It should be noted that, for the convenience of understanding, in the accompanying drawings of the specification of the utility model embodiment, the downward direction is indicated as the first direction, and the upward direction is indicated as the second direction, wherein the first direction is parallel to the second direction.

[0044] The utility model embodiment provides a kind of charging bin for containing earphone unit and ear cap, refer to Figure 1 And Figure 2As shown, the charging bin 100 comprises a bin body 110, a fixing member 120, a connecting part 130 and a cover body 150. The bin body 110 has an internal cavity structure defining an accommodating space 111. The accommodating space 111 is used to accommodate components of the charging bin 100, such as a battery, a circuit board and the fixing member 120. The fixing member 120 is connected to the bin body 110 and arranged in the accommodating space 111. The fixing member 120 comprises a first mounting part 121 and a second mounting part 122 connected to each other. The first mounting part 121 is used to mount the earphone unit 200, and the second mounting part 122 is used to mount the ear cap 300. The connecting part 130 is connected to the second mounting part 122 and used to connect and fix the ear cap 300 when the ear cap 300 is mounted on the second mounting part 122. The cover body 150 is used to prevent the earphone unit 200 and the ear cap 300 from falling out of the bin body 110. The cover body 150 is connected to the bin body 110 and covers the first mounting part 121 and the second mounting part 122. The cover body 150 can be moved relative to the bin body 110 to open or close the first mounting part 121 and the second mounting part 122.

[0045] In the prior art, after the ear cap 300 is detached from the earphone unit 200, the user needs to store the ear cap 300 (e.g., in a pocket or a bag). However, the ear cap 300 is small and light in weight, and thus it is difficult to be immediately noticed when it is lost, resulting in low safety of the ear cap 300. In the technical scheme of the present application, the fixing member 120 is provided with the first mounting part 121 and the second mounting part 122 to accommodate the earphone unit 200 and the ear cap 300. When the ear cap 300 is not used, the ear cap 300 can be accommodated in the second mounting part 122 to avoid loss of the ear cap 300. Meanwhile, the connecting part 130 is arranged in the second mounting part 122 to connect and fix the ear cap 300, thereby improving the connection stability of the ear cap 300 and the storage safety of the ear cap 300. After the ear cap 300 is stored, the cover body 150 is used to close the first mounting part 121 and the second mounting part 122, so that the ear cap 300 cannot be separated from the bin body 110, further improving the safety of the ear cap 300.

[0046] In this embodiment, referring to Figure 5 As shown, the ear cap 300 has a hollow structure 321, and the connecting part 130 is a structure extending in the second direction (upward). The connecting part 130 is arranged in the hollow structure 321 of the ear cap 300 to limit and fix the ear cap 300.

[0047] In another embodiment, referring to Figure 6As shown, the connecting portion 130 is a groove structure recessed in the first direction (downward), and the connecting portion 130 has a groove wall. When the ear cap 300 is connected to the connecting portion 130, at least a portion of the ear cap 300 is accommodated in the connecting portion 130. The ear cap 300 accommodated in the connecting portion 130 is pressed by the groove wall of the connecting portion 130, and is thus fixed in the connecting portion 130. In some embodiments, referring to Figure 9 As shown, the ear cap 300 includes an ear sleeve 310 and a fixing portion 320. In the vertical direction, if the fixing portion 320 extends downward by a length greater than the length of the ear sleeve 310, the connecting relationship between the fixing portion 320 and the connecting portion 130 is that the fixing portion 320 is accommodated in the connecting portion 130 and abuts against the groove wall of the connecting portion 130. If the fixing portion 320 extends downward by a length smaller than the length of the ear sleeve 310, the connecting relationship between the fixing portion 320 and the connecting portion 130 is that the ear sleeve 310 and the fixing portion 320 are jointly accommodated in the connecting portion 130, and the groove wall of the connecting portion 130 is wrapped on the outside of the ear sleeve 310, thereby limiting and fixing the ear cap 300.

