Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of sound-generating instruments, and in particular to an earphone. Background Art

[0002] Headphones have been widely used in people's daily lives. They can be used with mobile phones, computers and other electronic devices. According to the way users wear headphones, they can generally be divided into open-ear headphones and in-ear headphones. Among them, open-ear headphones can reduce damage to the sound channel. However, open-ear headphones are larger in size and are not suitable for people with smaller ears, which reduces the scope of application of headphones. Utility Model Content

[0003] The embodiment of the present application provides an earphone, which can reduce the volume of the earphone and increase the application range of the earphone.

[0004] The present application provides an earphone, comprising a main body, an extension and a sound-emitting part; one end of the main body is connected to the extension, and in a wearing state, one end of the main body away from the extension extends downward along the rear side of the ear; the end of the extension away from the main body bypasses the top of the helix of the ear and extends toward the concha cavity of the ear;

[0005] The sound-emitting portion is convexly arranged on a side of the extension portion facing the concha cavity, and in the direction of the human body's coronal axis, the sound-emitting portion and the extension portion are stacked, and the sound-emitting portion is located in the concha cavity of the ear when worn.

[0006] The earphone provided in this embodiment effectively improves space utilization by arranging the sound-emitting part on the side of the extension part facing the concha cavity, that is, arranging the sound-emitting part on the inner surface of the extension part, so that the sound-emitting part and the extension part are stacked in the direction of the human body's coronal axis. This design can make the overall size formed by the extension part and the sound-emitting part smaller, thereby making the size of the entire earphone smaller, more portable and lightweight, and convenient for people with smaller ears to wear, thereby improving the applicability of the earphone.

[0007] In a possible implementation, the side of the extension portion facing the tragus is defined as the outer side of the extension portion, the side of the extension portion facing the helix is ​​defined as the inner side of the extension portion, the side of the extension portion facing the outside of the human body is defined as the outer surface of the extension portion, and the side of the extension portion facing the cavum concha is defined as the inner surface of the extension portion;

[0008] Among them, the sound-emitting part is arranged on the inner surface of the extension part, and the end surface of the sound-emitting part facing away from the extension part is gradually inclined toward the direction of the ear hook plane from the inner side surface of the extension part to the outer side surface of the extension part, and / or the end surface of the sound-emitting part facing away from the extension part is gradually inclined toward the direction of the ear hook plane along the long axis of the extension part.

[0009] Such an inclined setting can not only reduce the size of the sound-emitting part, but also reduce the thickness of the earphone in the direction perpendicular to the ear hook plane, thereby making the entire earphone smaller, more portable and lightweight, and easier for people with small ears to wear. In addition, when worn, the sound-emitting part can not only better face the ear canal opening, improving the sound quality of the earphone; the end face of the sound-emitting part can also avoid the helix foot, thereby avoiding squeezing the helix foot, thereby improving wearing comfort.

[0010] In a possible implementation, an inclined angle between an end surface of the sound-emitting portion facing away from the extending portion and a plane where an inner surface of the extending portion is located is 22° to 28°.

[0011] Such a setting can make more effective use of limited space, improve space utilization, and thus make the headphones develop in the direction of miniaturization, so that the headphones can better adapt to the shape and size of the ears, which is not only conducive to the wearing comfort of the headphones, but also allows the sound-emitting part to be set relative to the ear canal opening, thereby making the sound quality of the headphones clearer and the audio experience better.

[0012] In a possible implementation, on the human coronal axis, the distance between the end surface of the sound-emitting portion facing away from the extension portion and the apex of the extension portion is 12 mm to 16 mm, and the apex of the extension portion is the highest point of the extension portion raised relative to the ear hook plane.

[0013] By limiting the distance between the end face of the sound-emitting portion away from the extension portion and the apex of the extension portion, the thickness of the earphone perpendicular to the ear hook plane can be made smaller, thereby reducing the size of the earphone, making it easier for users with smaller ears to wear, and improving the applicability of the earphone.

