DETAILED DESCRIPTION

[0051] Embodiments of the present disclosure are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and letters throughout the drawings denote the same or functionality function elements unless otherwise defined. The embodiments described below are examples of implementations of the present disclosure and are not intended to be limiting.

[0052] In the description of the present disclosure, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure.

[0053] Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0054] As described in the background, the earphone in the related art squeezes the tragus of the wearer, reducing the wearing comfort of the earphone. To solve the above technical problem, the present disclosure provides an earphone, which comprises a main body part, an extension part connected with the main body part, and a sound generating part connected with the extension part; in the wearing state, the end of the main body part away from the extension part extends downward along the back side of the ear part, the end of the extension part away from the main body part extends around the top of the helix of the ear part towards the concha of the ear part, and the sound generating part is located in the concha of the ear part; the extension part comprises an inner surface facing the concha, an outer surface facing the outside of the human body, an outer side surface facing the tragus, and an inner side surface facing the helix, and the inner surface of the extension part gradually inclines towards the direction of the ear hanging plane from the inner side surface side to the outer side surface side; wherein the ear hanging plane is a plane tangent to the back of the earphone or a human sagittal plane. In this way, by inclining the inner surface of the extension part relative to the direction of the ear hanging plane, there is a gap between the inner surface of the extension part and the tragus in the direction perpendicular to the ear hanging plane, which can reduce the squeezing and touching of the tragus and the helix foot of the wearer, and improve the wearing comfort of the earphone.

[0055] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present disclosure.

[0056] In order to clearly describe the structure of the earphone provided by the present disclosure, the structure of the ear and the wearing state, the front side, the back side, the upper side, the lower side of the ear part, the human sagittal plane, the coronal plane, the horizontal plane, the sagittal axis, the coronal axis, the vertical axis, and the definitions of X, Y, Z directions involved in the text will be described below.

[0057] Please refer to FIG. 1, the ear 200 of a user can include a helix 210, a suprameatal incisure 213, a cymba 220, a tragus 230, an antitragus 240, an antihelix 250, an upper antihelix crus 251, a lower antihelix crus 252, a triangular fossa 260, a helical crus 270, an ear canal opening 280, a concha 290, and the like. The cymba 220 can include a cymba concha 222 and a cymba cavity 221.

[0058] The "front side of the ear" described in the present disclosure is a concept opposite to the "rear side of the ear", the former refers to the side of the ear away from the head, the latter refers to the side of the ear towards the head, the "upper edge of the ear" refers to the outer edge of the helix side of the ear facing upwards, and the "lower edge of the ear" refers to the outer edge of the helix side of the ear facing downwards, all of which are for the ear of a user.

[0059] For the definition of the sagittal plane, the coronal plane, the horizontal plane, the sagittal axis, the coronal axis, and the vertical axis, it is well known in the fields of medicine, anatomy, etc. that the sagittal plane, the coronal plane, and the horizontal plane are three basic planes of the human body, and the sagittal axis, the coronal axis, and the vertical axis are three basic axes of the human body. The sagittal plane is a plane perpendicular to the ground made along the front-to-back direction of the body, which divides the human body into left and right parts; the coronal plane is a plane perpendicular to the ground made along the left-to-right direction of the body, which divides the human body into front and back parts; and the horizontal plane is a plane parallel to the ground made along the top-to-bottom direction of the body, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis is an axis perpendicular to the coronal plane along the front-to-back direction of the body, the coronal axis is an axis perpendicular to the sagittal plane along the left-to-right direction of the body, and the vertical axis is an axis perpendicular to the horizontal plane along the top-to-bottom direction of the body.

[0060] For the definition of the X, Y, and Z directions, refer to FIG. 2, a coordinate system is established with the center of the ear canal opening 280 as the origin. The direction pointing to the rear side of the ear and parallel to the sagittal axis is defined as the positive direction of the X axis; the direction pointing to the outer side of the ear and parallel to the coronal axis is defined as the positive direction of the Y axis (i.e. the direction outward along the paper in FIGS. 3-6); and the direction pointing to the top of the ear and parallel to the vertical axis is defined as the positive direction of the Z axis. It should be noted that the above direction definitions are for the convenience of description, and the X, Y, and Z directions can be defined arbitrarily as long as they meet the principles of the present technical solution, including but not limited to the axis symmetry and angular symmetry of the above-mentioned directions.

[0061] For the convenience of understanding and description of the shape of the earphone in the non-wearing state or the wearing state, the earphone can be projected on a specific plane, and the earphone can be described by parameters related to the projection shape of the earphone on the specific plane. In the wearing state, the earphone can be projected on the human sagittal plane to form a corresponding projection shape. In the non-wearing state, the earphone can be projected on the ear hanging plane to form a corresponding projection shape. The ear hanging plane can be determined as follows: the earphone is placed horizontally on a plane, and the back of the earphone is attached to the plane. The plane tangent to the back of the earphone can be used as the ear hanging plane. It is easy to understand that the plane tangent to the back of the earphone includes a plane tangent to most of the area of the back of the earphone. Please refer to FIG. 7, the ear hanging plane 300 is tangent to the back of the earphone, and there is a tangent point. In some embodiments, the ear hanging plane and the human sagittal plane can have a certain angle, such as between 10° and 30°. The earphone projected on the human sagittal plane and the ear hanging plane can form similar projection shapes. Of course, in some embodiments, the ear hanging plane and the human sagittal plane are parallel, and the earphone projected on the human sagittal plane and the ear hanging plane can form the same projection shape. Therefore, the human sagittal plane can also be regarded as the ear hanging plane.

[0062] Please refer to FIG. 4, FIG. 9 to FIG. 12, the earphone 100 includes a main body part 110, an extension part 120 and a sound generating part 130, and the main body part 110 and the extension part 120 are connected. The one end of the main body part 110 is a connection end, and the other end is a free end. The connection end of the main body part 110 is used to connect with the extension part 120. The main body part 110 is used to hang on the back of the ear, and can be balanced with the extension part 120 and the sound generating part 130, so that the earphone 100 can be better worn on the ear 200. In the wearing state, the free end of the main body part 110 can also abut against the back of the ear, such as the ear root, the earlobe, the head position behind the ear root, etc., thereby supporting the wearing of the earphone and facilitating the stable wearing of the earphone on the ear. In some embodiments, the free end of the main body part can be provided with a battery for powering the earphone, and can also be provided with an antenna, Bluetooth and other electronic elements for communication with other devices.

[0063] For the convenience of description, in some embodiments, in the wearing state, the ear root contact area of the earphone in contact with the ear root can be used as a boundary to divide the extension part 120 and the main body part 110. In summary, in the wearing state, the main body part 110 is mainly located on the back of the ear, and the extension part 120 is mainly located on the front side of the ear 200, so that the earphone 100 can be hung on the helix of the ear 200. In some embodiments, the part with the smallest cross-sectional area of the earphone can also be used as a boundary, in other words, the thinnest part of the earphone along the direction of the earphone can be used as a boundary to divide the main body part 110 and the extension part 120.

[0064] Please refer to FIG. 4 to FIG. 6, in the wearing state, the end of the main body 110 away from the extension 120 extends downward along the back of the ear, and the end of the extension 120 away from the main body 110 extends around the helix top of the ear 200 towards the concha of the ear. That is, the main body 110 and the extension 120 are located on the front side and the back side of the ear respectively, so as to hang the earphone 100 on the helix of the ear 200. Among them, the sound generating part 130 is located in the concha of the ear, so that the sound generating part 130 is closer to the ear canal opening, and the performance effect of the earphone sound quality is improved.

[0065] In some embodiments, the shape of the extension 120 can be a rectangular prism, a cylinder, a pyramid, and other regular and irregular bar-shaped three-dimensional structures. For the convenience of description, the structure of the extension 120 is defined as follows. Exemplarily, please refer to FIG. 4, FIG. 5 and FIG. 12, the extension 120 can include an inner surface 125 facing the concha 221, an outer surface 124 facing the outside of the human body, an outer side surface 126 facing the tragus, and an inner side surface 127 facing the helix; the direction from the outer surface 124 to the inner surface 125 can be the thickness direction of the extension 120, and the direction from the outer side surface 126 to the inner side surface 127 is the short axis direction of the extension 120, that is, the width direction of the extension; the direction from one end of the extension 120 connected with the main body 110 to the other end connected with the sound generating part 130 is the long axis direction of the extension 120, that is, the length direction of the extension 120.

[0066] Among them, the inner surface 125 of the extension 120 gradually inclines towards the direction of the ear hanging plane from the inner side surface 127 side to the outer side surface 126 side; wherein the ear hanging plane is a plane tangent to the back of the earphone or the human sagittal plane. In this way, in the direction perpendicular to the ear hanging plane, the inner surface 125 of the extension 120 has a spacing with the tragus, so as to reduce the extrusion and contact of the tragus and the helix foot of the wearer, and improve the wearing comfort of the earphone.

[0067] In some embodiments, the sound emitting part 130 is protruded from the inner surface 125 of the extending part 120, and the sound emitting part 130 is arranged in a stacked manner with the extending part 120 in the direction of the human body's coronal axis. In this way, in the wearing state, at least part of the inner surface 125 of the extending part 120 is higher than the tragus 211 in the Y-axis direction, and at least part of the sound emitting part 130 can be lower than the tragus in the Y-axis direction. On the one hand, the sound emitting part 130 can not press the tragus and the tragus incision 211, thereby improving the wearing comfort of the earphone. On the other hand, the sound emitting part 130 can extend into the concha cavity, and the sound emitting part 130 is also closer to the ear canal opening than the extending part 120, so that the sound of the earphone is more easily introduced into the ear canal opening, thereby improving the sound quality effect of the earphone. In addition, since the sound emitting part 130 contains a loudspeaker, the size of the loudspeaker has a great relationship with the sound quality of the earphone. Therefore, compared with the design that the sound emitting part 130 is usually arranged inside the extending part 120 or both are arranged at the same height, in the present embodiment, due to the stacked design of the sound emitting part 130 and the extending part 120 in the Y-axis direction, the minor axis of the extending part 120 can be arranged to be narrower, and the sound emitting part 130 can still have a large enough volume to accommodate a large loudspeaker. In this way, the narrower extending part can reduce the pressure on the tragus, the antihelix and other areas, and is also more beautiful. At the same time, the larger loudspeaker can still have good sound quality.

