[0033] 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.

[0034] 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.

[0035] 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.

[0036] Please see Figures 2 to 5 The earphone 100 includes a housing 10. The housing 10 includes a sound-emitting part 11 and an ear clip part 13. The sound-emitting part 11 is provided with a speaker 20. The ear clip part 13 includes a connecting part 131 and a hook-shaped part 133. The connecting part 131 is connected 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 in the user's concha cavity. The ear clip part 13 extends from the antihelix and the helix to the space between the auricle and the head.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] As before, 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.

[0049] Please see Figure 6In some embodiments, within the first projection plane Pw, the centroid of the sound outlet 1111 has a projection center C, and the protrusion BP and the projection center C have a first distance D1 in the first direction A1. The first distance D1 is greater than or equal to 20mm and less than or equal to 35mm.

[0050] Wherein, the centroid of the sound outlet 1111 is the geometric center of the sound outlet 1111. Specifically, the first distance D1 can be: 20mm, 22mm, 24mm, 26mm, 27mm, 28mm, 30mm, 32mm, 33mm, or 35mm. Preferably, the first distance D1 is 27.2mm. The first distance D1 can be any value between 22mm and 33mm; or, the first distance D1 can be any value between 24mm and 32mm; or, the first distance D1 can be any value between 26mm and 31mm; or, the first distance D1 can be any value between 27mm and 30mm; or, the first distance D1 can be any value between 27.5mm and 28mm.

[0051] It is understandable that there is a certain distance between the concha and the helix. When the user wears the headphones 100, the sound output part 11 is at least partially housed in the concha, the sound output hole 1111 is aligned with the concha, and the ear clip 13 extends around the helix to the space between the auricle and the head, and at least partially abuts against the back of the auricle 113. Therefore, the first distance D1 needs to be adapted to the distance between the concha and the helix.

[0052] If the first distance D1 is less than 20mm, then the first distance D1 is too small, and the ear clip 13 is difficult to fix the earphone 100 after it surrounds the helix when the sound outlet 11 is at least partially housed in the concha cavity. In addition, the first distance D1 is too small, which makes the earphone 100 contact the auricle too tightly, which can easily cause pressure on the ear and cause discomfort to the user.

[0053] If the first distance D1 is greater than 35mm, then the first distance D1 is too large. When the sound output part 11 is at least partially housed in the concha cavity, the distance between the ear clip part 13 and the auricle is too far. The contact area between the earphone 100 and the auricle is reduced, and the ear clip cannot fix the auricle. When wearing the earphone, the earphone 100 is easy to slide or fall off, thus affecting the stability of wearing.

[0054] Therefore, in this embodiment, the first distance D1 is between 20mm and 35mm, ensuring that the contact between the ear clip 13 and the auricle is neither too tight nor too loose. At this time, the earphone 100 can be securely fixed to the ear, ensuring both wearing comfort and optimizing the contact surface between the earphone 100 and the auricle, effectively preventing the earphone 100 from slipping or falling off, and improving the stability of the earphone 100.

[0055] Please see Figure 6In some embodiments, in the second direction A2, there is a second distance D2 between the projection center C and the vertex of the projection of the back surface 113 in the first projection plane Pw, and the ratio between the first distance D1 and the second distance D2 is greater than or equal to 1.4 and less than or equal to 1.8.

[0056] Specifically, the ratio between the first distance D1 and the second distance D2 can be: 1.4, 1.45, 1.5, 1.55, 1.6, 1.65, 1.7, 1.75, or 1.8. Preferably, the ratio between the first distance D1 and the second distance D2 is 1.5.

[0057] Understandably, the second distance D2 represents the distance from the centroid of the sound outlet 1111 to the back 113 of the earphone 100, which can characterize the size of the earphone 100 in the cross-section of the human body when the user is wearing the earphone 100.

[0058] If the ratio between the first distance D1 and the second distance D2 is less than 1.4, then the first distance D1 is too large. When the sound output part 11 is at least partially housed in the concha cavity, the distance between the ear clip part 13 and the auricle is too far. The contact area between the earphone 100 and the auricle is reduced, and the ear clip cannot fix the auricle. When wearing the earphone, the earphone 100 is easy to slide or fall off, thus affecting the stability of wearing.

[0059] If the ratio between the first distance D1 and the second distance D2 is greater than 1.8, then the second distance D2 is too large, the size of the sound output part 11 in the second direction A2 is too large, and the back 113 of the sound output part 11 is too far from the human body, which increases the risk of the earphone 100 falling off due to external impact or bump.

[0060] The ratio between the second distance D2 and the first distance D1 is greater than or equal to 1.4 and less than or equal to 1.8. The contact between the earphone 100 and the auricle is neither too tight nor too loose, so that it can be stably fixed in the ear when worn, preventing slippage and improving wearing comfort and stability.

[0061] Please see Figure 6 In some embodiments, a reference line RE is a straight line parallel to the second direction A2 and passing through the vertex of the projection of the sound-emitting surface 111 into the first projection plane Pw; in the first direction A1, there is a third distance D3 between the projection center C and the reference line RE, and the ratio between the third distance D3 and the first distance D1 is greater than or equal to 0.1 and less than or equal to 0.35.