[0014] In a possible implementation, the axial thickness of the sound-emitting portion is less than 12 mm; and / or the maximum outer diameter of the sound-emitting portion is 10 mm to 15 mm.

[0015] This embodiment can reduce the size of the sound-emitting part by limiting the axial thickness of the sound-emitting part and the maximum outer diameter of the sound-emitting part, which is not only conducive to the development of headphones in the direction of miniaturization, but also can avoid the sound-emitting part squeezing the anti-tragus and the helix crus, making it suitable for users with small ears.

[0016] In a possible implementation, the extension portion includes a first arc segment, a long strip segment, and a second arc segment connected in sequence, the end of the first arc segment facing away from the long strip segment is connected to the main body, the end of the second arc segment facing away from the long strip segment is bent toward the concha cavity of the ear and connected to the sound-emitting portion; wherein the sound-emitting portion is arranged on a side of the second arc segment facing the concha cavity, and the sound-emitting portion and the second arc segment are stacked in the direction of the human body's coronal axis.

[0017] In this example, the end of the second arc segment facing away from the long strip segment is located in the concha cavity, and the distance between the extension portion and the antihelix is ​​increased, thereby preventing the extension portion from squeezing the antihelix and improving the wearing comfort of the earphone.

[0018] In addition, the sound-emitting part is arranged on the side of the second arc segment facing the concha cavity, so that the sound-emitting part and the second arc segment are stacked in the direction of the human body's coronal axis, which can effectively improve space utilization, facilitate reducing the volume of the extension part, and make the earphone develop in the direction of miniaturization.

[0019] In a possible implementation, the distance between the projection of the outer edge point of the sound-emitting portion on the ear hook plane and the projection of the outer side surface of the long strip segment on the ear hook plane is 3 mm to 5 mm.

[0020] By limiting the present embodiment, the distance between the projection of the outer edge point of the sound-emitting part on the ear hook plane and the projection of the outer side surface of the long strip segment on the ear hook plane can be shortened, thereby reducing the size of the sound-emitting part, making the sound-emitting part more miniaturized, and further miniaturizing the entire earphone.

[0021] In a possible implementation, the first arc segment includes at least one of the following features:

[0022] The width of the first arc segment in the direction of the human body sagittal axis is less than or equal to 15 mm;

[0023] The height of the first arc segment in the direction of the vertical axis of the human body is less than or equal to 12 mm;

[0024] Along the direction from the long strip to the main body, the cross-sectional area of ​​the first arc segment gradually decreases;

[0025] The cross-sectional area of ​​the first arc segment is no greater than 75 mm 2 .

[0026] By limiting the width L5 of the first arc segment in the direction of the human body's sagittal axis and / or the height of the first arc segment in the direction of the human body's vertical axis, and / or the cross-sectional area S of the first arc segment, the first arc segment of the extension portion can be miniaturized, thereby miniaturizing the extension portion and the earphone.

[0027] In a possible implementation, along the short axis direction of the long strip segment, the width of the long strip segment is greater than 11 mm and less than 15 mm, and / or the distance between the outer surface of the long strip segment and the inner surface of the long strip segment is less than or equal to 8 mm.

[0028] By limiting the width and thickness of the long strip segment, the long strip segment of the extension portion can be miniaturized, thereby miniaturizing the extension portion and the earphone.

[0029] In a possible implementation, when the device is worn, at least a portion of the sound-emitting portion is located within the tragus of the ear.

[0030] The sound-producing part is located in the concha cavity and at least partially within the tragus of the ear. With this arrangement, the sound-producing part is as close to the ear canal opening as possible without extending into the ear canal, thereby reducing pressure on the ear canal and damage to the ear canal, making it suitable for long-term wear.

