[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] In related technologies, conventional ear clip-on headphones are placed in the middle of the ear and are fixed by clamping the middle of the auricle. In related technologies, the ear hook design of open earlobe headphones is generally fixed. For example, when targeting large ears or small ears, the sound output part may be deviated from the ear canal, affecting the sound quality. Moreover, due to the offset wearing position, it affects the wearing comfort.

[0035] To address the aforementioned technical problems, this application proposes an earphone; please refer to [link / reference needed]. Figure 1 It includes a sound-generating part 100, a battery compartment 200, and a connecting bridge 300.

[0036] The sound-generating part 100 is worn in the concha of the user's ear. The sound-generating part 100 is the main audio output part of the headphones. It includes an audio driver unit (such as a speaker) for converting electrical signals into sound signals.

[0037] The battery compartment 200 is the power supply part of the headphones. It contains electrical components (such as power supply and circuit board) and related circuit elements to provide power to the headphone's sound-generating part 100 and other functional components. The battery compartment 200 includes a second shell and is worn behind the user's ear. It works in conjunction with the sound-generating part 100 to ensure the stability of the headphones when worn.

[0038] The connecting bridge 300 connects the sound-generating part 100 and the battery compartment 200, ensuring a stable connection and mechanical strength between the two. The connecting bridge 300 may include conductive wires and memory metal wires. The conductive wires enable electrical connection between the electrical components of the sound-generating part 100 and the electrical components of the battery compartment 200. The memory metal wires connect the sound-generating part 100 and the battery compartment 200. Due to the super-elastic properties of the memory metal wires, the sound-generating part 100 and the battery compartment 200 tend to move closer to each other, thereby enabling the headphones to be stably worn on the user's ears.

[0039] The shape memory wire can be titanium shape memory wire, nickel-titanium alloy wire, copper-based shape memory wire (such as copper-zinc alloy, copper-aluminum alloy, etc.) and iron-based shape memory wire (such as iron-manganese alloy, iron-platinum alloy, etc.), etc. This application does not limit the type of shape memory wire.

[0040] Furthermore, the connecting bridge 300 includes a first end 310 movably connected to the battery compartment 200. The first end 310 is movable relative to the battery compartment 200 to change the distance between the sound-emitting part 100 and the battery compartment 200. In this way, when targeting large ears or small ears, the sound-emitting part 100 can still be worn in the user's concha, and the battery compartment 200 can still be worn behind the user's ear. The connecting bridge 300 can maintain a sufficient gap with the ear, resulting in less or no ear-pinch pain during long-term wear.

[0041] It should be understood that the headphones targeted in this application are open-back headphones, specifically earlobe open-back headphones or ear-hook open-back headphones.

[0042] When the earlobe-style open-back headphones are used, the opening of the connecting bridge 300 faces the top of the wearer's head. At this time, the distance between the sound-emitting part 100 and the battery compartment 200 is adjusted by the movement of the first end 310 relative to the battery compartment 200. This allows the connecting bridge 300 to maintain a sufficient gap with the wearer's earlobe, resulting in less or no ear-top pain during long-term wear.

[0043] When the ear-hook type open-back headphones are used, the opening of the connecting bridge 300 faces the lower jaw of the wearer. At this time, the distance between the sound-emitting part 100 and the battery compartment 200 is adjusted by the movement of the first end 310 relative to the battery compartment 200. This allows the connecting bridge 300 to maintain a sufficient gap with the wearer's auricle, resulting in less or no ear-pinch pain after prolonged wear.

[0044] Specifically, a clamping cavity is formed between the sound-emitting part 100, the battery compartment 200, and the connecting bridge 300. Therefore, by moving the first end 310 relative to the battery compartment 200, the size of the clamping cavity can be adjusted to accommodate people with different ear sizes within a certain range, ensuring wearing comfort and sound quality.

[0045] Please see Figure 2 When the earphone is in the wearing state, the sound-emitting part 100 has a first projection on the first plane, the battery compartment 200 has a second projection on the first plane, the connecting bridge 300 has a third projection on the first plane, and the outline of the clamping cavity has a fourth projection on the first plane. The first projection and the second projection are both tangent to the first straight line. (In this embodiment, the side of the first projection and the second projection away from the third projection is a curved surface, so the first straight line is the common tangent of the first projection and the second projection). The first straight line and the fourth projection enclose the clamping space, and the area of ​​the clamping space is S.

