Description

Technical Field

[0001] The present application relates to the technical field of earphones, and more specifically, to an ear cap and an earphone. Background Art

[0002] In-ear headphones are usually fitted with an ear cap, and most of the ear cap designs are centrally symmetrical designs of a body of revolution, and a small number are equiaxially symmetrical designs of an ellipsoid. When these in-ear headphones are inserted into the entrance of the ear canal, the soft ear cap will squeeze the ear canal and make soft contact with the surrounding walls of the ear canal. However, the cross-sectional shape of the human ear canal is asymmetrical. The curvature of the ear canal on the side close to the tragus is relatively straight, and the curvature on the side away from the tragus is relatively curved. When the user inserts the ear cap into the ear canal, the ear canal with a relatively flat curvature will be subjected to greater pressure from the ear cap due to the different amounts of compression in different parts. Users will feel swollen ears after wearing them for a long time, which affects comfort. Summary of the invention

[0003] Embodiments of the present application provide an ear cap and an earphone.

[0004] The present application provides an ear cap. The ear cap includes a first surface, a second surface and a through hole. The first surface and the second surface are arranged opposite to each other, and the through hole penetrates the first surface and the second surface. The ear cap has a plurality of cross sections perpendicular to the extension direction of the through hole, the first surface and the second surface correspond to the two outermost cross sections, the area enclosed by the outer contour of the second surface is larger than the area enclosed by the outer contour of the first surface, the outer contour of each cross section includes a first area, a second area, a third area, and a fourth area connected end to end, and the radius of curvature of the first area is larger than the radius of curvature of the third area.

[0005] The present application provides an earphone. The earphone includes an earphone body and an ear cap. The earphone body includes a connecting portion. The ear cap includes a first surface, a second surface and a through hole. The first surface and the second surface are arranged opposite to each other, and the through hole penetrates the first surface and the second surface. The ear cap has a plurality of cross sections perpendicular to the extension direction of the through hole, the first surface and the second surface correspond to the two outermost cross sections, the area enclosed by the outer contour of the second surface is larger than the area enclosed by the outer contour of the first surface, and the outer contour of each cross section includes a first area, a second area, a third area, and a fourth area connected end to end, and the radius of curvature of the first area is larger than the radius of curvature of the third area. The connecting portion of the earphone body is passed through the through hole.

[0006] The ear cap and earphone of the present application adopt an asymmetric structure in which the radius of curvature of the first area of ​​the ear cap cross section is larger than the radius of curvature of the third area. This allows the ear cap to fit the user's ear canal more closely and allows the force around the ear canal to be evenly distributed after wearing, thereby avoiding the feeling of swollen ears caused by wearing the ear cap for a long time, thereby improving the wearing comfort of the ear cap.

[0016] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. The same or similar reference numerals in the accompanying drawings represent the same or similar elements or elements with the same or similar functions.

[0017] In addition, the embodiments of the present application described below in conjunction with the drawings are exemplary and are only used to explain the embodiments of the present application and should not be construed as limiting the present application.

[0018] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0019] Figure 1 The cross-sectional view of a human ear is shown in the figure, where the ear canal 401 includes a first side surface 403 and a second side surface 404, and the first side surface 403 is closer to the tragus 402 than the second side surface 404. The ear canal 401 has a relatively straight arc on the side close to the tragus 402 and a relatively curved arc on the side away from the tragus 402. That is, the first side surface 403 is relatively straighter than the second side surface 404.

[0020] Most ear cap designs are designed with central symmetry of a body of revolution, and a small number are designed with ellipsoidal equiaxial symmetry. This type of design is convenient for production and assembly. However, the cross-sectional shape of the human ear canal is asymmetrical. When a user wears an ear cap with a symmetrical design, the compression amount of different parts is different. In order to ensure sealing, the design of the ear cap will consider the area with a larger curvature on the side of the ear canal. After symmetry, the ear canal with a flatter curvature will be subjected to greater pressure from the ear cap. Users will feel swollen ears when wearing this type of symmetrical ear cap for a long time, which affects the user's comfort.

