Description

TECHNICAL FIELD

[0001] The present application relates to the earphone technical field, and in particular to an open earphone. BACKGROUND

[0002] With the vigorous development of the smart wear industry, the diversity of earphones is increasingly rich, and the differentiated needs of users for products are increasing. With the development of earphone products, the time that a single charge can be used is also getting longer and longer, and the demand of users for more convenient and comfortable long-time wearing of products is increasingly strong. The open earphone can be fixed to the ear through the form of ear clamping, can be worn for a long time, and does not enter the ear, which guarantees the perception of the environment and reduces the breeding of bacteria in the ear canal.

[0003] In the related art, due to the differences in ear shape and size of different people, the clamping force generated by the ear clamp structure of the open earphone cannot be adaptively adjusted, which will lead to unstable wearing and easy falling when worn loosely, and will lead to difficult operation and easy pain of the ear skin when wearing or removing the earphone when worn tightly, which greatly affects the user experience. CONTENT OF THE UTILITY MODEL

[0004] The embodiment of the present application provides an open earphone, which can significantly improve the comfort and stability of the open earphone wearing, and better adapt to different users.

[0005] The embodiment of the present application provides an open earphone, which comprises:

[0006] a first earphone body and a second earphone body;

[0007] a connecting bridge, one end of the connecting bridge being connected to the first earphone body; and

[0008] a rotating structure, the rotating structure comprising a first rotating member, a second rotating member and a reset member, the first rotating member and the second rotating member being rotationally connected, the first rotating member being connected to one end of the connecting bridge away from the first earphone body, the second rotating member being connected to the second earphone body, and the reset member connecting the first rotating member and the second rotating member, so that the second earphone body has a movement trend of approaching the first earphone body.

[0009] The open earphone based on the embodiment of the present application is connected with the first rotating part and the second rotating part through the reset part, so that the second earphone body has a movement trend of approaching the first earphone body when the open earphone is in the wearing state. Thus, when the ear size of the user is large, the rotating degree of the first rotating part and the second rotating part is relatively large, and the pulling force generated by the reset part is also increased correspondingly, so as to increase the clamping force on the ear. Conversely, when the ear size is small, the rotating degree of the first rotating part and the second rotating part is small, and the pulling force generated by the reset part is also decreased correspondingly, so as to avoid excessive clamping on the ear. Thus, the clamping force can be automatically adjusted according to the size of the ear of the user, the problem of ear pain caused by excessive local clamping force is effectively avoided, and the phenomenon of unstable wearing caused by insufficient clamping force is also solved. Therefore, the open earphone can significantly improve the comfort and stability of wearing, and better adapt to the actual needs of different users. BRIEF DESCRIPTION OF DRAWINGS

The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0027] With the vigorous development of the smart wear industry, the diversity of earphones is becoming more and more rich, and the user's differentiated demand for products is increasing. With the development of earphone products, the time that a single charge can be used is getting longer and longer, and the user's demand for more convenient and comfortable long-time wearing of the product is becoming more and more intense. The open earphone can be fixed to the ear by the form of ear clip, can be worn for a long time, and does not enter the ear, which guarantees the perception of the environment and reduces the breeding of bacteria in the ear canal.

[0028] In the related art, due to the difference in ear shape and size of different people, the clamping force generated by the ear clip structure of the open earphone cannot be adaptively adjusted, which will cause unstable wearing and easy falling when worn loosely, and will cause difficulty in operation and pain to the ear skin when the earphone is worn or removed when worn tightly, which greatly affects the user experience.

[0029] To solve the above problems, please refer to Figures 1 to 3 The present application proposes an open earphone 100. It can be understood that the open earphone 100 is usually provided with two, and the two open earphones 100 are symmetrically arranged. The two open earphones 100 can be worn on the left and right ears of the user, and the open earphone 100 should at least have a wearing state, which is a state in which the open earphone 100 cooperates with the user's ear to be relatively fixed, so that the user can obtain a more ideal listening effect.

