[0034] 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.

[0035] 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.

[0036] See also Figure 1 , Figure 11 is a schematic diagram of the front profile of the ear of the user or simulator in some embodiments. The ear 100 may include physiological parts such as the external auditory canal 101, the concha cavity 102, the cymba concha 103, the triangular fossa 104, the antihelix 105, the scaphoid 106, the helix 107 and the antitragus 108. Among them, the external auditory canal 101 has a certain depth and may extend to the tympanic membrane, but for the convenience of description, the external auditory canal 101 may specifically refer to the ear hole of the ear 100 unless otherwise specified in this application. In addition, physiological parts such as the concha cavity 102, the cymba concha 103, the triangular fossa 104 may also have a certain volume and depth. The concha cavity 102 may be directly connected to the external auditory canal 101, that is, it can be simply regarded as the ear hole being located at the bottom of the concha cavity 102.

[0037] It is understandable that there may be individual differences between different users, which may lead to different shapes, sizes and other dimensional differences of the ear 100. For the convenience of description, and to reduce (or even eliminate) the individual differences of different users, a simulator containing a head and its ear (generally a left ear and a right ear, and the left ear is taken as an example here) 100 can be made based on ANS: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR, HEADAcoustics, B&K 4128 series or B&K 5128 series, so as to present the scene of most users wearing headphones through the simulator. Taking GRAS KEMAR as an example, the simulator of the ear 100 can be any one of GRAS 45AC, GRAS 45BC, GRAS 45CC or GRAS 43AG. Taking HEAD Acoustics as an example, the simulator of the ear 100 may be any one of HMSII.3, HMS II.3LN or HMS II.3LN HEC.

[0038] It should be noted that in the fields of medicine and anatomy, three basic planes of the human body or human body simulator 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 or human body simulator 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 or human body simulator 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 or human body simulator 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” described in the present 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 ear 100 of the user or the simulator. When observing the ear 100 of the human body or the human body simulator along the direction of the coronal axis, it can be seen as follows: Figure 1 shown.

[0039] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 2 is a schematic diagram of the structure of headphones in some embodiments of the present application, Figure 3 yes Figure 2 The schematic diagram of the earphone in some embodiments is shown in a wearing state. Figure 4 yes Figure 2 The headset is shown in another perspective in some embodiments. Figure 5 yes Figure 2 The headphone 200 is a schematic diagram of a structure in another perspective in some embodiments. The headphone 200 may include a core module 10 and a hook structure 20 connected to the core module 10. The core module 10 is located at the front side of the ear 100 when worn. At least part of the hook structure 20 is located at the back side of the ear 100 when worn, so that the headphone 200 is hung on the ear 100 when worn.

[0040] In the present application, when describing the process or action of wearing the earphone 200, such as "wearing the earphone 200", "the earphone 200 is in a wearing state" and "in a wearing state", it can refer to the earphone 200 being worn on the ear 100. Of course, precisely because of individual differences between different users, there may be some differences between the earphone 200 worn by different users and the earphone 200 worn on the ear 100 of the simulator, but such differences should be tolerated.

[0041] In some embodiments, the core module 10 may have a connection end CE connected to the hook structure 20 and a free end FE not connected to the hook structure 20. The core module 10 may be configured not to block the external auditory canal 101 when worn, so that the earphone 200 is used as an "open earphone". It is understandable that due to individual differences between different users, when the earphone 200 is worn by different users, the core module 10 may partially block the external auditory canal 101, but the external auditory canal 101 is still not blocked.

[0042] Specifically, in order to improve the stability of the earphone 200 in the wearing state, the earphone 200 can adopt any one of the following methods or a combination thereof. First, at least a portion of the hook structure 20 is configured as a contoured structure that fits at least one of the rear side of the ear 100 and the head, so as to increase the contact area between the hook structure 20 and the ear 100 and / or the head, thereby increasing the resistance of the earphone 200 to fall off from the ear 100. Second, at least a portion of the hook structure 20 is configured as an elastic structure so that it has a certain amount of deformation in the wearing state, so as to increase the positive pressure of the hook structure 20 on the ear 100 and / or the head, thereby increasing the resistance of the earphone 200 to fall off from the ear 100. Third, at least a portion of the hook structure 20 is configured to abut against the head in the wearing state, so as to form a reaction force that presses the ear 100, so that the movement module 10 is pressed on the front side of the ear 100, thereby increasing the resistance of the earphone 200 to fall off from the ear 100. Fourthly, the movement module 10 and the hook structure 20 are configured to clamp the physiological parts such as the area where the antihelix 105 is located and the area where the cavum concha 102 is located from the front and back sides of the ear 100 when the earphone is worn, thereby increasing the resistance of the earphone 200 falling off the ear 100. Fifthly, the movement module 10 or the auxiliary structure connected thereto is configured to at least partially extend into the physiological parts such as the cavum concha 102, the cymba concha 103, the triangular fossa 104 and the scaphoid 106, thereby increasing the resistance of the earphone 200 falling off the ear 100.