[0048] In some embodiments, referring to Figure 5As shown, in the first direction, the cover 150 is spaced apart from the upper surface of the fixing member 120. Since the upper surface of the second mounting portion 122 is communicated by the accommodating cavity 123 to form an opening 1231, it can also be understood that the cover 150 and the opening 1231 are spaced apart. The side of the cover 150 facing the second mounting portion 122 has a spacing H from the upper surface of the second mounting portion 122. Specifically, when the ear cap 300 is accommodated in the second mounting portion 122, if the ear cap 300 is not installed to the designated position, the spacing H can avoid the cover 150 from rubbing against the ear cap 300 when opening and closing the second mounting portion 122, thereby avoiding the abrasion of the ear cap 300. In other embodiments, the cover 150 and the upper surface of the second mounting portion 122 can also not have the spacing H. By increasing the recess degree of the sunken groove structure 1221, the depth of the sunken groove structure 1221 in the first direction is greater than the height of the ear cap 300, thereby also avoiding the abrasion of the ear cap 300 when opening and closing. In some embodiments, the cover 150 is rotationally connected to the cartridge body 110, and the cover 150 and the cartridge body 110 have a rotational axis 151, and the cover 150 can rotate relative to the cartridge body 110 around the rotational axis 151, thereby realizing the sequential opening or closing of the first mounting portion 121 and the second mounting portion 122, i.e., the opening or closing of the first mounting portion 121 and the second mounting portion 122 in a sequence. It should be noted that the opening in the sequence here does not mean that the first mounting portion 121 needs to be opened or closed first, and then the second mounting portion 122 needs to be opened or closed. Instead, the opening and closing of the first mounting portion 121 and the second mounting portion 122 have a sequence, such as: first opening the first mounting portion 121, and then opening the second mounting portion 122; or first opening the second mounting portion 122, and then opening the first mounting portion 121. The same is true for closing. Specifically, in some embodiments, referring to Figure 10 As shown, when the cover 150 is in the closed state, the cover 150 covers the first mounting portion 121 and the second mounting portion 122. When the cover 150 is in the open state, the cover 150 opens the first mounting portion 121 and the second mounting portion 122. When the cover 150 starts to rotate from the closed state, the first mounting portion 121 and the second mounting portion 122 will be opened in sequence under the rotation of the cover 150, so as to sequentially take or place the earphone unit 200 or the ear cap 300, thereby avoiding the cover 150 from exposing the first mounting portion 121 and the second mounting portion 122 at one time, and reducing the risk of the ear cap 300 falling when taking or placing the earphone unit 200, or the risk of the earphone unit 200 falling when taking or placing the ear cap 300.

[0049] Further, in some embodiments, the rotation axis 151 of the cover 150 and the cartridge 110 is disposed between the first mounting portion 121 and the second mounting portion 122. That is, the center of the first mounting portion 121 and the center of the second mounting portion 122 are respectively located on the two sides of the rotation axis 151. It should be noted that the rotation axis 151, the center of the first mounting portion 121 and the center of the second mounting portion 122 do not necessarily need to be located on the same straight line. For the convenience of understanding and description, refer to Figure 10 In this embodiment, the first mounting portion 121 is disposed on the left side of the rotation axis 151, and the second mounting portion 122 is disposed on the right side of the rotation axis 151. In the left-right direction, the rotation axis 151 is between the center of the first mounting portion 121 and the center of the second mounting portion 122. Figure 10 In this embodiment, the rotation axis 151, the center of the first mounting portion 121 and the center of the second mounting portion 122 are not located on the same straight line. When the cover 150 rotates relative to the cartridge 110 in the clockwise direction to open the second mounting portion 122 to take out or store the ear cap 300, the cover 150 can rotate in the opposite direction, that is, in the counterclockwise direction, to close the second mounting portion 122 and open the first mounting portion 121, thereby taking out or storing the earphone unit 200. Finally, the cover 150 is rotated to the closed state. In this way, the rotation path of the earphone unit 200 and the ear cap 300 can be made the shortest, and the convenience of using the earphone 10 can be improved.