[0030] In the embodiment of the present application, the open earphone 100 includes a first earphone body 10, a second earphone body 20, a connecting bridge 30 and a rotating structure 40.

[0031] The connecting bridge 30 is substantially in the shape of "U" or "C", one end of the connecting bridge 30 is connected to the first earphone body 10, the rotating structure 40 comprises a first rotating member 41, a second rotating member 42 and a reset member 43, the first rotating member 41 and the second rotating member 42 are rotatably connected, the first rotating member 41 is connected to the end of the connecting bridge 30 away from the first earphone body 10, the second rotating member 42 is connected to the second earphone body 20, and the reset member 43 is connected to the first rotating member 41 and the second rotating member 42, so as to make the second earphone body 20 have a movement tendency of approaching the first earphone body 10. When worn in this way, one of the first earphone body 10 and the second earphone body 20 is located on the front side of the ear, and the other is located on the back side of the ear. In this way, the first earphone body 10 and the second earphone body 20 are clamped and fixed on the front and back sides of the ear respectively. It should be noted that the rotating structure 40 can be completely embedded in the inside of the connecting bridge 30 or the second earphone body 20, achieving a concealed and seamless integration effect. Such design is generally aimed at maintaining the overall aesthetics and streamline appearance of the earphone, while ensuring that the rotating structure 40 works normally without affecting the appearance. On the other hand, the rotating structure 40 can also be exposed outside the connecting bridge 30 or the second earphone body 20. This design may pay more attention to functionality or operational convenience, so that the user can directly see or touch the rotating structure 40, which is convenient for some operations or adjustments.

[0032] In addition, the reset member 43 can be in the form of a torsion spring, a spring, etc. Due to the arrangement of the reset member 43, it not only serves as a medium for connection and fixation, but also adds the function of automatic reset to the entire rotating structure 40. When not subjected to external force, the natural state of the reset member 43 prompts the first rotating member 41 and the second rotating member 42 to remain in the initial fixed position, ensuring the stability and balance of the structure. When the user wears the open earphone, the first earphone body or the second earphone body needs to be first actuated for clamping, and when the external force is removed after wearing, the reset member 43 plays its reset role, so that the second earphone body 20 has a movement tendency of approaching the first earphone body 10.

[0033] Based on the open earphone 100 of the embodiment of the present application, the first rotating part 41 and the second rotating part 42 are connected through the reset part 43, so that when the open earphone 100 is in the wearing state, the second earphone body 20 has a movement trend of moving close to the first earphone body 10. Thus, when the size of the user's ear is large, the rotating degree of the first rotating part 41 and the second rotating part 42 is relatively large, and the pulling force generated by the reset part 43 is also increased accordingly, thereby increasing the clamping force on the ear. Conversely, when the size of the ear is small, the rotating degree of the first rotating part 41 and the second rotating part 42 is small, and the pulling force generated by the reset part 43 is also decreased accordingly, thereby avoiding excessive clamping of the ear. Thus, the clamping force can be automatically adjusted according to the size of the user's ear, effectively avoiding the problem of ear pain caused by excessive local clamping force, and also solving the problem of unstable wearing caused by insufficient clamping force. Therefore, the open earphone 100 can significantly improve the comfort and stability of wearing, and better adapt to the actual needs of different users.

[0034] With reference to Figures 3 to 5 In some structural forms, the second rotating part 42 includes a connecting part 421, a first fixed part 422 and a second fixed part 423, the first fixed part 422 and the second fixed part 423 are connected to the same side of the connecting part 421 and are arranged at intervals, and the connecting part 421 is fixed to the second earphone body 20. The first rotating part 41 is located between the first fixed part 422 and the second fixed part 423, one end of the first rotating part 41 is rotationally connected to the first fixed part 422, and the other end is limited and matched with the second fixed part 423 through the reset part 43.

