DETAILED DESCRIPTION

[0031] The embodiments of the present application will be further described below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0032] In the description of the embodiments of the present application, it should be noted that the terms "center", "left", "right", "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the embodiments of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third" and the like are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0033] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "communication" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0034] In the earphone, the sound unit and the battery pack usually form a clamping on the auricle together, and the sound unit is usually worn at the middle position of the concha cavity.

[0035] In the related art, in a moving state, the battery pack located behind the ear is usually prone to downward movement due to its own gravity, and the downward movement of the battery pack is prone to causing a certain offset of the sound production unit, resulting in that the sound hole of the sound production unit cannot be effectively aligned with the ear canal, and the sound transmission effect of the ear-clamping earphone is reduced.

[0036] Based on the above situation, an embodiment of the present application provides a wearing-stable ear-clamping earphone 10, please refer to Figures 1 to 7 . The ear-clamping earphone 10 comprises a sound production unit 11, a battery pack 12 and a connecting assembly 13. The sound production unit 11 is used to be placed in the concha cavity. The battery pack 12 is used to be placed behind the ear. The battery pack 12 is electrically connected with the sound production unit 11. The connecting assembly 13 connects the battery pack 12 and the sound production unit 11, so that the sound production unit 11 and the battery pack 12 jointly form a clamping to the pinna. Wherein, one end of the sound production unit 11 has a seat sleeve 111. The seat sleeve 111 has an accommodation space 111a. Part of the connecting assembly 13 is accommodated in the accommodation space 111a. The surfaces of the connecting assembly 13 and the accommodation space 111a used for contact are formed as spherical surfaces, so that the connecting assembly 13 can be universally swung relative to the sound production unit 11.

[0037] It should be noted that the ear-clamping earphone 10 is an open earphone. The sound production unit 11 of the open earphone does not need to be inserted into the ear canal, but is outside the ear canal. The sound hole of the sound production unit 11 faces the ear canal to directly transmit sound into the ear canal. At the same time, the open earphone is fixed on the pinna by a clip or a clamping ring.

[0038] Wherein, the pinna is a part of the external ear, which is a device for collecting sound waves.

[0039] The concha cavity, also known as the ear nest or ear shell depression, is a part of the external ear, specifically a recessed area near the center of the ear where the pinna (the cartilaginous structure part of the external ear) is located. It is located between the foot of the helix and the antihelix, and is a relatively open space. The concha cavity is a prominent anatomical landmark of the pinna and plays a certain acoustic role in the structure of the ear, which can help capture and guide sound into the ear canal.

[0040] The sound production unit 11 is one of the core components of the ear-clamping earphone 10, which is used to convert electrical signals into sound. The sound production unit 11 can include a loudspeaker or a driver, which can include a magnet, a voice coil and a diaphragm. When an electric current passes through the voice coil, a changing magnetic field is generated, which interacts with the magnet, causing the diaphragm to vibrate and thus producing sound waves.

[0041] The specific structure of the sound production unit 11 is not limited, which can be moving coil type, electrostatic type or flat plate magnetic type, etc., which is not limited here.

[0042] The shape of the sound production unit 11 is not limited, which can be approximately circular, oval or square, etc., which is not limited here.

[0043] The sound generating unit 11 is arranged in the concha cavity, which can reduce the pressure caused by inserting the sound generating unit 11 into the ear canal, and reduce the discomfort caused by long-term wearing. At the same time, the concha cavity is relatively close to the ear canal opening, which facilitates the transmission of audio signals from the sound generating unit 11 to the eardrum.

[0044] The battery pack 12 is used to provide power support for the sound generating unit 11, so that the clip-on earphone 10 can work without being directly connected to an external power source. Exemplarily, the battery pack 12 can include one or more rechargeable batteries.

[0045] The battery pack 12 is placed behind the ear, which can help balance the weight of the ear clip earphone, reduce the pressure on the ear, and not occupy the space of the ear canal, so that the wearing is more comfortable.

[0046] The connecting assembly 13 connects the battery pack 12 and the sound generating unit 11. The sound generating unit 11 is located in front of the ear and arranged in the concha cavity, and the battery pack 12 is located behind the ear, so that the sound generating unit 11 and the battery pack 12 form a clamping on the pinna from the front and back of the ear respectively, thereby realizing the wearing of the clip-on earphone 10.

[0047] The connecting assembly 13 and the battery pack 12 are not limited in the connection mode, which can be adhesive, clamping, etc., which is not limited here.

