Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to an ear hook and an ear hook device. Background Technology

[0002] Ear-hook devices are electronic or functional devices that are fixed to the auricle via ear hooks, including headphones, microphones, hearing aids, and glasses. When worn, the ear hook fits snugly against the auricle, providing a secure fit. However, ear hooks are difficult to adapt to different ear shapes and sizes, resulting in relatively poor wearing comfort and stability. Utility Model Content

[0003] This application provides an ear hook and an ear hook device to improve wearing comfort and stability.

[0004] The first aspect of this application provides an ear hook, including:

[0005] The main body, within which a support member is provided;

[0006] An elastic sleeve is fitted over the body and forms a receiving cavity between the sleeve and the body, the receiving cavity being filled with a shear-thickening fluid.

[0007] In one possible implementation, the receiving cavity includes at least two segments arranged sequentially along the extension direction of the body, and the shear-thickening fluid in the at least two segments has a different filling rate.

[0008] In one possible implementation, the body has a first end and a second end disposed opposite to each other, the first end being adjacent to the earlobe and the second end being adjacent to the helix foot;

[0009] The filling rate of the shear-thickening fluid in the segment adjacent to the first end is less than the filling rate of the shear-thickening fluid in the segment adjacent to the second end.

[0010] In one possible implementation, the at least two segments include a first segment and a second segment;

[0011] The first segment is located on the front of the auricle, and at least part of the second segment is located on the back of the auricle. The filling rate of the shear-thickening fluid in the first segment is greater than the filling rate of the shear-thickening fluid in the second segment.

[0012] In one possible implementation, the shear-thickening fluid in the first segment is filled at a rate of 70% to 90%.

[0013] The shear-thickening fluid in the second segment has a filling rate of 50% to 69%.

[0014] In one possible implementation, the cross-sectional dimensions of the receiving cavity gradually decrease along the direction from the second end to the first end.

[0015] In one possible implementation, the elastic sleeve includes:

[0016] A surrounding portion is fitted over the main body and spaced apart from the main body;

[0017] Two sealing parts are fitted over the main body and are respectively located at both ends of the surrounding part. The two sealing parts are also located between the surrounding part and the main body.

[0018] In one possible implementation, at least the material of the surrounding portion is silicone;

[0019] And / or, at least the Shore hardness of the surrounding portion is 15A-25A;

[0020] And / or, the elastic sleeve further includes an isolation portion disposed between the two sealing portions, the isolation portion being sleeved outside the main body portion and connected between the surrounding portion and the main body portion, and the isolation portion having a guide hole.

[0021] In one possible implementation, the body is made of silicone.

[0022] And / or, the support member is made of metal.

[0023] A second aspect of this application provides an ear-hook device, including the ear hook as described above.

[0024] The ear hook and ear hook device provided in this application include a main body and an elastic sleeve. A support member is provided inside the main body. The elastic sleeve is fitted over the main body and forms a receiving cavity with the main body, which is filled with a shear-thickening fluid. Utilizing the elastic properties of the elastic sleeve, pressure on the auricle can be reduced, improving wearing comfort. Utilizing the shear-thickening properties of the shear-thickening fluid, in conjunction with the elastic sleeve, the ear hook can achieve adaptive stiffness switching under different motion states, forming a dynamic damping response system. This solves the problem of traditional ear hooks having a motion displacement rate as high as 12-18%, suppressing the motion displacement rate to less than or equal to 3%, thus improving wearing stability and comfort.

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] In related technologies, ear hooks rely on a single bending shape, making it difficult to match the diverse curvatures of the auricle. Some ear hooks achieve multi-angle adjustment through two rotating axes to adapt to different auricle shapes, or they are directly clipped onto the auricle using rigid or semi-rigid ear clips, relying on material elasticity for fixation. However, this only achieves static angle adjustment and lacks real-time adaptive capabilities.