[0068] In some embodiments, at least part of the sound emitting part 130 is located inside the tragus of the ear, i.e., at least part of the sound emitting part is located on the side of the tragus facing the ear canal opening. In some embodiments, the sound emitting part 130 is completely located inside the tragus of the ear. In this way, the sound emitting part 130 is located in the concha cavity 221, but does not extend into the ear canal. Under the premise of ensuring that the sound emitting part 130 is as close as possible to the ear canal opening 280, the pressure on the ear canal can be reduced, the damage to the ear canal is reduced, and long-term wearing is suitable.

[0069] Further, the transition surface between the sound emitting part 130 and the outer side of the extending part 120 is a concave surface 140. Thus, in the wearing state, the concave surface 140 can provide a space for the tragus to avoid being pressed by the extending part.

[0070] In some embodiments, the end surface 134 of the sound emitting part 130 away from the extending part is arranged to be inclined with respect to the plane on which the inner surface of the extending part 120 is located. In this way, in the wearing state, the sound emitting part 130 can be located in the concha cavity, but can avoid pressing the antihelix and the tragus, thereby improving the wearing comfort of the earphone.

[0071] It needs to be understood that the end surface of the sound emitting part 130 away from the extension part can be inclined in a single dimension or in multiple dimensions relative to the inner surface of the extension part 120. Exemplarily, the end surface of the sound emitting part 130 is gradually inclined from the inner side surface 127 side of the extension part 120 to the outer side surface 126 side of the extension part 120 towards the ear hanging plane, in other words, the end surface of the sound emitting part 130 is gradually inclined from the inner side surface 127 side of the extension part 120 to the outer side surface 126 side of the extension part 120 towards the negative direction of the Y axis, and thus is arranged to be inclined, in the wearing state, the sound emitting part 130 can be better opposite to the ear canal opening, and the sound quality of the earphone is improved. In addition, the end surface of the sound emitting part 130 can also avoid the helix foot, so as to avoid extrusion on the helix foot, the helix and the tragus, thereby improving the wearing comfort.

[0072] Further, in some embodiments, the end surface of the sound emitting part 130 away from the extension part 120 can also be gradually inclined towards the direction of the ear hanging plane along the long axis of the extension part 120, in other words, in addition to the end surface of the sound emitting part 130 being gradually inclined from the inner side surface 127 side of the extension part 120 to the outer side surface 126 side of the extension part 120 towards the negative direction of the Y axis, the end surface of the sound emitting part 130 can also be gradually inclined towards the negative direction of the Y axis along the long axis direction of the extension part 120 at the same time, and thus is arranged to be inclined, in the wearing state, the end surface of the sound emitting part 130 can be closer to the ear canal, so that the sound emitting part 130 can be better opposite to the ear canal opening, and the sound quality of the earphone is improved.

[0073] In some embodiments, in the wearing state, the extension part 120 has a helix foot contact area with the helix of the ear, and the highest point of the projection of the helix foot contact area on the ear hanging plane along the human body vertical axis direction is defined as the ear hanging top point 212 of the earphone.

[0074] In some embodiments, the vertical shortest distance L11 between the projection of the outer peripheral surface of the sound emitting part 130 on the ear hanging plane and the ear hanging top point 212 of the earphone is 18mm-22mm, and the vertical maximum distance L12 between the projection of the outer peripheral surface of the sound emitting part 130 on the ear hanging plane and the ear hanging top point 212 of the earphone is 37mm-44mm.

[0075] In the present disclosure, the above distance can be measured by the following method: making a first tangent line 131 and a second tangent line 132 on the projection of the outer circumferential surface of the sound generating part 130 on the ear hook plane, wherein the first tangent line 131 and the second tangent line 132 are parallel to each other and parallel to the horizontal plane, the first tangent line 131 passes through the highest point of the projection of the outer circumferential surface on the ear hook plane along the vertical axis direction of the user, and the second tangent line 132 passes through the lowest point of the projection of the outer circumferential surface on the ear hook plane along the vertical axis direction of the user. Taking the orientation shown in FIG. 15 as an example, the first tangent line 131 and the second tangent line 132 are both located below the ear hook apex 212, and the first tangent line 131 is located above the second tangent line 132. If L11 is too small, the sound generating part 130 will be too close to the ear region such as the suprathmoid incisure, the crura of the helix, the tragus, etc., so that one end of the sound generating part 130 will press against the above-mentioned ear region; if L12 is too large, the other end of the sound generating part 130 will be too close to the ear region such as the antihelix, the concha cavity, etc., so that the sound generating part 130 will press against the antihelix and the concha cavity; by setting L11 and L12, in the wearing state, the sound generating part 130 can be well located in the concha cavity, without contacting the ear region such as the crura of the helix, the antihelix, and the concha cavity, etc., so as to improve the wearing comfort of the earphone.

[0076] In some embodiments, the width L13 of the projection of the extension part 120 corresponding to the ear root contact area on the human body horizontal plane is less than or equal to 3 mm. This is to avoid the extension part 120 pressing against the ear root, thereby improving the wearing comfort of the earphone.

[0077] Please refer to FIG. 12, the extension part 120 includes a first arc segment 121, a second arc segment 122, and a long strip segment 123 for connecting the first arc segment 121 and the second arc segment 122. The first arc segment 121 is connected to the main body part 110 at one end away from the long strip segment 123, and the second arc segment 122 is bent towards the concha cavity 221 of the ear 200 at one end away from the long strip segment 123, and is connected to the sound generating part 130. The first arc segment 121 surrounds the antihelix of the ear, so that the long strip segment 123 connected thereto can be hung on the front side of the ear. It should be noted that the portion between the main body part 110 and the long strip segment 123 is defined as the first arc segment 121, or the portion between the main body part 110 and the long strip segment 123 can be further divided, for example, the portion between the main body part 110 and the long strip segment 123 can include the connection segment 129 and the first arc segment 121.

[0078] In some embodiments, in the wearing state, the connecting section 129 can represent the section where the earphone contacts the ear base; the first arc section 121 can represent the arc section where the earphone crosses the helix but does not exceed the triangular fossa of the ear; and the long strip section 123 and the second arc section 122 can be bounded by the vertex of the extension 120 relative to the plane of the ear hook, the arc section at the end of the extension 120 being the second arc section, and the extension between the first arc section 121 and the second arc section 122 being the long strip section 123. The vertex 128 is the highest point of the extension 120 relative to the plane of the ear hook. It should be understood that the shape of the first arc section 121 and the connecting section 129 needs to cooperate with the top of the helix, and the shape of the second arc section 122 needs to cooperate with the concha, i.e., the connecting section 129, the first arc section 121, and the second arc section 122 are not regular shapes, and therefore, the inner surface 125 of the extension 120 is inclined relative to the plane of the ear hook, and it can be understood that the inner surface of the long strip section 123 is inclined relative to the plane of the ear hook. This makes the area of the extension 120 towards the human side avoid the tragus 230, thereby avoiding the extension 120 pressing the tragus 230 in the direction perpendicular to the plane of the ear hook 300, reducing or even avoiding the pain caused by pressing the tragus 230, and improving the wearing comfort of the earphone.

[0079] In the present embodiment, the inclined angle a1 can refer to the long strip section 123, i.e., the plane in which the inner surface of the long strip section 123 represents the plane in which the inner surface 125 of the extension. Exemplarily, the inclined angle a1 between the end surface of the sound generating portion 130 away from the extension 120 and the inner surface of the long strip section 123 is 22°-28°.

[0080] That is, the inclined angle a1 between the end surface of the sound generating portion 130 away from the extension 120 and the plane in which the inner surface 125 of the extension is 22°-28°

[0081] The second arc section 122 includes at least one of the following features:

[0082] The second arc section 122 gradually bends from the inner side 127 of the extension 120 to the outer side 126 of the extension 120, so that the second arc section 122 bends towards the concha, showing a visual effect of gradually narrowing in the short axis direction of the extension, thereby making the second arc section 122 avoid the helix and the concha in the wearing state, preventing the ear from being pressed, and improving the wearing comfort. In addition, the connecting surface of the second arc section 122 and the long strip section 123 and the end surface of the second arc section 122 away from the long strip section 123 can be arranged in an up-down staggered manner in the direction perpendicular to the plane of the ear hook, which can effectively improve the space utilization, facilitate the reduction of the volume of the extension 120, and make the earphone 100 develop in the direction of miniaturization. On the other hand, the sound generating portion 130 can be closer to the ear canal opening 280, improving the sound quality of the earphone.

[0083] The outer surface of the second arc segment 122 is curved from the connecting surface with the long strip segment 123 to the end of the second arc segment 122 towards the inner surface 125 of the extension 120; that is, in the Y-axis direction, from the long strip segment 123 to the second arc segment 122, the outer surface of the extension 120 is curved towards the negative direction of the Y-axis, presenting a visual effect of the end of the second arc segment 122 being thinner, so that in the wearing state, the outer surface of the second arc segment 122 can avoid the antitragus and prevent extrusion of the antitragus.

