[0035] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 11As shown, the utility model designs an earphone fixing structure, which includes an ear wing 20, which is connected to the earphone and has a supporting end 24. When the earphone is located in the concha cavity 42, the ear wing 20 is limited to the concha cavity 42 of the human ear, and the supporting end 24 abuts against the end area of ​​the helix crus 41, and the end area is far away from the ear canal.

[0038] It should be noted that when wearing the earphone of the present invention, the ear wing 20 will be limited to the concha cavity 42 of the human ear, and the supporting end 24 of the ear wing 20 will abut the terminal area of ​​the helix crus 41 of the ear. The terminal area of ​​the helix crus 41 is thick, and will not cause pain due to the pressure of the ear wing 20, thereby ensuring the wearing comfort and solving the problem of the ear wing 20 abutting the concha 40 of the ear in the prior art, and the thin skin of the concha 40 is easy to cause pain. Of course, it should be noted that the terminal area of ​​the present invention refers to the end of the helix crus 41 away from the ear canal, such as point A. The connection method of the ear wing 20 and the earphone can be a fixed connection, for example, the ear wing 20 and the earphone are integrally formed, and the connection method of the ear wing 20 and the earphone can also be a detachable connection, for example, the ear wing 20 is connected to the earphone through a detachable movable part or the ear wing 20 is provided with a connection structure to connect to the earphone.

[0039] Specifically, the ear wing 20 includes an upper arc edge 21 and a lower arc edge 22. The upper arc edge 21 is parabolic and bends upward or downward. The lower arc edge 22 is connected to the upper arc edge 21. When the ear wing 20 is limited to the concha cavity 42 of the human ear and the upper arc edge 21 bends downward, there is at least one tangent point between the upper arc edge 21 and the helix crus 41.

[0040] The contact surface between the support end 24 of the utility model and the helix foot 41 is an arc surface. When the upper arc edge 21 bends downward, the upper arc edge 21 fits the helix foot 41, the contact area between the ear wing 20 and the helix foot 41 increases, the pressure is reduced, and the pain can be reduced. When the upper arc edge 21 bends upward, the upper arc edge 21 is tightly against the helix foot 41, the limiting effect of the earphone is good, and the earphone is not easy to fall off. The upper arc edge 21 and the helix foot 41 can be completely fitted or partially fitted, that is, there is a tangent point, such as point B or point C.

[0041] Specifically, the ear wing 20 includes a limiting groove 23 , and the earphone is connected to a supporting block 15 , and the supporting block 15 is limited in the limiting groove 23 .

[0042] Specifically, the length from the bottom of the limiting groove 23 to the supporting end 24 is a first length, and the ratio of the length of the supporting block 15 to the first length is 0.35-0.75.

[0043] Specifically, see Figure 4As shown, the earphone is provided with a sound outlet 16, and the length from the support end 24 to the bottom of the limiting groove 23 is a first length (i.e., L1). Through experimental tests, when the ratio of the length of the support block 15 (i.e., L2) to the first length is 0.35-0.75, the supporting effect of the ear wing 20 and the helix foot 41 is better, and the support block 15 is easy to be assembled into the limiting groove 23. When the ratio is less than 0.35, the deformation ability of the ear wing 20 is too strong, the supporting effect of the ear wing 20 and the helix foot 41 is not strong, and the support block 15 is easy to be separated from the limiting groove 23. When the ratio is greater than 0.75, the support block 15 is difficult to be assembled into the limiting groove 23. Of course, it should be noted that in actual applications, the user can adjust the ratio according to actual conditions, and the utility model does not limit this.

[0044] Specifically, see Figures 6 - 8 As shown, the support end 24 and the centroid of the sound outlet 16 of the earphone form a first straight line 50, and the straight line projected outward from the centroid of the sound outlet 16 and perpendicular to the surface of the sound outlet 16 is a second straight line 51 (also the sound normal line), and the first straight line 50 and the second straight line 51 form a first angle θ1, and the first angle θ1 is 0 degrees to 10 degrees.

