Description

Technical Field

[0001] The present application relates to the field of Bluetooth headsets, and in particular to an ear clip-type headset and an earphone assembly. Background Art

[0002] Compared with in-ear or semi-in-ear headphones, ear clip headphones are more comfortable to wear and have lower requirements for curved surface design of the part that is in close contact with the ear canal. In addition, the clip-on ear hook configuration improves the tightness of wearing and is suitable for sports scenes. However, the front and rear cavities of existing ear clip headphones are basically coplanar and connected by a simple curved rod. When worn, the front and rear cavities jointly clamp the two sides of the auricle. After wearing for a long time, the pressure on the auricle becomes more and more obvious, and the claimed comfort is not achieved. Summary of the invention

[0030] The present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] The essence of headphones is a conversion unit that receives electrical signals from a media player or receiver and converts them into audible sound waves using a speaker close to the ear. Headphones are generally separated from media players and connected to the media player by wire or wirelessly. Headphones can be worn in the ear, semi-in-ear, head-mounted, ear-clip, and ear-hook styles. With the refinement of wearing needs and requirements, the styles of headphones may develop in a more diverse manner. Headphones can listen to audio alone without affecting others, and can also isolate the sounds of the surrounding environment. They are suitable for recording studios, DJs, travel, sports, or office study scenes. It can be understood that the scenes for wearing headphones have a trend of diversification and expansion, and the average wearing time of the user population is increasing.

[0032] Except for headphones, all other types of headphones have close contact with the auricle 1. Figure 1 , showing the basic structure of the auricle 1. Observing from the outer side of the auricle 1, the auricle 1 is, from the inside to the outside, the ear canal 11, the facial protrusion at the outlet of the ear canal 11 is the tragus 12, the protrusion on the opposite side of the tragus 12 is the antihelix 15, the depression between the tragus 12 and the antihelix 15 is the concha 13, the area of ​​the concha 13 around the outlet of the ear canal 11 is the concha cavity 131, the back of the concha 13 is the posterior medial side of the concha, the outermost protrusion of the auricle 1 is the helix 16, the lower end of the helix 16 is connected to the earlobe 17, and the back of the earlobe 17 is the posterior medial side of the earlobe.

[0033] The ear clip earphone 2 of the present application is adapted to the needs of long-term wearing and provides an earphone housing with high wearing comfort. Specifically, refer to Figures 2 to 5The ear clip earphone 2 of the present application has an earphone shell, which includes: a front cavity 21, a rear cavity 22 and an ear hook 23 connecting the front cavity 21 and the rear cavity 22. When worn, the front cavity 21 abuts against the concha cavity 131, and the rear cavity 22 abuts against the posterior inner side 18 of the earlobe. Therefore, the front cavity 21 and the rear cavity 22 are not on the same plane at any angle in space, and the entire ear clip earphone 2 is fixed on the auricle 1 through the spatial coordination of the ear hook 23.

[0034] Specifically, the front cavity 21 includes a key surface 211 and a sound outlet surface 212, wherein the sound outlet surface 212 is used to be in close contact with the concha cavity 131. In a possible implementation, the sound outlet surface 212 is configured as a hemisphere, and the bottom surface of the hemisphere is configured as the key surface 211, that is, the key surface 211 and the sound outlet surface 212 are arranged away from each other, and the front cavity 21 formed thereby is hemispherical. The hemispherical cavity can maximize the volume of the space with the same boundary, which is conducive to improving the accommodation of the front cavity 21, and providing convenience for improving the sound quality or functionality of the earphone. Further, the sound outlet surface 212 is provided with a sound outlet hole 213, and the sound outlet hole 213 is preferably provided at a position close to the ear canal 11, so that the sound waves are directly transmitted to the ear canal 11 to avoid sound leakage. The size of the sound outlet hole 213 is adapted to the efficiency of the vibration element of the earphone, and the shape of the sound outlet hole 213 is not particularly limited in this embodiment. In another possible implementation, in order to maximize the accommodation of the front cavity 21, the lateral dimension of the front cavity 21 may cover the space from the tragus 12 to the antihelix 15, that is, fill the entire cavum concha 131 as much as possible, but avoid backlogging of the cavum concha 131, the tragus 12 and the antihelix 15. However, if the front cavity 21 is required to be as small as possible, the lateral dimension of the front cavity 21 may only meet the installation requirements of the internal components. Furthermore, in order to improve the wearing comfort, the arc surface of the sound outlet surface 212 can be adjusted to adapt to the relatively flat shape of the cavum concha 131. For example, the flatness of the contact area close to the ear canal 11 is higher to reduce the pressure on the cavum concha 131, and the contact area close to the edge of the cavum concha 131 maintains a smaller arc to avoid falling off.

