Technical Field

The application relates to the technical field of earphones, in particular to an earcap and an earphone.

Background

An earcap is generally sleeved on the in-ear earphone, the majority of earcaps are designed in a revolving body type centrosymmetric mode, and the minority of earcaps are designed in an ellipsoid equiaxial symmetric mode. When these in-ear earphones are inserted into the entrance of the ear canal of the ear, the soft earcap presses the ear canal and makes soft contact with the peripheral wall of the ear canal. However, the cross-sectional shape of the human ear canal is asymmetrical, with the canal being relatively flat on the side near the tragus and relatively curved on the side away from the tragus. When a user plugs the earcap into the ear canal, the compression amount of different parts is different, so that the earcap pressure on the ear canal with the radian bending being relatively flat is large. The user can feel expanded when wearing the shoe for a long time, which affects the comfort.

In addition, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the present application.

In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through intervening media. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Fig. 1 is a cross-sectional view of a human ear, as shown, ear canal 401 includes a first side 403 and a second side 404, with first side 403 being closer to tragus 402 than second side 404. And the ear canal 401 is relatively flat at the side near the tragus 402 and relatively curved at the side away from the tragus 402. I.e., the first side 403 is more straight than the second side 404.

Most of the ear caps are designed in a center symmetry mode like a revolving body, and a small part of the ear caps are designed in an equiaxial symmetry mode like an ellipsoid. Such a design facilitates production and assembly. But the cross-sectional shape of the human ear canal is asymmetrical. When the user wears the symmetrically designed earcap, the amount of compression is different at different locations. In order to ensure sealing, the design of the ear cap considers the area with relatively large radian bending of the side surface of the auditory canal, and after symmetry, the ear cap pressure on the auditory canal with relatively flat radian bending is large. When a user wears the ear cap with the symmetrical structure for a long time, the user can feel expanded, and the comfort of the user is affected.

Referring to fig. 2 and 3, an ear cap 100 is provided. The ear cap 100 includes a first surface 10 and a second surface 20 disposed opposite to each other. The ear cap 100 is formed with a through hole 30 penetrating the first surface 10 and the second surface 20. The ear cap 100 has a plurality of cross sections perpendicular to the extending direction of the through hole 30, the first surface 10 and the second surface 20 correspond to 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 comprises a first area 41, a second area 42, a third area 43 and a fourth area 44 which are connected end to end, and the curvature radius of the first area 41 is larger than that of the third area 43.

The ear cap 100 of the present application, by adopting the asymmetric structure that the curvature radius of the first region 41 of the cross section of the ear cap 100 is larger than the curvature radius of the third region 43, the ear cap 100 can be more attached to the ear canal 401 (as shown in fig. 1) of the user, and the stress around the ear canal 401 after being worn can be uniform, thereby avoiding the user from wearing the ear cap 100 for a long time and generating the feeling of ear expansion, and further improving the wearing comfort of the ear cap 100.

The following is further described with reference to the accompanying drawings.

Referring to fig. 1, 2 and 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 disposed opposite to each other. The through hole 30 penetrates through the first surface 10 and the second surface 20. The ear cap 100 has a plurality of cross sections perpendicular to the extending direction of the through hole 30, and the first surface 10 and the second surface 20 correspond to the outermost two cross sections. Wherein, 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.

It should be noted that, when the user wears the ear cap 100, that is, when the ear cap 100 is inserted into the ear canal 401, the user inserts the first surface 10 into a position closer to the deep part of the ear canal 401 for wearing, and in all embodiments of the present application, the user wears the ear cap 100 as such, which will not be described in detail later. Because the area that the outline of first surface 10 encloses is less than the area that the outline of second surface 20 encloses, on the one hand first surface 10 fills in the duct 401 more easily, and on the other hand, the structure that the big end of ear cap 100 one end is little more accords with the shape of duct 401, can make ear cap 100 can tightly fill in the duct 401 and be difficult to drop to the external world from the duct 401 in, the crowded sensation of production that can also avoid.

In some embodiments, the areas enclosed by the outer contours of each cross-section have different sizes, and the areas enclosed by the outer contours of the plurality of cross-sections decrease sequentially along the direction from the second surface 20 to the first surface 10. That is, the areas enclosed by the outer contours of the plurality of sections have different sizes, and the area enclosed by the outer contours is larger the closer to the section of the second surface 20; the closer to the cross-section of the first surface 10, the smaller the area enclosed by its outer contour. Because the area enclosed by the outer contours of the plurality of cross sections is sequentially reduced along the direction from the second surface 20 to the first surface 10, the shape of the ear cap 100 is more suitable for the shape of the ear canal 401 of the user, so that the ear cap 100 can be more suitable for the ear canal 401 of the user, and the ear cap 100 is not easy to fall off from the ear canal 401.

