[0064] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0065] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "far", "near", "front", "back" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0066] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] The inventor found that in the prior art, by setting a detachable ear hook component, although the ear hook component can be matched with the user's auricle, it will bring many inconveniences: 1. The earphones need to be disassembled and assembled for adjustment, which is cumbersome; 2. Space is required to store other ear hook components, which is inconvenient to store and easy to lose; 3. This method does not solve the problem of the position of the speaker and the ear hole being offset, causing sound leakage and affecting the sound quality. The above shortcomings bring poor user experience to users when using headphones, and cannot guarantee the sound quality effect.

[0068] In order to solve the above problems, the inventors have proposed a retractable and rotatable ear hook assembly and earphones through research and development to better improve the user's wearing experience and sound quality.

[0069] Embodiment 1

[0070] The embodiment of the present application provides a retractable and rotatable ear hook assembly, which can be connected to an earphone assembly to form a Figure 1 The earphone shown in the figure, the ear hook assembly 13 is generally designed to be Figure 1 The hook shape shown in the figure can be hung on the user's auricle more stably, reducing the risk of the earphone falling off and improving the reliability of wearing. When the ear hook component 13 is hung on the user's auricle, the speaker of the earphone component 27 can be aligned with the user's ear hole to transmit and play audio.

[0071] See also Figure 2-Figure 4, the ear hook assembly 13 includes an ear hook body 22 and a rotating shaft assembly. The rotating shaft assembly includes a connecting shaft 21, a telescopic bracket 18, a torsion spring 15, a first connecting seat 16 and a second connecting seat 14. The telescopic bracket 18 is connected to the first end of the ear hook body 22, and the connecting shaft 21 is nested in the telescopic bracket 18, and can slide along the connecting shaft 21, and can drive the connecting shaft 21 to rotate. One end of the connecting shaft 21 extends to the outside of the telescopic bracket 18 and is connected to the first connecting seat 16. The second connecting seat 14 can be connected to the earphone assembly 27. The torsion spring 15 is connected between the first connecting seat 16 and the second connecting seat 14.

[0072] When in use, the user wears the ear hook assembly 13 on the auricle. At this time, the speaker of the earphone assembly 27 may deviate from the position of the ear hole. The user can pull the ear hook body 22, and the ear hook body 22 drives the telescopic bracket 18 to slide along the connecting shaft 21 to a suitable position, so as to achieve the purpose of telescoping the ear hook body 22. At the same time, the ear hook body 22 is rotated, and the ear hook body 22 drives the telescopic bracket 18 to rotate, and the telescopic bracket 18 drives the connecting shaft 21 to rotate, and the connecting shaft 21 drives the first connecting seat 16 to rotate, and the torsion spring 15 twists. Since the second connecting seat 14 is connected to the earphone assembly 27, the twisting of the torsion spring 15 makes the earphone assembly 27 and the ear hook body 22 have a certain angle, so that the speaker 7 of the earphone assembly 27 can be aligned with the position of the ear hole. The torsion spring 15 can provide a certain resistance and resilience when the user rotates the ear hook body 22, ensuring that the earphone can remain stable after being adjusted to a suitable position, and the angle is not easily changed due to external force.

[0073] In this embodiment, the user can adjust the fit between the ear hook body and the ear by stretching or shortening the telescopic bracket according to the size and shape of the ear, which can ensure that the ear hook body fits the auricle tightly, reduce slipping or discomfort caused by looseness, and improve wearing stability. There is no need to carry multiple ear hook components with you, and there is no need for complicated disassembly and assembly processes. Users can easily adjust the headphones according to their needs to achieve a personalized wearing experience. At the same time, by adaptively rotating the ear hook body, the user can adjust the angle between the speaker of the headphone assembly and the ear hole, so that the speaker of the headphone assembly can be aligned with the position of the ear hole, ensuring that the sound is transmitted directly and efficiently to the ear canal, reducing sound leakage. Through the above-mentioned telescopic and rotation functions, the purpose of improving the user's wearing comfort and sound quality is achieved in a coordinated manner, which greatly increases the user's convenience.