[0048] The surfaces of the connecting assembly 13 and the accommodating space 111a for contact are formed as spherical surfaces, which means that the connecting assembly 13 and the seat sleeve 111 form spherical surface contact and cooperation. Therefore, the connecting assembly 13 and the seat sleeve 111 form a spherical pair, and the relative movement between the connecting assembly 13 and the seat sleeve 111 is spherical movement, so that the connecting assembly 13 can perform universal swing relative to the sound generating unit 11. In this way, the user can apply external force to the connecting assembly 13, so that the connecting assembly 13 can perform universal movement relative to the sound generating unit, adjust the position of the connecting assembly 13 and the battery pack 12 to adapt to different wearing needs, increase the wearing stability, and at the same time, the sound generating unit 11 can remain substantially stationary during the movement of the connecting assembly 13, so that the sound hole of the sound generating unit 11 remains facing the ear canal, without subsequent adjustment of the position of the sound generating unit 11.

[0049] The connecting assembly 13 and the seat sleeve 111 form a spherical pair, so that the connecting assembly 13 can be universally swung relative to the sound generating unit 11. For different ear shapes, only the sound hole of the sound generating unit 11 needs to be directed to the ear canal when worn, and the adaptive wearing of the clip-on earphone 10 can be realized by changing the position of the battery pack 12 behind the ear through the movement of the connecting assembly 13, thereby improving the convenience and comfort of wearing. When the battery pack 12 moves behind the ear, the sound generating unit 11 can remain substantially stationary during the movement of the connecting assembly 13 driven by the battery pack 12, which can reduce the influence of the movement of the battery pack 12 on the position and angle of the sound hole of the sound generating unit 11, so that the sound hole of the sound generating unit 11 remains directed to the ear canal, thereby improving the stability of wearing during use and further improving the stability of sound transmission. In addition, the universal swinging mode can also increase the smoothness of movement and reduce the movement restriction of the connecting assembly 13.

[0050] The specific structure of the connecting assembly 13 is not limited.

[0051] In some embodiments, referring to Figures 1 to 7 The connecting assembly 13 includes a connecting arm 131 and a connecting piece 132 connected to each other. Part of the connecting piece 132 is provided in a spherical surface and accommodated in the accommodating space 111a. One end of the connecting arm 131 away from the connecting piece 132 is connected to the battery pack 12. The sound generating unit 11 includes a shell portion 112. The outer surface of the shell portion 112 is recessed in a first direction away from the connecting arm 131 to form a recess 112a. The seat sleeve 111 is detachably arranged in the recess 112a. The first direction is parallel to the axial direction of the connecting piece 132.

[0052] Part of the connecting piece 132 is provided in a spherical surface and accommodated in the accommodating space 111a, which means that one end of the connecting piece 132 forming a spherical surface is connected to the seat sleeve 111, thereby realizing the connection with the sound generating unit 11, and the other end of the connecting piece 132 away from the spherical surface is connected to the connecting arm 131, thereby realizing the connection between the connecting assembly 13 and the sound generating unit 11.

[0053] It can be understood that the connecting arm 131 and the connecting piece 132 can be a split structure or an integral structure. For example, the connecting arm 131 and the connecting piece 132 are manufactured separately.

[0054] It should be noted that the recess 112a is used to install the seat sleeve 111. The seat sleeve 111 is detachably arranged in the recess 112a, so that the installation between the seat sleeve 111 and the shell portion 112 is simpler.

[0055] The groove 112a can provide the mounting space 131b for the seat sleeve 111, and limit the seat sleeve 111, so that the relative position of the seat sleeve 111 is fixed, the connecting piece 132 is stably matched with the seat sleeve 111, and the universal swing relative to the sound unit 11 is realized. At the same time, the setting of the groove 112a can also reduce the protruding part of the shell part 112, hide the butt joint of the seat sleeve 111 and the connecting piece 132, reduce the external protruding part, and increase the appearance reliability of the earphone 10.

[0056] In this embodiment, the first direction is parallel to the axial direction of the connecting piece 132, that is, the recess direction of the groove 112a is the same as the axial direction of the connecting piece 132, so as to facilitate the connection of the groove 112a and the seat sleeve 111, and also facilitate the butt joint installation of the seat sleeve 111 and the end of the connecting piece 132 which is provided with the spherical surface.