Fig. 3 is a schematic diagram showing an outer contour of one of the cross sections of the ear cap 100, and referring to fig. 3, the outer contour of each cross section includes a first region 41, a second region 42, a third region 43 and a fourth region 44 which are connected end to end in sequence. The radius of curvature of the first region 41 is greater than the radius of curvature of the third region 43. A larger radius of curvature indicates a flatter area. That is, the first region 41 is flatter than the third region 43.

As shown in fig. 1, the cross-sectional shape of the human ear canal 401 is asymmetrical. The curvature of the ear canal 401 is relatively flat on the side near the tragus 402 and relatively curved on the side away from the tragus 402, i.e. the first side 403 of the ear canal 401 is relatively flat compared to 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 region 41 of the ear cap 100 is close to the tragus 402 side, and the third region 43 of the ear cap 100 is away from the tragus 402 side for wearing, that is, the first region 41 of the ear cap 100 is close to the first side 403 of the ear canal 401, the third region 43 of the ear cap 100 is close to the second side 404 of the ear canal 401, and the fourth region 44 of the ear cap 100 is closer to the ear lobe than the second region 42. Since the radius of curvature of the first region 41 of the ear cap 100 on the side close to the tragus 401 of the user is larger than the radius of curvature of the third region 43 on the side remote from the tragus 402, the region of the ear cap 100 on the side close to the tragus 402 of the user is flatter than the region of the ear cap 100 on the side remote from the tragus 401. On one hand, the shape of the ear cap 100 is more suitable for the shape of the ear canal 401 of the user, so that the ear cap 100 is not easy to be separated from the ear canal 401; in another aspect. Because the area of the ear cap 100 near the tragus 402 is more straight, the ear canal 401 after wearing the ear cap 100 is stressed uniformly, so that the wearing experience of a user can be improved, and the wearing comfort of the ear cap 100 is improved.

Referring to fig. 1 and 3, the radius of curvature of the first region 41 is greater than or equal to 6.5mm, i.e., the radius of curvature of the first region 41 is not less than 6.5 mm. For example, the radius of curvature of the first region 41 may be any one of 6.5mm, 6.85mm, 8.5mm, 10mm, 12mm, 18mm, 25mm, 29.2mm, 30mm, 45.5mm, 56.9mm, 100mm, 150mm, 180mm or any value between any adjacent values. If the radius of curvature of the first region 41 is too small (e.g., less than 6.5mm), the first region 41 of the ear cap 100 will be pressed against the ear canal, causing a feeling of ear fullness to the user when wearing the ear cap 100 for a long period of time. In the embodiment of the present application, the radius of curvature of the first region 41 is greater than or equal to 6.5mm, when the user wears the earcap 100, the first region 41 of the earcap 100 can be well attached to one side of the tragus 402 of the user by the ear canal 401, that is, the first region 41 of the earcap 100 can be well attached to the first side 403 of the ear canal 401 of the user, so that the earcap 100 is prevented from falling off from the ear canal, and meanwhile, the pressure of the earcap 100 on one side of the tragus 402 of the user by the ear canal 401 can be reduced, thereby improving the wearing comfort of the earcap 100.

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

It is noted that in some embodiments, the ear cap 100 can be configured such that the radius of curvature of the first region 41 is greater than or equal to 6.5 mm; alternatively, the ear cap 100 can be such that the third region 43 has a radius of curvature of less than or equal to 20 mm; or, the ear cap 100 needs to satisfy the requirement that the radius of curvature of the first region 41 is greater than or equal to 6.5mm and the radius of curvature of the third region 43 is less than or equal to 20mm at the same time, which is not limited herein, and only needs to satisfy the requirement that the radius of curvature of the first region 41 is greater than the radius of curvature of the third region 43, so that the degree of uniformity of stress of the ear canal 401 after wearing the ear cap 100 can be improved.

Referring to fig. 1 and 4, in some embodiments, the ear cap 100 has a taper angle α in the range of [0.5 °, 178 °. For example, the taper angle α may 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 plurality of first regions 41 of the ear cap 100 extend from the second surface 20 to the first surface 10, the plurality of third regions 43 extend from the second surface 20 to the first surface 10, and the included angle of the taper section of the taper after the intersection of the two extending surfaces is the taper angle α. With a certain perpendicular distance between the first surface 10 and the second surface 20, if the taper angle α is too small (e.g., less than 0.5 °), the volume of the ear cap 100 will be too small to completely fill the ear canal 401 of the user. That is, a gap is formed between the earcap 100 and the inner wall of the ear canal 401. As such, the likelihood of the earcap 100 rattling in the ear canal 401 is increased, thereby reducing user comfort. If the taper angle α is too large (e.g., greater than 178 °), the volume of the ear cap 100 will be too large, and the ear cap 100 will continuously press against the inner wall of the ear canal 401 to apply pressure to the inner wall of the ear canal 401, resulting in a feeling of ear expansion when the user wears 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 not only can prevent the earcap 100 from shaking in the ear canal 401, but also can slow down the extrusion of the earcap 100 on the ear canal 401, thereby improving the wearing comfort of the earcap 100.

