Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to an ear hook and a headphone. Background Technology
[0002] Headphones are a pair of transducers that can be used with electronic devices such as mobile phones and computers. They receive electrical signals from media players or receivers and convert them into audible sound waves using speakers placed close to the ears. Based on whether headphones block the ear canal, they can generally be divided into open-back headphones, semi-open-back headphones, and closed-back headphones.
[0003] In some headphones, such as open-back headphones, the ear hooks fit snugly against the ear when worn, providing a secure fit. However, without memory metal, the ear hooks are thicker to ensure strength, resulting in poorer local elasticity and a smaller overall opening range. This makes them unsuitable for different ear shapes and sizes, leading to poor wearing comfort and stability.
[0004] Therefore, it is urgent to solve the technical problems of poor wearing comfort and stability of headphones. Utility Model Content
[0005] This utility model provides an ear hook and headphones to solve the technical problems of poor wearing comfort and stability of headphones.
[0006] To achieve the above objectives, this utility model provides an ear hook, including a main body extending along the root of the outer ear, the main body being a flexible component, and having at least two ventilation holes arranged at intervals along the extending direction of the main body.
[0007] The present invention provides an ear hook that increases breathability by having at least two ventilation holes spaced apart inside the main body. The at least two ventilation holes are arranged at intervals along the extension direction of the main body, which helps to improve the elastic deformation ability of the ear hook, increase the overall opening range of the ear hook, and allow the bending shape of the ear hook to elastically deform according to the shape of the user's outer ear, thereby improving the wearing comfort and stability.
[0008] In one possible implementation, the vent is a through hole penetrating the side wall of the main body, and the central axis of each vent extends in the same direction.
[0009] In one possible implementation, the main body includes at least two connecting sections connected sequentially along the extension direction of the main body, the connection position of two adjacent connecting sections is a solid structure, and the vent is located within the connecting section.
[0010] In one possible implementation, the inner wall of the main body has at least two first protrusions and at least one first groove spaced apart, the inner wall of the main body facing the root of the auricle, the surface of the first protrusions being a smooth curved surface, and the first groove being formed between two adjacent connecting segments. By spaced arrangement of multiple first protrusions and multiple first grooves on the inner wall of the main body, the deformation of the ear hook can be further increased, reducing the pressure of the ear hook on the auricle during wearing and improving wearing comfort.
[0011] In one possible implementation, the outer wall of the main body has at least two second protrusions and at least one second groove arranged at intervals, the second groove being formed between two adjacent connecting sections, the second groove being positioned opposite to the first groove.
[0012] In one possible implementation, the ear hook also includes a fixing part connected to one end of the main body, the fixing part being a rigid component;
[0013] The main body is a flexible component with memory function.
[0014] This utility model also provides an earphone, including an earphone body and the aforementioned ear hook, wherein at least one end of the ear hook is connected to the earphone body.
[0015] In one possible implementation, the earphone body includes a housing having a receiving cavity, and the ear hook fixing portion is embedded in the receiving cavity.
[0016] In one possible implementation, along a first direction, the distance between the inner wall surface of the main body and the headphone body is H1, where 14mm ≤ H1 ≤ 16mm.
[0017] In one possible implementation, along the first direction, the distance between the end of the ear hook furthest from the headphone body and the center position of the headphone body is H2, where 16mm ≤ H2 ≤ 20mm.
[0018] In one possible implementation, the headphones are clip-on headphones; or, the headphones are open-back headphones.
[0019] This utility model provides an ear hook and earphone. By providing at least two ventilation holes spaced apart in the main body, the breathability of the ear hook is increased, and the elastic deformation ability of the ear hook is also improved. The ear hook is softer, more elastic, has better adjustable clamping force, and is more secure and comfortable to wear. It can fit various ear shapes, improve the applicability of the earphone, and meet the usage requirements of more users.
[0020] The present invention provides an ear hook and earphone with regularly distributed vent holes, which makes the ear hook form a cushioning effect similar to an air cushion. It can undergo local deformation when worn, reducing local pressure on the back of the ear and thus improving the comfort of use. In addition, the regularly distributed vent holes can increase the overall opening range of the ear hook while maintaining a relatively thin thickness and ensuring its structural strength.
[0021] The present invention provides an ear hook and earphone, wherein the inner sidewall of the main body has at least two first protrusions and at least two first grooves arranged at intervals. The surface of the first protrusion is a smooth curved surface, which makes it easier for the highest point of the first protrusion to contact the skin on the back of the ear, thereby increasing the contact area between the first protrusion and the back of the ear, reducing the local pressure on the ear, and improving wearing comfort.