[0057] The specific structure of the seat sleeve 111 is not limited.

[0058] Exemplarily, in some embodiments, the seat sleeve 111 can be an integral structure.

[0059] In other embodiments, please refer to Figure 4 and Figure 5 The seat sleeve 111 includes a first half shell 1111 and a second half shell 1112 designed in a split manner. The first half shell 1111 and the second half shell 1112 are butted along a second direction and define an accommodation space 111a. The second direction is perpendicular to the first direction.

[0060] The seat sleeve 111 includes a first half shell 1111 and a second half shell 1112 designed in a split manner, that is, the seat sleeve 111 is split into two sub-pieces, which can reduce the difficulty of installation. Exemplarily, the first half shell 1111 can be butted with the connecting piece 132 first, and then the second half shell 1112 is butted with the connecting piece 132, which facilitates the adaptation between the seat sleeve 111 and the connecting piece 132. When it is necessary to disengage the butt joint of the connecting piece 132 and the seat sleeve 111, the connecting relationship between the first half shell 1111 and the second half shell 1112 can be disengaged first, and then the connecting piece 132 is disengaged, which makes the disassembly of the connecting piece 132 more convenient.

[0061] Exemplarily, the first half shell 1111 and the second half shell 1112 are symmetrical pieces, and the first half shell 1111 and the second half shell 1112 can be symmetrically arranged about the second direction. The first half shell 1111 and the second half shell 1112 can be respectively attached to the half spherical surface part of the connecting piece 132. In this way, the first half shell 1111 and the second half shell 1112 can be shared, which can increase the part sharing and interchangeability, and reduce the production cost.

[0062] The second direction can be any direction perpendicular to the first direction, that is, perpendicular to the axial direction of the connecting piece 132, which is not limited here.

[0063] Exemplarily, the second direction is parallel to the extending direction of the through hole 112b. Figures 3 to 5 For example, the second direction is parallel to the extending direction of the through hole 112b.

[0064] In some embodiments, referring to Figure 4 The shell part 112 is provided with a through hole 112b. The through hole 112b is in communication with the groove 112a. The connecting column 14 is arranged in the through hole 112b, the first half shell 1111 and the second half shell 1112 along the second direction to connect the shell part 112, the first half shell 1111 and the second half shell 1112.

[0065] It should be noted that the through hole 112b provided on the shell part 112 can penetrate one end side wall or both end side walls of the shell part 112 along the second direction, so that the connecting column 14 can extend into the through hole 112b through the penetrated side wall, which is beneficial for installation.

[0066] The through hole 112b is in communication with the groove 112a, so that when the connecting column 14 is arranged in the through hole 112b, a part of the connecting column 14 is located in the through hole 112b to realize the connection between the connecting column 14 and the shell part 112, and another part is located in the groove 112a to realize the connection between the connecting column 14 and the first half shell 1111 or the second half shell 1112.

[0067] Exemplarily, the number of connecting columns 14 is two, and the number of through holes 112b is also two. One connecting column 14 is arranged in the through hole 112b and the first half shell 1111, and the other connecting column 14 is arranged in the other through hole 112b and the second half shell 1112.

[0068] In this embodiment, by arranging the through hole 112b in communication with the groove 112a on the shell part 112, and arranging the connecting column 14 in the through hole 112b, the first half shell 1111 and the second half shell 1112 along the second direction, the detachable connection between the seat cover 111 and the shell part 112 is simpler and more reliable.

[0069] It can be understood that in this embodiment, the first half shell 1111 and the second half shell 1112 are connected by the connecting column 14, which can fix the relative position of the seat cover 111 in the groove 112a, and the relative movement between the first half shell 1111, the second half shell 1112 and the shell part 112 will not occur, which increases the reliability of the universal swing of the connecting piece 132, and also reduces the probability of the seat cover 111 shaking in the groove 112a or even falling out of the groove 112a when the connecting piece 132 moves.

[0070] In some embodiments, referring to Figure 1 , Figure 3 and Figure 6The connecting piece 132 comprises a ball head 1321 and a column 1322 which are connected to each other. At least part of the ball head 1321 is accommodated in the accommodating space 111a. The column 1322 is arranged outside the accommodating space 111a. An end of the column 1322 away from the ball head 1321 is arranged in and connected to the connecting arm 131.

[0071] The ball head 1321 refers to a structure with a spherical appearance. The ball head 1321 and the column 1322 can be an integral structure or a split structure, which is not limited herein.