[0035] Among them, the connecting part 421, the first fixed part 422 and the second fixed part 423 can be an integral structure, so as to ensure the strength of the overall structure of the second rotating part 42. Of course, the three can also be separately arranged, and can be installed and disassembled through screws or buckles, so as to facilitate later individual repair and replacement. The first rotating part 41 is rotationally connected with the first fixed part 422, and this connection allows the first rotating part 41 to rotate within a specific range. The first rotating part 41 is not directly connected with the second fixed part 423, but is limited and matched with the second fixed part 423 through the reset part 43. The reset part 43 is installed between the first rotating part 41 and the second fixed part 423. It is worth noting that the installation position of the reset part 43 is separate from the rotation connection position, which avoids interference during rotation and ensures smooth rotation and structural stability.

[0036] With reference to Figures 5 to 7Further, the first fixing part 422 is provided with a first mounting through hole 4221 along the axial direction thereof, and the hole wall of the first mounting through hole 4221 is provided with a limiting protrusion 4222. The reset member 43 comprises a reset main body 433 and a first supporting arm 431 and a second supporting arm 432 connected to the reset main body 433, the reset main body 433 is located in the first mounting through hole 4221, the first supporting arm 431 is in abutment with the limiting protrusion 4222, and the first rotating member 41 is provided with a limiting hole 4122 on the surface facing the first mounting through hole 4221, and the second supporting arm 432 passes through the limiting hole 4122 to be fixedly connected with the first rotating member 41.

[0037] The first mounting through hole 4221 can be a circular hole or a square hole. When the reset member 43 is a torsion spring, the first supporting arm 431 and the second supporting arm 432 are respectively rod-shaped bodies at opposite ends of the torsion spring. The limiting protrusion 4222 can be a block-shaped body with a limiting groove, so that the first supporting arm 431 can be embedded in the limiting groove to be limited. The surface of the first rotating member 41 opposite to the first mounting through hole 4221 is provided with a limiting hole 4122, so that the second supporting arm 432 passes through the first mounting through hole 4221 and is inserted into the limiting hole 4122 to realize the rotary connection of the first rotating member 41 and the first fixing part 422.

[0038] In combination with reference to Figure 5 , Figure 6 and Figure 8 , in some structural forms, the first rotating member 41 comprises a rotating shaft 411 and a rotating main body 412, the rotating shaft 411 is fixedly connected to the rotating main body 412, and one end of the rotating main body 412 away from the rotating shaft 411 is connected with the reset member 43. The second fixing part 423 is provided with a second mounting through hole 4231 along the axial direction thereof, the rotating shaft 411 passes through the second mounting through hole 4231 and rotates in the second mounting through hole 4231, and the second mounting through hole 4231 has two limiting stop walls 4232 on the rotating path of the rotating shaft 411, and the two limiting stop walls 4232 are used to abut against the rotating shaft 411.

[0039] The rotating shaft 411 and the rotating main body 412 can be an integral structure or can be separately arranged and connected through insertion or clamping. The second mounting hole 4231 has two limiting walls 4232, which are located on the rotating path of the rotating shaft 411. One limiting wall 4232 abuts against the rotating shaft 411 in the first rotating direction, and the other limiting wall 4232 abuts against the rotating shaft 411 in the second rotating direction. The limiting walls 4232 ensure that the rotating shaft 411 does not exceed the predetermined range during rotation, thereby synchronously limiting the rotating angle between the second rotating member 42 and the first rotating member 41. This improves the overall reliability of the rotating structure 40 and effectively avoids potential damage to the structure caused by excessive rotation, thereby prolonging the service life of the rotating structure 40. It should be noted that the rotating shaft 411 can be a pin, rivet, or the like.

[0040] Further, the two limiting walls 4232 are arranged at an angle, and the angle of the two limiting walls 4232 is not less than 30° and not greater than 90°. The angle of the two limiting walls 4232 can be 30°, 50°, 70°, etc. This limits the rotating angle of the rotating shaft 411 to effectively avoid excessive deviation or loss of control during rotation. By reasonably setting the angle, the rotating shaft 411 can rotate smoothly within the predetermined path without exceeding the allowed range or being damaged by excessive resistance. This design improves the overall reliability of the rotating structure 40 and prolongs its service life.