[0050] In this embodiment, refer to Figure 1 and Figure 2 The first mounting portion 121 and the second mounting portion 122 are separately disposed, and the outer wall of the first mounting portion 121 and the outer wall of the second mounting portion 122 are connected. In this way, the space occupied by the first mounting portion 121 and the second mounting portion 122 is reduced, the overall volume of the cartridge 110 is reduced, and the earphone unit 200 and the ear cap 300 can be stored separately to avoid mutual interference during installation. In another embodiment, the first mounting portion 121 and the second mounting portion 122 can also be continuously disposed. That is, the first mounting portion 121 and the second mounting portion 122 do not have a separating groove wall. In the case of a reasonable distance between the first mounting portion 121 and the second mounting portion 122, the earphone unit 200 and the ear cap 300 can also avoid mutual interference during installation.

[0051] In some embodiments, refer to Figure 3 and Figure 4As shown, the second mounting portion 122 has a sink structure 1221 formed by the second mounting portion 122 recessed in the first direction. The sink structure 1221 includes an inner circumferential wall 1222 and a bottom wall surface 1223, the inner circumferential wall 1222 is connected to the bottom wall surface 1223, and the inner circumferential wall 1222 is circumferentially disposed on the bottom wall surface 1223. The inner circumferential wall 1222 and the bottom wall surface 1223 together define a receiving cavity 123 for accommodating the ear cap 300. The connecting portion 130 is connected to the bottom wall surface 1223 and disposed in the receiving cavity 123. Further, the second mounting portion 122 also includes an opening 1231 formed by the receiving cavity 123 leading through the second mounting portion 122 in the second direction, the opening 1231 is adapted to access the ear cap 300. When the cover 150 is provided on the first mounting portion 121 and the second mounting portion 122, the cover 150 will be disposed at the opening 1231 to close the receiving cavity 123, so as to prevent the ear cap 300 from falling out of the receiving cavity 123. Specifically, in this embodiment, referring to Figure 4 As shown, in the vertical direction, the sink structure 1221 is disposed at the upper portion of the cartridge body 110, and the sink structure 1221 is formed by the second mounting portion 122 recessed downward, i.e., recessed towards the inside of the receiving space 111, thereby forming a groove for accommodating the ear cap 300. The recessed formation of the sink structure 1221 enables the charging cartridge 100 to have a position for accommodating the ear cap 300 without increasing the size of the charging cartridge 100.

[0052] Meanwhile, the sink structure 1221 can also be formed at other positions of the cartridge body 110. In another embodiment, in the vertical direction, the sink structure 1221 is disposed at the lower portion of the cartridge body 110, and the sink structure 1221 is formed by the second mounting portion 122 protruding upward, i.e., protruding towards the inside of the receiving space 111. In other embodiments, the sink structure 1221 can also be formed by the second mounting portion 122 recessed in the left-right direction, and the sink structure 1221 is disposed on the lateral wall of the cartridge body 110, i.e., on the side wall of the cartridge body 110. Thus, when the ear cap 300 is not in use, the charging cartridge 100 can also have the function of accommodating the ear cap 300 without increasing the size of the charging cartridge 100.

