[0040] The following combination Figures 1 to 7 The stable-wearing earphone device described in the embodiment of the present application is described in detail.

[0041] The earphone device includes: a first earphone assembly 100 and a second earphone assembly 200.

[0042] In the related art, the earphone structure is fixed to the wearer's ear by clamping it at the wearer's concha cavity. However, during use, the part of the earphone structure clamped at the wearer's concha cavity often falls out of the concha cavity, causing the earphone structure to fall off easily, and the user experience of the earphone structure is poor. The earphone device of the present application can prevent the earphone device from falling off by hanging the neck body 300 on the wearer's neck, and can prevent the earphone device from being detached from the ear by hanging the ear hanging body on the wearer's ear, thereby improving the user experience of the earphone structure; in addition, the bottom side contour formed by the ear hanging body and the contact body of at least one earphone assembly of the first earphone assembly 100 and the second earphone assembly 200 includes a fourth curve as a projection on the XY plane of the third target coordinate system, and the fourth curve includes a first endpoint G3, and a fourth adjacent point G3 having a distance less than 1 mm from the first endpoint G3. G0, the first endpoint G3 corresponds to the junction of the ear hook and the sound-emitting body, and the angle between the line between the first end G3 and the fourth adjacent point G0 and the positive direction of the X-axis is greater than 90 degrees and less than 120 degrees; by tilting the line between the first endpoint G3 and the fourth adjacent point G0 away from the contact body, the contact area between the ear hook and the edge of the wearer's ear can be reduced to prevent the wearer from accumulating more sweat on the edge of the ear when wearing the earphone device during exercise, and the ear hook can be made to contact the upper ear root of the wearer more closely to further improve the wearing stability of the earphone device.

[0043] In the embodiment of the present application, the structure of the sound-emitting body is not limited. For example, the sound-emitting body can be a rectangular parallelepiped structure. As an example, Figure 1 and Figure 3 As shown, the sound-emitting body may have a relatively large dimension in the length direction, a relatively small dimension in the width direction, and a smallest dimension in the thickness direction; in the worn state, the outer side surface of the sound-emitting body in the thickness direction is in an exposed state, and the inner side surface of the sound-emitting body in the thickness direction is in a hidden state, a portion of the inner side surface of the sound-emitting body in the thickness direction contacts the wearer's tragus, and a portion of the inner side surface of the sound-emitting body in the thickness direction corresponds to the position of the wearer's concha cavity.

[0044] In the embodiment of the present application, the structure of the contact body is not limited. For example, the contact body can be a strip structure. As an example, Figure 1 and Figure 2 As shown, the contact body can have a relatively large dimension in the length direction, a relatively small dimension in the width direction, and a smallest dimension in the thickness direction; in the worn state, the outer side surface of the contact body in the thickness direction is in an exposed state, and the inner side surface of the contact body in the thickness direction is in a hidden state, and the portion of the inner side surface of the contact body in the thickness direction is used to contact the wearer's head.

[0045] In the embodiment of the present application, the structure of the ear hook body is not limited. For example, the ear hook body can be a strip structure.

[0046] The connection position of the ear hook body and the contact body is not limited. For example, the ear hook body can be connected to the side of the contact body. For another example, the contact body has a first end and a second end that are arranged opposite to each other in the length direction. The ear hook body is connected to the second end of the contact body. As an example, the ear hook body is connected to the side of the second end of the contact body.

[0047] The method of connecting the ear hanging body and the contact body is not limited. For example, the ear hanging body and the contact body can be fixedly connected by a snap-fit ​​structure, bonding, welding, etc. Of course, the ear hanging body and the contact body can also be different parts of a structural member.

[0048] The connection position between the ear hook and the sound-emitting body is not limited. For example, the ear hook can be connected to the side of the sound-emitting body. For another example, the sound-emitting body has a relative tragus contact area and a concha corresponding area, and the ear hook can be connected to the concha corresponding area of ​​the sound-emitting body. As an example, the ear hook can be connected to the outer side of the concha corresponding area of ​​the sound-emitting body.

[0049] The connection method between the ear hook and the sound source is not limited. For example, the ear hook and the sound source can be fixedly connected by a snap-fit ​​structure, bonding, welding, etc. Of course, the ear hook and the sound source can also be different parts of a structural member.

[0050] It should be noted that the sound-emitting body described in the present application may be the first sound-emitting body 110 or the second sound-emitting body 210. The contact body described in the present application may be the first contact body 120 or the second contact body 220. The ear hanging body described in the present application may be the first ear hanging body 130 or the second ear hanging body 230.