[0072] At least part of the ball head 1321 is accommodated in the accommodating space 111a. The ball head 1321 can be partially accommodated in the accommodating space 111a, or the ball head 1321 can be entirely accommodated in the accommodating space 111a.

[0073] In the embodiment in which part of the ball head 1321 is accommodated in the accommodating space 111a, another part of the ball head 1321 can be located outside the accommodating space 111a. The part can be located in the groove 112a or outside the shell portion 112, which is not limited in particular.

[0074] The end of the column 1322 away from the ball head 1321 is arranged in and connected to the connecting arm 131. That is, the end of the column 1322 away from the ball head 1321 extends into the connecting arm 131. Part of the column 1322 is located outside the connecting arm 131 and outside the accommodating space 111a, so that the connecting arm 131 and the seat sleeve 111 have a certain interval. The interval provides a space for the ball head 1321 to swing relative to the shell portion 112. The connecting assembly 13 has a larger rotation space to drive the battery pack 12 to adjust the position relative to the sound generating unit 11.

[0075] In some embodiments, referring to Figures 1 to 3 Part of the ball head 1321 protrudes from the accommodating space 111a toward one side of the column 1322. The surface of the seat sleeve 111 along the first direction toward the column 1322 is a first end surface 111b. The outer surface of the column 1322 is formed as a limiting surface 1322a. The limiting surface 1322a and the first end surface 111b are separably matched to limit the rotation of the connecting piece 132 relative to the seat sleeve 111 about the first axis. The first axis is parallel to the radial direction of the column 1322 and passes through the center of the ball head 1321.

[0076] Part of the ball head 1321 protrudes from the accommodating space 111a toward one side of the column 1322. That is, part of the ball head 1321 is accommodated in the accommodating space 111a. Part of the ball head 1321 protrudes from the accommodating space 111a toward one side of the column 1322, thereby providing a certain space for the ball head 1321 to swing.

[0077] The detachable cooperation between the limiting surface 1322a and the first end surface 111b means that the limiting surface 1322a and the first end surface 111b can be limited by contact cooperation, and can also be separated. In the separated state, the limiting surface 1322a does not limit the radial swing of the ball head 1321.

[0078] As shown in Figure 5 , the first axis is represented by b.

[0079] The first axis is perpendicular to Figure 3 the cross section shown, and passes through the ball center of the ball head 1321.

[0080] It should be noted that, in Figure 3 , the angle β is the angle through which the connecting member 132 can rotate clockwise about the first axis relative to the seat sleeve 111, and the angle γ is the angle through which the connecting member 132 can rotate counterclockwise about the first axis relative to the seat sleeve 111. By cooperation of the first end surface 111b and the limiting surface 1322a on the left and right sides in Figure 3 , the rotation angle of the connecting member 132 about the first axis relative to the seat sleeve 111 is limited.

[0081] Exemplarily, the part of the column 1322 protrudes from the connecting arm 131, so that the shell part 112 and the connecting arm 131 are spaced apart by a certain distance, which can reduce the probability of friction and wear between the shell part 112 and the connecting arm 131 of the sound generating unit 11, and improve the situation that the outer surface of the connecting arm 131 and the outer surface of the shell part 112 are easily scratched.

[0082] In this embodiment, when the seat sleeve 111 rotates relative to the connecting member 132 about the radial direction of the connecting member 132, for example, rotates in the second direction, the limiting surface 1322a can limit the first end surface 111b, thereby limiting the rotation of the connecting member 132 about the first axis. In this way, the sound generating unit 11 can be omni-directionally swung within a certain angle range relative to the connection assembly 13.

[0083] Exemplarily, the total angle range through which the connecting member 132 rotates about the first axis relative to the seat sleeve 111 is 20° to 40°, and the total angle range is the sum of the angle β and the angle γ. For example, 20°, 22°, 25°, 27°, 30°, 31°, 34°, 36°, 38°, 40°, etc.

[0084] Exemplarily, the total angle range through which the connecting member 132 rotates about the first axis relative to the seat sleeve 111 is 30°, and the sum of the angle β and the angle γ is 30°.

[0085] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7The connecting assembly 13 further comprises a fixing pin 133. The connecting arm 131 has a connecting hole 131a penetrating in the third direction and a mounting space 131b for accommodating at least part of the column 1322. The connecting hole 131a is in communication with the mounting space 131b. The fixing pin 133 is arranged in the connecting hole 131a to connect the connecting arm 131 and the column 1322. The third direction intersects the first direction.

