of taking the earphone 300 out of the charging case 100 is simple and quick. At this time, the user can take out the earphone 300 from the charging case 100 with one hand. The user's operation of the charging case 100 is more convenient and more fun.

[0054] Please refer to Figures 1 to 3 , Figure 6 and Figure 7 In some embodiments, the housing 10 further includes a fifth sidewall 18 and a sixth sidewall 19 spaced apart from each other, both of which are connected to the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 17. First connecting members 181 are respectively provided on the fifth sidewall 18 and the sixth sidewall 19, and second connecting members 311 are respectively provided on opposite sides of the earphone compartment 30. The second connecting members 311 are rotatably engaged with the first connecting members 181, so that the earphone compartment 30 is rotatably connected to the housing 10.

[0055] Specifically, the fifth sidewall 18 and the sixth sidewall 19 are the remaining two sidewalls of the shell 10, excluding the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 17. The fifth sidewall 18 is connected to the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 17, respectively, and the sixth sidewall 19 is also connected to the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 17, respectively. The spatial structure formed by the first sidewall 11, the second sidewall 12, the third sidewall 14, the fourth sidewall 17, the fifth sidewall 18, and the sixth sidewall 19 is the receiving cavity 16. Both the fifth sidewall 18 and the sixth sidewall 19 are closed.

[0056] The first connector 181 is a structure for connecting the housing 10 to the earphone compartment 30, and is respectively disposed on the fifth side wall 18 and the sixth side wall 19. The second connector 311 is a structure for connecting the earphone compartment 30 to the housing 10, and is respectively disposed on opposite sides of the first end 31 of the earphone compartment. In some examples, the first connector 181 is a connecting hole and the second connector 311 is a rotating shaft; in other examples, the second connector 311 is a connecting hole and the first connector 181 is a rotating shaft.

[0057] The first connector 181 on the fifth sidewall 18 and the second connector 311 on one side of the first end 31 of the earphone compartment rotate with each other, and the first connector 181 on the sixth sidewall 19 and the second connector 311 on the other side of the first end 31 of the earphone compartment rotate with each other, so that the earphone compartment 30 is rotatably connected to the housing 10. Therefore, in the charging case 100 of this application, the first connector 181 on the housing 10 and the second connector 311 on the earphone compartment 30 rotate with each other, so that the earphone compartment 30 and the housing 10 can rotate relative to each other, thereby realizing the opening and closing of the charging cavity 331. The earphone 300 can be conveniently and quickly taken out and put into the charging case 100. The user can take out the earphone 300 from the charging case 100 with one hand. The user's operation of the charging case 100 is more convenient and more fun.

[0058] Please refer to Figure 6 , Figure 7 and Figure 9 In some embodiments, the housing 10 further includes a fifth sidewall 18 and a sixth sidewall 19 spaced apart from each other, both of which are connected to the first sidewall 11, the second sidewall 12, the third sidewall 14, and the fourth sidewall 17. The housing 10 also includes a first limiting member 183 disposed on the inner surface of at least one of the fifth sidewall 18 and the sixth sidewall 19. The earphone compartment 30 further includes a second limiting member 315 disposed on at least one of the opposite sides of the earphone compartment 30. The first limiting member 183 cooperates with the second limiting member 315. When the earphone compartment 30 is in a second position relative to the housing 10, the first limiting member 183 and the second limiting member 315 together limit the rotation angle of the earphone compartment 30 relative to the housing 10.