[0062] As described in the background technology, the open-type earphones in the related art are relatively large in size and are not suitable for people with small ears. In view of the above technical problems, an embodiment of the present application provides an earphone, including a main body, an extension part and a sound-emitting part; one end of the main body is connected to the extension part, and in the wearing state, the end of the main body away from the extension part extends downward along the back side of the ear; the end of the extension part away from the main body bypasses the top of the helix of the ear and extends toward the concha cavity of the ear, and the sound-emitting part is located in the concha cavity of the ear; the sound-emitting part is convexly arranged on the side of the extension part facing the concha cavity, and the sound-emitting part and the extension part are stacked in the direction of the human coronal axis. The embodiment of the present application effectively improves the space utilization rate by stacking the sound-emitting part and the extension part in the direction of the human coronal axis. This design can make the overall size formed by the extension part and the sound-emitting part smaller, thereby making the size of the entire earphone smaller, more portable and lightweight, and convenient for people with small ears to wear, thereby improving the scope of application of the earphone.

[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0064] In order to facilitate a clear description of the structure of the earphones provided in the present application, the structure of the ear and the wearing state involved in the text, the front, back, upper and lower sides of the ear, the sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, vertical axis of the human body, and the definitions of X, Y, and Z directions will be explained below.

[0065] Please refer to the attached Figure 1 The ear 200 of the user may include structures such as a helix 210, a suprastragal notch 211, a concha 220, a tragus 230, an antitragus 240, an antihelix 250, an antihelix crus 251, an antihelix crus 252, a triangular fossa 260, a helix crus 270, an ear canal opening 280, and an earlobe 290. The concha 220 may include a cymba concha 222 and a cavum concha 221.

[0066] The “front side of the ear” mentioned in this application is a concept relative to the “back side of the ear”, the former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head, the “upper edge of the ear” refers to the outer edge of the ear's helix facing upwards, and the “lower edge of the ear” refers to the outer edge of the ear's helix facing downwards, and they are both aimed at the user's ear.

[0067] The sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, and vertical axis of the human body are defined as follows: As is well known, in the fields of medicine and anatomy, three basic planes of the human body, namely the sagittal plane, coronal plane, and horizontal plane, and three basic axes, namely the sagittal axis, coronal axis, and vertical axis, can be defined. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Accordingly, the sagittal axis refers to an axis perpendicular to the coronal plane along the front-back direction of the body, the coronal axis refers to an axis perpendicular to the sagittal plane along the left-right direction of the body, and the vertical axis refers to an axis perpendicular to the horizontal plane along the up-down direction of the body.

[0068] The definitions of X, Y, and Z directions are as follows: Figure 2 , taking the center of the ear canal opening 280 as the origin, establish a coordinate system. The direction pointing to the back of the ear and parallel to the sagittal axis is defined as the positive direction of the X axis; the direction pointing to the outside of the ear and parallel to the coronal axis is defined as the positive direction of the Y axis (i.e., the positive direction of the Y axis). Figure 3 To Attachment Figure 6 The direction pointing outward from the paper surface) is defined as the positive direction of the Z axis, which is parallel to the vertical axis and points to the top of the ear. It should be noted that the above direction definitions are only for the convenience of description. In accordance with the principle of the technical solution, the X, Y, and Z directions can be defined arbitrarily, including but not limited to the axial symmetry and angular symmetry of the above directions.

[0069] In order to facilitate the understanding and description of the shape of the earphones in a non-worn state or a worn state, the earphones can be projected onto a specific plane, and the earphones can be described by parameters related to the projection shape of the earphones on the specific plane. In the worn state, the earphones can be projected onto the sagittal plane of the human body to form a corresponding projection shape. In the non-worn state, the earphones can be projected onto the earhook plane to form a corresponding projection shape. The earhook plane can be determined as follows: place the earphones horizontally on a plane so that the back of the earphones fits into the plane, and the plane tangent to the back of the earphones can be used as the earhook plane; it is easy to understand that the plane tangent to the back of the earphones includes the plane tangent to most areas of the back of the earphones. Please refer to the attached Figure 7 , the earhook plane 300 is tangent to the back of the earphone, and there is a tangent point. In some embodiments, the earhook plane and the human body sagittal plane may have a certain angle, such as between 10° and 30°, and the earphone projected on the human body sagittal plane and the earhook plane may form a similar projection shape; of course, in some embodiments, the earhook plane and the human body sagittal plane are parallel, and the earphone projected on the human body sagittal plane and the earhook plane may form the same projection shape, so the human body sagittal plane may also be regarded as the earhook plane 300.

