Description

Technical Field

[0001] This application relates to the technical field of headphones, and more particularly to an ear clip-on headphone and headphone device. Background Technology

[0002] In the field of personal audio devices, headphones, as an important audio output tool, directly affect the user's listening experience. With consumers increasingly demanding portability, comfort, and versatility in various usage scenarios, clip-on headphones, with their unique design that allows them to be worn without inserting into the ear, avoiding the discomfort of prolonged in-ear wear while maintaining adequate awareness of the surrounding environment, have become widely popular in scenarios such as sports, office work, and travel, and are gradually becoming one of the mainstream product types in the current headphone market.

[0003] However, existing mainstream clip-on headphones have significant shortcomings in audio performance, mainly due to their unique acoustic cavity design. Because clip-on headphones need to be securely held against the outside of the ear, their acoustic cavity structure is typically compact and uniquely shaped to accommodate this wearing style and ensure comfort and stability. While this design meets the wearing requirements, it negatively impacts sound propagation.

[0004] Specifically, due to the limitations of the acoustic cavity shape, the distance between the sound outlet and the ear canal in mainstream clip-on headphones is relatively far. In acoustic principles, sound waves attenuate as the distance increases during propagation; this is an unavoidable physical phenomenon. When the sound outlet is far from the ear canal, the sound waves emitted from the outlet need to travel a relatively long path through the air to reach the ear canal. During this process, the energy of the sound waves gradually dissipates, resulting in a decrease in sound intensity.

[0005] This sound wave attenuation phenomenon is particularly pronounced in the low-frequency audio range. Low-frequency sound waves have longer wavelengths, making them more susceptible to attenuation due to distance and environmental factors when propagating through the air compared to high-frequency sound waves. Therefore, current mainstream clip-on headphones, due to the distance between the sound outlet and the ear canal, cause low-frequency sound waves to be significantly attenuated by the time they reach the ear canal. This results in an inability to deliver a full and powerful low-frequency sound effect, leading to an unbalanced overall sound quality and a severe deficiency in low-frequency performance. This significantly impacts the user's complete and high-quality listening experience for music, movies, and other audio content. Utility Model Content

[0006] The purpose of this application is to provide a clip-on earphone and earphone device that can solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, this application adopts the following technical solution: On one hand, a clip-on earphone is provided, comprising: a sound cavity shell, a battery shell, and a connector, wherein the two ends of the connector are respectively connected to the sound cavity shell and the battery shell, the sound cavity shell is oval-shaped, and two speaker components are disposed inside the large end of the sound cavity shell, with the speaker openings of the two speaker components facing each other, and a sound outlet is provided at the small end of the sound cavity shell; wherein, when the clip-on earphone is worn on the ear, the sound outlet faces the ear canal opening.

[0008] Furthermore, the acoustic cavity housing is provided with a spiral sound guiding channel, one end of which is connected to the speaker port of the speaker component, and the other end of which is connected to the sound outlet.

[0009] Furthermore, when the ear clip-on headphones are worn on the ear, the long axis of the sound cavity housing is aligned with the direction of the ear canal, and the sound outlet is located along the long axis of the sound cavity housing.

[0010] Furthermore, the battery casing is oval in shape, specifically asymmetrical about its major axis. The curvature of the outer circumference of the battery casing relative to the acoustic cavity casing is α, and the curvature of the outer circumference of the battery casing away from the acoustic cavity casing is β, where α > β.

[0011] Furthermore, an angle γ is formed between the long axis of the acoustic cavity housing and the long axis of the battery housing, wherein 40°≤γ≤50°.

[0012] Furthermore, in the first direction, the small end of the battery housing is located below the small end of the acoustic cavity housing, so that an acute-angle ear inlet is formed between the small end of the acoustic cavity housing and the small end of the battery housing, allowing the ear to enter along the ear inlet and be held between the acoustic cavity housing and the battery housing.

[0013] Furthermore, in the first direction, the distance between the small end of the battery housing and the small end of the acoustic cavity housing is H, where 5mm≤H≤7mm, so that when the clip-on earphone is worn, the small end of the battery housing can contact the mastoid bone behind the ear to form support.