[0059] Specifically, the first limiting member 183 and the second limiting member 315 are configured to cooperate to limit the extreme angle of mutual rotation between the housing 10 and the earphone compartment 30. In some embodiments, the first limiting member 183 is disposed on the fifth side wall 18, and the second limiting member 315 is disposed on the opposite side of the earphone compartment 30 corresponding to the fifth side wall 18. In this case, the first limiting member 183 and the second limiting member 315 can cooperate well to limit the extreme angle of mutual rotation between the housing 10 and the earphone compartment 30. In other embodiments, the first limiting member 183 is disposed on the sixth side wall 19, and the second limiting member 315 is disposed on the opposite side of the earphone compartment 30 corresponding to the sixth side wall 19. In this case, the first limiting member 183 and the second limiting member 315 cooperate well to limit the extreme angle of mutual rotation between the housing 10 and the earphone compartment 30. In some other embodiments, the first limiting member 183 is respectively disposed on the fifth side wall 18 and the sixth side wall 19, and the second limiting member 315 is disposed on the opposite sides of the earphone compartment 30. The second limiting member 315 disposed on the opposite side of the earphone compartment 30, which is opposite to the fifth side wall 18, can cooperate with the first limiting member 183 disposed on the fifth side wall 18, and the second limiting member 315 disposed on the opposite side of the earphone compartment 30, which is opposite to the sixth side wall 19, can cooperate with the first limiting member 183 disposed on the sixth side wall 19. At this time, the distribution range of the first limiting member 183 and the second limiting member 315 is large, and the force is relatively uniform. The first limiting member 183 and the second limiting member 315 cooperate better to limit the extreme angle of mutual rotation between the housing 10 and the earphone compartment 30.

[0060] When the second end 33 of the earphone compartment is rotated to the second position, the first limiting member 183 and the second limiting member 315 cooperate with each other and jointly limit the rotation angle of the earphone compartment 30 away from the housing 10. That is, the cooperation of the first limiting member 183 and the second limiting member 315 makes the limit angle of rotation of the earphone compartment 30 away from the housing 10 correspond to the second position.

[0061] Therefore, in this application, the charging case 100, through the cooperation of the first limiting member 183 and the second limiting member 315, jointly limits the rotation angle of the earphone compartment 30 relative to the shell 10. At this time, the limit angle of mutual rotation between the earphone compartment 30 and the shell 10 is a fixed preset value. Therefore, the size of the open area of ​​the charging cavity 331 is a preset value. The earphone 300 is consistent in each time it is taken out and put into the charging case 100, has a foolproof function, and the user's operation of the charging case 100 is more convenient.

[0062] In some embodiments, the earphone case 30 includes a first side 35 and a second side 37 facing away from each other, with the second side 37 facing the receiving cavity 16. When the earphone case 30 is in a first position relative to the housing 10, the surface of the first side 35 is flush with the outer surface of the housing 10 closest to the earphone 300 in the positive direction X. The earphone case 30 can also be in a third position relative to the housing 10, closer to the fourth sidewall 17 of the housing 10 than in the first position. When the earphone case 30 is in the third position relative to the housing 10, the charging case 100 is in a closed state, and the surface of the first side 35 is at least partially located within the receiving cavity 16.

[0063] Specifically, in the above embodiment, in the thickness direction of the earphone compartment 30, the earphone compartment 30 includes a first side 35 and a second side 37, the first side 35 and the second side 37 are opposite to each other, wherein the first side 35 faces the outside of the charging case 100, and the second side 37 faces the receiving cavity 16.

[0064] With the second end 33 of the earphone compartment in the second position, the earphone compartment 30 and the housing 10 are far apart, and the second end 33 of the earphone compartment is spaced apart from the housing 10, and the charging case 100 is in the open state. At this time, the surface of the first side 35 is offset from the outer surface of the third side wall 14. With the second end 33 of the earphone compartment in the first position, the earphone compartment 30 and the housing 10 are close together and close to each other, and the charging case 100 is in the closed state. At this time, the surface of the first side 35 is flush with the outer surface of the third side wall 14, and the outer surface of the charging case 100 is a continuous surface without any obvious protruding structure. It can be understood that the third side wall 14 can be an actual physical structure or a virtual structure. Therefore, when the charging case 100 of this application is in the closed state, the outer surface of the charging case 100 is a continuous surface. On the one hand, the charging case 100 has a better aesthetic appearance; on the other hand, the earphone compartment 30 and the housing 10 will not be damaged by external forces due to mutual protrusion. The charging case 100 has better structural stability and a longer service life.

