[0034] Please see Figures 1 to 3 The headphone system 1000 provided in this embodiment includes headphones 100 and a charging case 300. The charging case 300 is used to charge the headphones 100. Since the headphone system 1000 in this embodiment includes headphones 100, it is understood that the headphone system 1000 includes at least the same beneficial effects as headphones 100. Therefore, please refer to the beneficial effects of headphones 1000 described below for the beneficial effects of headphones 100.
[0035] Please combine Figure 4The earphone 100 can be worn on the user's ear and can be used with mobile phones, computers, smart wearable devices (such as smartwatches, smart bracelets, smart glasses, and smart helmets), head-mounted displays, and virtual reality devices. It should be noted that the user's ear includes the auricle, external auditory canal, concha, helix, and antihelix. The auricle is the outer ear located on either side of the head. The upper part of the auricle is supported by elastic cartilage and covered with skin and a small amount of subcutaneous tissue. The lower part of the auricle includes the earlobe, which lacks cartilage and is mainly composed of connective tissue and fat, often used for blood collection. The auricle is a part used to collect sound waves, including the front of the auricle near the facial features and the back of the auricle opposite to the front. The external auditory canal is an organ structure inside the ear, connecting the outer and middle ear, and transmitting external sound waves to the eardrum. The helix is the outermost part of the ear's outer contour, also known as the edge of the auricle. It connects to the earlobe and is the curled part of the auricular cartilage, usually shaped like a question mark. It is located on the upper front of the auricle and extends towards the ear canal opening. The concha is a concave structure on the front of the auricle, the largest depression on its surface. The antihelix is the Y-shaped raised portion opposite the helix, composed of the antihelix body, the superior crus of the antihelix, and the inferior crus of the antihelix.
[0036] In some embodiments, when the earphone 100 is placed in the charging case 300, the charging case 300 can deliver electrical energy to the earphone 100 to charge the earphone 100. The charging case 300 is provided with a power terminal (not shown), and the earphone 100 is provided with a charging terminal. The charging terminal is at least partially housed in the housing 10 of the earphone 100 and exposed from the housing 10. The charging terminal 60 is electrically connected to the circuit board 30 of the earphone 100. When the earphone 100 is placed in the charging case 300, the charging terminal 60 and the power terminal are electrically connected.
[0037] Please see Figures 2 to 5 The earphone 100 includes a housing 10. The housing 10 includes a sound-emitting portion 11 and an ear clip portion 13. The sound-emitting portion 11 houses a speaker 20. The ear clip portion 13 includes a connecting portion 131 and a hook-shaped portion 133. The connecting portion 131 connects the sound-emitting portion 11 and the hook-shaped portion 133. When a user wears the earphone 100, the sound-emitting portion 11 is configured to be at least partially located within the user's concha. The ear clip portion 13 extends from the antihelix and the helix to between the auricle and the head. The ear clip portion 13 includes a flexible member 135 that forms the ear clip portion 13.
[0038] Specifically, the housing 10 is a structure used to house other components besides the housing 10 itself, and to house these other components within the housing 10. The housing 10 of this application is used to mount other components of the earphone 100 (e.g., speaker 20), and to house these other components within the housing 10, thus protecting them. The housing 10 can be made of plastic and / or metal, etc. When the housing 10 is made of plastic, it has good insulation properties, low cost, and light weight. When the housing 10 is made of metal, it has high strength, good wear resistance, and a long service life. When the housing 10 is made of a composite material of plastic and metal, it combines the advantages of high strength and light weight.
[0039] It is understood that the housing 10 is not only used to house other components, but also, when the user wears the headphones 100, at least a portion of the housing 10 contacts the user's ear, thereby securing the headphones 100 to the user's ear. Therefore, the size, shape, and material parameters of the housing 10 directly affect the user's comfort when wearing the headphones 100 and the acoustic performance of the headphones 100.