[0021] See also Figure 2 and Figure 3 The present application provides an ear cap 100. The ear cap 100 includes a first surface 10 and a second surface 20 that are arranged opposite to each other. The ear cap 100 is provided with a through hole 30 that penetrates the first surface 10 and the second surface 20. The ear cap 100 has a plurality of cross sections perpendicular to the extension direction of the through hole 30, the first surface 10 and the second surface 20 correspond to the two outermost cross sections, the area enclosed by the outer contour of the second surface 20 is larger than the area enclosed by the outer contour of the first surface 10, the outer contour of each cross section includes a first area 41, a second area 42, a third area 43, and a fourth area 44 that are connected end to end, and the curvature radius of the first area 41 is larger than the curvature radius of the third area 43.

[0022] The ear cap 100 of the present application adopts an asymmetric structure in which the curvature radius of the first area 41 of the cross section of the ear cap 100 is greater than the curvature radius of the third area 43, so that the ear cap 100 can fit into the ear canal 401 (eg, Figure 1The ear cap 100 is more fitted and can evenly distribute force around the ear canal 401 after wearing, thereby preventing the user from feeling swollen ears due to wearing the ear cap 100 for a long time, thereby improving the wearing comfort of the ear cap 100.

[0023] Further description will be given below in conjunction with the accompanying drawings.

[0024] See also Figure 1 , Figure 2 and Figure 3 The ear cap 100 includes a first surface 10, a second surface 20 and a through hole 30. The first surface 10 and the second surface 20 are arranged opposite to each other. The through hole 30 penetrates the first surface 10 and the second surface 20. The ear cap 100 has a plurality of cross sections perpendicular to the extension direction of the through hole 30, and the first surface 10 and the second surface 20 correspond to the two outermost cross sections. Among them, the area enclosed by the outer contour of the second surface 20 is larger than the area enclosed by the outer contour of the first surface 10.

[0025] It should be noted that when the user wears the ear cap 100, that is, when inserting the ear cap 100 into the ear canal 401, the user inserts the first surface 10 into the deeper part of the ear canal 401 for wearing. In all embodiments of the present application, the user wears the ear cap 100 in this way, which will not be described in detail below. Since the area enclosed by the outer contour of the first surface 10 is smaller than the area enclosed by the outer contour of the second surface 20, on the one hand, the first surface 10 is easier to insert into the ear canal 401, and on the other hand, the structure of the ear cap 100 with one end larger and the other end smaller is more in line with the shape of the ear canal 401, which can make the ear cap 100 not only tightly inserted into the ear canal 401 but also not easily fall off from the ear canal 401 to the outside, but also avoid the feeling of being squeezed and swollen.

[0026] In some embodiments, the area enclosed by the outer contour of each cross section has different sizes, and the areas enclosed by the outer contours of the multiple cross sections decrease in sequence along the direction from the second surface 20 to the first surface 10. In other words, the areas enclosed by the outer contours of the multiple cross sections have different sizes, and the closer the cross section is to the second surface 20, the larger the area enclosed by its outer contour; the closer the cross section is to the first surface 10, the smaller the area enclosed by its outer contour. Since the areas enclosed by the outer contours of the multiple cross sections decrease in sequence along the direction from the second surface 20 to the first surface 10, the shape of the ear cap 100 is more consistent with the shape of the user's ear canal 401, so that the ear cap 100 can fit the user's ear canal 401 more closely, and the ear cap 100 is not likely to fall off from the ear canal 401.

[0027] Figure 3 The figure shows the outer contour of one cross section of the ear cap 100. Figure 3, the outer contour of each cross section includes a first area 41, a second area 42, a third area 43 and a fourth area 44 which are connected end to end in sequence. The radius of curvature of the first area 41 is greater than the radius of curvature of the third area 43. The larger the radius of curvature, the flatter the area. In other words, the first area 41 is flatter than the third area 43.