[0070] Please continue to refer to the attached Figure 5 , Attachment Figure 6 , Attachment Fig. 9 To Attachment Fig. 22 The earphone 100 provided in this embodiment includes a main body 110, an extension part 120 and a sound-generating part 130. One end of the main body 110 is connected to the extension part 120, and the end of the main body 110 away from the extension part 120 extends downward along the back side of the ear. That is, one end of the main body 110 is a connection end, and the other end is a free end, and the connection end of the main body 110 is used to connect to the extension part 120.

[0071] The end of the extension portion 120 away from the main body 110 extends toward the concha cavity of the ear, bypassing the top of the helix of the ear 200. That is, in the wearing state, the main body 110 and the extension portion 120 are respectively located at the front and back sides of the ear, so that the earphone 100 is hung on the helix of the ear 200.

[0072] The main body 110 is mainly used to be hung on the back of the ear and to balance with the extension 120 and the sound-emitting 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 110 can also be against the back of the ear, such as the ear root, earlobe, the head position behind the ear root, etc., so as to support the wearing of the earphone and facilitate the earphone to be stably worn on the ear. In some embodiments, the free end of the main body can be provided with a battery for powering the earphone, and can also be provided with an antenna, Bluetooth or other electronic components for communicating with other devices.

[0073] For the convenience of description, in some embodiments, in the wearing state, the ear root contact area on the earphone that contacts the ear root can be used as a boundary to divide the extension portion 120 and the main body 110. In short, in the wearing state, the main body 110 is mainly located at the rear side of the ear, and the extension portion 120 is mainly located at the front side of the ear 200, so that the earphone 100 can be hung on the helix of the ear 200. Of course, in some embodiments, the part with the smallest cross-sectional area on the earphone can be used as a boundary, in other words, along the direction of the earphone, the thinnest part of the earphone is used as a boundary to divide the main body 110 and the extension portion 120.

[0074] Please refer to the attached Figure 6 , Attachment Fig.11 and attached Fig.13 The sound-emitting portion 130 is convexly arranged on the side of the extension portion 120 facing the concha cavity, or in other words, the sound-emitting portion 130 is arranged on the side of the extension portion 120 facing the concha cavity, and the sound-emitting portion 130 and the extension portion 120 are stacked in the direction of the human coronal axis. In this way, the sound-emitting portion 130 and the extension portion 120 are stacked in the Y-axis direction, which effectively improves the space utilization rate. This design can make the overall size formed by the extension portion 120 and the sound-emitting portion 130 smaller, thereby making the appearance size of the entire earphone smaller, more portable and lightweight, and convenient for people with small ears to wear, thereby improving the application range of the earphone.

[0075] In some embodiments, the shape of the extension portion 120 can be a rectangular parallelepiped, a cylinder, a cone, or other regular or irregular strip-shaped three-dimensional structures. For ease of description, the structure of the extension portion 120 may be defined as follows.

[0076] Please refer to the attached Figure 4 , Attachment Figure 5 , Attachment Fig.11 And attached Fig.13, the side of the extension part 120 facing the tragus is defined as the outer side 126 of the extension part, the side of the extension part 120 facing the helix is ​​defined as the inner side 127 of the extension part, the side of the extension part 120 facing the outside of the human body is defined as the outer surface 124 of the extension part, and the side of the extension part 120 facing the cavum concha is defined as the inner surface 125 of the extension part. In addition, the direction from the outer surface 124 of the extension part to the inner surface 125 of the extension part may be the thickness direction of the extension part 120, the direction from the outer side 126 of the extension part to the inner side 127 of the extension part is the short axis direction of the extension part 120, that is, the width direction of the extension part 120; the direction from the end of the extension part 120 connected to the main body part 110 to the end of the extension part connected to the sound-emitting part 130 is defined as the long axis direction of the extension part 120, that is, the length direction of the extension part 120.

