[0014] And / or, the angle between the tangent of the outer contour of the elastic connecting arm and the outer contour of the battery pack at their connection point is 75° to 105°.

[0016] And / or, the minimum straight-line distance between the sound-generating unit and the battery pack is 3.5mm to 6.5mm, wherein the first direction is perpendicular to the second direction.

[0017] In some embodiments, the sound-generating unit includes a housing and a speaker, the annular region and the sound-emitting region are the outer surfaces of the housing, an inner cavity is formed inside the housing, and the speaker is disposed in the inner cavity; the ear clip-on headphones include a circuit board, the circuit board is disposed in the inner cavity and located on the side of the speaker near the elastic connecting arm.

[0018] In some implementations, the volume of the battery pack is smaller than the volume of the sound-generating unit;

[0019] And / or, the elastic connecting arm arches in a first arc shape toward the first direction, and the sound-generating unit and the battery pack are spaced apart along the second direction; the ratio of the maximum dimension of the battery pack along the third direction to the maximum dimension of the sound-generating unit along the third direction is 0.5 to 2, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0036] This application provides an ear clip-on headphone 100.

[0037] Please see Figures 1 to 4 The ear clip-on headphones 100 include a sound unit 10, a battery pack 20, and a flexible connecting arm 30.

[0038] The sound-emitting unit 10 is provided with a sound outlet 10a, which is used to fit against the outside of the ear canal opening.

[0039] The battery pack 20 is placed behind the ear and is electrically connected to the sound unit 10.

[0040] The flexible connecting arm 30 connects the sound unit 10 and the battery pack 20. The flexible connecting arm 30 is in the shape of an arc and can deform under the action of external force so that the sound unit 10 and the battery pack 20 together clamp the auricle.

[0041] The outer surface of the sound-generating unit 10 includes an annular region 10b and a sound-emitting region 10c. One end of the annular region 10b is connected to the elastic connecting arm 30, and the other end extends in an arc shape away from the elastic connecting arm 30 to connect with the sound-emitting region 10c. The sound-emitting hole 10a is disposed in the sound-emitting region 10c, and a portion of the sound-emitting region 10c extends in an arc shape along the connection with the annular region 10b to the edge of the sound-emitting hole 10a.

[0042] The ear canal, also known as the external auditory canal, is located between the outer ear (auricle) and the middle ear, and is the passage from the outside of the ear to the eardrum. The ear canal serves as a pathway for sound conduction, transmitting sound waves to the eardrum so that the user can hear. The ear canal opening, also known as the external auditory canal opening or ear hole, is the entrance to the external auditory canal, located in the transition area between the auricle (outer ear) and the middle ear. It is where the ear canal begins. Sound enters the ear through the ear canal opening. As sound waves travel through the air to the ear canal opening, they are guided into the external auditory canal and ultimately transmitted to the eardrum, thus triggering the hearing process.

[0043] The sound-generating unit 10 is one of the core components of the ear clip-on headphones 100, used to convert electrical signals into sound. Exemplarily, the sound-generating unit 10 may include a speaker 12 or a driver, which may include a magnet, a voice coil, and a diaphragm. When an electric current passes through the voice coil, a changing magnetic field is generated. The magnetic field interacts with the magnet, causing the diaphragm to vibrate, thereby generating sound waves.

[0044] The speaker 12 can be a moving type, an electrostatic type, or a planar magnetic type, etc., and there are no restrictions here.

[0045] The sound outlet 10a is used as the sound output port of the sound generating unit 10. For example, the speaker 12 is positioned close to the sound outlet 10a to transmit the generated sound waves to the user's ear canal through the sound outlet 10a.

[0046] The sound outlet 10a is designed to fit against the outer side of the ear canal opening. This means that the sound outlet 10a is positioned close to the ear canal opening and fits against the outer edge of the ear canal opening, i.e., the sound outlet 10a can cover the outer side of the ear canal opening. In this way, the sound outlet 10a can be aligned with the ear canal opening, allowing sound to be effectively transmitted into the ear canal and reducing external noise interference. Therefore, the ear clip-on earphone 100 of this application embodiment has a semi-in-ear feature, which can reduce sound leakage and achieve noise reduction without compressing the ear canal.