[0046] The first straight line is located on the side where both the first and second projections are far from the third projection, and its first end is movable relative to the battery compartment 200, so that S varies within a range of 50mm. 2 -250mm 2 That is, by connecting the bridge 300 relative to the battery compartment 200, S can be made to move within 50mm. 2 100mm 2 150mm 2 200mm 2 250mm 2 You can switch between any two of the above values, which will change the size of the clamping cavity accordingly, thus adapting to people with different ear sizes within a certain range, ensuring wearing comfort and sound quality.

[0047] It should be noted that the first plane can be defined as follows: when the headphones are placed on a horizontal plane, the horizontal plane is the first plane. The horizontal plane has a vertically set X-axis and Y-axis, and the projection direction is the Z-axis direction.

[0048] Alternatively, the first plane can be a plane perpendicular to the thickness direction of the sound-emitting part 100, where the thickness direction refers to the direction in which the sound-emitting part approaches or moves away from the ear when the headphones are worn.

[0049] Since the first end 310 is movable relative to the battery compartment 200, the sound-emitting part 100 can be stably worn in the user's concha, ensuring that the sound can be directly transmitted to the user's ear canal, providing clear sound quality and a comfortable wearing experience.

[0050] Please see Figure 3 In one embodiment, the earphone further includes an adjustment assembly 400, which includes an adjustment part 410 and a locking part 420. The adjustment part 410 is connected to one of the battery compartment 200 and the first end 310, and the locking part 420 is connected to the other of the battery compartment 200 and the first end 310. The locking part 420 is used to lock and unlock with the adjustment part 410 to realize the locking and unlocking of the first end 310 and the battery compartment 200.

[0051] Optionally, the adjusting part 410 can be connected to the first end 310, in which case the locking part 420 is used to connect to the battery compartment 200, or the adjusting part 410 can be connected to the battery compartment 200, in which case the locking part 420 is used to connect to the first end 310. This application does not limit the embodiments. This application uses the example of the adjusting part 410 being connected to the first end 310 and the locking part 420 being used to connect to the battery compartment 200 for illustrative purposes.

[0052] The locking part 420 and the adjusting part 410 lock together to lock the distance between the sound-emitting part 100 and the battery compartment 200, thereby ensuring that the distance between the sound-emitting part 100 and the battery compartment 200 is appropriate and meets the wearer's requirements. The tight fit between the locking part 420 and the adjusting part 410 ensures the stability of the headphones during wear, and can effectively prevent the headphones from slipping or loosening even during strenuous exercise or outdoor activities. In addition, the correct wearing position can reduce sound leakage and distortion, thereby optimizing sound quality.

[0053] Understandably, the position of the locking part 420 can be set by selecting an appropriate distance between the sound-emitting part 100 and the battery compartment 200.

[0054] By unlocking the locking part 420 and the adjusting part 410, the adjusting part 410 can move relative to the battery compartment 200, that is, the first end 310 of the connecting bridge 300 moves relative to the battery compartment 200, which means that the appropriate distance between the sound-emitting part 100 and the battery compartment 200 changes, thereby meeting the wearing needs of users with large ears and small ears.

[0055] Furthermore, multiple locking parts 420 are provided, and the multiple locking parts 420 are arranged at intervals along the movement direction of the first end 310. Since the locking parts 420 can lock and unlock with the adjustment part 410, the distance between the sound-emitting part 100 and the battery compartment 200 is different when different locking parts 420 are connected to the adjustment part 410. In this way, the connection between the corresponding locking part 420 and the adjustment part 410 can be adjusted according to the size of the wearer's ears, thereby ensuring the stability of the headphones when worn.

[0056] The number of locking parts 420 can be 2, 3, 4, or 5, etc., and is not limited in this embodiment. It can be set according to the actual situation.

[0057] It should be noted that in medicine, anatomy, and other fields, the human body can be defined by three basic planes: the sagittal plane, the coronal plane, and the horizontal plane; and three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a section perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts. The coronal plane is a section perpendicular to the ground along the left-right direction of the body, dividing the body into anterior and posterior parts. The horizontal plane is a section parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the left-right direction of the body and perpendicular to the sagittal plane; and the vertical axis is the axis along the vertical direction of the body and perpendicular to the horizontal plane. Furthermore, the "front side of the ear" in this application is a concept relative to "back side of the ear." The former refers to the side of the ear that is away from the head, while the latter refers to the side of the ear that faces the head. Both of them refer to the user's ear.