[0084] The transition surface between the outer surface of the second arc segment 122 and the sound generating part 130 is a concave surface 140. Thus, in the wearing state, the concave surface can exactly provide a space for the antitragus to avoid, avoiding extrusion of the antitragus by the extension.

[0085] For further clarity of description, the inclined relationship between the extension 120 and the ear hook plane, and the inclined relationship between the end surface of the sound generating part 130 away from the extension 120 and the inner surface of the extension 120, are defined by taking the long strip segment 123 with a regular shape as an example.

[0086] Exemplarily, the inclined angle a2 between the inner surface of the long strip segment 123 and the ear hook plane; and / or the inclined angle a1 between the end surface 134 of the sound generating part 130 away from the extension and the inner surface of the long strip segment 123. It should be understood that the selection and determination of the inclined angle a1 and the inclined angle a2 in the embodiment can be designed according to the desired position of the sound generating part 130 relative to the ear canal opening; for example, please refer to FIG. 8, the component adjacent to the ear canal opening is the simulation body of the sound generating part 130. According to the three-dimensional coordinate axis origin as the reference, we can define the following angle range to indicate the ideal angle of the sound generating part 130 pointing to the center point of the ear canal opening:

[0087] In the coordinate system with the positive direction of the X-axis as 0° and the positive direction of the Y-axis as 90°, the angle of the horn pointing to the center point of the ear canal opening is between +10° and +80°. In the coordinate system with the positive direction of the X-axis as 0° and the positive direction of the Z-axis as 90°, the angle of the horn pointing to the center point of the ear canal opening is between -70° and +70°. In the coordinate system with the positive direction of the Y-axis as 0° and the positive direction of the Z-axis as 90°, the angle of the horn pointing to the center point of the ear canal opening is between -70° and +70°. The overlapping part of the above three angle ranges forms a spatial angle range, which is the best angle range indicating the sound generating part 130 pointing to the center point of the ear canal opening.

[0088] The inclined angle a2 between the inner surface of the long strip segment 123 and the ear hook plane is 8°-9°, for example, the inclined angle a2 is 8°, 8.2°, 8.4°, 8.5°, 8.8°, or 9°. By adjusting the size of the inclined angle a2, the end of the extension 120 away from the main body 110 can be made as close as possible to the concha cavity 221 in the direction perpendicular to the ear hook plane 300, thereby facilitating the sound generating part 130 of the earphone to be closer to the ear canal opening (see FIG. 6), and improving the sound quality of the earphone.

[0089] The inclined angle a1 between the end surface of the sound generating part 130 away from the extension 120 and the inner surface of the long strip segment 123 is 22°-28°. The inclined angle a1 is 22°, 22.5°, 23°, 23.5°, 24°, 24.5°, 25°, 25.5°, 26°, 26.5°, 27°, 27.5°, or 28°, and preferably the inclined angle a1 is 27.5°. By limiting the inclined angle a1, the sound generating part 130 can have an ideal angle pointing to the center of the ear canal opening when the sound generating part 130 is arranged opposite to the ear canal opening, thereby making the sound quality of the earphone clearer and the audio experience more outstanding, and also avoiding the extension 120 and the sound generating part 130 from pressing the antihelix crus and the tragus, thereby improving the wearing comfort of the earphone.

[0090] The earphone provided in the embodiment is reasonably designed by the inclined angle a1 and the inclined angle a2, which complement each other to ensure that the sound generating part 130 can have a gap with the tragus and the antihelix crus in the direction perpendicular to the ear hook plane, thereby avoiding the extension 120 from pressing the tragus and the antihelix crus, and at the same time, avoiding the sound generating part 130 from pressing the antihelix and the tragus.

[0091] In some embodiments, referring to FIG. 12 and FIG. 19, the distance L3 between the projection of the outer edge point 133 of the sound generating part on the ear hook plane and the projection of the outer side surface of the long strip segment 123 on the ear hook plane is 3mm-5mm. For example, L3 is 3mm, 4mm, or 5mm. The outer edge point 133 of the sound generating part is the point farthest from the outer side surface of the long strip segment 123 on the outer circumferential surface of the sound generating part 130 away from the antihelix 250. By limiting L3 and cooperating with other features of the extension 120, the sound generating part 130 can be prevented from pressing the concha cavity 221, and the sound generating part 130 can be further miniaturized.

[0092] In some embodiments, referring to FIG. 27, the width L5 of the first arc segment 121 in the sagittal axis direction is less than or equal to 15 mm, and / or the height L4 of the first arc segment 121 in the vertical axis direction is less than or equal to 12 mm. By limiting the width L5 of the first arc segment 121 in the sagittal axis direction and / or the height L4 of the first arc segment 121 in the vertical axis direction, the first arc segment 121 of the extension 120 can be miniaturized, and thus the extension 120 and the earphone 100 can be miniaturized.

[0093] Referring to FIGS. 27 and 28, the cross-sectional area S1 of the first arc segment 121 gradually decreases along the direction of the long strip segment 123 pointing to the main body 110. The maximum value of the cross-sectional area S1 of the first arc segment 121 is less than 75 mm2.

[0094] The embodiments can miniaturize the first arc segment 121 of the extension 120 by limiting the cross-sectional area S1 of the first arc segment 121, the width L5 of the first arc segment 121 in the sagittal axis direction, and the height L4 of the first arc segment 121 in the vertical axis direction, and thus the extension 120 and the earphone 100 can be miniaturized. In addition, the first arc segment 121 can avoid pressing the crus of the helix, and the wearing comfort of the earphone can be improved.

[0095] Referring to FIGS. 29 and 30, the width L6 of the long strip segment 123 in the short axis direction of the long strip segment 123 is greater than 11 mm and less than 15 mm. For example, the width L6 of the long strip segment 123 is 12 mm, 13 mm, 14 mm, or 15 mm. The distance L7 between the outer surface of the long strip segment 123 and the inner surface of the long strip segment 123 is less than or equal to 8 mm, that is, the thickness of the long strip segment 123 is less than or equal to 8 mm. By limiting the width and thickness of the long strip segment 123, the long strip segment 123 of the extension 120 can be miniaturized, and thus the extension 120 and the earphone 100 can be miniaturized.

[0096] Referring to FIG. 20, the distance L1 between the end surface 134 of the sound generating portion 130 facing away from the extension 120 and the vertex of the extension 120 in the coronal axis direction of the human body is in the range of 12 mm to 16 mm. For example, the distance L1 between the end surface of the sound generating portion 130 facing away from the extension 120 and the vertex of the extension 120 is 12 mm, 13 mm, 14 mm, 15 mm, or 16 mm. The vertex of the extension 120 is the highest point of the extension 120 relative to the ear hook plane. By limiting the distance L1 between the end surface of the sound generating portion 130 facing away from the extension 120 and the vertex of the extension 120, the sound generating portion 130 can be prevented from pressing the concha cavity 221, and the sound generating portion 130 can be closer to the ear canal opening, and the sound quality of the earphone can be improved.

[0097] Please refer to FIG. 13 and FIG. 23, the distance L8 between the vertex of the extension 120 relative to the ear hook plane and the ear hook plane is in the range of 13mm-16mm; if the distance L8 between the vertex of the extension 120 relative to the ear hook plane and the ear hook plane is greater than 16mm, it will cause extrusion to the tragus; if the distance L8 between the vertex of the extension 120 relative to the ear hook plane and the ear hook plane is less than 13mm, it will cause extrusion to the concha. Therefore, the embodiment limits L8, under the premise of ensuring that the sound generating part 130 is located in the concha, it also avoids extrusion of the extension 120 to the tragus and the concha, and improves the wearing comfort of the earphone.

[0098] In some embodiments, please refer to FIG. 21 and FIG. 22, the axial thickness L2 of the sound generating part 130 is less than 12mm; and / or, the maximum outer diameter d1 of the sound generating part 130 is in the range of 10mm-15mm, for example, the maximum outer diameter d1 of the sound generating part 130 is 10mm. By setting this way, the size of the sound generating part 130 can be reduced, which not only can avoid extrusion of the sound generating part 130 to the tragus and the antihelix, but also can be beneficial to the miniaturization of the earphone. Among them, the thickness of the sound generating part 130 can be measured by the following method: taking the geometric center of the end surface 134 of the sound generating part away from the extension as the vertical line, which can be considered as the central axis of the sound generating part, and the thickness of the sound generating part 130 on the central axis is the thickness L2 of the sound generating part; and the maximum outer diameter of the sound generating part 130 can be measured as follows: on the end surface of the sound generating part away from the extension, the distance between the two outermost points is measured as the maximum outer diameter d1 of the sound generating part.

[0099] At the same time, the distance L9 between the end surface of the sound generating part 130 away from the extension 120 and the ear hook plane on the coronal axis is in the range of -4mm-2mm. For example, the value of L9 is -4mm, -3mm, -2mm, -1mm, 0, 0.5mm, 1mm, 1.5mm or 2mm. Among them, the negative number means that the end surface of the sound generating part away from the extension is at least partially lower than the ear hook plane. By setting this way, the sound generating part 130 can avoid the concha, and further avoid extrusion of the sound generating part 130 to the concha.

[0100] Please refer to FIG. 25, along the long axis of the extension 120, the length L10 of the long strip segment 123 ranges from 28mm to 32mm. For example, the length L10 of the long strip segment 123 can be 28mm, 29mm, 30mm, 31mm or 32mm. If the length L10 of the long strip segment 123 is less than 28mm, the sound production part 130 cannot be ensured to be in the concha cavity, which reduces the sound quality of the earphone 100 and can press the antitragus. If the length L10 of the long strip segment 123 is greater than 32mm, the long strip segment 123 will be too long, which can cause the sound production part 130 to press the antihelix. Therefore, the length of the long strip segment 123 is limited in this embodiment, which can ensure that the sound production part 130 is in the concha cavity and improve the sound quality of the earphone 100, and can also avoid pressing the antitragus and the antihelix.