[0014] Furthermore, the connector is C-shaped, and its two ends are respectively connected to the large end of the battery casing and the large end of the sound cavity casing.

[0015] Furthermore, the length-to-width ratio of the battery casing is 2:1.

[0016] Furthermore, the connector includes a flexible sleeve and a shape memory metal embedded within the flexible sleeve.

[0017] On the other hand, an earphone device is also provided, including: an earphone case and ear clip-on earphones as described above, wherein the earphone case has an earphone cavity for accommodating the ear clip-on earphones.

[0018] The beneficial effects of this application are as follows: The dual speakers built into the large end are arranged in opposite directions, effectively reducing harmonic distortion through phase cancellation, resulting in a purer sound and reducing the damage of distortion to low-frequency sound quality, laying the foundation for a full and powerful low-frequency sound effect. At the same time, due to the oval shape design of the sound cavity shell, the small end can extend into the ear better, making the sound outlet of the small end closer to the ear canal, greatly shortening the sound wave propagation distance and reducing sound wave attenuation. In particular, it significantly improves the attenuation problem of low-frequency sound waves, ensuring the intensity and richness of low-frequency sound, allowing users to enjoy a more complete and high-quality audio experience. Whether it is the shock of the bass drum when listening to music or the immersive feeling of the ambient sound effects when watching movies, it can be greatly improved. Attached Figure Description

[0022] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] like Figures 1-3 As shown, this embodiment provides a clip-on earphone, including: a sound cavity shell 1, a battery shell 2, and a connector 3. The two ends of the connector 3 are respectively connected to the sound cavity shell 1 and the battery shell 2. The sound cavity shell 1 is oval in shape. Two speaker components are provided inside the large end of the sound cavity shell 1. The speaker openings of the two speaker components are arranged opposite each other. The small end of the sound cavity shell 1 is provided with a sound outlet 4. When the clip-on earphone 110 is worn on the ear, the sound outlet 4 faces the ear canal opening.

[0026] Based on the above scheme, the acoustic cavity housing 1 is designed in an oval shape, a shape carefully considered. Two speaker units are housed inside the larger end, with their speaker openings facing each other. When both speaker units operate simultaneously, the sound waves they emit interfere with each other inside the acoustic cavity. Due to the phase characteristics of sound waves, the opposing speaker openings result in a phase difference in the emitted sound waves. Through proper phase matching and interference, some harmonic distortion can be effectively canceled out. Harmonic distortion degrades the purity of sound and affects sound quality, especially low-frequency sound quality. This phase cancellation method reduces the interference of harmonic distortion on low-frequency sounds, thereby improving the quality of low-frequency sounds.

[0027] Meanwhile, the small end of the acoustic cavity shell 1 is provided with a sound outlet 4, and when the ear-clip earphone 110 is worn on the ear, the sound outlet 4 faces the ear canal opening. This design changes the situation where the sound outlet 4 of the traditional ear-clip earphone 110 is far from the ear canal, making the sound outlet 4 closer to the ear canal. After the sound waves are emitted from the sound outlet 4, they do not need to travel a long air propagation path to reach the ear canal, greatly shortening the propagation distance of the sound waves. According to the acoustic principle, the energy of sound waves attenuates with the increase of distance during propagation. The shortening of the propagation distance effectively reduces the attenuation of sound waves, allowing more sound energy to reach the ear canal, especially low-frequency sound waves, whose attenuation is significantly reduced, thereby ensuring the intensity and fullness of low-frequency sound.

[0028] Furthermore, the design of the sound outlet 4 facing the ear canal opening also achieves a directional sound transmission effect. Directional sound transmission can transmit sound more concentratedly to the ear canal, reduce the diffusion of sound into the surrounding environment, further improve the sound transmission efficiency, and allow users to hear audio content more clearly, especially the sound details in the low-frequency range.

