Description

Technical Field

[0001] The present application relates to the technical field of earphones, and in particular to an ear-clip earphone. Background Art

[0002] With the booming development of the smart wearables industry, earphones are becoming increasingly diverse, and users are increasingly demanding differentiated products. As earphones evolve, the duration of a single charge is increasing, and users are increasingly demanding products that are more convenient and comfortable to wear for extended periods of time. Clip-on earphones, which clip onto the ear, allow for extended wear without intruding, ensuring environmental awareness while reducing bacterial growth in the ear canal.

[0003] The ear shell structure and ear clip structure are key components in the design of ear clip headphones, enabling the headphones to be fixed around the user's ears. In related art, ear clip structures are all fixed and made of hard materials, meaning their shape is not adjustable. Due to differences in the size and shape of the auricles of different users, this fixed ear clip structure has difficulty adapting to the natural curve and shape of the auricle and cannot be adjusted according to the specific shape and size of the ear. As a result, the clamping force generated by the ear clip headphones cannot be well adapted to the wearing needs of different users. This may cause the ear clip headphones to be uncomfortable to wear or easily become loose during wearing. Utility Model Content

[0004] An embodiment of the present application provides an ear-clip earphone that can provide a better wearing experience by adjusting the connecting bridge.

[0005] An embodiment of the present application provides an ear-clip earphone, comprising a sound-emitting part, a fixed part and a connecting bridge, wherein the connecting bridge comprises an outer cover and a memory metal part, wherein the two ends of the outer cover are respectively connected to the sound-emitting part and the fixed part, and the memory metal part is arranged inside the outer cover and extends along the length direction of the outer cover; the memory metal part comprises a plastically deformable part and an elastic part connected to each other, and the plastically deformable part can bend and deform under the action of an external force to adjust the distance between the sound-emitting part and the fixed part.

[0006] The ear clip type earphone based on the embodiment of the application is provided with a sound generating part and a fixing part connected by an outer cover, and a memory metal part is arranged in the outer cover. The memory metal part comprises a plastic deformation part and an elastic part connected with each other. The elastic part provides necessary elasticity, so that the memory metal part can be finely adjusted according to the auricle shape of the user, and better adapt to the natural curve and shape of the auricle, and improve the wearing comfort. The plastic deformation part can be bent and deformed under external force. The plastic bending deformation of the plastic deformation part can adjust the distance between the sound generating part and the fixing part, so that the ear clip type earphone is more closely attached to the ear, and the risk of loosening or falling off of the earphone during wearing is reduced. The user can bend and deform the plastic deformation part of the memory metal part through external force according to the own needs, so as to quickly and simply adjust the size of the earphone. In this way, the distance between the sound generating part and the fixing part can be more suitable for the auricle shape and size of the user, so that the clamping force generated by the ear clip type earphone during wearing is more appropriate, and the comfort during wearing is better.

[0018] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0019] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0020] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0022] Earphones (Earphones, Headphones, Head-sets, Earpieces) are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears.

[0023] Wireless headphones are still relatively new in the audio industry. They utilize Bluetooth technology to connect to a phone or other device without wires, allowing users to wirelessly stream audio. Their key advantages include being free of wires, ease of portability, and ease of use, making them particularly suitable for exercise.

[0024] In recent years, ear clip headphones have gained increasing attention as a new wireless headphone design. These ear clips typically utilize air conduction, which eliminates ear canal obstruction and provides increased comfort. They also maintain a clear sound barrier, allowing users to communicate with the outside world when needed.

[0025] In the related art, ear-clip headphones include an ear shell structure and an ear clip structure, which is used to secure the headphones around the user's ears. The ear clip structures in the related art are all fixed and made of hard materials, meaning their shape is not adjustable. Due to differences in the size and shape of people's auricles, this fixed ear clip structure has difficulty adapting to the natural curve and shape of the auricle and cannot be adjusted according to the specific shape of the ear. This may cause the ear-clip headphones to not fit properly on some people's ears, easily slipping off during wear, lacking flexibility, and resulting in discomfort or loosening when worn.