[0065] The fourth sidewall 17 is a sidewall in the housing 10 that is spaced apart from the third sidewall 14. Both ends of the fourth sidewall 17 are connected to the first sidewall 11 and the second sidewall 12, respectively. When the earphone compartment 30 rotates relative to the housing 10 via the rotatable connection between its first end 31 and the housing 10, the second end 33 of the earphone compartment can move further closer to the housing 10 from its first position. In its third position relative to the housing 10, it can be understood that, compared to its first position, the second end 33 of the earphone compartment is closer to the fourth sidewall 17 when it is in its third position.

[0066] Similar to the first position, when the second end 33 of the earphone compartment is in the third position, the earphone compartment 30 is close to and covers the housing 10, the charging case 100 is closed, the earphone compartment 30 simultaneously covers the first opening 13 and the second opening 15, the communication between the receiving cavity 16 and the outside is blocked, and the charging cavity 331 is located inside the receiving cavity 16. At this time, the earphone 300 cannot be taken out or put into the charging case 100. At this time, since the second end 33 of the earphone compartment is further close to the housing 10 than in the first position, the surface of the first side 35 is offset from the third side wall 14, and at least a portion of the surface of the first side 35 is located inside the receiving cavity 16.

[0067] When the second end 33 of the earphone compartment is in the first position, i.e., when the charging case 100 is closed, the housing 10 and the earphone compartment 30 are connected by a switch assembly and maintain a fixed relative position. When the user needs to open the charging case 100 to insert or remove the earphones 300, the user presses the earphone compartment 30 and / or the housing 10 in the direction opposite to the housing 10 and the earphone compartment 30, so that the second end 33 of the earphone compartment is in the third position. At this time, the switch assembly is opened, the earphone compartment 30 can be unlocked from the housing 10, and the earphone compartment 30 can rotate relative to the housing 10. When the pressure is released and the second end 33 of the earphone compartment rotates to the second position, the charging case 100 is in the open state, the charging cavity 331 is open, and the earphones 300 can be taken out of the charging case 100. It can be understood that during the process of the user opening the charging case 100, the second end 33 of the earphone compartment is pressed from the first position to the third position, then rotates from the third position to the first position and finally rotates to the second position when the pressure is released.

[0068] When the user needs to close the charging case 100, the user presses the earphone compartment 30 and / or the housing 10 in the direction opposite to the earphone compartment 30, causing the second end 33 of the earphone compartment to rotate to the first position. At this time, the earphone compartment 30 can lock with the housing 10, and the earphone compartment 30 can rotate relative to the housing 10. When the second end 33 of the earphone compartment is rotated to the first position, the charging case 100 is in the closed state, the charging cavity 331 is closed, and the earphone 300 is accommodated and sealed in the charging case 100. It can be understood that during the process of the user closing the charging case 100, the second end 33 of the earphone compartment is pressed from the second position to the first position.

[0069] Therefore, when the second end 33 of the earphone compartment is in the third position, the housing 10 and the earphone compartment 30 are unlocked, and the earphone compartment 30 can rotate relative to the housing 10 to open the charging cavity 331. The earphone 300 can be taken out of the charging case 100. At this time, the process of taking out the earphone 300 from the charging case 100 is simple and quick. At this time, the user can take out the earphone 300 from the charging case 100 with one hand. The user's operation of the charging case 100 is more convenient and more fun.

[0070] It is understandable that when the second end 33 of the earphone compartment is rotated to the third position, the first limiting member 183 and the second limiting member 315 cooperate with each other and jointly limit the rotation angle of the earphone compartment 30 when it is close to the housing 10. That is, the cooperation of the first limiting member 183 and the second limiting member 315 makes the limit angle of rotation of the earphone compartment 30 when it is close to the housing 10 correspond to the third position.

