[0035] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0036] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0037] Combination Figure 1 The user's ear 100 may include an external auditory canal 101, a cavum conchae 102, a cymba conchae 103, a triangular fossa 104, an antihelix 105, a scaphoid 106, an auricle 107, and an antitragus 108. Although the external auditory canal 101 has a certain depth and extends to the eardrum, for the sake of convenience of description, and in combination with Figure 1 In the present application, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity 102, the hymena conchae 103, the triangular fossa 104 and other physiological parts have a certain volume and depth; and the concha cavity 102 is directly connected to the external auditory canal 101, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity 102.

[0038] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ears. For the convenience of description, and to reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR. Therefore, in this application, descriptions such as "the user wears the earphones", "the earphones are in a wearing state" and "in a wearing state" may refer to the earphones described in this application being worn on the ears of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences between the earphones worn by different users and the earphones worn on the ears of the aforementioned simulator, but such differences should be tolerated.

[0039] It should be noted that in the fields of medicine and anatomy, three basic planes of the human body can be defined: the sagittal plane, the coronal plane, and the horizontal plane, as well as three basic axes: the sagittal axis, the coronal axis, and the vertical axis. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis refers to an axis along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis refers to an axis along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis refers to an axis along the up-down direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear" mentioned in this application is a concept relative to the "back side of the ear". The former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head. They are both for the user's ear. Among them, by observing the ear of the above simulator along the direction of the human coronal axis, it can be obtained that Figure 1 Schematic diagram of the front profile of the ear shown.

[0040] As an example, in combination Figures 2 to 5 The earphone 10 may include a movement module 11 and a hook structure 12 connected to the movement module 11, the movement module 11 is located on the front side of the ear in the worn state, and at least part of the hook structure 12 is located on the back side of the ear in the worn state, so that the earphone 10 is hung on the ear in the worn state. The movement module 11 may have a connecting end CE connected to the hook structure 12 and a free end FE not connected to the hook structure 12. Further, the movement module 11 may be configured not to block the external auditory canal in the worn state, so that the earphone 10 acts as an "open earphone". Due to individual differences among different users, when the earphone 10 is worn by different users, the movement module 11 may partially block the external auditory canal, but the external auditory canal is still not blocked.

[0041] In order to improve the stability of the earphone 10 when being worn, the earphone 10 may adopt any one of the following methods or a combination thereof. First, at least a portion of the hook-shaped structure 12 is configured as a contoured structure that fits at least one of the back side of the ear and the head, so as to increase the contact area between the hook-shaped structure 12 and the ear and / or the head, thereby increasing the resistance of the earphone 10 to falling off from the ear. Second, at least a portion of the hook-shaped structure 12 is configured as an elastic structure so that it has a certain amount of deformation when being worn, so as to increase the positive pressure of the hook-shaped structure 12 on the ear and / or the head, thereby increasing the resistance of the earphone 10 to falling off from the ear. Third, at least a portion of the hook-shaped structure 12 is configured to abut against the head when being worn, so as to form a reaction force that presses the ear, so that the movement module 11 is pressed against the front side of the ear, thereby increasing the resistance of the earphone 10 to falling off from the ear. Fourthly, the movement module 11 and the hook structure 12 are configured to clamp the physiological parts such as the area where the antihelix is ​​located and the area where the cavum concha is located from the front and back sides of the ear when worn, thereby increasing the resistance of the earphone 10 to fall off the ear. Fifthly, the movement module 11 or the auxiliary structure connected thereto is configured to at least partially extend into the cavum concha, cymba concha, triangular fossa and scaphoid, thereby increasing the resistance of the earphone 10 to fall off the ear.

[0042] As an example, in combination Figure 3 In the wearing state, the free end FE of the movement module 11 can extend into the concha cavity. The movement module 11 and the hook structure 12 can be configured to clamp the ear region corresponding to the concha cavity from the front and back sides of the ear region, thereby increasing the resistance of the earphone 10 to fall off the ear, thereby improving the stability of the earphone 10 in the wearing state. For example, the free end FE is pressed in the concha cavity in the thickness direction X; for another example, the free end FE abuts against the concha cavity in the length direction Y and the width direction Z.

[0043] It should be noted that: in the wearing state, the free end FE of the movement module 11 can not only extend into the concha cavity, but also be projected onto the antihelix, or onto the left and right sides of the head and located in front of the ear on the sagittal axis of the human body. In other words, the hook-shaped structure 12 can support the movement module 11 to be worn in the concha cavity, the antihelix, the front of the ear, and other wearing positions.

[0044] As an example, in combination Figure 3 and Figure 4, the movement module 11 may have an inner side surface IS facing the ear and an outer side surface OS away from the ear along the thickness direction X in the wearing state, and a connecting surface connecting the inner side surface IS and the outer side surface OS. The thickness direction X can be defined as the direction in which the movement module 11 approaches or moves away from the ear in the wearing state. Furthermore, at least part of the aforementioned connecting surface is located in the concha cavity in the wearing state, and forms a first contact area with the front side of the above-mentioned ear area, and the hook-shaped structure 12 forms a second contact area with the rear side of the above-mentioned ear area in the wearing state, and the aforementioned second contact area and the aforementioned first contact area at least partially overlap in the ear thickness direction of the above-mentioned ear area. In this way, not only can the movement module 11 and the hook-shaped structure 12 clamp the ear together from the front and back sides of the ear, but the clamping force formed is mainly manifested as compressive stress, which is beneficial to improving the stability and comfort of the earphone 10 in the wearing state.

[0045] It should be noted that: in the wearing state, and observed along the direction of the coronal axis, the movement module 11 can be set to a circular, elliptical, rounded square, rounded rectangle, etc. shape. Among them, when the movement module 11 is set to a circular, elliptical, etc. shape, the above-mentioned connection surface can refer to the arc side of the movement module 11; and when the movement module 11 is set to a rounded square, rounded rectangle, etc. shape, the above-mentioned connection surface can include the lower side LS, upper side US and rear side RS mentioned later. Further, the movement module 11 can have a length direction Y and a width direction Z that are perpendicular to the thickness direction X and orthogonal to each other. Among them, the length direction Y can be defined as the direction in which the movement module 11 approaches or moves away from the back of the user's head in the wearing state, and the width direction Z can be defined as the direction in which the movement module 11 approaches or moves away from the top of the user's head in the wearing state. Therefore, for the convenience of description, this embodiment takes the movement module 11 as a rounded rectangle as an example for exemplary description. The length of the core module 11 in the length direction Y may be greater than the width of the core module 11 in the width direction Z.

[0046] As an example, in combination Figure 2 , Figure 3 and Figure 5, when worn and observed along the direction of the human coronal axis, the connecting end CE is closer to the top of the head than the free end FE, so that the free end FE can extend into the concha cavity. Based on this, the angle between the length direction Y and the direction of the human sagittal axis can be between 15° and 60°. Among them, if the aforementioned angle is too small, it is easy to cause the free end FE to be unable to extend into the concha cavity, and the sound outlet hole 111a on the movement module 11 is too far away from the external auditory canal; if the aforementioned angle is too large, it is also easy to cause the free end FE to be unable to extend into the concha cavity, and the external auditory canal is blocked by the movement module 11. In other words, such a setting allows the free end FE to extend into the concha cavity, and the sound outlet hole 111a on the movement module 11 has a suitable distance from the external auditory canal, so that the user can hear more sound waves generated by the movement module 11 when the external auditory canal is not blocked.

[0047] As an example, in combination Figure 4 The hook-shaped structure 12 is on a reference plane perpendicular to the length direction Y (eg Figure 4 The orthographic projection of the hook-shaped structure 12 on the reference plane (XZ plane) partially overlaps with the orthographic projection of the free end FE on the same reference plane. The overlapping area formed by the orthographic projection of the hook-shaped structure 12 on the aforementioned reference plane and the orthographic projection of the free end FE on the same reference plane is located between the inner side surface IS and the outer side surface OS in the thickness direction X. In this way, not only can the movement module 11 and the hook-shaped structure 12 clamp the ear from the front and back sides of the ear together, but the clamping force formed is mainly manifested as compressive stress, which is conducive to improving the stability and comfort of the earphone 10 when worn.

[0048] Furthermore, combined with Figure 2 , Figure 4 , Figure 5 and Fig. 9 The hook-shaped structure 12 may include an elastic metal wire 121 connected to the movement module 11 and a battery housing 123 connected to an end of the elastic metal wire 121 away from the movement module 11, and a battery 14 coupled to the movement module 11 is arranged in the battery housing 123, and the orthographic projection of the battery housing 123 on the above-mentioned reference plane partially overlaps with the orthographic projection of the free end FE on the same reference plane. In this way, when the free end FE is against the concha cavity, the battery housing 123 can support the ear from the back side of the ear, which is conducive to improving the stability of the earphone 10 in the wearing state. Among them, the battery housing 123 may include a cover shell 1231 connected to the elastic metal wire 121 and a battery compartment 1232 connected to the cover shell 1231, and the battery compartment 1232 and the cover shell 1231 cooperate to form a cavity structure for accommodating the battery 14.

[0049] As an example, in combination Figure 5The core module 11 may have an upper side surface US facing away from the external auditory canal along the width direction Z and a lower side surface LS facing the external auditory canal in the wearing state, and a rear side surface RS connecting the upper side surface US and the lower side surface LS, and the rear side surface RS is located at one end facing the back of the head in the length direction Y in the wearing state, and is at least partially located in the concha cavity. Among them, the hook-shaped structure 12 is perpendicular to the reference plane in the thickness direction X (for example Figure 5 The edge of the orthographic projection on the YZ plane (in the middle) toward the movement module 11 can be divided into a first section S1 and a second section S2 with a continuous arc transition, and the dividing point DP between the first section S1 and the second section S2 is the position where the aforementioned edge is farthest from the upper side US along the width direction Z. Furthermore, the overall bending degree of the hook-shaped structure 12 in the first section S1 is greater than the overall bending degree of the hook-shaped structure 12 in the second section S2. In this way, the free end FE is allowed to extend into the concha cavity, and the hook-shaped structure 12 can cooperate with the movement module 11 to provide a suitable clamping force.