[0026] To resolve the above issues, please refer to Figure 1 The present application proposes an ear-clip earphone 100, comprising a sound-emitting portion 10, a fixing portion 30 and a connecting bridge 20. The sound-emitting portion 10 is provided with a speaker unit (not shown), which is a transducer device for converting electrical signals into sound signals. The sound-emitting portion 10 is worn at the opening of the ear canal. The fixing portion 30 contains a battery (not shown) for providing power to the speaker unit to ensure its continuous operation. The battery has an independent storage space, which allows the battery to be designed to be larger, so that the ear-clip earphone 100 has a corresponding longer battery life. The connecting bridge 20 serves as a connecting structure, with its two ends respectively connecting the sound-emitting portion 10 and the fixing portion 30. The connecting bridge 20 can be an open arc structure to adapt to the shape of different users' ears.

[0027] The specific form of the battery is not limited. For example, a rechargeable lithium battery can be used, which makes the ear clip-on earphone 100 easy to use and carry.

[0028] Of course, the number of batteries can be one or two, and the ear clip-on headphone 100 also includes a control circuit board. If there is only one battery, the control circuit board and battery can be located together in the fixed portion 30. Of course, the control circuit board and speaker unit can also be located in the sound-emitting portion 10, while the battery is located separately in the fixed portion 30. If there are two batteries, the volume of each battery can be reduced accordingly, provided the capacity is the same. In this case, the two batteries can be placed in the sound-emitting portion 10 and the fixed portion 30, respectively. This application does not limit these arrangements.

[0029] The sound-emitting portion 10 and the fixing portion 30 can be made of plastic, metal, silicone, etc. The sound-emitting portion 10 containing the speaker unit can be constructed into a relatively smooth spherical structure so that the ear clip-on earphone 100 can fit more closely to the ear canal opening after being worn, providing a tighter abutment effect, which helps to improve the comfort when worn and the directionality of the sound. A sound-emitting opening is provided on the sound-emitting portion 10 for transmitting the sound generated by the speaker unit to the ear canal opening of the user. The fixing portion 30 containing the battery can be constructed into a relatively flat pancake-shaped structure with an abutting surface. The abutting surface can abut against the back of the user's ear when worn, forming a certain supporting force, thereby increasing the wearing stability of the ear clip-on earphone 100, and cooperating with the sound-emitting portion 10 containing the speaker unit to form a certain clamping force to ensure that the ear clip-on earphone 100 is fixed to the ear.

[0030] like Figure 2 and Figure 3 As shown, the connecting bridge 20 includes an outer cover 21 and a memory metal part 22. The two ends of the outer cover 21 are respectively connected to the sound-emitting part 10 and the fixed part 30. The material of the outer cover 21 can be one of thermoplastic polyurethane elastomer (TPEE), thermoplastic elastomer (TPU), and silicone resin. The above materials have a certain degree of softness, which helps to improve wearing comfort and alleviate the problem of ear pain caused by squeezing the human ear due to wearing for too long. The user can freely bend the outer cover 21 to achieve easy wearing and removal, improving the convenience of use. A snap-in groove 10a is provided on both the sound-emitting part 10 and the fixed part 30. A snap-in seat 211 is formed at both ends of the outer cover 21. The two snap-in seats 211 are respectively embedded in the snap-in groove 10a to form a stable connection between the outer cover 21 and the sound-emitting part 10 and the fixed part 30.

[0031] The memory metal piece 22 is disposed within the outer cover 21. Specifically, the memory metal piece 22 may be housed within the outer cover 21 and extend along its length. The memory metal piece 22 exhibits excellent durability and fatigue resistance, capable of withstanding multiple deformations without sacrificing its recovery properties. Therefore, the user can adjust the degree of bending of the memory metal piece 22 to suit the shape and size of their auricle, thereby varying the spacing between the sound-emitting portion 10 and the fixing portion 30. This allows for fine-tuning based on the user's auricle shape, increasing the wearing flexibility of the ear clip earphone 100.

[0032] In some embodiments, the memory metal piece 22 is embedded within the outer cover 21, reducing external space usage and maintaining a clean and aesthetically pleasing appearance. It also protects the memory metal piece 22 from corrosion caused by sweat, slowing down aging and maintaining its performance. The two ends of the memory metal piece 22 extend toward the sound-emitting portion 10 and the fixing portion 30, respectively. The memory metal piece 22 is flat, conforming to the shape of the human thumb and index finger, making it easier for the user to pinch the outer cover 21 to adjust the opening size of the ear clip-on earphone 100. Compared to a round memory metal piece 22, the flat memory metal piece 22 improves the distortion correction force. Furthermore, the thickness direction of the outer cover 21 is consistent with the thickness direction of the memory metal piece 22, i.e., the outer cover 21 and the memory metal piece 22 are arranged in the same direction, making it easier for the user to pinch the outer cover 21 and the memory metal piece 22 inside it with their fingers to bend and adjust it to better fit their ears. The memory metal member 22 can be made of titanium alloy, nickel-titanium alloy, or the like. In combination with the aforementioned flat structure, the memory metal member can specifically be a titanium alloy sheet, a nickel-titanium alloy sheet, or the like. The low density of titanium alloy and nickel-titanium alloy sheets makes the ear-clip earphone 100 more lightweight and less burdensome on the user's ears when worn.