[0051] In the embodiment of the present application, the area of ​​the earphone device corresponding to the first endpoint G3 can correspond to the position of the wearer's ear; when worn, the area of ​​the earphone device corresponding to the first endpoint G3 is in contact or close to the wearer's ear to ensure that the sound-emitting body is more closely attached to the wearer's ear.

[0052] As an example, the area of ​​the earphone device corresponding to the first endpoint G3 is used to be close to the corresponding area of ​​the concha of the sound-emitting body; when worn, the area of ​​the earphone device corresponding to the first endpoint G3 is close to the concha of the wearer, and the ear hook is connected to the position of the sound-emitting body close to the corresponding area of ​​the concha, which can improve the strength of the corresponding area of ​​the concha of the sound-emitting body, so that the corresponding area of ​​the concha of the sound-emitting body can be more stably located in the concha of the wearer, thereby ensuring the audio effect of the earphone device.

[0053] In some optional implementations of the embodiments of the present application, the fourth curve may further include a fourth point G4, the corresponding area of ​​the fourth point G4 is located at the junction of the ear hook body and the contact body, and is used to contact the wearer's head; the distance between the first end point G3 and the X axis is smaller than the distance between the fourth point G4 and the X axis; the distance between the first end point G3 and the Y axis is smaller than the distance between the fourth point G4 and the Y axis. By contacting the wearer's head at the junction of the ear hook body and the contact body, the earphone device can be more stably worn on the wearer's ear, thereby further improving the wearing stability of the earphone device.

[0054] In this implementation, the distance between the first endpoint G3 and the fourth point G4 is not limited. For example, the distance between the first endpoint G3 and the fourth point G4 can be 24mm to 26mm. As an example, the distance between the first endpoint G3 and the fourth point G4 can be 25mm. The distance between the first endpoint G3 and the fourth point G4 in the X-axis direction is not limited. For example, the distance between the first endpoint G3 and the fourth point G4 in the X-axis direction can be 16mm to 17mm. As an example, the distance between the first endpoint G3 and the fourth point G4 in the X-axis direction can be 16.5mm. The distance between the first endpoint G3 and the fourth point G4 in the Y-axis direction is not limited. For example, the distance between the first endpoint G3 and the fourth point G4 in the Y-axis direction can be 18mm to 19mm; as an example, the distance between the first endpoint G3 and the fourth point G4 in the Y-axis direction can be 18.5mm. By setting the first endpoint G3 and the fourth point G4 at appropriate positions, the area corresponding to the earphone device and the first endpoint G3 can be brought closer to the wearer's concha cavity to ensure the audio effect of the sound-emitting body; and the area corresponding to the earphone device and the fourth point G4 can be brought into contact with the wearer's head to improve the wearing stability of the earphone device.

[0055] In this implementation, the fourth curve may also include a fourth maximum point G1, the area corresponding to the fourth maximum point G1 is located on the side of the ear hook body close to the contact body, the distance between the fourth maximum point G1 and the Y axis is smaller than the distance between the fourth point G4 and the Y axis, and the distance between the fourth maximum point G1 and the X axis is the largest.

[0056] Here, the area corresponding to the earphone device and the fourth maximum point G1 is used to be spaced apart from the upper ear of the wearer. In the worn state, there is a gap between the area corresponding to the earphone device and the fourth maximum point G1 and the upper ear of the wearer. Since the area corresponding to the fourth maximum point G1 is located on the side of the ear hook close to the contact body, it can ensure that the weight of the contact body will not be pressed on the upper ear of the wearer in the worn state, thereby reducing the force on the upper ear of the wearer and improving the wearing comfort of the earphone device. Here, the weight of the contact body is mainly supported by the wearer's head.

[0057] Here, the distance between the fourth maximum point G1 and the fourth point G4 is not limited; for example, the distance between the fourth maximum point G1 and the fourth point G4 can be 4mm to 5mm; as an example, the distance between the fourth maximum point G1 and the fourth point G4 can be 4.5mm. The distance between the fourth maximum point G1 and the fourth point G4 in the X-axis direction is not limited; for example, the distance between the fourth maximum point G1 and the fourth point G4 in the X-axis direction can be 3.5mm to 4.5mm; as an example, the distance between the fourth maximum point G1 and the fourth point G4 in the X-axis direction can be 4mm. The distance between the fourth maximum point G1 and the fourth point G4 in the Y-axis direction is not limited; for example, the distance between the fourth maximum point G1 and the fourth point G4 in the Y-axis direction can be 0.5mm to 1.5mm; as an example, the distance between the fourth maximum point G1 and the fourth point G4 in the Y-axis direction can be 1mm. By setting the fourth maximum point G1 and the fourth point G4 at appropriate positions, the force on the upper ear root of the wearer can be reduced and the wearing comfort of the earphone device can be improved; and the area corresponding to the earphone device and the fourth point G4 can be made to contact the wearer's head to improve the wearing stability of the earphone device.