[0050] It should be noted that the above overall curvature can be used to qualitatively describe the curvature of different sections of the hook-shaped structure 12, wherein the curvature radius of each section can be a constant value or continuously variable. Therefore, there is at least one point in the first section S1 whose curvature radius is smaller than the curvature radius of any point in the second section S2. Furthermore, the above overall curvature can also be quantitatively characterized by an average curvature radius, that is, first find the curvature radius of N points on each section and then take the average value.

[0051] Furthermore, in the extension direction of the hook structure 12, the length of the second section S2 can be greater than the length of the first section S1, so that the hook structure 12 and the movement module 11 can clamp the ear together and increase the contact area between the hook structure 12 and the user's skin, which is conducive to improving the stability of the earphone 10 when worn.

[0052] In some embodiments, the earphone 10 has a first reference line segment RL1 parallel to the width direction Z, the starting point of the first reference line segment RL1 is the point where the first reference line segment RL1 intersects with the upper side US, and the end point of the first reference line segment RL1 is the dividing point DP. The second reference line segment RL2, the third reference line segment RL3, and the fourth reference line segment RL4 mentioned later are successively farther and farther away from the starting point of the first reference line segment RL1 in the width direction Z. Further, the length of the first reference line segment RL1 can be between 13 mm and 20 mm. If the length of the first reference line segment RL1 is too small, it is easy to cause the free end FE to be unable to extend into the concha cavity, and the sound outlet 111a on the movement module 11 is too far away from the external auditory canal; if the length of the first reference line segment RL1 is too large, it is also easy to cause the free end FE to be unable to extend into the concha cavity, and the external auditory canal is blocked by the movement module 11. In other words, such a configuration allows the free end FE to extend into the concha cavity, while ensuring that the sound outlet hole 111a on the movement module 11 is at a suitable distance from the external auditory canal, so that the user can hear more sound waves generated by the movement module 11 without blocking the external auditory canal.

[0053] Furthermore, a second reference line segment RL2 passing through 1 / 4 of the first reference line segment RL1 and parallel to the length direction Y intersects the first segment S1 and the second segment S2 at a first intersection point P1 and a second intersection point P2, respectively. The distance between the first intersection point P1 and the starting point of the first reference line segment RL1 may be between 9 mm and 15 mm, and the distance between the second intersection point P2 and the starting point of the first reference line segment RL1 may be between 12 mm and 19 mm. A third reference line segment RL3 passing through 1 / 2 of the first reference line segment RL1 and parallel to the length direction Y intersects the first segment S1 and the second segment S2 at a third intersection point P3 and a fourth intersection point P4, respectively. The third intersection point P1 may be between 9 mm and 15 mm, and the distance between the second intersection point P2 and the starting point of the first reference line segment RL1 may be between 12 mm and 19 mm. The distance between P3 and the starting point of the first reference line segment RL1 can be between 11mm and 18mm, and the distance between the fourth intersection P4 and the starting point of the first reference line segment RL1 can be between 12mm and 19mm; the fourth reference line segment RL4 passing through 3 / 4 of the first reference line segment RL1 and parallel to the length direction Y intersects with the first segment S1 and the second segment S2 at the fifth intersection P5 and the sixth intersection P6 respectively, the distance between the fifth intersection P5 and the starting point of the first reference line segment RL1 can be between 12mm and 19mm, and the distance between the sixth intersection P6 and the starting point of the first reference line segment RL1 can be between 12mm and 19mm. In this way, when the free end FE extends into the concha cavity and the sound outlet 111a on the movement module 11 has a suitable distance from the external auditory canal, the hook structure 12 can better fit the ear.

[0054] In some embodiments, there is a fifth reference line segment RL5 with the shortest spacing along the length direction Y between the second segment S2 and the rear side surface RS, and the length of the fifth reference line segment RL5 can be between 2 mm and 3 mm. If the length of the fifth reference line segment RL5 is too short, it is easy to cause the clamping force of the movement module 11 and the hook structure 12 on the ear to be too large, causing discomfort when wearing; if the length of the fifth reference line segment RL5 is too long, it is easy to cause the clamping force of the movement module 11 and the hook structure 12 on the ear to be too small, causing unstable wearing. In other words, such a setting is to take into account the stability and comfort of the earphone 10 when worn.

[0055] Further, the fifth reference line segment RL5 is defined as follows: the point where the fifth reference line segment RL5 intersects with the rear side surface RS is used as the starting point of the fifth reference line segment RL5, and the point where the fifth reference line segment RL5 intersects with the second segment S2 is used as the end point of the fifth reference line segment RL5. The orthographic projection of the intersection of the first reference line segment RL1 and the upper side surface US along the length direction Y intersects with the second segment S2 at the seventh intersection point P7, the orthographic projection of the intersection of the extension line of the first reference line segment RL1 and the lower side surface LS along the length direction Y intersects with the second segment S2 at the eighth intersection point P8, the distance between the seventh intersection point P7 and the starting point of the fifth reference line segment RL5 can be between 5mm and 9mm, and the distance between the eighth intersection point P8 and the starting point of the fifth reference line segment RL5 can be between 5mm and 9mm. In this way, the hook structure 12 can better fit the ear while taking into account the stability and comfort of the earphone 10 in the wearing state.

[0056] As an example, in combination Figure 7 , Figure 8 and Figure 5 The movement module 11 may include a movement housing 111 connected to the hook structure 12 and a speaker 112 disposed in the movement housing 111. Among them, the movement housing 111 is provided with a sound outlet 111a on the inner side (such as the inner side IS mentioned above) facing the ear in the wearing state, and the sound waves generated by the speaker 112 are propagated through the sound outlet 111a to be transmitted into the external auditory canal. It is worth noting that the sound outlet 111a can also be provided on the side of the movement housing 111 corresponding to the lower side LS, and can also be provided at the corner between the aforementioned inner side and the lower side LS. Furthermore, the speaker 112 may include a magnetic circuit system, a voice coil extending into the magnetic circuit system, and a diaphragm connected to the voice coil. The magnetic field generated after the voice coil is energized interacts with the magnetic field formed by the magnetic circuit system, thereby driving the diaphragm to produce mechanical vibrations, and then generating sound through the propagation of a medium such as air.

[0057] Furthermore, combined with Figures 7 to 9The earphone 10 may include a main control circuit board 13 disposed in the movement housing 111 and a battery 14 disposed at one end of the hook structure 12 away from the movement module 11, and the battery 14 and the speaker 112 are respectively coupled to the main control circuit board 13 to allow the battery 14 to power the speaker 112 under the control of the main control circuit board 13. Of course, the battery 14 and the speaker 112 may also be both disposed in the movement housing 111, and the battery 14 may be closer to the connection end CE and the speaker 112 may be closer to the free end FE.

[0058] As an example, in combination Figure 3 and Figure 1 Since the concha cavity has a certain volume and depth, after the free end FE extends into the concha cavity, there can be a certain distance between the inner side IS of the movement housing 111 and the concha cavity. In other words, the movement module 11 can cooperate with the concha cavity to form an auxiliary cavity connected to the external auditory canal in the worn state, and the sound outlet 111a is at least partially located in the aforementioned auxiliary cavity. In this way, in the worn state, the sound waves generated by the speaker 112 and propagated through the sound outlet 111a will be restricted by the aforementioned auxiliary cavity, that is, the aforementioned auxiliary cavity can gather the sound waves, so that the sound waves can be propagated more into the external auditory canal, thereby increasing the volume and sound quality of the sound heard by the user in the near field, which is conducive to improving the acoustic effect of the earphone 10. Furthermore, since the movement module 11 can be configured not to block the external auditory canal in the worn state, the aforementioned auxiliary cavity can be configured in a semi-open state. In this way, the sound waves generated by the speaker 112 and propagated through the sound outlet 111a, in addition to most of them being propagated to the external auditory canal, a small part is propagated to the earphone 10 and the outside of the ear through the gap between the movement module 11 and the ear (for example, the part of the concha cavity not covered by the movement module 11), thereby forming a first sound leakage in the far field; at the same time, the movement module 11 generally has an acoustic hole (for example, the pressure relief hole 111c mentioned later), and the sound waves propagated through the aforementioned acoustic hole generally form a second sound leakage in the far field, and the phase of the aforementioned first sound leakage and the phase of the aforementioned second sound leakage are (close to) opposite to each other, so that the two can cancel each other out in anti-phase in the far field, which is beneficial to reduce the sound leakage of the earphone 10 in the far field.

[0059] Furthermore, the earphone 10 may include an adjustment mechanism connecting the movement module 11 and the hook structure 12. Different users can adjust the relative position of the movement module 11 on the ear through the adjustment mechanism when wearing the earphone, so that the movement module 11 is located at a suitable position, so that the movement module 11 and the concha cavity form the auxiliary cavity. In addition, due to the existence of the adjustment mechanism, the user can also adjust the earphone 10 to a more stable and comfortable position.

[0060] As an example, in combination Figure 6, first wear the earphone 10 on the simulator, then adjust the position of the movement module 11 on the ear of the simulator, and then measure the frequency response curve of the earphone 10 through a detector (such as a microphone) set in the external auditory canal of the simulator (such as the position of the eardrum, that is, the listening position), so as to simulate the listening effect of the user wearing the earphone 10. Among them, the aforementioned frequency response curve can be used to characterize the changing relationship between the vibration magnitude and the frequency; the abscissa of the aforementioned frequency response curve can represent the frequency, in Hz; the ordinate of the aforementioned frequency response curve can represent the vibration magnitude, in dB. Figure 6 In the figure, curve 6_1 can represent the frequency response curve when the movement module 11 does not form the auxiliary cavity with the concha cavity in the wearing state, and curve 6_2 can represent the frequency response curve when the movement module 11 cooperates with the concha cavity to form the auxiliary cavity in the wearing state. Figure 6 The comparison diagram of the frequency response curves shown can directly and undoubtedly conclude that: curve 6_2 is generally located above curve 6_1, that is, compared with the case where the movement module 11 does not form the above-mentioned auxiliary cavity with the concha cavity when worn, the movement module 11 forms the above-mentioned auxiliary cavity with the concha cavity when worn, which is more conducive to improving the acoustic effect of the earphone 10.