[0043] Optionally, see Figure 3, in the wearing state, the free end FE of the movement module 10 can at least partially extend into the concha cavity 102. The movement module 10 and the hook structure 20 can be configured to clamp the ear 100 from the front and back sides of the ear 100 area corresponding to the concha cavity 102, thereby increasing the resistance of the earphone 200 to fall off the ear 100, thereby improving the stability of the earphone 200 in the wearing state. For example, the free end FE is pressed in the concha cavity 102 in the thickness direction X. For another example, the free end FE abuts against the concha cavity 102 in the length direction Y and the width direction Z.

[0044] It should be noted that: in the wearing state, the free end FE of the movement module 10 can not only extend into the concha cavity 102, but also be projected onto the antihelix 105, or onto the left and right sides of the head and located in front of the ear 100 on the sagittal axis. In other words, the hook-shaped structure 20 can support the movement module 10 to be worn at the concha cavity 102, the antihelix 105, the front of the ear 100 and other wearing positions.

[0045] Optionally, see Figure 3 , Figure 4 and Figure 5 , in the worn state, and observed along the direction of the coronal axis, the movement module 10 can be set to a circular, elliptical, rounded square, rounded rectangle, etc. shape. The movement module 10 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 10 approaches or moves away from the back of the head in the worn state, and the width direction Z can be defined as the direction in which the movement module 10 approaches or moves away from the top of the head in the worn state. Therefore, for ease of description, this embodiment takes the movement module 10 as a rounded rectangle as an example for exemplary description. Further, in some embodiments, the length of the movement module 10 in the length direction Y can be greater than the width of the movement module 10 in the width direction Z.

[0046] Optionally, the core module 10 may have an inner side IS facing the ear 100 and an outer side OS away from the ear 100 along the thickness direction X in the wearing state, and a connecting surface such as a lower side LS, an upper side US and a rear side RS connecting the inner side IS and the outer side OS. Among them, when the core module 10 is in the wearing state, the upper side US connects the inner side IS and the outer side OS, and away from the external auditory canal 101 along the width direction Z, the lower side LS connects the inner side IS and the outer side OS, and faces the external auditory canal 101, and the rear side RS connects the upper side US and the lower side LS, and may also connect the inner side IS and the outer side OS. The thickness direction X can also be defined as the direction in which the core module 10 approaches or moves away from the ear 100 in the wearing state. At least part of the connecting surface, such as the rear side OS, is located in the concha cavity 102 in the wearing state, and forms a first contact area with the front side of the ear 100 area. That is, the rear side RS may be located at one end of the length direction Y facing the back of the head in the wearing state, and at least partially located in the concha cavity 102. In some embodiments, the hook-shaped structure 20 forms a second contact area with the rear side of the ear 100 region in the wearing state. The second contact area and the first contact area at least partially overlap in the ear thickness direction of the ear 100 region. Furthermore, the movement module 10 and the hook-shaped structure 20 can jointly clamp the ear 100 from the front and back sides of the ear 100, and the clamping force formed is mainly manifested as compressive stress, which is beneficial to improve the stability and comfort of the earphone 200 in the wearing state. In some embodiments, when the movement module 10 is set to a circular, elliptical or other shape, the connecting surface may also refer to the arc-shaped side of the movement module 10.

[0047] Optionally, see Figure 6 and Figure 7 , Figure 6 yes Figure 2 A cross-sectional view of the middle earphone 200 along line VI-VI, Figure 7 yes Figure 2The cross-sectional view of the earphone 200 along line VII-VII. The movement module 10 may include a movement housing 11, a speaker 12, a sound cavity bracket 13, a main control circuit board 14, a microphone 15 and a sensor 16. Among them, the movement housing 11 may be connected to the hook structure 20. The movement housing 11 may have an installation space 201, which can be used to install the speaker 12, the sound cavity bracket 13, the main control circuit board 14, the microphone 15 and the sensor 16, etc. Of course, it can also be used to install other structures such as batteries, etc., which will not be repeated. The speaker 12, the sound cavity bracket 13, the main control circuit board 14, the microphone 15 and the sensor 16 can all be arranged in the movement housing 11, such as the installation space 201. The speaker 12 can be surrounded by the sound cavity bracket 13 to form an acoustic cavity 202. The main control circuit board 14 can be electrically connected to the speaker 12, the microphone 15 and the sensor 16 respectively. The main control circuit board 14 can be used to control the operation of the speaker 12 and / or the microphone 15. The main control circuit board 14 can be used to receive the electrical signal generated by the sensor 16 and generate corresponding control instructions based on the electrical signal to allow the earphone 200 to implement a preset function. The acoustic cavity 202 is located in the installation space 201 .

[0048] Optionally, see Figure 6 and Figure 7 The movement housing 11 may include a first housing 111 and a second housing 112 that are buckled together along the thickness direction X to form an installation space 201. The second housing 112 is closer to the ear 100 than the first housing 111 when worn. A parting surface 203 is provided between the first housing 111 and the second housing 112 to simplify the structure of the movement housing 11 and reduce processing costs. The second housing 112 is closer to the ear 100 than the first housing 111 when worn.

[0049] Preferably, see Figure 6 , Figure 7 and Figure 8 , Figure 8 yes Figure 6 Schematic diagram of the structure of the first shell 111 in some embodiments. In some embodiments, the first shell 111 can be a plastic part, and of course it can also be a shell structure made of other materials. The first shell 111 may include a bottom wall 1111 and a first side wall 1112 connected to the bottom wall 1111 and extending to a side close to the second shell 112. When wearing the earphone 200, the bottom wall 1111 can face the skin at the ear 100, and a part of the area can fit the skin.