[0028] It should be noted that if Figure 1 As shown, the cross-sectional shape of the human ear canal 401 is asymmetric. The curvature of the ear canal 401 on the side close to the tragus 402 is relatively straight, and the curvature on the side away from the tragus 402 is relatively curved, that is, the first side 403 of the ear canal 401 is straighter than the second side 404 of the ear canal 401. When the user wears the ear cap 100, that is, when the ear cap 100 is inserted into the ear canal 401, the first area 41 of the ear cap 100 is close to the side of the tragus 402, and the third area 43 of the ear cap 100 is worn away from the side of the tragus 402, that is, the first area 41 of the ear cap 100 is close to the first side 403 of the ear canal 401, the third area 43 of the ear cap 100 is close to the second side 404 of the ear canal 401, and the fourth area 44 of the ear cap 100 is closer to the earlobe than the second area 42. In all embodiments of the present application, the user wears the ear cap 100 in this way, which will not be repeated below. Since the curvature radius of the first area 41 of the ear cap 100 close to the user's tragus 401 is larger than the curvature radius of the third area 43 away from the tragus 402, that is, the area of ​​the ear cap 100 close to the user's tragus 402 is flatter than the area of ​​the ear cap 100 away from the tragus 401. On the one hand, the shape of the ear cap 100 is more consistent with the shape of the user's ear canal 401, so that the ear cap 100 is not easy to fall out of the ear canal 401; on the other hand. Since the area of ​​the ear cap 100 close to the tragus 402 is flatter, the ear canal 401 after wearing the ear cap 100 can be evenly stressed, thereby improving the user's wearing experience and increasing the comfort of wearing the ear cap 100.

[0029] See also Figure 1 and Figure 3, the radius of curvature of the first area 41 is greater than or equal to 6.5 mm, that is, the radius of curvature of the first area 41 is not less than 6.5 mm. For example, the radius of curvature of the first area 41 can be any one of 6.5 mm, 6.85 mm, 8.5 mm, 10 mm, 12 mm, 18 mm, 25 mm, 29.2 mm, 30 mm, 45.5 mm, 56.9 mm, 100 mm, 150 mm, 180 mm, or any value between any adjacent values. If the radius of curvature of the first area 41 is too small (for example, less than 6.5 mm), the first area 41 of the ear cap 100 will continuously squeeze the ear canal, causing the user to feel swollen ears after wearing the ear cap 100 for a long time. In the embodiment of the present application, the radius of curvature of the first area 41 is greater than or equal to 6.5 mm, so that when the user wears the ear cap 100, the first area 41 of the ear cap 100 can fit well with the user's ear canal 401 on the side of the tragus 402, that is, the first area 41 of the ear cap 100 can fit well with the first side surface 403 of the user's ear canal 401, while preventing the ear cap 100 from falling off the ear canal, it can reduce the pressure of the ear cap 100 on the user's ear canal 401 on the side of the tragus 402, thereby improving the wearing comfort of the ear cap 100.

[0030] The radius of curvature of the third region 43 is less than or equal to 20 mm, that is, the radius of curvature of the third region 43 is not greater than 20 mm. For example, the radius of curvature of the third region 43 can be any one of 0 mm, 0.5 mm, 0.86 mm, 1.3 mm, 2.67 mm, 3 mm, 5.2 mm, 9 mm, 12.5 mm, 15 mm, 17 mm, 18.6 mm, or 20 mm, or any value between any adjacent values. If the radius of curvature of the third region 43 is too large (for example, greater than 20 mm), the third region 43 is flatter than the ear canal on the side of the concha cavity. At this time, there is a gap between the third region 43 of the ear cap 100 and the ear canal 401, which is not conducive to the sealing of the ear cap 100. Noise will enter the human ear from the gap between the third region 43 of the ear cap 100 and the ear canal 401, reducing the noise reduction performance of the ear cap 100. In the embodiment of the present application, the radius of curvature of the third area 43 is less than or equal to 20 mm, so that when the user wears the ear cap 100, the third area 43 of the ear cap 100 can better fit with the side of the user's ear canal 401 away from the tragus 402, that is, the third area 43 of the ear cap 100 can better fit with the second side surface 404 of the user's ear canal 401, which can not only prevent the ear cap 100 from falling off the ear canal 401, but also improve the noise reduction performance of the ear cap 100.