[0086] It should be noted that the third direction can be parallel, perpendicular or intersected with the second direction as the connecting assembly 13 rotates and swings relative to the sound unit 11.

[0087] Exemplarily, the third direction is perpendicular to the first direction.

[0088] Exemplarily, the connecting arm 131 is further provided with an opening in communication with the mounting space 131b, and an end of the column 1322 away from the ball head 1321 extends into the mounting space 131b through the opening.

[0089] The connecting hole 131a is in communication with the mounting space 131b, so that when the fixing pin 133 is arranged in the connecting hole 131a, a part of the fixing pin 133 is matched with the connecting hole 131a, and another part is matched with the column 1322 in the mounting space 131b, thereby realizing the connection between the connecting arm 131 and the column 1322.

[0090] The connecting hole 131a penetrates the connecting arm 131 in the third direction, thereby facilitating the fixing pin 133 to extend into the connecting hole 131a from one side of the connecting hole 131a and be connected with the connecting arm 131 and the column 1322 respectively, which can simplify the connection structure between the connecting arm 131 and the connecting member 132 and reduce the assembly difficulty of the connecting assembly 13.

[0091] In some embodiments, referring to Figure 3 and Figure 6 , an end of the connecting member 132 away from the connecting arm 131 protrudes in the first direction away from an end of the seat sleeve 111 to form a protruding structure 1323. The shell part 112 forms a limiting protrusion 112c. The limiting protrusion 112c protrudes from a side of the recess 112a facing the seat sleeve 111. The limiting protrusion 112c is located on a rotation path of the connecting member 132 in the axial direction. The limiting protrusion 112c is separably matched with the protruding structure 1323 to limit the rotation of the connecting member 132 relative to the seat sleeve 111 around the second axis, which is parallel to the axial direction of the column 1322 and passes through the center of the ball head 1321.

[0092] The limiting protrusion 112c protrudes from the side of the recess 112a facing the seat sleeve 111, that is, the limiting protrusion 112c extends in the first direction to form.

[0093] The number of the limiting protrusions 112c can be one, two, three, four, or five, etc. The number of the protruding structures 1323 can also be one, two, three, four, or five, etc. The number of the limiting protrusions 112c can be the same as or different from the number of the protruding structures 1323.

[0094] Exemplarily, the number of the limiting protrusions 112c and the protruding structures 1323 is at least two, and the protruding structure 1323 extends into the space between two adjacent limiting protrusions 112c. When the seat cover 111 rotates relative to the connecting member 132 around the second axis of the connecting member 132, the side wall of the protruding structure 1323 contacts the side wall of the limiting protrusion 112c, thereby limiting the rotation angle of the seat cover 111 around the second axis.

[0095] The limiting protrusion 112c and the protruding structure 1323 are separably matched. The limiting protrusion 112c and the protruding structure 1323 can be matched by interference in the rotation direction, i.e., contact to limit, or can be matched by separation to form a certain interval, thereby enabling relative movement.

[0096] As shown in Figure 3 and Figure 6 , the second axis is denoted by c.

[0097] In this embodiment, the rotation angle of the connecting member 132 relative to the seat cover 111 around the second axis is limited by the limiting protrusion 112c and the protruding structure 1323, which can improve the situation that the connecting member 132 rotates too much around the sound generating unit 11, causing the connecting line passing through the connecting member 132 to be easily damaged due to excessive torsion.

[0098] Exemplarily, the rotation angle of the connecting member 132 relative to the seat cover 111 around the second axis ranges from 40° to 60°. For example, 40°, 42°, 45°, 47°, 50°, 51°, 54°, 56°, 58°, 60°, etc.

[0099] Exemplarily, the rotation angle of the connecting member 132 relative to the seat cover 111 around the second axis ranges from 50°.

[0100] In some embodiments, referring to Figure 6 , the number of the protruding structures 1323 is two. The two protruding structures 1323 are symmetrically arranged about the axis of the connecting member 132.

[0101] In some embodiments, referring to Figure 4 and Figure 5 , the number of the limiting protrusions 112c is two. The two limiting protrusions 112c are symmetrically arranged about the axis of the connecting member 132.

