An ear clip type earphone

Abstract

This application provides an ear-clip earphone, including a sound-generating unit, a battery pack, an adjustment component, and a connecting arm. The adjustment component has an adjustment space extending along a first direction and includes a first adjustment member connected to the sound-generating unit with no relative movement between them. The connecting arm connects the adjustment component and the battery pack. The first adjustment member can move relative to the connecting arm along the first direction through the adjustment space, thereby driving the sound-generating unit to move within the concha. The ear-clip earphone provided in this application allows the first adjustment member to move the sound-generating unit relative to the connecting arm, adjusting the relative position of the sound-generating unit within the concha. This allows the sound-generating unit to be positioned closer to or further away from the ear canal opening, thus enabling switching between open-ear sound generation away from the ear canal opening and semi-in-ear sound generation entering the ear canal opening. Simultaneously, it reduces sound leakage and noise reduction, adapts to different ear sizes, increases wearing comfort, and provides high adaptability.

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a clip-on headphone. Background Technology

[0002] Headphones are devices that fit around, on, or inside the ear and radiate sound energy into the ear canal. Clip-on headphones gently clamp the ear to maintain the position of the headphones without completely blocking the ear, allowing users to hear ambient sounds. However, clip-on headphones suffer from sound leakage, weak noise cancellation, and a limited clamping angle, making them unsuitable for different ear sizes. Summary of the Invention

[0003] In view of this, the present application aims to provide an ear clip-on earphone that, through a first adjustment member driving the movement of the sound-producing unit, provides the user with the option to switch between open-ear sound production away from the ear canal opening and semi-in-ear sound production entering the ear canal opening, thereby improving wearing comfort.

[0005] The sound-producing unit is designed for placement in the concha cavity;

[0006] A battery pack for placement behind the ear, the battery pack being electrically connected to the sound-generating unit;

[0007] An adjustment assembly having an adjustment space extending along a first direction, the adjustment assembly including a first adjustment member connected to the sound-generating unit and the two having no relative movement;

[0008] A connecting arm connects the adjustment assembly to the battery pack, so that the sound-generating unit and the battery pack can together clamp the auricle;

[0009] The first adjustment member can move relative to the connecting arm in a first direction through the adjustment space to drive the sound-generating unit to move in the concha cavity, thereby increasing or decreasing the distance between the center of the sound-generating unit and the center of the ear canal opening.

[0010] In some embodiments, the connecting arm includes a first segment and a second segment connected to each other, the first segment being connected to the adjustment assembly at an end away from the second segment, the first segment extending along the first direction, and the second segment extending and bending from the end of the first segment away from the adjustment assembly toward the battery pack and being connected to the battery pack.

[0011] In some implementations, the first adjusting member defines the adjusting space, or the first adjusting member passes through the adjusting space and moves within the adjusting space along the first direction.

[0012] In some implementations, the adjustment assembly further includes a second adjustment member, the adjustment space extends through the second adjustment member along the thickness direction, the first adjustment member passes through the adjustment space, the connecting arm is connected to the end of the second adjustment member away from the sound-generating unit and is located outside the adjustment space, and there is no relative movement between the connecting arm and the second adjustment member.

[0013] In some embodiments, the first adjusting member includes a slider, the adjusting space is formed as a slide rail, and the slider slides in conjunction with the slide rail.

[0014] In some implementations, the slide rail is formed as a continuous closed structure to stop and limit the movement of the slider within the slide rail.

[0015] In some implementations, the first adjusting member and the second adjusting member are separate structures, and / or the first adjusting member and the second adjusting member are rigid structures.

[0016] In some implementations, the connecting arm is a rigid structure or the connecting arm is a flexible structure;

[0017] The connecting arm has a wire passage, and the ear clip-on earphone includes a connecting wire. One end of the connecting wire is connected to the battery pack, and the other end of the connecting wire passes through the wire passage, exits the connecting arm, and is electrically connected to the sound-generating unit.

[0018] In some embodiments, at least a portion of the first adjusting member is hollow to define the adjusting space, a portion of the connecting arm passes through the adjusting space, and the adjusting space is movable relative to the connecting arm to increase or decrease the size of the portion of the connecting arm outside the adjusting space.

[0019] In some embodiments, one of the first adjusting member and the connecting arm has a locking structure, and the other has a locking position for locking engagement with the locking structure, which is capable of disengaging from the current locking position and inserting into another locking position during movement of the first adjusting member relative to the connecting arm.

