DETAILED DESCRIPTION

[0033] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0034] In the embodiments of the present application, it should be noted that, unless otherwise specified and limited, the term "connection" should be understood in a broad sense. For example, it can be an electrical connection or a connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0035] It should be noted that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order for the objects. It is understandable that the specific order or sequence of "first\second\third" can be interchanged where permitted. It should be understood that the objects distinguished by "first\second\third" can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0036] The following combination Figures 1 to 7 The stable-wearing earphone device described in the embodiment of the present application is described in detail.

[0037] The earphone device includes: a first earphone assembly 100 and a second earphone assembly 200, and a neck hanging body 300 connected to the first earphone assembly 100 and the second earphone assembly 200 respectively; the first earphone assembly 100 includes: a first sound-emitting body 110 and a first contact body 120, and a first ear hanging body 130 connected to the first sound-emitting body 110 and the first contact body 120 respectively; Figure 4As shown, the projection of the contours of the first ear hook body 130 and the first contact body 120 close to the second earphone assembly 200 on the XY plane of the second target coordinate system includes a third curve, the third curve includes a third minimum point E1, and the area corresponding to the first ear hook body 130 and the third minimum point E1 is used to contact the upper ear root of the wearer. The second target coordinate system takes the symmetry plane of the first earphone assembly 100 and the second earphone assembly 200 as the XZ plane, and the bottom surface of the annular portion 310 of the neck hanging body 300 as the YZ plane, and the positive direction of the Y axis is the direction from the XZ plane to the first earphone assembly 100.

[0038] 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 by hanging the neck hanging body 300 on the wearer's neck, and can prevent the first earphone assembly 100 from being detached from the left ear by hanging the first ear hanging body 130 on the wearer's left ear, thereby improving the user experience of the earphone device; in addition, the projection of the contours of the first ear hanging body 130 and the first contact body 120 close to the second earphone assembly 200 on the XY plane of the second target coordinate system includes a third curve, and the third curve includes a third minimum point E1. The area corresponding to the first ear hanging body 130 and the third minimum point E1 is used to contact the upper ear root of the wearer, so that the first ear hanging body 130 and the first contact body 120 with curved contours can make the first earphone assembly 100 fit more closely to the wearer's left ear, so that the first earphone assembly 100 can be more stably worn on the wearer's left ear, thereby further improving the user experience of the earphone device.

[0039] In the embodiments of the present application, Figure 3 As shown, the second earphone assembly 200 may include a second sound-emitting body 210 and a second contact body 220, and a second ear-hanging body 230 respectively connected to the second sound-emitting body 210 and the second contact body 220. The first earphone assembly 100 may be worn on the left ear of the wearer, and the second earphone assembly 200 may be worn on the right ear of the wearer.

[0040] 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 3As 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.

[0041] 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.

[0042] 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.

[0043] 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 can have a first end and a second end that are relatively arranged 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] It should be noted that the sound-emitting body described in this application can be the first sound-emitting body or the second sound-emitting body. The contact body described in this application can be the first contact body or the second contact body. The ear-hanging body described in this application can be the first ear-hanging body or the second ear-hanging body.

[0048] In the embodiment of the present application, the area corresponding to the first ear hook 130 and the third minimum point E1 can also be used to correspond to the position of the wearer's head, that is, the inner side surface of the area corresponding to the first ear hook 130 and the third minimum point E1 is used to contact the upper ear root of the wearer, and the side surface of the area corresponding to the first ear hook 130 and the third minimum point E1 is used to contact the wearer's head or be located on the wearer's head to ensure that the first ear hook 130 can be stably clamped in the concave upper ear root formed by the wearer's head and the wearer's ear.

[0049] Here, the third minimum point E1 may correspond to the corner position of the first ear hook 130, so that the two parts of the corner structure formed by the first ear hook 130 can further clamp the upper ear root of the wearer, thereby further improving the wearing stability of the earphone device. As an example, the first ear hook 130 may include a first part and a second part arranged in different directions; the first part is connected to the first sounding body 110, and the second part is connected to the first contact body 120; wherein the third minimum point E1 corresponds to the connecting part of the first part and the second part, so that the third minimum point E1 corresponds to the corner part formed by the first part and the second part, so that the upper ear root of the wearer can be further clamped by the corner part, thereby further improving the wearing stability of the earphone device.