[0041] Referring to Figure 5 and Figure 6Optionally, the rotating shaft 411 comprises a fixed part 4111 and a rotating part 4112 connected together, the rotating body 412 is provided with a fixed through hole 4121 along its axial direction, the fixed part 4111 is inserted into the fixed through hole 4121, and the rotating part 4112 is arranged in the second mounting through hole 4231 and rotates in the second mounting through hole 4231. The fixed part 4111 and the rotating part 4112 are integrated to ensure the structural strength of the rotating shaft 411. When the fixed part 4111 is inserted into the fixed through hole 4121, the close fit between the two not only realizes stable mechanical connection, but also ensures the axial stability of the rotating shaft 411 during rotation. The cross-sectional area of the rotating part 4112 of the rotating shaft 411 is specially designed to be larger than that of the fixed part 4111. Such a larger cross-sectional area means stronger structural strength, which enables the rotating part 4112 to better withstand the friction and pressure from the inner wall of the second mounting through hole 4231 during rotation, thereby prolonging the service life of the rotating shaft 411; secondly, the larger size of the rotating part 4112 also provides more stable support for its rotation in the second mounting through hole 4231, reducing the shaking and noise caused by rotation. In addition, the fixed part 4111 is also specially designed with weight-reducing holes 411A, which effectively reduce the weight of the rotating shaft 411 while ensuring the structural strength.

[0042] With reference to Figure 5 and Figure 6 Optionally, the rotating body 412 is provided with a wire passing channel 41A passing through both surfaces. The open earphone 100 further comprises a flexible circuit board 50, one end of the flexible circuit board 50 is arranged in the first earphone body 10 through the connecting bridge 30, and the other end of the flexible circuit board 50 is arranged in the second earphone body 20 through the wire passing channel 41A. The main purpose of the above design is to realize the electrical connection between the electronic components in the first earphone body 10 and the second earphone body 20, and to ensure that the control signal can be accurately transmitted. By providing the wire passing channel 41A on the rotating body 412, not only is the connection path optimized, but also the wiring process is simplified, avoiding the messy situation of the cable, and effectively avoiding the exposure of the flexible circuit board 50. Such a design not only improves the stability and efficiency of signal transmission, but also enhances the overall aesthetics of the earphone. More importantly, due to the flexibility of the flexible circuit board 50, it can maintain good connection state even if the earphone deforms or moves during use, thereby ensuring the continuous and stable transmission of sound signals and providing users with a better auditory experience.

[0043] In some structural forms, with reference to Figure 5 and Figure 6The connecting portion 421 has two limiting protrusions 4211 extending away from the first fixing portion 422, which are spaced apart and inclined in opposite directions. The second earphone body 20 is provided with a groove 2111, and the two limiting protrusions 4211 are embedded in the groove 2111. The two limiting protrusions 4211 are not parallel or perpendicular, but inclined in opposite directions. This design not only increases the stability of the structure, but also plays a guiding and positioning role during assembly. At the same time, the second earphone body 20 is provided with a specially designed groove 2111, which is matched in shape and size with the two limiting protrusions 4211 on the connecting portion 421. When the connecting portion 421 is assembled with the second earphone body 20, the two limiting protrusions 4211 will be accurately embedded in the groove 2111, thereby achieving stable connection. This design not only ensures the close fit between the connecting portion 421 and the second earphone body 20, but also effectively prevents the connecting portion 421 from loosening or falling off during use of the earphone, improving the overall durability and stability of the earphone.