[0042] Ear hooks often have the following problems: inertial displacement during exercise causes a detachment rate of more than 15% (actual test data in running scenarios). Local pressure greater than 10g / mm² can cause redness and swelling of the ear; and when wearing glasses, the coefficient of friction is greater than 0.3, leading to pressure pain.

[0043] In addition, the ear hooks employ a modular design, resulting in complex assembly with more than eight parts and a yield rate below 85%. The material properties of the ear hooks are also not fully utilized; traditional silicone cushioning relies on compromises in thickness, which is often greater than or equal to 1.2mm, affecting aesthetics. Furthermore, the issue of high-frequency micro-vibration misalignment is not addressed, and a quantitative model of "pressure-time-fatigue" has not been established, leaving no standard for long-term wearing comfort.

[0044] The ear hook and ear hook device provided in this application include a main body and an elastic sleeve, with a receiving cavity formed between the elastic sleeve and the main body, and the receiving cavity filled with a shear-thickening fluid. Utilizing the elastic properties of the elastic sleeve, pressure on the auricle can be reduced, improving wearing comfort. By utilizing the shear-thickening properties of the shear-thickening fluid, in conjunction with the elastic sleeve, the ear hook can achieve adaptive stiffness switching under different motion states, forming a dynamic damping response system. This addresses the pain point of traditional ear hooks having a motion displacement rate as high as 12-18%, reducing the motion displacement rate to less than or equal to 3%, thus improving wearing stability and comfort.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] See Figures 1 to 3 This application provides an ear-hook device, which is an electronic product worn over the ear. Ear-hook devices include, but are not limited to, headphones, walkie-talkies, microphones, hearing aids, heart rate monitors, body temperature monitors, virtual reality (VR) devices, and augmented reality (AR) devices. The headphones can be open-ear wearable stereo (OWS) headphones or other types of headphones. The ear-hook device includes an ear hook 10 for securely wearing on the auricle 40.

[0047] The ear-hook device also includes a main unit 20 and a battery compartment 30. The main unit 20 is the core control or main function component of the ear-hook device, and the battery compartment 30 is used to provide power. For example, the main unit 20 of the headphones can perform audio processing, control, etc. The main unit 20 and the battery compartment 30 can be connected to the two ends of the ear hook 10 respectively, that is, the ear hook 10 is connected between the main unit 20 and the battery compartment 30.

[0048] like Figure 1As shown, one end of the ear hook 10 is connected to the main unit 20, and the other end of the ear hook 10 is connected to the battery compartment 30, enabling the battery compartment 30 to supply power to the main unit 20. The main unit 20 can at least partially extend into the ear canal, the battery compartment 30 can be adjacent to the earlobe, and the ear hook 10 can extend from the front of the auricle 40 to the back of the auricle 40, surrounding the helix and antihelix.

[0049] Continue reading Figures 1 to 3 The ear hook 10 includes a main body 11 and an elastic sleeve 13. A support member 12 is disposed inside the main body 11, and the elastic sleeve 13 is sleeved on the outside of the main body 11, forming a receiving cavity 14 between the elastic sleeve 13 and the main body 11. The receiving cavity 14 is filled with a shear-thickening fluid. The main body 11 can provide cushioning and isolation for the support member 12. For example, the main body 11 can cover the support member 12, or it can be sleeved on the support member 12 with a certain circumferential distance between the main body 11 and the support member 12.

[0050] The main body 11 can be made of silicone with a Shore hardness of 10A to 80A, exhibiting good softness and tear resistance, and conforming to the shape of the auricle. Alternatively, the main body 11 can be made of thermoplastic polyurethane, etc., and its thickness can range from 0.3mm to 0.8mm. Of course, the material and thickness of the main body 11 are not limited; other materials or thicknesses can be selected as needed.