[0101] It should be noted that the length range of the long strip segment 123 provided in this embodiment can also cooperate with the value range of the distance L8 between the vertex of the extension 120 relative to the tragus plane and the tragus plane to ensure that the sound production part 130 can better approach the ear canal opening. Please refer to FIG. 30, along the long axis of the extension 120, the length L15 of the second arc segment 122 ranges from 13mm to 17mm. Alternatively, along the extension direction of the long strip segment 123, the length L15 of the second arc segment 122 ranges from 13mm to 17mm. For example, the length L15 of the second arc segment 122 along the extension direction of the long strip segment 123 can be 13mm, 14mm, 15mm, 16mm or 17mm. By limiting the length of the second arc segment 122, the length of the extension 120 in the extension direction of the long strip segment 123 can be more accurately controlled, so that the sound production part 130 is located in the concha cavity, which is conducive to the sound production part 130 better approaching the ear canal opening and improving the sound quality effect of the earphone.

[0102] In some embodiments, please refer to FIG. 31, the distance L14 between the end surface 134 of the sound production part away from the extension and the inner surface of the extension 120 in the direction of the coronal axis of the human body is greater than 1.5mm. This minimum distance L14 and the aforementioned inclination angle α1 complement each other, which can better ensure that the sound production part 130 is closer to the ear canal opening and improve the sound quality effect of the earphone 100.

[0103] The earphone provided by the embodiment of the present disclosure comprises a main body part 110, an extension part 120 connected with the main body part 110, and a sound production part 130 connected with the extension part 120; in the wearing state, the end of the main body part 110 away from the extension part 120 extends downwards along the back side of the ear, the end of the extension part 120 away from the main body part 110 extends around the top of the helix of the ear towards the concha of the ear, and at least part of the sound production part 130 is inside the tragus; wherein the extension part 120 comprises a first arc segment 121, a long strip segment 123 and a second arc segment 122 connected in sequence, one end of the first arc segment 121 away from the long strip segment 123 is connected with the main body part 110, one end of the second arc segment 122 away from the long strip segment 123 is bent towards the concha of the ear, and the sound production part 130 is convexly arranged on the inner surface of the second arc segment 122, that is, the sound production part 130 is arranged on the side of the second arc segment 122 facing the concha, and the sound production part 130 and the second arc segment 122 are arranged in a stack in the direction of the human body coronal axis. In other words, the sound production part 130 and the extension part 120 are arranged in a stack in the Y-axis direction, and the projection of the sound production part 130 on the ear hanging plane at least partially overlaps the projection of the second arc segment 122 on the ear hanging plane, which can effectively improve the space utilization, facilitate the reduction of the volume of the extension part 120, and make the earphone 100 develop in the direction of miniaturization. On the other hand, the sound production part 130 can be closer to the ear canal opening, and the sound quality of the earphone is improved.

[0104] In the embodiment, the sound production part 130 is convexly arranged on the inner surface of the second arc segment 122, and the sound production part 130 and the extension part 120 are arranged in a stack in the direction of the human body coronal axis. In this way, the sound production part 130 and the extension part 120 are arranged in a stack in the Y-axis direction, at least part of the inner surface 125 of the extension part 120 is higher than the suprameatal incisure 211 in the Y-axis direction in the wearing state, and at least part of the sound production part 130 can be lower than the tragus in the Y-axis direction; therefore, on the one hand, the sound production part 130 can not press the tragus and the suprameatal incisure 211, and the wearing comfort of the earphone is improved. In addition, due to the stack design of the sound production part 130 and the extension part 120 in the Y-axis direction, the minor axis of the extension part 120 can be arranged to be narrower, and the sound production part 130 can still have a large enough volume to accommodate a larger speaker, so that the narrower extension part can reduce the pressure on the tragus, the helix and other areas, and is more beautiful, and the wearing comfort of the earphone is improved.

[0105] In some embodiments, the earphone further comprises a battery and a main board, the battery is configured to provide power output for the main board and the sound generating part 130. The battery can be arranged on the main body part 110 or the extension part 120. In an example, the battery is arranged on the end of the main body part 110 away from the extension part 120, and the main board is arranged on the extension part 120, so that the battery is arranged opposite to the main board and the sound generating part 130, which can better balance the weight of the earphone 100 and provide a more comfortable wearing experience. In another example, the battery and the main board are arranged separately on the extension part 120. In order to ensure the normal operation of the main board, a wire needs to be arranged between the battery and the main board, and the wire can be routed in the extension part 120. By arranging the battery and the main board separately on the extension part 120, it is not necessary to route the wire in the main body part 110, which can shorten the length of the wire connecting the battery and the main board, and make the processing process of the earphone 100 simpler and reduce the production cost of the earphone 100.

[0106] Please continue to refer to FIG. 14, the cross-sectional area of the main body part 110 gradually increases in the direction away from the extension part 120, that is, the cross-sectional area of the main body part 110 gradually increases in the direction from top to bottom in FIG. 14. Compared with the technical solution that the cross-sectional area of the main body part 110 is equal everywhere, the volume and weight of the main body part 110 can be reduced, and the wearing comfort of the earphone is improved. Among them, the cross-sectional area of the end of the main body part 110 away from the extension part 120 is the largest, which can better balance the weight of the earphone and improve the wearing comfort of the earphone on the premise of reducing the volume of the main body part 110.

[0107] Please refer to FIG. 4, the earphone 100 further comprises a first sound outlet hole 150, the first sound outlet hole 150 is arranged on the sound generating part 130. In some embodiments, the first sound outlet hole 150 is arranged on the end face of the sound generating part 130, specifically, on the end face of the sound generating part 130 away from the extension part 120, the first sound outlet hole 150 is located on the side of the sound generating part 130 close to the ear canal opening, that is, on the side close to the outer side of the extension part 120; in some embodiments, the first sound outlet hole 150 can also be arranged on the wall surface where the sound generating part 130 is connected with the second arc segment 122, that is, the first sound outlet hole 150 is arranged on the transition surface between the outer side of the second arc segment 122 and the sound generating part 130. In this way, in the wearing state, the first sound outlet hole 150 can better point to the ear canal opening, and the center distance between the first sound outlet hole 150 and the ear canal opening is also smaller, for example, the center distance between the first sound outlet hole and the ear canal opening is not greater than 6mm; in this embodiment, the design of the first sound outlet hole 150 can ensure that the sound emitted by the sound generating part 130 can be directly transmitted to the ear canal opening, and the performance effect of sound quality and volume is improved.

[0108] In some embodiments, referring to FIG. 4 and FIG. 5, the earphone 100 further comprises a second sound outlet hole 160, which is arranged on the inner side of the extension 120, and specifically, the second sound outlet hole 160 can be arranged on the inner side of the second arc segment 122. In this way, in the wearing state, the second sound outlet hole 160 is directly opposite the concha cavity below the antihelix, and the sound emitted by the second sound outlet hole is still easy to enter the concha cavity and then enter the ear canal, thereby improving the sound quality effect of the earphone, and the position of the second sound outlet hole 160 can be well hidden, thereby improving the aesthetics of the earphone. In some embodiments, the second sound outlet hole 160 can also function as a pressure relief hole.

[0109] Referring to FIG. 2 to FIG. 6, and FIG. 9 and FIG. 33, the shell 600 is provided with a first sound pickup hole 1210 and a first microphone cavity 1220, and the first sound pickup hole 1210 communicates with the first microphone cavity 1220. Among them, the first microphone cavity 1220 is located inside the shell 600, the first sound pickup hole 1210 is opened on the surface of the shell 600, and one end of the first sound pickup hole 1210 communicates with one end of the first microphone cavity 1220, so that the outside of the shell 600 can communicate with the first microphone cavity 1220 through the first sound pickup hole 1210. The first microphone 310 is arranged in the first microphone cavity 1220 of the shell 600, so that the first microphone 310 can be located in the shell 600 as a whole, so that the shell 600 can protect the first microphone 310. The sound waves outside the shell 600 can enter the first microphone cavity 1220 through the first sound pickup hole 1210, so that the sound waves are received by the first microphone 310 and converted into an electrical signal. Specifically, when the user uses the earphone of the present disclosure to make a call or record, the sound emitted by the user can enter the first microphone cavity 1220 through the first sound pickup hole 1210, so that the sound emitted by the user is received by the first microphone 310 and converted into an electrical signal.

[0110] It should be noted that the volume of the first microphone cavity 1220 of the shell 600 can be set to be greater than the volume of the first microphone 310, so that when the first microphone 310 is arranged in the first microphone cavity 1220, the first microphone 310 has a certain gap with the inner wall of the first microphone cavity 1220, so that the sound can be better received by the first microphone 310.

[0111] When the earphone of the present disclosure is worn on the ear, the first sound pickup hole 1210 of the shell 600 is opposite to at least part of the area of the side of the tragus 230 of the ear facing the cymba concha 221, so that part of the tragus 230 can shield the first sound pickup hole 1210 of the shell 600. Specifically, when the user wears the earphone of the present disclosure against the wind, the first sound pickup hole 1210 is located on the side of the tragus 230 away from the windward side, and the tragus 230 can block at least part of the wind noise, so that the energy of the wind noise waves entering the first sound pickup hole 1210 into the first microphone cavity 1220 is relatively low. Correspondingly, the energy of the wind noise waves entering the first microphone cavity 1220 and received by the first microphone 310 is also relatively low, thereby reducing the wind noise of the earphone of the present disclosure during call recording and improving the signal-to-noise ratio of the earphone.