[0074] In a specific embodiment, see Figure 2 and Figure 4The connecting shaft 21 includes a limit plate (not shown in the figure) and a rotating shaft (not shown in the figure). The rotating shaft is arranged perpendicular to the limit plate and connected to the limit plate. The limit plate and the rotating shaft can be integrally formed, which not only simplifies the manufacturing process but also greatly improves the stability of the connection. The telescopic bracket 18 is a hollow sleeve and has a through hole (not shown in the figure) for one end of the rotating shaft to pass through. The aperture of the through hole is smaller than the outer edge diameter of the limit plate. The telescopic bracket 18 can slide along the rotating shaft to Figure 4 The right side wall of the telescopic bracket 18 shown in the figure abuts against the limit plate, which can effectively prevent the telescopic bracket 18 from sliding excessively. The cross-section of the shaft is non-circular, and the cross-section of the through hole matches the cross-section of the shaft, so that when the telescopic bracket 18 rotates, it can fit the shaft tightly and drive the shaft to rotate synchronously, thereby improving the accuracy and stability of the rotation. At the same time, due to the high degree of shape matching, the friction and wear during the rotation process are also reduced, and the durability is improved. Here, the non-circular shape can be a rounded rectangle, a triangle, a rectangle, a polygon or other special shapes.

[0075] In a specific embodiment, see Figure 2 and Figure 4 The shaft assembly also includes a damping silicone plug 20 and a positioning gasket 19. The damping silicone plug 20 is sleeved on the shaft and abuts against the limiting plate. The outer peripheral side of the damping silicone plug 20 abuts against the inner wall of the telescopic bracket 18 and forms an interference fit. The positioning gasket 19 is sleeved on the shaft and connected to the shaft, which is used to limit the damping silicone plug 20, which can prevent the damping silicone plug 20 from shifting or falling off during the sliding process of the telescopic bracket 18, thereby ensuring the stability and reliability of the entire shaft assembly. The damping silicone plug 20 can provide a certain damping feeling when the telescopic bracket 18 slides, making the sliding process more stable and controllable, and preventing the telescopic bracket 18 from sliding too fast or out of control; at the same time, because the damping silicone plug 20 can provide a certain resistance, the telescopic bracket 18 can maintain a stable state when it slides to the appropriate position, preventing misoperation and sliding looseness, thereby ensuring that the ear hook body 22 can be accurately adjusted to the most comfortable and appropriate wearing position.

[0076] In a specific embodiment, see Figure 5, the first connecting seat 16 is provided with a sliding groove 161, and the rotating shaft assembly also includes a rotation angle control seat 17. The first end of the rotation angle control seat 17 is provided with a rotating protrusion 171, and the rotating protrusion 171 can rotate in the sliding groove 161. The second end of the rotation angle control seat 17 is connected to the second connecting seat 14. When the ear hook body 22 drives the telescopic bracket 18 and the connecting shaft 21 to rotate, the rotating protrusion 171 will slide in the sliding groove 161, thereby limiting the rotation angle of the first connecting seat 16, thereby controlling the rotation angle of the entire ear hook assembly 13 and the earphone assembly 27 to achieve the best wearing effect and sound quality experience. The rotation angle control seat 17 not only controls the rotation angle, but also enhances the stability of the entire rotating shaft assembly through its structure. It ensures that the relative positions between the various components remain stable during the rotation process, reducing the noise and discomfort caused by looseness or misalignment.

[0077] It is worth noting that see Figure 2 The inner cavity of the earphone body 22 is provided with a connecting wire 29, which runs through the various components included in the above-mentioned shaft assembly. There is a suitable spacing between each component and the connecting wire 29, so that each component and the connecting wire 29 are independent of each other. When the shaft assembly rotates, the connecting wire 29 remains relatively still and does not rotate with the shaft assembly, which can avoid the connecting wire 29 from being twisted and damaged, thereby extending the service life of the earphone. At the same time, the length of the connecting wire 29 has a certain degree of redundancy. When the shaft assembly is extended or retracted, the connecting wire 29 will not be subjected to excessive pulling or tension, thereby avoiding damage to the connecting wire 29.