[0051] The support member 12 serves as the skeleton of the ear hook 10, improving the stability of the ear hook 10 during wear. The support member 12 can be made of metal, including nickel, titanium, nickel-titanium alloys, copper-based alloys, and iron-based alloys; for example, the support member 12 could be made of titanium wire. In the example where the metal is a shape memory alloy, the support member 12 can be highly elastic, improving its resistance to deformation, and can also have a shape memory effect, automatically conforming to the auricle 40. One or more support members 12 can be provided as needed, and the support member 12 can also be designed with cutouts to reduce weight. The support member 12 can also enable electrical conduction between the main unit 20 and the battery compartment 30, allowing the battery compartment 30 to supply power to the main unit 20.

[0052] Continue reading Figures 1 to 3 An elastic sleeve 13 is fitted over the main body 11 and contacts the auricle 40. The elasticity of the sleeve 13 reduces pressure on the auricle 40, improving wearing comfort. The thickness of the elastic sleeve 13 can be 0.2mm to 0.8mm, for example, 0.3mm. A gap exists between the elastic sleeve 13 and the main body 11 to form a receiving cavity 14; that is, the elastic sleeve 13 and the main body 11 enclose and form a receiving cavity 14, which contains a shear-thickening fluid.

[0053] like Figure 1As shown, the two ends of the receiving cavity 14 are located on the front and back sides of the auricle 40, respectively, to clamp onto the auricle 40. That is, one end of the receiving cavity 14 is located in front of the auricle 40, and the other end of the receiving cavity 14 extends to the back of the auricle 40. The receiving cavity 14 is a closed cavity to prevent the shear-thickening fluid inside from overflowing. For example, after a non-Newtonian fluid is injected into the receiving cavity 14 through a syringe, the injection port is sealed using adhesive or the like. Alternatively, the receiving cavity 14 may have an opening, through which a non-Newtonian fluid is injected, and then the opening is sealed using a sealing element or the like.

[0054] Shear-thickening fluids (STFs) are fluid substances that exhibit shear-thickening properties, including but not limited to liquids, gels, or suspensions. Shear-thickening fluids typically consist of dispersed phase particles (thickening components) and a dispersion medium (base fluid), with the dispersed phase particles suspended in a liquid dispersion medium. The dispersed phase particles and dispersion medium are compatible and can utilize existing materials and components.

[0055] The viscosity of shear-thickening fluids increases significantly with increasing shear rate (or stress), and can even transform into a solid-like state under certain conditions. Thus, by utilizing the shear-thickening properties of shear-thickening fluids and in conjunction with the elastic sleeve 13, the ear hook 10 can achieve adaptive stiffness switching under different motion states, forming a dynamic damping response system. This addresses the pain point of traditional ear hooks 10 having a motion displacement rate as high as 12-18%, reducing the motion displacement rate to less than or equal to 3%.

[0056] Specifically, such as Figure 2 As shown, under normal conditions, the pressure is no higher than 10N and the acceleration is no higher than 15G, that is, the pressure is ≤10N and the acceleration is ≤10G. The shear thickening fluid remains in a liquid state and the viscosity is maintained at around 50mPa·s. The ear hook 10 is soft and can fit the auricle 40. With the elastic sleeve 13, it can achieve almost no pressure when wearing.

[0057] like Figure 3 As shown, under impact conditions, with acceleration greater than 15G or pressure greater than 10N, the shear-thickening fluid transiently solidifies, with a viscosity greater than 10000mPa·s, forming a rigid support. It can lock the ear hook at a 10° angle within 5ms, with a displacement of less than 0.1mm, to prevent misalignment.

[0058] The above-mentioned normal state can also be called the static state. At this time, the shear thickening fluid is in a liquid state, the elastic sleeve 13 is soft to the touch, and the support 12 can play a supporting role in a small range, making the ear hook 10 less likely to fall off and improving the wearing comfort of the ear hook 10.

