DETAILED DESCRIPTION

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The following combination Figures 1 to 6 The stable-wearing earphone device described in the embodiment of the present application is described in detail.

[0035] The earphone device includes: a first earphone assembly 100, a second earphone assembly 200 and a neck hanging body 300. The first earphone assembly 100 includes a first sound-emitting body 110; the first sound-emitting body 110 has a first tragus contact area and a first cavum concha corresponding area relative to each other; the second earphone assembly 200 includes a second sound-emitting body 210; the second sound-emitting body 210 has a second tragus contact area and a second cavum concha corresponding area relative to each other; the neck hanging body 300 is respectively connected to the first cavum concha corresponding area and the second cavum concha corresponding area; in the wearing state, there is a force between the first tragus contact area and the second tragus contact area to clamp the wearer's head.

[0036] In the related art, the earphone structure is fixed to the ear of the wearer by clamping it at the concha of the wearer. However, during use, the part of the earphone structure clamped at the concha of the wearer often comes out of the concha, 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 hanging body 300 on the neck of the wearer; at the same time, in the wearing state, there is a force between the first tragus contact area and the second tragus contact area to clamp the head of the wearer, so that the first tragus contact area fits tightly with the head of the wearer, and the second tragus contact area fits tightly with the head of the wearer, so that the first sound body 110 can be stably located at the ear of the wearer through the first tragus contact area, and the second sound body 210 can be stably located at the ear of the wearer through the second tragus contact area, so that the wearing stability of the earphone device can be greatly improved, and thus the user experience of the earphone device can be improved.

[0037] 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.

[0038] In some optional implementations of the embodiments of the present application, such as Figure 4 and Figure 5As shown, the projection of the bottom side contour formed by the first sound-emitting body 110 and the neck hanging body 300 on the XY plane of the first target coordinate system includes a first sub-curve, and the projection of the bottom side contour formed by the second sound-emitting body 210 and the neck hanging body 300 on the XY plane of the first target coordinate system includes a second sub-curve; the first target coordinate system takes the symmetry plane of the first earphone assembly 100 and the second earphone assembly 200 as the YZ plane, takes the bottom surface of the annular portion 310 of the neck hanging body 300 as the XZ plane, and the positive direction of the Y axis is the direction from the XZ plane to the top surface of the annular portion 310 of the neck hanging body 300; wherein the first sub-curve and the second sub-curve are symmetrical about the Y axis; since the first sound-emitting body 110 and the neck hanging body The projection of the bottom side contour formed by the second sounding body 210 and the neck hanging body 300 on the XY plane of the first target coordinate system includes a first sub-curve, which shows that the bottom side of the connection between the first sounding body 110 and the neck hanging body 300 is a smooth curved surface connection, thereby preventing the bottom side of the connection between the first sounding body 110 and the neck hanging body 300 from scratching the left ear of the wearer. Since the projection of the bottom side contour formed by the second sounding body 210 and the neck hanging body 300 on the XY plane of the first target coordinate system includes a second sub-curve, it can be seen that the bottom side of the connection between the second sounding body 210 and the neck hanging body 300 is a smooth curved surface connection, thereby preventing the bottom side of the connection between the second sounding body 210 and the neck hanging body 300 from scratching the right ear of the wearer.

[0039] In this implementation, the first sub-curve may include a first sub-minimum point C21, which corresponds to the position of the first sound-emitting body 110; the second sub-curve includes a second sub-minimum point C22, which corresponds to the position of the second sound-emitting body 210; wherein the distance L1 between the first sub-minimum point 21 and the second sub-minimum point C22 is not limited. For example, the distance L1 between the first sub-minimum point 21 and the second sub-minimum point C22 may be 29 mm to 31 mm; as an example, the distance L1 between the first sub-minimum point 21 and the second sub-minimum point C22 is 30 mm. By setting the distance L1 between the first sub-minimum point 21 and the second sub-minimum point C22 to a suitable size, the first sound-emitting body 110 and the second sound-emitting body 210 can have a suitable clamping force, which can not only ensure the stability of the position of the first sound-emitting body 110 and the second sound-emitting body 210 relative to the wearer, but also improve the wearing comfort of the earphone device.

[0040] Here, the first sub-minimum point 21 and the area corresponding to the first sound-emitting body 110 are close to the first tragus contact area; in the wearing state, the first tragus contact area contacts the wearer's tragus, and the neck hanging body 300 contacts the wearer's neck, that is, the earphone device has two supporting points at opposite ends of the area corresponding to the first concha cavity. At this time, the first tragus contact area is made as close to the X-axis side as possible through the first sub-minimum point 21, so that the supporting points of the first tragus contact area to the earphone device and the supporting points of the neck hanging body 300 to the earphone device can be more symmetrical relative to the area corresponding to the first concha cavity. Supporting the area corresponding to the first concha cavity by two relatively more symmetrical supporting points can further ensure that the area corresponding to the first concha cavity is stably located at the wearer's left concha cavity, thereby preventing the area corresponding to the first concha cavity from being relatively uneven. For rotation; the area corresponding to the second sub-minimum point 22 and the second sound-emitting body 210 is close to the second tragus contact area. In the wearing state, the second tragus contact area contacts the wearer's tragus, and the neck hanging body 300 contacts the wearer's neck, that is, the earphone device has two supporting points at the opposite ends of the area corresponding to the second concha cavity. At this time, the second tragus contact area is made as close to the X-axis side as possible through the second sub-minimum point 22, so that the supporting points of the second tragus contact area to the earphone device and the supporting points of the neck hanging body 300 to the earphone device can be more symmetrical relative to the area corresponding to the second concha cavity. Supporting the second concha cavity by two relatively more symmetrical supporting points can further ensure that the area corresponding to the second concha cavity is stably located at the right concha cavity of the wearer, thereby preventing the area corresponding to the second concha cavity from rotating relative to each other.