[0061] As an example, in combination Figure 7 , Fig. 9 and Fig.11 , the movement module 11 may include a flexible insert 1131 disposed outside the movement housing 111, and the hardness of the flexible insert 1131 is less than the hardness of the movement housing 111. The movement housing 111 may be a plastic part; the material of the flexible insert 1131 may be silicone, rubber, etc., and may be formed on a preset area of ​​the movement housing 111 by injection molding. Further, the flexible insert 1131 may at least partially cover the area of ​​the movement housing 111 corresponding to the free end FE, so that the movement module 11 at least partially abuts against the cavum concha through the flexible insert 1131. In other words, the portion of the movement housing 111 that extends into the cavum concha and contacts the cavum concha may be covered by the flexible insert 1131. In this way, when the movement module 11 is against the concha cavity, for example, when the movement module 11 and the hook structure 12 are arranged to jointly clamp the aforementioned ear area from the front and back sides of the ear area corresponding to the concha cavity of the ear, the flexible insert 1131 acts as a buffer between the movement housing 111 and the ear (for example, the aforementioned ear area) to relieve the pressure of the earphone 10 on the ear, which is conducive to improving the comfort of the earphone 10 when worn.

[0062] As an example, the flexible insert 1131 can continuously cover at least part of the area of ​​the core shell 111 corresponding to the rear side RS, the upper side US and the lower side LS. For example, the area of ​​the core shell 111 corresponding to the rear side RS is covered by the flexible insert 1131 by more than 90%, and the area of ​​the core shell 111 corresponding to the upper side US and the lower side LS is covered by the flexible insert 1131 by about 30%. In this way, the comfort of the earphone 10 in the wearing state and the need to set structural parts such as the speaker 112 in the core shell 111 are taken into account.

[0063] In some embodiments, when viewed along the thickness direction X, the flexible insert 1131 may be arranged in a U-shape.

[0064] In some embodiments, the portion of the flexible insert 1131 corresponding to the lower side LS can be against the antitragus. The thickness of the portion of the flexible insert 1131 corresponding to the rear side RS can be respectively smaller than the thickness of the portion of the flexible insert 1131 corresponding to the upper side US and the lower side LS, so that good comfort can be obtained when the movement module 11 is against an uneven position in the concha cavity.

[0065] As an example, in combination Figure 7 and Figure 8 The movement housing 111 may include a movement inner housing 1111 and a movement outer housing 1112 that are buckled together along the thickness direction X. The movement inner housing 1111 is closer to the ear than the movement outer housing 1112 when worn. The parting surface 111b between the movement outer housing 1112 and the movement inner housing 1111 is inclined toward the side where the movement inner housing 1111 is located in the direction close to the free end FE, so that the flexible insert 1131 can be arranged as much as possible in the area of ​​the movement outer housing 111 corresponding to the free end FE. For example: Fig.11 The flexible inserts 1131 are all arranged in the area of ​​the movement housing 111 corresponding to the free end FE to simplify the structure of the movement module 11 and reduce the processing cost.

[0066] As an example, in combination Figure 7 , Figure 8 and Fig.11, the movement module 11 may include a flexible coating 1132, the hardness of which is less than that of the movement housing 111. The movement housing 111 may be a plastic part; the material of the flexible coating 1132 may be silicone, rubber, etc., and may be formed on a preset area of ​​the movement housing 111 by injection molding, glue connection, etc. Further, the flexible coating 1132 may be integrally covered on at least part of the outer surface of the flexible insert 1131 and at least part of the outer surface of the movement housing 1112 not covered by the flexible insert 1131, which is conducive to enhancing the consistency of the appearance of the movement module 11. Of course, the flexible coating 1132 may be further covered on the outer surface of the movement inner shell 1111. The hardness of the flexible insert 1131 is less than that of the flexible coating 1132, so as to allow the flexible insert 1131 to be sufficiently soft. In addition, the flexible cover 1132 can also improve the comfort of the earphone 10 when worn, and has a certain structural strength to protect the flexible insert 1131. Furthermore, the area of ​​the outer surface of the flexible insert 1131 can be between 126 mm 2 With 189mm 2 If the aforementioned area is too small, the comfort of the movement module 11 in the wearing state may be deteriorated; if the aforementioned area is too large, the volume of the movement module 11 may be too large, and the area where the flexible insert 1131 does not abut against the concha cavity may be too large, which is contrary to the original intention of providing the flexible insert 1131. Furthermore, the thickness of the flexible coating 1132 is less than the thickness of the movement housing 1112.

[0067] As an example, in combination Fig.11 and Fig. 9, the movement module 11 may include metal functional patterns such as an antenna pattern 1141 and / or a touch pattern 1142 disposed between the movement housing 1112 and the flexible cover 1132. Among them, the antenna pattern 1141 can be formed on the outside of the movement housing 1112 by means of laser direct structuring (LDS); the touch pattern 1142 can be formed on the outside of the movement housing 1112 by means of laser direct structuring technology, or it can be a flexible touch circuit board pasted on the outside of the movement housing 1112. Furthermore, the movement housing 1112 is provided with metallized holes connected to the antenna pattern 1141 and the touch pattern 1142 respectively. At this time, since the main control circuit board 13 is arranged in the core housing 111, for example, the main control circuit board 13 is connected to the core housing 1112, the main control circuit board 13 can contact the inner wall of the corresponding metallized hole through elastic metal parts such as pogo-PIN, metal spring, etc., for example, the antenna pattern 1141 and the touch pattern 1142 are respectively connected to the pogo-PIN 131 and pogo-PIN 132 welded on the main control circuit board 13. Accordingly, the speaker 112 is located on the side of the main control circuit board 13 away from the core housing 1112. In this way, compared with the antenna pattern 1141 and the touch pattern 1142 being respectively arranged on the inner side of the movement housing 1112 facing the speaker 112, the antenna pattern 1141 being arranged on the outer side of the movement housing 1112 can increase the distance between it and the main control circuit board 13, that is, increase the antenna clearance area, thereby increasing the anti-interference ability of the antenna pattern 1141; the touch pattern 1142 being arranged on the outer side of the movement housing 1112 can shorten the distance between it and the external signal trigger source (such as the user's finger), that is, reduce the touch distance, thereby increasing the sensitivity of the touch pattern 1142 being triggered by the user.

[0068] In some embodiments, the antenna pattern 1141 may surround the periphery of the touch pattern 1142 to fully utilize the space outside the core housing 1112. The antenna pattern 1141 may be arranged in a U-shape, and the touch pattern 1142 may be arranged in a square shape.

[0069] Furthermore, the core module 11 may include a microphone 133 welded on the main control circuit board 13, and the microphone 133 may pick up user voice and ambient sound through a sound pickup through hole provided on the core housing 1112. When the main control circuit board 13 is connected to the core housing 1112, the microphone 133 may be further pressed against the core housing 1112.

[0070] As an example, in combination Fig.10 and Fig.11The inner shell 1111 of the movement may include a bottom wall 1113 and a first side wall 1114 connected to the bottom wall 1113, and the outer shell 1112 of the movement may include a top wall 1115 and a second side wall 1116 connected to the top wall 1115, and the second side wall 1116 and the first side wall 1114 are buckled with each other along the parting surface 111b, and the two can support each other. Wherein, when viewed along the width direction Z, and in the reference direction from the connection end CE to the free end FE (for example Fig.10 and Fig.11 In the opposite direction of the arrow Y in the middle), the portion of the first side wall 1114 close to the free end FE gradually approaches the bottom wall 1113 in the thickness direction X, and the portion of the second side wall 1116 close to the free end FE gradually moves away from the top wall 1115 in the thickness direction X, so that the split mold surface 111b is inclined toward the side where the movement inner shell 1111 is located in the direction close to the free end FE. At this time, the flexible insert 1131 is at least partially arranged on the outside of the second side wall 1116. For example: Fig.11 and Fig. 9 In addition to being arranged on the outside of the second side wall 1116, the flexible insert 1131 is also partially arranged on the outside of the top wall 1115. Accordingly, the sound outlet hole 111a can be arranged on the bottom wall 1113. Of course, the sound outlet hole 111a can also be arranged on the side of the first side wall 1114 corresponding to the lower side surface LS, and can also be arranged at the corner between the first side wall 1114 and the bottom wall 1113. Further, the antenna pattern 1141 and the touch pattern 1142 and their respective metallized holes can be arranged on the top wall 1115, and the pickup through hole of the microphone 133 can also be arranged on the top wall 1115.

[0071] As an example, in combination Figure 7 and Fig.11 The movement housing 1112 may be provided with an embedding groove at least partially located on the second side wall 1116, and the flexible insert 1131 is embedded in the aforementioned embedding groove, so that the outer surface of the region of the movement housing 1112 not covered by the flexible insert 1131 is continuously transitioned to the outer surface of the flexible insert 1131. Figure 7 The area where the middle flexible insert 1131 is located can be simply regarded as the aforementioned embedding groove. In this way, it is not only beneficial for the flexible insert 1131 to be accumulated on the movement housing 1112 during the injection molding process to prevent the flexible insert 1131 from overflowing, but also beneficial for improving the appearance quality of the movement module 11 and preventing the surface of the movement module 11 from being bumpy.