[0059] The aforementioned impact state can also be called the motion state, including two modes: walking and running. In walking mode, the body maintains a walking posture, with one foot always in contact with the ground, and there is no airborne phase. The movement speed in walking mode is relatively slow, with a vibration frequency of 1-3 Hz. In running mode, the body maintains a running or jumping posture, with both feet in the airborne phase. The movement speed in running mode is faster, with a vibration frequency of 5-8 Hz. The damping of the shear-thickening fluid differs in different modes. In walking mode, local hardening reduces the frictional displacement of the ear hook 10; in running mode, overall hardening locks the shape of the ear hook 10.

[0060] In some possible implementations, the shear-thickening fluid is silica (SiO2) and polyethylene glycol (PEG) to form a damping medium. Silica is suspended and dispersed in polyethylene glycol, which has a molecular weight of 4000-6000, and the mass fraction of silica is 20%-60%, for example, 38% by mass.

[0061] Tests were conducted on traditional silicone ear hooks and the ear hook 10 in this embodiment. Traditional silicone ear hooks had an average motion displacement rate of 12%~18%, no acceleration trigger threshold (i.e., no dynamic damping adaptation), a peak pressure at auricle 40 greater than 90 kPa, a 2-hour discomfort rate of 22%~35%, poor temperature adaptability, and silicone hardening at low temperatures, resulting in an elasticity decrease of over 40%. The ear hook 10 in this embodiment had a motion displacement rate less than or equal to 3% (running mode), an acceleration trigger threshold greater than 15G (e.g., the instant of landing while running), a peak pressure at auricle 40 less than 35 kPa with a gradient distribution, a 2-hour discomfort rate of less than 5%, and good temperature adaptability, with viscosity fluctuations of less than 15% between -10℃ and 40℃.

[0062] Continue reading Figures 1 to 3 The receiving cavity 14 includes at least two segments arranged sequentially along the extension direction of the main body 11, and the shear-thickening fluid filling ratios of the at least two segments are different. The filling ratio refers to the proportion of space occupied by the shear-thickening fluid in the corresponding segment in the initial state, that is, the ratio of the volume occupied by the shear-thickening fluid to the total usable volume of the corresponding segment. By setting at least two segments arranged sequentially along the extension direction of the main body 11 and having at least two filling ratios, a suitable filling ratio can be selected according to the corresponding auricle 40 position, achieving a stepped density and ensuring both wearing stability and wearing comfort.

[0063] The main body 11 extends from the front of the auricle 40 to the back of the auricle 40, and the extension direction of the main body 11 is adapted to the shape of the auricle 40. At least two segments are arranged sequentially along the extension direction of the main body 11, that is, the arrangement direction of at least two segments is consistent with the extension line (axis) of the main body 11. In some examples, some segments are located on the front of the auricle 40 and some segments are located on the back of the auricle 40, and the segments can be divided by the upper ear root. In other examples, some segments extend from the front of the auricle 40 to the back of the auricle 40, that is, some segments cross the upper ear root. The dividing positions of each segment are not limited in the embodiments of this application.

[0064] At least two segments of the receiving cavity 14 have different filling rates. For example, the filling rates of each segment of the receiving cavity 14 are different; or, for example, some segments of the receiving cavity 14 have the same filling rate, but different from the filling rates of the remaining segments. The filling rates of the remaining segments can be all the same, partially the same, or different.

[0065] The fill rate can be greater than or equal to 50%, for example, 50%, 60%, 70%, 90%, or 100%. When the fill rate is less than 100%, the remaining space can be filled with air, or other fluids such as inert gases, as needed. The fill rate of each segment can be selected as needed, or it can be less than 50%.

[0066] The ear hook has a higher fill rate in the portion near the upper ear root, such as the part connecting to the speaker. This heavier portion of the ear hook receives reliable support from the upper ear root and is more secure. The remaining portion has a lower fill rate, such as the part connecting to the battery compartment. This lighter portion is more comfortable to wear while still being secure enough.

[0067] Two adjacent segments may or may not be connected. For example, cavity 14 may include two segments that are not connected or are connected. Or, cavity 14 may include three segments, in which two segments are adjacent and connected and not connected to another segment, or all three segments are not connected, or all three segments are connected to each other.