[0029] Furthermore, the acoustic cavity housing 1 is provided with a spiral sound-guiding channel. One end of the spiral sound-guiding channel is connected to the speaker opening of the speaker, and the other end is connected to the sound outlet 4. In the field of acoustics, the characteristics and propagation effect of sound waves are affected by the propagation path during propagation. When the speaker emits sound, the sound wave enters the spiral sound-guiding channel from the speaker opening. Because the spiral sound-guiding channel is spiral-shaped, it significantly extends the propagation path of low-frequency sound waves within the acoustic cavity housing 1 compared to a straight propagation path. During sound wave propagation, low-frequency sound waves have a longer wavelength, and their energy gradually attenuates during propagation. The spiral sound-guiding channel, by extending the path, allows low-frequency sound waves more time to interact with the channel walls within the channel. The channel walls have a certain reflection and interference effect on sound waves. When low-frequency sound waves propagate within the spiral sound-guiding channel, some of the sound waves are reflected back by the channel walls, interfering with the subsequently propagating sound waves. This interference effect can adjust the phase and amplitude of low-frequency sound waves, making the energy distribution of the sound waves more uniform and reducing disordered energy loss. At the same time, the spiral structure design allows the sound waves to continuously change direction during propagation, further increasing the contact opportunities between the sound waves and the channel walls. This allows for more effective utilization of the reflection and interference effects of the channel walls on the sound waves, further optimizing the propagation characteristics of low-frequency sound waves.

[0030] Furthermore, when the ear-clamping earphone 110 is worn on the ear, the long axis of the acoustic cavity shell 1 is aligned with the direction of the ear canal, and the sound outlet 4 is located along the long axis of the acoustic cavity shell 1. From an ergonomic perspective, when the long axis of the acoustic cavity shell 1 is aligned with the direction of the ear canal, the earphone can better fit the natural shape of the ear. The human ear has a specific physiological structure, and the ear canal has its own direction. This design makes the earphone more stable when worn, reducing the displacement of the sound outlet 4 caused by earphone shaking, and ensuring the stability of sound transmission. Moreover, the smaller end of the acoustic cavity shell 1 is smaller, allowing it to extend more smoothly and deeply into the vicinity of the ear canal. This design that fits the ear makes the contact between the earphone and the ear more intimate, providing a good physical basis for accurate sound transmission. In terms of sound quality, the low-frequency sound effect is greatly improved. Because the sound outlet 4 is closer to the ear canal opening, the attenuation of low-frequency sound waves is reduced, making the low-frequency sound more powerful, full, and layered. When listening to music, users can more realistically feel the impact of bass drum beats and the richness of the bass, as if they were at a live concert, bringing a more immersive music appreciation experience. For watching movies, it also better reproduces environmental sound effects such as explosions and thunder, enhancing the consistency and realism of the audiovisual effects. In terms of sound transmission efficiency, the close proximity and precise alignment of the sound outlet 4 with the ear canal opening achieves directional sound transmission. Sound can enter the ear canal more concentratedly and efficiently, reducing sound loss and scattering during propagation, and improving sound clarity and loudness. Users don't need to turn the volume up too high to hear clear sound, which not only protects hearing but also saves battery power and extends the headphone's usage time.

[0031] In some embodiments, the battery housing 2 is oval-shaped, specifically asymmetrical about its long axis. The outer circumferential surface curvature of the battery housing 2 relative to the acoustic cavity housing 1 is α, and the outer circumferential surface curvature of the battery housing 2 away from the acoustic cavity housing 1 is β, where α > β. Ergonomically, when a user wears the clip-on earphone 110, the battery housing 2 needs to fit snugly against the back and surrounding area of ​​the ear. The tissues behind and around the ear are not perfectly symmetrical, exhibiting certain physiological curves and unevenness. The outer circumferential surface curvature α of the battery housing 2 relative to the acoustic cavity housing 1 is larger on this side, designed to better fit the more protruding area behind the ear. This larger curvature increases the contact area with the back of the ear, making the earphone more stable when worn and reducing the likelihood of displacement or falling off due to head movement or exercise. Simultaneously, this fit also distributes the pressure of the earphone on the back of the ear, preventing excessive local pressure and discomfort. The outer circumference of the battery housing 2, facing away from the sound chamber housing 1, has a relatively small curvature of β. This side is typically located near the relatively flat area at the back of the head. The smaller curvature reduces interference between the battery housing 2 and the back of the head, preventing excessive pressure on the back of the head during wear and improving comfort. Furthermore, this asymmetrical design better adapts to different users' ear shapes and head contours, as everyone's ear and head size and shape vary, increasing the headphones' versatility and fit.