[0053] In some embodiments, referring to Figure 4 to Figure 9 As shown, the second mounting portion 122 includes a support portion 124 disposed in the receiving cavity 123. The support portion 124 is connected to the bottom wall surface 1223 on one side, and the support portion 124 has an abutting surface 1241 on the side away from the bottom wall surface 1223. The connecting portion 130 is connected to the abutting surface 1241, and the circumferential dimension of the connecting portion 130 is smaller than the circumferential dimension of the abutting surface 1241, and the abutting surface 1241 is adapted to abut the ear cap 300. Specifically, referring to Figure 5As shown, the surface area of the abutting surface 1241 is larger than the cross-sectional area of the connecting portion 130 in the horizontal direction (i.e. transverse direction). After the connecting portion 130 is connected to the abutting surface 1241, the abutting surface 1241 still has a part of the area that is empty, which is used to abut the ear cap 300. When the ear cap 300 is connected to the connecting portion 130, the ear cap 300 needs to be installed to a specified position before the cover 150 can be normally covered on the first mounting portion 121 and the second mounting portion 122. If the ear cap 300 is not installed to the specified position, when the cover 150 is covered on the second mounting portion 122, the ear cap 300 will rub against the cover 150, causing the ear cap 300 to be worn, or the ear cap 300 will hinder the movement of the cover 150, so that the cover 150 cannot be covered on the second mounting portion 122 to close the accommodation cavity 123. The abutting surface 1241 can be used to determine whether the ear cap 300 is installed to the specified position, and the abutting surface 1241 will indicate whether the ear cap 300 is installed to the specified position. In this embodiment, the ear cap 300 is connected to the connecting portion 130 in the vertical direction, and when the bottom of the ear cap 300 abuts against the abutting surface 1241, the abutting surface 1241 will limit the ear cap 300 from moving downward in the vertical direction, which means that the ear cap 300 has been installed to the specified position. At this position, the cover 150 is covered on the second mounting portion 122, and the ear cap 300 will not hinder the cover 150. At the same time, the abutting surface 1241 can be provided to reduce the contact between the ear cap 300 and the bottom wall surface 1223 after the ear cap 300 is installed on the second mounting portion 122, so as to avoid friction between the ear cap 300 and the bottom wall surface 1223 when the cartridge body 110 shakes, causing the ear cap 300 to be worn.

[0054] In other embodiments, a pressure sensor is provided on the abutting surface 1241, and an indicator light is provided on the cartridge body 110. When the ear cap 300 is installed, if the ear cap 300 abuts against the abutting surface 1241, the pressure sensor will sense the pressure applied by the ear cap 300 to the abutting surface 1241, and through the cooperation of the pressure sensor and the indicator light, the user can know whether the ear cap 300 has been installed to the specified position and whether the cover 150 can be normally closed.

[0055] In some embodiments, referring to Figure 4As shown, in the vertical direction, one end of the support portion 124 is connected to the bottom wall surface 1223, and the other end is connected to the connecting portion 130. Among them, the connection between the support portion 124 and the bottom wall surface 1223 is a circular arc transition, and at the same time, the connection between the abutting surface 1241 and the connecting portion 130 is a circular arc transition. Specifically, the support portion 124 and the bottom wall surface 1223, the abutting surface 1241 and the connecting portion 130 are connected through the circular arc structure 140. Compared with other transition modes, such as: right angle transition, using the circular arc structure 140 can reduce the sharp part of the connection, avoid the sharp part of the connection after the ear cap 300 is connected to the connecting portion 130. Contact with the ear cap 300 to cause scratches and other damage to the ear cap 300. At the same time, the use of the circular arc structure 140 can reduce the stress concentration of each component at the connection, thereby improving the strength and service life of the second mounting portion 122. And, the use of the circular arc structure 140 can also improve the appearance quality of the second mounting portion 122, avoid burrs, defects and other adverse conditions at the connection.

[0056] The earphone 10 of the second aspect of the present application will be described below with reference to the drawings of the specification. Referring to Figure 7 and Figure 8 As shown, the earphone 10 includes the charging bin 100, the earphone unit 200 and the ear cap 300 described in any of the above embodiments. Among them, the earphone unit 200 is detachably connected to the first mounting portion 121. The ear cap 300 is detachably connected to the earphone unit 200, so that the earphone 10 has a first state and a second state. Among them, the first state of the earphone 10 is an in-ear state, and the second state is a semi-in-ear state. By adjusting the connection relationship between the ear cap 300 and the earphone unit 200, the use state of the earphone 10 can be changed.