[0031] It should be noted that, in some embodiments, the ear cap 100 needs to satisfy that the radius of curvature of the first area 41 is greater than or equal to 6.5 mm; or, the ear cap 100 needs to satisfy that the radius of curvature of the third area 43 is less than or equal to 20 mm; or, the ear cap 100 needs to satisfy that the radius of curvature of the first area 41 is greater than or equal to 6.5 mm, and the radius of curvature of the third area 43 is less than or equal to 20 mm. There is no limitation here, and it only needs to satisfy that the radius of curvature of the first area 41 is greater than the radius of curvature of the third area 43. Both of these can improve the uniformity of force on the ear canal 401 after wearing the ear cap 100.

[0032] See also Figure 1 and Figure 4 In some embodiments, the taper angle α of the ear cap 100 is in the range of [0.5°, 178°]. For example, the taper angle α can be any one of 0.5°, 2.5°, 5°, 15.2°, 30°50.5°, 78°, 100°, 120.5°, 150°, 165°, 178°, or any value between any adjacent values. Specifically, the side surface where the multiple first areas 41 of the ear cap 100 are located extends from the second surface 20 to the first surface 10, and the side surface where the multiple third areas 43 are located extends from the second surface 20 to the first surface 10, and the angle of the cone section of the cone after the two extended surfaces intersect is the taper angle α. When the vertical distance between the first surface 10 and the second surface 20 is constant, if the taper angle α is too small (for example, less than 0.5°), the volume of the ear cap 100 will be too small and cannot completely fill the user's ear canal 401. In other words, there will be a gap between the ear cap 100 and the inner wall of the ear canal 401. This increases the possibility of the ear cap 100 shaking in the ear canal 401, thereby reducing the comfort of the user. If the taper angle α is too large (for example, greater than 178°), the volume of the ear cap 100 will be too large, and the ear cap 100 will continuously squeeze the inner wall of the ear canal 401, exerting pressure on the inner wall of the ear canal 401, causing the user to feel swollen ears after wearing the ear cap 100 for a long time. In the embodiment of the present application, the range of the taper angle α is within [0.5°, 178°], which can not only prevent the ear cap 100 from shaking in the ear canal 401, but also reduce the squeezing of the ear canal 401 by the ear cap 100, thereby improving the wearing comfort of the ear cap 100.

[0033] See also Figure 1 and Figure 3In some implementation examples, the radius of curvature of the second area 42 is less than or equal to 10 mm and greater than or equal to 1.5 mm. For example, the radius of curvature of the second area 42 can be any one of 1.5 mm, 1.75 mm, 2 mm, 2.8 mm, 3.8 mm, 4.5 mm, 5.62 mm, 6.7 mm, 8 mm, 9 mm, 10 mm or any value between any adjacent values. If the radius of curvature of the second area 42 is too small (e.g., less than 1.5 mm), there is a gap between the second area 42 and the ear canal 401, and noise will enter the human ear from the gap between the second area 42 of the ear cap 100 and the ear canal 401; if the radius of curvature of the second area 42 is too large (e.g., greater than 10 mm), the ear cap 100 will continuously squeeze the ear canal 401, causing discomfort to the user. In the embodiment of the present application, since the radius of curvature of the second area 42 is less than or equal to 10 mm and greater than or equal to 1.5 mm, it can not only reduce the pressure applied by the ear cap 100 to the ear canal 401 to improve the wearing comfort of the ear cap 100, but also increase the sealing of the ear cap 100 to reduce the environmental noise from entering the human ear.

[0034] Similarly, in some embodiments, the radius of curvature of the fourth region 44 is less than or equal to 10 mm and greater than or equal to 1.5 mm. For example, the radius of curvature of the fourth region 44 can be any one of 1.5 mm, 1.95 mm, 2.3 mm, 3.5 mm, 4.8 mm, 5.5 mm, 6.3 mm, 7.2 mm, 8 mm, 9.2 mm, 10 mm, or any value between any adjacent values. If the radius of curvature of the fourth region 44 is too small (e.g., less than 1.5 mm), there is a gap between the fourth region 44 and the ear canal 401, and noise will enter the human ear from the gap between the fourth region 44 of the ear cap 100 and the ear canal 401; if the radius of curvature of the fourth region 44 is too large (e.g., greater than 10 mm), the ear cap 100 will continuously squeeze the ear canal 401, causing discomfort to the user. In the embodiment of the present application, since the radius of curvature of the fourth area 44 is less than or equal to 10 mm and greater than or equal to 1.5 mm, it can not only reduce the pressure applied by the ear cap 100 to the ear canal 401 to improve the wearing comfort of the ear cap 100, but also increase the sealing of the ear cap 100 to reduce the environmental noise from entering the human ear.