[0071] Please refer to Figure 6 , Figure 7 and Figure 9In some embodiments, the first limiting member 183 is a protrusion, and the second limiting member 315 is a fan-shaped groove. In this case, at least a portion of the protrusion is accommodated in the fan-shaped groove, and the protrusion is able to rotate in the fan-shaped groove. When the outer sidewall of the protrusion abuts against the inner sidewall of the fan-shaped groove, the relative rotation between the housing 10 and the earphone compartment 30 is restricted.

[0072] In other embodiments, the second limiting member 315 is a protrusion, and the first limiting member 183 is a fan-shaped groove. In this case, at least a portion of the protrusion is accommodated in the fan-shaped groove, and the protrusion is rotatable in the fan-shaped groove. When the outer wall of the protrusion abuts against the inner wall of the fan-shaped groove, the relative rotation between the housing 10 and the earphone compartment 30 is restricted.

[0073] Please refer to Figure 6 , Figure 7 and Figure 9 In some embodiments, the end face of the protrusion is arc-separated from the fan-shaped groove. The fan-shaped groove includes a first limiting surface 3111 and a second limiting surface 3113, which are respectively connected to the arc surface of the fan-shaped groove. The protrusion includes a third limiting surface 1831 and a fourth limiting surface 1833. The third limiting surface 1831 and the fourth limiting surface 1833 are located on opposite sides of the protrusion, with the third limiting surface 1831 facing the first limiting surface 3111 and the fourth limiting surface 1833 facing the second limiting surface 3113. When the earphone compartment 30 is in the first position relative to the housing 10, the third limiting surface 1831 and the first limiting surface 3111 are spaced apart, and the fourth limiting surface 1833 and the second limiting surface 3113 are spaced apart; when the earphone compartment 30 is in the second position relative to the housing 10, the third limiting surface 1831 and the first limiting surface 3111 are spaced apart, and the fourth limiting surface 1833 and the second limiting surface 3113 are in contact; when the earphone compartment 30 is in the third position relative to the housing 10, the third limiting surface 1831 and the first limiting surface 3111 are in contact, and the fourth limiting surface 1833 and the second limiting surface 3113 are spaced apart.

[0074] Specifically, when the housing 10 and the earphone compartment 30 rotate relative to each other, the part where the first connector 181 and the second connector 311 engage is the central axis of rotation. As the housing 10 and the earphone compartment 30 rotate relative to each other, the protrusion rotates around the central axis within the fan-shaped groove. With the end face of the protrusion furthest from the central axis and the arc-shaped groove furthest from the central axis, the protrusion does not rub against the inner wall of the fan-shaped groove during its rotation around the central axis, thus ensuring a smoother relative rotation process between the housing 10 and the earphone compartment 30.

[0075] The first limiting surface 1831 is a plane of the fan-shaped groove used to limit the extreme position of the earphone compartment 30's rotation towards the housing 10. The second limiting surface 1833 is a plane of the fan-shaped groove used to limit the extreme position of the earphone compartment 30's rotation away from the housing 10. The first limiting surface 1831 and the second limiting surface 1833 are respectively connected to both sides of the arc surface of the fan-shaped groove. The third limiting surface 1835 is a plane of the protrusion used to limit the extreme position of the earphone compartment 30's rotation towards the housing 10. The fourth limiting surface 1837 is a plane of the protrusion used to limit the extreme position of the earphone compartment 30's rotation away from the housing 10. In the rotation direction of the protrusion, the third limiting surface 1835 and the fourth limiting surface 1837 are respectively located on opposite sides of the protrusion.