[0033] Furthermore, the memory metal part 22 includes a connected plastic deformable portion 221 and an elastic portion 222. The plastic deformable portion 221 can be bent and deformed under the action of an external force to adjust the distance between the sound-emitting portion 10 and the fixing portion 30, so that it can be adjusted according to the size and shape of the user's auricle, better adapting to the natural curve and shape of the auricle and improving wearing comfort. The plastic bending deformation generated by the plastic deformable portion 221 can adjust the distance between the sound-emitting portion 10 and the fixing portion 30, so that the ear clip-type earphones 100 fit the ears more closely, reducing the risk of the earphones loosening or falling off during wearing. Users can bend and deform the plastic deformable portion 221 of the memory metal part 22 through external force according to their needs, so as to quickly and easily adjust the size of the earphones to meet the wearing needs of different users.

[0034] In some embodiments, the memory metal member 22 includes a plastically deformable portion 221 and two elastic portions 222 . The plastically deformable portion 221 is disposed between the two elastic portions 222 . The stiffness coefficient of the plastically deformable portion 221 is greater than the stiffness coefficient of the elastic portions 222 . According to Hooke's law, F=kx, where F is the elastic force of the plastically deformable portion 221 or the elastic portion 222 , k is the stiffness coefficient of the plastically deformable portion 221 or the elastic portion 222 , and x is the amount of expansion or compression of the plastically deformable portion 221 or the elastic portion 222 . If k increases while x remains unchanged, the generated force F will also increase. This means that when subjected to an external force, the plastically deformable portion 221 can withstand greater forces without deforming. In other words, when the plastically deformable portion 221 and the elastic portion 222 are subjected to the same force, the deformation amount will decrease, showing a higher anti-deformation ability, enabling the adjusted memory metal part 22 to better maintain the bent state and not return to the initial state after deformation, which helps to fine-tune the ear-clip earphones 100 to adapt to the ear shapes of different users. Users can adjust the opening size of the ear-clip earphones 100 according to the shape and size of their ears, and it is not easy to fall off after adjustment.

[0035] In some embodiments, the two elastic portions 222 are symmetrically arranged with respect to the plastically deformable portion 221, so that the elastic force provided by the elastic portions 222 on both sides is uniform, thereby reducing ear discomfort to the user caused by uneven force distribution. The length of the plastically deformable portion 221 is smaller than the length of the elastic portion 222, which helps the user to adjust the ear clip-on earphones 100 to suit their respective ear shapes. The memory metal part 22 still maintains a certain degree of elasticity and will not lose its elasticity due to excessive deformation. It maintains its original shape and is not easily damaged by fatigue, thereby providing durability of the ear clip-on earphones 100.

[0036] The two elastic portions 222 and the plastically deformable portion 221 of this embodiment are integrally formed. This integrated structure simplifies the production process, eliminating the need for separate manufacturing and assembly of components, thereby reducing assembly time and costs. Furthermore, the absence of joints or seams reduces the risk of wear and tear from daily use, thereby improving the durability of the memory metal member 22.

[0037] Exemplarily, the plastically deformable portion 221 may be a titanium alloy memory metal part obtained by heat treatment, such as a quenched portion. After quenching, the stiffness coefficient of the titanium alloy memory metal part becomes larger, that is, hardened. Hardening means that this portion is more difficult to deform. Therefore, compared with a titanium alloy memory metal part that has not been heat treated, a greater force is required to cause the same deformation, thereby changing the local characteristics of the titanium alloy memory metal part, so that the user can manually adjust the bending degree of the plastically deformable portion 221, drive the outer shell 21 to deform, and adjust the distance change between the sound-emitting portion 10 and the fixed portion 30 to adapt to ears of different sizes.