[0078] In a specific embodiment, see Figure 2-Figure 7 The ear hook assembly 13 also includes a battery assembly connected to the ear hook body 22, and the battery assembly includes a battery cover 23 and a battery 24, a charging copper column bracket 25 and a charging copper column FPC26 contained in the battery cover 23. The battery 24 is electrically connected to the earphone assembly 27 to provide power for the functional components (such as speakers, microphones, Bluetooth modules, etc.) in the earphone assembly 27. The battery cover 23 is connected to the second end of the ear hook body 22. The battery cover 23 is not only used to protect the battery 24, but also serves as a connecting component between the battery assembly and the ear hook body 22; a charging hole is provided on the outer wall of the battery cover 23 for access to an external charging device. The charging copper column FPC26 is limited in the battery cover 23 by the charging copper column bracket 25, and the charging copper column bracket 25 can ensure that the position of the charging copper column FPC26 in the battery cover 23 is stable; the charging port of the charging copper column FPC26 is contained in the charging hole, which is convenient for users to perform charging operations. At the same time, the charging copper column FPC26 is electrically connected to the battery 24 to ensure that the charging current can be smoothly transmitted to the battery. The integrated design of the components of the battery assembly not only provides stable power support for the earphone assembly 27, but also cleverly integrates the charging function, making the entire earphone system more convenient and practical.

[0079] Embodiment 2

[0080] Based on the same inventive concept, see Figure 1 An embodiment of the present application proposes an earphone, which includes an earphone component 27 and the retractable and rotatable ear hook component 13 described in embodiment 1, wherein the second connecting seat 14 is connected to the earphone component 27.

[0081] In a specific embodiment, see Figure 1 and Figure 8 The earphone assembly 27 includes an earphone upper shell 1 and a connecting sleeve 28 provided on the outer side wall of the earphone upper shell 1. The connecting sleeve 28 is sleeved on the outer side of the telescopic bracket 18, the rotation angle control seat 17 and the second connecting seat 14, and the connecting sleeve 28 is connected to the rotation angle control seat 17. Here, the connection can be made by dispensing glue, and a clamping groove (not shown in the figure) is provided on the inner side wall of the connecting sleeve 28, and the second connecting seat 14 is provided with a clamping member (not shown in the figure), which is clamped in the clamping groove, so that the connecting sleeve 28 is firmly connected to the second connecting seat 14. This connection method is not only simple and reliable, but also can withstand certain tension and torsion, ensuring that the second connecting seat 14 will not be easily detached or loosened from the connecting sleeve 28 due to external force during use, so as to ensure the stability and reliability of the earphone during use.

[0082] Since the connecting sleeve 28 is sleeved on the outside of the telescopic bracket 18, the rotation angle control seat 17 and the second connecting seat 14, on the one hand, it achieves aesthetics and plays a protective role; on the other hand, when the ear hook body 22 is rotated in the manner of Example 1, the ear hook body 22 drives the telescopic bracket 18 to rotate, the telescopic bracket 18 drives the connecting shaft 21 to rotate, the connecting shaft 21 drives the first connecting seat 16 to rotate, and the torsion spring 15 twists, so that the earphone assembly 27 and the ear hook body 22 produce a certain angle, so that the speaker 7 of the earphone assembly 27 can be aligned with the position of the ear hole, providing the best wearing comfort and sound quality effect.