Referring to fig. 1 and 3, in some embodiments, the radius of curvature of the second region 42 is less than or equal to 10mm and greater than or equal to 1.5 mm. For example, the radius of curvature of the second region 42 may be any one of 1.5mm, 1.75mm, 2mm, 2.8mm, 3.8mm, 4.5mm, 5.62mm, 6.7mm, 8mm, 9mm, 10mm or any value between any adjacent values. If the radius of curvature of the second region 42 is too small (e.g., less than 1.5mm), there is a gap between the second region 42 and the ear canal 401, and noise can enter the human ear from the gap between the second region 42 of the ear cap 100 and the ear canal 401; if the radius of curvature of the second region 42 is too large (e.g., greater than 10mm), the ear cap 100 will be continually compressed against the ear canal 401, causing an uncomfortable sensation to the user. In the embodiment of the present application, since the radius of curvature of the second region 42 is less than or equal to 10mm and greater than or equal to 1.5mm, it is able to both reduce the pressure applied by the earcap 100 to the ear canal 401 to improve the wearing comfort of the earcap 100 and increase the sealing performance of the earcap 100 to reduce the environmental noise entering into the human ear.

Likewise, in some embodiments, the radius of curvature of the fourth region 44 is less than or equal to 10mm and greater than or equal to 1.5 mm. For example, the radius of curvature of the fourth region 44 may be any one of 1.5mm, 1.95mm, 2.3mm, 3.5mm, 4.8mm, 5.5mm, 6.3mm, 7.2mm, 8mm, 9.2mm, 10mm or any value between any adjacent values. If the radius of curvature of the fourth region 44 is too small (e.g., less than 1.5mm), there is a gap between the fourth region 44 and the ear canal 401, and noise can 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 10mm), the ear cap 100 will be continually compressed against the ear canal 401, causing an uncomfortable sensation to the user. In the embodiment of the present application, since the radius of curvature of the fourth region 44 is less than or equal to 10mm and greater than or equal to 1.5mm, it is able to both reduce the pressure applied by the earcap 100 to the ear canal 401 to improve the wearing comfort of the earcap 100 and increase the sealing performance of the earcap 100 to reduce the environmental noise entering into the human ear.

Of course, in some embodiments, the ear cap 100 satisfies both a radius of curvature of the second region 42 of less than or equal to 10mm and greater than or equal to 1.5mm, and a radius of curvature of the fourth region 44 of less than or equal to 10mm and greater than or equal to 1.5 mm. Thus, the shape of the ear cap 100 is more suitable for the shape of the ear canal 401 of the user, so that the ear cap 100 can be more suitable for the ear canal 401 of the user, and the ear cap 100 is not easy to fall off from the ear canal 401.

In some embodiments, the radius of curvature of the second region 42 is greater than the radius of curvature of the fourth region 44. So, the shape of ear cap 100 is more laminated with the auditory canal 401, can make ear cap 100 and the cooperation of auditory canal 401 better to when making ear cap 100 be difficult to drop from the auditory canal, increase the comfort that the user wore ear cap 100.

Referring to fig. 1 and fig. 3, in any cross section, a first distance L is formed between a tangent line at the highest point of the first region 41 and a tangent line at the highest point of the third region 43; a second distance H is provided between a tangent to the highest point of the second region 42 and a tangent to the highest point of the fourth region 44, and the first distance L is smaller than the second distance H. In this way, the shapes of the outer contours of the plurality of cross sections of the earcap 100 perpendicular to the extending direction of the through hole 30 are similar to the cross sectional shape of the ear canal 401 of the user, so that the earcap 100 can be more closely attached to the ear canal 401 when the user wears the earcap 100, and the earcap 100 is prevented from falling off.

