[0031] Please see Figure 1 to Figure 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.

[0032] Please combine Figure 4 The 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.

[0033] 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.

[0034] Please see Figure 2 to Figure 5The earphone 100 includes a housing 10. The housing 10 includes a sound-emitting part 11 and an ear clip 13. The sound-emitting part 11 has a receiving cavity 102, and a speaker 20 is disposed within the receiving cavity 102. The ear clip 13 includes a connecting part 131 and a hook-shaped part 133. The connecting part 131 connects between the sound-emitting part 11 and the hook-shaped part 133. When the user wears the earphone 100, the sound-emitting part 11 is configured to be at least partially located within the user's concha cavity, and the ear clip 13 extends from the antihelix and the helix to the space between the auricle and the head. When the user wears the earphone 100, the human ear is housed in the wearing space 101, and the sound-emitting part 11 and the hook-shaped part 133 respectively abut against opposite sides of the human ear. The force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear is greater than or equal to 0.03 Newtons and less than or equal to 3 Newtons.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Specifically, the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear can be 0.03N, 0.1N, 0.2N, 0.5N, 0.8N, 1.0N, 1.2N, 1.5N, 2.0N, 2.4N, 2.7N or 3.0N. The force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear can be any value between 0.1N and 2.7N; or, the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear can be any value between 0.2N and 2.4N; or, the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear can be any value between 0.5N and 2.0N; or, the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear can be any value between 0.8N and 1.5N; or, the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear can be any value between 1.0N and 1.2N.

[0041] If the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear is less than 0.03N, the force is too small, and the earphone 100 may not fit securely against the ear, resulting in unstable wearing, easy slippage or loosening, especially during vigorous exercise or rapid movement. The earphone 100 may fall off or shift, which not only affects the stability of wearing but also the sound quality, failing to achieve the desired sound effect. If the force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear exceeds 3N, the force is too large, which may cause excessive pressure on the earphone 100, and the wearer may feel discomfort or pain, affecting the wearing comfort.

[0042] The force exerted by the sound-emitting part 11 and / or the hook-shaped part 133 on the human ear is greater than or equal to 0.03N and less than or equal to 3N. The earphone 100 can maintain an appropriate force with the ear, which can ensure the stability of the earphone 100 while avoiding excessive pressure on the ear, ensuring wearing comfort and improving the wearing experience.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] As mentioned earlier, the width direction is... Figure 2 or Figure 3 The 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.

[0050] Please see Figure 4 and Figure 5In 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.

[0051] 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.

[0052] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, when the user wears the headphones 100, the back surface 113 is a flat surface, and the first included angle α1 between the back surface 113 and the sagittal plane of the human body is greater than or equal to 5° and less than or equal to 25°.

[0053] Specifically, the first included angle α1 can be 5°, 6°, 7°, 8°, 9°, 10°, 12°, 15°, 17°, 19°, 22°, or 25°. Preferably, the first included angle α1 is 6°. The first included angle α1 can be any value between 6° and 22°; or, the first included angle α1 can be any value between 7° and 19°; or, the first included angle α1 can be any value between 8° and 17°; or, the first included angle α1 can be any value between 9° and 15°; or, the first included angle α1 can be any value between 10° and 12°.

[0054] If the first included angle α1 is less than 5°, the angle between the back surface 113 of the earphone 100 and the sagittal plane of the human body is too small. This requires increasing the size between the back surface 113 and the sound outlet surface 111 of the earphone 100 to better adapt to the shape of the ear and ensure that the sound outlet 1111 can be inserted into the concha cavity. Increasing the size between the back surface 113 and the sound outlet surface 111 will result in a larger overall size of the earphone 100, affecting its portability when worn and potentially causing discomfort after wearing the earphone 100. In particular, a larger earphone 100 may cause pressure on the auricle area during wear.

[0055] If the first included angle α1 is greater than 25°, the angle between the back of the earphone 100 113 and the ear is too large, which may cause the sound output part 11 of the earphone 100 to form a large gap with the auricle. This will make the earphone 100 unstable when worn, and the sound output part 11 may press on the tragus, causing discomfort to the wearer. It may also affect the stability of the earphone 100, making it easy for the earphone 100 to slip or fall off during wear, reducing the comfort and stability of wearing.

[0056] Therefore, in this embodiment, the range of the first included angle α1 is greater than or equal to 5° and less than or equal to 25°. This can avoid the increase in the size of the earphone 100 and the discomfort caused by too small an included angle, and can also avoid the instability and pressure caused by too large an included angle. This ensures that the earphone 100 can fit comfortably in the ear while maintaining appropriate stability, avoiding discomfort during wearing and the problem of the earphone 100 falling off, and effectively improving the wearing experience and comfort.

[0057] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, when the user wears the headphones 100, the back surface 113 is curved, and the first included angle α1 between the tangent of the vertex of the projection of the back surface 113 in the first projection plane Pw and the sagittal plane of the human body is greater than or equal to 5° and less than or equal to 25°.

[0058] Specifically, the first included angle α1 can be 5°, 6°, 7°, 8°, 9°, 10°, 12°, 15°, 17°, 19°, 22°, or 25°. Preferably, the first included angle α1 is 6°. The first included angle α1 can be any value between 6° and 22°; or, the first included angle α1 can be any value between 7° and 19°; or, the first included angle α1 can be any value between 8° and 17°; or, the first included angle α1 can be any value between 9° and 15°; or, the first included angle α1 can be any value between 10° and 12°.

[0059] If the first included angle α1 is less than 5°, the angle is too small, which requires the headphone 100 to increase the size between the back surface 113 and the sound outlet surface 111 in order to better fit the shape of the ear and ensure that the sound outlet 1111 can be inserted into the concha cavity. Increasing the size between the back surface 113 and the sound outlet surface 111 will make the overall size of the headphone 100 larger, affecting the portability when wearing it, and may also cause discomfort after wearing the headphone 100, especially when the headphone 100 is large, it may cause pressure on the auricle area during wearing.

[0060] If the first included angle α1 is greater than 25°, the included angle is too large, which may cause the sound output part 11 of the earphone 100 to form a large gap with the auricle, thus making the earphone 100 unstable when worn. The sound output part 11 may press on the tragus, causing discomfort to the wearer and may also cause sound leakage.

[0061] Therefore, in this embodiment, the first included angle α1 being greater than or equal to 5° and less than or equal to 25° can avoid the increase in the size of the earphone 100 and the discomfort caused by too small an included angle, and can also avoid the instability and pressure caused by too large an included angle. It can also ensure that the sound outlet 1111 and the concha cavity are aligned, with a small gap, and it is not easy for sound to leak.

[0062] Please see Figure 4 and Figure 5 In some embodiments, the earphone 100 further includes a circuit board 30, a communication unit 40, and a battery 50. The circuit board 30 and the battery 50 are housed in a housing cavity 102. The communication unit 40 is disposed in the sound outlet 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 outlet surface 111.

[0063] 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.