[0040] The sound outlet 11 houses components such as the speaker 20. The speaker 20 is fixed within the sound outlet 11, which provides a stable position for the speaker 20, ensuring its operation is unaffected by external vibrations or movement. Sound can propagate from the sound outlet 11 to the outside. When the user wears the headphones 100, the sound outlet 11 is at least partially located within the user's concha, close to the external auditory canal. The concha is a natural acoustic cavity that provides initial focusing and guidance of sound. The sound emitted by the speaker 20 propagates from the sound outlet 11 into the concha and then into the external auditory canal. This short propagation path improves sound transmission efficiency and enhances clarity. Furthermore, the short propagation path reduces energy loss during propagation, allowing the speaker 20 to output sound at lower power, thus extending the headphone 100's battery life.
[0041] The ear clip 13 is a component used to further secure the earphone 100 to the ear. The ear clip 13 includes a connecting part 131 and a hook-shaped part 133. The connecting part 131 connects the sound outlet part 11 and the hook-shaped part 133. In some embodiments, the connecting part 131 and the hook-shaped part 133 are an integral structure; in another embodiment, the connecting part 131 and the hook-shaped part 133 are two separate structures, which are subsequently combined into the ear clip 13 by a specific connection method. The "specific connection method" includes, but is not limited to, detachable connection methods, such as threaded connection, snap-fit, etc., and non-detachable connection methods, such as welding, gluing, etc. In some embodiments, the sound-emitting part 11 and the connecting part 131 may be an integral structure, that is, the sound-emitting part 11 and the connecting part 131 are a single unit. This improves the bonding strength between the sound-emitting part 11 and the connecting part 131, preventing separation of the sound-emitting part 11 and the connecting part 131 during the operation of the housing 10, thereby ensuring the stability and reliability of the housing 10. In other embodiments, the sound-emitting part 11 and the connecting part 131 are separate structures, that is, the sound-emitting part 11 and the connecting part 131 are two different structures. In one example, the sound-emitting part 11 and the connecting part 131 may be joined together by a detachable connection method, including but not limited to snap-fit connections or threaded connections. In another example, the sound-emitting part 11 and the connecting part 131 may be joined together by a non-detachable connection method, including but not limited to bonding or welding.
[0042] The hook-shaped part 133 is an extension of the ear clip part 13, and has a certain curvature. Its shape is curved or hook-shaped so that it extends from the antihelix and auricle of the user's ear to the space between the auricle and the head, thereby supporting and fixing the earphone 100. In this application, the auricle is defined based on the sagittal plane of the human body, including the opposite back and front of the auricle, with the front of the auricle being closer to the facial features than the back.
[0043] Please see Figure 4 and Figure 5 In some embodiments, the ear clip portion 13 includes a flexible member 135, which forms a connecting sub-portion 131 and a hook-shaped sub-portion 133, that is, the flexible member 135 forms the ear clip portion 13.
[0044] Specifically, the flexible component 135 can be made of soft and elastic materials, such as silicone, rubber, or polyvinyl chloride. Rubber includes, but is not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The flexible component 135 can return to its original shape after being subjected to force, effectively absorbing and dispersing the force. When the wearer's ear is subjected to external pressure or the earphone 100 slightly slides against the ear, the flexible component 135 can absorb and evenly distribute the external force, reducing the pressure directly acting on the auricle, thereby effectively alleviating discomfort and improving wearing comfort. Furthermore, the elastic properties of the flexible component 135 allow the ear clip 13 to form a good fit when worn, so that the hook-shaped part 133 firmly surrounds the ear helix and provides sufficient clamping force, ensuring that the earphone 100 is securely fixed to the ear and preventing the earphone 100 from sliding or falling off.
[0045] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the hook-shaped portion 133 extends first away from the sound-emitting portion 11 and then bends and extends towards the sound-emitting portion 11 so that the housing 10 forms a wearing space 101 for accommodating the auricle of a human body.
[0046] Specifically, the wearing space 101 is the area enclosed by the ear clip 13 and the sound outlet 11. Its size and shape are suitable for accommodating the auricle of the human body to ensure the stability and comfort of the headphones 100 when worn. The hook-shaped part 133 extends first away from the sound outlet 11, providing sufficient initial space to accommodate auricles of different sizes; then it bends and extends closer to the sound outlet 11 to help hook onto the auricle, improving the fixation performance of the headphones 100. The wearing space 101 can adapt to the natural curve of the auricle, thereby avoiding compression or slippage of the auricle and improving the comfort and stability when worn.