[0020] In some embodiments, the locking position includes a recess in the connecting arm, and the locking structure includes a bead protruding from the inner surface of the adjustment space, the bead being inserted into the recess.

[0024] In some implementations, the angle between the first direction and the reference line is 30° to 60°, wherein the reference line is a straight line passing through the center of the sound-generating unit and parallel to the direction of gravity.

[0025] In some implementations, the shortest straight-line distance between the sound-generating unit and the battery pack is 3mm to 15mm.

[0026] The ear-clip headphones provided in this application embodiment use a first adjusting member to move the sound-producing unit relative to the connecting arm, thereby adjusting the relative position of the sound-producing unit within the concha cavity. This allows the sound-producing unit to be positioned closer to or further away from the ear canal opening, enabling switching between open-ear sound emission away from the ear canal opening and semi-in-ear sound emission closer to the ear canal opening. Simultaneously, it reduces sound leakage and noise reduction capabilities, and adapts to different ear sizes, increasing wearing comfort. Users can adjust the wearing comfort and optimize the acoustic path according to their needs, making the ear-clip headphones highly flexible in their fit. The adjustable space increases the directional movement of the first adjusting member, providing a standardized adjustment mechanism that facilitates production and maintenance, while also reducing ear injury during movement.

[0042] This application provides an ear clip-on earphone 1.

[0043] Please see Figures 1 to 8 The ear clip-on headphones include a sound unit 10, a battery pack 11, a connecting arm 12, and an adjustment assembly 13.

[0044] The sound-producing unit 10 is placed in the concha cavity 2a.

[0045] The battery pack 11 is placed behind the ear and is electrically connected to the sound unit 10.

[0046] The adjustment assembly 13 has an adjustment space 13a extending along a first direction. The adjustment assembly 13 includes a first adjustment member 131, which is connected to the sound-generating unit 10 and the two do not move relative to each other.

[0047] The connecting arm 12 connects the adjustment assembly 13 to the battery pack 11 so that the sound unit 10 and the battery pack 11 can together clamp the auricle.

[0048] The first adjustment member 131 can move relative to the connecting arm 12 in the first direction through the adjustment space 13a to drive the sound-generating unit 10 to move in the concha cavity 2a, thereby increasing or decreasing the distance between the center of the sound-generating unit 10 and the center of the ear canal opening 2b.

[0049] The concha 2a, also known as the auricular cavity or auricular depression, is part of the outer ear. Specifically, it refers to a concave area on the auricle (the cartilaginous part of the outer ear) near the center of the ear 2. It is located between the crus of the helix and the antihelix and is a relatively open space. The concha 2a is a prominent anatomical landmark of the auricle and plays a certain acoustic role in the structure of the ear, helping to capture and guide sound into the ear canal.

[0050] The sound-generating unit 10 is one of the core components of the ear clip-on headphones 1, used to convert electrical signals into sound. The sound-generating unit 10 may include a speaker or a driver, which may include a magnet, a voice coil, and a diaphragm. When 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.

[0051] The specific structure of the sound-generating unit 10 is not limited; it can be a moving coil type, an electrostatic type, or a planar magnetic type, etc., and there are no restrictions here.

[0052] The shape of the sound-emitting unit 10 is not limited. For example, the sound-emitting unit 10 may be generally circular, elliptical or square, etc., without limitation.

[0053] The sound-generating unit 10 is located in the concha cavity 2a, which can reduce the pressure on the inside of the ear canal caused by inserting the sound-generating unit 10 into the ear canal and reduce the discomfort caused by wearing it for a long time. At the same time, the concha cavity 2a is relatively close to the ear canal opening 2b, which facilitates the transmission of audio signals from the sound-generating unit 10 to the eardrum.

[0054] The battery pack 11 provides power to the sound unit 10, enabling the clip-on headphones 1 to operate without a direct connection to an external power source. Exemplarily, the battery pack 11 may include one or more rechargeable batteries.

[0055] The battery pack 11 is placed behind the ear, which helps to balance the weight of the ear clip-on headphones 1, reduces pressure on the ears, and does not take up space in the ear canal, making them more comfortable to wear.

[0056] The connecting arm 12 is used to connect the adjustment component 13 and the battery pack 11 to form a stable structure, so that the sound unit 10 and the battery pack 11 can work together on the auricle to achieve stable wearing.