[0072] Further, the second side wall 1116 may include a first sub-side wall segment 1117 and a second sub-side wall segment 1118 connected to the first sub-side wall segment 1117, the first sub-side wall segment 1117 is closer to the top wall 1115 than the second sub-side wall segment 1118 in the thickness direction X, and the second sub-side wall segment 1118 protrudes toward the outside of the movement housing 111 compared to the first sub-side wall segment 1117. In short, the second side wall 1116 may have a stepped structure. In this way, it is not only beneficial for the flexible insert 1131 to be accumulated on the movement housing 1112 during the injection molding process to avoid overflowing of the flexible insert 1131, but also beneficial for the movement module 11 to better abut against the concha cavity through the flexible insert 1131, thereby improving the comfort of the earphone 10 when worn.

[0073] Furthermore, the main control circuit board 13 can be connected to the core housing 1112, for example, fixed on a hot melt column connected to the top wall 1115, and can partially overlap with the first sub-side wall section 1117 in the thickness direction X; the speaker 112 can partially overlap with the second sub-side wall section 1118 in the thickness direction X. In this way, it is beneficial to set a sufficiently large speaker 112 in the core housing 111, thereby enhancing the sound volume produced by the earphone 10.

[0074] As an example, in combination Fig.10 and Figure 8 , the movement housing 111 may be provided with a pressure relief hole 111c, and the pressure relief hole 111c enables the space on the side of the speaker 112 facing the main control circuit board 13 to be connected to the external environment, that is, the air can freely enter and exit the aforementioned space. In this way, it is helpful to reduce the resistance of the diaphragm of the speaker 112 during the vibration process. Among them, the pressure relief hole 111c can be facing the top of the head when worn, which is helpful to avoid the sound waves propagating through the pressure relief hole 111c from leaking sound (that is, the above-mentioned second leakage sound) being heard. Based on the Helmholtz resonance cavity, the aperture of the pressure relief hole 111c can be as large as possible, so that the resonant frequency of the second leakage sound is shifted to a higher frequency band (for example, a frequency range greater than 4kHz) as much as possible, which is helpful to further avoid the second leakage sound being heard.

[0075] Furthermore, the movement housing 111 may be provided with a tuning hole 111d, and the tuning hole 111d makes the resonance frequency of the second sound leakage shift to a higher frequency band (for example, a frequency range greater than 4kHz) as much as possible, which is conducive to further avoiding the second sound leakage from being heard. Among them, the area of ​​the tuning hole 111d may be smaller than the area of ​​the pressure relief hole 111c, so that the space on the side of the speaker 112 facing the main control circuit board 13 is more connected to the external environment through the pressure relief hole 111c. Furthermore, the spacing between the sound outlet hole 111a and the pressure relief hole 111c in the width direction Z is greater than the spacing between the sound outlet hole 111a and the tuning hole 111d in the width direction Z, so as to avoid the sound waves propagated through the sound outlet hole 111a and the pressure relief hole 111c respectively from canceling each other out in the near field, which is conducive to increasing the volume of the sound propagated through the sound outlet hole 111a heard by the user. Accordingly, the sound tuning hole 111d is closer to the connection end CE than the sound outlet hole 111a to increase the distance between the two in the length direction Y, thereby avoiding the anti-phase cancellation of the sound waves propagated through the sound outlet hole 111a and the sound tuning hole 111d in the near field, which is beneficial to increase the volume of the sound propagated through the sound outlet hole 111a heard by the user.

[0076] As an example, in combination Fig.10 , the sound outlet hole 111a, the pressure relief hole 111c and the sound adjustment hole 111d can be arranged on the movement inner shell 1111, for example, the sound outlet hole 111a is arranged on the bottom wall 1113 and the pressure relief hole 111c and the sound adjustment hole 111d are respectively arranged on the first side wall 1114. Among them, the pressure relief hole 111c and the sound adjustment hole 111d can be respectively arranged on the opposite sides of the first side wall 1114 along the width direction Z. In this way, since the sound outlet hole 111a, the pressure relief hole 111c and the sound adjustment hole 111d are all arranged on the movement inner shell 1111, the structure of the movement outer shell 1112 is simpler, which is conducive to reducing the processing cost. In addition, since the pressure relief hole 111c and the sound adjustment hole 111d are respectively arranged on the opposite sides of the first side wall 1114 along the width direction Z, the above-mentioned parting surface 111b can be symmetrically arranged about a reference plane perpendicular to the width direction Z, which is conducive to improving the appearance quality of the movement module 11.

[0077] As an example, in combination Figure 7 and Figure 8The movement module 11 may include a bracket 115 disposed in the movement housing 111. The bracket 115 and the speaker 112 may be arranged to form an acoustic cavity 116, so that the acoustic cavity 116 is separated from other structures in the movement housing 111 (such as the main control circuit board 13, etc.), which is conducive to improving the acoustic performance of the movement module 11. Among them, the movement housing 111 is provided with an acoustic hole, for example, the acoustic hole is at least one of the pressure relief hole 111c and the sound adjustment hole 111d, and the bracket 115 is provided with an acoustic channel 1151 connecting the acoustic hole and the acoustic cavity 116, so that the acoustic cavity 116 is connected to the external environment, that is, the air can freely enter and exit the acoustic cavity 116, which is conducive to reducing the resistance of the diaphragm of the speaker 112 during the vibration process.

[0078] Furthermore, the bracket 115 cooperates with the movement housing 111 to form a first glue groove 1171 surrounding at least a portion of the acoustic hole. The first glue groove 1171 contains a first glue for sealing the assembly gap between the bracket 115 and the movement housing 111, that is, waterproof sealing is performed by the first glue, which is conducive to preventing external sweat, rainwater and other droplets from invading the space where the main control circuit board 13 is located in the movement housing 111. In this way, based on the Helmholtz resonance cavity, compared with the related art that a silicone sleeve is pressed on the movement housing 111 by the bracket 115 for waterproof sealing, the present technical solution uses the first glue for waterproof sealing, which can save the aforementioned silicone sleeve in the related art, and is conducive to shortening the length of the part of the acoustic cavity 116 that is connected to the external environment (including the acoustic channel 1151 and the acoustic hole), so that the resonance frequency of the leakage sound (that is, the second leakage sound) formed by propagating through the pressure relief hole 111c is shifted to a higher frequency band (for example, a frequency range greater than 4kHz) as much as possible, thereby further preventing the second leakage sound from being heard.

[0079] It should be noted that: when the acoustic hole is a pressure relief hole 111c, the first adhesive groove 1171 surrounds at least a portion of the pressure relief hole 111c; when the acoustic hole is a sound tuning hole 111d, the first adhesive groove 1171 surrounds at least a portion of the sound tuning hole 111d; when the acoustic holes are a pressure relief hole 111c and a sound tuning hole 111d, the first adhesive groove 1171 surrounds at least a portion of the pressure relief hole 111c and the sound tuning hole 111d, respectively. Figure 8 , Fig.10 and Fig.12, the present application takes the acoustic holes as the pressure relief hole 111c and the sound adjustment hole 111d, and the first glue containing groove 1171 surrounds at least a part of the pressure relief hole 111c and the sound adjustment hole 111d respectively as an example for exemplary description. Further, if the gap between the bracket 115 and the movement housing 111 (for example, its bottom wall 1113) is large enough, or the bottom wall 1113 and the first side wall 1114 in the movement housing 111 are not an integrally formed structural part (that is, two separate structural parts), then the first glue containing groove 1171 can surround all of the acoustic holes, that is, the first glue containing groove 1171 is a complete annular structure.

[0080] As an example, in combination Fig.12 and Fig.10 , the bracket 115 may include an annular main body 1152 and a docking portion 1153 connected to the annular main body 1152. The annular main body 1152 is sleeved on the periphery of the speaker 112 to form an acoustic cavity 116, and the acoustic channel 1151 runs through the docking portion 1153 and the annular main body 1152. Further, the docking portion 1153 is located between the annular main body 1152 and the movement shell 111, and surrounds at least a portion of the above-mentioned acoustic hole, and the docking portion 1153 cooperates with the movement shell 111 to form a first glue containing groove 1171. Since the above-mentioned acoustic hole can be a pressure relief hole 111c and a sound adjustment hole 111d, two docking portions 1153 are correspondingly provided, and two first glue containing grooves 1171 are also correspondingly provided. Correspondingly, the docking portion 1153 cooperates with the first side wall 1114 to form the first glue containing groove 1171. In this way, since the bracket 115 is arranged in a ring shape, the speaker 112 is exposed toward the side of the main control circuit board 13, which is conducive to reducing the thickness of the movement module 11 in the thickness direction X.

[0081] As an example, in combination Fig.10 and Figure 8, a recessed area 1119 may be provided on the inner side of the movement housing 111, the acoustic hole may be provided at the bottom of the recessed area 1119, the movement module 11 may include an acoustic resistance net 118 provided in the recessed area 1119, and the docking portion 1153 presses the acoustic resistance net 118 on the bottom of the recessed area 1119. In this way, it is not only beneficial to prevent the bracket 115 from scraping the acoustic resistance net 118 during the assembly process, but also beneficial to reduce the assembly gap between the bracket 115, the acoustic resistance net 118 and the movement inner shell 1111, and to prevent the acoustic resistance net 118 from shaking. Among them, the acoustic resistance net 118 may be pre-fixed at the bottom of the recessed area 1119 by double-sided tape or glue; the acoustic resistance net 118 may also be pre-fixed on the protective steel net first, and the aforementioned protective steel net is then pre-fixed at the bottom of the recessed area 1119 by double-sided tape or glue. Correspondingly, since the above-mentioned acoustic holes can be the pressure relief hole 111c and the sound adjustment hole 111d, two recessed areas 1119 are correspondingly provided, and two acoustic resistance nets 118 are also correspondingly provided.

[0082] Furthermore, the first glue can be further used to seal the assembly gap between the bracket 115 and the acoustic resistance net 118 and / or the assembly gap between the acoustic resistance net 118 and the movement housing 111 (such as the side wall of the recessed area 1119), which is conducive to further waterproof sealing.