[0050] Preferably, a sound outlet hole 1101 connected to the installation space 201 may be provided on the bottom wall 1111. The sound outlet hole 1101 may cooperate with the speaker 12 so that the sound waves generated by the speaker 12 are transmitted through the sound outlet hole 1101. Further, in some embodiments, the sound outlet hole 1101 may not be provided on the bottom wall 1111, but may be provided on the side of the first side wall 1112 corresponding to the lower side surface LS, and may also be provided at the corner between the first side wall 1112 and the bottom wall 1111. In some embodiments, the sound outlet hole 1101 may not be connected to the acoustic cavity 202. Further, in some embodiments, the bottom wall 1111 may be provided with a sound resistance net and / or a protective steel net at the sound outlet hole 1101.

[0051] The first side wall 1112 may extend from the edge of the bottom wall 1111 to the side close to the second housing 112, so as to be an integrally formed structural member with the bottom wall 1111 for easy processing, but it may not be an integrally formed structural member. In some embodiments, when viewed along the width direction Z and in the reference direction from the connection end CE to the free end FE, the portion of the first side wall 1112 close to the free end FE gradually approaches the bottom wall 1111 in the thickness direction X.

[0052] Preferably, in some embodiments, the first side wall 1112 may be used to set the sensor 16 , that is, the sensor 16 may be set on the first side wall 1112 .

[0053] It is worth noting that: when the movement module 10 is set to a rounded square, rounded rectangle or other shape, the sensor 16 may be at least partially located on the upper side surface US or the surface of the upper side surface US close to the rear side surface RS, or the sensor 16 may be at least partially located on the lower side surface LS or the surface of the upper side surface US close to the rear side surface RS, or the sensor 16 may be arranged opposite to the rear side surface RS in the length direction Y.

[0054] In addition, when the sensor 16 is set on the surface of the lower side surface LS close to the rear side surface RS or the surface of the upper side surface US close to the rear side surface RS, the free end FE extends into the concha cavity 102 when worn, which is more likely to trigger the sensor 16, thereby improving the experience of the earphone 200.

[0055] See also Figure 6 , Figure 7 and Fig. 9 , Fig. 9 yes Figure 6The second housing 112 in some embodiments may include a movement inner housing 113 that is buckled with the first housing 111, such as the first side wall 1112, along the thickness direction X to form an installation space 201, a flexible insert 114 disposed on the movement inner housing 113 and located outside the installation space 201, and a flexible coating 115 disposed on the movement inner housing 113 and located outside the installation space 201. The flexible insert 114 may be at least partially sandwiched between the movement inner housing 113 and the flexible coating 115.

[0056] The movement inner shell 113 can be a plastic part, and of course it can also be a shell structure made of other materials. The parting surface 203 between the movement inner shell 113 and the first shell 111, such as the first side wall 1112, is inclined toward the side where the first shell 111 is located in the direction close to the free end FE. In some scenarios, when observed along the width direction Z, the part of the movement inner shell 113 close to the free end FE is inclined toward the side close to the first shell 111, such as the first side wall 1112, and the part of the first shell 111, such as the first side wall 1112, close to the free end FE gradually moves away from the movement inner shell 113 in the thickness direction X, so that the first shell 111 and the movement inner shell 113 can match on the parting surface 203 to achieve buckling. In some scenarios, the movement inner shell 113 is inclined toward the side close to the first shell 111, such as the first side wall 1112, which can achieve concave, leaving space for setting the flexible insert 114, so as to reduce the influence of the flexible insert 114 on the appearance of the second shell 112 while reducing the installation space 201. In some scenarios, the movement inner shell 113 is inclined toward the side close to the first shell 111, such as the first side wall 1112, so that the movement shell 11 can support the flexible insert 114 as much as possible through the movement inner shell 113, thereby reducing the design difficulty of the flexible insert 114 and the design difficulty of the movement inner shell 113. In some scenarios, when observed along the width direction Z, the part of the movement inner shell 113 close to the free end FE is inclined toward the side close to the first shell 111, such as the first side wall 1112, so that the movement inner shell 113 can be provided with the flexible insert 114 in the area corresponding to the free end FE as much as possible, while the thickness of the movement inner shell 113 in the X direction is not increased as much as possible.

[0057] The movement inner shell 113 may include a top wall 1131 disposed opposite to the first shell 111 , such as the bottom wall 1111 , and a second side wall 1132 connected to the top wall 1131 and buckled with the first shell 111 , such as the first side wall 1112 .

[0058] The top wall 1131 may be provided with an antenna pattern and a touch control pattern and their respective metallized holes, etc. In some embodiments, the top wall 1131 may be provided with a sound pickup through hole that cooperates with the microphone 15 .

[0059] Observing along the width direction Z and in the reference direction from the connecting end CE to the free end FE, the portion of the second side wall 1132 close to the free end FE gradually moves away from the top wall 1131 in the thickness direction X, so that the split mold surface 203 is inclined toward the side of the first shell 111, such as the first side wall 1112, in the direction close to the free end FE, so as to cooperate with the first shell 111, such as the first side wall 1112, and further realize the concave inner shell 113 of the movement.