[0077] The sound-emitting portion 130 is disposed on the inner surface 125 of the extension portion and protrudes from the inner surface 125 of the extension portion. In the direction of the coronal axis of the human body, the sound-emitting portion 130 and the extension portion 120 are stacked. Therefore, in the wearing state, at least a portion of the inner surface 125 of the extension portion 120 can be higher than the suprasternal notch 211 in the Y-axis direction, and at least a portion of the sound-emitting portion 130 can be lower than the tragus in the Y-axis direction. Therefore, the sound-emitting portion 130 can extend into the concha cavity, and the sound-emitting portion 130 is closer to the ear canal opening than the extension portion 120, so that the sound of the earphone can enter the ear canal opening more easily, thereby improving the sound quality of the earphone.

[0078] In addition, since the sound-emitting part 130 includes a speaker, and the size of the speaker has a great relationship with the sound quality of the earphone, compared with the design that the sound-emitting part 130 is usually set inside the extension part 120 or the two are basically at the same height, in this embodiment, due to the stacking design of the sound-emitting part 130 and the extension part 120 in the direction of the human body's coronal axis, the short axis of the extension part 120 can be set narrower, that is, the extension part 120 can have a smaller width; at the same time, the sound-emitting part 130 can still have a large enough volume to accommodate a larger speaker. In this way, the narrower extension part 120 can reduce the squeezing of the auricle, antihelix and other areas, and is more beautiful; at the same time, the larger speaker can ensure that the earphone still has good sound quality.

[0079] In some embodiments, the end surface 134 of the sound-emitting portion facing away from the extension portion is inclined relative to the ear hook plane. Fig.11, the end surface 134 of the sound-emitting part away from the extension part is gradually tilted from the inner side surface 127 of the extension part to the outer side surface 126 of the extension part, towards the direction of the ear hook plane; in other words, the end surface 134 of the sound-emitting part 130 is gradually tilted from the inner side surface 127 of the extension part 120 to the outer side surface 126 of the extension part 120, in the opposite direction of the Y axis, so that in the wearing state, the entirety of the sound-emitting part 130 and the end surface 134 of the sound-emitting part away from the extension part can be closer to the concha cavity, the sound-emitting part 130 can not only better face the ear canal opening, improving the sound quality of the earphone, but also the end surface 134 of the sound-emitting part away from the extension part can avoid the helix crus, thereby avoiding squeezing the helix crus, thereby improving the wearing comfort. Moreover, such a tilted setting can also reduce the design size of the sound-emitting part 130, making it easier for people with smaller ears to wear, and can also make the appearance size of the entire earphone smaller, more portable and lightweight.

[0080] Furthermore, the end surface 134 of the sound-emitting portion away from the extension portion can also be gradually inclined toward the direction of the ear hook plane along the long axis of the extension portion 120. In other words, the end surface of the sound-emitting portion 130 can also be gradually inclined toward the opposite direction of the Y axis along the long axis of the extension portion 120 at the same time. Such an inclined setting can minimize the size of the sound-emitting portion 130 to the greatest extent, thereby making the size of the entire earphone smaller, more portable and lightweight, and easier for people with small ears to wear.

[0081] In some embodiments, an inclined angle α1 between an end surface of the sound-emitting portion 130 facing away from the extending portion 120 and a plane where the inner surface 125 of the extending portion is located is 22° to 28°.

[0082] It should be understood that the selection of the tilt angle α1 in this embodiment can be designed according to the orientation of the sound-emitting part 130 relative to the ear canal opening in an ideal state; for example, please refer to the attached Figure 8 , attached Figure 8 The part near the ear canal opening is the simulated body of the sound-emitting part 130. Based on the origin of the three-dimensional coordinate axis as a reference, we can define the following angle range to indicate the ideal angle of the sound-emitting part pointing to the center of the ear canal opening:

[0083] In a 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 speaker pointing to the center of the ear canal opening is between +10° and +80°.

[0084] In a 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 speaker pointing to the center of the ear canal opening is between -70° and +70°.