[0047] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the earphone 100 includes a first side 103 and a second side 105 opposite to each other in the first direction A1. The sound output part 11 is located on the first side 103 of the earphone 100, and the ear clip part 13 is located on the second side 105 of the earphone 100. The sound output part 11 includes a sound output surface 111 and a back surface 113 opposite to each other in the second direction A2. The sound output surface 111 is provided with a sound output hole 1111, which is used to allow the sound emitted by the speaker 20 to pass through to the outside of the sound output part 11. The first direction A1 is perpendicular to the second direction A2.
[0048] Although the earphone 100 has an irregular shape, according to the common definition of length, width, and height (thickness), the first direction A1 in this application can be understood as the length direction of the earphone 100, the second direction A2 can be understood as the width direction of the earphone 100, and the third direction A3 in the following text can be understood as the thickness direction of the earphone 100. When a user wears the earphone 100, the first direction A1 is approximately parallel to the sagittal plane of the human body, and the second direction A2 is approximately perpendicular to the sagittal plane of the human body.
[0049] The sound-emitting part 11 includes a sound-emitting surface 111 and a back surface 113 opposite to the sound-emitting surface 111 in the second direction A2. The sound-emitting surface 111 is provided with a sound-emitting hole 1111, through which the sound emitted by the speaker 20 can pass through the sound-emitting part 11 and propagate to the outside. When the user wears the headphones 100, the sound-emitting surface 111 faces the concha cavity, and the sound can directly enter the external auditory canal from the concha cavity, which can reduce the sound quality loss caused by sound scattering and improve the acoustic effect. The shape of the sound-emitting hole 1111 can be, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral or other polygons. There can be one or more sound-emitting holes 1111, which is not limited in this application. On the other hand, the back surface 113 is away from the concha cavity and is located on the side opposite to the sound-emitting surface 111 in the second direction A2. The back surface 113 can block the sound emitted by the speaker 20 from propagating in the opposite direction. Specifically, the back surface 113 can be flat, curved, or other geometrically shaped to fit the overall shape of the headphones 100 and meet acoustic requirements. The material of the back surface 113 can be a material with good sound absorption properties, such as composite materials, plastics, or metals coated with sound-absorbing coatings, to further reduce interference caused by sound propagation through the housing 10.
[0050] Please see Figure 2 , Figure 3 and Figure 5 The hook-shaped part 133 has a width dividing plane Pw. Within the first projection plane Pw where the width dividing plane Pw is located, the projection of the ear clip part 13 includes an inner contour and an outer contour. The outer contour has a protrusion BP, which is the point of the ear clip part 13 farthest from the sound outlet part 11 in the first direction A1. The inner contour has a concave point CP, which is located within the wearing space 101.
[0051] As mentioned earlier, the width direction is... Figure 2 or Figure 3The third direction A3 shown has a width-bisector plane that passes through the midpoint of the width and is perpendicular to the width direction. The inner contour of the projection of the ear clip 13 is the contour close to the sound outlet 11, and the outer contour of the projection of the ear clip 13 is the contour away from the sound outlet 11. The outer contour of the projection of the ear clip 13 is a convex surface protruding from the first side 103 to the second side 105, and the point of this convex surface farthest from the sound outlet 11 in the first direction A1 is the convex point BP. The inner contour of the ear clip 13 is a concave surface recessed from the first side 103 to the second side 105, and the point of this concave surface farthest from the sound outlet 11 in the first direction A1 is the concave point CP. The concave point CP is located inside the wearing space 101, and the convex point BP is located outside the wearing space 101.
[0052] Please see Figure 4 and Figure 5 In some embodiments, the maximum dimension of the outline of the hook-shaped part 133 projected in the first projection plane Pw is greater than or equal to 3 mm and less than or equal to 6 mm.