[0057] There is no relative movement between the first adjusting member 131 and the sound generating unit 10. This means that the sound generating unit 10 is fixedly connected to the first adjusting member 131, and the sound generating unit 10 and the first adjusting member 131 are relatively stationary. When the first adjusting member 131 is stationary, the sound generating unit 10 also remains stationary. When the first adjusting member 131 moves, the sound generating unit 10 can also move with the first adjusting member 131.

[0058] The connection method between the sound-generating unit 10 and the first adjusting member 131 is not limited; it can be snap-fit, glued, etc., and no restrictions are imposed here.

[0059] It should be noted that the first adjusting member 131 moves relative to the connecting arm 12 in the first direction through the adjusting space 13a. Here, the adjusting space 13a and the first adjusting member 131 may or may not move relative to each other. That is, the first adjusting member 131 may be connected to the adjusting space 13a, and the first adjusting member 131 may move relative to the connecting arm 12 in the first direction within the adjusting space 13a. In this case, only the first adjusting member 131 moves, and the connecting arm 12 and the adjusting space 13a do not move relative to each other. Alternatively, the first adjusting member 131 may be connected to the connecting arm 12 through the adjusting space 13a. When the first adjusting member 131 moves, it drives the adjusting space 13a, thereby achieving relative movement with the connecting arm 12.

[0060] It is understood that the connecting arm 12 connects the adjustment assembly 13 and the battery pack 11. The connecting arm 12 can be connected to the first adjustment member 131, or it can be connected to a structure of the adjustment assembly 13 other than the first adjustment member 131. No restrictions are placed here.

[0061] The setting of the adjustment space 13a can provide guidance and limit the range of motion of the first adjustment member 131, so that the first adjustment member 131 can move along the first direction through the adjustment space 13a, thereby driving the sound unit 10 to move in the concha cavity 2a along the first direction.

[0062] It is understood that the movement of the first adjusting member 131 along the first direction does not mean that the first adjusting member 131 can only move linearly along the first direction. The movement of the first adjusting member 131 along the first direction means that the first adjusting member 131 can make controlled and directional adjustments within a specific path. For example, the first adjusting member 131 can only move linearly along the first direction; or, the first adjusting member 131 can rotate or tilt to a certain extent while limiting the movement; or, the first adjusting member 131 does not move continuously, but achieves position changes by setting several fixed adjustment points.

[0063] It is understandable that the first adjusting member 131 can move relative to the connecting arm 12 under the action of an external force, which can be the force of hand operation.

[0064] The ear canal opening 2b, also known as the external auditory canal opening or ear hole, is the entrance part of the external auditory canal. It is 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 2 through the ear canal opening 2b. When the sound waves travel through the air to the ear canal opening 2b, they are guided into the external auditory canal and eventually transmitted to the eardrum, thus triggering the hearing process.

[0065] When the first adjusting member 131 moves along the first direction, it can drive the sound-generating unit 10 to move within the concha 2a along the first direction, thereby changing the relative position between the sound-generating unit 10 and the ear canal opening 2b. When the first adjusting member 131 moves the sound-generating unit 10 to increase the distance between the center of the sound-generating unit 10 and the center of the ear canal opening 2b, the sound-generating unit 10 is positioned away from the ear canal opening 2b, enabling open-ear sound generation. When the first adjusting member 131 moves the sound-generating unit 10 to decrease the distance between the center of the sound-generating unit 10 and the center of the ear canal opening 2b, the sound-generating unit 10 is positioned closer to the ear canal opening 2b, enabling semi-in-ear sound generation. In this way, the user can switch between different sound effects as needed.

[0066] Similarly, by adjusting the distance between the sound-generating unit 10 and the ear canal opening 2b, users can find the most suitable sound transmission path, reduce sound leakage, and create a better seal to enhance noise reduction. Furthermore, wearing comfort can also be adjusted.

[0067] The ear-clip earphone 1 provided in this application embodiment uses a first adjusting member 131 to move the sound-generating unit 10 relative to the connecting arm 12, thereby adjusting the relative position of the sound-generating unit 10 within the concha cavity 2a. This allows the sound-generating unit 10 to be positioned closer to or further away from the ear canal opening 2b, enabling switching between open-ear sound generation away from the ear canal opening 2b and semi-in-ear sound generation entering the ear canal opening 2b. Simultaneously, it reduces sound leakage and noise reduction capabilities, and adapts to different ear sizes 2, increasing wearing comfort. Users can adjust the wearing comfort and optimize the acoustic path according to their needs, making the ear-clip earphone 1 highly flexible in its adaptability. The adjustment space 13a increases the directional movement of the first adjusting member 131, providing a standardized adjustment mechanism that facilitates production and maintenance, while also reducing damage to the ear 2 during movement.