[0058] Please see Figures 4-5 The diagram shows the structure of the headphones when they are in use, viewed along the coronal axis, with the adjustment part 410 locked to different locking parts 420. The distance between the sound-emitting part 100 and the battery compartment 200 is different when the adjustment part 410 is locked to different locking parts 420, thus ensuring the stability of the headphones when worn.

[0059] Please see Figure 4In some embodiments, the plurality of locking portions 420 include a first locking portion 420 and a second locking portion 420 arranged adjacent to each other. The connecting bridge 300 also includes a second end portion 320 connected to the sound-emitting portion 100. When the adjusting portion 410 is locked with the first locking portion 420, the angle between the axis of the second end portion 320 and the axis of the sound-emitting portion 100 is α. When the adjusting portion 410 is locked with the second locking portion 420, the angle between the axis of the second end portion 320 and the axis of the sound-emitting portion 100 is β. The difference between α and β is in the range of 7° to 8°.

[0060] The difference between a and b can be any two numbers between 7°, 7.2°, 7.5°, 7.8°, 8° or above. This application embodiment does not limit the value. By using the difference between a and b in the range of 7° to 8°, the angle formed by the connecting bridge 300 and the battery compartment 200 can be adjusted, thereby meeting the needs of different ear sizes within a certain range and having a wide range of applicability.

[0061] Please continue reading. Figure 6 In some embodiments, the battery compartment 200 includes an outer shell 210, the outer shell 210 having a receiving cavity 210a, a locking part 420 located within the receiving cavity 210a, and an opening 210b on the outer surface of the outer shell 210 for the adjustment part 410 to extend into the receiving cavity 210a.

[0062] The outer shell 210 serves as the exterior component of the battery compartment 200. The cavity 210a formed by it can prevent electrical components and related circuit components from entering. In this embodiment, by placing the locking part 420 inside the cavity 210a, the space inside the battery compartment 200 is utilized, making the entire headphone layout more compact and enabling the entire headphone to be designed to be lightweight and miniaturized.

[0063] Furthermore, since the adjustment part 410 also extends into the receiving cavity 210a, that is, the connection between the adjustment part 410 and the locking part 420 is located inside the receiving cavity 210a, the outer shell 210 can protect the adjustment part 410 and the locking part 420, reducing the impact of external water droplets and dust on the adjustment part 410 and the locking part 420.

[0064] Furthermore, please refer to Figure 6 The battery compartment 200 also includes a partition 220, which is disposed in the receiving cavity 210a and divides the receiving cavity 210a into a first cavity 211a and a second cavity 212a. The first cavity 211a is used to place electrical components, the locking part 420 is located in the second cavity 212a, and the opening 210b communicates with the second cavity 212a.

[0065] The use of partition 220 allows for more efficient planning and utilization of the accommodating cavity 210a. The first cavity 211a focuses on the safe storage of electrical components, while the second cavity 212a is used to house the adjustment part 410 and the locking part 420. This layout satisfies functional requirements while ensuring the compactness and neatness of the structure.

[0066] With the partition 220 in place, even if dust and water droplets enter the second cavity 212a through the opening 210b, they will have difficulty contacting the electrical components and related circuit components in the first cavity 211a, thus ensuring the safety and stability of the headphones.

[0067] The partition 220 can be integrally injection molded with the outer shell 210. For example, the partition 220 and the outer shell 210 can both be made of plastic or composite materials such as glass fiber. This application embodiment does not impose any restrictions.

[0068] In this application, the connection between the locking part 420 and the adjusting part 410 can be magnetic, snap-fit, or threaded, etc., to improve the convenience and reliability of locking. In this embodiment, the locking part 420 and the adjusting part 410 are connected by a snap-fit ​​connection for illustrative purposes.

[0069] Please return to the reference. Figure 2 The locking part 420 includes a groove 420a disposed on the partition member 220. The adjusting part 410 includes a baffle 411 and an elastic protrusion 412. The baffle 411 is connected to the first end 310. The elastic protrusion 412 is located on the side of the baffle 411 facing the partition member 220 and is connected to the baffle 411. The groove 420a can accommodate at least a portion of the elastic protrusion 412. When the elastic protrusion 412 is engaged with the groove 420a, the elastic protrusion 412 is locked with the groove 420a. When the elastic protrusion 412 is separated from the groove 420a, the elastic protrusion 412 is unlocked from the groove 420a.