[0083] As an example, in combination Figure 8 , Fig.10 and Fig.12 , the docking portion 1153 can be used to form the bottom wall and one side wall of the first glue containing groove 1171, and the movement shell 111 can be used to form the other side wall of the first glue containing groove 1171. Among them, the groove wall on the movement shell 111 and the groove wall on the docking portion 1153 are arranged opposite to each other, so that the first glue containing groove 1171 has a certain width and depth. Of course, the docking portion 1153 can be used to form one side wall of the first glue containing groove 1171, and the movement shell 111 can be used to form the bottom wall and the other side wall of the first glue containing groove 1171; or, the docking portion 1153 can be used to form one side wall of the first glue containing groove 1171 and a part of the bottom wall, and the movement shell 111 can be used to form the other side wall of the first glue containing groove 1171 and another part of the bottom wall.

[0084] As an example, in combination Figure 12 to Figure 14The speaker 112 may include a body 1121 and an annular support 1122 arranged along the circumference of the body 1121. The lower end of the bracket 115 may be supported on the annular support 1122. The acoustic channel 1151 may be open-type on the side facing the annular support 1122. The annular support 1122 further blocks the open part of the acoustic channel 1151. At this time, the first glue groove 1171 may be simply regarded as a part surrounding the acoustic hole, so as to facilitate the subsequent use of glue filling in the first glue groove 1171 by methods such as glue dispensing process.

[0085] In some embodiments, the annular platform 1122 may include a first annular table 1123 and a second annular table 1124 arranged in a stepped shape, and the second annular table 1124 is arranged around the periphery of the first annular table 1123; a portion of the lower end of the bracket 115 can be supported on the first annular table 1123, and another portion of the lower end of the bracket 115 can form a spacing area with the second annular table 1124, so that the bracket 115, the annular platform 1122 and the movement shell 111 cooperate to form a second glue groove 1172, and the second glue groove 1172 contains a second glue for sealing the assembly gap between any two of the bracket 115, the annular platform 1122 and the movement shell 111 to perform corresponding waterproof sealing.

[0086] In some embodiments, the upper end of the bracket 115 can be placed on the body 1121 and cooperate with the body 1121 to form a third glue groove 1173, which contains a third glue for sealing the assembly gap between the bracket 115 and the body 1121 to perform corresponding waterproof sealing.

[0087] It should be noted that: in the specific assembly process of the movement module 11, the following process steps may be included, and the order of all process steps may be adjusted as needed: 1) pre-fix the acoustic resistance net 118 at the bottom of the recessed area 1119 by double-sided adhesive; 2) fix the speaker 112 on the bottom wall 1113, and dispense glue to the assembly gap between the two, and the corresponding glue portion is accumulated on the second annular table 1124 of the speaker 112; 3) before the glue in step 2) is cured, fix the bracket 115 on the speaker 112, wherein the lower end of the bracket 115 supports On the first annular table 1123 of the speaker 112, the space between the lower end of the bracket 115 and the second annular table 1124 is also filled with glue, the docking portion 1153 of the bracket 115 presses the acoustic resistance net 118, and cooperates with the first side wall 1114 to form a first glue groove 1171, the upper end of the bracket 115 is placed on the main body 1121, and cooperates with the main body 1121 to form a third glue groove 1173; 4) Glue is applied to the first glue groove 1171, the third glue groove 1173 and the assembly gap between the lower end of the bracket 115 and the speaker 112 and the movement inner shell 1111. Among them, since the assembly gap between the lower end of the bracket 115 and the speaker 112 and the movement inner shell 1111 is very close to the first glue groove 1171, the assembly gap between the lower end of the bracket 115 and the speaker 112 and the movement inner shell 1111 can be simply regarded as a continuation of the first glue groove 1171, that is, the first glue groove 1171 and the second glue groove 1172 can be connected.

[0088] As an example, in combination Figures 15 to 18 and Figure 7 , the hook-shaped structure 12 may include a transfer housing 122 connected to the movement module 11, the transfer housing 122 may be pre-formed with a receiving cavity 124, and the earphone 10 may include an electronic component 15 subsequently installed in the receiving cavity 124. Among them, the connection method between the transfer housing 122 and the movement module 11 may be one or a combination of assembly methods such as snap connection, welding, glue connection, threaded connection and screw connection. In this way, compared with the electronic component 15 being arranged in the movement module 11 in the related art, the present technical solution not only helps to save the space of the movement module 11 and make it more compact and small in structure, but also helps to simplify the structure of the movement module 11 and make it more efficient to assemble, and also helps to reasonably arrange the relative positions of various structural components in the earphone 10, so that both the movement module 11 and the hook-shaped structure 12 can be fully utilized.

[0089] It should be noted that: the adapter shell 122 is pre-formed with a accommodating cavity 124, which may mean that the accommodating cavity 124 is formed at the same time when the adapter shell 122 is molded, rather than being formed by processing after the adapter shell 122 is molded. For example: the adapter shell 122 is a plastic shell, and the corresponding accommodating cavity 124 can be obtained after the plastic shell is injection molded by setting a corresponding core. Correspondingly, the subsequent installation of the electronic component 15 in the accommodating cavity 124 may refer to the electronic component 15 and the adapter shell 122 being non-integrally molded structural parts. For example: the adapter shell 122 is a plastic shell, and the electronic component 15 is not integrally injection molded in the plastic shell by means of an insert. Based on this, the description of the adapter shell 122 pre-formed with a through hole 1251, a blind hole 1252 and a through hole 1253 mentioned in the following text is the same or similar to this, and will not be repeated here. Of course, the accommodating cavity 124 can also be obtained by means of a drilling process after the adapter shell 122 is formed, and the through hole 1251, the blind hole 1252 and the through hole 1253 can also be obtained by means of a drilling process after the adapter shell 122 is formed.

[0090] As an example, in combination Figure 7 , the electronic component 15 can be coupled with the main control circuit board 13 to realize the electrical connection between the hook structure 12 and the movement module 11, and the adapter housing 122 can be plugged and fixed with the movement housing 111 to realize the structural connection between the hook structure 12 and the movement module 11, which is simple and reliable. Among them, the aforementioned plug-in fixation can refer to that one of the adapter housing 122 and the movement housing 111 first partially extends into the other along the assembly direction and then is plugged and fixed with the help of other limiting structures such as latches, and the assembly direction of the aforementioned limiting structure is not parallel to the aforementioned assembly direction; the aforementioned plug-in fixation can also refer to that when one of the adapter housing 122 and the movement housing 111 partially extends into the other, it can be plugged and fixed without the help of the aforementioned limiting structure.

[0091] As an example, in combination Figure 7 , Fig.10 and Fig.16 , the transfer housing 122 may be provided with a first snap-fit ​​structure 1221, and the core housing 111 may be provided with a second snap-fit ​​structure 1222, the first snap-fit ​​structure 1221 extends into the core housing 111, and is snap-fitted with the second snap-fit ​​structure 1222, so that the transfer housing 122 and the core housing 111 are snap-fitted and fixed, and the two are directly plugged and fixed without the aid of other limiting structures, which is simple and reliable. Among them, the first snap-fit ​​structure 1221 may be integrally provided on the transfer housing 122, and two may be relatively spaced apart in the thickness direction X; the second snap-fit ​​structure 1222 may be integrally provided on the core inner shell 1111, and is provided one-to-one with the first snap-fit ​​structure 1221.

[0092] As an example, in combination Figure 7The earphone 10 may include a flexible circuit board 16, which may be at least partially disposed in the accommodating cavity 124 to connect with the electronic component 15 and extend into the movement housing 111, so that the electronic component 15 is connected to the main control circuit board 13 through the flexible circuit board 16. For example, the electronic component 15 is welded to one end of the flexible circuit board 16 by means of surface mount technology (SMT), and the other end of the circuit board of the flexible circuit board 16 and the main control circuit board 13 are buckled by means of a BTB connector. Among them, the speaker 112 may be arranged to be connected to the flexible circuit board 16 on the extension path of the flexible circuit board 16, for example, the lead of the speaker 112 is welded on the corresponding area of ​​the flexible circuit board 16, so that the speaker 112 is also connected to the main control circuit board 13 through the flexible circuit board 16, so that the lead of the speaker 112 does not need to be extended to connect with the main control circuit board 13, which is conducive to simplifying the wiring structure of the earphone 10 and reducing the production cost.

[0093] As an example, in combination Fig.16 and Fig.15 , the adapter shell 122 may be pre-formed with a through hole 1251 that is connected to the accommodating cavity 124, and the electronic component 15 may include an electrode terminal 151 that is at least partially disposed in the through hole 1251. The electrode terminal 151 may be a retractable elastic component such as a pogo-PIN, or a non-retractable rigid component such as a metal column. Among them, the aperture of the through hole 1251 may be larger than the outer diameter of the electrode terminal 151 to facilitate the subsequent installation of the electrode terminal 151. Of course, the electrode terminal 151 may also be integrally formed with the adapter shell 122 in the form of an insert. Furthermore, the electrode terminal 151 may be oriented toward the ear in the worn state, so that it is invisible in the worn state, which is conducive to improving the appearance quality of the headset 10 in the worn state.

[0094] It should be noted that: when the electrode terminal 151 is set as a retractable elastic component such as a pogo-PIN, the extension direction of the electrode terminal 151 can be its retractable direction; and when the electrode terminal 151 is set as a non-retractable rigid component such as a metal column, the extension direction of the electrode terminal 151 can be the direction of its axis.

[0095] Furthermore, a plurality of electrode terminals 151 may be provided according to actual usage requirements, for example, for charging, detection, etc.

[0096] In some embodiments, the electrode terminal 151 may include a positive charging terminal 1511 and a negative charging terminal 1512 that are spaced apart from each other, and the positive charging terminal 1511 and the negative charging terminal 1512 may be respectively disposed in respective through holes 1251, so that the earphone 10 can be charged through the electrode terminal 151. Of course, only one of the positive charging terminal 1511 and the negative charging terminal 1512 may be disposed on the adapter housing 122, and the other may be disposed on other housings in the hook structure 12, such as the battery housing 123, or on the movement inner housing 1111.