[0068] In some embodiments, the connecting arm 12 includes a first segment 121 and a second segment 122 connected to each other. The end of the first segment 121 away from the second segment 122 is connected to the adjustment assembly 13. The first segment 121 extends in a first direction. The second segment 122 bends and extends from the end of the first segment 121 away from the adjustment assembly 13 toward the direction close to the battery pack 11 and is connected to the battery pack 11.

[0069] In other words, after the connecting arm 12 is connected to the adjustment component 13, it can first extend a certain length along the first direction, and then extend by bending to connect with the battery pack 11.

[0070] In this embodiment, the arrangement of the first segment 121 and the second segment 122 of the connecting arm 12 increases the reliability of the connecting arm 12. The first segment 121 extends along the first direction, which is consistent with the extension direction of the adjustment space 13a, reducing the probability of the first segment 121 being bent and damaged, and also reducing damage to the ear. Of course, in the embodiment described below where the connecting arm 12 is partially inserted into the adjustment space 13a, the first segment 121 extending along the first direction also increases the smoothness of the movement of the adjustment space 13a and the first adjustment member 13a relative to the connecting arm 12, thereby increasing the adjustment reliability of the ear clip-on earphone 1.

[0071] In some embodiments, the first adjustment member 131 defines an adjustment space 13a.

[0072] In other words, the adjustment space 13a is defined by the structure of the first adjustment member 131 itself. When the first adjustment member 131 moves, there will be relative movement between the adjustment space 13a and the connecting arm 12. At this time, the adjustment component 13 can be connected to the connecting arm 12 through the first adjustment member 131, that is, through the adjustment space 13a. In this embodiment, the first adjustment member 131 can be directly connected to the connecting arm 12 and move relative to the connecting arm 12 through the adjustment space 13a. The adjustment component 13 does not need to be provided with an additional structure. The structure of the adjustment component 13 is simple, which makes the overall structure of the ear clip-on earphone 1 simpler as well.

[0073] It is understood that in this embodiment, the adjustment component 13 may only include the first adjustment member 131, and the entire adjustment component 13 may be formed as an integral structure.

[0074] In other embodiments, please refer to Figures 1 to 5 The first adjusting member 131 passes through the adjusting space 13a and moves in the first direction within the adjusting space 13a.

[0075] In other words, in this embodiment, the adjustment space 13a is defined by the structure of the adjustment component 13, excluding the first adjustment member 131. There is no direct connection between the first adjustment member 131 and the connecting arm 12. The first adjustment member 131 moves relative to the adjustment space 13a, and there is no relative movement between the adjustment space 13a and the connecting arm 12. In this embodiment, by moving the first adjustment member 131 along the adjustment space 13a, the structure of the first adjustment member 131 is simplified, the movement of the first adjustment member 131 is more stable, and the absence of a connection between the first adjustment member 131 and the connecting arm 12 facilitates maintenance and replacement of both.

[0076] It is understood that in this embodiment, the adjustment component 13 can be a split structure, and the first adjustment member 131 can be one of the split components.

[0077] In some embodiments, please refer to Figures 1 to 5 The adjustment assembly 13 also includes a second adjustment member 132. The adjustment space 13a extends through the second adjustment member 132 along the thickness direction. The first adjustment member 131 passes through the adjustment space 13a. The connecting arm 12 is connected to the end of the second adjustment member 132 away from the sound-generating unit 10 and is located outside the adjustment space 13a. There is no relative movement between the connecting arm 12 and the second adjustment member 132.

[0078] In this embodiment, the first adjusting member 131 does not participate in the formation of the adjusting space 13a, but is defined by the second adjusting member 132. The first adjusting member 131 and the second adjusting member 132 may be manufactured separately, and then the first adjusting member 131 and the second adjusting member 132 are connected through the adjusting space 13a.

[0079] The adjustment space 13a extends through the second adjustment member 132 along the thickness direction of the second adjustment member 132, and the first direction is perpendicular to the thickness direction of the second adjustment member 132.