[0085] In a 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 speaker pointing to the center of the ear canal opening is between -70° and +70°.

[0086] The overlapping parts of the above three angle ranges form a spatial angle range, which is the best angle for indicating that the sound-emitting part 130 is pointing to the center point of the ear canal opening.

[0087] Based on the above theory, please refer to the attached Fig.14 , the value range of the tilt angle α1 provided in this embodiment is 22°~28°. Among them, the preset values ​​of the angle α1 are 22°, 22.5°, 23°, 23.5°, 24°, 24.5°, 25°, 25.5°, 26°, 26.5°, 27°27.5° and 28°. Preferably, the value of the tilt angle α1 is 27.5°. In this embodiment, the end surface 134 of the sound-emitting part away from the extension part and the inner surface 125 of the extension part have a preset tilt angle α1, so that when the sound-emitting part 130 is arranged relative to the ear canal opening, the sound-emitting part 130 can have an ideal angle pointing to the center point of the ear canal opening, so that the sound quality of the earphone is clearer and the audio experience is better; in addition, the limited space can be more fully utilized, the space utilization rate is improved, and the earphone 100 is developed in the direction of miniaturization, so that the earphone 100 can better adapt to the shape and size of the ear, which is conducive to the wearing comfort of the earphone.

[0088] In one possible implementation, please refer to the attached Fig.15 In the coronal axis direction, the distance L1 between the end face 134 of the sound-emitting part away from the extension part and the vertex of the extension part 120 is 12 mm to 16 mm, wherein the vertex 128 of the extension part 120 is the highest point of the extension part 120 raised relative to the ear hook plane. For example, the value of the distance L1 between the end face 134 of the sound-emitting part away from the extension part and the vertex 128 of the extension part 120 is 12 mm, 13 mm, 14 mm, 15 mm or 16 mm. In this embodiment, by limiting the distance L1 between the end face 134 of the sound-emitting part away from the extension part and the vertex of the extension part 120, the thickness of the earphone in the direction perpendicular to the ear hook plane can be made smaller, thereby reducing the size of the earphone, making it easier for users with smaller ears to wear, and improving the applicability of the earphone.

[0089] In some embodiments, please refer to the attached Fig.16 and attached Fig.17, the axial thickness L2 of the sound-emitting part 130 is less than 12 mm; and / or, the maximum outer diameter d1 of the sound-emitting part 130 is 10 mm to 15 mm, for example, the maximum outer diameter d1 of the sound-emitting part 130 is 10 mm. The thickness of the sound-emitting part 130 can be measured as follows: a vertical line is drawn from the geometric center of the end surface 134 of the sound-emitting part away from the extension part, and the vertical line can be considered as the central axis of the sound-emitting part, and the thickness of the sound-emitting part 130 on the central axis is the thickness L2 of the sound-emitting part; and the maximum outer diameter of the sound-emitting part 130 can be measured as follows: on the end surface of the sound-emitting part away from the extension part, the distance between the two outer edge points with the largest distance is measured as the maximum outer diameter d1 of the sound-emitting part 130. By limiting the axial thickness of the sound-emitting part 130 and the maximum outer diameter d1 of the sound-emitting part 130, the size of the sound-emitting part 130 can be reduced, which is not only conducive to the development of the earphone towards miniaturization, but also can avoid the sound-emitting part 130 from squeezing the antitragus and the helix crus, and is suitable for users with small ears.

[0090] In some embodiments, please continue to refer to the attached Fig.10 The extension portion 120 includes a first arc segment 121 , a long segment 123 , and a second arc segment 122 that are connected in sequence. That is, the long segment 123 is used to connect the first arc segment 121 and the second arc segment 122 .