[0097] In some embodiments, the electrode terminal 151 may include a detection terminal 1513 spaced apart from the positive charging terminal 1511 and the negative charging terminal 1512, and the detection terminal 1513 may be used to perform detection functions such as charging detection, detection of the earphone 10 being placed in or taken out of the charging box, etc. Of course, the detection terminal 1513 may also be replaced by an electronic component such as a Hall sensor.

[0098] In some embodiments, when viewed along the extension direction of the electrode terminal 151 , the connecting lines between the positive charging terminal 1511 , the negative charging terminal 1512 , and the detection terminal 1513 may form a triangle, such as an equilateral triangle.

[0099] In some embodiments, when viewed along the extension direction of the electrode terminal 151, the positive charging terminal 1511, the negative charging terminal 1512, and the detection terminal 1513 can be arranged in a line segment spaced apart from each other, for example, in a straight line segment. Among them, the distance between the positive charging terminal 1511 and the negative charging terminal 1512 can be greater than the distance between the negative charging terminal 1512 and the detection terminal 1513. For example, the negative charging terminal 1512 is located between the positive charging terminal 1511 and the detection terminal 1513, and the distance between the positive charging terminal 1511 and the negative charging terminal 1512 is greater than the distance between the negative charging terminal 1512 and the detection terminal 1513; for another example, the detection terminal 1513 is located between the positive charging terminal 1511 and the negative charging terminal 1512. In this way, when the space for setting the electrode terminal 151 on the adapter housing 122 is limited, the distance between the positive charging terminal 1511 and the negative charging terminal 1512 is increased as much as possible, which is conducive to avoiding a short circuit between the two.

[0100] As an example, in combination Fig.15, a boss 126 may be provided on the outside of the transfer housing 122, and a through hole 1251 further penetrates the boss 126, so that a plurality of electrode terminals 151 are exposed at the boss 126. In this way, the boss 126 makes the uneven part of the transfer housing 122 due to a certain curvature become flat, so as to facilitate the arrangement of the electrode terminal 151. Among them, the positive charging terminal 1511, the negative charging terminal 1512 and the detection terminal 1513 may be arranged in sequence along the length direction of the boss 126.

[0101] As an example, in combination Figures 15 to 17 , the hook structure 12 may include a magnet 127, and the magnet 127 and the electrode terminal 151 may be exposed on the same side of the transfer housing 122, that is, both may be visible on the same side surface of the transfer housing 122, so that the magnet 127 is closer to the outside world to which the exposed end of the electrode terminal 151 faces, thereby shortening the distance between the magnet 127 and the magnetic attraction structure used to cooperate with the magnet 127 in a charging device such as a charging box, or the distance between the Hall sensor used to cooperate with the magnet 127, which is conducive to improving the reliability of functions such as charging and detection. Among them, the magnet 127 and the electrode terminal 151 may be arranged adjacent to each other to allow the magnet 127 to cooperate with the magnetic attraction structure in a charging device such as a charging box, so that the electrode terminal 151 cooperates with the electrode terminal in the charging device to facilitate charging. Accordingly, the boss 126 may protrude from the transfer housing 122 around the magnet 127, that is, the magnet 127 may be lower than the boss 126, so that the electrode terminal 151 can contact the electrode terminal in a charging device such as a charging box. Of course, in an implementation where the magnet 127 is used in conjunction with a Hall sensor in a charging device such as a charging box for detection, the magnet 127 is disposed adjacent to the electrode terminal 151, and the electrode terminal in a charging device such as a charging box that is used to cooperate with the electrode terminal 151 can also be disposed adjacent to the aforementioned Hall sensor. This is beneficial in reducing the area in a charging device such as a charging box that is used to carry the aforementioned electrode terminal and the aforementioned Hall sensor.

[0102] Further, the hook structure 12 may include a flexible coating 128, and the hardness of the flexible coating 128 is less than the hardness of the adapter shell 122. Among them, the adapter shell 122 may be a plastic part; the material of the flexible coating 128 may be silicone, rubber, etc., and may be formed on the adapter shell 122 by injection molding, glue connection, etc. Further, the flexible coating 128 may cover the adapter shell 122 and the magnet 127, so that the magnet 127 is not exposed and the electrode terminal 151 is exposed, that is, the magnet 127 is invisible and the electrode terminal 151 is visible. In this way, the use requirements of the electrode terminal 151 can be met, and the magnet 127 can be shielded to prevent it from being exposed and worn or affecting the appearance quality. In addition, the flexible coating 128 is also conducive to improving the comfort of the earphone 10 when wearing. Among them, the thickness of the flexible coating 128 is less than the thickness of the adapter shell 122.

[0103] As an example, in combination Fig.16 The adapter housing 122 may be pre-formed with a blind hole 1252 that is not connected to the accommodating chamber 124, so as to increase the waterproof and dustproof performance of the accommodating chamber 124. The magnet 127 may be at least arranged in the blind hole 1252 and exposed through the open end of the blind hole 1252. In this way, it is not only helpful to reduce the thickness of the adapter housing 122 in the area where the magnet 127 is located, but also helpful to improve the appearance quality of the earphone 10 in the area where the magnet 127 is located. Of course, the blind hole 1252 may also be set as a through hole.

[0104] As an example, in combination Fig.15 , along the extension direction of the electrode terminal 151, the plurality of electrode terminals 151 may be arranged at intervals to form a line segment, such as a straight line segment or a broken line segment. Among them, the magnet 127 may be located on any side of the aforementioned line segment, or the magnet 127 intersects with the aforementioned line segment and is at least partially located between any two adjacent electrode terminals 151. For example: the number of magnets 127 is one, and the magnet 127 is located on one side of the aforementioned line segment as a whole, or intersects with the aforementioned line segment and is located between any two adjacent electrode terminals 151 as a whole. For another example: the number of magnets 127 is two, one magnet 127 is located on one side of the aforementioned line segment as a whole, and the other magnet 127 is located on the other side of the aforementioned line segment as a whole. For another example: the number of magnets 127 is one, a part of the magnet 127 intersects with the aforementioned line segment and is located between any two adjacent electrode terminals 151, and the other part is located below the electrode terminal 151 in the aforementioned extension direction.

[0105] As an example, in combination Fig.15, the plurality of electrode terminals 151 may include a charging positive terminal 1511, a charging negative terminal 1512 and a detection terminal 1513 arranged in a straight line segment. Among them, the magnet 127 may be located on one side of the aforementioned straight line segment. Further, along the extension direction of the electrode terminal 151, the center of the magnet 127 has a first distance, a second distance and a third distance from the center of the charging positive terminal 1511, the charging negative terminal 1512 and the detection terminal 1513, respectively, and the third distance is greater than the first distance and the second distance, respectively, to prioritize the reliability of charging. It is worth noting that: in the embodiment in which the hook-shaped structure 12 is provided with a flexible coating 128, in order to facilitate the determination of the relative position relationship between the magnet 127, the charging positive terminal 1511, the charging negative terminal 1512 and the detection terminal 1513, the flexible coating 128 can be removed first.

[0106] As an example, in combination Figures 16 to 18 , the electronic component 15 may include an electrode terminal 151 and a microphone 152, and the adapter shell 122 may be pre-formed with a through hole 1251 and a through hole 1253 that are connected to the accommodating cavity 124, and are respectively connected to the accommodating cavity 124. Among them, due to the different functions of the electrode terminal 151 and the microphone 152, the through hole 1251 and the through hole 1253 may be located on different side walls of the adapter shell 122. Based on this, the electrode terminal 151 may be at least partially disposed in the through hole 1251, and the microphone 152 may be disposed in the accommodating cavity 124, and pick up the sound outside the earphone 10 (such as user voice, environmental sound) through the through hole 1253. In this way, by reasonably arranging the relative positions of the electrode terminal 151 and the microphone 152, the space of the accommodating cavity 124 can be fully utilized, and the structure of the earphone 10 is therefore more compact and small. Furthermore, the earphone 10 may include a support assembly 17 at least partially disposed in the accommodating cavity 124, and the support assembly 17 may respectively support and fix the electrode terminal 151 and the microphone 152 on the side walls corresponding to the through hole 1251 and the through hole 1253. In this way, it is not only helpful to prevent the electrode terminal 151 and the microphone 152 from being separated from the adapter housing 122, but also helpful to increase the waterproof and dustproof performance of the electronic component 15, and the structure is simple and reliable.

[0107] As an example, in combination Fig.18, the flexible circuit board 16 may include a first circuit board portion 161, a second circuit board portion 162 and a third circuit board portion 163 of an integrated structure, the electrode terminal 151 is welded to the first circuit board portion 161, the second circuit board portion 162 is bent relative to the first circuit board portion 161, and the microphone 152 is welded to the third circuit board portion 163 and bent relative to the second circuit board portion 162. In other words, after the flexible circuit board 16 is bent twice, the first circuit board portion 161, the second circuit board portion 162 and the third circuit board portion 163 may correspond to three adjacent sides of the hexagonal structure. Among them, one end of the second circuit board portion 162 away from the third circuit board portion 163 is connected to the first circuit board portion 161, and the other parts are not connected to the first circuit board portion 161. In this way, after the flexible circuit board 16 and the electrode terminals 151 and the microphone 152 thereon are assembled in the adapter shell 122, the operator is allowed to first press the end of the second circuit board portion 162 connected to the first circuit board portion 161 to make it as flush as possible with the first circuit board portion 161 to avoid the support component 17 that is assembled subsequently.

[0108] In some embodiments, the transfer housing 122 may include two housings whose parting surfaces are perpendicular to the extension direction of the electrode terminal 151, and the two housings are buckled together to form a receiving cavity 124. The support assembly 17 may be integrally formed with one of the housings to respectively support (or press) the electrode terminal 151 and the microphone 152 when the two housings are buckled together. Alternatively, at least one of the first support member for supporting the electrode terminal 151 and the second support member for supporting the microphone 152 in the support assembly 17 may be independent of the transfer housing 122 to respectively support (or press) the electrode terminal 151 and the microphone 152 when the two housings are buckled together, or the support assembly 17 may be assembled after the two housings are buckled together to respectively support (or press) the electrode terminal 151 and the microphone 152.

