[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0029] Reference to “an embodiment” in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The skilled person explicitly and implicitly understands that the embodiments described in the present application can be combined with other embodiments.

[0030] The following is an exemplary description of the earphone embodiments.

[0031] In combination with Figure 1 The ear 100 of a user can include physiological parts such as an external auditory canal 101, a concha cavity 102, and an auricle 103. Although the external auditory canal 101 has a certain depth and extends to the tympanic membrane of the ear 100, for the convenience of description, the external auditory canal 101 specifically refers to the entrance (i.e., the ear hole) thereof away from the tympanic membrane in the present application without special indication. In addition, the concha cavity 102 has a certain volume and depth, and the concha cavity 102 is directly communicated with the external auditory canal 101, that is, the aforementioned ear hole can be simply regarded as being located at the bottom of the concha cavity 102.

[0032] The earphone 1 is an audio converter capable of receiving an electrical signal emitted from a media player or a receiver and converting the electrical signal into an audible sound wave for a user. In some embodiments, the earphone 1 can be an open earphone, such as an ear hook type earphone, a back hook type earphone, or an ear clip type earphone, etc.

[0033] As Figure 2 or Figure 3As shown, the earphone 1 can be an over-ear earphone, in some embodiments, at least part of the earphone 1 can be inserted into the concha cavity 102 of the user (wearer) in the wearing state, so as to improve the stability of wearing. In some embodiments, the sound generating part 20 of the earphone 1 can at least partially cover the pinna 103 of the user's ear, such as the position of the antihelix, the cymba concha, or the triangular fossa (not shown in the figure), but does not block or visually obstruct the external auditory canal 101 of the user's ear. In some embodiments, the sound generating part 20 of the earphone 1 can also be attached to or abut against the facial area in front of the user's ear, and the side of the sound generating part 20 used for sound generation faces the user's ear or the user's external auditory canal 101.

[0034] Further, different users can have individual differences, resulting in different sizes of the ear 100, such as different shapes and sizes. In order to facilitate description and reduce (or even eliminate) individual differences of different users, a simulator containing a head and its (left and right) ear 100 can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR, HEAD Acoustics, B&K 4128 series or B&K 5128 series, so as to present the scenario of most users wearing the earphone 1. 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 can be any one of HMS II.3, HMS II.3LN or HMS II.3LN HEC. Therefore, in this application, descriptions such as "the user wears the earphone 1", "the earphone 1 is in the wearing state" and "in the wearing state" can refer to the earphone 1 described in this application being worn on the ear 100 of the aforementioned simulator. Of course, because different users have individual differences, the earphone 1 worn by different users may have some differences from the earphone 1 worn on the ear 100 of the aforementioned simulator, but such differences should be tolerated.

[0035] It should be noted that in the field of medicine, anatomy, etc., three basic planes of the human body or human body simulator can be defined, namely, a sagittal plane, a coronal plane and a horizontal plane, and three basic axes, namely, a sagittal axis, a coronal axis and a vertical axis. The sagittal plane refers to a plane perpendicular to the ground made in the front-to-back direction of the body, which divides the human body or human body simulator into two parts; the coronal plane refers to a plane perpendicular to the ground made in the left-to-right direction of the body, which divides the human body or human body simulator into two parts; and the horizontal plane refers to a plane parallel to the ground made in the up-to-down direction of the body, which divides the human body or human body simulator into two parts. Correspondingly, the sagittal axis refers to an axis perpendicular to the coronal plane in the front-to-back direction of the body, the coronal axis refers to an axis perpendicular to the sagittal plane in the left-to-right direction of the body, and the vertical axis refers to an axis perpendicular to the horizontal plane in the up-to-down direction of the body. Further, the "front side of the ear" is a concept relative to the "rear 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 towards the head, both of which are for the ear 100 of the user or the simulator. As shown in Figure 1 .

[0036] As an example, in combination with Figure 2 and Figure 3 , the earphone 1 can include the ear hook 10 and the sound emitting part 20 connected to each other. In the wearing state, the ear hook 10 can be hung between the pinna 103 and the head of the user, that is, at least part of the ear hook 10 of the earphone 1 can be located at the rear side of the ear 100, so that the earphone 1 is hung on the ear 100, and the sound emitting part 20 can be located at the front side of the pinna 103. The sound emitting part 20 can be a sound playing device, which can be used to convert an electrical signal into an acoustic signal (also referred to as "sound wave" or "sound signal") and propagate to the ear 100 of the wearer.