[0050] In some optional implementations of the embodiments of the present application, such as Figure 4 and Figure 5As shown, the third curve may further include a third maximum point E2, the third maximum point E2 corresponds to the position of the first contact body 120, and the distance between the third maximum point E2 and the Y axis is greater than the distance between the third minimum point E1 and the Y axis; in the third curve, the distance between the third maximum point E2 and the X axis is the largest, and the distance between the third maximum point E2 and the Y axis is the largest; in the wearing state, the area corresponding to the first ear hanging body 130 and the third minimum point E1 is in contact with the upper ear root of the wearer, the area corresponding to the first contact body 120 and the third maximum point E2 is in contact with the wearer's head or located at the wearer's head, the distance between the third maximum point E2 and the X axis is the largest, and the distance between the third maximum point E2 and the Y axis is the largest, which can make the area corresponding to the first contact body 120 and the third maximum point E2 closer to the wearer's head and farther away from the wearer's ear; in addition, the area corresponding to the first contact body 120 and the third maximum point E2 is also farther away from the wearer's neck. At this time, the overall contact area between the earphone device and the wearer is larger, which can avoid the local squeezing discomfort caused by the smaller overall contact area between the earphone device and the wearer.

[0051] In this implementation, the area corresponding to the first contact body 120 and the third maximum point E2 may correspond to the position of the wearer's head. In the worn state, the area corresponding to the first contact body 120 and the third maximum point E2 is in contact with the wearer's head or is located at the wearer's head to ensure that the wearer's head stably supports the first contact body 120.

[0052] In this implementation, the third maximum point E2 may correspond to the corner position of the first contact body 120, so that the outer contour formed by the first contact body 120 and the first ear hook body 130 is smoother as a whole, thereby improving the wearing comfort and safety of the earphone device.

[0053] In this implementation, the third maximum point E2 is the first endpoint of the third curve, and the third curve may also include a second endpoint E3, which corresponds to the junction of the first ear hanging body 130 and the first sounding body 110; the distance between the second endpoint E3 and the Y axis is smaller than the distance between the third minimum point E1 and the Y axis, and the distance between the second endpoint E3 and the X axis is smaller than the distance between the third maximum point E2 and the X axis.

[0054] Here, the area of ​​the earphone device corresponding to the second endpoint E3 corresponds to the position of the wearer's ear. When worn, the area of ​​the earphone device corresponding to the second endpoint E3 is closer to the wearer's concha cavity to ensure the audio effect of the earphone device.

[0055] In this implementation, the distance between the third minimum point E1 and the third maximum point E2 is not limited; for example, the distance between the third minimum point E1 and the third maximum point E2 can be 15mm to 16mm; as an example, the distance between the third minimum point E1 and the third maximum point E2 can be 15.5mm; the distance between the third minimum point E1 and the third maximum point E2 in the Y-axis direction is not limited. For example, the distance between the third minimum point E1 and the third maximum point E2 in the Y-axis direction can be 14mm to 15mm. As an example, the distance between the third minimum point E1 and the third maximum point E2 in the Y-axis direction is 14.5mm. The distance between the third minimum point E1 and the third maximum point E2 in the X-axis direction is not limited. For example, the distance between the third minimum point E1 and the third maximum point E2 in the X-axis direction can be 4.5mm to 5.5mm. As an example, the distance between the third minimum point E1 and the third maximum point E2 in the X-axis direction can be 5mm. By setting the third minimum point E1 and the third maximum point E2 at appropriate positions, it is possible to ensure that the first ear hook 130 and the corresponding area of ​​the third minimum point E1 are in contact with the wearer's upper ear root, thereby ensuring the wearing stability of the first earphone assembly 100, and the first contact body 120 and the corresponding area of ​​the third maximum point E2 are in contact with the wearer's head or located on the wearer's head, thereby ensuring that the wearer's head can stably support the first contact body 120.

