Description

Clip-on headphones

[0001] This application claims priority to Chinese Patent Application No. 202422145140X, filed with the State Intellectual Property Office of China on September 2, 2024, entitled "Ear Clip Headphones", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of headphone technology, and in particular to a clip-on headphone. Background Technology

[0003] In related technologies, ear clip headphones typically adopt an integrated U-shaped or C-shaped ear clip structure. This ear clip structure deforms to form a clamping force, thereby allowing the headphones to be worn on the user's ear by clamping the user's auricle. However, this clamping method tends to make the wearing stability of ear clip headphones poor. Summary of the Invention

[0004] This application provides an ear clip-on earphone that can improve the stability of the ear clip-on earphone when worn.

[0005] This application provides an ear clip-on earphone, which includes a first earphone body, at least two second earphone bodies, and a connecting bridge; the first earphone body is configured to be worn on the front side of the ear and has a sound outlet; the at least two second earphone bodies are configured to be worn on the back side of the ear; the connecting bridge connects the first earphone body and the second earphone bodies.

[0006] Based on the ear clip-on headphones of this application embodiment, at least two second earpieces are provided. When worn, at least two second earpieces can provide multi-point support behind the ear. While ensuring support stability, the volume of each second earpiece can also be made smaller, thereby avoiding the pressure caused by a single heavy second earpiece placed behind the ear. This can reduce the discomfort caused by wearing for a long time, improve the wearing stability and comfort, and thus improve the user wearing experience. Attached Figure Description

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Headphones, as a common electronic product, play an important role in people's lives. They receive electrical signals from media players or receivers and convert them into audible sound waves using speakers placed close to the ears. This allows for private listening without disturbing others, and also isolates ambient noise, which is helpful for people using headphones in noisy environments such as recording studios, DJing, traveling, or exercising. Headphones can be categorized by their sound generation mechanism, including air conduction headphones and bone conduction headphones. They can also be distinguished by their wearing style, including over-ear headphones, ear-hook headphones, and clip-on headphones.

[0022] In related technologies, clip-on headphones employ an integrated U-shaped or C-shaped clip structure. This clip structure deforms to create a clamping force, allowing the headphones to be worn on the user's ear by clamping it against the auricle. However, this two-point clamping structure on the front and back of the ear results in concentrated clamping force on both sides of the ear, which can exacerbate ear discomfort during prolonged wear.

[0023] To address the aforementioned issues, please refer to Figures 1 to 3. This application proposes an ear clip-on earphone 1. In the embodiments of this application, the ear clip-on earphone 1 includes a first earphone body 10, a speaker unit, a second earphone body 20, and a connecting bridge 30.

[0024] The first earphone body 10 is provided with a sound outlet 111, and a speaker unit is housed inside the first earphone body 10. The speaker unit is configured to convert electrical signals into sound signals and transmit the sound signals to the outside through the sound outlet 111. The speaker unit can be a microelectromechanical speaker, a moving coil speaker, or a moving iron speaker, etc.

[0025] When wearing the ear clip-on earphone 1, the first earphone body 10, which houses the speaker unit, is usually worn in front of the ear, i.e., inside the concha. This allows for listening without completely blocking the ear canal, and the first earphone body 10 does not need to be fixed by squeezing the tragus. Instead, the second earphone body 20, which does not have a speaker unit, is worn in the back of the ear. The connecting bridge 30 connects the first earphone body 10 and the second earphone body 20, and the first earphone body 10 and the second earphone body 20 can be clamped and fixed in front of and behind the ear, respectively.

[0026] In some embodiments, at least two second earphone bodies 20 are provided. In this way, when worn, at least two second earphone bodies 20 can provide multi-point support behind the ear. While ensuring support stability, the volume of each second earphone body 20 can also be made smaller accordingly, thereby avoiding the pressure caused by a single heavy second earphone body 20 placed behind the ear. This can reduce the discomfort caused by wearing for a long time, improve the wearing stability and comfort, and thus improve the user wearing experience.