[0053] Specifically, the widest part of the outline of the hook-shaped portion 133 projected onto the first projection plane Pw can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, or 6mm. Preferably, the widest part of the outline of the hook-shaped portion 133 projected onto the first projection plane Pw is 4.5mm. The widest part of the outline of the hook-shaped part 133 projected onto the first projection plane Pw can be any value between 3.2 mm and 5 mm; or, the widest part of the outline of the hook-shaped part 133 projected onto the first projection plane Pw can be any value between 3.4 mm and 4.8 mm; or, the widest part of the outline of the hook-shaped part 133 projected onto the first projection plane Pw can be any value between 3.6 mm and 4.6 mm; or, the widest part of the outline of the hook-shaped part 133 projected onto the first projection plane Pw can be any value between 3.8 mm and 4.4 mm; or, the widest part of the outline of the hook-shaped part 133 projected onto the first projection plane Pw can be any value between 4 mm and 4.2 mm.
[0054] Understandably, the setting of the widest part of the hook-shaped portion 133, within the range of 3mm to 6mm, determines the contact area between the earphone 100 and the back of the ear 113 when worn. If the widest part of the hook-shaped portion 133 is less than 3mm, the contact area between the earphone 100 and the back of the ear 113 is small, resulting in poor fixation of the earphone 100, making it prone to slipping or falling off, thus affecting the stability of the fit. If the widest part of the hook-shaped portion 133 is greater than 6mm, the contact area between the earphone 100 and the back of the ear 113 is too large, which may cause discomfort during wear, especially during prolonged wear, increasing pressure and reducing comfort. The widest part of the projection of the hook-shaped portion 133 onto the first projection plane Pw is greater than or equal to 3mm and less than or equal to 6mm, which effectively increases the contact area between the earphone 100 and the back of the ear 113, thereby improving the fixation effect during wear, ensuring that the earphone 100 is securely fixed to the ear, and preventing slipping or falling off.
[0055] Please see Figure 4 and Figure 5 In some embodiments, the ear clip portion 13 further includes a deformable member 137. A flexible member 135 covers the outer surface of the deformable member 137 and together with the deformable member 137 forms a connecting sub-portion 131 and a hook-shaped sub-portion 133 (i.e., the ear clip portion 13). The deformable member 137 includes a first end and a second end opposite to each other. The first end is connected to the sound output portion 11. The deformable member 137 can change its bending angle under the action of force.
[0056] Specifically, the deformable part 137 is usually made of materials with a certain rigidity and deformation recovery ability, such as metal or plastic. Since everyone's auricle shape, helix size and wearing comfort requirements are different, the deformable part 137 can adjust the bending angle of the ear clip 13 under the action of external force according to the different shape of the auricle and the wearing conditions of the ear, so as to better adapt to the auricle shape of different people, make the earphone 100 fit the ear more tightly, and avoid the earphone 100 from slipping or causing discomfort due to improper wearing.
[0057] Please see Figure 4 and Figure 5 In some embodiments, the first end of the deformable member 137 is provided with a first connecting block 1371, and the second end of the deformable member 137 is provided with a second connecting block 1372. The first connecting block 1371 and the sound output part 11 are detachably connected.
[0058] In one example, the area of the projection of the first connecting block 1371 onto the first projection plane Pw and the area of the projection of the second connecting block 1372 onto the first projection plane Pw are both greater than the area of the projection of the deformable element 137 onto the first projection plane Pw.
[0059] Specifically, in one example, the first connecting block 1371 and the sound-emitting part 11 can be joined together by a detachable connection method, including but not limited to snap-fit connections or threaded connections. In another example, the first connecting block 1371 and the sound-emitting part 11 can be joined together by a non-detachable connection method, including but not limited to bonding or welding. Both the first connecting block 1371 and the second connecting block 1372 can be one or multiple; in this application, there is only one, which is easier to mold. Within the first projection plane Pw, the projected areas of the first connecting block 1371 and the second connecting block 1372 are both larger than the projected area of the deformable element 137. This increases the contact area between the first connecting block 1371 and the flexible element 135, as well as the contact area between the second connecting block 1372 and the flexible element 135. This helps to enhance the bonding force between the flexible element 135 and the deformable element 137, improves the connection strength between the flexible element 135 and the deformable element 137, and prevents the flexible element 135 and the deformable element 137 from falling off during wear due to frequent bending or external impact. This improves the service life and wearing stability of the earphone 100.