[0044] Referring to Figure 3 and Figure 9 Optionally, the second earphone body 20 includes a second housing 21 and an electric control assembly 22 and an antenna body 23 arranged in the second housing 21, and the antenna body 23 is electrically connected with the electric control assembly 22. The rotating structure 40 further includes an electric connecting piece 45, and the first rotating piece 41 and the second rotating piece 42 are made of metal material, and the electric connecting piece 45 is electrically connected with the electric control assembly 22, so that the rotating structure 40 and the antenna body 23 form an antenna structure.

[0045] The first rotating piece 41 and the second rotating piece 42 are made of metal material, which not only enhances the firmness of the structure, but also facilitates electrical connection. The electric connecting piece 45 can be a conductive element such as a wire or a spring, and the electric control assembly 22 can include a power supply 221 and a control circuit board 222, etc. The power supply 221 provides power for the speaker unit 12 and the control circuit board 222, and the electric connecting piece 45 is connected with the control circuit board 222 and also connected with the rotating structure 40, so that part of the rotating structure 40 serves as an antenna extension, together with the antenna body 23 to form an antenna structure. This design essentially expands the effective radiation area of the antenna, because the rotating structure 40 physically becomes part of the antenna. When the earphone is in use, whether the wearer's head rotates or the earphone moves slightly, the rotating structure 40 will change its form accordingly, but its metal material and electrical connection with the antenna body 23 ensure the stability and continuity of the antenna structure. This physical change directly leads to the improvement of the antenna radiation performance, making the earphone have higher sensitivity and efficiency in signal reception and transmission.

[0046] Further, if the rotating structure 40 is made of metal material as a whole, the rotating structure 40 can be used as an antenna extension, further increasing the effective radiation area of the antenna, and further improving the wireless communication performance of the earphone.

[0047] Referring to Figure 3 In some structural forms, the first earphone body 10 includes a first shell 11 and a speaker unit 12 arranged in the first shell 11, the first shell 11 is connected with the connecting bridge 30, the first shell 11 has a sound outlet hole 111, the speaker unit 12 divides the space of the first shell 11 into a front cavity 11A and a rear cavity 11B, and the front cavity 11A is communicated with the sound outlet hole 111. The connecting bridge 30 is provided with a sound guide channel 30A, one end of the sound guide channel 30A is communicated with the rear cavity 11B, and the other end of the sound guide channel 30A is communicated with the outside.

[0048] In this way, in the wearing state, the first earphone body 10 is used to be close to the ear canal of the wearer, so that the sound emitted from the sound hole 111 is easily heard by the wearer, and the second earphone body 20 is located at the rear side of the ear. The sound hole 111 of the first shell 11 serves as a window for sound output, which can be a round, square or strip shape. The speaker unit 12 is used to convert the received electrical signal into audible sound waves, which includes but is not limited to moving coil speaker, moving iron speaker, Mems speaker, vibrator, planar speaker and other electro-acoustic conversion devices. By forming a sound guide channel 30A in the connecting bridge 30 to communicate with the rear cavity 11B, the total volume and length of the rear cavity 11B are directly increased, and this physical space expansion has a significant impact on the propagation and resonance characteristics of the sound. Specifically, in acoustic theory, the volume and shape of the cavity have a decisive effect on the reflection, refraction and resonance frequency of the sound. The increase in the volume of the rear cavity 11B means that the distance of the sound wave propagating in it is increased, thereby providing more opportunities for the sound wave to interact with the cavity wall, resulting in more harmonic components. The superposition of these harmonic components helps to improve the fullness and layering of the sound, especially in the low frequency band, the longer propagation path and larger resonance space enable the low frequency sound wave to be better amplified and maintained, reducing the attenuation of low frequency energy, thus significantly improving the low frequency sound quality. In addition, the communication design of the sound guide channel 30A and the rear cavity 11B also promotes the flow and distribution of sound waves, making the propagation of sound waves between the inside and outside of the speaker unit 12 more smooth, reducing the obstruction and loss of sound waves in the propagation process. This smooth sound wave propagation path not only helps to improve the clarity and transparency of the sound, but also enables the sound to be more evenly distributed in space, providing a more immersive auditory experience for the wearer. The sound guide channel 30A as an important part of this system, its existence is not only to balance the internal and external air pressure, but also to fine-tune the low frequency response, reduce the back pressure effect, and improve the acoustic environment around the speaker unit 12. Specifically, the sound guide channel 30A maintains moderate communication with the outside air, which plays a key role when the speaker unit 12 is working, effectively balancing the internal air pressure changes caused by sound wave vibration, ensuring the stable operation of the speaker unit 12.