[0060] The second side wall 1132 may include a first sub-side wall segment 1133, a second sub-side wall segment 1134 connected to the first sub-side wall segment 1133, and a third sub-side wall segment 1135 connected to the second sub-side wall segment 1134 and engaged with the first housing 111, such as the first side wall 1112. The first sub-side wall segment 1133 is closer to the top wall 1131 than the second sub-side wall segment 1134 in the thickness direction X, the second sub-side wall segment 1134 is closer to the top wall 1131 than the third sub-side wall segment 1135 in the thickness direction X, and the third sub-side wall segment 1135 protrudes toward the outside of the movement housing 11 compared to the second sub-side wall segment 1134. The second sub-side wall segment 1134 protrudes toward the outside of the movement housing 11 compared to the first sub-side wall segment 1133. In short, the second side wall 1132 may be a stepped structure, so that the movement inner shell 113 is concave. In some embodiments, at least one of the first sub-sidewall segment 1133 and the second sub-sidewall segment 1134 may be omitted.

[0061] See also Fig.10 , Fig.10 yes Figure 6Schematic diagram of a portion of the structure of the earphone 200 in some embodiments. The first sub-side wall segment 1133 has a wall area 1136 as the inner wall of the second side wall 1132. The second sub-side wall segment 1134 has a wall area 1137 as the inner wall of the second side wall 1132. The third sub-side wall segment 1135 has a wall area 1138 as the inner wall of the second side wall 1132. In some embodiments, the wall area 1137 may be referred to as the first wall area, and the wall area 1138 may be referred to as the second wall area. In some embodiments, the wall area 1136 may be referred to as the first wall area, and the wall area 1137 may be referred to as the second wall area. In some embodiments, the wall area 1136 may be referred to as the first wall area, and the wall area 1138 may be referred to as the second wall area. In some embodiments, when the second sidewall 1132 can form any two of the wall regions 1136, 1137, and 1138, the second sidewall 1132 may not be limited to being composed of the first sub-sidewall segment 1133, the second sub-sidewall segment 1134, and the third sub-sidewall segment 1135, and may also be formed by other structural forms. In some embodiments, any two of the wall regions 1136, 1137, and 1138 formed by the second sidewall 1132 are not coplanar. In some embodiments, the curvature of the wall region 1136 is less than the curvature of the wall region 1137. In some embodiments, the curvature of the wall region 1136 is greater than the curvature of the wall region 1137. In some embodiments, the curvature of the wall region 1137 is less than the curvature of the wall region 1138. In some embodiments, the curvature of the wall region 1136 is less than the curvature of the wall region 1138.

[0062] In some embodiments, the first housing 111 and the movement inner housing 113 may be an integral structure.

[0063] The hardness of the flexible insert 114 is less than that of the first shell 111 and the movement inner shell 113, so as to improve the wearing comfort of the earphone 200. In some embodiments, the material of the flexible insert 114 can be silicone or rubber, etc., and can be formed on a preset area of ​​the movement inner shell 113 by injection molding, and can even be set on a preset area of ​​the first shell 111. In some embodiments, the flexible insert 114 can at least partially cover the area of ​​the first shell 111 and / or the movement inner shell 113 corresponding to the free end FE, so that the movement module 10 is at least partially against the concha cavity 102 through the flexible insert 114. In other words, the portion of the first shell 111 and / or the movement inner shell 113 that extends into the concha cavity 102 and contacts the concha cavity 102 can be covered by the flexible insert 114. Thus, when the movement module 10 is against the concha cavity 102, for example, when the movement module 10 and the hook structure 20 are configured to clamp the ear 100 from both the front and rear sides of the ear 100 region corresponding to the concha cavity 102 of the ear 100, the flexible insert 114 acts as a buffer between the movement housing 11 and the ear 100 to relieve the pressure of the earphone 200 on the ear 100, which is conducive to improving the comfort of the earphone 200 when worn. In some embodiments, since the flexible insert 114 at least partially covers the region of the first housing 111 and / or the movement inner housing 113 corresponding to the free end FE, and the parting surface 203 between the movement inner housing 113 and the first housing 111, for example, the first side wall 1112, is inclined toward the side where the first housing 111 is located in the direction close to the free end FE, the flexible insert 114 can be arranged on the movement inner housing 113 as much as possible, reducing the design difficulty of the movement inner housing 113. In addition, the flexible insert 114 cooperates with the concave of the movement inner shell 113 to more reasonably reduce the installation space 201, fully utilize the various positions and spaces of the movement shell 11, and enhance the appearance expression.

[0064] In some embodiments, the flexible insert 114 may continuously cover at least a portion of the first housing 111 and / or the movement inner shell 113 corresponding to the rear side RS, the upper side US, and the lower side LS.

[0065] In some embodiments, the flexible insert 114 cooperates with the concave inner shell 113 of the movement to control the area of ​​the outer surface of the flexible insert 114, so that the area will not be too small, which will not easily lead to the deterioration of the comfort of the movement module 10 in the wearing state and the deviation from the original intention of setting the flexible insert 114 due to the small area of ​​the flexible insert 114 abutting against the concha cavity 102. Therefore, the area will not be too large, which will not easily lead to the excessive size of the movement module 10.