[0060] Please see Figure 4 and Figure 5 In another example, the area of the projection of the first connecting block 1371 onto the first projection plane Pw is greater than the area of the projection of the second connecting block 1372 onto the first projection plane Pw.
[0061] Specifically, since the first connecting block 1371 needs to connect with the sound output part 11, a larger first connecting block 1371 can provide a larger contact area, enhancing the connection strength between the flexible part 135 and the sound output part 11. This prevents the earphone 100 from loosening or falling off due to movement or external force during wear, ensuring the long-term stable use of the earphone 100. When the user wears the earphone 100, the hook-shaped part 133 area where the second connecting block 1372 is located will at least partially contact the back of the auricle 113. The relatively small second connecting block 1372 can control the size of the hook-shaped part 133, avoiding excessive pressure on the back of the auricle 113, thus improving wearing comfort while ensuring the earphone 100 is securely worn.
[0062] Please see Figure 4 and Figure 5 In some embodiments, the hardness of the flexible element 135 is less than the hardness of the deformable element 137.
[0063] Specifically, the flexible component 135 has a lower hardness than the deformable component 137, ensuring that the flexible component 135 better adapts to the shape of the auricle when subjected to external forces, providing a more comfortable wearing experience. The lower hardness of the flexible component 135 allows it to better adapt to different curves of the ear during wear, ensuring that the earphone 100 is less likely to slip or fall out. Simultaneously, the flexible component 135 effectively disperses and absorbs external forces, reducing ear discomfort or pain caused by improper wearing, increasing the wearing comfort of the earphone 100, and ensuring that it will not cause discomfort during prolonged wear, thereby improving the overall user experience.
[0064] Please see Figure 4 and Figure 5 In some embodiments, the flexible element 135 is made of silicone, and the deformable element 137 is made of titanium.
[0065] Specifically, silicone possesses excellent elasticity and deformation properties, with low hardness, allowing it to deform sufficiently under stress and return to its original shape after the stress is released. The flexible component 135 is made of silicone, enabling it to better conform to the curves of the ear and provide a more comfortable wearing experience. The lower hardness not only helps alleviate localized pressure on the ear and prevents a feeling of pressure, but also effectively adapts to individual differences in ear shapes, ensuring stability and comfort during wear. Furthermore, silicone has good fatigue resistance and durability, maintaining good deformation capacity during prolonged use and resisting aging or loss of elasticity, thereby extending the lifespan of the earphone 100. For example, the flexible component 135 is made of silicone with a hardness greater than or equal to 20A and less than or equal to 40A.
[0066] Titanium possesses high strength and rigidity, and compared to other metals, it has a lower density. The deformation component 137 is made of titanium, which allows it to maintain a certain level of rigidity and durability while reducing the overall weight of the earphone 100, thus reducing the burden of wearing it and improving comfort. It also enhances the overall stability and durability of the earphone 100. Therefore, the flexible component 135 is made of silicone, and the deformation component 137 is made of titanium, which not only effectively improves wearing comfort and stability but also enhances the user experience of the earphone 100, ensuring that the earphone 100 will not cause discomfort during prolonged wear.
[0067] Please see Figure 4 and Figure 5 In some embodiments, the cross-sectional area of the deformable member 137 obtained by a section perpendicular to its extension direction is greater than or equal to 0.3 mm and less than or equal to 0.7 mm.
[0068] The cross-section perpendicular to the extension direction of the deformable member 137 is also perpendicular to the first projection plane Pw. Specifically, the cross-sectional area of the deformable member 137 can be 0.3mm, 0.35mm, 0.4mm, 0.42mm, 0.45mm, 0.5mm, 0.53mm, 0.55mm, 0.6mm, 0.63mm, 0.65mm, or 0.7mm. Preferably, the cross-sectional area of the deformable member 137 is 0.5mm. The cross-sectional area of the deformable part 137 can be any value between 0.35mm and 0.65mm; or, the cross-sectional area of the deformable part 137 can be any value between 0.4mm and 0.63mm; or, the cross-sectional area of the deformable part 137 can be any value between 0.42mm and 0.6mm; or, the cross-sectional area of the deformable part 137 can be any value between 0.45mm and 0.55mm; or, the cross-sectional area of the deformable part 137 can be any value between 0.5mm and 0.53mm.