[0032] Meanwhile, since the battery housing 2 needs to accommodate electronic components such as batteries while ensuring a certain level of strength and stability, the oval shape and asymmetrical design on both sides optimizes its structural strength while ensuring sufficient space inside the battery housing 2 to accommodate the electronic components. The side with a larger curvature α provides better resistance to bending and deformation because this side bears the main weight of the headphones and external forces when worn. The larger curvature can distribute these forces more evenly, reducing local stress concentration and thus extending the service life of the battery housing 2. The side with a smaller curvature β can reduce the overall weight of the battery housing 2 while ensuring structural stability, making the headphones lighter and further improving wearing comfort.

[0033] It is worth mentioning that an angle γ is formed between the long axis of the acoustic cavity housing 1 and the long axis of the battery housing 2, where 40°≤γ≤50°. When a user wears the clip-on earphone 110, the acoustic cavity housing 1 needs to precisely align the sound outlet 4 with the ear canal opening to ensure that the sound can be transmitted to the ear efficiently and accurately. The battery housing 2 undertakes the important task of providing stable support for the earphone; it must fit well against the back and surrounding areas of the ear to prevent the earphone from shaking or falling off during wear.

[0034] Extensive experiments and human data research have revealed that a 40° to 50° angle between the long axis of the acoustic cavity housing 1 and the long axis of the battery housing 2 perfectly balances the two key requirements of aligning the sound outlet 4 with the ear canal opening and providing stable support for the battery housing 2. Within this angle range, the acoustic cavity housing 1 naturally conforms to the contour of the front of the ear, placing the sound outlet 4 precisely in the optimal position to align with the ear canal opening, like a custom-designed acoustic channel entrance for the ear. Simultaneously, the battery housing 2 fits snugly against the back of the ear at a suitable angle, its long axis matching the physiological curve of the back of the ear, forming a stable support structure, like providing a stable fulcrum for the headphones on the ear.

[0035] In this design, in the first direction, the smaller end of the battery housing 2 is located below the smaller end of the acoustic cavity housing 1, forming an acute-angled in-ear position 5 between the two. The ear can then enter through this in-ear position 5 and be held between the acoustic cavity housing 1 and the battery housing 2. When a user wears headphones, there needs to be a natural, smooth, and physiologically compatible way to secure the headphones to the ear. This design, by positioning the smaller end of the battery housing 2 below the smaller end of the acoustic cavity housing 1 in the first direction to form the acute-angled in-ear position 5, fully considers the shape of the ear and wearing habits. This acute-angled in-ear position 5 provides a clear and natural guiding direction for the ear, essentially designing a dedicated channel for the ear to enter the headphone holding area. Users simply need to gently insert their ear along the acute-angle in-ear position 5. The sound cavity shell 1 is designed to slide smoothly along the natural contour of the auricle until it precisely reaches the concha cavity. At the same time, it allows the ear to naturally enter between the sound cavity shell 1 and the battery shell 2 without complicated adjustments, greatly improving the convenience and comfort of wearing.

[0036] Furthermore, connector 3 employs a special structure and materials, possessing elastic deformation characteristics. When the acoustic cavity shell 1 begins to slide, connector 3 is in a relatively relaxed state. As the acoustic cavity shell 1 gradually approaches the concha, connector 3 is compressed by the changing relative position between the auricle and the battery shell 2, and begins to undergo elastic deformation. This elastic deformation is not instantaneous but rather a gradual process, resulting in a gradual change in the clamping force generated by connector 3 from 3N to 5N. When the acoustic cavity shell 1 finally reaches the concha and is stably positioned, the elastic deformation of connector 3 reaches a relatively stable state, at which point the 3N-5N clamping force can securely hold the earphone in place on the ear.