[0068] In some possible implementations, an isolation section can be provided between two adjacent segments to separate them. The isolation section may have at least one flow-guiding hole as needed to connect the two segments on either side of the isolation section. For example, the isolation section may have a honeycomb structure, using the capillary action of the flow-guiding holes to balance fluid distribution and prevent localized drying of the receiving cavity 14. The shape of the flow-guiding holes can be circular, elliptical, rectangular, etc., and the diameter of the flow-guiding holes can be less than 0.5 mm, for example, 0.2 mm. When the flow-guiding hole is circular, its diameter is the equivalent diameter of the guiding flow-guiding hole; when the flow-guiding hole is non-circular, its diameter is the equivalent diameter of the guiding flow-guiding hole.

[0069] Continue reading Figures 1 to 3 The main body 11 has a first end and a second end disposed opposite to each other. The first end is adjacent to the earlobe, and the second end is adjacent to the crus of the helix. The filling rate of the shear-thickening fluid in the segment adjacent to the first end is less than the filling rate of the shear-thickening fluid in the segment adjacent to the second end. The first end and the second end of the main body 11 are disposed opposite to each other along the extending direction of the main body 11. The first end of the main body 11 is located behind the auricle 40, adjacent to the earlobe, such as... Figure 1 As shown at point B, this end is located in the rear half of the ear hook 10 and can be connected to the battery compartment 30. The second end of the main body 11 is located in front of the auricle 40, near the helix foot, as shown... Figure 1 As shown at point A, this end is located in the front half of the ear hook 10 and can be connected to the host 20.

[0070] The segment adjacent to the first end is located in the rear half of the ear hook 10. This segment has a lower shear-thickening fluid filling rate, which reduces weight, improves wearing comfort, prevents slippage even overnight, and reduces the feeling of wearing it. The segment adjacent to the second end is located in the front half of the ear hook 10. This segment has a higher shear-thickening fluid filling rate, which improves stability and reduces the rate of motion displacement. Thus, the asymmetric fluid distribution within the receiving cavity 14 of the ear hook 10 reduces auricular pressure by 60% compared to traditional silicone ear hooks, resulting in a discomfort rate of less than 5% after 2 hours of wear. This balances wearing stability and comfort, demonstrating ergonomic advantages.

[0071] like Figure 1 As shown, the cross-sectional size of the receiving cavity 14 gradually decreases from the second end to the first end. That is, the cross-sectional size of the receiving cavity 14 near the second end is larger, and the size of the receiving cavity 14 near the first end is smaller. In this way, more shear-thickening fluid is distributed at the second end, making the second end heavier and the first end lighter, thus reducing the overall weight of the ear hook 10. Furthermore, the distribution of the shear-thickening fluid is consistent with the force applied to the ear hook 10, which can also ensure the fixation of the second end to the auricle 40 and improve the stability of the ear hook 10.

[0072] In some possible examples, the cross-sectional dimensions of the main body 11 gradually decrease along the direction from the second end to the first end, while the cross-sectional dimensions of the protective sleeve remain unchanged. In other possible examples, the cross-sectional dimensions of the main body 11 remain unchanged along the direction from the second end to the first end, while the cross-sectional dimensions of the protective sleeve gradually decrease. In still other possible examples, the cross-sectional dimensions of both the main body 11 and the protective sleeve gradually decrease along the direction from the second end to the first end, and the rate of change of the cross-sectional dimensions of the main body 11 is greater than the rate of change of the cross-sectional dimensions of the protective sleeve.

[0073] In some possible implementations, at least two segments include a first segment 15 and a second segment 16; the first segment 15 is located on the front of the auricle 40, and at least part of the second segment 16 is located on the back of the auricle 40, wherein the filling rate of the shear-thickening fluid in the first segment 15 is greater than the filling rate of the shear-thickening fluid in the second segment 16. Figure 1 As shown, at least two segments include a first segment 15 and a second segment 16. The first segment 15 is located on the front of the auricle 40, and the second segment 16 is partially or entirely located on the back of the auricle 40. For example, the second segment 16 is partially located on the front of the auricle 40 and partially located on the back of the auricle 40, that is, the second segment 16 crosses the upper ear root, and the second part can be mostly located on the back of the auricle 40.