[0047] It should be noted that the form of the sound outlet 10a is not limited. In some embodiments, the sound outlet 10a can be composed of multiple small holes. For example, the sound-emitting unit 10 includes a mesh plate with multiple small mesh holes. The sound outlet 10a is a combination of multiple small mesh holes.

[0048] The battery pack 20 provides power to the sound unit 10, enabling the clip-on headphones 100 to operate without a direct connection to an external power source. Exemplarily, the battery pack 20 may include one or more rechargeable batteries.

[0049] The battery pack 20 is placed behind the ear, which helps to balance the weight of the clip-on headphones 100, reduces pressure on the ears, and does not take up space in the ear canal, making them more comfortable to wear.

[0050] The flexible connecting arm 30 is used to connect the sound unit 10 and the battery pack 20 to form a stable structure, so that the sound unit 10 and the battery pack 20 can work together on the auricle to achieve stable wearing.

[0051] The flexible connecting arm 30 is arched, meaning it has a curved, upward-arching shape, similar to an arch or bow. For example, the flexible connecting arm 30 is generally C-shaped. This arched shape allows the flexible connecting arm 30 to deform, enabling the speaker unit 10 and battery pack 20 to apply moderate pressure to the ear, thus securing them firmly to the ear without feeling too tight or uncomfortable.

[0052] In this embodiment, the ear clip-on headphones 100 are stably worn by deforming the elastic connecting arm 30. That is, the wearing adjustment is achieved by the movement of the elastic connecting arm 30 relative to the sound unit 10 and the battery pack 20, which reduces the restriction on the sound unit 10 and the battery pack 20, and the structure of the ear clip-on headphones 100 can be relatively simple.

[0053] The annular region 10b extends in an arc shape, meaning that its cross-sectional area gradually increases in the direction away from the elastic connecting arm 30. This arc-shaped expansion also allows the angle between the elastic connecting arm 30 and the annular region 10b to form an arc angle. This allows the annular region 10b to fit snugly against the anti-helix when the ear clip-on earphone 100 is worn, increasing wearing stability. In other words, the annular region 10b can be formed into a streamlined, arc-shaped area, like a swan's neck.

[0054] Understandably, the antihelix is ​​a Y-shaped cartilaginous protrusion located inside the outer ear, near the opening of the ear canal.

[0055] The sound output area 10c extends in an arc shape along the connection with the annular area 10b to the edge of the sound output hole 10a. With the ear canal opening as a reference, the sound output area 10c extends in an arc shape towards the ear canal opening to the edge of the sound output hole 10a. There is an arc transition from this part to the edge of the sound output hole 10a. The sound output area 10c does not extend in a straight line to the sound output hole 10a, but has a contour that curves and gradually expands towards the ear canal opening. In this way, the sound output hole 10a can act as a protruding part and stably fit against the outside of the ear canal opening. The sound output hole 10a is located at the end of the arc-shaped expansion from the annular area 10b to the sound output area 10c, which helps to make the sound output hole 10a directly aligned with the ear canal opening and make the sound waves propagate more concentrated towards the ear canal opening.

[0056] It is understandable that in related technologies, the ear clip-on headphones have the sound unit placed far away from the ear canal opening to achieve open-back sound generation. This method has problems such as sound leakage and weak noise reduction. At the same time, the sound unit structure of ear clip-on headphones adopts a flat or simple curved surface design, which lacks consideration for the adaptation of the user's ear shape and affects wearing comfort.

[0057] The ear-clip earphone 100 provided in this embodiment has a sound outlet 10a fitted to the outside of the ear canal opening, and a sound-generating unit 10 positioned close to the ear canal opening. This allows the sound emitted by the sound-generating unit 10 to be concentrated and enter the ear canal opening via a shorter path, increasing the reliability of sound propagation, reducing sound leakage, and enhancing noise reduction. Furthermore, the annular area 10b and the sound outlet area 10c allow the shape of the sound-generating unit 10 to conform to the auricle, facilitating a more stable position of the sound-generating unit 10 within the auricle and ensuring effective alignment of the sound outlet 10a with the ear canal opening, thus increasing wearing stability. Therefore, only minor adjustments to the elastic connecting arm 30 are needed to achieve both semi-in-ear sound generation and secure clamping, resulting in high wearing reliability. This also enhances the aesthetic appeal of the ear-clip earphone 100.