[0066] In some embodiments, when viewed along the thickness direction X, the flexible insert 114 may be arranged in a U-shape.

[0067] In some embodiments, the portion of the flexible insert 114 corresponding to the lower side LS can be against the antitragus 108. The thickness of the portion of the flexible insert 114 corresponding to the rear side RS can be respectively smaller than the thickness of the portion of the flexible insert 114 corresponding to the upper side US and the lower side LS, so that good comfort can be obtained when the movement module 10 is against an uneven position in the concha cavity 102.

[0068] In some embodiments, the flexible inserts 114 are all disposed in the region of the movement inner shell 113 corresponding to the free end FE to simplify the structure of the movement module 10 and reduce the processing cost.

[0069] In some embodiments, the flexible insert 114 is at least partially disposed on the second side wall 1132. Of course, in addition to being disposed on the second side wall 1132, it may also be partially disposed on the top wall 1131.

[0070] In some embodiments, the outer surface of the flexible insert 114 can be continuously transitioned to the outer surface of the region of the movement inner shell 113 not covered by the flexible insert 114. This is beneficial to improving the appearance quality of the movement module 10 and avoiding the surface of the movement module 10 being bumpy.

[0071] In some embodiments, due to the provision of the second side wall 1132, the flexible insert 114 can be accumulated on the movement inner shell 113 during the injection molding process to avoid overflow, which is beneficial for the movement module 10 to better rest against the concha cavity 102 through the flexible insert 114, thereby improving the comfort of the earphone 200 when worn.

[0072] In some embodiments, the flexible insert 114 may be omitted.

[0073] The hardness of the flexible coating 115 is less than that of the first shell 111 and the core inner shell 113, so as to improve the wearing comfort of the earphone 200. In some embodiments, the flexible coating 115 may be silicone, rubber, etc., and may be formed on a preset area of ​​the first shell 111, the core inner shell 113 and / or the flexible insert 114 by injection molding, glue connection, etc. In some embodiments, the thickness of the flexible coating 115 is less than that of the core inner shell 113.

[0074] In some embodiments, the flexible covering 115 can be integrally covered on at least a portion of the outer surface of the flexible insert 114 and at least a portion of the outer surface of the first shell 111 and / or at least a portion of the movement inner shell 113 not covered by the flexible insert 114, which helps to enhance the consistency of the appearance of the movement module 10.

[0075] In some embodiments, the hardness of the flexible cover 115 is greater than that of the flexible insert 114 to allow the flexible insert 114 to be sufficiently soft. In addition, the flexible cover 115 can also improve the comfort of the earphone 200 when worn, and has a certain structural strength to protect the flexible insert 114.

[0076] In some embodiments, the flexible cover 115 may be omitted.

[0077] It can be understood that, due to the arrangement of the second side wall 1132 , the free end FE is arranged to be tapered in a direction away from the connection end CE.

[0078] See also Figure 6 and Figure 7 The speaker 12 can generate sound waves after being powered on, and can be transmitted through the sound outlet 1101 so as to be transmitted to the external auditory canal 101. The speaker 12 can be coupled to the main control circuit board 14 to allow operation under the control of the main control circuit board 14. In some embodiments, the speaker 12 can be adaptively adjusted to a bone conduction speaker based on electronic devices such as headphones and smart glasses based on the bone conduction principle. The basic structure of the bone conduction speaker is well known to those skilled in the art and will not be described in detail here.

[0079] The speaker 12 may face the first housing 111, such as the bottom wall 1111. The axial direction of the speaker 12 may be the thickness direction X, and of course, may be arranged to cross the thickness direction X.

[0080] The speaker 12 can be fixed on the first shell 111 , such as the bottom wall 1111 , or can be fixed on the first shell 111 with the cooperation of the sound cavity bracket 13 , and of course can also be fixed on the second shell 112 .

[0081] The speaker 12 can partially overlap with the second sub-side wall segment 1134 in the thickness direction X, so as to facilitate the arrangement of a sufficiently large speaker 12 in the first shell 111, thereby enhancing the sound volume produced by the earphone 200, that is, optimizing the arrangement and improving space utilization.

[0082] The space on the side of the speaker 12 away from the first housing 111, such as the bottom wall 1111, can be connected to the external environment through the acoustic hole, which is conducive to reducing the resistance of the diaphragm of the speaker 12 during vibration. In some embodiments, the space on the side of the speaker 12 away from the first housing 111, such as the bottom wall 1111, such as the acoustic cavity 202, can be connected to the external environment through the acoustic hole, which is conducive to reducing the resistance of the diaphragm of the speaker 12 during vibration. That is, the acoustic cavity 202 may not be connected to the sound outlet 1101.

[0083] See also Figure 6 , Figure 7 and Fig.11 , Fig.11 yes Figure 6 Schematic diagram of the partial structure of the middle sound cavity bracket 13 in some embodiments. The sound cavity bracket 13 and the speaker 12 can be surrounded to form an acoustic cavity 202, so that the acoustic cavity 202 is separated from other structures in the first shell 111 (such as the main control circuit board 14, etc.), which is conducive to improving the acoustic performance of the movement module 10. In addition, the acoustic cavity 202 can also be disconnected from the sound outlet 1101.