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0048] People of different ages and ear sizes have different ear shapes. In related technologies, headphone ear hooks are usually made of solid soft rubber body with a hard rubber inner mold, or solid soft rubber body with a memory metal inner mold. The problems are: the flexibility is generally poor, the overall opening range is small, and the shape of the ear hook does not match the outer ear during wearing, which can easily cause the headphones to fall off or pinch the ears, affecting the comfort and stability of wearing headphones.
[0049] In view of this, the ear hook and earphone provided by this utility model improve the elastic deformation ability of the ear hook and increase the overall opening range of the ear hook by providing at least two ventilation holes spaced apart in the main body and arranging the at least two ventilation holes spaced apart along the extension direction of the main body. This allows the bending shape of the ear hook to elastically deform according to the shape of the user's outer ear, thereby improving the wearing comfort and stability.
[0050] The ear hook and headphones provided in the embodiments of this utility model are described below with reference to the accompanying drawings.
[0051] refer to Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an ear hook, including a main body 10 extending along the root of the outer ear 30. The main body 10 is a flexible part, and at least two ventilation holes 12 are provided in the main body 10. The at least two ventilation holes 12 are arranged at intervals along the extending direction of the main body 10.
[0052] The present invention provides an ear hook that increases the breathability of the ear hook by providing at least two ventilation holes 12 spaced apart in the main body 10. It also helps to improve the elastic deformation ability of the ear hook and increase the overall opening range of the ear hook, so that the bending shape of the ear hook can be elastically deformed according to the shape of the user's outer ear 30, thereby improving the wearing comfort and stability.
[0053] In one possible implementation, the number of ventilation holes 12 opened in the main body 10 can be 2, 3, 4, 8, 10 or more, without specific limitation here.
[0054] In one possible implementation, the main body 10 is a flexible component with shape memory function to avoid failing to realize the ear hook function. For example, the flexible component is made of a soft elastic material.
[0055] The main body 10 is arc-shaped, with an inner wall that faces the center of the arc segment of the main body 10 and an outer wall that faces away from the center of the arc segment of the main body 10. This application does not limit the degree of curvature of the main body 10.
[0056] In one possible implementation, the main body 10 is roughly in the shape of a "C" or other curves, specifically the outline of the base of the auricle 30, which can fit well with the base of the user's auricle 30, thereby playing a certain role in preventing it from falling off.
[0057] refer to Figure 3As shown, when worn, the main body 10 fits snugly against the base of the outer ear 30. The main body 10 is a flexible component, giving the ear hook a certain degree of flexibility and deformation recovery capability. After deformation, it can spring back to its original shape, thereby generating a clamping force on the ear. There is no need to install memory metal inside the ear hook, eliminating the pressure of memory metal on the ear and improving wearing comfort. The ear hook retains its deformation memory function thanks to the inherent memory function of the material used in the main body 10.
[0058] In one possible implementation, the main body 10 is a flexible component. For example, the main body 10 may be made of flexible materials such as silicone, thermoplastic polyurethane (TPU), or thermoplastic elastomer (TPE), which have good elastic deformation and deformation recovery capabilities, as well as good flexibility and wear resistance, making it more durable.
[0059] The inner wall of the main body 10 has a plurality of first protrusions 14 and a plurality of first grooves 15 arranged at intervals. The inner wall of the main body 10 is directed toward the root of the auricle 30. By arranging a plurality of first protrusions 14 and a plurality of first grooves 15 at intervals on the inner wall of the main body 10, the deformation of the ear hook can be further increased, reducing the pressure of the ear hook on the auricle when wearing it and improving the comfort of wearing it.
[0060] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, the surface of the first convex 14 is a smooth curved surface, which makes it easier for the highest point of the first convex 14 to contact the skin behind the ear, increasing the contact area between the first convex 14 and the back of the ear, reducing local pressure on the ear, and improving wearing comfort.
[0061] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 3 As shown, the main body 10 has multiple ventilation holes 12, which are spaced apart along the extending direction of the main body 10. In this example, the extending direction of the main body 10 is along the root of the user's outer ear. This regular distribution of the ventilation holes 12 helps to provide uniform ventilation.
[0062] The vent 12 is a through hole that penetrates the side wall of the main body 10. The vent 12 is a through hole and has good air permeability.
[0063] In one possible implementation, since the main body 10 extends along the root of the auricle and is arc-shaped, the central axis of each vent 12 extends in the same direction, so that the central axis of each vent 12 does not point to the center of the arc segment of the main body 10, but the extension direction of the central axis of each vent 12 is perpendicular to the plane where the arc segment of the main body 10 is located, thereby improving the ventilation effect.
