Description

Technical Field

[0001] This utility model relates to the field of headphone equipment technology, and in particular to a wireless headphone. Background Technology

[0002] Headphones are widely used in people's daily lives, working with electronic devices such as mobile phones and computers to provide users with an auditory feast. Headphones receive electrical signals from media players or receivers and convert them into audible sound waves using speakers placed close to the ears. With advancements in wireless communication technology and increasing consumer demand for portable audio devices, wireless headphones have become a mainstream audio product. Traditional wireless headphones are mainly divided into in-ear, semi-in-ear, and over-ear types. In-ear headphones rely on ear tips for stability, while over-ear headphones are held in place by a headband and earcups. However, these designs still have some problems. For example, in-ear headphones can cause ear canal discomfort after prolonged wear and are prone to falling out during exercise; semi-in-ear headphones have poor stability and are not stable enough during strenuous exercise (such as running or fitness); and over-ear headphones are bulky, less portable, and unsuitable for use in hot environments. However, existing ear-hook headphones still have many shortcomings. For example, rigid ear hooks cannot adapt to different users' ear shapes, resulting in poor wearing comfort; elastic ear hooks can provide a certain clamping force, but they are prone to deformation after long-term use, resulting in decreased stability; and ear-hook headphones have unreasonable internal wiring designs, which affect signal transmission or increase the weight of the headphones, reducing the user experience.

[0031] Headphones are widely used in people's daily lives, working with electronic devices such as mobile phones and computers to provide users with an auditory feast. Headphones receive electrical signals from media players or receivers and convert them into audible sound waves using speakers placed close to the ears. With advancements in wireless communication technology and increasing consumer demand for portable audio devices, wireless headphones have become a mainstream audio product. Traditional wireless headphones are mainly divided into in-ear, semi-in-ear, and over-ear types. In-ear headphones rely on ear tips for stability, while over-ear headphones are held in place by a headband and earcups. However, these designs still have some problems. For example, in-ear headphones can cause ear canal discomfort after prolonged wear and are prone to falling out during exercise; semi-in-ear headphones have poor stability and are not stable enough during strenuous exercise (such as running or fitness); over-ear headphones are bulky, have low portability, and are not suitable for use in hot environments. To improve wearing stability, ear-hook wireless headphones have emerged on the market, which use an ear hook structure to wrap around the ear to enhance the fixation effect. However, existing ear-hook headphones still have many shortcomings. For example, rigid ear hooks cannot adapt to different users' ear shapes, resulting in poor wearing comfort; elastic ear hooks can provide a certain clamping force, but they are prone to deformation after long-term use, resulting in decreased stability; and ear-hook headphones have unreasonable internal wiring designs, which affect signal transmission or increase the weight of the headphones, reducing the user experience.

[0032] refer to Figures 1-10 To address the aforementioned issues, this application provides a wireless earphone 10, comprising a first housing 20, an ear hook 30, and an ear clip assembly 40. The first housing 20 is connected to the ear hook 30 and is used to mount a speaker. The ear clip assembly 40 includes a first connector 41, an elastic member 42, and a second connector 43 sequentially connected in the extending direction of the ear hook 30. The first housing 20 has a first receiving groove 21, a portion of the first connector 41 is disposed within the first receiving groove 21, and the elastic member 42 and the second connector 43 are disposed within the ear hook 30.

[0033] The wireless earphone 10 includes a first housing 20, an ear hook 30, and an ear clip assembly 40. The specific shape of the wireless earphone 10 can adopt an innovative ergonomic design, ensuring high-quality sound while providing a more snug and secure wearing experience. Wireless earphones are suitable for various scenarios, and ear clip-on earphones offer a more comfortable wearing experience compared to traditional earphones. A speaker is installed inside the first housing 20; in some embodiments, a high-fidelity speaker can be used to play the sound. The first housing 20 adopts an ergonomic streamlined design, naturally conforming to the ear's contours for a comfortable wearing experience. In some embodiments, a first receiving groove 21 is formed in the first housing 20, and a portion of the first connecting member 41 is disposed within the first receiving groove 21 to fix part of the ear clip assembly 40 structure, ensuring the overall structural stability of the wireless earphone 10.