[0056] In this implementation, the distance between the third minimum point E1 and the second endpoint E3 is not limited. For example, the distance between the third minimum point E1 and the second endpoint E3 can be 26.5mm to 27.5mm; as an example, the distance between the third minimum point E1 and the second endpoint E3 is 27mm; the distance between the third minimum point E1 and the second endpoint E3 in the Y-axis direction is not limited; for example, the distance between the third minimum point E1 and the second endpoint E3 in the Y-axis direction can be 13.5mm to 14.5mm; as an example, the distance between the third minimum point E1 and the second endpoint E3 in the Y-axis direction is 14mm. The distance between the third minimum point E1 and the second endpoint E3 in the X-axis direction is not limited. For example, the distance between the third minimum point E1 and the second endpoint E3 in the X-axis direction can be 22.5mm to 23.5mm. As an example, the distance between the third minimum point E1 and the second endpoint E3 in the X-axis direction is 23mm. By setting the third minimum point E1 and the second endpoint E3 at appropriate positions, it can ensure that the area corresponding to the first ear hook 130 and the third minimum point E1 is in contact with the wearer's upper ear root, thereby ensuring the wearing stability of the first earphone assembly 100, and the area corresponding to the earphone device and the second endpoint E3 can be made closer to the wearer's concha cavity, thereby ensuring the audio effect of the earphone device.

[0057] In this implementation, if Figure 5As shown, the third minimum point E1 and the third maximum point E2 form a first straight line, and the first straight line forms a first angle E4 with the X-axis; the value of the first angle E4 is not limited. For example, the range of the first angle E4 can be 71 degrees to 73 degrees. As an example, the range of the first angle E4 can be 72 degrees. A suitable first angle E4 is set between the first straight line and the X-axis. In the wearing state, it can ensure that the first ear hook body 130 and the corresponding area of ​​the third minimum point E1 are in close contact with the upper ear root of the wearer, and the first contact body 120 and the corresponding area of ​​the third maximum point E2 are away from the wearer's ear, so that the overall contact area between the earphone device and the wearer is larger, which can avoid the discomfort of squeezing caused by the smaller overall contact area between the earphone device and the wearer.

[0058] In this implementation, if Figure 5 As shown, the third minimum point E1 and the second endpoint E3 form a second straight line, and the second straight line forms a second angle E5 with the X-axis; the value of the second angle E5 is not limited. For example, the second angle may range from 30 to 32 degrees. As an example, the second angle may be 31 degrees. A suitable second angle E5 is set between the second straight line and the X-axis. In the wearing state, it can ensure that the first ear hanging body 130 and the area corresponding to the third minimum point E1 are in close contact with the upper ear root of the wearer, and the area corresponding to the second endpoint E3 of the earphone device is closer to the wearer's concha cavity to ensure the audio effect of the earphone device; at the same time, the strength of the first sounding body 110 can be improved by the first ear hanging body 130, so that the first sounding body 110 can be more stably worn in the wearer's concha cavity.

[0059] In this implementation, the first ear hanging body 130 may be in a strip shape, so that the first ear hanging body 130 can connect the first sound-emitting body 110 and the first contact body 120 and ensure that the first ear hanging body 130 is smaller.

[0060] In some optional implementations of the embodiments of the present application, such as Figure 6 As shown, the axis of the first ear hook 130 located at the third minimum point E1 and the second endpoint E3 forms a third angle E6 with the XZ plane; the value of the third angle E6 is not limited. For example, the third angle may range from 34 to 36 degrees. As an example, the third angle may be 35 degrees. By setting a suitable third angle E6 for the first ear hook 130 located at the third minimum point E1 and the second endpoint E3, it is possible to reduce the contact area between the first ear hook 130 and the edge of the wearer's ear, thereby preventing the wearer from accumulating more sweat on the edge of the ear when wearing the earphone device during exercise; and it is possible to locate the area corresponding to the concha cavity of the first sounding body 110 at the wearer's concha cavity, thereby ensuring the audio effect of the earphone device.

[0061] 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.

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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.