[0074] The shear-thickening fluid filling rate in the first segment 15 is greater than that in the second segment 16, meaning the first segment 15 has a higher filling rate to improve wearing stability, while the second segment 16 has a lower filling rate to improve wearing comfort. The first segment 15 and the second segment 16 can be connected, allowing the shear-thickening fluid to flow between them, preventing localized drying within the receiving cavity 14. For example, if the first segment 15 deforms, the shear-thickening fluid can enter the second segment 16. The first segment 15 can then recover with the assistance of a support member, and the shear-thickening fluid can return to the first segment 15 through capillary action.

[0075] In some possible examples, the shear-thickening fluid in the first segment 15 is 70% to 90% filled; the shear-thickening fluid in the second segment 16 is 50% to 69% filled. For example, the shear-thickening fluid in the first segment 15 is 80% filled, and the shear-thickening fluid in the second segment 16 is 60% filled.

[0076] Continue reading Figures 1 to 3The elastic sleeve 13 includes: a surrounding portion, fitted over the body 11 and spaced apart from the body 11; and two sealing portions, each fitted over the body 11 and respectively disposed at both ends of the surrounding portion, with the two sealing portions also located between the surrounding portion and the body 11. The surrounding portion is annular, fitted over the body 11 and spaced apart from the outer circumferential surface of the body 11. The two sealing portions are located at both ends of the surrounding portion and between the surrounding portion and the body 11 to achieve a seal between the surrounding portion and the body 11, thereby preventing leakage of the shear-thickening fluid. The sealing portions can be integrally formed with the surrounding portion, i.e., the sealing portion and the surrounding portion are integrally molded. Alternatively, the sealing portions can be separate structures from the surrounding portion, connected by bonding, hot pressing, or other methods.

[0077] In some possible examples, at least the surrounding portion is made of silicone; and / or, at least the surrounding portion has a Shore hardness of 15A-25A. Both the surrounding portion and the sealing portion are made of silicone to facilitate their connection and molding. The Shore hardness of both the surrounding portion and the sealing portion is 15A-25A, for example, 20A, to provide an ultra-soft feel. For example, the surrounding portion, the sealing portion, and the body 11 are all made of silicone for ease of fabrication.

[0078] In some possible examples, the elastic sleeve 13 also includes an isolation portion disposed between the two sealing portions. The isolation portion is fitted over the main body 11 and connected between the surrounding portion and the main body 11. A flow-guiding hole is provided on the isolation portion. The isolation portion is disposed between the two sealing portions to divide the receiving cavity 14 into at least two segments. The flow-guiding hole on the isolation portion can also connect the two segments on both sides to balance the distribution of shear thickening fluid, prevent local drying, and improve the wearing comfort and stability of the ear hook 10.

[0079] This application provides an ear hook 10, which includes a main body 11 and an elastic sleeve 13. A support member 12 is disposed inside the main body 11. The elastic sleeve 13 is sleeved outside the main body 11, forming a receiving cavity 14 between the sleeve and the main body 11. The receiving cavity 14 is filled with a shear-thickening fluid. Utilizing the elastic properties of the elastic sleeve 13, pressure on the auricle 40 can be reduced, improving wearing comfort. By utilizing the shear-thickening properties of the shear-thickening fluid, in conjunction with the elastic sleeve 13, the ear hook 10 can achieve adaptive stiffness switching under different motion states, forming a dynamic damping response system. This solves the problem of traditional ear hooks having a motion displacement rate as high as 12-18%, reducing the motion displacement rate to less than or equal to 3%, thus improving wearing stability and comfort.