[0037] Specifically, in the first direction, the distance H between the small end of the battery housing 2 and the small end of the acoustic cavity housing 1 is 5mm ≤ H ≤ 7mm, so that when the ear-clamping headphones 110 are worn, the small end of the battery housing 2 can contact the mastoid bone behind the ear to form support. Because the small end of the battery housing 2 can precisely contact the mastoid bone behind the ear to form support, the headphones are as stable as if they were nailed to the ear after being worn. Whether the user is walking, going up and down stairs, or engaging in strenuous exercise such as running or fitness, the headphones will always remain in the correct position without shaking, shifting, or falling off. This stable wearing effect not only ensures that the user can continuously and clearly hear the audio content, avoiding the inconvenience of interrupting use due to the headphones falling off, but also reduces noise interference caused by headphone shaking, improving the overall audio experience. Moreover, the distance value of 5mm to 7mm is carefully optimized to ensure that the battery housing 2 effectively contacts the mastoid bone behind the ear to form support without causing excessive pressure on the mastoid bone. If the distance is too small, the battery housing 2 may put excessive pressure on the mastoid bone behind the ear, causing pain and discomfort; if the distance is too large, it will not provide effective support, resulting in unstable earphone wear. This suitable distance range allows the earphones to fit naturally in the ear when worn, reducing local pressure. Even if users wear the earphones for a long time, they will not feel ear pain, numbness, or fatigue, truly achieving a perfect balance between comfortable wear and stable support.

[0038] Generally, the connector 3 is C-shaped, with its two ends connected to the large end of the battery housing 2 and the large end of the sound cavity housing 1, respectively. This represents a significant leap forward in wearing comfort. The flexibility and elasticity of the C-shaped connector 3 allow it to adaptively adjust to different ear shapes, acting like a thoughtful ear companion that perfectly fits every unique ear contour. Compared to traditional rigid connectors 3, it does not cause excessive pressure or restriction on the ear, reducing discomfort such as pain and numbness caused by prolonged wear. Users can fully enjoy music, calls, or other audio content without worrying about discomfort from the headphones, truly achieving a perfect combination of comfortable wearing and long-term use.

[0039] From a stability perspective, the C-shaped connector 3 wraps around the outside of the ear, forming a stable surround structure that effectively prevents the earphones from shaking or falling out during wear. Whether the user is walking, going up and down stairs, or engaging in strenuous exercise such as running or working out, the earphones remain firmly fixed on the ear and will not shift due to head movements or external interference. This stable fit not only ensures continuous and clear audio transmission, allowing users to fully immerse themselves in the audio world, but also avoids the risk of damage caused by the earphones falling out, saving users the cost of repairing or replacing earphones.

[0040] In terms of aesthetics and style, the C-shaped connector 3 plays a crucial role. Its smooth curves and unique shape add a touch of technology and fashion to the headphones, making them more visually appealing. Compared to traditional straight or simple connection structures, the C-shaped connector 3 makes the headphones look more refined and dynamic, meeting the aesthetic demands of modern consumers. Whether used in business settings or for leisure, these headphones can become part of the user's fashionable outfit, showcasing their personality and taste.