[0084] The sound cavity support 13 is connected in a cooperative manner, or even sealed, with the first housing 111. In some embodiments, the sound cavity support 13 is provided with an acoustic channel 1301 connecting the acoustic hole and the acoustic cavity 202, so as to facilitate the communication between the acoustic cavity 202 and the external environment.

[0085] The sound cavity bracket 13 may include an annular main body 131 and a docking portion 132 connected to the annular main body 131. The annular main body 131 is sleeved on the periphery of the speaker 12 to form an acoustic cavity 202, and the acoustic channel 1301 can pass through the docking portion 132 and the annular main body 131. The annular main body 131 can be connected with the first shell 111. Since the sound cavity bracket 13 is arranged in an annular shape, the speaker 12 is exposed toward one side of the main control circuit board 14, which is conducive to reducing the thickness of the movement module 10 in the thickness direction X.

[0086] In some embodiments, the docking portion 132 is located between the annular main body portion 131 and the first shell 111 and surrounds at least a portion of the acoustic hole. Accordingly, the docking portion 132 and the acoustic hole are arranged in a one-to-one correspondence.

[0087] In some embodiments, the sound cavity support 13 can be omitted.

[0088] See also Figure 6 , Figure 7 and Fig.12 , Fig.12 yes Figure 6 Schematic diagram of the partial structure of the earphone 200 in some embodiments. The main control circuit board 14 can be connected to the movement inner shell 113, for example, fixed on the hot melt column connected to the top wall 1131, and can partially overlap with the first side wall 1132, such as the first sub-side wall segment 1133, and even partially overlap with the second sub-side wall segment 1134 in the thickness direction X, so as to facilitate the installation of a sufficiently large speaker 12 in the movement shell 11, thereby enhancing the sound volume produced by the earphone 200, that is, optimizing the arrangement and improving the space utilization. In some embodiments, the main control circuit board 14 may not overlap with the first side wall 1132 in the thickness direction X.

[0089] In some embodiments, the thickness direction of the main control circuit board 14 may be the thickness direction X, and of course may also be arranged to cross the thickness direction X.

[0090] Since the main control circuit board 14 is arranged in the movement shell 11, for example, the main control circuit board 14 is connected to the movement inner shell 113, such as the top wall 1131, the main control circuit board 14 can be electrically connected to the antenna pattern and the touch pattern through elastic metal parts 41 such as pogo-PIN, metal springs, etc.

[0091] In some embodiments, the main control circuit board 14 is located on a side of the speaker 12 close to the inner shell 113 of the movement. In some embodiments, the main control circuit board 14 can be stacked with the speaker 12 in the thickness direction of the main control circuit board 14 or in the axial direction of the speaker 12. In some embodiments, along the axial direction of the speaker 12, the main control circuit board 14 can overlap with a portion of the speaker 12 or the sound cavity bracket 13 close to the connection end CE to optimize the arrangement and improve space utilization.

[0092] In some embodiments, a reinforcing lining 17 may be provided between the main control circuit board 14 and the speaker 12. Furthermore, the reinforcing lining 17 may also serve as a part of the movement module 10. The reinforcing lining 17 may facilitate spacing the main control circuit board 14 and the speaker 12, and reduce the influence of the speaker 12 on the main control circuit board 14. In some embodiments, the reinforcing lining 17 may also be fixedly connected to the main control circuit board 14 to play a role in fixing the main control circuit board 14. In some embodiments, the reinforcing lining 17 may also space the main control circuit board 14 and the sound cavity bracket 13, and reduce the influence of the sound cavity bracket 13 on the main control circuit board 14. In some embodiments, the reinforcing lining 17 may also be provided on the side of the sound cavity bracket 13 close to the main control circuit board 14. In some embodiments, the reinforcing lining 17 may be arranged in close contact with the main control circuit board 14 to improve the fixing effect and reduce the difficulty of assembly.

[0093] See also Figure 6 The microphone 15 can be directly welded on the main control circuit board 14 and can be located on a side of the main control circuit board 14 close to the inner shell 113 of the movement, such as the top wall 1131, so as to pick up voice and ambient sound through the sound pickup through hole. In some embodiments, the main control circuit board 14 can press the microphone 15 on the inner shell 113 of the movement, such as the top wall 1131. In some embodiments, the microphone 15 can be omitted.

[0094] Optionally, see Figure 6 , Fig.10 and Fig.12 The sensor 16 can be used to detect whether the user is wearing the headset 200 and generate a corresponding electrical signal, thereby allowing the control structure of the headset 200 (such as the main control circuit board 14) to implement a preset function, such as wearing detection. Preferably, in some embodiments, the sensor 16 may include a capacitive sensor, and the working principle and specific structure of the capacitive sensor are well known to those skilled in the art and will not be described in detail here.

[0095] Optionally, in some embodiments, a single earphone 200 is worn and a sensor 16 disposed on the single earphone 200 is triggered to generate an electrical signal, thereby allowing the control structure of the single earphone 200 (e.g., the main control circuit board 14) to generate a corresponding control instruction based on the electrical signal. Alternatively, a single earphone 200 is worn and multiple sensors 16 disposed on the single earphone 200 are triggered to generate multiple electrical signals, thereby allowing the control structure of the single earphone 200 (e.g., the main control circuit board 14) to perform differential operations on the multiple electrical signals and further generate corresponding control instructions.