[0080] The first adjusting member 131 is inserted into the adjusting space 13a, meaning that the first adjusting member 131 can move within the adjusting space 13a. The adjusting space 13a guides and positions the movement of the first adjusting member 131, confining the movement of the first adjusting member 131 within a preset space, and also provides support for the first adjusting member 131.

[0081] The connecting arm 12 is located outside the adjustment space 13a, which means it can avoid interfering with the first adjustment member 131 and does not affect the movement of the first adjustment member 131, thereby increasing the reliability of the arrangement of each component.

[0082] The connection method between the connecting arm 12 and the second adjusting member 132 is not limited; it can be snap-fit, adhesive, etc., and no restrictions are imposed here.

[0083] In this embodiment, the first adjusting member 131 moves within the adjustment space 13a defined by the second adjusting member 132. The second adjusting member 132 acts as a fixed platform, increasing the reliability of the movement of the first adjusting member 131. The connecting arm 12 and the second adjusting member 132 do not move relative to each other, and as a fixed connection, they increase the stability of the ear clip-on earphone 1. Of course, fine-tuning the second adjusting member 132 can also adjust the movement direction of the first adjusting member 131 and the sound-generating unit 10 within the ear clip cavity, better adapting to different ear shapes, increasing wearing comfort, and reducing pressure on the ear during adjustment.

[0084] In some embodiments, please refer to Figures 1 to 5 The first adjusting member 131 includes a slider, and the adjusting space 13a is formed as a slide rail, with the slider slidingly engaging with the slide rail.

[0085] In this embodiment, the movement of the first adjusting member 131 along the first direction is sliding, and the slider generates a linear displacement along the first direction along the slide rail.

[0086] In this embodiment, the first adjustment member 131 can slide along a preset trajectory through the cooperation of the slider and the slide rail. The movement path of the first adjustment member 131 is precise and controlled, reducing unnecessary offset and shaking, increasing the adjustment reliability of the ear clip-on headphones 1. Users can easily adjust the position of the sound unit 10 by simply sliding to find the most suitable sound transmission path and wearing position.

[0087] In some embodiments, please refer to Figures 1 to 5 The slide rail is formed as a continuous closed structure to stop and limit the movement of the slider within the slide rail.

[0088] Here, "the slide rail is formed as a continuous closed structure" means that the slide rail is a continuous and closed ring or similar structure that completely surrounds the movement path of the slider.

[0089] In this way, the slide rail naturally provides a physical stop and limit for the slider, so that the slider can slide within a predetermined range without coming off the slide rail, increasing the reliability of adjustment and improving the safety and stability of wearing.

[0090] For example, the slide rail can be roughly circular.

[0091] The connection method between the first adjusting member 131 and the sound generating unit 10 is not limited; it can be snap-fit, glued, etc.

[0092] In some embodiments, please refer to Figure 2 One of the first adjusting member 131 and the sound generating unit 10 has a locking block 101, and the other has a locking slot, with the locking block 101 inserted into the locking slot.

[0093] In this embodiment, the first adjusting member 131 and the sound generating unit 10 are connected by the cooperation of the card block 101 and the card slot. The connection method is simple, and when it is necessary to disconnect the connection between the first adjusting member 131 and the sound generating unit 10, the card block 101 and the card slot can be easily disconnected, so as to repair or replace the first adjusting member 131 and the sound generating unit 10.

[0094] For example, a card block 101 is formed in the sound-generating unit 10, and a card slot is formed in the first adjusting member 131.

[0095] In some embodiments, the first adjusting member 131 and the second adjusting member 132 are separate structures.

[0096] In other words, the first adjusting component 131 and the second adjusting component 132 are manufactured separately and then assembled to form the adjusting assembly 13. This makes it easier to adjust the first adjusting component 131 and the second adjusting component 132 independently, increases assembly reliability, and facilitates maintenance and replacement.

[0097] For example, during assembly, the first adjustment component 131 and the sound unit 10 are first assembled into a pre-assembled whole, the second adjustment component 132, the connecting arm 12 and the battery pack 11 are assembled into a pre-assembled whole, and then the first adjustment component 131 is installed in the adjustment space 13a, thereby realizing the overall assembly of the ear clip-on headphones 1.

[0098] In some embodiments, the first adjusting member 131 and the second adjusting member 132 are rigid structures.

[0099] Here, rigid structure refers to a structure that has a certain strength, rigidity and is not easily deformed.