[0035] Furthermore, the key surface 211 can be set on the entire hemispherical bottom surface, with an area large enough to improve the operability of the key, and adapted to the shape of the hemispherical bottom surface, the key surface 211 can be set to a circle, and the keys can also be divided into several areas with different functions based on the center of the circle, for example, divided into multiple sector areas based on the center of the circle, or divided into multiple concentric rings based on the center of the circle, or can be matched in the form of sectors and concentric rings. In addition, in order to improve the recognition of the product, the key surface 211 can also be printed with a logo pattern, such as a brand LOGO or a decorative pattern; a hollow luminous area can also be set to achieve a lighting effect that changes dynamically with the rhythm, or to build a personalized luminous logo.

[0036] In summary, the front cavity 21 is the main structure for realizing the sound-generating function of the ear-clip earphone 2 of the present application, and the appearance when worn is also mainly provided by the front cavity 21 .

[0037] Furthermore, the tail cavity 22 abuts against the posterior medial surface 18 of the earlobe when the ear clip-type earphone 2 is worn. The posterior medial surface 18 of the earlobe is located at the transition position between the earlobe 17 and the concha 13. The concha 13 has cartilage, while the earlobe 17 has no cartilage. Thus, a soft nest-like structure is naturally formed in the transition position. The tail cavity 22 abuts against this nest-like structure, resulting in reduced mobility. Furthermore, the subcutaneous tissue of the earlobe 17 and its posterior medial surface is soft, and the nerve endings are sparsely distributed, which is not sensitive to the sense of pressure and is not likely to cause discomfort to the wearer. Adapting to the structure of the posterior medial surface 18 of the earlobe, the tail cavity 22 of the present application is configured in a teardrop shape, so that the tail cavity 22 is small at the top and large at the bottom when the ear clip-type earphone 2 is worn. The teardrop shape is also conducive to maximizing the capacity of the tail cavity 22. In a possible embodiment, the tail cavity 22 is used to accommodate a rechargeable battery, and a pair of metal contacts for charging are provided on the surface of the tail cavity 22; when it is necessary to optimize or expand the function of the ear clip-type earphone 2 of the present application, the accommodation space provided by the tail cavity 22 becomes an available part. Further, considering the wearing comfort and aesthetics, the lateral dimension of the tail cavity 22 should not exceed the range of the back of the helix 16, and the longitudinal dimension of the tail cavity 22 should not exceed the horizontal line of the end of the earlobe 17, so as to balance the size of the front cavity 21 and the tail cavity 22 as a whole, so as to avoid any part appearing too large and not meeting the current aesthetic standards.

[0038] The ear hook 23 is used to connect the front cavity 21 and the rear cavity 22, and also provides substantial support for the clamping function of the ear clip type earphone 2 of the present application. In this embodiment, the ear hook 23 includes three parts:

[0039] The first curved rod 231 extends from the front cavity 21 and crosses the antihelix 15. In one possible implementation, the first curved rod 231 extends from the top of the front cavity 21 and crosses the antihelix 15. Since the cartilage contour of the antihelix 15 is relatively prominent and the subcutaneous tissue is relatively thin, the first curved rod 231 needs to be provided with a certain convex curvature to avoid compressing the antihelix 15. In another possible implementation, the front wall 2311 of the first curved rod 231 is substantially flush with the button surface 211, or flush with the bottom surface of the hemispherical shape, so as to improve the overall aesthetics of the ear clip-on earphone 2; the decorative structure provided on the button surface 211 may also extend to the front wall 2311 of the first curved rod 231, and the decorative structure includes but is not limited to a printed indicative pattern and a hollow luminous area;

[0040] The second curved rod 232 is connected to the first curved rod 231 and half-wrapped the helix 16. The second curved rod 232 is a transition structure from the front to the back of the auricle 1 of the ear clip-type earphone 2 of the present application. The second curved rod 232 crosses the helix 16 in a nearly horizontal direction. The helix 16 is also a structure with a relatively prominent cartilage contour and thin subcutaneous tissue. The second curved rod 232 also needs to be provided with a certain convex arc to avoid compressing the helix 15. Unlike the first curved rod 231, the second curved rod 232 has a different extension direction from the first curved rod 231 and is not coplanar in space. The decorative structure provided on the key surface 211 can also extend to the front wall of the second curved rod 232, and the decorative structure includes but is not limited to printed indicative patterns and hollowed-out luminous areas.