[0037] In some embodiments, the ear hook 10 can be provided with a battery or a circuit board or the like, or the ear hook 10 can be provided with both a battery and a circuit board. Of course, the ear hook 10 can also not be provided with a battery and a circuit board or the like, and the battery and the circuit board or the like can be installed in the sound emitting part 20.

[0038] In some embodiments, as shown in Figures 1 to 5 , the sound emitting part 20 can include a movement core shell 210. In some embodiments, as shown in Figure 5As shown, the earphone 1 can further include a speaker assembly 30 disposed in the core casing 210. The speaker assembly 30 is a component that can convert an electrical signal into a corresponding acoustic signal to realize the sound playing function of the sound producing portion 20. As an example, the speaker assembly 30 can include a bone conduction speaker and an air conduction speaker, and in other embodiments, the speaker assembly 30 can also be provided as one of the air conduction speaker and the bone conduction speaker.

[0039] In some embodiments, as shown in Figures 2 to 5 As shown, the ear hook 10 can include an adapter casing 110 and a hook portion 120. The adapter casing 110 can be used to connect the core casing 210 and the hook portion 120. The hook portion 120 is in the shape of a hook for the user to hook on the ear 100 of the user when wearing the earphone 1.

[0040] As shown in Figures 5 to 7 The adapter casing 110 can be internally provided with a mounting groove 111. The mounting groove 111 can have a first groove wall 1111 and a second groove wall 1112 disposed opposite to each other and a mounting opening 1113 between the first groove wall 1111 and the second groove wall 1112. The adapter casing 110 can be provided with a sound collecting hole 112, and the sound emitting end 1121 of the sound collecting hole 112 is located on the first groove wall 1111.

[0041] The earphone 1 can further include a microphone 40 and a support plate 50, which are mounted between the first groove wall 1111 and the second groove wall 1112 through the mounting opening 1113. The support plate 50 is stacked with the microphone 40. The support plate 50 is located between the microphone 40 and the second groove wall 1112, and is used to press the microphone 40 against the first groove wall 1111. The microphone 40 collects the sound outside the earphone 1 through the sound collecting hole 112. The sound outside the earphone 1 can be, for example, the user's speaking sound, the sound of a whistle, the sound of a bell, the sound of surrounding people, or the sound of traffic guidance, etc.

[0042] Specifically, the support plate 50 and the microphone 40 are stacked along the arrangement interval direction of the first groove wall 1111 and the second groove wall 1112. The support plate 50 can press the microphone 40 against the first groove wall 1111, and the microphone 40 can be stabilized in the adapter casing 110 under the pressing action of the support plate 50 and the limiting action of the mounting groove 111. In this way, the microphone 40 can be pressed and fixed on the adapter casing 110 only by using a simple structure and components, so as to reduce the assembly difficulty of the microphone 40 in the earphone 1 and the assembly difficulty of the earphone 1.

[0043] Moreover, the microphone 40 can be directly corresponding to the sound hole 112 on the first slot wall 1111, and the microphone 40 can avoid the sound hole 112 communicating with the internal space of the earphone 1 as much as possible after being pressed on the first slot wall 1111, so that the air tightness between the microphone 40 and the sound hole 112 can be improved, and the sound collection effect of the microphone 40 can be improved.

[0044] In some embodiments, the material of the support plate 50 can be metal or hard plastic. In this way, the support plate 50 can have a certain anti-deformation ability, preventing the support plate 50 from being deformed or damaged when being installed and abutting against the microphone 40, thereby affecting the pressing effect of the microphone 40 and further affecting the air tightness of the earphone 1.

[0045] In some embodiments, as shown in Figure 5 The earphone 1 can include a flexible circuit board 60 and a master control circuit board 70. The master control circuit board 70 can be arranged in the core shell 210, and the installation opening 1113 can be towards the master control circuit board 70. Part of the flexible circuit board 60 can extend into the installation slot 111 through the installation opening 1113 and electrically connect the microphone 40 and the master control circuit board 70.

[0046] The master control circuit board 70 refers to the control core part inside the earphone 1, and the master control circuit board 70 can be a PCB (Printed Circuit Board) circuit board or a FPC (Flexible Printed Circuit board) circuit board. The master control circuit board 70 can be electrically connected to the microphone 40 and the loudspeaker assembly 30, respectively.