[0058] In some embodiments, please refer to Figure 4 The elastic connecting arm 30 arches in a first arc shape toward the first direction. In the cross-section of the ear clip earphone 100 along the first direction, the inner contour line of the elastic connecting arm 30 includes a first curved line 30a, and the inner contour line of the annular region 10b includes a second curved line 10d for cooperating with the antihelix. The first curved line 30a and the second curved line 10d are curved curves in the same direction, and the first curved line 30a and the second curved line 10d are connected.

[0059] It is understandable that the first direction points to the arch of the elastic connecting arm 30, that is, in the first direction, the arch of the elastic connecting arm 30 is located at the highest point of the ear clip-on earphone 100 along the first direction. Simultaneously, the first direction can also be... Figure 4The outer contour of the annular region 10b extends in a parallel or approximately parallel direction. The elastic connecting arm 30 arches in an arc shape toward the first side of the first direction, that is, the elastic connecting arm 30 arches in an arc shape away from the ear canal opening along the first direction.

[0060] The cross-section of the ear clip-on earphone 100 along the first direction is a cross-sectional view obtained by cutting the ear clip-on earphone 100 along the first direction. Here, the inner contour line of the elastic connecting arm 30 refers to the inner edge line or boundary line of the elastic connecting arm 30. Specifically, the elastic connecting arm 30 is roughly C-shaped, the inner contour line of the elastic connecting arm 30 is the boundary line closer to the center of the C-shape, and the outer contour line of the elastic connecting arm 30 is the outer edge line or boundary line, which is further away from the center of the C-shape.

[0061] The inner contour line of the annular region 10b is also an inward-facing edge or boundary line. Here, it can be an edge line closer to the side of the battery pack 20. The inner contour line of the annular region 10b is oriented towards the antihelix. The outer contour line of the annular region 10b is an outward-facing edge or boundary line. The outer contour line of the annular region 10b is closer to the ear canal opening.

[0062] The first bending line 30a and the second bending line 10d are bending curves in the same direction. This means that the first bending line 30a and the second bending line 10d are curves in the same direction, but it does not mean that the first bending line 30a and the second bending line 10d are in the same direction.

[0063] Here, the first curved line 30a represents a protrusion or depression in the same direction within the inner contour of the elastic connecting arm 30. The curvature of each point on the first curved line 30a can be the same. The second curved line 10d represents a protrusion or depression in the same direction within the inner contour of the annular region 10b. The curvature of each point on the second curved line 10d can be the same.

[0064] For example, please refer to Figure 4 The first curved line 30a faces the battery pack 20 and is recessed outward relative to the battery pack 20. The second curved line 10d faces the elastic connecting arm 30 and is recessed downward relative to the elastic connecting arm 30.

[0065] Please see Figure 4 The angle α between the tangent of the first curved line 30a and the tangent of the second curved line 10d is 30° to 90°, that is, 30°≤α≤90°, for example, 30°, 35°, 40°, 45°, 48°, 50°, 55°, 60°, 64°, 69°, 75°, 83°, 90°, etc.

[0066] It should be noted that the angle between the tangents of the first curved line 30a and the second curved line 10d is 30° to 90°, which means that the angle between the tangent at any point of the first curved line 30a and the tangent at any point of the second curved line 10d is 30° to 90°.

[0067] The angle α between the tangent of the first curved line 30a and the tangent of the second curved line 10d is set such that the second curved line 10d can be adapted to the antihelix, the annular area 10b can be adapted to the antihelix, and the first curved line 30a and the second curved line 10d can be connected to form a notch 10f. The notch 10f cooperates with the antihelix to form a snap-fit ​​effect, thereby constraining the sound unit 10 through the tragus and the antihelix, increasing the wearing stability of the ear clip-on earphone 100, and keeping the sound outlet 10a aligned with the ear canal opening.

[0068] Understandably, when α > 90°, the first curvature 30a is relatively far from the antihelix, and the curvature of the notch 10f is relatively large. It is not possible to form a stable fit between the notch 10f and the antihelix, which is not conducive to wearing stability. At the same time, it is not convenient to miniaturize the overall size of the ear clip-on earphone 100. When α < 30°, the curvature of the notch 10f is relatively small, which is easy to put pressure on the ear and is not conducive to wearing comfort.