[0091] Among them, the end of the first arc segment 121 away from the long strip segment 123 is connected to the main body 110, and the end of the second arc segment 122 away from the long strip segment 123 is bent toward the concha cavity 221 of the ear 200 and connected to the sound-generating part 130. Specifically, the end of the second arc segment 122 away from the long strip segment 123 is bent toward the concha cavity 221 in the three-dimensional space. On the one hand, the second arc segment 122 is not only gradually bent from the inner side surface 127 of the extension part to the outer side surface 126 of the extension part, presenting a visual effect of gradually narrowing in the short axis direction of the extension part 120, so that in the wearing state, the second arc segment 122 can avoid the antihelix and the concha cavity to prevent squeezing the ear; on the other hand, the outer surface of the second arc segment 122 is gradually curved from the connection surface with the long strip segment 123 to the end of the second arc segment 122 toward the inner side surface 126 of the extension part. The surface 125 is curved in the negative direction of the Y-axis, that is, in the Y-axis direction, from the long strip segment 123 to the second arc segment 122, the surface of the extension portion 120 is curved toward the negative direction of the Y-axis, presenting a visual effect that the end of the second arc segment 122 is thinner, so that when worn, the outer surface of the second arc segment 122 can avoid the antitragus to prevent the antitragus from being squeezed; on the other hand, the transition surface of the outer side of the second arc segment 122 facing the sound-emitting portion 130 is a concave surface, so that when worn, the concave surface can just provide an avoidance space for the tragus to prevent the extension portion 120 from squeezing the tragus.

[0092] The sound-emitting portion 130 is arranged on the side of the second arc segment 122 facing the concha cavity; in the direction of the human coronal axis, the sound-emitting portion 130 and the second arc segment 122 are arranged in layers; in other words, the sound-emitting portion 130 and the extension portion 120 are arranged in layers in the Y-axis direction, and the projection of the sound-emitting portion 130 on the ear hook plane and the projection of the second arc segment 122 on the ear hook plane at least partially overlap, which can effectively improve the space utilization rate, facilitate the reduction of the volume of the extension portion 120, and make the earphone 100 develop in the direction of miniaturization. On the other hand, the sound-emitting portion 130 can be made closer to the ear canal opening, thereby improving the sound quality of the earphone.

[0093] The first arc segment 121 may represent the arc segment of the extension 120 that crosses the helix but does not exceed the triangular fossa 260 of the ear 200; the long segment 123 and the second arc segment 122 may be bounded by the vertex of the extension 120 relative to the ear hook plane, the arc segment at the end of the extension 120 is the second arc segment, and the extension between the first arc segment 121 and the second arc segment 122 is the long segment 123, or in other words, the long segment 123 is a straight line segment extending from the triangular fossa 260 of the ear 200 to the cavum concha 221; the second arc segment 122 is the arc segment of the extension 120 that crosses the vertex and bends toward the cavum concha 221. The vertex 128 is the highest point of the extension 120 relative to the ear hook plane, and is located on the outer surface 124 of the extension.

[0094] It should be understood that the shape of the first arc segment 121 in this embodiment needs to match the top of the helix and the shape of the second arc segment 122 needs to match the concha cavity, that is, the first arc segment 121 and the second arc segment 122 are not regular shapes. Therefore, the inclined angle α1 in this embodiment can refer to the long strip segment 123, that is, the plane where the inner surface of the long strip segment is located represents the plane where the inner surface 125 of the extension portion is located. Exemplarily, there is an inclined angle α1 between the end surface of the sound-emitting portion 130 away from the extension portion 120 and the inner surface of the long strip segment 123, and the inclined angle α1 is 22° to 28°.

[0095] In one possible implementation, please refer to the attached Fig.18 , the distance L3 between the projection of the outer edge point 133 of the sound-emitting 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 to 7mm. For example, the value of the distance L3 is 3mm, 4mm, 5mm, 6mm or 7mm. Among them, the outer edge point 133 of the sound-emitting part is the point farthest from the outer side surface of the long strip segment 123 in the outer peripheral surface of the sound-emitting part 130 and the part away from the antihelix 250; a larger L3 may cause the sound-emitting part to squeeze the concha cavity on the lower side of the auricle, and cause the size of the sound-emitting part 130 to be too large.