[0047] The flexible circuit board 60 (Flexible Printed Circuit, FPC for short) is a highly reliable and excellent flexible printed circuit board with high wiring density, light weight, thin thickness, and good bending properties. It is usually made of polyimide or polyester film as the substrate, also known as soft circuit board or flexible circuit board. Using the flexible circuit board 60 to connect the microphone 40 and the master control circuit board 70 can be more suitable for the complex internal space of the earphone 1. The flexible circuit board 60 is less likely to be damaged than ordinary wires, and the good bending property can avoid other elements in the core shell 210 and the adapter shell 110.

[0048] Specifically, one end of the flexible circuit board 60 is connected with the main control circuit board 70 in the core shell 210, and the other end extends into the mounting groove 111 through the mounting opening 1113 and is connected with the microphone 40. By arranging the mounting opening 1113 of the mounting groove 111 towards the main control circuit board 70, the one end of the flexible circuit board 60 can be connected with the main control circuit board 70, and the other end of the flexible circuit board 60 can extend into the mounting groove 111 for connection, so as to reduce the redundancy and folding of the flexible circuit board 60, and also to reduce the short circuit of the flexible circuit board 60.

[0049] In some embodiments, the support plate 50, the microphone 40, and the part of the flexible circuit board 60 are in interference fit with the mounting groove 111 in the direction of spacing along the first groove wall 1111 and the second groove wall 1112, so that the microphone 40 is tightly pressed on the first groove wall 1111. In other words, the distance between the first groove wall 1111 and the second groove wall 1112 is less than or equal to the sum of the thicknesses of the support plate 50, the microphone 40, and the part of the flexible circuit board 60 extending into the mounting groove 111. It should be noted that the thicknesses referred to here are the thicknesses of the components in the non-mounted state.

[0050] In this way, the components in the mounting groove 111 can be pressed more tightly, and the support plate 50, the microphone 40, and the part of the flexible circuit board 60 can be more stably clamped between the first groove wall 1111 and the second groove wall 1112, so as to improve the air tightness of the earphone 1 as a whole.

[0051] In some embodiments, as shown in Figure 7 and Figure 9 The dust screen assembly 1114 can be located between the first groove wall 1111 and the microphone 40. The dust screen assembly 1114 can be used to isolate impurities such as dust, particles, and water droplets in the air, so that the impurities such as dust, particles, and water droplets in the air are not easy to enter the adapter shell 110 and the core shell 210, thereby reducing the risk of corrosion or damage of the internal components such as the loudspeaker assembly 30 and the main control circuit board 70.

[0052] In some embodiments, the dust screen assembly 1114 can include steel mesh, gauze, isolation cotton sheet, and the like (not shown in the figure). Alternatively, in other embodiments, the dust screen assembly 1114 can include multiple layers of steel mesh or multiple layers of gauze.

[0053] The dustproof net assembly 1114 is also in interference fit with the support plate 50, the microphone 40 and the part of the flexible circuit board 60 in the mounting groove 111. In other words, the distance between the first groove wall 1111 and the second groove wall 1112 is less than or equal to the sum of the thicknesses of the dustproof net assembly 1114, the support plate 50, the microphone 40 and the part of the flexible circuit board 60 extending into the mounting groove 111. It should be noted that the thicknesses referred to here are the thicknesses of the components in the non-mounted state.

[0054] In some embodiments, the part of the flexible circuit board 60 can be located between the microphone 40 and the dustproof net assembly 1114. The sound outlet end 1121 of the sound collecting hole 112 communicates with the sound collection area 41 of the microphone 40, and the dustproof net assembly 1114, the part of the flexible circuit board 60 and the microphone 40 are all pressed by the support plate 50 on the first groove wall 1111, so that external sound and airflow are not easy to leak from the gap between the first groove wall 1111 and the dustproof net assembly 1114, the part of the flexible circuit board 60 and the microphone 40 during the process of entering the sound collection area 41 of the microphone 40 through the sound collecting hole 112, so as to avoid the airflow from entering the adapter housing 110 and the movement housing 210 as much as possible, thereby improving the overall air tightness of the earphone 1 and improving the sound collecting effect of the microphone 40.

[0055] In some embodiments, as shown in Figures 9 to 11 The adapter housing 110 can include a spacing plate 113 for forming the mounting groove 111, the second groove wall 1112 can be a side surface of the spacing plate 113 facing the mounting groove 111, and the spacing plate 113 can be provided with a groove 1131.