[0112] In some embodiments, referring to FIG. 9, the first sound pickup hole 1210 on the shell 600 in the present disclosure can be arranged on one of the outer wall of the sound generating part 130, the outer wall of the extension part 120, and the transition surface of the sound generating part 130 and the extension part 120. In this way, when the first sound pickup hole 1210 is shielded by the side of the tragus 230 facing the cymba concha 221, the first sound pickup hole 1210 is relatively closer to the user's mouth 500, so that the sound emitted by the user is more easily entered into the first sound pickup hole 1210 and received by the first microphone 310.

[0113] Specifically, when the first sound pickup hole 1210 is arranged on the outer wall of the sound generating part 130, the first sound pickup hole 1210 can be located on the outer wall of the sound generating part 130 facing the tragus 230, thereby making the first sound pickup hole 1210 not be shielded by the inner wall of the cymba concha 221, so that the sound emitted by the user is more easily entered into the first sound pickup hole 1210 and received by the first microphone 310, thereby making the earphone of the present disclosure have good sound pickup effect.

[0114] When the first sound pickup hole 1210 is arranged on the outer wall of the extension part 120, the first sound pickup hole 1210 can be located on the outer wall of the extension part 120 facing the tragus 230, i.e., on the inner side surface 127 of the extension part 120. The first sound pickup hole 1210 is not arranged on the inner surface 125 of the extension part 120, so that the first sound pickup hole 1210 is not shielded by the inner surface of the cymba concha 221, so that the sound emitted by the user is more easily entered into the first sound pickup hole 1210 and received by the first microphone 310, thereby making the earphone of the present disclosure have good sound pickup effect. The first sound pickup hole 1210 is not arranged on the outer surface 124 of the extension part 120, which can avoid the first sound pickup hole 1210 being completely exposed to the outside of the ear 200, thereby avoiding dust and impurities entering the first sound pickup hole 1210 to some extent, and avoiding wind noise from the direction of the coronal axis of the human body from entering the first sound pickup hole 1210 to some extent, so that the earphone of the present disclosure has good sound pickup effect.

[0115] It should be understood that the transition surface between the extension part 120 and the sound production part 130 is an arc surface structure connecting the extension part 120 shell and the sound production part 130 shell. By providing the transition surface, the connection between the extension part 120 shell and the sound production part 130 shell is smoother, and the wearing comfort of the earphone of the present disclosure is improved.

[0116] When the first sound pickup hole 1210 is arranged on the transition surface, the first sound pickup hole 1210 is located on the region of the transition surface facing the tragus 230. Thus, the distance between the first sound pickup hole 1210 and the user's mouth 500 is smaller, so that the first microphone 310 can better receive the sound emitted by the user.

[0117] Referring to FIG. 9, in the embodiment of the present disclosure, the first microphone cavity 1220 can be arranged in the extension part 120. Thus, the relatively large outer surface area and the relatively large internal space of the extension part 120 can be fully utilized, and the structure arrangement of the earphone of the present disclosure is more reasonable.

[0118] In some embodiments, referring to FIG. 35, when the earphone of the present disclosure is worn on the user's ear 200, the height of the first sound pickup hole 1210 is lower than the height of the tragus 230 in the direction of the coronal axis of the user's body. Thus, the first sound pickup hole 1210 can be completely blocked by the user's tragus 230. When the user faces the wind, the tragus 230 can sufficiently block the wind noise wave, so as to further reduce the wind dry sound wave energy entering the first microphone cavity 1220, thereby further improving the signal-to-noise ratio of the earphone of the present disclosure.

[0119] In some embodiments, the first sound pickup hole 1210 of the present disclosure has a distance from a preset plane, wherein the preset plane is parallel to the sagittal plane of the ear, and the plane passing through the highest point of the tragus 230 in the direction of the coronal axis. The preset plane is shown by the S plane marked in FIG. 35, and the distance between the first sound pickup hole 1210 and the preset plane is represented by L16 in FIG. 35. The first sound pickup hole 1210 has a distance L16 from the preset plane, so that the tragus 230 can completely block the first sound pickup hole 1210. When the user faces the wind, the tragus 230 can sufficiently block the wind noise wave, so as to further reduce the wind dry sound wave energy entering the first microphone cavity 1220, thereby further improving the signal-to-noise ratio of the earphone of the present disclosure.

[0120] In some embodiments, referring to FIG. 35, the first sound pickup hole 1210 of the present disclosure is spaced apart from the preset plane by a distance greater than 1.5 mm. It should be understood that when the wind noise wave propagates towards the tragus 230 of the user, the wind noise wave can also fluctuate in a direction deviating from the sagittal plane when part of the wind noise wave passes the end of the tragus 230. By spacing the first sound pickup hole 1210 apart from the preset plane by a distance greater than 1.5 mm, the first sound pickup hole 1210 can be spaced apart from the preset plane by a larger distance, so that even when part of the wind noise wave fluctuates, this part of the wind noise wave can be sufficiently prevented from entering the first sound pickup hole 1210, thereby further playing the role of the tragus 230 in blocking wind noise, and making the call recording quality of the earphone of the present disclosure higher.

[0121] In some embodiments, referring to FIGS. 6, 33 and 34, the first microphone cavity 1220 of the present disclosure is located on the side of the first sound pickup hole 1210 away from the tragus 230. In this way, the first microphone cavity 1220 is spaced apart from the tragus 230 by a larger distance than the first sound pickup hole 1210 is spaced apart from the tragus 230, and the first microphone cavity 1220 can make full use of the space on the side of the housing 600 away from the tragus 230, so that the internal structure layout of the earphone is more reasonable.

[0122] In some embodiments, referring to FIG. 33, the housing 600 of the present disclosure further has a sound guide channel 1240, and the first sound pickup hole 1210 communicates with the first microphone cavity 1220 through the sound guide channel 1240. When the user wears the earphone of the present disclosure in a moving state or in a windy environment, the wind noise outside the housing 600 generated by the wind force passes through the first sound pickup hole 1210 and then enters the first microphone cavity 1220 through the sound guide channel 1240, which can lengthen the path of the wind noise wave to the first microphone cavity 1220. The energy of the wind noise wave itself can be gradually consumed during the process of the wind noise wave passing through the sound guide channel 1240, so that the wind noise energy entering the first microphone cavity 1220 is relatively low, and the wind noise received by the first microphone 310 is relatively small, so that the earphone of the present disclosure generates less wind noise during call recording, thereby making the earphone have a better call recording effect.

[0123] In addition, when the wind noise wave passes through the sound guide channel 1240 of the housing 600, the wind noise wave also contacts the inner wall of the sound guide channel 1240, so that the wind noise wave is further attenuated during the process of the wind noise wave impacting and contacting the inner wall of the sound guide channel 1240

[0124] The opening size of the first sound pickup hole 1210 on the shell 600 can be determined according to the design requirements of the earphone. It should be understood that the larger the aperture of the first sound pickup hole 1210 of the shell 600, the stronger the sound wave energy that can enter the shell 600 through the first sound pickup hole 1210, so that the earphone can have better sound pickup effect. Further consume the energy of wind noise, so that the wind noise entering the first microphone cavity 1220 is reduced.

[0125] The sound guide channel 1240 of the present disclosure can be specifically provided in the extension part 120, whereby the relatively large internal space in the extension part 120 can be utilized, so that it is more convenient to set the sound guide channel 1240 in the shell 600, and the structure of the earphone of the present disclosure is more reasonable and compact.

[0126] In some embodiments, referring to FIGS. 33-34, the shell 600 of the present disclosure is also provided with a second sound pickup hole 1230, the two ends of the second sound pickup hole 1230 can be in communication with the sound guide channel 1240 and the first microphone cavity 1220 respectively. Specifically, the second sound pickup hole 1230 is a hole structure provided on the solid structure in the shell 600, and the two ends of the second sound pickup hole 1230 are located on the inner wall of the sound guide channel 1240 and the inner wall of the first microphone cavity 1220 respectively.

[0127] At least part of the sound guide channel 1240 is arranged at an angle with the line connecting the first sound pickup hole 1210 and the second sound pickup hole 1230. It should be understood that the line connecting the first sound pickup hole 1210 and the second sound pickup hole 1230 is a straight line, and the at least part of the sound guide channel 1240 is arranged at an angle with the line connecting the first sound pickup hole 1210 and the second sound pickup hole 1230. The sound guide channel 1240 can be a curved channel structure or a bent channel structure.

[0128] It should be understood that if the sound guide channel 1240 is a straight channel, then the sound guide channel 1240 is the shortest channel path connecting the first sound pickup hole 1210 and the second sound pickup hole 1230, and the sound guide channel 1240 is a curved channel structure or a bent channel structure, which can increase the path of the sound guide channel 1240. This can make the path of the wind noise wave longer when passing through the sound guide channel 1240, so that the energy of the wind noise wave can be further consumed during the process of passing through the sound guide channel 1240, so as to further reduce the energy of the wind noise wave finally reaching the first microphone cavity 1220, so that the wind noise of the earphone of the present disclosure is further reduced during the call recording.

[0129] In addition, it should also be understood that, after the sound guide channel 1240 in the present disclosure is bent or folded, at least part of the inner wall of the sound guide channel 1240 and the first sound pickup hole 1210 are arranged at an angle, so that when the wind noise wave enters the sound guide channel 1240 through the first sound pickup hole 1210, the propagation direction of at least part of the wind noise wave can be directed towards the inner wall of the sound guide channel 1240, so that the wind noise wave is more fully contacted with the inner wall of the sound guide channel 1240, so that the energy of the wind noise wave can be further fully consumed, so as to further reduce the wind noise energy finally reaching the first microphone cavity 1220.