[0034] See Figure 2 and Figure 4 The ear hook 30 is connected to the first housing 20. In some embodiments, the ear hook 30 can be naturally bent to adapt to different user ear shapes. The interior of the ear hook 30 may have a hollow design to accommodate the components of the ear clip assembly 40. Simultaneously, designing the interior of the ear hook 30 as a hollow structure can reduce its weight, ensuring structural strength while maintaining a lightweight feel for the user. One end of the ear hook 30 is securely connected to the first housing 20, and the other end extends to the back of the ear, forming a wraparound support, ensuring the headphones remain stable and do not easily fall off during exercise or daily activities. In some embodiments, the curvature of the ear hook 30 is ergonomically designed, allowing the ear hook 30 of the wireless headphones 10 to naturally conform to the curve of the ear, avoiding additional pressure on the ear and thus improving the user's comfort when wearing the headphones. In some implementations, the ear hook 30 can be made of silicone. The ear hook 30 encloses the ear clip assembly 40, solving the problem of the inability to securely connect the flexible silicone component to the rigid component. While flexible silicone provides elasticity, it cannot firmly connect the rigid components at both ends. Alternatively, completely enclosing the rigid component with flexible silicone or using only the rigid component results in poor overall elasticity. The ear hook 30 enclosing the ear clip assembly 40 ensures both the overall aesthetics of the wireless earphone 10 and effective protection for the ear clip assembly 40. The elastic properties of the silicone material, combined with the mechanical structure of the ear clip assembly 40, provide sufficient support while maintaining a flexible wearing experience. Furthermore, the surface of the silicone ear hook 30 can be treated with an anti-slip finish to ensure a stable fit even when the user sweats during exercise. Silicone material has excellent anti-aging properties, resisting deformation or yellowing over long-term use, thus extending the lifespan of the wireless earphone 10.

[0035] See Figures 5-7The ear clip assembly 40 is composed of three parts connected in sequence: a first connector 41, an elastic element 42, and a second connector 43. Part of the first connector 41 is embedded in the first receiving groove 21 of the first housing 20, and a portion of the first connector 41 is disposed within the first receiving groove 21. The elastic element 42 and the second connector 43 are disposed within the ear hook 30, ensuring a reliable and fixed connection between the ear clip assembly 40 and the first housing 20, preventing loosening during use. The elastic element 42 can be made of a high-resilience material, automatically adjusting the clamping force according to the shape of the ear, ensuring stability without causing pressure. The second connector 43 is located inside the ear hook 30 and, in conjunction with the elastic element 42, further optimizes the fit of the earphone, ensuring comfort even during extended wear.

[0036] See Figures 4-9 The first connector 41 includes a first snap-fit ​​portion 411 and a first connecting portion 412 connected to each other. The first snap-fit ​​portion 411 may have a special geometric shape so that it fits into the receiving groove space of the first housing 20. A portion of the end face of the first snap-fit ​​portion 411 near the first connecting portion 412 abuts against the groove wall of the first receiving groove 21. After assembly, the snap-fit ​​portion forms multi-point contact with the inner wall of the receiving groove to achieve a firm connection between the first snap-fit ​​portion 411 and the first housing 20, avoiding loosening that may occur during use. The first connecting portion 412 serves as a transition component, with one end connected to the first snap-fit ​​portion 411 and the other end connected to the elastic member 42. In some embodiments, the elastic member 42 is stably connected to the first connecting portion 412, ensuring that the elastic member 42 maintains a stable connection during repeated deformation, preventing displacement or loosening. Simultaneously, the first connecting portion 412 may have adequate space for movement, ensuring that the elastic member 42 can freely expand and contract, achieving optimal elastic performance.

[0037] See Figures 4 to 10The ear hook 30 has a connecting groove 31 and a wire-passing groove 32 extending through both ends of the ear hook 30. The connecting groove 31 is used to house the elastic element 42 in the ear clip assembly 40, and the wire-passing groove 32 is used to house the wiring required by the wireless earphone 10. The connecting groove 31 and the wire-passing groove 32 are spaced apart. The reasonable spacing design ensures both structural strength and functional partitioning, effectively preventing the elastic element 42 from squeezing the wiring when it moves, and also avoiding the potential impact of electromagnetic signals from the wiring on the performance of the elastic element 42. The spaced area can be reinforced with ribs to reduce the overall weight while ensuring the structural rigidity of the ear hook 30. In some embodiments, the connecting groove 31 is a circular groove with a diameter of 1.6 mm. In some embodiments, the distance between the connecting groove 31 and the wire-passing groove 32 is 2 mm, which reduces interference between the elastic element 42 and the wiring without affecting the shape of the wireless earphone 10, and achieves functional partitioning within the ear hook 30. During the manufacturing and assembly process, one end of a flexible tube can be inserted into the second connector 43, and the other end can be fixed next to the first connector 41 so as to form a threading hole when the silicone outer shell is subsequently molded. After the ear hook 30 is molded, the spare flexible tube can be removed to obtain the required ear hook 30.