[0058] In this implementation, the fourth curve may also include a fourth minimum point G2; the fourth minimum point G2 corresponds to the position of the contact body and has the smallest distance from the X-axis of the third target coordinate system; the distance between the fourth minimum point G2 and the Y-axis is greater than the distance between the fourth point G4 and the Y-axis.

[0059] Here, the area corresponding to the contact body and the fourth minimum point G2 is used to correspond to the position of the wearer's head. In the wearing state, the area corresponding to the contact body and the fourth minimum point G2 is in contact with the wearer's head or is located at the wearer's head. The area corresponding to the contact body and the fourth minimum point G2 can be located at the first end of the contact body. The first end of the contact body can have a force contact area for contacting the wearer's head. Since the fourth minimum point G2 is closest to the X-axis and farthest from the Y-axis, the distance between the force contact area of ​​the first end of the contact body and the force contact area of ​​the ear hook can be increased, so that the weight of the contact body can be supported by the head far away from the upper ear root, thereby increasing the overall force area of ​​the wearer wearing the headphone device and reducing the force value of the local area of ​​the wearer wearing the headphone device, thereby improving the wearing comfort of the headphone device.

[0060] Here, the distance between the fourth minimum point G2 and the fourth point G4 is not limited; for example, the distance between the fourth minimum point G2 and the fourth point G4 can be 44.5mm to 46.5mm; as an example, the distance between the fourth minimum point G2 and the fourth point G4 can be 45.5mm. The distance between the fourth minimum point G2 and the fourth point G4 in the X-axis direction is not limited; for example, the distance between the fourth minimum point G2 and the fourth point G4 in the X-axis direction can be 25mm to 26mm; as an example, the distance between the fourth minimum point G2 and the fourth point G4 in the X-axis direction can be 25.5mm. The distance between the fourth minimum point G2 and the fourth point G4 in the Y-axis direction is not limited; for example, the distance between the fourth minimum point G2 and the fourth point G4 in the Y-axis direction can be 37.5mm to 38.5mm; as an example, the distance between the fourth minimum point G2 and the fourth point G4 in the Y-axis direction can be 38mm. By setting the fourth minimum point G2 and the fourth point G4 at appropriate positions, the distance between the force contact area of ​​the contact body and the force contact area of ​​the ear hook body can be increased so that the weight of the contact body can be supported by the head which is farther away from the upper ear root, thereby increasing the overall force area of ​​the earphone device and further improving the wearing comfort of the earphone device; and the area corresponding to the earphone device and the fourth point G4 can be made to contact the wearer's head to improve the wearing stability of the earphone device.

[0061] Here, the fourth minimum point G2 may correspond to the corner position of the contact body, that is, the corner position of the contact body is also a smooth curved surface structure, which can prevent the sharp-angled contact body from scratching the wearer, thereby improving the wearing safety of the earphone device.

[0062] In this implementation, if Figure 5 As shown, the fourth point G4 and the first endpoint G3 form a first straight line G6, and the first straight line forms a first angle G6 with the X-axis; the value of the first angle G6 is not limited. For example, the range of the first angle G6 can be 47 degrees to 49 degrees. As an example, the first angle G6 can be 48 degrees. Setting a suitable first angle G6 between the first straight line and the X-axis can not only make the area corresponding to the first endpoint G3 of the earphone device closer to the wearer's concha cavity, ensuring that the sound-emitting body is more closely attached to the wearer's ear; but also make the area corresponding to the fourth point G4 of the earphone device contact with the wearer's head, so as to improve the wearing stability of the earphone device.

[0063] In this implementation, if Figure 5As shown, the fourth point G4 and the fourth minimum point G2 can form a second straight line, and the second straight line forms a second angle G5 with the X-axis; the value of the second angle G5 is not limited. For example, the range of the second angle G5 can be 56 degrees to 58 degrees. As an example, the second angle G5 can be 57 degrees. Setting a suitable second angle G5 between the second straight line and the X-axis can not only increase the distance between the force contact area of ​​the contact body and the force contact area of ​​the ear hook body, so that the weight of the contact body can be supported by the head far away from the upper ear root, thereby increasing the overall force area of ​​the earphone device, and then improving the wearing comfort of the earphone device; but also enable the earphone device to contact the wearer's head with the area corresponding to the fourth point G4, so as to improve the wearing stability of the earphone device.