[0041] The third curved rod 233 is connected to the second curved rod 232 and connected to the tail cavity 22 through the posterior medial surface of the concha 14. Since the wearing position of the second curved rod 232 is approximately located in the middle of the auricle 1, if the third curved rod 233 is directly extended from the end of the second curved rod 232 to the tail cavity 22, it will only extend along the concave groove between the auricle 1 and the concha 13, and will not achieve a stable ear hanging effect. Therefore, the third curved rod 233 is configured to abut against the concha 13 with cartilage from the posterior medial surface of the concha 14, and the lateral and medial surfaces of the concha 13 are appropriately clamped by the third curved rod 233 and the front cavity 21, and finally connected to the tail cavity 22 along the posterior medial surface of the earlobe 18, and abutted against the earlobe 17 through the tail cavity 22. Preferably, the third curved rod 233 is connected to the central axis 221 of the tail cavity 22 to maintain the structural balance of the tail cavity 22; since the third curved rod 233 is located on the back of the auricle 1, although a decorative structure can be configured, it should be understood that the decorative structure at this position is slightly less conspicuous.

[0042] The connection between the first curved rod 231, the second curved rod 232 and the third curved rod 233 should be rounded and smooth. Based on the complexity of the spatial structure, the structure of the entire ear hook 23 can be integrally formed by a mold, or integrally formed by 3D printing technology, or can be spliced ​​in sections. In addition, the interior of the ear hook 23 can also be a cavity structure, which can be used to arrange components and realize the complete functions of the ear clip type earphone 2 with the components in the front cavity 21 and the rear cavity 22.

[0043] It can be seen that the ear clip earphone 2 of the present application has a compact structure. When worn, there are several fixed points on the auricle 1: the sound outlet surface 212 of the front cavity 21, the third curved rod 233 and the rear cavity 22. Each fixed point is interlaced in space, and each fixed point does not produce strong pressure on the auricle. In terms of spatial structure, it cooperates with the physiological structure of the auricle 1 to achieve the effect of no swelling and pain after long-term wearing and not easy to fall off during exercise. The cross-sectional shapes of the first curved rod 231, the second curved rod 232 and the third curved rod 233 are adapted to the structure of the auricle 1. They are not completely similar, but the cross-sectional dimensions of the three can be similar. In order to further improve the wearing comfort, the cross-sectional dimensions of the second curved rod 232 can be slightly smaller than the first curved rod 231 and the second curved rod 232, and be flat.

[0044] The ear-clip earphone 2 of the present application should have the functions of playback and calling. In addition to the aforementioned earphone shell, it should also include the following functional modules to facilitate the formation of the earphone assembly: generating components contained inside the earphone shell, such as speakers and control circuit boards, and microphone-related components. When the ear-clip earphone of the present application is configured as a TWS earphone (TrueWireless Stereo), it should also include a wireless connection module, such as a Bluetooth module or an infrared receiving module, and also include a rechargeable battery for power feeding and a matching charging bin. The earphones of the present application can be configured in pairs, adapted for the left ear and the right ear respectively; they can also be used individually, but only adapted to one side of the ear canal 11, the left ear or the right ear.

[0045] In summary, the ear-clip earphone of the present application has an earphone shell, and the earphone shell includes: a front cavity, including a button surface and a sound output surface that are arranged away from each other, and abut against the concha cavity when worn; a tail cavity, which abuts against the posterior inner side of the earlobe when worn; and an ear hook, connecting the front cavity and the tail cavity. The present application also includes an earphone assembly, including an earphone and a feeding structure, wherein the earphone adopts the ear-clip earphone as described above. The ear-clip earphone of the present application changes the fixed position of the tail cavity on the auricle, so that the tail cavity is close to the posterior inner side of the earlobe with soft subcutaneous tissue, thereby reducing the pressure on the auricle.

[0046] The above embodiments are preferred implementation modes of the present application, but are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present application should be equivalent replacement methods and are included in the protection scope of the present application.