[0041] Meanwhile, the connector 3 includes a flexible sleeve and shape memory metal embedded within the flexible sleeve. The flexible sleeve is typically made of materials with good flexibility and skin-friendliness, such as silicone. Silicone is soft and elastic, providing a gentle and comfortable feel when in direct contact with human skin, effectively reducing friction and irritation to the ear skin and avoiding allergic or uncomfortable reactions due to prolonged wear. It also has a certain cushioning performance; when the earphone is subjected to external impact or pressure, the flexible sleeve can absorb some energy, reducing damage to the internal shape memory metal and other components. Shape memory metal is a special material with a unique shape memory effect. During manufacturing, shape memory metal is given a specific initial shape. When the connector 3 is in its initial state, the shape memory metal maintains a pre-set bent or stretched shape, providing basic structural support for the earphone. When the user wears the earphone, the shape and size of the ear exert a certain external force on the connector 3, causing the shape memory metal to elastically deform. However, the unique feature of shape memory metal is that it can recover its original shape within a certain temperature range (usually close to human body temperature). This characteristic allows the connector 3 to automatically adjust its shape according to the contour of the ear, achieving a personalized fit. For example, when a user wears the headphones on their ears, the memory metal gradually deforms according to the curvature of the ear and the distribution of pressure until it fits the ear perfectly, just like it was custom-made for the user's ears.

[0042] Optionally, the length-to-width ratio of the battery housing 2 is 2:1, which closely matches the contour of the human ear and wearing habits. The human ear has a certain curvature and spatial distribution; as an important component of the earphone, the battery housing 2 needs to fit naturally with the ear to provide a comfortable wearing experience. The elongated battery housing 2 better conforms to the curve of the ear, extending along the outer contour of the ear, reducing abrupt contact and friction with the ear. At the same time, this proportion makes the space occupied by the battery housing 2 on the ear more reasonable; it is neither too wide to squeeze the ear and cause discomfort, nor too narrow to provide sufficient support and cause the earphone to be unstable. It's like a custom-made accessory for the ear, perfectly integrating into the ear's space, so that the user can hardly feel its presence when wearing it.

[0043] On the other hand, such as Figure 4 , Figure 5 As shown, an earphone device is also provided, including: an earphone case 120 and an ear clip-on earphone 110 as described above, wherein the earphone case 120 is provided with an earphone cavity for accommodating the ear clip-on earphone 110.

[0044] From the perspective of combining biomimicry and ergonomics, the earphone charging case 120's design, featuring a stacked shape reminiscent of natural pebbles, demonstrates profound design wisdom. Pebbles, sculpted by flowing water over time, develop a rounded, smooth shape that conforms to the human hand's grip. The earphone charging case 120 borrows this form; its rounded curves perfectly fit the curvature of the palm, providing a comfortable feel whether picking up or placing the case, reducing the discomfort caused by sharp edges and enhancing the user experience. Furthermore, this stacked design is ingenious in its space utilization, rationally planning the various parts of the earphone charging case 120 within a limited space, resulting in a more compact overall structure that is both portable and space-saving.

[0045] Inside the earphone case 120, the independent left and right ear chambers are connected and secured by a magnetic device. The magnetic force generated by the device ensures that the left and right ear chambers fit tightly when closed, forming a sealed and stable space that effectively protects the clip-on earphones 110 from external dust, impacts, and other damage. When the user needs to remove or insert the earphones, simply apply appropriate external force to overcome the magnetic force to easily open or close the earphone case 120. The operation is simple and convenient, eliminating the need for complicated opening and closing actions and greatly improving efficiency.

[0046] Furthermore, the left and right earphone motherboards are arranged in a mirror image, primarily to achieve symmetry and consistency in earphone functions, and to provide a basis for the normal operation of the Hall sensors. A Hall sensor is a magnetic sensor based on the Hall effect; it can sense changes in magnetic fields and convert them into electrical signals. In the earphone design, magnets and Hall sensors are respectively placed at specific locations in the earphone housing 120 and on the earphone motherboard.

[0047] When a user wears headphones, the position and orientation of the headphones change, causing a change in the magnetic field distribution around them. Hall effect sensors detect these magnetic field changes in real time and transmit the detected signals to the headphone's control system. The control system determines whether the headphones are worn correctly based on the received signals. If the wearing orientation is correct, the headphones will function normally; if the wearing orientation is incorrect, the control system will trigger a beeping reminder function, emitting a beeping sound through the headphone's internal speaker to inform the user to adjust the wearing orientation. This solves the control problems that might arise from non-universal designs, ensuring that users can use the headphones correctly and obtain the best audio experience.