[0070] The elastic protrusion 412 engages with the groove 420a to complete the locking, and the elastic protrusion 412 separates from the groove 420a to complete the unlocking. This means that the elastic protrusion 412 and the groove 420a can be quickly locked and unlocked without any other structural components, which greatly improves the convenience of headphone adjustment.

[0071] In some implementations, the opening size of the groove 420a is smaller than the size of the elastic protrusion 412. The locking mechanism between the elastic protrusion 412 and the groove 420a ensures the stability of the connecting bridge 300 at this position. When the elastic protrusion 412 is engaged with the groove 420a, due to the restoring force of the elastic material, the protrusion will fit tightly within the groove 420a, effectively preventing the connecting bridge 300 from accidentally moving or loosening due to external factors (such as vibration, collision, etc.), thereby ensuring the stability and safety of the overall structure.

[0072] The elastic bump 412 can be made of rubber, polyurethane foam, or metal such as copper, and there are no restrictions in this embodiment.

[0073] Furthermore, the partition 220 has a first curved surface 221 and a plurality of second curved surfaces 222 on the side facing the second cavity 212a. The first curved surface 221 protrudes towards the second cavity 212a, and the plurality of second curved surfaces 222 are recessed away from the second cavity 212a. The plurality of second curved surfaces 222 are correspondingly formed with a plurality of locking portions 420.

[0074] The surface of the elastic protrusion 412 can be spherical, and the groove 420a is also an arc-shaped groove. The wall of the arc-shaped groove is a second curved surface 222. When the elastic protrusion 412 is inserted into the groove 420a, due to the restoring force of the elastic material, the protrusion will fit tightly in the groove 420a. The setting of the second curved surface 222 can increase the contact area between the elastic protrusion 412 and the groove 420a, thereby ensuring stability. On the other hand, when the elastic protrusion 412 is inserted into the groove 420a, under the action of the elastic restoring force, the elastic protrusion 412 abuts against the inner wall of the groove 420a, that is, the elastic protrusion 412 is also difficult to rotate in the groove 420a.

[0075] Optionally, the first curved surface 221 allows the elastic protrusion 412 to move smoothly from one groove 420a to another groove 420a, thereby enabling the adjustment part 410 to quickly lock with another locking part 420.

[0076] Based on the previous embodiment, please refer back to the previous document. Figure 3 and combined Figure 6 The baffle 411 has a first side 411a and a second side 411b facing each other. The first side 411a faces the partition 220, and the elastic protrusion 412 is located on the first side 411a. The first side 411a is in contact with the first curved surface 221, and the second side 411b is connected to the first end 310.

[0077] By attaching the first side surface 411a of the baffle 411 to the first curved surface 221 of the partition 220, the natural shape of the curved surface can be used to make close contact with the side surface of the baffle 411, which can effectively increase the contact area between the two and thus improve the stability of the entire structure. This not only enhances the connection strength between the baffle 411 and the partition 220, but also reduces the risk of shaking or displacement caused by external forces.

[0078] It should be understood that the connection between the first end 310 and the second side 411b is a columnar structure, which can form a guide. The opening 210b on the surface of the outer shell 210 can form a guide hole. When the guide slides along the guide rod, the elastic protrusion 412 can be engaged in different grooves 420a. That is, the adjustment part 410 can be locked and unlocked with different locking parts 420 according to the set trajectory. This makes it convenient to adjust the distance between the headphone sound-emitting part 100 and the battery compartment 200 according to different ear sizes, ensuring comfort and stability when wearing, as well as sound quality.

[0079] Furthermore, the second side 411b is attached to the inner wall of the battery compartment 200 and the opening 210b is sealed. In this way, water droplets and dust and other impurities are difficult to enter the second cavity 212a through the opening 210b, which protects the connection between the locking part 420 and the adjusting part 410 and improves the smoothness of the adjusting part 410 during movement.

[0080] It should be noted that in this embodiment, the adjustment part 410 moves within a plane. When the headphones are worn, this plane can be parallel to the sagittal plane of the human body, or it can be at a certain angle to the sagittal plane of the human body, such as 5°, 7°, 10°, etc. There are no restrictions here. What is clear is that the multiple locking parts 420 are spaced apart on this plane. In one embodiment of this application, the multiple locking parts 420, that is, the multiple grooves 420a, are spaced apart on the outer contour surface of the partition 220.

[0081] It is also important to understand that since the adjustment part 410 is movable, the conductive wire of the connecting bridge 300 can extend through the first end 310 and the baffle 411, and can extend through the side of the baffle 411.