[0038] In some embodiments, the connecting groove 31 adopts an ergonomic arc design to match the trajectory of the elastic element 42, ensuring that the elastic element 42 can freely expand and contract without obstruction during deformation. The inner wall of the connecting groove 31 is specially polished, with a smooth and delicate surface, which can effectively reduce frictional resistance, allowing the elastic element 42 to move smoothly, thereby extending the service life of the wireless earphone 10. In some embodiments, the cross-sectional shape of the connecting groove 31 can be precisely calculated to provide sufficient space for the elastic element 42 to move while maintaining appropriate constraint force, ensuring that the elastic element 42 is always in the optimal working state. The wiring groove 32 serves as a wiring channel and is set parallel to the connecting groove 31 at a reasonable distance. The separate design of the wiring groove 32 and the connecting groove 31 effectively avoids mutual interference between the wiring and moving parts, ensuring the stability of signal transmission. Specifically, the inner wall of the wiring groove 32 can be made of wear-resistant material to provide comprehensive protection for the internal cables and prevent damage to the wiring due to long-term bending or friction. In some implementations, a guide structure may be designed at the entrance of the wiring trough 32 to facilitate wiring installation while preventing the wiring from becoming loose.

[0039] See Figures 4-7The second connector 43 includes an embedded portion 431 and a protruding portion 432 that are interconnected. The embedded portion 431 and the protruding portion 432 can be an integrated structure. A first step 433 is provided at the connection between the embedded portion 431 and the protruding portion 432. The first step 433 abuts against the end of the ear hook 30 away from the first connector 41 to fix the second connector 43. The protruding portion 432 can adopt a progressive transition design, extending naturally from the embedded portion 431. The first step 433 abuts against the end of the ear hook 30 away from the first connector 41. When the second connector 43 is installed in place, the first step 433 will form a stable limiting relationship with the internal structure of the ear hook 30, effectively preventing the second connector 43 from shifting or loosening during use, thus ensuring both the detachability of the component and the stability during use. In some embodiments, the contact surface of the first step 433 can adopt a micro-textured structure, which increases the friction between the first step 433 and the inner wall of the ear hook 30, avoiding the abnormal noise problem that may be caused by traditional buckle structures, while ensuring that a good fixing effect can still be maintained after long-term use. The edge of the step is rounded to prevent stress concentration and extend the service life of the wireless earphone 10. In some embodiments, a groove 33 is formed in the end of the ear hook 30 away from the first housing 20, and the insert 431 is engaged in the groove 33 to make the position of the second connector 43 relatively stable when the wireless earphone 10 is assembled.

[0040] In some embodiments, the first connector 41 and the second connector 43 are made of rigid plastic. Rigid plastic provides good mechanical properties, balancing structural strength and lightweight characteristics. The rigid plastic material of the first connector 41 and the second connector 43 exhibits excellent fatigue resistance, able to withstand repeated bending during daily use without easily deforming. Rigid plastic also has good environmental adaptability, resisting temperature changes and humidity fluctuations, maintaining stable performance over the long term. The rigid plastic material itself does not contain harmful substances, meeting human contact safety standards, and will not cause discomfort even after prolonged wear. Furthermore, the smooth surfaces of the rigid plastic first connector 41 and the second connector 43 provide a moderate coefficient of friction when mating with the internal structure of the ear hook 30, ensuring a smooth assembly experience and stable performance. The cross-sectional area of ​​the first connector 41 in the extension direction of the ear hook 30 is smaller than that of the second connector 43 in the same direction. The smaller cross-sectional area of ​​the first connector 41 ensures appropriate flexibility, allowing for natural adjustment to ear movements while avoiding additional burden on the wearer. The second connector 43 has a larger cross-sectional area, providing better support and ensuring the headphones remain stable in different usage scenarios. The larger contact area disperses the force, reducing localized pressure and improving wearing comfort. Specifically, in some embodiments, the cross-sectional area of ​​the first connector 41 in the ear hook 30 extension direction is half the cross-sectional area of ​​the second connector 43 in the ear hook 30 extension direction.

[0041] See Figures 2-7 The elastic element 42 is made of an alloy steel strip, which possesses good mechanical properties and durability. As the elastic element 42, the steel strip allows it to quickly return to its original shape after deformation, maintaining a stable clamping force. Through a professional heat treatment process, the microstructure of the steel strip is optimized, ensuring sufficient strength while maintaining just the right amount of flexibility, avoiding excessive hardness or softness. The elastic steel strip has a certain amount of room to move within the connecting groove 31, allowing it to adapt to the deformation requirements of the elastic element 42 caused by the user's head movements during wear.

[0042] In some embodiments, the end of the ear hook 30 furthest from the first housing 20 is connected to a second housing, and the second housing is connected to the ear hook 30. The first housing 20, the second housing, and the ear hook 30 can form an integral structure of the wireless earphone 10. A battery is housed in the second housing, which can be a high-performance lithium battery pack, ensuring sufficient power while maintaining the compact size and weight of the wireless earphone 10. A wire channel 32 passes through the second connector 43, and a lead wire is provided in the wire channel 32 to connect the battery and the speaker to form a complete signal transmission path. In some embodiments, the connection between the second housing and the ear hook 30 can be a snap-fit ​​structure, which is simple to assemble and easy to install.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