[0100] The first adjusting member 131 and the second adjusting member 132 are formed as rigid structures, which can have good strength and rigidity to maintain stability under long-term use and frequent adjustment, and reduce the risk of deformation caused by external impact or improper operation.

[0101] For example, the first adjusting member 131 and the second adjusting member 132 may be made of metal (such as aluminum alloy or stainless steel) or high-strength engineering plastic.

[0102] In some embodiments, the connecting arm 12 is a rigid structure. Thus, the connecting arm 12 possesses a certain strength and rigidity, making it less prone to deformation. This increases the overall structural strength and stability of the earcup earphone 1. In dynamic usage environments, the rigid connecting arm 12 can reduce the likelihood of the earcup earphone 1 falling off or deforming.

[0103] In other embodiments, the connecting arm 12 is a flexible structure. That is, the connecting arm 12 has a certain degree of deformability and can bend within a certain range. Exemplarily, the connecting arm 12 can be made of flexible materials, such as silicone, rubber, etc.

[0104] In this embodiment, the soft-structured connecting arm 12 has good flexibility, making it easy to fit naturally to the user's ear 2, reducing pressure on the ear 2 and improving wearing comfort.

[0105] In some embodiments, the connecting arm 12 has a wire passage, and the ear clip-on earphone 1 includes a connecting wire, one end of which is connected to the battery pack 11, and the other end of which passes through the wire passage out of the connecting arm 12 and is electrically connected to the sound unit 10.

[0106] In other words, when connecting the battery pack 11 and the adjustment assembly 13, the connecting arm 12 also provides a wire passage, allowing the connecting wire to extend from the battery pack 11 to the sound unit 10 through the wire passage. The connecting wire extending out of the connecting arm 12 means that a portion of the connecting wire is located outside the connecting arm 12, i.e., exposed on the outer surface of the ear clip-on earphone 1. This facilitates electrical connection with the sound unit 10, allowing the electrical energy from the battery pack 11 to be transferred to the sound unit 10 through the connecting wire. In this embodiment, the wire passage within the connecting arm 12 reduces the exposed portion of the connecting wire, reduces cable tangling, and increases the structural reliability and aesthetic appeal of the ear clip-on earphone 1.

[0107] In some embodiments, please refer to Figures 6 to 8 At least a portion of the first adjusting member 131 is hollow to define an adjusting space 13a. A portion of the connecting arm 12 passes through the adjusting space 13a. The adjusting space 13a is movable relative to the connecting arm 12 to increase or decrease the size of the portion of the connecting arm 12 located outside the adjusting space 13a.

[0108] In this embodiment, the adjustment space 13a is defined by the first adjustment member 131, that is, there will be relative movement between the adjustment space 13a and the connecting arm 12.

[0109] In this embodiment, by adjusting the movement of the space 13a relative to the connecting arm 12, the exposed length of the connecting arm 12 is changed, thereby adjusting the relative position of the sound-generating unit 10 within the concha cavity 2a, thus reducing sound leakage and improving sound quality and sound insulation. The relative movement between the first adjusting member 131 and the connecting arm 12 occurs within the first adjusting member 131, which can increase the aesthetic appearance of the ear clip-on earphone 1. At the same time, in this embodiment, there is no need to set a second adjusting member 132, and the structure of the ear clip-on earphone 1 can be simpler.

[0110] The connection method between the first adjusting member 131 and the connecting arm 12 is not limited.

[0111] In some embodiments, one of the first adjusting member 131 and the connecting arm 12 has a locking structure, and the other has a locking position for locking engagement with the locking structure. The locking structure can exit the current locking position and insert into another locking position during the movement of the first adjusting member 131 relative to the connecting arm 12.

[0112] In this embodiment, through the cooperation of the locking structure and the locking position, when no adjustment is needed, the locking position and the locking structure lock together, so that the connecting arm 12 and the first adjusting member 131 can be stably in the current position, increasing the overall stability of the ear clip-on headphones 1. When adjustment is needed, an external force is applied to the first adjusting member 131, so that the connecting arm 12 and the adjustment space 13a move relative to each other, thereby the locking structure and the locking position move relative to each other, and the locking structure exits the current locking position. When adjusted to a suitable position, another locking position is inserted to achieve reliable adjustment.

[0113] The locking structure can be located on the first adjusting member 131, and the locking position can be located on the connecting arm 12; or, the locking structure can be located on the connecting arm 12, and the locking position can be located on the first adjusting member 131.