[0035] Of course, in some embodiments, the ear cap 100 simultaneously satisfies the curvature radius of the second region 42 being less than or equal to 10 mm and greater than or equal to 1.5 mm, and the curvature radius of the fourth region 44 being less than or equal to 10 mm and greater than or equal to 1.5 mm. In this way, the shape of the ear cap 100 is more consistent with the shape of the user's ear canal 401, so that the ear cap 100 can fit the user's ear canal 401 more closely, and the ear cap 100 is not likely to fall off from the ear canal 401.

[0036] In some embodiments, the radius of curvature of the second area 42 is greater than the radius of curvature of the fourth area 44. In this way, the shape of the ear cap 100 fits the ear canal 401 more closely, so that the ear cap 100 can better fit the ear canal 401, thereby making it difficult for the ear cap 100 to fall off the ear canal and increasing the comfort of the user wearing the ear cap 100.

[0037] See also Figure 1 and Figure 3 , in any cross section, there is a first distance L between the tangent line of the highest point of the first area 41 and the tangent line of the highest point of the third area 43; there is a second distance H between the tangent line of the highest point of the second area 42 and the tangent line of the highest point of the fourth area 44, and the first distance L is smaller than the second distance H. In this way, the outer contours of multiple cross sections of the ear cap 100 in the extending direction of the vertical through hole 30 are similar to the cross-sectional shape of the user's ear canal 401, so that when the user wears the ear cap 100, the ear cap 100 can fit the ear canal 401 more closely, and the ear cap 100 can be prevented from falling off.

[0038] Specifically, in some embodiments, the value range of the first distance L is [3.5mm, 16mm], for example, the first distance L can be any one of 3.5mm, 3.7mm, 4mm, 5.8mm, 7mm, 8.5mm, 9.2mm, 10mm, 11.5mm, 12mm, 14mm, 15.25mm, 15.8mm, 16mm or any value between any adjacent values; the value range of the second distance H is [5mm, 20mm], for example, the second distance H can be any one of 5mm, 6.8mm, 7mm, 8.2mm, 10mm, 11.2mm, 12.89mm, 14mm, 15.5mm, 16mm, 18.2mm, 19mm, 20mm or any value between any adjacent values. If the first distance L is too small (for example, less than 3.5 mm), or the second distance H is too small (for example, less than 5 mm), when the user wears the ear cap 100, there is a gap between the ear cap 100 and the ear canal 401, and the ear cap 100 is easy to detach from the ear canal 401, and noise is also easy to enter the human ear from the gap between the ear cap 100 and the ear canal 401; if the first distance L is too large (for example, greater than 16 mm), or the second distance H is too large (for example, greater than 20 mm), when the user wears the ear cap 100, the ear cap 100 will continuously squeeze the ear canal 401, causing the user's ears to feel sore and swollen, affecting the user experience. In the embodiment of the present application, since the value range of the first distance L is [3.5 mm, 16 mm], the value range of the second distance H is [5 mm, 20 mm], and the first distance L is smaller than the second distance H, the ear cap 100 fits the ear canal 401 more closely, and the gap between the ear cap 100 and the ear canal 401 is reduced, thereby preventing the ear cap 100 from falling off and reducing the noise entering the human ear, thereby improving the noise reduction performance of the ear cap 100. In addition, the squeezing force of the ear cap 100 on the ear canal 401 can also be reduced, and the pressure of the ear cap 100 on the human ear is reduced, thereby greatly improving the comfort of the user wearing the ear cap 100.