[0130] In some embodiments, referring to FIG. 33, the sound guide channel 1240 in the shell 600 in the present disclosure can include a first channel segment 1240a, a second channel segment 1240b and a third channel segment 1240c connected in sequence. The first channel segment 1240a, the second channel segment 1240b and the third channel segment 1240c are connected in sequence, wherein one end of the first channel segment 1240a away from the second channel segment 1240b is connected with the first sound pickup hole 1210, and one end of the third channel segment 1240c away from the second channel segment 1240b is connected with the first microphone cavity 1220 through the second sound pickup hole 1230. The first channel segment 1240a and the third channel segment 1240c are arranged at an angle with the second channel segment 1240b, so that the extension direction of the first channel segment 1240a and the extension direction of the third channel segment 1240c are different from the extension direction of the second channel segment 1240b, so that the path of the sound guide channel 1240 can be increased.

[0131] In addition, when the wind noise wave propagates in the sound guide channel 1240, the direction of the wind noise wave can be changed after the wind noise wave enters the second channel segment 1240b from the first channel segment 1240a, and the direction of the wind noise wave can be changed again after the wind noise wave enters the third channel segment 1240c from the second channel segment 1240b, so as to achieve the purpose of making the wind noise wave at least fully contact with the inner wall of the second channel segment 1240b and the third channel segment 1240c to consume the energy of the wind noise wave.

[0132] In addition, in other embodiments, the sound guide channel 1240 in the shell 600 in the present disclosure can also include a larger number of channel segments, and adjacent channel segments in each channel segment can be arranged at an angle, so that the path length of the sound guide channel 1240 can be further increased.

[0133] In some embodiments, as shown in FIG. 33, portions of the sound guide passage 1240 of the housing 600 are bent in a direction away from the line connecting the first sound hole 1210 and the second sound hole 1230, so that the sound guide passage 1240 has a relatively large spacing from the line connecting the first sound hole 1210 and the second sound hole 1230. Portions of the sound guide passage 1240 are bent in a direction toward the line connecting the first sound hole 1210 and the second sound hole 1230, so that the sound guide passage 1240 has a relatively small spacing from the line connecting the first sound hole 1210 and the second sound hole 1230.

[0134] It should be understood that if the sound guide passage 1240 is bent in a direction away from the line connecting the first sound hole 1210 and the second sound hole 1230, the sound guide passage 1240 will extend along the space on one side of the housing 600, and the space occupied by the sound guide passage 1240 in the housing 600 will be large, and accordingly, the space in the housing 600 for installing other components of the earphone will be compressed.

[0135] In the present disclosure, by bending portions of the sound guide passage 1240 in a direction away from the line connecting the first sound hole 1210 and the second sound hole 1230, and bending other portions of the sound guide passage 1240 in a direction toward the line connecting the first sound hole 1210 and the second sound hole 1230, the sound guide passage 1240 as a whole will not be bent in the same direction, and the sound guide passage 1240 can make full use of the space in the housing 600 adjacent to the line connecting the first sound hole 1210 and the second sound hole 1230, and the space in the housing 600 away from the line connecting the first sound hole 1210 and the second sound hole 1230, so that the sound guide passage 1240 does not occupy too much space in the housing 600, and the space in the housing 600 for installing other components of the earphone is more sufficient, so that the overall size of the housing 600 does not have to be set too large, and the structure of the earphone of the present disclosure is compact.

[0136] In addition, in other embodiments, portions of the sound guide passage 1240 can also be arranged on opposite sides of the line connecting the first sound hole 1210 and the second sound hole 1230, so that the sound guide passage 1240 can make full use of the space in the housing 600 on opposite sides of the line connecting the first sound hole 1210 and the second sound hole 1230, so that the structure of the earphone is further compact even if the sound guide passage 1240 has a large bending amplitude and a long path.

[0137] In some embodiments, referring to FIG. 33, the first sound pickup hole 1210 and the second sound pickup hole 1230 of the first housing 600 in the present disclosure are both directed towards the inner wall of the sound guide passage 1240. Specifically, the aperture of the end of the first sound pickup hole 1210 that is in communication with the sound guide passage 1240 is directed towards the inner wall of the first passage segment 1240a, and the aperture of the end of the second sound pickup hole 1230 that is in communication with the sound guide passage 1240 is directed towards the inner wall of the third passage segment 1240c. Thus, when the wind noise wave enters the sound guide passage 1240 through the first sound pickup hole 1210, it needs to turn around before it can continue to propagate within the sound guide passage 1240, and the wind noise wave needs to turn around before it can enter the first microphone cavity 1220 through the second sound pickup hole 1230. In this process, the wind noise wave can further contact the inner wall of the sound guide passage 1240, so that the energy of the wind noise wave can be further fully consumed, so as to further reduce the wind noise of the earphone of the present disclosure when recording a call.

[0138] In some embodiments, referring to FIG. 33, the earphone of the present disclosure further comprises a baffle 170, wherein a sound guide groove is formed on the inner wall of the housing 600. One end of the sound guide groove has a groove aperture, the baffle 170 is arranged in the housing 600, and the baffle 170 is sealed to the groove aperture of the sound guide groove, thereby forming the sound guide passage 1240. Correspondingly, the baffle 170 and the inner wall of the sound guide groove can constitute the inner wall of the sound guide passage 1240, and the second sound pickup hole 1230 can be formed on the inner wall of the sound guide groove. Of course, it should be understood that the second sound pickup hole 1230 can also be formed on the baffle 170b, and the specific position of the second sound pickup hole 1230 is not limited in the present disclosure. The housing 600 can be prepared by injection molding process, and the process difficulty of forming the sound guide passage 1240 in the housing 600 can be reduced by arranging the baffle 170, thereby reducing the manufacturing cost of the earphone of the present disclosure.

[0139] In some embodiments, the earphone of the present disclosure can further be provided with a windproof part (not shown in the figure), which is arranged at least one of the first sound pickup hole 1210, the second sound pickup hole 1230, and between the first sound pickup hole 1210 and the second sound pickup hole 1230. Thus, the sound wave that enters the housing 600 through the first sound pickup hole 1210 and eventually reaches the first microphone cavity 1220 will pass through the windproof part, so that at least part of the wind noise wave in the sound wave can be filtered by the windproof part to reduce the energy of the wind noise wave that eventually reaches the first microphone cavity 1220.

[0140] Specifically, the number of the windproof parts is not limited. When the windproof part is arranged at the first sound pickup hole 1210, the windproof part can be arranged at the opening of the first sound pickup hole 1210 on the surface of the shell 600, or arranged in the first sound pickup hole 1210. When the windproof part is arranged at the second sound pickup hole 1230, the windproof part can be arranged at the connection between the second sound pickup hole 1230 and the first microphone cavity 1220, or arranged in the second sound pickup hole 1230.

[0141] In the present disclosure, the windproof part can be arranged to include a first windproof part and a second windproof part, wherein the first windproof part can be arranged at the first sound pickup hole 1210, and the second windproof part can be arranged at the second sound pickup hole 1230. Specifically, the first sound pickup hole 1210 can be located between the first sound pickup hole 1210 and the sound guide channel 1240, so as to avoid the first windproof part being exposed outside the shell 600, and to facilitate the installation of the first windproof part. The second windproof part can be arranged between the second sound pickup hole 1230 and the sound guide channel 1240, so as to facilitate the installation of the second windproof part.

[0142] In some embodiments, referring to FIG. 33, FIG. 8 and FIG. 9, the earphone of the present disclosure can further be arranged to include a second microphone 400 arranged in the shell 600. The shell 600 is provided with a third sound pickup hole 1250 and a second microphone cavity 1260, the second microphone cavity 1260 is located inside the shell 600, and the second microphone 400 is arranged in the second microphone cavity 1260, so that the second microphone 400 can be located inside the shell 600, and the shell 600 can protect the second microphone 400. The third sound pickup hole 1250 is arranged on the surface of the shell 600, and one end of the third sound pickup hole 1250 communicates with the second microphone cavity 1260, so that the outside of the shell 600 can communicate with the second microphone cavity 1260 through the third sound pickup hole 1250. The sound waves outside the shell 600 can enter the second microphone cavity 1260 through the third sound pickup hole 1250, so that the sound waves are received by the second microphone 400 and converted into electrical signals.

[0143] Specifically, when the user uses the earphone of the present disclosure to make a call or record, the user's voice can enter the second microphone cavity 1260 through the third sound pickup hole 1250, and the user's voice is received by the second microphone 400 and converted into electrical signals. In this way, the user's voice can be received by the first microphone 310 and the second microphone 400 at the same time, so that the sound effect of the user's voice collected by the earphone of the present disclosure is better, and the call recording effect of the earphone is better.

[0144] Referring to FIGS. 5 and 6, the third sound pickup hole 1250 of the shell 600 is located on the side of the second sound pickup hole 1230 away from the first sound pickup hole 1210, so that the first sound pickup hole 1210 and the third sound pickup hole 1250 can be distributed on both sides of the second sound pickup hole 1230, so that the first sound pickup hole 1210 and the third sound pickup hole 1250 have a relatively large spacing. In this way, when the earphone of the present disclosure is worn on the user's ear, the first microphone 310 and the second microphone 400 can acquire the sound of different parts, so that the call recording effect of the earphone of the present disclosure is better.