[0057] Referring to Figure 7 As shown, when the earphone 10 is in the first state, the ear cap 300 is connected to the earphone unit 200, and after the earphone 10 is used, the earphone unit 200 and the ear cap 300 are jointly installed on the first mounting portion 121.

[0058] Referring to Figure 8 As shown, when the earphone 10 is in the second state, the ear cap 300 is separated from the earphone unit 200, and the ear cap 300 and the earphone unit 200 are separately arranged, and the ear cap 300 is installed on the second mounting portion 122.

[0059] The earphone 10 can be switched between the half-ear-in state and the ear-in state through the disassembly and assembly of the earphone unit 200 and the ear cap 300. In the first state, the ear cap 300 is connected to the earphone unit 200, and the earphone 10 is in the ear-in state. After the earphone 10 is used, the earphone unit 200 and the ear cap 300 can be collectively accommodated in the first mounting portion 121, and it is not necessary to disassemble again to improve the use convenience of the earphone 10. In the second state, the ear cap 300 is separated from the earphone unit 200, and the user uses the earphone unit 200 alone. At this time, the earphone 10 is in the half-ear-in state, and the ear cap 300 can be accommodated in the second mounting portion 122 to avoid the loss of the ear cap 300.

[0060] In some embodiments, the earphone 10 comprises two pairs of ear caps 300, wherein the specifications of the two pairs of ear caps 300 can be the same. Alternatively, the specifications of the two pairs of ear caps 300 are different to adapt to users with different ear shapes. In use, the used ear cap 300 can be assembled on the earphone unit 200, and the other pair of ear cap 300 not in use can be accommodated in the second mounting portion 122.

[0061] In some embodiments, referring to FIG. 2, Figure 9 As shown in FIG. 2, the ear cap 300 comprises an ear sleeve 310 and a fixing portion 320, and the ear cap 300 is connected to the fixing portion 320. Specifically, the inside of the fixing portion 320 is a hollow structure 321, and in this embodiment, the hollow structure 321 leads through the fixing portion 320 away from the end of the ear sleeve 310 in the first direction (downward). That is, the fixing portion 320 has oppositely arranged first and second ends, wherein the first end is connected to the ear cap 300, the hollow structure 321 of the fixing portion 320 leads through the second end, and the second end is formed with an inlet and outlet. When the ear cap 300 is connected and fixed to the connecting portion 130, the connecting portion 130 is arranged in the hollow structure 321 through the inlet and outlet to limit the circumferential movement of the ear cap 300.

[0062] Further, after the connecting portion 130 is inserted into the hollow structure 321, the connecting portion 130 also needs to limit the ear cap 300 in the axial direction (vertical direction) to prevent the ear cap 300 from moving relative to the connecting portion 130 in the axial direction. Specifically, in this embodiment, the fixing portion 320 includes a flexible soft rubber portion, i.e., at least a portion of the fixing portion 320 is made of a flexible soft rubber material. The flexible soft rubber portion is interference-fitted to the connecting portion 130. The volume of the hollow structure 321 of the fixing portion 320 is smaller than the volume of the connecting portion 130, so that after the connecting portion 130 is inserted into the hollow structure 321 of the fixing portion 320, the outer peripheral wall of the connecting portion 130 tightly abuts against the inner wall of the hollow structure 321. At this time, the flexible soft rubber portion is interference-fitted to the connecting portion 130, thereby increasing the friction between the connecting portion 130 and the fixing portion 320, and the friction prevents the fixing portion 320 from moving relative to the connecting portion 130 in the axial direction. Further, the elastic modulus of the flexible soft rubber portion is smaller than the elastic modulus of the connecting portion 130. The flexible soft rubber portion is made of a flexible rubber material, which includes but is not limited to rubber, silicone, etc. Since the flexible rubber material has good elasticity and wear resistance, when the ear cap 300 contacts the human body, the flexible rubber material can tightly abut against the ear canal, thereby improving the sound insulation effect, and the service life of the flexible rubber material is long and is not easy to wear. At the same time, the flexible rubber material has a relatively large friction coefficient, and when the fixing portion 320 is connected and fixed to the connecting portion 130, the flexible rubber material can increase the friction between the fixing portion 320 and the connecting portion 130, thereby also achieving the effect of preventing the fixing portion 320 from moving relative to the connecting portion 130 in the axial direction.