[0076] The third limiting surface 1835 and the first limiting surface 1831 are opposite to each other and can cooperate to jointly limit the extreme position of the earphone compartment 30 to rotate close to the housing 10, that is, the case where the second end 33 of the earphone compartment is in the third position; the fourth limiting surface 1837 and the second limiting surface 1833 are opposite to each other and can cooperate to jointly limit the extreme position of the earphone compartment 30 to rotate away from the housing 10, that is, the case where the second end 33 of the earphone compartment is in the second position.

[0077] When the second end 33 of the earphone compartment is in the first position, the earphone compartment 30 is located between the extreme position of rotation of the earphone compartment 30 close to the housing 10 and the extreme position of rotation of the earphone compartment 30 away from the housing 10. At this time, the third limiting surface 1835 and the first limiting surface 1831 are spaced apart, and the fourth limiting surface 1837 and the second limiting surface 1833 are spaced apart. When the second end 33 of the earphone compartment is in the second position, the earphone compartment 30 is located at the extreme position of rotation of the earphone compartment 30 away from the housing 10. The third limiting surface 1835 and the first limiting surface 1831 are spaced apart, and the fourth limiting surface 1837 and the second limiting surface 1833 are in contact. When the second end 33 of the earphone compartment is in the third position, the earphone compartment 30 is located at the extreme position of rotation of the earphone compartment 30 close to the housing 10. The third limiting surface 1835 and the first limiting surface 1831 are in contact, and the fourth limiting surface 1837 and the second limiting surface 1833 are spaced apart.

[0078] Therefore, in the charging case 100 of this application, the protrusion and the fan-shaped groove can cooperate with each other to limit the extreme position of the earphone compartment 30 relative to the shell 10. At this time, the extreme angle of the earphone compartment 30 and the shell 10 relative to each other is a fixed preset value. Therefore, the size of the open area of ​​the charging cavity 331 is a preset value. The earphone 300 is consistent in each time it is taken out and put in the charging case 100, which has a foolproof function. The way the user operates the charging case 100 is more convenient.

[0079] Please refer to Figure 1 and Figure 2In some embodiments, when the earphone compartment 30 is in the second position relative to the housing 10, the included angle θ between the earphone compartment 30 and the housing 10 is greater than or equal to 20 degrees and less than or equal to 30 degrees.

[0080] Specifically, the second position is the extreme position where the earphone compartment 30 is furthest away from the housing 10. When the earphone compartment 30 is in the second position relative to the housing 10, the angle θ between the earphone compartment 30 and the housing 10 is: the angle θ between the surface of the earphone compartment 30 closest to the housing 10 in the second direction and the surface of the housing 10 closest to the earphone compartment 30 in the second direction, such as... Figure 2 As shown. The angle θ between the earphone compartment 30 and the housing 10 determines the maximum extent to which the earphone compartment 30 and the housing 10 can be separated, and directly affects the ease with which the user can take the earphones 300 out of the charging case 100 when the second end 53 of the earphone compartment 30 is in the second position, that is, when the charging case 100 is in the open state.

[0081] In the above embodiments, the angle θ between the earphone compartment 30 and the housing 10 can be, but is not limited to, any one or any two of 20 degrees, 21 degrees, 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees, 28 degrees, and 30 degrees. If the angle θ between the earphone compartment 30 and the housing 10 is less than 20 degrees, the separation between the earphone compartment 30 and the housing 10 is too small when the charging case 100 is in the open state, making it difficult for the user to take the earphones 300 out of the charging case 100, and the earphones 300 are prone to contact or bumping against the charging case 100 and being damaged. If the angle θ between the earphone compartment 30 and the housing 10 is greater than 30 degrees, the separation between the earphone compartment 30 and the housing 10 is too large when the charging case 100 is in the open state, the overall size of the charging case 100 in the open state is large, making it difficult for the user to operate the charging case 100 with one hand, reducing the portability of the charging case 100, and resulting in a poor user experience. Therefore, the angle θ between the earphone compartment 30 and the shell 10 is within the range mentioned above. This ensures that the process of the user taking the earphones 300 out of the charging case 100 is simple and smooth, and also ensures that the overall size of the charging case 100 is small when it is open, so that the user can operate the charging case 100 with one hand, thus improving the user experience of the charging case 100.