[0083] In a specific embodiment, see Figure 8 The earphone assembly 27 also includes a speaker front shell 10, which is connected to the earphone upper shell 1 to ensure that the sound can be accurately transmitted to the user's ears. The direction of the rebound force generated by the torsion spring 15 is the direction from the earphone upper shell 1 to the speaker front shell 10. For details, see Figure 1 and Figure 4 , Figure 1 The schematic diagram of the left earphone is given. For the left earphone, the torsion spring 15 is as follows Figure 4 As shown in the right-handed torsion spring, when the ear hook body 22 rotates and transmits the rotation to the torsion spring 15, the torsion spring 15 will rotate clockwise (to Figure 1 As a reference to determine the rotation direction), the rebound force generated by the torsion spring 15 is counterclockwise (with Figure 1 As a reference for determining the rotation direction), the earphone upper shell 1 is facing downward.

[0084] In this embodiment, when the ear hook body 22 is adjusted to a suitable position, the torsion spring 15 will exert an inward force to "press" the earphone assembly 27 toward the user's ear, so that the earphone assembly 27 can fit the user's ear better, and the earphone assembly 27 can more effectively transmit the sound to the ear canal, reducing the loss and reflection of the sound in the air, which not only improves the clarity of the sound, but also reduces the occurrence of sound leakage. Therefore, the user can feel a purer and fuller sound quality effect and obtain a more immersive listening experience.

[0085] In a specific embodiment, see Figure 8 The earphone assembly 27 also includes an earmuff 12 connected to the front speaker shell 10. The earmuff 12 can be made of sponge and protein earmuff 12, which is soft and comfortable. With the rebound force generated by the torsion spring 15, the earmuff 12 fits the user's ear, which not only improves the wearing stability, but also enables the sound to be more directly and efficiently transmitted to the user's ear canal, reducing the loss and reflection of the sound, thereby maintaining a good sound quality performance, and the soft earmuff 12 will not make the user feel uncomfortable, and can ensure the wearing comfort.

[0086] In a specific embodiment, see Figure 8 , the earphone assembly 27 also includes an antenna and touch FPC2, an earphone motherboard 4, a speaker cover 5, a speaker 7, and a FB microphone and a call microphone FPC9. The first end of the speaker cover 5 can be buckled with the speaker front shell 10 to ensure sealing and stability, and the second end of the speaker cover 5 is connected to the earphone motherboard 4 to achieve electrical connection and support the earphone motherboard 4. A accommodating space is formed between the speaker cover 5 and the speaker front shell 10, and the FB microphone and the call microphone FPC9 and the speaker 7 are arranged in the accommodating space and connected to the speaker front shell 10 to ensure accurate transmission and reception of sound signals. The antenna and touch FPC2 are arranged between the earphone motherboard 4 and the earphone upper shell 1, and are connected to the earphone upper shell 1, which can realize wireless communication between the earphone and an external device (such as a mobile phone, a computer, etc.), such as a Bluetooth connection, and the touch control function of the earphone, such as answering a call, adjusting the volume, etc., to ensure a good wireless communication and touch control experience. The earphone assembly 27 connects each component tightly together through a carefully designed structure to form an efficient and reliable sound system. The speaker cover 5, FB microphone and talk microphone FPC 9, speaker 7, headset mainboard 4, antenna and touch FPC 2 and other components work together to provide users with high-quality audio experience and convenient touch operation. This structural design not only ensures the sound quality and performance of the headset, but also improves the durability and comfort of the product.

[0087] In a specific embodiment, the earphone assembly 27 also includes a speaker 7 mesh, a rear cavity mesh 6, a call microphone mesh 83 and a noise reduction microphone mesh. The speaker 7 mesh is arranged between the speaker front shell 10 and the earmuff 12, and the speaker 7 mesh is connected to the speaker front shell 10. The speaker 7 mesh is connected to the speaker front shell 10, and the speaker 7 mesh can effectively prevent dust and foreign objects from entering, while ensuring that the sound can be transmitted smoothly. The rear cavity mesh 6 is connected to the speaker cover 5, and the design of the rear cavity mesh 6 can ensure air circulation while preventing dust and foreign objects from entering. The noise reduction microphone mesh is connected to the earphone mainboard 4, and the call microphone mesh 83 is connected to the FB microphone and the call microphone FPC9 to prevent dust, water vapor and foreign objects from entering.