[0038] The plastically deformable portion 221 bends and deforms under the action of an external force to adjust the distance between the sound-emitting portion 10 and the fixed portion 30. It can be understood that the distance between the sound-emitting portion 10 and the fixed portion 30 can be adjusted here. Specifically, for example, when the user is not wearing the earphones, the user applies pressure to the plastically deformable portion 221 to reshape it, so that the initial distance between the sound-emitting portion 10 and the fixed portion 30 is changed. Alternatively, when the user is wearing the earphones, the user applies pressure to the plastically deformable portion 221 to reshape it, so that the sound is emitted. The wearing distance between the sound-emitting part 10 and the fixed part 30 is changed. In this way, through the coordinated use of the plastic deformable part 221 and the elastic part 222, an appropriate clamping force can be provided, and each elastic part 222 extends from the plastic deformable part 221 toward the corresponding sound-emitting part 10 or the fixed part 30, that is, it can drive the corresponding sound-emitting part 10 or the fixed part 30 to be fine-tuned, and control the opening and closing size between the sound-emitting part 10 and the fixed part 30, ensuring that the ear clip earphones 100 can be firmly fixed on the ear after adjustment, taking into account both the comfort and stability of the ear clip earphones 100.

[0039] In one embodiment, the plastically deformable portion 221 is located in the middle region in the length extension direction of the outer casing 21, which makes it convenient for users to adjust the plastically deformable portion 221 and simplifies the adjustment process. The plastically deformable portion 221 is set in the middle region and can be deformed when subjected to a certain external force, and the force can be more evenly transmitted to the elastic portions 222 at both ends, and the plastically deformable portion 221 can offset part of the rebound force of the elastic portion 222, so that the memory metal part 22 maintains the adjusted state and provides a better shape memory effect.

[0040] It can be understood that in order to further enhance the tightness of the connection between the memory metal part 22 and the sound-emitting part 10 and the fixed part 30, the elastic part 222 extends into the corresponding sound-emitting part 10 or the fixed part 30 at one end away from the plastic deformable part 221, which helps to transmit the force generated by the memory metal part 22 to the sound-emitting part 10 and the fixed part 30 at both ends, driving the sound-emitting part 10 and the fixed part 30 to move to adjust the distance between the sound-emitting part 10 and the fixed part 30, so that the ear clip earphones 100 can better fit the human ear.

[0041] To enhance the flexibility and resilience of the elastic portion 222, multiple through-holes 2221 are spaced apart on the elastic portion 222. This allows the elastic portion 222 to be flexed more flexibly, conforming more closely to the user's auricle to accommodate ears of varying shapes and sizes, providing a personalized fit for the ear clip earphone 100. Furthermore, the provision of through-holes 2221 reduces the material required for the elastic portion 222, making the connecting bridge 20 lighter and reducing pressure on the user's ear during wear, ensuring comfort even during extended wear.

[0042] Exemplarily, the through hole 2221 can be a through hole, and multiple through holes are arranged at intervals along the length direction of the elastic part 222. The through holes can reduce the concentrated stress of the elastic part 222, reduce the breakage caused by stress concentration, and extend the service life of the elastic part 222.

[0043] In one embodiment, a flexible printed circuit board 23 is further disposed within the outer cover 21. The flexible printed circuit board 23 (FPC) is a highly reliable and highly flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness, and good bendability. The outer cover 21 covers the outside of the flexible printed circuit board 23, preventing the flexible printed circuit board 23 from being exposed, thereby protecting and covering the flexible printed circuit board 23. The two ends of the flexible printed circuit board 23 are respectively connected to the speaker unit and the battery to achieve electrical connection between the speaker unit and the battery. Compared to headphones that use wires to connect the battery and the speaker unit, this simplifies wiring while also reducing the thickness of the outer cover 21 and the number of parts, which helps to reduce the production cost of the ear clip-on headphones 100. The thickness of the flexible circuit board 23 is aligned with that of the memory metal member 22. The flexible circuit board 23 deforms in response to the bending of the memory metal member 22. The parallel and spaced arrangement of the flexible circuit board 23 and the memory metal member 22 reduces contact between the two, minimizing mutual compression and wear during bending and improving the durability of the ear clip-on earphone 100. Furthermore, the memory metal member 22 may interfere with the flexible circuit board 23 in certain situations. This spacing helps minimize interference from the memory metal member 22 on the flexible circuit board 23, ensuring proper functioning of the speaker unit and battery.