[0114] For example, in some embodiments, the locking position includes a recess in the connecting arm 12, and the locking structure includes a ball protruding from the inner surface of the adjustment space 13a, the ball being inserted into the recess.

[0115] In other words, locking and unlocking are achieved through the cooperation of the ball and the groove, which increases the reliability of docking. The structure of the ball and the groove is simple, which makes it easier to reduce the manufacturing difficulty of the connecting arm 12 and the first adjusting member 131.

[0116] In some embodiments, the connecting arm 12 is a soft structure and the first adjusting member 131 is a rigid structure.

[0117] In this embodiment, the first adjusting member 131 is a rigid structure. When it is subjected to external force to drive the sound generating unit 10 to move, the first adjusting member 131 has sufficient strength and rigidity to resist deformation and increase the reliability of movement. The connecting arm 12 is a soft structure that can undergo appropriate deformation, thereby facilitating docking with the first adjusting member 131. Furthermore, when moving relative to the first adjusting member 131 during sound generation, it adapts to the movement and reduces friction and wear.

[0118] In some embodiments, the connecting arm 12 has a wire passage, and the ear clip-on earphone 1 includes a connecting wire, one end of which is connected to the battery pack 11, and the other end passes through the wire passage and the adjustment space 13a and is electrically connected to the sound unit 10.

[0119] In other words, in this embodiment, the connecting wire can enter the adjustment space 13a through the wire passage in the connecting arm 12 and thus be electrically connected to the sound unit 10. In this way, a small part or almost no part of the connecting wire is exposed on the outer surface of the ear clip-on earphone 1, which increases the reliability of the wiring and the aesthetics of the appearance.

[0120] In some embodiments, please refer to Figure 1The first adjusting member 131 can drive the sound-generating unit 10 to produce a linear displacement along the first direction, and the linear displacement d is 10mm to 22mm. That is, 10mm≤d≤22mm, for example, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, etc.

[0121] In this embodiment, the linear displacement setting provides a sufficient adjustment range, enabling users to switch between open and semi-in-ear sound, reducing sound leakage and enhancing noise reduction capabilities. It also adapts to the shape of the user's ear 2, ensuring that the movement of the first adjustment member 131 will not damage the user's ear 2, reducing ear 2 pressure, and increasing adjustment reliability.

[0122] In some embodiments, please refer to Figure 4 The angle α between the first direction and the reference line is 30° to 60°, where the reference line is a straight line passing through the center of the sound-generating unit 10 and parallel to the direction of gravity. That is, 30°≤α≤60°, for example, 30°, 32°, 36°, 39°, 40°, 43°, 45°, 47°, 50°, 54°, 58°, 60°, etc.

[0123] In this embodiment, the angle between the first direction and the reference line allows the first adjustment member 131 and the sound-generating unit 10 to move in a more suitable direction within the ear clip cavity, so that there is sufficient displacement adjustment within the concha cavity 2a to the distance from the ear canal opening 2b, without harming the ear 2, thereby increasing the reliability of movement and the adjustment reliability of the ear clip-on earphone 1.

[0124] In some embodiments, please refer to Figure 1 The shortest straight-line distance D between the sound-generating unit 10 and the battery pack 11 is 3mm to 15mm. That is, 3mm≤D≤15mm, for example, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0125] In this embodiment, when the first adjusting member 131 drives the sound-generating unit 10 to move, the relative position between the sound-generating unit 10 and the battery pack 11 also changes. Within the range of movement of the first adjusting member 131 and the sound-generating unit 10, the distance between the sound-generating unit 10 and the battery pack 11 can apply a suitable clamping force to the auricle. It will not be too loose, causing the ear clip-on headphones 1 to come off, nor too tight, increasing the pressure on the ear 2. This increases the adjustability of the ear clip-on headphones 1 while improving wearing comfort.

[0126] Understandably, the clip-on earphone 1 can be set to an initial position, which allows the user to easily identify the initial position of the adjustment component 13. In this position, when adjustment is needed, external force can be applied to the adjustment component 13. The initial position can be the position where the adjustment component 13 is not subjected to external force and the distance between the center of the sound unit 10 and the center of the ear canal opening 2b is at its maximum. During adjustment, the distance between the center of the sound unit 10 and the center of the ear canal opening 2b can be gradually reduced to gradually achieve the switching from open-ear sound emission away from the ear canal opening 2b to semi-in-ear sound emission into the ear canal opening 2b.