[0082] Please refer to Figures 1 to 3 and Figure 7 In some embodiments, the charging case 100 further includes an elastic member 50. The elastic member 50 is disposed between the earphone compartment 30 and the housing 10, and is connected to both the housing 10 and the earphone compartment 30. The elastic member 50 is configured to provide an elastic restoring force for the earphone compartment 30 relative to the housing 10 to switch from a first position to a second position.

[0083] Specifically, the elastic element 50 is a device that provides elastic restoring force for the second end 33 of the earphone compartment to switch from the first position to the second position. The elastic element 50 can be, but is not limited to, a combination of one or more springs, leaf springs, and rubber elastic elements. When the elastic element 50 is a spring, it has the advantages of simple structure and low cost. When the elastic element 50 is a leaf spring, it has the advantage of high load-bearing capacity. When the elastic element 50 is a rubber elastic element, it has the advantages of wear resistance and corrosion resistance. At least a portion of the elastic element 50 is connected to the housing 10, and at least a portion of the elastic element 50 is connected to the earphone compartment 30.

[0084] The connection between the elastic element 50 and the housing 10 can be an abutment connection or a fixed connection. When the connection between the elastic element 50 and the housing 10 is a fixed connection, the connection method can be either a detachable connection or a non-detachable connection. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering methods. This definition will be used for detachable and non-detachable connections in the following context and will not be elaborated further. The connection between the elastic element 50 and the earphone compartment 30 can be an abutment connection or a fixed connection. When the connection between the elastic element 50 and the earphone compartment 30 is a fixed connection, the connection method can be either a detachable connection or a non-detachable connection.

[0085] When the housing 10 and the earphone compartment 30 are unlocked, the elastic element 50 provides an elastic restoring force to the earphone compartment 30 and / or the housing 10, allowing the earphone compartment 30 and the housing 10 to move relative to each other. The second end 33 of the earphone compartment switches from the third position to the first position and then to the second position. Therefore, in the charging case 100 of this application, the elastic element 50 provides an elastic restoring force for the process of the second end 33 of the earphone compartment switching from the third position to the first position and then to the second position. The rotation of the earphone compartment 30 relative to the housing 10 is relatively easy, and the opening and closing of the charging cavity 331 is relatively easy to achieve. The earphones 300 can be conveniently and quickly taken out of the charging case 100. Users can take out the earphones 300 from the charging case 100 with one hand. The user's operation of the charging case 100 is more convenient and more fun.

[0086] Please refer to Figures 1 to 3 and Figure 7 In some embodiments, the earphone compartment 30 is further provided with a mounting member 313, and the elastic member 50 is sleeved on the mounting member 313. The mounting member 313 and the second connecting member 311 are an integral structure or a separate structure.

[0087] Specifically, the mounting member 313 is a structure used to stably install the elastic member 50 between the earphone compartment 30 and the housing 10. The mounting member 313 is located at the first end 31 of the earphone compartment, and at least a portion of the elastic member 50 can be fitted onto the mounting member 313 so that the elastic member 50 is installed at the first end 31 of the earphone compartment. When the second connecting member 311 is a solid structure such as a rotating shaft, the mounting member 313 can be an integral structure with the second connecting member 311. In this case, the structural strength of the mounting member 313 and the second connecting member 311 is greater, the installation of the elastic member 50 at the first end 31 of the earphone compartment is more stable, and the structural strength of the mating structure of the first connecting member 181 and the second connecting member 311 is greater, and the rotation of the housing 10 and the earphone compartment 30 is more stable. The mounting member 313 can also be a separate structure from the second connecting member 311, in which case the structure of the mounting member 313 and the second connecting member 311 is more flexible.