[0056] Since the microphone 40 and other components such as the support plate 50 provided in the mounting groove 111 are in interference fit with the mounting groove 111, the first groove wall 1111 and the second groove wall 1112 will both be slightly deformed. If the rigidity of the second groove wall 1112 is too large, it will be difficult to install. If the rigidity of the second groove wall 1112 is too small, the deformation of the second groove wall 1112 will be larger when the components are installed, and the pressing effect of the support plate 50 on the microphone 40 and other components will be poor. Therefore, by providing the groove 1131 on the spacing plate 113, the spacing plate 113 where the second groove wall 1112 is located can be more easily deformed slightly, so that the microphone 40 and other components such as the support plate 50 can be more easily installed into the mounting groove 111, thereby reducing the difficulty of installing the microphone 40 and facilitating the size installation and adjustment during the assembly of the earphone 1, thereby reducing the assembly difficulty of the earphone 1. At the same time, the spacing plate 113 can also have a certain rigidity to ensure the pressing effect of the support plate 50 on the microphone 40 and other components.

[0057] In some embodiments, as shown in Figure 11As shown, the length direction of the recess 1131 is arranged along the depth direction of the mounting groove 111, and the orientation of the slot opening 1132 of the recess 1131 can be the same as the orientation of the mounting opening 1113. As an example, the depth direction of the mounting groove 111 can be perpendicular to the interval direction between the first groove wall 1111 and the second groove wall 1112. Figure 11 The direction of the arrow C.

[0058] Specifically, the microphone 40 and the support plate 50 and other components are inserted into the mounting groove 111 through the mounting opening 1113 and further inserted into the mounting groove 111 along the depth direction of the mounting groove 111 to achieve interference fit with the mounting groove 111 and installation. Since the orientation of the slot opening 1132 of the recess 1131 is the same as the orientation of the mounting opening 1113, it indicates that the recess 1131 is in communication with the mounting opening 1113, and the length direction of the recess 1131 is arranged along the depth direction of the mounting groove 111, which can make the spacer plate 113 more easily deformed during the installation of the microphone 40 and the support plate 50, thereby making it easier for the microphone 40 and the support plate 50 to enter the mounting groove 111.

[0059] During the debugging and disassembly of the microphone 40, the microphone 40 and the support plate 50 are removed from the mounting groove 111 in the direction opposite to the depth direction of the mounting groove 111. Therefore, arranging the length direction of the recess 1131 along the depth direction of the mounting groove 111 can push the support plate 50 in the direction opposite to the depth direction of the mounting groove 111 to remove it during the debugging and disassembly of the microphone 40, thereby facilitating the removal of the microphone 40 and other components from the mounting groove 111 and reducing the difficulty of disassembling the earphone 1.

[0060] In some embodiments, after the microphone 40 and other components are assembled in the mounting groove 111, the mounting opening 1113 can be subjected to point gluing or drop gluing treatment, and the glue can seal the mounting opening 1113 to further fix the microphone 40 in the mounting groove 111. Moreover, the glue can further wrap the side of the spacer plate 113 opposite to the support plate 50, so that the glue is not easy to fall off from the mounting opening 1113 after solidification.

[0061] In some embodiments, as shown, Figures 2 to 6 The sound generating part 20 can have a connection end 220 for connecting the ear hook 10 and a free end 230 arranged opposite to the connection end 220. The sound generating part 20 has a length direction, a width direction and a thickness direction perpendicular to each other. At least part of the free end 230 can extend into the concha cavity 102 or abut against the pinna 103 of the user.

[0062] The length direction can be the interval direction of the connecting end 220 and the free end 230. The interval direction of the connecting end 220 and the free end 230 refers to the extension direction of the connecting line between the connecting end 220 and the free end 230. In some embodiments, the connecting end 220 and the free end 230 can be irregular or regular circular arcs, and the extension direction of the connecting line between the connecting end 220 and the free end 230 can refer to the direction defined by the straight line perpendicular to the parallel tangent plane of the two reference points on the connecting end 220 and the free end 230 with the farthest relative distance. The length direction can also be defined as the direction in which the core shell 210 approaches or moves away from the back of the head in the wearing state, that is, the direction defined between the side surface of the sound generating part 20 close to the back of the head and the side surface away from the back of the head in the wearing state. As an example, the length direction can be as shown by the arrow X in Figures 2 to 7 It should be noted that in the present specification, the length direction, width direction and thickness direction of the sound generating part 20 defined in the wearing state are all based on the sound generating part 20, and are independent of the three basic axes of the human body, and do not change due to the slight differences when worn on the ears of different users.