[0096] Optionally, in some embodiments, wearing at least two earphones 200 triggers the sensors 16 disposed on the at least two earphones 200 respectively to generate multiple electrical signals, thereby allowing the control structure of the at least two earphones 200 (e.g., the main control circuit board 14) to perform differential operations on the multiple electrical signals and further generate corresponding control instructions.

[0097] Specifically, the control structure of the headset 200 (e.g., the main control circuit board 14) transmits the electrical signal to a mobile terminal such as a mobile phone, MP3, etc. that is connected to the headset 200, and the mobile terminal generates a corresponding control instruction based on the electrical signal. That is, the electrical signal allows the mobile terminal to implement a preset function, such as wearing detection.

[0098] Optionally, in some embodiments, the sensor 16 may be disposed in an area of ​​the skin of the movement housing 11 close to the ear 100 to allow the sensor 16 to be triggered when worn. Specifically, the sensor 16 may be fixed at a preset position by means of a colloid such as double-sided tape or glue, or may be formed at a preset position by laser direct molding technology, and the preset position may be a position in the movement housing 11.

[0099] Optionally, in some embodiments, the sensor 16 may include a capacitor plate 161 electrically connected to the main control circuit board 14 and a plate bracket 162 supporting the capacitor plate 161. Specifically, the sensor 16 may generate an electrical signal through the capacitor plate 161, that is, the sensor 16 may detect the wearing state through the capacitor plate 161, and the plate bracket 162 may enable the capacitor plate 161 to maintain a specific shape while supporting the capacitor plate 161, and may also enable the capacitor plate 161 to be as close as possible to the skin area of ​​the ear 100, thereby improving the detection accuracy of the wearing state.

[0100] Preferably, in some embodiments, the capacitor plate 161 can be integrally formed of a plate or sheet to facilitate processing. Thus, the thickness of the capacitor plate 161 can be ignored, and accordingly, the surface area on one side of the capacitor plate 161 in the thickness direction can be considered as the area of ​​the capacitor plate 161.

[0101] Optionally, in some embodiments, in the wearing state, the free end FE of the movement module 10 extends into the concha cavity 102, that is, the free end FE contacts or is close to the skin when worn, and then the capacitor plate 161 can be arranged in the movement housing 11 and close to one end of the free end FE, and cooperate with the skin area to detect the wearing state. Such an arrangement can make the capacitor plate 161 closer to the skin area, thereby improving the detection accuracy and reducing the possibility of false detection. Of course, in other embodiments, when conditions permit, the capacitor plate 161 can also be arranged at other positions in the movement housing 11 that can cooperate with the skin area. It can be understood that under the influence of the wearing method, the area where the movement module 10 cooperates with the skin area is also different, but the capacitor plate 161 should be arranged as close to the skin area as possible to improve the detection accuracy.

[0102] Preferably, in some embodiments, the capacitor plate 161 can be arranged between the speaker 12 and the free end FE, making full use of the gap between the speaker 12 and the free end FE to achieve the purpose of optimizing the arrangement and improving the space utilization. Moreover, the capacitor plate 161 can also be closer to the skin area and cooperate with the skin area. Further, in some embodiments, the capacitor plate 161 can at least partially overlap with the speaker 12 along the axial direction of the speaker 12. Further, in some embodiments, along the axial direction of the speaker 12, the capacitor plate 161 can overlap with a portion of the speaker 12 close to the free end FE to optimize the arrangement and improve the space utilization.

[0103] Optionally, in some embodiments, the capacitor plate 161 may extend through the gap between structures in the movement housing 11 toward one side of the movement inner shell 113 , such as the top wall 1131 , and may extend to a position electrically connected to the main control circuit board 14 , thereby realizing the detection function of the capacitor plate 161 .

[0104] Optionally, in some embodiments, the capacitor plate 161 may include a first main body 1611, a second main body 1612 spaced apart from the first main body 1611, a first connecting portion 1613 connecting the first main body 1611 and the second main body 1612 in a spaced region 1601 between the first main body 1611 and the second main body 1612, and a second connecting portion 1614 connecting the first main body 1611 and the main control circuit board 14. The capacitor plate 161 may be bent arbitrarily at least with the cooperation of the first connecting portion 1613 to better match the shape of the installation space 201 in the movement housing 11, so that the capacitor plate 161 may be arranged in a large area in the limited space of the installation space 201, thereby improving the accuracy of wearing state detection. Specifically, the cooperation of the first main body 1611, the second main body 1612, the first connecting part 1613 and the second connecting part 1614 enhances the adaptability of the capacitor plate 161 in a smaller space, so that it can be better arranged in the gap between the structures in the movement housing 11, so that the capacitor plate 161 can be opened as much as possible in the movement housing 11, and the wearing state detection accuracy can be improved by increasing the area. In addition, the capacitor plate 161 can be formed as a whole and presented, and can be extended into different gaps through the first main body 1611 and the second main body 1612 as extension branches, so as to open as much as possible to increase the area. It can be understood that when the area is increased, the wearing state detection accuracy can be improved, and then the capacitor plate 161 can be appropriately expanded while ensuring the wearing state detection accuracy. The distance that the capacitor plate 161 can be matched with the skin area. When the distance increases, the wearing method can be made more diversified and more suitable for different ears 100, so as to reduce the wearing status detection error caused by the differences between the ears 100, expand the use scenarios of the earphone 200, and improve the adaptability of the earphone 200.