[0063] In another embodiment, the connecting portion 130 includes a flexible soft rubber portion, i.e., at least a portion of the connecting portion 130 is made of a flexible soft rubber material, and the flexible soft rubber portion is interference-fitted to the fixing portion 320. Specifically, when the fixing portion 320 is connected and fixed to the connecting portion 130, the flexible soft rubber portion is inserted into the hollow structure 321 of the fixing portion 320. The volume of the hollow structure 321 is smaller than the volume of the flexible soft rubber portion, so that the flexible soft rubber portion tightly abuts against the inner wall of the hollow structure 321 of the fixing portion 320, thereby increasing the friction between the connecting portion 130 and the fixing portion 320, and the friction prevents the fixing portion 320 from moving relative to the connecting portion 130 in the axial direction. In other embodiments, the connecting portion 130 is clearance-fitted to the fixing portion 320. At this time, the volume of the hollow structure 321 is greater than or equal to the volume of the connecting portion 130. After the connecting portion 130 is inserted into the hollow structure 321, the connecting portion 130 still contacts the inner wall of the fixing portion 320, and the connecting portion 130 and the fixing portion 320 still have friction, thereby also achieving the effect of preventing the fixing portion 320 from moving relative to the connecting portion 130 in the axial direction.

[0064] In some embodiments, with reference to Figure 9As shown, the ear cap 300 further comprises a connecting member 330, which is connected to the inner wall of the hollow structure 321 and covers the outer wall surface of the second end of the fixing portion 320. The fixing portion 320 has a first end and a second end arranged oppositely, the first end is connected to the ear cap 300, and the fixing member 120 covers the outer wall surface of the second end of the fixing portion 320. When the earphone 10 is in the first state, the ear cap 300 is connected to the earphone unit 200, at this time, the ear cap 300 is connected and fixed to the earphone unit 200 through the connecting member 330; when the earphone 10 is in the second state, the ear cap 300 is separated from the earphone unit 200, at this time, the ear cap 300 is connected and fixed to the connecting portion 130 through the connecting member 330.

[0065] Specifically, in one of the examples, referring to Figure 9 As shown, the connecting member 330 is fixedly attached to the inner wall of the hollow structure 321, and at the same time, the connecting member 330 covers the second end and is bent to form a buckle structure at the second end. When the earphone 10 is in the first state, the connecting member 330 is buckled on the earphone unit 200 through the buckle structure to realize the connection of the ear cap 300 and the earphone unit 200. When the ear cap 300 is detached from the earphone unit 200, because the ear cap 300 is made of flexible material, extruding the fixing portion 320 makes the connecting member 330 move towards the axis of the hollow structure 321, so that the connecting member 330 is separated from the earphone unit 200. When the earphone 10 is in the second state, the ear cap 300 is connected and fixed to the connecting portion 130, at this time, the inner wall of the connecting member 330 is attached to the outer wall of the connecting portion 130. Because of the existence of the connecting member 330, the volume of the hollow structure 321 is smaller than the volume of the connecting portion 130 at this time, so that the fixing portion 320 and the connecting portion 130 are connected in interference, thereby the ear cap 300 is fixed to the connecting portion 130 through the connecting member 330.