[0063] The width direction can be defined as the direction in which the core shell 210 approaches or moves away from the top of the head in the wearing state, that is, the direction defined between the side surface of the sound generating part 20 close to the top of the head and the side surface away from the top of the head in the wearing state. As an example, the width direction can be as shown by the arrow Y in Figures 3 to 7 .

[0064] The thickness direction can be the direction in which the sound generating part 20 faces or departs from the auricle 103 in the wearing state. As an example, the thickness direction can be as shown by the arrow Z in Figures 2 to 7 . The thickness direction Z can be substantially parallel to the vibration direction of the loudspeaker assembly 30 in the sound generating part 20, and substantially parallel refers to the spatial included angle between the two directions being less than 5°.

[0065] In some embodiments, as shown in Figure 6 , the depth direction of the mounting groove 111 can be inclined relative to the length direction X. The depth direction of the mounting groove 111 can be as shown by the arrow C in Figure 6 . In other words, the included angle between the depth direction C of the mounting groove 111 and the length direction X is not equal to 0°. By setting the depth direction C of the mounting groove 111 in this way, the accommodation space of the adapter shell 110 can be fully utilized, the space utilization rate is improved, and the size of the mounting groove 111 in the length direction X is reduced, so that the size of the earphone 1 in the length direction X can be reduced, and the mounting opening 1113 can be directed towards the main control circuit board 70.

[0066] In some embodiments, at least part of the hole section of the sound collecting hole 112 can be inclined relative to the vertical direction of the first groove wall 1111.

[0067] As exemplarily shown in FIG. 1, the extending direction of at least part of the hole section of the sound collecting hole 112 is shown as direction D of the arrow in FIG. 1, and the vertical direction of the first slot wall 1111 is shown as direction E of the arrow in FIG. 1. Figure 7 Figure 7 Figure 7

[0068] Since the sound outlet end 1121 of the sound collecting hole 112 is located on the first slot wall 1111 and communicates with the sound collecting area 41 of the microphone 40, and the sound outlet end 1121 of the sound collecting hole 112 penetrates the shell where the first slot wall 1111 is located, the at least part of the hole section of the sound collecting hole 112 is arranged to be inclined relative to the vertical direction E of the first slot wall 1111, so that the airflow is blocked and weakened by the inclined hole wall after entering the sound inlet end 1122 of the sound collecting hole 112, thereby reducing the case that the airflow directly impacts the microphone 40 after entering the sound inlet end 1122 of the sound collecting hole 112, to further reduce wind noise and improve the sound collecting effect of the microphone 40.

[0069] In some embodiments, the inclination angle of the extending direction of at least part of the hole section of the sound collecting hole 112 relative to the vertical direction of the first slot wall 1111 can be between 0° and 20°. As exemplarily, the inclination angle of the extending direction of at least part of the hole section of the sound collecting hole 112 relative to the vertical direction of the first slot wall 1111 can be 5°, 10°, 12°, 15° or 18°, etc.

[0070] As exemplarily shown in FIG. 1, the inclination angle of the extending direction D of at least part of the hole section of the sound collecting hole 112 relative to the vertical direction E of the first slot wall 1111 can be shown as angle a in FIG. 1, 5° < angle a < 20°. Figure 7 Figure 7

[0071] If the inclination angle of the extending direction D of at least part of the hole section of the sound collecting hole 112 relative to the vertical direction E of the first slot wall 1111 is equal to 0°, it means that the extending direction D of the sound collecting hole 112 is parallel to the vertical direction E of the first slot wall 1111, and when the airflow directly passes through the sound outlet end 1121 to impact the microphone 40 after entering the sound inlet end 1122 of the sound collecting hole 112, it will cause the microphone 40 to generate greater wind noise. If the inclination angle of the extending direction D of at least part of the hole section of the sound collecting hole 112 relative to the vertical direction E of the first slot wall 1111 is greater than 20°, it will occupy more space on the adapter shell 110, and also increase the processing difficulty of the sound collecting hole 112, and also cause excessive loss of effective sound information.

[0072] ​​​​​Therefore, the extension direction D of at least part of the hole section of the sound hole 112 is arranged to have an inclination angle of 0°-20° with respect to the vertical direction E of the first groove wall 1111. This not only allows the airflow to be blocked and weakened by the inclined hole wall after entering the sound inlet end 1122 of the sound hole 112, reduces the impact of the airflow on the microphone 40, thereby improving the wind noise resistance of the earphone 1, effectively improving the sound pickup effect of the microphone 40, but also reduces the space occupied by the sound hole 112 on the adapter shell 110, and facilitates the processing and formation of the sound hole 112 on the adapter shell 110.