[0027] Since there are at least two second earphone bodies 20, the functional elements of the ear clip-on earphone 1 can be housed in different second earphone bodies 20, so that the volume of each second earphone body 20 can be smaller than the volume of the first earphone body 10, and the overall volume of the first earphone body 10 can also be reduced accordingly. This makes the weight of the first earphone body 10 worn on the front of the ear lighter, ensuring wearing comfort, and making it more compact and flexible in appearance, thus improving aesthetics.

[0028] Furthermore, there can be two second earphone bodies 20. This can reduce the overall size and weight of the ear clip earphone 1 while ensuring a stable fit, making the ear clip earphone 1 lighter, more comfortable to wear, and with lower manufacturing costs. There can also be multiple second earphone bodies 20, which can greatly improve the stability of the ear clip earphone 1 when worn.

[0029] The connecting bridge 30 has various structures. For example, the connecting bridge 30 includes a first connecting end 311 and at least two second connecting ends 312. The first connecting end 311 is connected to the first earphone body 10, and a second connecting end 312 is connected to a second earphone body 20.

[0030] When there are two second earphone bodies 20, and the two second earphone bodies 20 are spaced apart from each other, the corresponding connecting bridge 30 has two second connecting ends 312, which are connected to each other respectively, as shown in Figure 2. The first connecting end 311 and the two second connecting ends 312 can be roughly formed into a "Y"-shaped bifurcated structure to achieve a three-point support fixing form. It can be understood that the "Y"-shaped connecting bridge 30 can be an integral structure.

[0031] When worn, both second earphone bodies 20 are located behind the user's ears. This disperses the stress concentration of the second earphone bodies 20 behind the user's ears, reducing discomfort. Furthermore, the two second earphone bodies 20, together with the first earphone body 10 worn in front of the user's ears, clamp and fix the user's ears, thus achieving a three-point fixation method, making the wearing more stable and less prone to loosening.

[0032] Of course, when there are multiple second earphone bodies 20, there can also be multiple second connection ends 312 that are connected to the multiple second earphone bodies 20. For example, the specific number can be 3 or 4. In this case, the connecting bridge 30 can be roughly formed into a fan-shaped structure to achieve multi-point support and improve the stability of the ear clip earphone 1 when worn. Alternatively, the connecting bridge 30 can also be formed into other structural forms. Furthermore, the connecting bridge 30 can be a one-piece molded structure, which can improve its structural strength, ensure the stability of the connection, and reduce the production cost. Of course, the connecting bridge 30 can also be set separately. This application does not limit this.

[0033] For example, the connecting bridge 30 includes at least two sub-bridges 31, each sub-bridge 31 having a first connecting end 311 and a second connecting end 312. The first connecting end 311 is connected to the first earphone body 10, and the second connecting end 312 is connected to the second earphone body 20.

[0034] When two second earphone bodies 20 are provided, spaced apart from each other, the connecting bridge 30 has two sub-bridges 31, and the two second earphone bodies 20 are respectively connected to the second connecting ends 312 of the two sub-bridges 31. In the wearing state, the two sub-bridges 31 extend from the front of the user's ear to the back of the user's ear, allowing the two second earphone bodies 20 to clamp and fix the user's ear against the first earphone body 10 at the front of the user's ear from the back of the ear, thus achieving a three-point fixation method and improving wearing stability. Of course, multiple second earphone bodies 20 can also be provided. In this case, multiple sub-bridges 31 are also provided, with a number equivalent to the number of second earphone bodies 20. Each second earphone body 20 is connected to the second connecting end 312 of each sub-bridge 31, thus achieving multi-point fixation and further improving wearing stability.

[0035] In some embodiments, the spacing between at least two second earphone bodies 20 is adjustable, allowing the user to adjust the spacing of the second earphone bodies 20 behind the ear to accommodate different ear sizes and shapes. This ensures the ear-clip headphones 1 are securely worn on the user's ear, reducing the risk of the headphones falling off during use. Furthermore, because there are at least two second earphone bodies 20 with a spacing between them, determining the position of each second earphone body 20 behind the ear during wear can be inconvenient. Adjustable spacing between the at least two second earphone bodies 20 allows adjacent second earphone bodies 20 to move closer or further apart, making it easier for the user to wear the ear-clip headphones 1.