[0069] In this embodiment, the angle between the tangent of the first curved line 30a and the tangent of the second curved line 10d can reduce pressure on the ear while forming a stable fit with the antihelix, increasing wearing stability and comfort. At the same time, it can also reduce the overall size of the ear clip-on earphone 100, facilitating miniaturization design.

[0070] In some embodiments, the angle between the tangent of the first curved line 30a and the tangent of the second curved line 10d is 45° to 75°, for example, 45°, 47°, 50°, 53°, 55°, 60°, 64°, 68°, 72°, 75°, etc.

[0071] In this embodiment, the angle between the tangent of the first curved line 30a and the tangent of the second curved line 10d is more suitable, which makes it easier to effectively fit the shape of the ear, further increasing the wearing stability of the sound unit 10 and improving the wearing stability and comfort of the ear clip headphones 100.

[0072] In some embodiments, please refer to Figure 4 The inner contour of the annular region 10b also includes a third curved line 10e, which is connected to the second curved line 10d and their curvatures are opposite. The outer contour of the annular region 10b is a curved curve in the same direction, and the angle between the outer contour of the annular region 10b and the outer contour of the elastic connecting arm 30 is less than 1°.

[0073] The third bend line 10e is connected to the end of the second bend line 10d that is away from the first bend line 30a.

[0074] The curvature of the third curved line 10e is opposite to that of the second curved line 10d, meaning that the bending directions of the third curved line 10e and the second curved line 10d are opposite. For example, the second curved line 10d faces the elastic connecting arm 30 and is concave downwards relative to the elastic connecting arm 30. The third curved line 10e, on the other hand, convexes upwards relative to the elastic connecting arm 30.

[0075] Thus, there will be a change in the direction of the bend between the second bend line 10d and the third bend line 10e, so as to better fit and conform to the auricle and increase wearing comfort.

[0076] For example, the first curved line 30a, the second curved line 10d, the third curved line 10e to the sound output area 10c can roughly form an S-shaped area, which can increase wearing stability and comfort, as well as increase the aesthetic appearance of the clip-on headphones 100.

[0077] The outer contour of the annular region 10b is a single-direction curved curve, meaning the outer contour of the annular region 10b bends in the same direction without any change in the direction of curvature. For example, the curvature is the same at all points along the outer contour of the annular region 10b. The angle between the outer contour of the annular region 10b and the outer contour of the elastic connecting arm 30 is less than 1°, meaning the ear clip-on earphone 100 forms a continuous, flat curved surface at both points. The outer contour of the annular region 10b and the outer contour of the elastic connecting arm 30 smoothly connect and transition, and their bending directions are the same at the connection point. This facilitates a close fit with the tragus, keeping the sound outlet 10a aligned with the ear canal opening and increasing the reliability of sound propagation.

[0078] In some embodiments, please refer to Figure 4 The inner contour of the elastic connecting arm 30 includes a fourth curved line 30b, the curvature of which is opposite to that of the first curved line 30a, and the angle between the fourth curved line 30b and the inner contour of the battery pack 20 is less than 1°.

[0079] The curvature of the fourth curved line 30b is opposite to that of the first curved line 30a, meaning that the bending direction of the fourth curved line 30b is opposite to that of the first curved line 30a. Taking the elastic connecting arm 30 as a C-shape as an example, the third curved line 10e and the fourth curved line 30b can each occupy half of the C-shape, and the highest point of the C-shape arch is the boundary between the two.

[0080] Understandably, both the fourth curved line 30b and the inner contour line of the battery pack 20 are parts that need to contact the back of the ear. The angle between the fourth curved line 30b and the inner contour line of the battery pack 20 is less than 1°, meaning that the ear clip-on headphones form a continuous flat curved surface at both points, which can better fit the ear. The battery pack 20 will not protrude or sink relative to the elastic connecting arm 30 on the side near the ear, resulting in a large contact area with the ear and no pressure on the ear, thus providing high wearing stability and comfort.

[0081] In some embodiments, please refer to Figure 4 The angle θ between the tangents of the outer contour of the elastic connecting arm 30 and the outer contour of the battery pack 20 at their connection point is 75° to 105°, i.e., 75°≤θ≤105°, for example, 75°, 80°, 85°, 90°, 92°, 95°, 96°, 100°, 105°, etc.