Specifically, in some embodiments, the first distance L has a value in a range of [3.5mm, 16mm ], for example, the first distance L may 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 second distance H may be in a range of [5mm, 20mm ], for example, the second distance H may 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 (e.g., less than 3.5mm), or the second distance H is too small (e.g., less than 5mm), when the user wears the earcap 100, there is a gap between the earcap 100 and the ear canal 401, the earcap 100 is easily detached from the ear canal 401, and noise is also easily introduced into the human ear from the gap between the earcap 100 and the ear canal 401; if the first distance L is too large (e.g., greater than 16mm) or the second distance H is too large (e.g., greater than 20mm), the ear cap 100 may continuously squeeze the ear canal 401 when the user wears the ear cap 100, which may cause the user's ear to feel sour and affect the user experience. This application embodiment is because the value range of first distance L is [3.5mm, 16mm ], the value range of second distance H is [5mm, 20mm ], and first distance L is less than second distance H, therefore, earcap 100 more laminates with duct 401, the clearance between earcap 100 and duct 401 reduces, thereby when avoiding earcap 100 to drop, can reduce the noise and get into people's ear, promote the performance of making an uproar of earcap 100. In addition, the pressing force of the earcap 100 against the ear canal 401 can be reduced, and the pressure of the earcap 100 against the human ear can be reduced, so that the comfort of the user wearing the earcap 100 can be greatly improved.

The ear cap 100 can be made of a soft material. For example, in some embodiments, the ear cap 100 can be made of polyurethane foam. Specifically, referring to fig. 5, the ear cap 100 is made of polyurethane foam, and polyurethane foam is filled between the first surface 10 and the second surface 20 of the ear cap 100 except for the through hole 30. That is, the ear cap 100 is of a solid construction except for the region in which the through-hole 30 is formed. Since the polyurethane foam is soft and has a certain sealing property, the noise reduction performance of the earcap 100 can be improved while the comfort of the earcap 100 after wearing is improved. Of course, the ear cap 100 can also be made of a flexible sealing material that can directly contact the skin, and is not limited thereto. For example, in some embodiments, ear cap 100 can be made of silicone rubber, and ear cap 100 HAs a hardness in the range of [0HA, 140HA ]. Specifically, referring to fig. 6, the earcap 100 is made of silicone rubber having a hardness in the range of [0HA, 140HA ]. The through hole 30 of the ear cap 100 is a stepped hole, 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 sequentially disposed 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 further comprises a conduit 50, the conduit 50 extending from the stepped surface 33 into the second sub-aperture 32, the conduit 50 being disposed within the second sub-aperture 32 and surrounding the first sub-aperture 31. Since the silicone rubber with the hardness range of [0HA, 140HA ] is soft, the comfort level of wearing the earcap 100 is improved, and the user experience is enhanced. Of course, the ear cap 100 can also be made of other flexible materials, and is not limited thereto.

Referring to fig. 7, the present application further provides an earphone 300. The earphone 300 comprises an earphone body 200 and the ear cap 100 of any of the above embodiments. The earphone main body 200 includes a connection portion 201, and the connection portion 201 is mounted in the through-hole 30.

The earphone 300 of the present application, by adopting the asymmetric structure that the curvature radius of the first region 41 of the earcap 100 is larger than the curvature radius of the third region 43, enables the earcap 100 to be more fit to the ear canal of the user, and enables the stress around the ear canal 401 (shown in fig. 1) to be uniform after the earcap 100 is worn, thereby avoiding the user from wearing the earcap 100 for a long time and generating the feeling of ear expansion, and improving the wearing comfort of the earcap 100.

Specifically, in some embodiments, the earphone body 200 is fixedly connected with the ear cap 100. For example, the connection portion 201 of the earphone body 200 is fixed in the through hole 30 by interference fit with the through hole 30. Because the earphone main body 200 is fixedly connected with the ear cap 100, the ear cap 100 can be prevented from falling off from the earphone main body 200, and the service life of the earphone 300 is prolonged. Specifically, the connection portion 201 and the through hole 30 may be connected by gluing, which is not limited herein.

In other embodiments, the earphone body 200 is removably connected to the ear cap 100. For example, the connection portion is engaged with or screwed into the through hole 30. 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 whole earphone 300, thereby saving the cost.

It should be noted that in some embodiments, the connecting portion 201 is solid and sealed. That is, sound cannot be transmitted in the connection portion 201. At this time, the earphone 300 can avoid external sound from being transmitted to human ears while being more attached to the ear canals of the users, so as to realize the noise reduction function. With reference to fig. 7, in some embodiments, the connecting portion 201 is a hollow structure, and the connecting portion 201 includes a sound outlet 2011, where the sound outlet 2011 is disposed on a side of the connecting portion 201 close to the first surface 10 of the earcap 100, so that sound played in the earphone 300 can be transmitted in the connecting portion 201 and transmitted to the ear of the person through the sound outlet 2011.