[0036] In one possible implementation, the first connecting end 311 of the sub-bridge 31 is rotatably connected to the first earphone body 10, so that the distance between two adjacent second earphone bodies 20 is adjustable. For example, Figure 3 is a schematic diagram of the structure when the second connecting ends 312 of two adjacent sub-bridges 31 are far apart. At this time, the ear clip-on earphone 1 is in its initial state where the distance between the two adjacent second earphone bodies 20 is not adjusted. From the perspective of the figure, the distance between the two adjacent second earphone bodies 20 is L1, which can refer to the initial distance between the two adjacent second earphone bodies 20. The user can apply force to the two adjacent sub-bridges 31 to bring them closer together, thereby bringing the two adjacent second earphone bodies 20 closer together until they abut against each other. Figure 4 shows the position of the two adjacent second earphone bodies 20 after adjustment. At this time, the two adjacent second earphone bodies 20 abut against each other, making L1 0mm. The specific value of L1 can be set according to the applicable scenario; that is, L1 can be set to 3mm, 4mm, 5mm, etc., and this application does not limit this.

[0037] Specifically, during the wearing process, the user can pinch the two adjacent sub-bridges 31. The force on the sub-bridges 31 causes their first connecting end 311 to rotate and connect with the first earphone body 10. At this time, the corresponding second earphone bodies 20 connected to the second connecting end 312 move closer to each other, making it easier for the user to wear the ear clip-on earphone 1. After that, the user can release the two adjacent sub-bridges 31. The second connecting ends 312 of the two sub-bridges 31 move away from each other, and the second earphone bodies 20 located behind the ear and close to each other move away from each other accordingly, and are firmly pressed against the back of the ear. Together with the first earphone body 10 worn in front of the ear, they clamp the ear. This achieves a multi-point clamping form after wearing, which has high structural stability and is convenient and quick to wear. The pressure of the second earphone body 20 behind the ear is more evenly distributed, reducing the pressure on the ear and reducing the discomfort caused by wearing for a long time, thus improving the user's wearing experience.

[0038] In addition, the ear clip-on earphone 1 also includes an elastic element, which can be in the form of a torsion spring, a spring, etc. The elastic element connects the first connecting end 311 and the first earphone body 10. During the rotational connection between the first connecting end 311 of the subbridge 31 and the first earphone body 10, the elastic element can use the force of elastic deformation to drive the second connecting ends 312 of the two adjacent subbridges 31 away from each other.

[0039] Alternatively, the two ends of the elastic element are respectively connected to two adjacent sub-bridges 31 and located between the first connecting end 311 and the second connecting end 312. During the rotational connection between the first connecting end 311 of the sub-bridge 31 and the first earphone body 10, when the ear clip earphone 1 is worn on the user's ear, the elastic element can drive the second connecting ends 312 of the two adjacent sub-bridges 31 to move away from each other, so that the two adjacent second earphone bodies 20 move away from each other. Through the first earphone body 10 and the two mutually separated second earphone bodies 20, they are clamped together on the front and back sides of the user's ear, so that the ear clip earphone 1 can be quickly and stably clamped on the user's ear, thereby improving the user's wearing experience.

[0040] In another possible implementation, the ear-clip earphone 1 also includes magnetic components. At least two magnetic components can be provided, and the at least two magnetic components are respectively provided on two adjacent sub-bridges 31. When the magnetic components are magnets of the same polarity, during the rotational connection between the first connecting end 311 of the sub-bridge 31 and the first earphone body 10, the two magnets of the same polarity repel each other, which can drive the second connecting ends 312 of the two adjacent sub-bridges 31 to move away from each other, so that the two adjacent second earphone bodies 20 are moved away from each other and are in a clamping position. The ear-clip earphone 1 can thus be quickly and stably clamped to the user's ear, improving the stability when wearing it; or, at least two magnetic components can also be respectively provided on two adjacent second earphone bodies 20, which can also achieve the above effect, improve the stability when wearing it, and thus improve the user's wearing experience.