[0069] If the cross-sectional area of the deformable part 137 is less than 0.3 mm, the cross-sectional area of the deformable part 137 is too small, and the strength of the deformable part 137 itself is insufficient. This results in insufficient clamping force of the ear clip 13 on the auricle, making it impossible to effectively fix the earphone 100 on the auricle, and the earphone 100 is prone to slipping when worn. If the cross-sectional area of the deformable part 137 is greater than 0.7 mm, the cross-sectional area of the deformable part 137 is too large, which may lead to an excessively large contact area between the deformable part 137 and the auricle, resulting in increased contact pressure between the earphone 100 and the auricle, thus causing a feeling of pressure when wearing it and affecting wearing comfort. An excessively large cross-sectional area of the deformable part 137 may also cause the deformable part 137 to be unable to effectively adapt to the curve of the auricle, resulting in instability when wearing it, and may even cause the earphone 100 to slip or loosen, reducing wearing stability.
[0070] The cross-sectional area of the deformable part 137 is greater than or equal to 0.3 mm and less than or equal to 0.7 mm. It can provide sufficient clamping force and stability while ensuring the wearing comfort of the earphone 100, so as to prevent the earphone 100 from loosening or slipping during wearing, thereby improving the wearing comfort and stability.
[0071] Please see Figure 4 and Figure 5 In some embodiments, in the direction from the connecting sub-part 131 to the hook-shaped sub-part 133, the outer contour dimension of the flexible member 135 first decreases, then increases, and then decreases again.
[0072] Specifically, in the direction from the connecting part 131 to the hook-shaped part 133, the outer contour size of the flexible member 135 first decreases, providing clearance space for the antihelix and auricle, preventing excessive contact between the ear clip 13 and the antihelix and auricle, and avoiding the feeling of a foreign object caused by excessive tightness. Further, the outer contour size of the flexible member 135 increases, at least increasing the contact area of the hook-shaped part 133 with the back of the auricle 113, preventing the earphone 100 from slipping and loosening during wear. Further still, the outer contour size of the flexible member 135 decreases again.
[0073] Specifically, in the direction from the connecting part 131 to the hook-shaped part 133, the outer contour size of the flexible member 135 first decreases, providing clearance for the antihelix and auricle in the auricle, thereby preventing excessive contact between the ear clip 13 and the antihelix and auricle, reducing discomfort or foreign body sensation caused by excessive tightness. Next, the outer contour size of the flexible member 135 increases, at least increasing the contact area of the hook-shaped part 133 when it contacts the back of the auricle 113, thereby enhancing the fixation effect of the earphone 100 during wearing and preventing it from slipping off. Finally, since there is usually a certain curvature in the angle between the back of the auricle 113 and the head, the outer contour size of the flexible member 135 decreases again, better adapting to the angle between the back of the auricle 113 and the head. Reducing the outer contour size of the flexible member 135 allows the earphone 100 to fit more closely to this natural curvature, avoiding excessive gaps or pressure points. This ensures that the flexible part 135 can naturally bend along the shape of the back of the ear 113 during wear, thereby reducing the pressure on the head and improving wearing comfort.
[0074] Please see Figure 4 and Figure 5 In some embodiments, the housing 10 is provided with a receiving cavity 102, and the earphone 100 also includes a circuit board 30, a communication unit 40 and a battery 50. The circuit board 30 and the battery 50 are housed in the receiving cavity 102, and the communication unit 40 is disposed in the sound output part 11. The communication unit 40, the battery 50 and the speaker 20 are all electrically connected to the circuit board 30. The circuit board 30, the battery 50 and the speaker 20 are stacked sequentially in the direction from the back surface 113 of the housing 10 to the sound output surface 111.
[0075] The circuit board 30, battery 50, and speaker 20 are stacked sequentially from the back 113 of the housing 10 to the sound outlet 111, which saves space and allows for a reasonable layout of the components, making the headphone 100 compact overall. At the same time, the components are concentrated in the sound outlet 11, and the weight is concentrated in the part of the headphone 100 that is worn into the concha, so the ear clip 13 is less likely to slip off.