[0044] For example, the flexible circuit board 23 can be set on any two opposite sides in the thickness direction of the memory metal part 22. When it is set on the side away from the sound outlet, it is convenient to maintain the flexible circuit board 23; when it is set on the side close to the sound outlet, it can utilize the space more effectively, and when the user pinches and adjusts the outer wall of the outer cover 21 when wearing it, the force first acts on the memory metal part 22 to cause it to deform, and it helps to maintain the safety and stability of the flexible circuit board 23, reducing the direct physical pressure on the flexible circuit board 23.

[0045] The outer shell 21 integrates a memory metal member 22 and a flexible circuit board 23, creating a compact layout within a limited space and achieving more efficient space utilization of the ear clip-on earphone 100. This integrated design also reduces external connection points and solder joints, improving the durability of the ear clip-on earphone 100.

[0046] The flexible circuit board 23 is composed of multiple layers of laminated printed circuits, including a lamination portion 232 and a delamination region 231. The multiple layers of printed circuits in the delamination region 231 have not been laminated, that is, the delamination region 231 includes at least two layers of delamination portions 2311 (printed circuit layers) spaced apart from each other. This maintains a delamination state, making the delamination region 231 more flexible than the lamination portion 232. The delamination region 231 is positioned opposite the plastically deformable portion 221, allowing the delamination region 231 to accommodate the larger bending angles and frequent bending of the plastically deformable portion 221 when the plastically deformable portion 221 is bent. The delamination region 231 enables the flexible circuit board 23 to withstand repeated bending of the plastically deformable portion 221, reducing breakage or damage due to material fatigue.

[0047] Furthermore, the risk of fracture in the delamination region 231 is reduced. The orthographic projection of the plastically deformable portion 221 toward the delamination region 231 is located within the delamination region 231. That is, the length of the delamination region 231 is greater than the length of the plastically deformable portion 221. This reduces stress concentration in the delamination region 231, thereby lowering the risk of fracture in the delamination region 231. Furthermore, the longer delamination region 231 provides a larger bending range, allowing the delamination region 231 to better adapt to the bending and deformation of the plastically deformable portion 221, thereby improving the reliability of the delamination region 231's bending.

[0048] The above description describes that the structural design of the connecting bridge 20 enables the ear clip type earphone 100 of the present application to have an adjustable wearing clamping force and a more comfortable wearing solution. However, the advantages of the ear clip type earphone 100 of the present application are not limited to this. Figure 4 In one embodiment, the sound-emitting portion 10 includes a first shell 11 and a second shell 12. The first shell 11 is connected to the outer shell 21, and the second shell 12 has a sound outlet (not shown). The second shell 12 is movably connected to the first shell 11 and can perform telescopic movement relative to the first shell 11 so that the user can adjust the distance between the first shell 11 and the second shell 12, so that the open earphones 100 can adjust the distance between the sound outlet and the user's ear canal opening when worn, so that the sound outlet is closer to the ear canal opening, optimize the sound transmission effect, and thereby obtain the best sound reception experience.

[0049] The speaker unit of this embodiment can be located in either the first housing 11 or the second housing 12, allowing for flexible placement of the speaker unit in the first housing 11 or the second housing 12, depending on the specific internal structural arrangement of the ear clip headphone 100. Alternatively, the speaker unit can be placed in a location that best facilitates sound transmission, based on acoustic principles or user experience. Adjustments can also be made based on the weight distribution of the ear clip headphone 100, resulting in a more balanced fit and improved wearing comfort. The ability to locate the speaker unit in either the first housing 11 or the second housing 12 provides greater flexibility and innovation in the design of the ear clip headphone 100.

[0050] Specifically, if Figures 5 to 6 As shown, the second housing 12 and the first housing 11 are slidably connected, allowing the user to easily adjust the position of the first housing 11 or the second housing 12. This is especially true for users with larger ears. Because the sound hole is too far from the user's ear canal opening, the volume of the sound emitted by the sound hole is easily too low when transmitted to the user's ear canal opening. This embodiment allows for flexible adjustment of the distance between the sound hole and the ear canal opening on the second housing 12, improving the user experience. Furthermore, the sliding connection reduces the number of parts and simplifies the manufacturing process.

[0051] In another structural form, Figure 7 As shown, the first shell 11 is spirally connected to the second shell 12, the second shell 12 is provided with an external thread, and the first shell 11 is provided with an internal thread. The first shell 11 is inserted with a thread and screwed on the second shell 12, which can provide precise adjustment. When the user feels that the volume is too small, the distance between the sound hole and the ear canal opening on the second shell 12 can be fine-tuned by rotating it, and the distance from the sound hole to the ear canal opening can be shortened by extending the second shell 12 to increase the sound.