[0045] Please refer to Figure 9 and Figure 10 In order to better describe the angles in three-dimensional space, a three-dimensional rectangular coordinate system XYZ is established. In the coordinate system, there is an XY plane on the plane where the X direction and the Y direction are located. Similarly, there are also XZ planes and YZ planes. A regular cuboid is placed in the coordinate system. The front and back of the regular cuboid are parallel to the XZ plane, the left and right sides are parallel to the YZ plane, the top and bottom are parallel to the XY plane, and the intersection of the dotted lines on the right side is the centroid of the right side. Starting from the centroid, the projections of the centroid on the YZ plane, XZ plane, and XY plane can be obtained along the X direction, Y direction, and Z direction respectively (not shown in the figure). For easier understanding, for example, a point a is set on the front of the regular cuboid, and the projection of point a along the Y direction to the XZ plane is point a'.

[0046] Please refer to Figure 7 After the above coordinate system is established, the first angle θ1 is the angle formed by the projection of the first straight line 50 and the second straight line 51 along the Y direction toward the XZ plane when the surface of the sound outlet 16 is parallel to the Z direction and the paper direction is parallel to the Y direction. The first angle θ1 on the XZ plane is 0 degrees to 10 degrees.

[0047] Please refer to Figure 8 After the above coordinate system is established, the second angle θ2 is the angle formed by the projection of the first straight line 50 and the second straight line 51 along the Z direction toward the XY plane when the surface of the sound outlet 16 is parallel to the Z direction and the paper direction is parallel to the Z direction. The second angle θ2 on the XY plane is 15 degrees to 45 degrees.

[0048] It should be noted that, after experimental testing, when the first angle θ1 formed by the first straight line 50 and the second straight line 51 of the utility model exceeds 10 degrees, the listening effect is poor, and the support end 24 separates from the thick flesh area at the end of the helix crus 41 and abuts other thin flesh areas, for example, falls into the middle area of ​​the helix crus 41, which is easy to cause pain. When the first angle θ1 formed by the first straight line 50 and the second straight line 51 is in the range of 0 degrees to 10 degrees, the support end 24 falls into the end area of ​​the helix crus 41. At this time, the listening effect is better. The end area of ​​the helix crus 41 is thick and is not easy to cause pain. When the support end 24 of the ear wing 20 is located on the second straight line 51, the first angle is 0 degrees. At this time, the support end 24 falls into the end area of ​​the helix crus 41, which is not easy to cause pain, and the listening effect is best. When the second angle θ2 formed by the first straight line 50 and the second straight line 51 is between 15 and 45 degrees and the support end 24 is located in the concha cavity 42 and abuts against the end area of ​​the helix crus 41 , the sound normal line of the sound outlet 16 can be preferably oriented toward the ear canal.

[0049] The first angle θ1 and the second angle θ2 may be measured in the following manner:

[0050] 1. Magnetic resonance imaging can first make the headphones Figure 7 The sound outlet 16 is fixed, that is, the surface of the sound outlet 16 is parallel to the Z direction, that is, the surface of the sound outlet 16 is vertical, and then the earphone is placed in a nuclear magnetic resonance imaging device for imaging, so that the sound outlet normal line of the earphone is parallel to the X direction in the imaging, and the paper direction is parallel to the Y direction. The centroid of the sound outlet 16 and the supporting end 24 of the ear wing 20 form a first straight line 50, and the first angle θ1 between the normal line and the first straight line 50 on the XZ plane is measured. Similarly, the angle is changed to fix the earphone as follows Figure 8 As shown, the sound normal line of the earphone is parallel to the X direction in the imaging, and the paper direction is parallel to the Z direction. A first straight line 50 is formed by connecting the centroid of the sound outlet 16 and the supporting end 24 of the ear wing 20, and a second angle θ2 between the normal line and the first straight line 50 on the XZ plane is measured.

[0051] 2. Physical angle measurement: First, the earphone shell is opened along the centroid of the sound outlet 16 toward the support end 24 of the ear wing 20, and then connected by the first vertical fixture to form a first straight line 50, and then the normal line of the sound outlet direction is formed by the second vertical fixture. At this time, the angle θ0 between the first vertical fixture and the second vertical fixture can be directly measured, and then the components of the first vertical fixture and the second vertical fixture in the X direction, Y direction, and Z direction can be measured, and then θ1 and θ2 can be obtained through trigonometric function transformation. The first vertical fixture and the second vertical fixture can be opaque materials, such as metal parts, plastic parts, or transparent materials, such as glass parts.