[0039] The ear cap 100 may be made of a soft material. For example, in some embodiments, the ear cap 100 may be made of polyurethane foam. Figure 5, the ear cap 100 is made of polyurethane foam, and the area between the first surface 10 and the second surface 20 of the ear cap 100, except for the through hole 30, is filled with polyurethane foam. That is to say, the area of ​​the ear cap 100 except for the through hole 30 is a solid structure. Since the polyurethane foam is soft and has a certain sealing property, it can improve the comfort of the ear cap 100 after wearing while improving the noise reduction performance of the ear cap 100. Of course, the ear cap 100 can also be made of a flexible sealing material that can directly contact the skin, which is not limited here. For example, in some embodiments, the ear cap 100 can be made of silicone rubber, and the hardness range of the ear cap 100 is within [0HA, 140HA]. For details, please refer to Figure 6 The ear cap 100 is made of silicone rubber with a hardness range of [0HA, 140HA]. The through hole 30 of the ear cap 100 is a stepped hole, and the through hole 30 includes a first sub-hole 31 and a second sub-hole 32. The first sub-hole 31 and the second sub-hole 32 are arranged in sequence along the direction from the first surface 10 to the second surface 20, that is, the first sub-hole 31 is closer to the first surface 10 than the second sub-hole 32, and the opening size of the first sub-hole 31 is smaller than the opening size of the second sub-hole 32, so as to form a stepped surface 33 at the junction of the first sub-hole 31 and the second sub-hole 32. The ear cap 100 also includes a conduit 50, which extends from the stepped surface 33 into the second sub-hole 32. The conduit 50 is arranged in the second sub-hole 32 and surrounds the first sub-hole 31. Since the silicone rubber with a hardness range of [0HA, 140HA] is soft, the comfort of wearing the ear cap 100 is improved, and the user experience is enhanced. Of course, the ear cap 100 can also be made of other flexible materials, which is not limited here.

[0040] See also Figure 7 The present application further provides an earphone 300 . The earphone 300 includes an earphone body 200 and an ear cap 100 in any one of the above embodiments. The earphone body 200 includes a connecting portion 201 , and the connecting portion 201 is installed in the through hole 30 .

[0041] The earphone 300 of the present application adopts an asymmetric structure in which the curvature radius of the first area 41 of the ear cap 100 is greater than the curvature radius of the third area 43, so that the ear cap 100 can fit the ear canal of the user more closely, and the ear canal 401 ( Figure 1 The force around the ear cap 100 is uniform, which prevents the user from feeling swollen ears due to wearing the ear cap 100 for a long time, thereby improving the wearing comfort of the ear cap 100.

[0042] Specifically, in some embodiments, the earphone body 200 and the ear cap 100 are fixedly connected. For example, an interference fit is adopted between the connecting portion 201 of the earphone body 200 and the through hole 30, so that the connecting portion 201 is fixed in the through hole 30. Since the earphone body 200 and the ear cap 100 are fixedly connected, the ear cap 100 can be prevented from falling off from the earphone body 200, thereby extending the service life of the earphone 300. Specifically, the connecting portion 201 and the through hole 30 can be connected by gluing, which is not limited here.

[0043] In other embodiments, the earphone body 200 and the ear cap 100 are detachably connected. For example, the connection portion and the through hole 30 are connected by snap-fitting or threading. Since the earphone body 200 and the ear cap 100 are detachable, when the ear cap 100 is damaged, only the ear cap 100 needs to be replaced without replacing the entire earphone 300, which saves costs.

[0044] It should be noted that in some embodiments, the connection portion 201 is solid and sealed. That is, sound cannot be transmitted in the connection portion 201. In this case, the earphone 300 can fit the user's ear canal more closely and prevent external sound from being transmitted to the human ear, thereby achieving a noise reduction function. Figure 7 In some embodiments, the connecting portion 201 is a hollow structure, and the connecting portion 201 includes a sound outlet 2011, which is arranged on a side of the connecting portion 201 close to the first surface 10 of the ear cap 100, so that the sound played in the earphone 300 can be transmitted in the connecting portion 201 and transmitted to the human ear through the sound outlet 2011.