[0109] In some embodiments, at least the portion of the adapter housing 122 corresponding to the accommodating cavity 124 is a complete housing structure. Among them, at least the first support member of the support assembly 17 for supporting the electrode terminal 151 and the second support member for supporting the microphone 152 can be independent of the adapter housing 122 to at least facilitate the assembly of the electrode terminal 151.

[0110] As an example, in combination Fig.18 , the support assembly 17 can be independent of the transfer housing 122 and inserted into the accommodating cavity 124. In this way, since the support assembly 17, the electrode terminal 151 and the microphone 152 can be independent of the transfer housing 122, they can be assembled in a certain sequence, which is conducive to avoiding unnecessary interference in the structure and making the assembly efficiency higher.

[0111] In some embodiments, the first support member for supporting the electrode terminal 151 and the second support member for supporting the microphone 152 in the support assembly 17 can be independent of the adapter housing 122, that is, the first support member and the second support member are independent of each other to respectively support (or press) the electrode terminal 151 and the microphone 152. In this way, the first support member and the second support member in the support assembly 17 can be designed differently according to actual needs.

[0112] In some embodiments, the support assembly 17 can be an integrally formed structural member, that is, the first support member for supporting the electrode terminal 151 and the second support member for supporting the microphone 152 in the support assembly 17 are connected to each other, which is not only conducive to simplifying the structure of the support assembly 17, but also conducive to avoiding the first support member and the second support member being too small to be difficult to assemble. Among them, the support assembly 17 can be tightly fixed with the cavity wall of the accommodating cavity 124 after being inserted into place, that is, the support assembly 17 has a certain damping during the insertion or removal process, and the structure is simple and reliable. Correspondingly, the cavity wall of the accommodating cavity 124 can be provided with guide grooves and limit grooves that cooperate with the support assembly 17. Of course, the support assembly 17 can be further glued to the cavity wall of the accommodating cavity 124 by means of a glue dispensing process.

[0113] As an example, in combination Fig.17 and Fig.18 , at least part of the support assembly 17 and the accommodating cavity 124 are perpendicular to the insertion direction of the support assembly 17 relative to the accommodating cavity 124 (for example Fig.17 and Fig.18 The dimension in at least one reference direction (the direction indicated by the arrow in the middle) can be set to gradually decrease along the aforementioned insertion direction, so that the support component 17 can be extended into the spacing area between the electrode terminal 151 and the microphone 152. In other words, the dimension of at least part of the support component 17 in at least one reference direction perpendicular to the aforementioned insertion direction can be set to gradually decrease along the aforementioned insertion direction, and the dimension of at least part of the accommodating cavity 124 in the same reference direction can be set to gradually decrease along the aforementioned insertion direction, and the change trends of the two are the same or similar, which is conducive to the support component 17 being tightly matched and fixed with the cavity wall of the accommodating cavity 124 after being inserted into place.

[0114] As an example, in combination Figures 16 to 18, the cavity wall of the accommodating cavity 124 may include a first cavity wall 1241 and a second cavity wall 1242 arranged side by side and spaced apart from each other, and a third cavity wall 1243 connecting the first cavity wall 1241 and the second cavity wall 1242. Among them, the through hole 1251 may be arranged on the first cavity wall 1241, and the through hole 1253 may be arranged on the third cavity wall 1243. Correspondingly, the supporting assembly 17 may include a bottom plate 171 and a first side plate 172 connected to the bottom plate 171, for example, in an L-shaped structure. Among them, one side main surface of the bottom plate 171 may be arranged opposite to the first cavity wall 1241, and support the electrode terminal 151; one side main surface of the first side plate 172 may be arranged opposite to the third cavity wall 1243, and support the microphone 152. In this way, after the electrode terminal 151 and the microphone 152 are assembled in place, the support assembly 17 is inserted into the accommodating cavity 124 along the above-mentioned insertion direction and after being inserted into place, the electrode terminal 151 and the microphone 152 can be supported respectively by the bottom plate 171 and the first side plate 172.

[0115] Furthermore, the orthographic projection of the microphone 152 on the first cavity wall 1241 can cover at least a portion of the electrode terminal 151 , for example, the microphone 152 covers a portion of the positive charging terminal 1511 , which is conducive to a more compact structure of each part.

[0116] In some embodiments, the size of at least part of the bottom plate 171 and the accommodating cavity 124 in the first reference direction RD1 perpendicular to the insertion direction and parallel to the main surface of one side of the bottom plate 171 can be set to gradually decrease along the insertion direction, that is, one of the front end and the rear end of the bottom plate 171 in the insertion direction or the part between the front end and the rear end can be set to keep the size in the first reference direction RD1 unchanged along the insertion direction. Among them, the size of the first side plate 172 and the accommodating cavity 124 in the second reference direction RD2 perpendicular to the insertion direction and parallel to the main surface of one side of the first side plate 172 can be set to remain unchanged along the insertion direction.

[0117] In some embodiments, the size of at least part of the first side plate 172 and the accommodating cavity 124 in the second reference direction RD2 perpendicular to the insertion direction and parallel to the main surface of one side of the first side plate 172 can be set to gradually decrease along the insertion direction, that is, one of the front end and the rear end of the first side plate 172 in the insertion direction or the part between the front end and the rear end can be set to keep the size in the second reference direction RD2 unchanged along the insertion direction. Among them, the size of the bottom plate 171 and the accommodating cavity 124 in the first reference direction RD1 perpendicular to the insertion direction and parallel to the main surface of one side of the bottom plate 171 can be set to remain unchanged along the insertion direction.

[0118] In some embodiments, the dimensions of at least a portion of the first side plate 172 and the accommodating cavity 124 in a second reference direction RD2 perpendicular to the above-mentioned insertion direction and parallel to the main surface of one side of the first side plate 172 can be set to gradually decrease along the above-mentioned insertion direction, and the dimensions of at least a portion of the first side plate 172 and the accommodating cavity 124 in a second reference direction RD2 perpendicular to the above-mentioned insertion direction and parallel to the main surface of one side of the first side plate 172 can be set to gradually decrease along the above-mentioned insertion direction.

[0119] It should be noted that: for the support assembly 17 , the size of the bottom plate 171 in the first reference direction RD1 can be simply regarded as the width of the bottom plate 171 , and the size of the first side plate 172 in the second reference direction RD2 can be simply regarded as the height of the first side plate 172 .

[0120] As an example, in combination Figures 16 to 18 The support assembly 17 may include a second side plate 173 connected to the bottom plate 171, the second side plate 173 and the first side plate 172 are arranged side by side and at intervals on the same side of the bottom plate 171, and the second side plate 173 abuts against the second cavity wall 1242 to provide the bottom plate 171 with a supporting force toward the electrode terminal 151, which is conducive to improving the supporting effect of the support assembly 17 on the electrode terminal 151. In the embodiment where the electrode terminal 151 includes a charging positive terminal 1511 and a charging negative terminal 1512 arranged at intervals along a direction perpendicular to the above-mentioned insertion direction, the second side plate 173 may be located between the charging positive terminal 1511 and the charging negative terminal 1512, so that each part of the electrode terminal 151 is subjected to uniform force, which is conducive to further improving the supporting effect of the support assembly 17 on the electrode terminal 151.

[0121] As an example, in combination Figures 16 to 18 , the cavity wall of the accommodating cavity 124 may include a fourth cavity wall 1244 connecting the first cavity wall 1241 and the second cavity wall 1242 and opposite to the third cavity wall 1243. The first cavity wall 1241 and the second cavity wall 1242 may be generally configured as a planar structure parallel to each other, and the third cavity wall 1243 and the fourth cavity wall 1244 may be generally configured as an arc surface structure expanding outward from each other, so as to maximize the volume of the accommodating cavity 124 when the volume of the transfer housing 122 is limited. Correspondingly, the support assembly 17 may include a third side plate 174 connected to the bottom plate 171, the first side plate 172 and the third side plate 174 are respectively located at the two side edges of the bottom plate 171 in a direction perpendicular to the above-mentioned insertion direction, and the second side plate 173 is located between the first side plate 172 and the third side plate 174. The third side plate 174 abuts against the fourth cavity wall 1244 to provide a supporting force for the first side plate 172 toward the microphone 152 , which is beneficial to improve the supporting effect of the supporting assembly 17 on the microphone 152 .

[0122] Further, relative to the bottom plate 171, the height of the second side plate 173 may be greater than the height of the first side plate 172 and the height of the third side plate 174, so that the second side plate 173 abuts against the second cavity wall 1242, and the third side plate 174 abuts against the fourth cavity wall 1244. Since the second side plate 173 and the third side plate 174 do not directly contact any of the electrode terminal 151 and the microphone 152, they can also be guided during the insertion of the support assembly 17 into the accommodating cavity 124. Accordingly, since the height of the second side plate 173 is relatively the highest, the support assembly 17 may include a reinforcing rib 175 connecting the second side plate 173 and the bottom plate 171. The reinforcing rib 175 may be provided on opposite sides of the second side plate 173 facing the first side plate 172 and the third side plate 174.

[0123] As an example, in combination Figures 15 to 17 and Fig. 9 The hook structure 12 may include an elastic wire 121, a transfer housing 122, a battery housing 123 and a wire 129. The two ends of the elastic wire 121 and the wire 129 may be connected to the transfer housing 122 and the battery housing 123, respectively, so that the wire 129 extends along the elastic wire 121 and is inserted into the transfer housing 122 and the battery housing 123. Of course, the wire 129 may also be inserted into the preset threading channel after the elastic wire 121 is connected to the transfer housing 122 and the battery housing 123. Among them, the battery 14 may be arranged in the battery housing 123, and may be connected to the flexible circuit board 16 through the wire 129, so that the battery 14 is also connected to the main control circuit board 13 through the flexible circuit board 16, which is conducive to simplifying the wiring structure of the earphone 10 and reducing the production cost. In other words, components such as the electrode terminal 151, the microphone 152 and the battery 14 in the hook structure 12 can be connected to the main control circuit board 13 through the flexible circuit board 16.