[0041] Here, in the wearing state, there is a force for clamping the wearer's head between the corresponding area of ​​the first sound body 110 and the first sub-minimum point C21 and the corresponding area of ​​the second sound body 210 and the second sub-minimum point C22. Through this clamping force, the first tragus contact area and the second tragus contact area can be in closer contact with the wearer's tragus, thereby ensuring that the wearer's tragus can stably support the first tragus contact area and the second tragus contact area; at the same time, through this clamping force, the corresponding area of ​​the first cavity concha and the corresponding area of ​​the second cavity concha can also be made to fit more closely with the wearer's cavity concha, thereby ensuring the audio effect of the first sound body 110 and the second sound body 210.

[0042] In this implementation, if Figure 4 and Figure 5As shown, the first sub-curve may include a first sub-maximum point C11, and the first sub-maximum point C11 corresponds to the junction of the first sound-emitting body 110 and the hanging neck body 300; the second sub-curve includes a second sub-maximum point C12, and the second sub-maximum point C12 corresponds to the junction of the second sound-emitting body 210 and the hanging neck body 300; wherein, the value of the distance L2 between the first sub-maximum point C11 and the second sub-maximum point C12 is not limited. For example, the distance L2 between the first sub-maximum point C11 and the second sub-maximum point C12 can be 57.5mm to 61.5mm. As an example, the distance L2 between the first sub-maximum point C11 and the second sub-maximum point C12 is 59.5mm. By setting the distance L2 between the first sub-maximum point C11 and the second sub-maximum point C12 to a suitable size, a suitable clamping force can be provided between the first sounding body 110 and the second sounding body 210 to ensure that the positions of the first sounding body 110 and the second sounding body 210 relative to the wearer are stable.

[0043] Here, in the wearing state, there is a force to clamp the wearer's head between the corresponding area of ​​the earphone device and the first sub-maximum point C11 and the corresponding area of ​​the earphone device and the second sub-maximum point C12; so that the connection between the sound-emitting body and the neck hanging body 300 fits tightly with the wearer's ear, thereby greatly improving the wearing stability of the earphone device, and further improving the stability of the audio effect of the earphone device.

[0044] In this implementation, if Figure 4 and Figure 5 As shown, the first sub-curve may include a first sub-minimum point C31, which corresponds to the position of the neck hanging body 300 and has the smallest distance from the X-axis; the second sub-curve includes a second sub-minimum point C32, which corresponds to the position of the neck hanging body 300 and has the smallest distance from the X-axis; wherein the value of the distance L3 between the first sub-minimum point C31 and the second sub-minimum point C32 is not limited. For example, the distance L3 between the first sub-minimum point C31 and the second sub-minimum point C32 may be 113 mm to 117 mm; as an example, the distance L3 between the first sub-minimum point C31 and the second sub-minimum point C32 is 115 mm. By setting the distance between the first sub-minimum point C31 and the second sub-minimum point C32 to a suitable size, the annular portion 310 of the neck hanging body 300 can fit more closely to the neck of the wearer.

[0045] Here, in the wearing state, there is a force to clamp the wearer's neck between the corresponding area between the neck hanging body 300 and the first sub-minimum point C31 and the corresponding area between the neck hanging body 300 and the second sub-minimum point C32; so that the annular part 310 of the neck hanging body 300 fits tightly against the wearer's neck, thereby greatly improving the wearing stability of the headphone device, and further improving the user experience of the headphone device.

[0046] In some optional implementations of the embodiments of the present application, the first earphone assembly 100 may further include a first ear-hanging body 130, which is connected to the first concha cavity corresponding area of ​​the first sound-emitting body 110; the second earphone assembly 200 also includes a second ear-hanging body 230, which is connected to the second concha cavity corresponding area of ​​the second sound-emitting body 210. By hanging the first ear-hanging body 130 on the left ear of the wearer, the wearing stability of the first earphone assembly 100 can be further improved, and by hanging the second ear-hanging body 230 on the right ear of the wearer, the wearing stability of the second earphone assembly 200 can be further improved. Meanwhile, by connecting the first ear hanging body 130 with the corresponding area of ​​the first concha cavity, the strength of the corresponding area of ​​the concha cavity of the first sounding body 110 can be improved, ensuring that the corresponding area of ​​the concha cavity of the first sounding body 110 can be stably located at the concha cavity of the wearer, thereby improving the audio stability of the first sounding body 110; by connecting the second ear hanging body 230 with the corresponding area of ​​the second concha cavity, the strength of the corresponding area of ​​the concha cavity of the second sounding body 210 can be improved, ensuring that the corresponding area of ​​the concha cavity of the second sounding body 210 can be stably located at the concha cavity of the wearer, thereby improving the audio stability of the second sounding body 210. In the related art, when the strength of the sounding body is not enough, the sounding body will shake relative to the concha cavity, thereby causing the problem that the audio sound of the sounding body appears loud and soft.

[0047] In some optional implementations of the embodiments of the present application, the first earphone assembly 100 may further include a first contact body 120, and the first ear hook body 130 is respectively connected to the first cavity concha corresponding area of ​​the first sound-emitting body 110 and the first contact body 120, and the second earphone assembly 200 may include a second contact body 220, and the second ear hook body 230 is respectively connected to the second cavity concha corresponding area of ​​the second sound-emitting body 210 and the second contact body 220.

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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.