[0145] In some embodiments, referring to FIGS. 5 and 6, the first sound pickup hole 1210 and the third sound pickup hole 1250 of the shell 600 in the present disclosure can be distributed and arranged on the outer walls of the opposite sides of the shell 600. Since the first sound pickup hole 1210 is opposite to the tragus 230 of the user's ear, correspondingly, the third sound pickup hole 1250 is located on the outer wall of the side of the shell 600 away from the tragus 230, so that the first sound pickup hole 1210 can be relatively close to the user's mouth 500, and the third sound pickup hole 1250 can be relatively far away from the user's mouth 500. In this way, the first microphone 310 in the first microphone cavity 1220 can fully acquire the sound emitted by the user, and the second microphone 400 in the second microphone cavity 1260 can fully acquire the sound in the environment, and the sound in the environment can be eliminated through a noise reduction algorithm, so that the earphone of the present disclosure has a good noise reduction effect.

[0146] Specifically, the second microphone cavity 1260 can be arranged in the extension 120, and correspondingly, the third sound pickup hole 1250 is arranged on the surface of the extension 120. Specifically, the third sound pickup hole 1250 can be arranged on the outer side 126 of the extension 120, so that when the user faces the wind, the inner side 127 of the extension 120 can block the wind noise, so that the wind noise cannot enter the third sound pickup hole 1250. In addition, the third sound pickup hole 1250 can also be prevented from being blocked by the concha cavity 221 of the user, so that the sound emitted by the user acquired by the third sound pickup hole 1250 is clearer.

[0147] In some embodiments, referring to FIG. 37, the distance between the first sound pickup hole 1210 and the second sound pickup hole 1230 on the shell 600 in the present disclosure can be greater than 13 mm, so that when the earphone of the present disclosure is a double-microphone noise reduction earphone, the noise reduction algorithm requirement can be met. The distance between the first sound pickup hole 1210 and the second sound pickup hole 1230 is represented by L17 in FIG. 37.

[0148] In some embodiments, as shown in FIG. 37, when the earphone of the present disclosure is worn on the ear, the angle between the line connecting the first sound pickup hole 1210 and the third sound pickup hole 1250 and the line connecting the user's mouth 500 and the third sound pickup hole 1250 is less than 13°. The angle between the line connecting the first sound pickup hole 1210 and the third sound pickup hole 1250 and the line connecting the user's mouth 500 and the third sound pickup hole 1250 is denoted by the angle m in FIG. 10.

[0149] In some embodiments, the cross-sectional area of the first sound pickup hole 1210, the cross-sectional area of the second sound pickup hole 1230, and the cross-sectional area of the third sound pickup hole 1250 of the housing 600 in the present disclosure are all greater than 0.7 mm2, so that the cross-sectional area of the first sound pickup hole 1210, the cross-sectional area of the second sound pickup hole 1230, and the cross-sectional area of the third sound pickup hole 1250 are relatively larger under the premise of meeting the process requirements of opening the first sound pickup hole 1210, the second sound pickup hole 1230, and the third sound pickup hole 1250 on the housing 600, so that the sounds obtained by the first microphone 310 and the second microphone 400 are clearer.

[0150] The cross-sectional area of the sound guide channel 1240 is greater than 0.7 mm2, so that the sound emitted by the user can pass through the sound guide channel 1240 relatively more clearly and be received by the first microphone 310. In addition, the cross-sectional area of the sound guide channel 1240 is set to be greater than 0.7 mm2, so that the elimination effect of wind noise passing through the sound guide channel 1240 is better.

[0151] In some embodiments, as shown in FIGS. 5 and 9, the housing 600 in the present disclosure can also be provided with a first sound outlet hole 150 and a second sound outlet hole 160. The first sound outlet hole 150 and the second sound outlet hole 160 are located on opposite sides of the housing 600. The housing 600 of the earphone can also be provided with a first loudspeaker and a second loudspeaker. The first loudspeaker can be opposite to the first sound outlet hole 150, so that the sound emitted by the first loudspeaker can be output through the first sound outlet hole 150. The second loudspeaker can be opposite to the second sound outlet hole 160, so that the sound emitted by the second loudspeaker can be output through the second sound outlet hole 160.

[0152] Specifically, the first sound outlet hole 150 can be arranged on the sound emitting portion 130 and located on the side of the sound emitting portion 130 facing the inner wall of the concha cavity 221, and the first sound outlet hole 150 can also be close to the ear canal opening 280, so that the sound emitted by the first loudspeaker is more easily passed through, so that the sound heard by the user when wearing the earphone of the present disclosure is clearer. The second sound outlet hole 160 can be arranged on the extension portion 120 and located on the outer side surface 126 of the extension portion 120, so that the first sound outlet hole 150 and the second sound outlet hole 160 are distributed on opposite sides of the housing 600.

[0153] The first sound outlet hole 150 is adjacent to the first sound pickup hole 1210, and the second sound outlet hole 160 is adjacent to the third sound pickup hole 1250.

[0154] In some embodiments, the earphone of the present disclosure further comprises a shell 600 and a first buffer 200a.

[0155] The shell 600 is the basic component of the earphone of the present disclosure, and can provide a mounting basis for other at least partial components of the earphone and serve the purpose of protecting the other at least partial components. The shell 600 can be made of a metal material, so that the shell 600 has better structural strength, thereby making the durability and reliability of the shell 600 better. Of course, the shell 600 can also be made of a polymer material, so that the shell 600 has a certain structural strength while being relatively light in weight. The specific material of the shell 600 is not limited in the present disclosure.

[0156] The shell 600 comprises a main body part 110, and the main body part 110 comprises a first support part 111. When the earphone of the present disclosure is worn on the ear 200 of a user, the first support part 111 is located on the antitragus 214 of the ear 200, and the outer wall of the first support part 111 is in contact with the antitragus 214 of the ear 200. It should be understood that the earphone as a whole can be hung on the ear 200 of the user, and the antitragus 214 can support the first support part 111. Correspondingly, the shell 600 makes the first support part 111 press on the antitragus 214 under the action of its own gravity, so that the shell 600 can be fixed on the ear of the user.

[0157] Specifically, the main body part 110 can be provided as a curved structural member, and the first support part 111 is located at the curved position of the main body part 110.

[0158] The first buffer 200a is arranged in the shell 600, and the first buffer 200a is located at the first support part 111. Specifically, the first buffer 200a is located on the inner wall opposite to the first support part 111 in the shell 600, and the first buffer 200a can be connected with the inner wall on the side of the first support part 111 in the shell 600, so that the first buffer 200a can be fixed in the shell 600. When the shell 600 is hung on the ear 200 of the user, the first buffer 200a will also be pressed at the ear root 214 of the user under the action of its own gravity. The first support part 111 and the first buffer 200a are both deformable structural parts, and the hardness of the first buffer 200a is less than the hardness of the shell 600, so that the texture of the first buffer 200a is relatively soft. When the shell 600 is hung on the ear 200 of the user, the ear root 214 can react on the first support part 111 and the first buffer 200a, so that the first support part 111 and the first buffer 200a can be deformed under force. The first support part 111 and the first buffer 200a can be deformed so that the first buffer 200a is fully fitted to the ear root 214 of the user through the first support part 111, so that the contact area between the first buffer 200a and the ear root 214 of the user through the first support part 111 is relatively large. This can reduce the pressure of the first support part 111 and the first buffer 200a acting on the ear root 214 of the user as a whole, so that the user's ear root 214 is more comfortable when the shell 600 is hung on the ear 200 of the user.

[0159] The hardness of the shell 600 is greater than the hardness of the first buffer 200a, so that the texture of the shell 600 is relatively hard. In this way, the shell 600 can have better structural strength, and the structural rigidity of the shell 600 can be improved. In this way, the earphone of the present disclosure is more stable when hung on the ear 200 of the user, so as to avoid the earphone from falling off the ear 200 of the user to some extent.

[0160] In addition, the first buffer 200a is arranged in the shell 600, so that no other components are arranged on the surface of the shell 600, thereby making the integrity of the surface of the shell 600 better.

[0161] In some embodiments, referring to FIG. 39, the shell 600 in the present disclosure is a one-piece structure, such that the main body 120a and the first support 111 are integrated. Specifically, the main body 120a and the first support 111 can be formed by the same material and the same process at one time, such that the joint between the main body 120a and the first support 111 does not have a joint mark, and the joint between the main body 120a and the first support 111 is a flat surface, so that the appearance of the shell 600 is more beautiful, and the preparation process of the shell 600 is relatively simpler. In addition, after the joint between the main body 120a and the first support 111 is a flat surface, the user's body feeling when the joint between the main body 120a and the first support 111 contacts the user's skin is more comfortable.

[0162] The thickness of the first support 111 of the shell 600 is smaller than the thickness of the main body 120a, such that the thickness of the first support 111 is thinner than the thickness of the main body 120a, so that when the first support 111 and the main body 120a are made of the same material, the first support 111 can be relatively easily deformed under force, so that when the user's ear root 214 acts on the first support 111, the first support 111 can be deformed under force to make the first buffer 200a also deformed under force. Thus, the first buffer 200a can be better deformed under force to fit the user's ear root 214, so that the earphone is more comfortable when worn on the user's ear 200.

[0163] The thickness of the main body 120a of the shell 600 is greater than the thickness of the first support 111, such that the thickness of the main body 120a of the shell 600 is thicker than the thickness of the first support 111, so that when the main body 120a and the first support 111 are made of the same material, the main body 120a has better structural rigidity and stability, so that the earphone has better stability when worn on the user's ear 200.

[0164] Therefore, by making the first support 111 and the main body 120a a one-piece structure, and by adjusting the thickness of the first support 111 and the main body 120a, the hardness of the first support 111 and the main body 120a can be conveniently adjusted, so that the preparation process difficulty of the shell 600 can be reduced.