[0073] In some embodiments, the extension direction of the entire hole section of the sound hole 112 can be arranged to have an inclination angle of 0°-20° with respect to the vertical direction of the first groove wall 1111. This facilitates the formation of the sound hole 112 on the adapter shell 110, and also reduces the weakening of the effective sound information by the sound hole 112, thereby ensuring the sound pickup effect and wind noise resistance effect of the microphone 40.

[0074] Of course, in other embodiments, the hole section of the sound hole 112 can have a shape that is partially inclined and partially curved. The shape of the hole section of the sound hole 112 is not listed one by one in this embodiment.

[0075] In some embodiments, the effective sound information can refer to target information, such as speech information or warning information, etc. In some embodiments, the effective sound information can refer to target frequency band sound information, such as sound information with a frequency band of 500Hz-1kHz, 1kHz-2kHz, or 200Hz-2kHz, etc.

[0076] In some embodiments, in the wearing state, the adapter shell 110 can be arranged adjacent to the upper ear root of the user. In the length direction X, the sound inlet end 1122 of the sound hole 112 can be closer to the free end 230 than the sound outlet end 1121 of the sound hole 112.

[0077] Since, in the direction of the vertical axis of the human body (i.e., in the relative direction from the top of the head to the bottom of the body), the free end 230 is closer to the user's mouth than the connecting end 220 in the wearing state of the earphone 1. Therefore, arranging the sound hole 112 in the length direction X such that the sound inlet end 1122 is closer to the free end 230 than the sound outlet end 1121 can make the sound inlet end 1122 closer to the user's mouth, thereby facilitating the microphone 40 to collect the user's sound through the sound hole 112, to enhance the sound pickup effect of the microphone 40.

[0078] In some embodiments, in the width direction Y, the sound inlet end 1122 of the sound hole 112 can be farther away from the upper ear base than the sound outlet end 1121 of the sound hole 112. Moreover, since the adapter housing 110 is arranged adjacent to the upper ear base of the user, arranging the sound hole 112 such that the sound inlet end 1122 is farther away from the upper ear base than the sound outlet end 1121 in the width direction Y can make the sound inlet end 1122 closer to the mouth of the user. In this way, the microphone 40 can be facilitated to collect the sound of the user through the sound hole 112, thereby enhancing the sound collection effect of the microphone 40.

[0079] In some embodiments, as shown in FIG. 1, the ear hook 10 can include a soft coating 80, which can wrap the adapter housing 110, and the sound hole 112 can extend into and through the soft coating 80. Figure 11

[0080] Specifically, the mounting groove 111 is arranged on the side of the adapter housing 110 away from the soft coating 80. The sound inlet end 1122 of the sound hole 112 can be located on the side of the soft coating 80 away from the adapter housing 110.

[0081] Wrapping the adapter housing 110 with the soft coating 80 can make the earphone 1 in the wearing state abut the adapter housing 110 to the ear 100 of the user through the soft coating 80, so that the human body can contact a softer part, thereby improving the user experience.

[0082] In some embodiments, the soft coating 80 can be made of flexible materials such as silicone or TPE (thermoplastic elastomer).

[0083] In summary, the mounting groove 111 is arranged on the adapter housing 110 of the earphone 1, the sound hole 112 is arranged on the second groove wall 1112 opposite the first groove wall 1111 in the mounting groove 111, the earphone 1 further includes the microphone 40 and the support plate 50, the microphone 40 and the support plate 50 are installed between the first groove wall 1111 and the second groove wall 1112 of the mounting groove 111, and the support plate 50 holds the microphone 40 on the second groove wall 1112 in the mounting groove 111. In this way, the microphone 40 can be installed and fixed on the adapter housing 110, and the microphone 40 can be directly corresponded to the sound hole 112 on the first groove wall 1111. By using only simple structures and elements, the microphone 40 can be held and fixed on the adapter housing 110, which can reduce the assembly difficulty of the microphone 40 in the earphone 1 and the assembly difficulty of the earphone 1. Moreover, after being held on the first groove wall 1111, the microphone 40 can avoid the sound hole 112 from being communicated with the internal space of the earphone 1 as much as possible, which can improve the air tightness between the microphone 40 and the sound hole 112, thereby improving the sound collection effect of the microphone 40.