[0105] Preferably, in some embodiments, the area of ​​the capacitor plate 161 can be set to 35-50 mm 2 , to ensure that the capacitor plate 161 has sufficient capacity for wearing detection. In addition, it is precisely the unique structural design of the capacitor plate 161 that enables the area of ​​the capacitor plate 161 to be designed larger.

[0106] Preferably, see Figure 6 and Fig.10, the first main body 1611 can be located on the outside of the main control circuit board 14, that is, on one side of the main control circuit board 14, to reduce the occupation of the space where the main control circuit board 14 is located, and can also reduce the electromagnetic influence of the main control circuit board 14 on the first main body 1611. Optionally, in some embodiments, the first main body 1611 can be located on one side of the main control circuit board 14 in a direction perpendicular to the thickness of the main control circuit board 14 to optimize the arrangement and improve space utilization. Optionally, in some embodiments, the first main body 1611 can be located on one side of the main control circuit board 14 close to the second side wall 1132, so as to optimize the layout of the capacitor plate 161 and improve space utilization, and the second side wall 1132 is closer to the free end FE, so that the first main body 1611 is closer to the skin area. Optionally, in some embodiments, the first main body 1611 can be disposed adjacent to the second side wall 1132 (e.g., the first sub-side wall segment 1133 or the second sub-side wall segment 1134), that is, the first main body 1611 can be disposed adjacent to the wall area 1136 or the wall area 1137, so that the structural stability of the capacitor plate 161 can be improved by selecting a wall area with a small degree of curvature. At the same time, the first main body 1611 can be opened as much as possible to increase the area of ​​cooperation with the skin area, improve the accuracy of wearing state detection, and appropriately expand the distance between the first main body 1611 and the skin area, so that the wearing method is more diversified, the use scenario of the headset 200 is expanded, and the adaptability of the headset 200 is improved. Optionally, in some embodiments, the first main body 1611 can be attached or electroplated on the second side wall 1132, such as the second sub-side wall segment 1134, so as to be closer to the skin area. That is, the first main body 1611 can be attached to the wall area 1136 or the wall area 1137. Optionally, in some embodiments, the first main body 1611 can be fitted and fixed to the second sub-sidewall segment 1134, such as the wall area 1137, to improve the fixing effect and reduce the difficulty of assembly. It can be understood that the fitting method can be performed in the form of bonding or electroplating.

[0107] Preferably, see Figure 6 and Fig.10In some embodiments, the second main body 1612 may be located outside the main control circuit board 14, that is, located on one side of the main control circuit board 14, to reduce the occupation of the space where the main control circuit board 14 is located, and also reduce the electromagnetic influence of the main control circuit board 14 on the second main body 1612. Optionally, in some embodiments, the second main body 1612 may be located on one side of the main control circuit board 14 in a direction perpendicular to the thickness of the main control circuit board 14 to optimize the arrangement and improve the space utilization. Optionally, in some embodiments, the second main body 1612 may be located on one side of the sound cavity bracket 13, such as the annular main body 131, close to the second side wall 1132, so as to optimize the layout of the capacitor plate 161 and improve the space utilization. The second side wall 1132 is closer to the free end FE, thereby making the second main body 1612 closer to the skin area. Optionally, in some embodiments, the second main body 1612 may be closer to the first shell 111, such as the bottom wall 1111, than the first main body 1611. Optionally, in some embodiments, the second main body portion 1612 can be arranged adjacent to the second side wall 1132 (for example, the second sub-side wall segment 1134 or the third sub-side wall segment 1135) to improve the detection sensitivity, that is, the second main body portion 1612 can be arranged adjacent to the wall area 1137 or the wall area 1138, and the second main body portion 1612 can be selected to cooperate with the wall area with a small degree of curvature to improve the structural stability of the capacitor plate 161. At the same time, the second main body portion 1612 can be opened as much as possible to increase the area of ​​cooperation with the skin area and improve the wearing status detection accuracy. The distance between the second main body portion 1612 and the skin area can also be appropriately expanded to make the wearing method more diversified, expand the use scenarios of the headset 200, and improve the adaptability of the headset 200. Optionally, in some embodiments, the second main body 1612 may be attached or electroplated on the second side wall 1132, such as the third sub-side wall section 1135, that is, the second main body 1612 may be attached to the wall area 1137 or the wall area 1138. Optionally, in some embodiments, the second main body 1612 may be attached and fixed to the third sub-side wall section 1135, such as the wall area 1138, to improve the fixing effect and reduce the difficulty of assembly. Optionally, in some embodiments, the second main body 1612 may be overlapped on the sound cavity support 13, such as the annular main body 131, and the sound cavity support 13 is used to achieve support. Optionally, in some embodiments, the second main body 1612 may be attached to the sound cavity support 13, such as the annular main body 131.