[0088] In some examples, the elastic element 50 includes a first end 51 and a second end 53. The first end 51 of the elastic element is connected to the earphone compartment 30, and the second end 53 of the elastic element is connected to the housing 10. When the elastic element 50 is decompressed, the first end 51 of the elastic element transmits an elastic restoring force to the earphone compartment 30 through its connection with the earphone compartment 30, and the second end 53 of the elastic element transmits an elastic restoring force to the housing 10 through its connection with the housing 10. The earphone compartment 30 and the housing 10 experience elastic restoring forces in opposite directions. Therefore, the earphone compartment 30 and the housing 10 move away from each other, allowing the charging cavity 331 to open. The earphones 300 can then be easily and quickly placed into the charging case 100. Users can remove the earphones 300 from the charging case 100 with one hand, making the user's operation of the charging case 100 more convenient and enjoyable.

[0089] In other examples, the elastic element 50 includes a first end 51, a second end 53, and a third end 55, with the third end 55 located between the first end 51 and the second end 53 of the elastic element. The first end 51 and the second end 53 of the elastic element are connected to one of the earphone compartment 30 and the housing 10, and the third end 55 of the elastic element is connected to the other of the earphone compartment 30 and the housing 10.

[0090] Please refer to Figures 1 to 3 and Figure 7This application describes an example where the first end 51 and the second end 53 of the elastic element are connected to the housing 10, and the third end 55 of the elastic element is connected to the earphone compartment 30. In this case, when the elastic element 50 is decompressed, the first end 51 and the second end 53 of the elastic element transmit elastic restoring force to the housing 10 through their connection with the housing 10, and the third end 55 of the elastic element transmits elastic restoring force to the earphone compartment 30 through its connection with the earphone compartment 30. The direction of the elastic restoring force on the earphone compartment 30 and the housing 10 is opposite. Therefore, the earphone compartment 30 and the housing 10 are separated from each other, so that the charging cavity 331 is open. The earphone 300 can be conveniently and quickly taken out and placed in the charging case 100. The user can take out the earphone 300 from the charging case 100 with one hand. The user's operation of the charging case 100 is more convenient and more fun.

[0091] Please refer to Figures 1 to 3 In some embodiments, the earphone case 30 includes a first side 35 and a second side 37 facing away from each other, with the second side 37 facing the receiving cavity 16. The first side 35 has a cutout area 351 that connects the interior of the charging case 100 with the exterior of the charging case 100. When the earphone 300 is housed in the earphone case 300, at least a portion of the earphone 300 is housed in the cutout area 351 and communicates with the exterior of the charging case 100.

[0092] Specifically, the cutout area 351 is used to connect the interior of the charging case 100, i.e., the charging cavity 331, to the exterior of the charging case 100. The cutout area 351 is located on the first side 35. When the earphone 300 is not placed in the charging cavity 331, the charging cavity 331 is an empty cavity. At this time, the user can clearly and directly observe whether the earphone 300 is placed in the charging cavity 331 through the cutout area 351, making it easier for the user to quickly determine the next operation on the charging case 100 and the earphone 300. When the earphone 300 is placed in the charging cavity 331, at least a portion of the earphone 300 is placed in the charging cavity 331, and at least a portion of the earphone 300 is placed in the cutout area 351, communicating with the exterior of the charging case 100. At this time, the user can clearly and directly observe whether the earphone 300 is placed in the charging cavity 331 through the cutout area 351, and the process of removing the earphone 300 through the cutout area 351 is also easier.

[0093] Therefore, in the charging case 100 of this application, the first side 35 of the charging compartment is provided with a hollow area 351 that connects the charging cavity 331 and the outside of the charging case 100. When the earphone 300 is housed in the charging cavity 331 and at least partially housed in the hollow area 351, the user can operate the earphone 300 through the hollow area 351 to conveniently and quickly remove the earphone 300, making the operation of the charging case 100 more convenient and faster. Furthermore, the user can clearly and directly observe whether the earphone 300 is housed in the charging cavity 331 through the hollow area 351, allowing the user to quickly determine the next step in operating the charging case 100 and the earphone 300, resulting in a better user experience.