[0041] In another possible implementation, the first connecting end 311 of the subbridge 31 is fixedly connected to the first earphone body 10, and the subbridge 31 is elastic, capable of driving the second connecting ends 312 of two adjacent subbridges 31 to move away from each other, and the distance between two adjacent second earphone bodies 20 is L1. Therefore, the material of the subbridge 31 can be, but is not limited to, silicone, rubber, ABS, PC, PP, etc., which have very good elasticity and excellent flexibility, allowing the subbridge 31 to have good deformation performance. Specifically, during the wearing process, the user can also pinch the two adjacent sub-bridges 31. Due to their elasticity, the second connecting ends 312 of the sub-bridges 31 move closer to each other under force. The second earphone bodies 20 connected to the second connecting ends 312 then move closer to each other until they abut against each other. At this time, L1 is 0mm, which makes it convenient for the user to wear the ear clip-on earphone 1. After that, the user can release the two adjacent sub-bridges 31. The second connecting ends 312 of the two sub-bridges 31 will move away from each other and return to their original position due to their elasticity. The second earphone bodies 20 located behind the ear and close to each other will move away from each other accordingly. This can also achieve the effect of convenient wearing and enhanced structural stability.

[0042] The first connecting end 311 of the sub-bridge 31 is retractable relative to the first earphone body 10, so that the length of the connecting bridge 30 between the first earphone body 10 and the second earphone body 20 is adjustable. This allows the ear clip-on earphone 1 of this application to be adapted to users with different ear sizes. Referring to Figures 5 and 6, in some embodiments, the first earphone body 10 includes an ear shell 11 and a slider 12. The ear shell 11 houses a speaker unit and has a sound outlet 111. The material of the ear shell 11 can be plastic, silicone, etc. The shape of the ear shell 11 can be the same as or different from the shape of each second earphone body 20, and their volumes can also be the same or different. For example, the ear shell 11 can be an approximately spherical structure to adapt to the shape of the concha, while the second earphone body 20 can be an irregular structure with an arc-shaped outer wall to increase the contact area with the back of the ear, thereby improving wearing stability. This application does not limit this.

[0043] The earpiece 11 is also provided with a groove 112, which has an opening 1121 communicating with the outside. The slider 12 can be disposed in the groove 112 and slide in cooperation with it, and can slide in the depth direction of the groove 112. The first connecting end 311 extends into the groove 112 through the opening 1121 and connects with the slider 12. Specifically, during wearing, the user can pull the first connecting end 311 to drive the slider 12 to slide in the depth direction of the groove 112, thereby adjusting the length of the first connecting end 311 extending into the groove 112 through the opening 1121, and thus adjusting the length of the connecting bridge 30 between the first earphone body 10 and the second earphone body 20. In order to prevent the slider 12 from falling out of the groove 112 during sliding in the depth direction of the groove 112, a limiting part is also formed on the groove wall of the groove 112. The limiting part is formed at the opening 1121 and can stop and limit the slider 12 during the sliding cooperation between the slider 12 and the groove 112. The specific structural form of the limiting part can be that it is arranged around the periphery of the opening 1121 and has the same shape as the opening 1121, or it can be different. Alternatively, the structural form of the limiting part can also be a block structure. This application does not limit this.

[0044] In addition, a damping element (not shown in the figure) is provided between the outer wall of the slider 12 and the groove wall of the slide 112. This element provides damping force during the sliding engagement of the slider 12 and the slide 112. With this design, after the slider 12 slides to the appropriate position, the damping force can relatively fix the outer wall of the slider 12 and the groove wall of the slide 112, effectively reducing the possibility of accidental movement of the slider 12 due to accidental touch or collision during use. This ensures stability and consistency, and improves stability during wear. Furthermore, the damping force also allows users to adjust the clamping force of the ear clip-on headphones 1 more smoothly and stably, further improving the stability of the ear clip-on headphones 1 during wear.

[0045] To facilitate the installation of the damping element between the outer wall of the slider 12 and the groove wall of the slide 112, the damping element can be a damping ring. An installation groove is also provided on the outer wall of the slider 12 or the groove wall of the slide 112, and the damping ring is nested within the installation groove. In some other embodiments, the damping element can also be injection molded onto the outer wall of the slider 12. In this embodiment, the damping element can be block-shaped or ring-shaped. This application does not limit the specific installation method of the damping element. Furthermore, the material of the damping element can include, but is not limited to, rubber, silicone, polyurethane, etc.