[0082] In this embodiment, the outer contour of the battery pack 20 protrudes away from the ear relative to the outer contour of the elastic connecting arm 30. This allows the battery pack 20 to have enough space to accommodate the battery while ensuring the clamping force of the battery pack 20.

[0083] In some embodiments, the elastic connecting arm 30 is arched in a first direction, and the sound-generating unit 10 and the battery pack 20 are spaced apart along a second direction. The first direction is perpendicular to the second direction.

[0084] Please see Figure 4 The angle β between the perpendicular bisector of the sound hole 10a and the second direction is 50° to 90°, i.e., 50°≤β≤90°, for example, 50°, 55°, 60°, 63°, 72°, 75°, 78°, 80°, 81°, 84°, 88°, 90°, etc.

[0085] The sound-emitting unit 10 and the battery pack 20 are spaced apart along the second direction, that is, the sound-emitting unit 10 and the battery pack 20 are spaced apart in the second direction, so as to form a clamping effect on the ear.

[0086] The perpendicular bisector of the sound hole 10a refers to the straight line passing through the center point of the sound hole 10a.

[0087] In this embodiment, the angle between the vertical line of the sound outlet 10a and the second direction is set so that the position of the sound outlet 10a relative to the battery pack 20 and the sound-generating unit 10 is appropriate, so that the sound outlet 10a can be in the optimal position aligned with the ear canal opening, and the sound outlet 10a can cover the outer side of the ear canal opening as much as possible, so as to reduce sound leakage, increase noise reduction effect, improve sound propagation effect, and ensure sound quality and volume.

[0088] The second direction can be along Figure 4The horizontal direction shown can be the direction of the minimum straight-line distance between the sound-generating unit 10 and the battery pack 20.

[0089] In some embodiments, please refer to Figure 4 The minimum straight-line distance D between the sound-emitting unit 10 and the battery pack 20 is 3.5mm to 6.5mm, that is, 3.5mm≤D≤6.5mm, for example, 3.5mm, 3.6mm, 3.9mm, 4mm, 4.2mm, 3.4mm, 4.5mm, 4.8mm, 5mm, 5.1mm, 5.3mm, 5.7mm, 6mm, 6.5mm, etc.

[0090] In this embodiment, the distance between the sound-generating unit 10 and the battery pack 20 is neither too large nor too small, which can reduce pressure on the ears while forming a stable clamping force, thereby increasing the wearing stability and comfort of the ear clip headphones 100.

[0091] In some embodiments, please refer to Figure 4 The sound-generating unit 10 includes a housing 11 and a speaker 12. The annular region 10b and the sound-emitting region 10c are the outer surfaces of the housing 11. An inner cavity 11a is formed inside the housing 11, and the speaker 12 is disposed in the inner cavity 11a. The ear clip-on headphones 100 include a circuit board 40, which is disposed in the inner cavity 11a and located on the side of the speaker 12 near the elastic connecting arm 30.

[0092] The circuit board 40 is used to process audio signals. At the same time, the circuit board 40 can also perform user interaction, such as processing user input commands, such as adjusting volume, switching songs or answering phone calls through physical buttons or touch sensing. For example, the housing 11 can be provided with a button area corresponding to the circuit board 40.

[0093] Battery pack 20 can power circuit board 40.

[0094] The speaker 12 receives electrical signals from the circuit board 40 and converts them into sound waves so that the user can hear music or other audio content.

[0095] In this embodiment, the circuit board 40 is disposed in the inner cavity 11a, that is, in the sound unit 10, which can make full use of the space expanded by the annular area 10b of the sound unit 10, so that the battery pack 20 can be designed to be as small as possible to reduce the overall volume of the ear clip-on headphones 100.

[0096] Understandably, in related technologies, the circuit board is located inside the battery pack, resulting in a relatively large battery pack. In this embodiment, however, the circuit board is located within the sound-generating unit, making the earbud structure more compact and rationally laid out.

[0097] In some embodiments, the battery pack 20 is smaller than the volume of the sound-generating unit 10. This reduces the need for a large battery pack 20, decreasing pressure on the ears, and also makes the clip-on earphone 100 more aesthetically pleasing.