[0062] Specifically, the ratio between the third distance D3 and the first distance D1 can be: 0.1, 0.12, 0.14, 0.16, 0.17, 0.18, 0.2, 0.25, 0.3, or 0.35. Preferably, the ratio between the third distance D3 and the first distance D1 is 0.17. It can be understood that the third distance D3 represents the distance between the projection center C of the centroid of the sound outlet 1111 and the reference line RE, characterizing the degree of offset of the position of the sound outlet 1111 within the sound outlet 11 relative to the reference line RE. When a user wears the headphones 100, the third distance D3 affects the alignment between the sound outlet 1111 and the concha cavity, thereby affecting the wearing stability and sound quality performance of the headphones 100.

[0063] If the ratio of the third distance D3 to the first distance D1 is less than 0.1, then the first distance D1 is too large. In this case, although the sound output part 11 is at least partially accommodated in the concha, the distance between the ear clip part 13 and the auricle is too far, resulting in a reduction in the contact area between the earphone 100 and the auricle. Since the ear clip cannot effectively provide sufficient support for the auricle, the earphone 100 is prone to slipping or falling off when worn, thereby affecting the alignment of the sound output hole 1111 with the concha and resulting in poor sound output.

[0064] If the ratio of the third distance D3 to the first distance D1 is greater than 0.35, then the third distance D3 is relatively too large, and the position of the sound outlet 1111 is offset too far from the reference line RE, making it difficult for the sound outlet 1111 to be properly aligned with the concha. In this case, the sound quality of the headphone 100 may be affected, with significant sound loss during propagation.

[0065] The ratio between the third distance D3 and the first distance D1 is greater than or equal to 0.1 and less than or equal to 0.35mm. This ensures that the contact area between the earphone 100 and the auricle is moderate, the ear clip effectively provides sufficient support for the auricle, improves the wearing stability, and also ensures that the sound outlet 1111 is well aligned with the concha cavity, resulting in good sound output.

[0066] Please see Figure 4 , Figure 5 and Figure 7 In some embodiments, when the user wears the headphones 100, the first included angle α1 between the center line CL of the sound outlet 1111 and the sagittal plane of the human body is greater than or equal to 57° and less than or equal to 63°.

[0067] Specifically, the first included angle α1 can be 30°, 33°, 35°, 41°, 44°, 49°, 54°, 58°, 67°, 73°, 79°, or 90°. It is understandable that the setting of the first included angle α1 relates to the alignment of the sound propagation direction with the ear canal when the earphone 100 is worn. The first included angle α1 can be any value between 33° and 79°; or, the first included angle α1 can be any value between 35° and 73°; or, the first included angle α1 can be any value between 41° and 67°; or, the first included angle α1 can be any value between 44° and 58°; or, the first included angle α1 can be any value between 49° and 54°.

[0068] If the first included angle α1 is less than 57°, the center line CL of the sound outlet 1111 is too close to the sagittal plane, the connection angle between the sound direction of the sound outlet 1111 and the concha cavity is not ideal, the angle at which the sound is transmitted to the concha cavity is too large, which may cause the sound to be unable to be effectively introduced into the external auditory canal, affecting the transmission of sound effects.

[0069] If the first included angle α1 is greater than 63°, the angle between the center line CL of the sound outlet 1111 and the sagittal plane is too large, and the angle between the direction of sound propagation and the concha cavity is too small, causing the sound to easily escape from the concha cavity and fail to be transmitted to the external auditory canal, resulting in sound diffusion, distortion, or blurred sound quality.

[0070] The first included angle α1 is between 57° and 63°, which ensures that the sound outlet 1111 forms a suitable angle with the concha cavity, so that the sound can enter the external auditory canal more directly and match the natural shape of the external auditory canal. This not only improves the sound transmission efficiency, but also reduces the loss of sound during the propagation process, ensuring clearer sound quality.

[0071] Please see Figure 2 Figure 3 and Figure 6 In some embodiments, the second included angle α2 between the second direction A2 and the center line CL is greater than or equal to 42° and less than or equal to 53°.

[0072] Specifically, the second included angle α2 can be 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, or 53°. If the second included angle α2 is zero, i.e., the reference line RE is parallel to the coronal plane, the dimensional design of the earphone 100 in the coronal plane direction must take into account the space between the concha and the helix to ensure that the sound outlet 1111 is aligned with the concha and that the earphone 100 can provide a stable wearing effect around the helix. The second included angle α2 can be any value between 43° and 52°; or, the second included angle α2 can be any value between 44° and 51°; or, the second included angle α2 can be any value between 45° and 50°; or, the second included angle α2 can be any value between 46° and 49°; or, the second included angle α2 can be any value between 47° and 48°.

[0073] If the second included angle α2 is less than 42°, even if the sound outlet 1111 is aligned with the concha cavity, the earphone 100 will have difficulty forming a good contact with the helix, resulting in the earphone 100 being unstable, easy to loosen, and having a poor wearing effect. The looseness of the earphone 100 will cause the sound propagation direction to be inconsistent, affecting the clarity and penetration of the sound quality.

[0074] If the second included angle α2 is greater than 53°, although the sound hole 1111 may still be aligned with the concha cavity, the excessive deviation will cause the sound to diffuse during propagation, resulting in sound quality distortion, blurry sound or lack of clarity. At the same time, the contact area between the earphone 100 and the auricle will be reduced, making it unstable to wear and easy to slip or loosen.

[0075] If the second included angle α2 is greater than or equal to 42° and less than or equal to 53°, the sound hole 1111 can be aligned with the concha cavity, thereby improving the sound quality and preventing the earphone 100 from slipping or coming loose during wear, ensuring the stability and comfort of wearing.

[0076] 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.

[0077] 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.