[0064] In other possible implementations, the extension direction of the central axis of each vent 12 may also be inconsistent.
[0065] The ventilation holes 12 make it easier for the main body 10 to deform towards the side closer to the center of the arc or away from the center of the arc, thereby increasing the overall opening range of the ear hook and providing a comfortable wearing experience for different people with different ear shapes.
[0066] refer to Figure 2 and Figure 4 As shown, this application achieves the hollowing out of the ear hook through the ventilation hole 12, so that the ear hook forms a flexible air cushion-like function, which improves the ability to undergo local deformation when worn and reduces the local pressure on the auricle.
[0067] In one possible implementation, the vent 12 can be a circular vent, a polygonal vent, an elliptical vent, a heart-shaped vent, a racetrack-shaped vent, etc.
[0068] In one possible implementation, the main body 10 includes at least two connecting segments 11 connected sequentially along the extending direction of the main body 10. The connection position between two adjacent connecting segments 11 is a solid structure, and the vent 12 is located within the connecting segment 11. In this structure, the connecting segments 11 restrain each other, and the connection position between adjacent connecting segments 11 is set as a solid structure. This solid structure, spaced apart from the vent 12, increases the overall opening range while maintaining a relatively thin thickness, ensuring structural strength, guaranteeing the clamping force of the ear hook, and improving wearing comfort.
[0069] In one possible implementation, the number of connecting sections 11 can be 2, 3, 4, 6, 8, 10, or 12, etc., without specific limitations here.
[0070] In one possible implementation, there may be multiple connecting joints 11, and the vents 12 may be located in some of the connecting joints 11, while the remaining connecting joints 11 may not have vents 12. Alternatively, each connecting joint 11 may have vents 12 inside, which is beneficial for improving the breathability and elastic deformation capacity of the ear hook.
[0071] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 3 As shown, the first groove 15 is formed between two adjacent connecting sections 11. This structure makes the ear loop relatively thin at the location of the first groove 15, which helps the main body 10 to elastically deform towards the inner wall of the main body 10.
[0072] In one possible implementation, the number of first convex bulges 14 can be 2, 3, 4 or more, without specific limitation here. The number of first grooves 15 can be one less than the number of connecting joints 11.
[0073] In one possible implementation, the outer wall of the main body 10 has at least two second protrusions 16 spaced apart and at least one second groove 17, the second groove 17 being formed between two adjacent connecting sections 11, and the second groove 17 being positioned opposite to the first groove 15. At the location of the second groove 17, the ear loop is relatively thin, which facilitates elastic deformation of the main body 10 towards the outer wall of the main body 10.
[0074] refer to Figure 6 and Figure 8 As shown, since the second groove 17 is positioned opposite to the first groove 15, the main body 10 can undergo more flexible elastic deformation, making the ear hook suitable for a wider range of users.
[0075] In one possible implementation, the second groove 17 is an arc-shaped groove, and the first groove 15 is an arc-shaped groove.
[0076] In one possible implementation, the number of second convex hulls 16 can be 2, 3, 4 or more, without specific limitation here. The number of second grooves 17 can be one less than the number of connecting joints 11.
[0077] In one possible implementation, the ear hook also includes a fixing part 13 connected to one end of the main body 10. The fixing part 13 is used to connect the ear hook to the headphone main body 20.
[0078] In one possible implementation, the fixing part 13 is a rigid component, which provides good mechanical strength and is not easily damaged, thereby improving the stability of the connection between the ear hook and the headphone body 20.
[0079] In one possible implementation, the fixing part 13 may be crescent-shaped. Of course, the fixing part 13 may also be circular, straight, curved or other shapes.
[0080] In one possible implementation, the fixing part 13 and the main body part 10 can be an integral structure, ensuring the structural strength of the ear hook itself.
[0081] The ear hook provided by this utility model has fewer parts, resulting in lower part and assembly costs.
[0082] In one possible implementation, the surface of the ear hook can be a frosted surface or a textured surface structure, which increases the friction between the ear hook and the user's skin, thereby reducing the sliding performance of the ear hook relative to the user's skin and improving the stability of wearing the headphones.
[0083] refer to Figure 5 and Figure 6 As shown, this utility model also provides an earphone, including an earphone body 20 and the aforementioned ear hook, one end of which is connected to the earphone body 20. The earphone provided by this utility model can be an open-back earphone. Open-back earphones do not close the ear canal when worn, keeping the ear canal opening open, which helps protect hearing and prevents ear stuffiness, improving the user's wearing experience.