[0098] In some embodiments, please refer to Figure 3 The elastic connecting arm 30 is arched in the first direction, and the sound unit 10 and the battery pack 20 are spaced apart along the second direction. The ratio of the maximum dimension d1 of the battery pack 20 along the third direction to the maximum dimension d2 of the sound unit 10 along the third direction is 0.5 to 2, that is, 0.5≤d1 / d2≤2, for example, 0.5, 0.6, 0.75, 0.8, 1, 1.2, 1.4, 1.6, 1.8, 2, etc.

[0099] Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0100] Here, the third direction can be the vertical direction relative to the user after the ear clip-on headphones 100 are worn.

[0101] In this embodiment, the battery pack 20 is sized along a third direction, which can provide a stable clamping effect on the ear while satisfying the internal battery stacking requirements, and the size is not too large to cause pressure or affect the aesthetic appearance.

[0102] In some embodiments, the elastic connecting arm 30 includes a connecting wire and a wrapping layer. The connecting wire connects the battery pack 20 and the sound generating unit 10. The wrapping layer has a cavity, and the connecting wire is located in the cavity. The wrapping layer is a soft structure.

[0103] In this embodiment, the battery pack 20 and the sound-generating unit 10 are connected by a connecting steel wire. The wrapping layer is wrapped around the connecting steel wire, which can achieve both elastic clamping and contact with the ear through the soft wrapping layer, making it more comfortable to wear. When wearing, the wrapping layer can face the front of the ear and contact the ear.

[0104] The covering layer has a soft structure, which allows for easy deformation and reduces pressure on the ear. For example, the covering layer can be formed as a soft gel.

[0105] Of course, the cavity can also provide a channel for the cable, allowing the cable to run inside without affecting the aesthetics of the clip-on headphones 100.

[0106] In some embodiments, please refer to Figure 1 The battery pack 20 has a first tab region 20a, at least a portion of which is formed as a soft structure.

[0107] It is understood that the first ear-contact region 20a is the part of the battery pack 20 that is in contact with the ear. For example, the inner contour line of the battery pack 20 is located in the first ear-contact region 20a.

[0108] At least a portion of the first ear-attached area 20a is formed as a soft structure, that is, it has flexible deformation characteristics, which makes it easier to reduce pressure on the ear and increase wearing comfort when wearing.

[0109] It should be noted that at least a portion of the first auricle region 20a is formed as a soft structure. This can be that the entire first auricle region 20a is formed as a soft structure, or that the first auricle region 20a is formed as a soft structure covering a hard structure.

[0110] Please see Figure 1 The sound-emitting unit 10 has a second ear-mounted region 10g, which covers the sound-emitting region 10c or covers at least a portion of the sound-emitting region 10c and the annular region 10b. At least a portion of the second ear-mounted region 10g is a soft structure.

[0111] Understandably, the second ear-contact area 10g is the part of the sound-generating unit 10 that comes into contact with the ear.

[0112] The second ear-mounted area 10g covering at least a portion of the sound output area 10c or the annular area 10b means that the second ear-mounted area 10g may only cover the sound output area 10c, in which case the annular area 10b may not be a soft structure, thus increasing the decorative effect; the second ear-mounted area 10g may also cover at least a portion of the sound output area 10c and the annular area 10b, in which case the pressure on the ear can be further reduced, increasing wearing comfort.

[0113] At least a portion of the second ear-attaching area 10g is formed as a soft structure, that is, it has flexible deformation characteristics, which makes it easier to reduce pressure on the ear and increase wearing comfort when wearing.

[0114] It should be noted that at least a portion of the second auricular region 10g is formed as a soft structure. This can be that the entire second auricular region 10g is formed as a soft structure, or that the second auricular region 10g is formed as a soft structure covering a hard structure.

[0115] In some embodiments, the first ear-attachment region 20a and / or the second ear-attachment region 10g are constructed as follows: soft rubber overlaying hard rubber in a two-color injection molding process.

[0116] Two-color injection molding is a process that combines two materials of different hardness or type through a single molding process.

[0117] In this embodiment, the design of soft rubber covering hard rubber can provide structural support through the hard rubber while ensuring shape stability, and the soft rubber provides a softer and more comfortable touch when in contact with the skin. At the same time, the two-color injection molding method can also improve production efficiency and reduce assembly steps.