[0066] In another embodiment, the connecting member 330 is provided with external threads, which are located on the outer wall surface of the second end when the connecting member 330 covers the second end. Similarly, internal threads are provided at the position where the earphone unit 200 connects the ear cap 300, thereby the connecting member 330 fixes the ear cap 300 to the earphone unit 200 through threaded connection. In other embodiments, the connecting member 330 can also be a rubber ring, which is arranged around the inner wall of the hollow structure 321 and covers the outer wall surface of the second end of the fixing portion 320. Because the rubber ring has a large friction coefficient, by increasing the friction between the connecting member 330 and the earphone unit 200, or between the connecting member 330 and the connecting portion 130, the ear cap 300 is assembled on the earphone unit 200 or the connecting portion 130.

[0067] In some embodiments, referring to Figure 7 and Figure 8As shown, the first mounting portion 121 comprises a receiving groove 1211 and a fixing groove 1212, and the receiving groove 1211 is in communication with the fixing groove 1212. The earphone unit 200 comprises an ear handle 210. In the first state, the ear cap 300 is connected to the earphone unit 200, and the ear cap 300 and the earphone unit 200 are jointly accommodated in the receiving groove 1211, and the ear handle 210 is arranged in the fixing groove 1212. In this embodiment, when the earphone unit 200 and the ear cap 300 are accommodated in the receiving groove 1211, the ear cap 300 abuts against the bottom of the receiving groove 1211. At this time, the ear cap 300 is subjected to the pressure applied by the earphone unit 200, and the ear cap 300 is clamped between the bottom of the receiving groove 1211 and the earphone unit 200. In the vertical direction, the fixing height of the ear handle 210 is higher than the fixing height of the ear cap 300. Therefore, when the ear handle 210 is arranged in the fixing groove 1212, the ear handle 210 can provide a pulling force for the ear cap 300 in the vertical direction, reduce the pressure suffered by the ear cap 300, and avoid damage to the ear cap 300 due to the pressure after the ear cap 300 is accommodated in the receiving groove 1211.

[0068] In some embodiments, referring to Figure 3 、 Figure 7 and Figure 8 , the earphone 10 further comprises a sensing portion 400 arranged in the receiving space 111, the fixing groove 1212 is provided with a through hole 1213 in the first direction, the through hole 1213 is in communication with the receiving space 111, and the sensing portion 400 is arranged in the through hole 1213 and connected to the ear handle 210. Specifically, in this embodiment, the inside of the storage body 110 defines the receiving space 111, and the fixing member 120 divides the receiving space 111 into two regions in the vertical direction, one of which is used to accommodate electronic components such as circuit boards and batteries, and the other of which is used to accommodate the earphone unit 200, the ear cap 300 and the cover body 150. The fixing groove 1212 is provided with a through hole 1213 in the vertical direction, and the through hole 1213 communicates the two regions of the receiving space 111. The sensing portion 400 is arranged in the region of the receiving space 111 for accommodating electronic components, and the sensing portion 400 extends in the second direction (upward) and passes through the through hole 1213. The side of the ear handle 210 facing the sensing portion 400 is provided with a corresponding connecting hole, and the ear handle 210 is fixed to the sensing portion 400 through the connecting hole.

[0069] When the ear stem 210 is connected to the induction portion 400, the induction portion 400 limits the circumferential movement of the ear stem 210 to fix the earphone unit 200 in the accommodating groove 1211, and the cover 150 is covered on the first mounting portion 121 to limit the axial movement of the earphone unit 200, so that the earphone unit 200 is connected and fixed in the first mounting portion 121. Moreover, the earphone 10 can not only position the earphone unit 200 through the induction portion 400 to stably place the earphone unit 200 in the accommodating groove 1211, but also can sense the position of the earphone unit 200 through the induction portion 400. When the induction portion 400 detects that the earphone unit 200 is located in the accommodating groove 1211, the induction portion 400 will turn on the power supply to the earphone unit 200 to charge the earphone unit 200.

[0070] The embodiments of the utility model are explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