[0052] 3. Based on the actual angle measurement, you can also take photos to measure the earphones. Fix them in the same way as in the MRI method. Figure 7 andFigure 8 Then, take a photo and measure the distances θ1 and θ2 between the first vertical fixture and the second vertical fixture using an image measuring tool.

[0053] Specifically, the earphone fixing structure also includes an earphone sleeve 25, which is connected to the ear wing 20, and the earphone sleeve 25 is mounted on the earphone.

[0054] The earphone sleeve 25 of the present invention also includes a accommodating cavity 27, which is communicated with the limiting groove 23. When the earphone sleeve 25 is mounted on the earphone, the front shell 11 of the earphone body 10 is limited in the accommodating cavity 27, and the support block 15 is connected to the rear shell 12 of the earphone body 10 and limited in the limiting groove 23. The earphone sleeve 25 of the present invention provides pressure to the rear shell 12 close to the front shell 11, thereby enhancing the connection performance of the front shell 11 and the rear shell 12.

[0055] Specifically, the earphone sleeve 25 and the ear wing 20 of the present invention can be made of rubber or other elastic and stretchable materials.

[0056] See also Figure 5 As shown, the utility model designs an earphone, which includes an earphone body 10 and an earphone fixing structure. The earphone body 10 includes a sound outlet 16, and the sound outlet 16 does not enter the ear canal. The sound outlet 16 does not enter the ear canal to avoid the sound outlet 16 from exerting pressure on the inside of the ear canal, thereby avoiding causing pain. The ear wing 20 is fixed to the end area of ​​the helix foot 41, which improves the stability of the earphone fixed in the concha cavity 42, and reduces the possibility of the earphone becoming unstable because the sound outlet 16 does not enter the ear canal.

[0057] The earphone of the present invention can be a wired earphone or a wireless earphone. The earphone also includes an earphone handle 17. When the earphone is a wireless earphone, the earphone handle 17 is embedded in the gap between the tragus 44 and the antitragus 43 to further improve the stability of fixation.

[0058] Specifically, the earphone body 10 includes a front shell 11 and a rear shell 12, and the front shell 11 is clamped with the rear shell 12. The front shell 11 and the rear shell 12 are enclosed to form a storage groove, and the parts of the earphone body 10 are placed in the storage groove. When the parts are damaged, the clamping of the front shell 11 and the rear shell 12 is cancelled, and the parts can be repaired, which is very convenient.

[0059] Specifically, the front shell 11 is further provided with a first pressure relief port 13 , the rear shell 12 is provided with a second pressure relief port 14 , and the earphone fixing structure includes a first pressure relief hole 26 , which is directly opposite to the first pressure relief port 13 .

[0060] When pressure changes occur inside the earphone body 10, the first pressure relief port 13 and the second pressure relief port 14 can release air or replenish air synchronously, keep the air pressure inside the earphone body 10 stable, balance the air pressure inside and outside the earphone body 10, and reduce the risk of sound quality distortion or damage to the earphone body 10 due to the air pressure difference. The first pressure relief port 13 and the first pressure relief hole 26 are directly opposite each other. When releasing air, the air discharged from the first pressure relief port 13 can be directly discharged to the outside through the first pressure relief hole 26. If air needs to be replenished, the outside air can enter the first pressure relief port 13 and the earphone body 10 through the first pressure relief hole 26.

[0061] See also Figure 12 As shown, the utility model also designs an audio device, which includes a neck hanger and earphones. The neck hanger includes a neck hanger part 30 and a control compartment 31. The neck hanger part 30 is fixedly connected to the control compartment 31, and the earphones are electrically connected to the control compartment 31.

[0062] It should be noted that the neck hanging part 30 of the utility model fits the neck, and will not cause discomfort to the user whether walking, exercising or sitting. The earphones are connected to the neck hanging part 30 to effectively prevent the earphones from accidentally falling or being lost. The battery and other components of the earphone body 10 can be placed in the neck hanging part, and the gravity of the earphone body 10 is reduced. The burden of the earphone body 10 on the ear is greatly reduced, which is more suitable for long-term wear. Since the overall mass of the neck-hanging earphone is large, it will generate a large inertia during exercise, causing the earphone to become unstable in the concha cavity 42. The ear wing 20 is fixed to the end area of ​​the helix foot 41, which can provide a better limit effect on the earphone during exercise and improve stability.

[0064] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