[0094] Please refer to Figure 6 , Figure 8 and Figure 9 In some embodiments, the housing 10 includes a first sidewall 11, the inner surface of which is provided with a clearance groove 111.

[0095] Specifically, the clearance groove 111 is a structure used to prevent the earphone case 30 and / or the earphone 300 housed in the charging cavity 331 from colliding with the first sidewall 11 during rotation relative to the housing 10. The clearance groove 111 is located on the inner surface of the first sidewall 11, and the size and shape of the clearance groove 111 are respectively matched with the overall size and shape of the earphone case 30 and the earphone 300 housed in the charging cavity 331. When the earphone compartment 30 rotates relative to the housing 10 to switch the second end 33 of the earphone compartment between the first position, the second position and the third position, the space provided by the clearance groove 111 prevents the earphone compartment 30 and / or the earphone 300 housed in the charging cavity 331 from colliding with the first side wall 11. At this time, the surface of the earphone compartment 30 and / or the earphone 300 will not be scratched by the housing 10, the appearance of the earphone compartment 30 and / or the earphone 300 will not be damaged, and the earphone compartment 30 and / or the earphone 300 will not be subjected to external impact. The structure of the earphone system 1000 is relatively stable and the service life of the earphone system 1000 is relatively long.

[0096] Please refer to Figures 6 to 8 In some embodiments, the earphone compartment 30 is provided with a first chamfer 317 at one end near the housing 10. As the earphone compartment 30 moves away from the housing 10, the first chamfer 317 is configured to avoid the housing 10.

[0097] Specifically, in the above embodiment, the first chamfer 317 is a structure used to prevent the earphone compartment 30 from colliding with the housing 10 during the process of rotating relative to the housing 10 and moving away from the housing 10. The first chamfer 317 is located at the end of the first end 31 of the earphone compartment near the housing 10. When the earphone compartment 30 rotates relative to the housing 10 and moves away from the housing 10, such as when the second end 33 of the earphone compartment switches from the first position to the second position, the presence of the first chamfer 317 reduces the space occupied by the earphone compartment 30, preventing the earphone compartment 30 from colliding with the fourth side wall 17. At this time, the surface of the earphone compartment 30 will not be scratched by the housing 10, the appearance of the earphone compartment 30 will not be damaged, and the earphone compartment 30 will not be subjected to external impact. The earphone compartment 30 has good structural stability, and the charging case 100 has a long service life.

[0098] Please refer to Figures 6 to 8 In some embodiments, the earphone compartment 30 is provided with a second chamfer 319 at one end near the housing 10. As the earphone compartment 30 approaches the housing 10, the second chamfer 319 is configured to avoid the housing 10.

[0099] Specifically, in the above embodiment, the second chamfer 319 is a structure used to prevent the earphone compartment 30 from colliding with the housing 10 during the process of the earphone compartment 30 rotating relative to the housing 10 to approach the housing 10. The second chamfer 319 is located at the end of the first end 31 of the earphone compartment that is close to the housing 10. At this time, the second chamfer 319 is further away from the first connector 181 than the first chamfer 317. When the earphone compartment 30 rotates relative to the housing 10 and moves away from the housing 10, such as when the second end 33 of the earphone compartment switches from the first position to the third position, the presence of the second chamfer 319 reduces the space occupied by the earphone compartment 30, and the earphone compartment 30 will not collide with the fourth side wall 17. At this time, the surface of the earphone compartment 30 will not be scratched by the housing 10, the appearance of the earphone compartment 30 will not be damaged, and the earphone compartment 30 will not be subjected to external impact. The earphone compartment 30 has good structural stability, and the charging case 100 has a long service life.