[0165] In some embodiments, referring to FIGS. 1, 38-40, the shell 600 and the first buffer 200a in the present disclosure are elastic structural members, so that when the shell 600 is hung on the user's ear 200, the first buffer 200a can be elastically deformed under the action of the user's ear root 214. When the shell 600 is removed from the user's ear 200, the first buffer 200a is no longer acted on by the user's ear root 214, and the first buffer 200a can recover under the action of its own elastic force, so that the surface of the shell 600 can be prevented from collapsing when the earphone is not in use.

[0166] In some embodiments, referring to FIGS. 39 and 40, the housing 600 is sleeved on the first buffer 200a, and the circumferential outer wall of the first buffer 200a is in contact with the inner wall of the housing 600. Specifically, the inner diameter of the portion of the housing 600 for accommodating the first buffer 200a matches the outer diameter of the first buffer 200a, so that the housing 600 wraps the first buffer 200a. In this way, there is no gap between the housing 600 and the first buffer 200a, and when the housing 600 is subjected to an external force, the external force can be directly transmitted to the first buffer 200a, so that the first buffer 200a can be fully deformed under stress, so that the first buffer 200a is more fitted to the user's ear root 214, and the comfort of the housing 600 when hung on the user's ear 200 is improved.

[0167] In addition, the inner wall of the housing 600 and the circumferential outer wall of the first buffer 200a have no gap, which can also enable the first buffer 200a to support the housing 600 to some extent, so that the overall structure of the earphone of the present disclosure is more rigid.

[0168] In addition, in other embodiments, in order to reduce the material for manufacturing the housing 600, the first buffer 200a can also be arranged outside the housing 600.

[0169] In some embodiments, referring to FIGS. 39 to 41, the earphone of the present disclosure can also be provided with a support 300a, which is arranged in the housing 600 along the length direction of the housing 600, that is, the extension direction of the support 300a is the same as the extension direction of the housing 600, and the support 300a also penetrates the first buffer 200a in the housing 600. Part of the outer wall of the support 300a is in contact with the inner wall of the first buffer 200a, and another part of the outer wall of the support 300a is in contact with the inner wall of the housing 600. Specifically, the support 300a can be provided with a first part and a second part, and the first buffer 200a is provided with a through hole for the support 300a to penetrate. The first part of the support 300a penetrates the through hole of the first buffer 200a, so that the first part is sleeved by the first buffer 200a, and the outer wall of the first part is in contact with the inner wall of the through hole of the first buffer 200a. The second part of the support 300a is not penetrated by the first buffer 200a, and the outer wall of the second part is in contact with the inner wall of the housing 600.

[0170] Thus, the first portion of the support member 300a can be supported on the inner wall of the perforation of the first buffer member 200a, and further supported on the portion of the housing 600 corresponding to the first buffer member 200a, and the second portion of the support member 300a can be supported on the portion of the housing 600 dislocated from the first buffer member 200a, so that the support member 300a can be fully supported on each portion of the housing 600 in the length direction of the housing 600, so as to make the structure stability and rigidity of the earphone of the present disclosure better. The support member 300a can be made of a material with certain structural strength, such as a polymer or a metal material. Specifically, the support member 300a can be made of titanium metal material, so that the support member 300a has better structural strength while being lighter in weight.

[0171] In some embodiments, referring to FIGS. 39 to 41, the earphone of the present disclosure can further be provided with a wire 400a, which can be arranged in the housing 600 and fixed on the outer wall of the support member 300a, so that the wire 400a can be fixed in the housing 600. When the earphone of the present disclosure is applied to an earphone, other electronic components can also be arranged in the housing 600, and the wire 400a can be electrically connected with each electronic component, so that each electronic component can be electrically connected with each other to realize the sound emitting and receiving functions of the earphone.

[0172] Specifically, the wire 400a can be arranged along the length direction of the support member 300a, and each portion of the wire 400a in the length direction thereof can be connected with the outer wall of each portion of the support member 300a in the length direction thereof, so that the wire 400a can be more stably and reliably fixed in the housing 600. If the electronic components located on both sides of the first buffer member 200a are installed in the housing 600, the wire 400a can also be arranged through the first buffer member 200a to electrically connect the electronic components located on both sides of the first buffer member 200a. In addition, the outer wall of the wire 400a except the outer wall connected with the support member 300a can be attached to the inner wall of the first buffer member 200a and / or the inner wall of the housing 600, so that the first buffer member 200a can fully cover the wire 400a and the support member 300a inside, and the housing 600 can also fully cover the wire 400a and the support member 300a inside, so that the wire 400a and the support member 300a arranged in the housing 600 are more structurally stable.

[0173] In some embodiments, in order to fix the wire 400a to the support 300a, the wire 400a and the support 300a can be fixed by adhesion, so that the wire 400a and the support 300a are connected conveniently. Specifically, each part of the wire 400a in the length direction can be adhesively connected to the support 300a. When assembling the wire 400a and the support 300a, adhesive can be applied on the outer wall of the support 300a and / or the outer wall of the wire 400a, and then the wire 400a is pressed on the outer wall of the support 300a, so that the wire 400a is fixed to the support 300a.

[0174] In addition, in other embodiments, a mounting groove capable of accommodating the wire 400a can be formed on the outer wall of the support 300a. The wire 400a can be embedded in the mounting groove of the support 300a, and the inner wall of the mounting groove can serve the purpose of limiting the wire 400a. The inner wall of the shell 600 and the inner wall of the first buffer 200a can be pressed on the outer wall of the wire 400a on the side of the slot opening of the mounting groove, so that the wire 400a can be stably and reliably fixed in the mounting groove of the support 300a, and the wire 400a can also be fixed to the support 300a.

[0175] In some embodiments, the materials of the shell 600 and the first buffer 200a in the present disclosure can be silica gel. Specifically, the shell 600 is made of silica gel material with relatively high hardness, and the first buffer 200a is made of silica gel material with relatively low hardness, so that the hardness of the shell 600 is greater than the hardness of the first buffer 200a. The first buffer 200a and the shell 600 can be made by overmolding injection molding process. Specifically, the first buffer 200a can cover the support 300a and the wire 400a by overmolding injection molding process, so that the support 300a and the wire 400a are embedded in the first buffer 200a, and the support 300a and the wire 400a are tightly connected to the first buffer 200a. The shell 600 can be covered on the first buffer 200a, the support 300a and the wire 400a by overmolding injection molding process, so that the shell 600, the first buffer 200a, the support 300a and the wire 400a are tightly connected.

[0176] In addition, the shell 600 is made by overmolding injection molding process, so that the structure of the shell 600 is more integrated, and the surface of the shell 600 is relatively smoother, so as to improve the comfort of the user when using the earphone of the present disclosure.

[0177] In some embodiments, the Shore hardness of the first cushion 200a in the present disclosure is 0-10, and the Shore hardness of the shell 600 is 50-80. In this way, the hardness of the first cushion 200a is relatively low, and the texture is relatively soft, which can improve the wearing comfort of the earphone applying the present disclosure. The hardness of the shell 600 is relatively high, and the texture is relatively hard, which can improve the wearing stability of the earphone applying the present disclosure.

[0178] In some embodiments, the thickness of the first support part 111 of the shell 600 in the present disclosure can be set to 0.2mm-0.4mm, in this way, the thickness of the first support part 111 of the shell 600 is relatively thin. When the shell 600 is hung on the ear root 214 of the user, the ear root 214 can generate a force on the first support part 111, and the first support part 111 is more likely to deform after being stressed. The force can be transmitted to the first cushion 200a, so that the first cushion 200a is more likely to deform to fit the ear root 214 of the user.

[0179] In some embodiments, referring to FIGS. 38, 39 and 42, the main body part 110 of the shell 600 in the present disclosure can also be provided with a second support part 112. When the shell 600 is hung on the ear 200 of the user, the second support part 112 is opposite to and in contact with the back of the ear 215 of the user, and the back of the ear 215 of the user can limit the second support part 112, so that the shell 600 is more stably hung on the ear 200 of the user. The earphone in the present disclosure can also be provided with a second cushion 500a, which is also arranged in the shell 600, and the second cushion 500a is located in the second support part 112.

[0180] Specifically, the second cushion 500a is located in the shell 600 opposite to the second support part 112, and the second cushion 500a can be connected with the inner wall on one side of the shell 600, so that the second cushion 500a can be fixed in the shell 600. When the shell 600 is hung on the ear 200 of the user, the second cushion 500a is in contact with the back of the ear 215 of the user, so that the second cushion 500a interacts with the back of the ear 215 of the user. The second cushion 500a is also a deformable structure, and the hardness of the second cushion 500a is less than that of the shell 600, so that the texture of the second cushion 500a is relatively soft.

[0181] When the shell 600 is hung on the user's ear 200, the ear back 215 reacts on the second support portion 112 and the second buffer 500a, so that the second support portion 112 and the second buffer 500a can be deformed by force. The second support portion 112 and the second buffer 500a can be deformed so that the second buffer 500a contacts the user's ear back 215 through the second support portion 112 with a relatively larger area, which can reduce the pressure of the second support portion 112 and the second buffer 500a acting on the user's ear back 215 as a whole, so that the user's ear back 215 is more comfortable when the shell 600 is hung on the user's ear 200.

[0182] Since the force of the second support portion 112 and the second buffer 500a of the shell 600 on the user's ear back 215 is smaller than the force of the first support portion 111 and the first buffer 200a on the ear root 214, the thickness of the second buffer 500a can be set to be smaller than the thickness of the first buffer 200a, so that the user's ear back 215 still has better comfort. Correspondingly, the thickness of the second support portion 112 of the shell 600 can be set to be thicker than the first support portion 111, so that the structural rigidity of the second support portion 112 of the shell 600 is better.