[0064] In some optional implementations of the embodiments of the present application, such as Figure 6 As shown, at least one of the first contact body 120 and the second contact body 220 forms a third angle G7 with the XZ plane through a neutral plane A7 perpendicular to the width direction; the value of the third angle G7 is not limited. For example, the third angle may range from 55 degrees to 57 degrees. As an example, the third angle may be 56 degrees. By setting a suitable third angle G7 between the neutral plane A7 perpendicular to the width direction of the contact body and the XZ plane, the contact body can be closely fitted to the wearer's head, so that the wearer's head can stably support the contact body.

[0065] In some optional implementations of the embodiments of the present application, the sound-emitting body may include a top shell and a bottom shell, and the top shell and the bottom shell may be connected by snapping, welding, bonding, etc., and a cavity of the sound-emitting body is defined between the top shell and the bottom shell. The earphone device may also include a sound-emitting component 400, and the sound-emitting component 400 may be disposed in the cavity of the sound-emitting body, and audio information may be provided through the sound-emitting component 400; the structure of the sound-emitting component 400 is not limited.

[0067] In the embodiment of the present application, the shape of the neck hanging body 300 is not limited. For example, the neck hanging body 300 can be a strip structure. The cross-sectional shapes of the neck hanging body 300 at different locations can be the same or different. Figure 3 As shown, the neck hanging body 300 may include: an annular portion 310, a first extension portion 320 and a second extension portion 330. The shapes of the cross sections of the annular portion 310, the first extension portion 320 and the second extension portion 330 may be the same or different. As an example, the cross-sectional area of ​​the annular portion 310 is the same at various locations, where the same cross-sectional area means that the cross-sectional shape is the same and the size of the cross section is the same. As another example, the cross-sectional contour line of the neck hanging body 300 is a curve, that is, there is no sharp corner area on the outside of the neck hanging body 300, thereby improving the safety of the contact between the neck hanging body 300 and the wearer's neck.

[0068] The cross-section of the annular portion 310 of the neck hanging body 300 may be a circular structure, and the diameter of the circular structure is not limited; in one application, the diameter of the circular structure may be 3.5 mm to 4.5 mm; as an example, the diameter of the circular structure may be 4 mm. By setting the cross-section of the annular portion 310 to a circular structure of appropriate size, the discomfort caused by the annular portion 310 of the neck hanging body 300 with sharp corners to the wearer can be eliminated, and the contact between the annular portion 310 and the wearer's neck can be ensured. Of course, in other embodiments, the cross-section of the annular portion 310 of the neck hanging body 300 may also be a non-circular structure; for example, the cross-section of the annular portion 310 of the neck hanging body 300 is elliptical.

[0069] like Figure 3 As shown, the neck hanging body 300 may include: an annular portion 310, a first extension portion 320 and a second extension portion 330. The first extension portion 320 is connected to the annular portion 310 and the first sound-emitting body 110 respectively; the second extension portion 330 is connected to the annular portion 310 and the second sound-emitting body 210 respectively; wherein the area of ​​at least one of the first extension portion 320 and the second extension portion 330 close to the sound-emitting body is used to contact the position of the wearer's ear helix, such as Figure 1 As shown, the neck hanging body 300 is supported by the wearer's ear helix to prevent the neck hanging body 300 from driving the first sound emitting body 110 and the second sound emitting body 210 to move.

[0070] Here, the cross-sectional area of ​​the first extension portion 320 on the side close to the first sound-emitting body 110 can gradually increase as it approaches the first sound-emitting body 110, so that the first extension portion 320 can be connected to the first sound-emitting body 110 through a larger cross-sectional area, thereby improving the connection strength between the first extension portion 320 and the first sound-emitting body 110; at the same time, the first extension portion 320 can also be connected to the annular portion 310 with a smaller cross-sectional area through a smaller cross-sectional area, so as to ensure that the connection area between the first extension portion 320 and the annular portion 310 is neat and flat. The cross-sectional area of ​​the second extension part 330 close to the second sound-emitting body 210 can be gradually increased as it approaches the second sound-emitting body 210, so that the second extension part 330 can be connected to the second sound-emitting body 210 through a larger cross-sectional area, thereby improving the connection strength between the second extension part 330 and the second sound-emitting body 210; at the same time, the second extension part 330 can also be connected to the annular part 310 with a smaller cross-sectional area through a smaller cross-sectional area, so as to ensure that the connection area between the second extension part 330 and the annular part 310 is neat and flat. Of course, in other examples, the cross-sectional areas of the first extension part 320 and the second extension part 330 can also remain unchanged everywhere.

[0071] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