[0102] In some embodiments, the number of protruding structures 1323 is two. The two protruding structures 1323 are symmetrically arranged about the axis of the connecting piece 132, and the number of limiting protrusions 112c is two, which are symmetrically arranged about the axis of the connecting piece 132. In this way, when one of the limiting protrusions 112c is in contact with the protruding structure 1323, the other limiting protrusion 112c is also in contact with the protruding structure 1323 at the same time, thereby increasing the contact area of the limiting and improving the reliability of the limiting.

[0103] In some embodiments, referring to Figures 1 to 3 , and Figure 7 , the connecting arm 131 comprises a first subsegment 1311 and a second subsegment 1312 connected to each other. The end of the first subsegment 1311 away from the second subsegment 1312 is connected to the connecting piece 132. The end of the second subsegment 1312 away from the first subsegment 1311 is connected to the battery pack 12. At least one protruding buckle 1312a is formed on the inner side wall of the second subsegment 1312. The end of the first subsegment 1311 close to the second subsegment 1312 forms a first contraction segment 1311a. At least one clamping groove 1311b is formed on the first contraction segment 1311a. The first contraction segment 1311a is arranged in the second subsegment 1312, and the buckle 1312a is clamped into the clamping groove 1311b.

[0104] Exemplarily, the end of the first subsegment 1311 away from the second subsegment 1312 forms a mounting space 131b and a connecting hole 131a.

[0105] At least one protruding buckle 1312a is formed on the inner side wall of the second subsegment 1312, which means that the second subsegment 1312 forms an inner hole, and the buckle 1312a is formed on the inner side wall of the inner hole.

[0106] It can be understood that the number of buckles 1312a can be one, two, three, four, or five, etc., which is not limited here.

[0107] The first contraction segment 1311a on the first subsegment 1311 can extend into the inner hole of the second subsegment 1312, and the clamping groove 1311b formed on the first contraction segment 1311a is clamped and matched with the buckle 1312a on the inner side wall, thereby realizing the connection of the first subsegment 1311 and the second subsegment 1312.

[0108] It can be understood that the number of clamping grooves 1311b can correspond to the number of buckles 1312a. The number of clamping grooves 1311b can be one, two, three, four, or five, etc., which is not limited here.

[0109] Exemplarily, the number of the clamping grooves 1311b and the clamping buckles 1312a is multiple, and the multiple clamping grooves 1311b and the multiple clamping buckles 1312a are clamped and matched, so as to improve the connection strength between the first sub-section 1311 and the second sub-section 1312.

[0110] In this embodiment, the connecting arm 131 is divided into the first sub-section 1311 and the second sub-section 1312, and the first sub-section 1311 and the second sub-section 1312 are connected through the clamping buckles 1312a and the clamping grooves 1311b. The first sub-section 1311 is connected with the connecting piece 132, and the first sub-section 1311 can be a soft structure. The second sub-section 1312 is connected with the battery pack 12, and the second sub-section 1312 can be a hard structure. Thus, the two ends of the connecting arm 131 are connected with the connecting piece 132 and the battery pack 12 respectively, so as to increase the structural strength of the connecting arm 131 as a whole. In addition, the first sub-section 1311 and the second sub-section 1312 have high docking stability, so as to reduce the probability of movement out.

[0111] In some embodiments, referring to Figure 1 , Figure 3 and Figure 6 , the earphone 10 includes a connecting line. The connecting assembly 13 is provided with a wire passing channel 132a. The wire passing channel 132a penetrates through the connecting arm 131 and the connecting piece 132. One end of the connecting line is electrically connected with the battery pack 12, and the other end passes through the wire passing channel 132a to be electrically connected with the sound generating unit 11.

[0112] Part of the wire passing channel 132a is arranged on the connecting piece 132, so that the connecting line can pass into the connecting piece 132 from one end and pass out from the other end.

[0113] One end of the connecting line passes through the connecting arm 131 to be electrically connected with the battery pack 12, and the other end passes through the wire passing channel 132a to be electrically connected with the sound generating unit 11. The connecting assembly 13 is used to connect the connecting arm 131 and the seat cover 111, and is also provided with the wire passing channel 132a, so that the wire of the connecting line is simpler, and the connection structure between the sound generating unit 11 and the connecting assembly 13 is simplified. In addition, the connecting line is hidden in the connecting assembly 13 through the wire passing channel 132a, so as to reduce the probability of winding of the user wearing the earphone 10, improve the user experience, and protect the connecting line, reduce the probability of damage of the connecting line, and improve the appearance of the earphone 10.