[0096] By limiting L3, this embodiment can reduce the distance between the projection of the outer edge point 133 of the sound-emitting 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, thereby reducing the size of the sound-emitting part 130, making the sound-emitting part 130 more miniaturized, and thus making the entire earphone more miniaturized.

[0097] In some embodiments, please refer to the attached Fig.19 , the width L5 of the first arc segment 121 in the sagittal axis direction of the human body is less than or equal to 15 mm, and / or the height L4 of the first arc segment 121 in the vertical axis direction of the human body 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 portion 120 can be miniaturized, thereby miniaturizing the extension portion 120 and the earphone 100.

[0098] Please refer to the attached Fig.19 and attached Fig. 20 , along the direction from the long strip segment 123 to the main body 110, the cross-sectional area S1 of the first arc segment 121 gradually decreases; the maximum value of the cross-sectional area S1 of the first arc segment 121 is less than 75 mm 2 .

[0099] This embodiment is limited by 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, so that the first arc segment 121 of the extension portion 120 can be miniaturized, thereby making the extension portion 120 and the earphone 100 tend to be miniaturized.

[0100] Please refer to the attached Fig.21 and attached Fig. 22 , along the short axis direction of the long segment 123, the width L6 of the long segment 123 is greater than 11 mm and less than 15 mm. For example, the width L6 of the long segment 123 is 12 mm, 13 mm, 14 mm or 15 mm. The distance L7 between the outer surface of the long segment 123 and the inner surface of the long segment 123 is less than or equal to 8 mm, that is, the thickness of the long segment 123 is less than or equal to 8 mm. By limiting the width and thickness of the long segment 123, the long segment 123 of the extension portion 120 can be miniaturized, and thus the extension portion 120 and the earphone 100 tend to be miniaturized.

[0101] In some embodiments, when worn, at least part of the sound-emitting portion 130 is located within the tragus of the ear; that is, under the premise that the sound-emitting portion 130 is located in the cavum concha, at least part of the sound-emitting portion 130 is also located within the tragus of the ear. In some embodiments, the entirety of the sound-emitting portion 130 is located within the tragus of the ear. With this arrangement, the sound-emitting portion is ensured to be as close to the opening of the ear canal as possible, but will not extend into the ear canal, which can reduce the pressure on the ear canal and reduce damage to the ear canal, making it suitable for long-term wear.

[0102] It should be noted that the earphone 100 further includes a battery and a mainboard, wherein the battery is used to provide power output to the mainboard and the sound-emitting part 130. The battery can be arranged on the main body 110 or on the extension part 120. In one example, the battery is arranged at the end of the main body 110 away from the extension part 120, and the mainboard is arranged on the extension part 120, so that the battery, the mainboard and the sound-emitting part 130 are arranged opposite to each other, which can better balance the weight of the earphone 100 and provide a more comfortable wearing experience. In another example, the battery and the mainboard are arranged on the extension part 120 at intervals. In order to ensure the normal operation of the mainboard, a wire needs to be arranged between the battery and the mainboard, and the wire can be routed in the extension part; in this embodiment, by arranging the battery and the mainboard at intervals in the extension part 120, it is not necessary to route the wire in the main body 110, and the battery and the mainboard are both arranged in the extension part 120, which can shorten the length of the wire used to connect the battery and the mainboard, making the processing technology of the earphone 100 simpler and reducing the production cost of the earphone 100.

[0103] Please continue to refer to the attached Fig.12 , the cross-sectional area of ​​the main body 110 gradually increases along the direction away from the extension portion 120, that is, along the direction away from the extension portion 120, the cross-sectional area of ​​the main body 110 gradually increases. Fig.12 The cross-sectional area of ​​the main body 110 gradually increases from top to bottom. Compared with the technical solution in which the cross-sectional area of ​​the main body 110 is equal everywhere, the volume and weight of the main body 110 can be reduced, and the wearing comfort of the earphone is improved. Moreover, the cross-sectional area of ​​the end of the main body 110 away from the extension 120 is the largest. Under the premise of reducing the volume of the main body 110, the weight of the earphone can be better balanced, and the wearing comfort of the earphone can be improved.