[0046] Referring again to Figures 4 to 6, in some embodiments, the earcup-style earphone 1 further includes a battery 21 and an electronic control board 22. The battery 21 provides power to the speaker unit and the electronic control board 22, and the electronic control board 22 is electrically connected to the battery 21 and the speaker unit. The battery 21 and the electronic control board 22 are respectively housed in different second earphone bodies 20, which can make the second earphone body 20 smaller and reduce production costs.

[0047] Specifically, at least two batteries 21 are provided, with one battery 21 housed within a second earphone body 20. The second earphone body 20 with the battery 21 is detachably connected to the second connecting end 312, facilitating battery replacement and improving the battery life of the ear clip-on earphone 1. The detachable form of the second earphone body 20 and the second connecting end 312 may include, but is not limited to, snap-fit ​​or screw-fit, etc., and this application does not limit this. For example, a slot may be provided on one of the second connecting end 312 or the second earphone body 20, and a buckle may be provided on the other. The slot and the buckle engage to snap the second earphone body 20 to the second connecting end 312, thereby achieving a detachable connection between the second earphone body 20 with the battery 21 and the second connecting end 312.

[0048] It should be noted that, in order to ensure that the battery 21 can quickly connect to other components to ensure power supply when the second earphone body 20 is detachably connected to the second connection end 312, a terminal block is also provided on the second connection end 312. The terminal block is plugged into the battery 21, so that the battery 21 can provide stable power supply and improve the convenience of detachable connection between the second earphone body 20 and the second connection end 312.

[0049] In some embodiments, in order to further achieve a more comfortable clamping force on the ear with the ear clip 1 and improve the user's wearing experience while ensuring structural stability, the ear clip 1 also includes a memory metal wire 50. The memory metal wire 50 can be installed on the subbridge 31, thereby enabling the subbridge 31 to have a rebound force, which makes it convenient and effortless to adjust the distance between two adjacent second earpieces 20.

[0050] It should be noted that the memory metal wire 50 is made of an alloy with memory properties, typically composed of materials such as nickel, titanium, platinum, copper, and silver. The memory metal wire 50 possesses high elasticity, wear resistance, and stability, allowing it to maintain its original shape and performance under different temperature and humidity conditions. This ensures appropriate pressure between the first earphone body 10 and the second earphone body 20 and the ear during wear, making the ear-clip earphone 1 more securely fixed around the ear and less prone to loosening or shifting. Furthermore, the memory metal wire 50 has high elasticity and durability, better adapting to different users' ear sizes to meet their diverse needs. It can also withstand prolonged stretching and compression without easily deforming or fatigued, extending the lifespan of the ear-clip earphone 1.

[0051] In some embodiments, the ear clip-on earphone 1 further includes a conductive wire 40, which is electrically connected to the battery 21, the electronic control board 22, and the speaker unit. The conductive wire 40 passes through the connecting bridge 30 and is curved, which is beneficial to the compactness and aesthetics of the overall structure. Of course, in some other embodiments, a wiring groove can also be provided on the outer wall of the connecting bridge 30, through which the conductive wire 40 is connected to the battery 21, the electronic control board 22, and the speaker unit respectively. This application is not limited to this.

[0052] It should be noted that the aforementioned shape memory metal wire 50 and conductive wire 40 are arranged in parallel. "Parallel arrangement" means that the shape memory metal wire 50 and conductive wire 40 extend in the same direction and are spaced apart from each other. This arrangement maintains a distance between the shape memory metal wire 50 and the conductive wire 40, preventing them from crossing or tangling, and resulting in a more rational spatial layout for the ear-clip earphone 1. Furthermore, while providing elasticity to the connecting bridge 30, the shape memory metal wire 50 also provides some support for the connecting bridge 30. When the ear-clip earphone 1 is subjected to external pressure, the shape memory metal wire 50 can protect the conductive wire 40 from risks such as pulling or bending.