[0124] Furthermore, the flexible covering layer 128 may further cover at least the exposed parts of the elastic metal wire 121 and the wire 129 , and at least a part of the battery 123 , so that the wire 129 is exposed, which is beneficial to improving the appearance quality of the earphone 10 .

[0125] It should be noted that the adapter shell 122 can also be used as a part of the structure of the movement shell 111, for example, the adapter shell 122 is integrally formed with the movement inner shell 1111, and another example is that a part of the adapter shell 122 is integrally formed with the movement inner shell 1111 and the remaining part is integrally formed with the movement outer shell 1112. Among them, other parts of the hook-shaped structure 12 except the adapter shell 122, such as the end of the elastic metal wire 121 away from the battery shell 123, and another example is the battery shell 123, are fixedly connected to the movement module 11 with the adapter shell 122 at the adapter shell 122, such as plug-in fixation. Correspondingly, structural components such as the electrode terminal 151, the microphone 152 and the magnet 127 are also adjusted in position accordingly, which will not be repeated here.

[0126] Based on the above-mentioned related description, the present application provides a shell component, which may include a plastic shell, a metal functional pattern and a silicone coating, wherein the metal functional pattern is arranged on the outside of the plastic shell, and the silicone coating may be covered on the side of the metal functional pattern away from the plastic shell and on the plastic shell not covered by the metal functional pattern by means of integral injection molding, glue connection, etc. Thus, compared with the metal functional pattern being arranged on the inner side of the plastic shell away from the silicone coating, the metal functional pattern is arranged on the outer side of the plastic shell toward the silicone coating, so that it is further away from the interference of other electronic components in the shell component, or closer to the signal trigger source outside the shell component, thereby increasing the anti-interference and sensitivity of the metal functional pattern. Among them, the structure of the plastic shell may be the same or similar to that of the movement shell 111 or its movement shell 1112, and the structure of the silicone coating may be the same or similar to that of the flexible coating 1132, which will not be described in detail here.

[0127] In some embodiments, the metal functional pattern can be configured as an antenna pattern 1141 or a touch pattern 1142. The antenna pattern 1141 is configured on the outside of the plastic housing, which can increase the distance between the antenna pattern 1141 and other electronic components in the plastic housing, that is, increase the antenna clearance area, thereby increasing the anti-interference performance of the antenna pattern 1141; the touch pattern 1142 is configured on the outside of the plastic housing, which can shorten the distance between the touch pattern 1142 and an external signal trigger source (such as a user's finger), that is, shorten the touch distance, thereby increasing the sensitivity of the touch pattern 1142 to be triggered by the user.

[0128] In some embodiments, the metal functional pattern may include an antenna pattern 1141 and a touch pattern 1142. The antenna pattern 1141 may surround the touch pattern 1142 to fully utilize the space outside the plastic housing. The antenna pattern 1141 may be U-shaped, and the touch pattern 1142 may be square.

[0129] In some embodiments, the thickness of the silicone coating may be smaller than the thickness of the plastic housing, so that the silicone coating shields and protects the metal functional pattern while further increasing the anti-interference and sensitivity of the metal functional pattern and reducing the volume of the housing assembly.

[0130] As an example, the housing assembly can be used as a core housing for accommodating the speaker 112. The relative positional relationship between the plastic housing and the plastic coating can be the same or similar to that between the core housing 111 and the flexible coating 1132, and will not be described in detail.

[0131] Furthermore, in addition to being applied to the earphones 10, the shell assembly can also be applied to other electronic devices such as smart glasses. Among them, the electronic device may include a movement module provided with a speaker 112, and may also include a main control circuit board 13, and a speaker 112 and a battery 14 respectively coupled to the main control circuit board 13; the shell assembly can be used to accommodate at least one of the electronic components such as the speaker 112, the main control circuit board 13 and the battery 14, and can also be used to support the speaker 112 in the electronic device to be located in the corresponding wearing position. It is worth noting that: for electronic devices such as earphones and smart glasses based on the bone conduction principle, the speaker 112 can be adaptively adjusted to a bone conduction speaker. The basic structure of the bone conduction speaker is well known to those skilled in the art and will not be repeated here.

[0132] The present application provides a shell assembly, which may include a first shell, an electrode terminal 151, a magnet 127 and a flexible coating 128, wherein the electrode terminal 151 and the magnet 127 are exposed on the same side of the first shell, and the hardness of the flexible coating 128 is less than that of the first shell, and covers the first shell and the magnet 127, so that the magnet 127 is not exposed and the electrode terminal 151 is exposed. In this way, compared with the magnet 127 being arranged in the first shell, the technical solution makes the magnet 127 closer to the outside world to which the exposed end of the electrode terminal 151 faces, thereby shortening the distance between the magnet 127 and the magnetic attraction structure used to cooperate with the magnet 127 in the charging device such as the charging box or the distance between the Hall sensor used to cooperate with the magnet 127, which is conducive to improving the reliability of functions such as charging and detection. Therefore, the shell assembly can be applied to both power receiving devices such as headphones 10 and smart glasses, and charging devices such as charging boxes. In other words, the electronic device can be either a power receiving device or a charging device. Among them, for the convenience of description, the first shell can be a transfer shell 122.

[0133] In some embodiments, the first shell may be provided with a through hole 1251 and a blind hole 1252, the electrode terminal 151 may be at least partially disposed in the through hole 1251, and the magnet 127 may be at least partially disposed in the blind hole 1252 and exposed through the open end of the blind hole 1252. In this way, it is not only helpful to reduce the thickness of the first shell in the area where the magnet 127 is located, but also helpful to improve the appearance quality of the first shell in the area where the magnet 127 is located. Of course, the blind hole 1252 may also be provided as a through hole.

[0134] In some embodiments, a boss 126 may be provided on the outside of the first shell, the boss 126 is provided adjacent to the magnet 127 and protrudes from the first shell around the magnet 127, and the through hole 1251 further penetrates the boss 126, so that the plurality of electrode terminals 151 are exposed at the boss 126. In this way, the boss 126 makes the uneven part of the first shell due to a certain curvature become flat, so as to facilitate the arrangement of the electrode terminal 151. Among them, the boss 126 can be provided in a long strip shape, which is simple and reliable in structure.

[0135] In some embodiments, the housing assembly may include a flexible circuit board 16, and the electrode terminal 151 is connected to the flexible circuit board 16 to simplify the routing of the electrode terminal 151. The first housing may be formed with a receiving cavity 124, and at least part of the flexible circuit board 16 may be disposed in the receiving cavity 124. The through hole 1251 is connected to the receiving cavity 124, and the blind hole 1252 is not connected to the receiving cavity 124, so as to improve the waterproof and dustproof performance of the first housing.

[0136] In some embodiments, the housing assembly may include a second housing, an elastic wire 121, and a wire 129, and the two ends of the elastic wire 121 and the wire 129 may be connected to the first housing and the second housing, respectively, so that the wire 129 extends along the elastic wire 121 and is inserted into the first housing and the second housing. For ease of description, the second housing may be a battery housing 123. Further, a battery 14 is disposed in the second housing, and the battery 14 is connected to the flexible circuit board 16 through the wire 129, that is, the battery 14 and the electrode terminal 151 are both connected to the flexible circuit board 16 to simplify the wiring. Accordingly, the flexible coating 128 at least further covers the elastic wire 121 and the wire 129, so that the wire 129 is exposed.

[0137] In some embodiments, the housing assembly can be used for the earphone 10 and can include a third housing for accommodating the speaker 112 , the third housing being plugged and fixed to the first housing. For ease of description, the third housing can be the core housing 111 .

[0138] The present application provides a housing assembly, which may include a first housing, an electrode terminal 151, a microphone 152, and a support assembly 17. The first housing may be provided with a housing cavity 124, and through holes 1251 and 1253 respectively connected to the housing cavity 124, the through holes 1251 and 1253 are located on different side walls of the first housing, the electrode terminal 151 may be at least partially disposed in the through hole 1251, the microphone 152 may be disposed in the housing cavity 124, and pick up the sound outside the housing assembly through the through hole 1253. Further, the support assembly 17 may be disposed in the housing cavity 124, and may support and fix the electrode terminal 151 and the microphone 152 on the side walls corresponding to the through hole 1251 and the through hole 1253, respectively. In this way, it is not only beneficial to prevent the electrode terminal 151 and the microphone 152 from being separated from the first housing, but also beneficial to increase the waterproof and dustproof performance at the electrode terminal 151 and the microphone 152, and the structure is simple and reliable. For the convenience of description, the first shell may be the adapter shell 122 , the core shell 111 , or a shell structure in which the core shell 111 and the adapter shell 122 are integrally formed.

[0139] In some embodiments, the support assembly 17 may be independent of the first shell and inserted into the accommodating cavity 124 .

[0140] In some embodiments, the support assembly 17 may be an integrally formed structure.

[0141] In some embodiments, the housing assembly can be used for the earphone 10 and can include a third housing for accommodating the speaker 112 , and the third housing is plugged and fixed to the first housing. The first housing can be the adapter housing 122 , and the third housing can be the core housing 111 .

[0142] Furthermore, in addition to being applied to the earphones 10, the shell assembly can also be applied to other electronic devices such as smart glasses. Among them, the electronic device may include a main control circuit board 13, and a speaker 112 and a battery 14 respectively coupled to the main control circuit board 13; the shell assembly can be used to accommodate at least one of the electronic components such as the speaker 112, the main control circuit board 13 and the battery 14, and can also be used to support the speaker 112 in the electronic device to be located in the corresponding wearing position. It is worth noting that for electronic devices such as earphones and smart glasses based on the bone conduction principle, the speaker 112 can be adaptively adjusted to a bone conduction speaker. The basic structure of the bone conduction speaker is well known to technicians in this field and will not be repeated here.