[0084] In one possible implementation method, refer to Figure 6 and Figure 7 As shown, the headphone body 20 includes a shell 21, and the shell 21 has a receiving cavity 211. The ear hook fixing part 13 is embedded in the receiving cavity 211. This makes the assembly of the ear hook and the headphone body 20 convenient and the connection highly reliable.
[0085] In one possible implementation method, refer to Figure 1 and Figure 7 As shown, the center of the back of the fixing part 13 is connected to the main body 10, and a snap-fit groove 18 is formed between the edge of the back of the fixing part 13 and the main body 10. The outer shell 21 also has a stop part 212 located in the receiving cavity 211. The stop part 212 extends into the snap-fit groove 18. By blocking the fixing part 13 through the stop part 212, the fixing part 13 is effectively prevented from coming out of the receiving cavity 211, thereby improving the stability of the connection between the earphone body 20 and the ear hook.
[0086] In one possible implementation, the distance between the inner wall surface of the main body 10 and the headphone body 20 along the first direction is H1, wherein 14mm≤H1≤16mm.
[0087] In this example, the first direction reference Figure 5 The arrow Z in the diagram indicates the direction.
[0088] If the gap H1 is too large, it will affect the fit between the ear hook and the outer ear 30, causing the headphones to easily come loose. If the gap H1 is too small, the ear hook may pinch the ear, causing discomfort. This application controls the gap to be 14mm≤H1≤16mm, which ensures both stability and comfort.
[0089] In one possible implementation, the spacing H1 can be, for example, 14 mm, 14.6 mm, 15 mm, 15.5 mm, or 16 mm.
[0090] In one possible implementation, along the first direction, the distance between the end of the ear hook furthest from the headphone body 20 and the center position of the headphone body 20 is H2, where 16mm≤H2≤20mm.
[0091] If the spacing H2 is too large, the end of the ear hook furthest from the headphone body 20 will extend too far into the lower part of the ear, affecting the aesthetics of wearing it and making it difficult to save material and reduce costs. If the spacing H2 is too small, the headphones will easily fall off, especially during exercise, which will affect the stability of wearing the headphones. This application ensures that 16mm≤H2≤20mm, which helps to reduce the length of the end of the ear hook furthest from the headphone body 20 extending into the lower part of the ear, ensuring the aesthetics of wearing it and improving the stability of wearing it.
[0092] In one possible implementation, the spacing H2 can be, for example, 16 mm, 17 mm, 18 mm, 19.5 mm, 19 mm, or 20 mm.
[0093] The headphone body 20 also includes a battery, a main control board, and a sound receiving / transmitting component housed within a cavity 211. When worn, the headphone body 20 is worn in front of the ear, with the ear hook fitting snugly against the upper ear root and the back of the ear. The ear hook and the headphone body create a clamping force on the ear, thereby ensuring comfort and stability when worn.
[0094] In one possible implementation, the earphone body 20 also includes a Bluetooth device disposed within the receiving cavity 211, enabling the earphone to have Bluetooth functionality.
[0095] The earphone provided by this utility model can also be a clip-on earphone. The clip-on earphone is fixed to the human ear by the clamping force formed by its two ends. The ear hooks mentioned above allow the clip-on earphone to move elastically, improving the comfort and stability of wearing it.
[0096] The present invention provides an ear hook and earphone, which increases the breathability of the ear hook by providing at least two ventilation holes 12 spaced apart in the main body 10. It also helps to improve the elastic deformation ability of the ear hook, making the ear hook softer and more elastic, with better adjustable clamping force, high wearing firmness and comfort, and can be adapted to various ear shapes, thereby improving the applicability of the earphone and meeting the usage requirements of more users.
[0097] The present invention provides an ear hook and earphone with regularly distributed vent holes 12, which form a cushion-like effect, allowing the ear hook to undergo local deformation when worn, reducing local pressure on the back of the ear and thus improving comfort. In addition, the regularly distributed vent holes 12 can increase the overall opening range of the ear hook and maintain a thinness while ensuring the structural strength of the ear hook itself.
[0098] The present invention provides an ear hook and earphone, wherein the inner sidewall of the main body 10 has at least two first protrusions 14 and at least one first groove 15 arranged at intervals. The surface of the first protrusions 14 is a smooth curved surface, which makes it easier for the highest position of the first protrusions 14 to contact the skin behind the ear, increasing the contact area between the first protrusions 14 and the back of the ear, reducing the local pressure on the ear, and improving wearing comfort.
[0099] It should be noted that the numerical values and ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.