[0049] Further, the connecting bridge 30 comprises a bridge body 31 and a cover plate 32, which are connected to enclose the sound guide channel 30A. The bridge body 31 and the cover plate 32 are connected by precise covering and tightly cooperate to enclose the sound guide channel 30A. This enclosing process can use traditional screw fastening to ensure firm and durable connection, or can choose convenient buckle design to realize quick assembly and disassembly, improve operation efficiency and flexibility. At the same time, when the components in the sound guide channel 30A need to be maintained or replaced, the cover plate 32 can be easily opened by simply loosening the screws or unlocking the buckle, and the target components can be directly contacted, which greatly simplifies the maintenance process and reduces the maintenance cost. It should be noted that in other embodiments, the sound guide channel can also be formed in one of the bridge body 31 and the cover plate 32, and the space formed by covering the bridge body 31 and the cover plate 32 is used to install components such as microphones.

[0050] Optionally, the connecting bridge 30 is made of hard rubber material. The connecting bridge 30 is an important part of the earphone design that connects two earphone bodies, and needs to have sufficient structural strength to maintain the overall stability of the earphone, and also needs to provide a comfortable touch when worn. Hard rubber material generally has high hardness and toughness, which can effectively resist the impact and extrusion of external force, and ensure that the connecting bridge 30 is not easily deformed or damaged during use. At the same time, the hard rubber material also has a certain elasticity, which can provide moderate cushioning when worn, reduce the feeling of oppression of the earphone on the wearer's head, and improve the wearing comfort.

[0051] Referring to Figure 3 Further, the open earphone 100 further comprises a first microphone 60 and a second microphone 70, the first microphone 60 is arranged in the front cavity 11A, the first shell 11 is provided with a first microphone hole 112 communicating with the front cavity 11A, and the first microphone 60 is arranged corresponding to the first microphone hole 112. The connecting bridge 30 is provided with a second microphone hole 30a communicating with the sound guide channel 30A, and the second microphone 70 is arranged in the sound guide channel 30A and corresponding to the second microphone hole 30a.

[0052] The connecting bridge 30 is provided with a second microphone hole 30a communicating with a sound guide channel 30A, and the second microphone 70 is arranged in the sound guide channel 30A and corresponds to the second microphone hole 30a. In this way, the first microphone 60 and the second microphone 70 are integrated to enhance the audio acquisition and processing capability. The design of the microphone array not only expands the sound acquisition range of the earphone, but also improves the accuracy of sound acquisition. When the earphone is working, the first microphone 60 focuses on the acquisition of the sound in the ear canal, and the second microphone 70 is responsible for picking up the sound of the external environment. The two work together to provide rich and comprehensive sound materials for subsequent audio processing. Further, through the built-in noise reduction algorithm, the earphone can use the sound information collected by the two microphones to realize the functions of active noise reduction and environmental noise reduction. The ANC function can create a more quiet listening environment for the user by generating sound waves with opposite phase to the noise in the ear canal; and the ENC function can effectively reduce the interference of external noise during the process of calling or recording, and ensure the clarity and purity of sound transmission. It should be noted that the number of the first microphone 60 and the second microphone 70 can be multiple to further improve the sound pickup effect. The first microphone 60 and the second microphone 70 can be dynamic microphones, condenser microphones, MEMS microphones, etc.

[0053] Further, the open earphone 100 further comprises a bone conduction microphone 80, which is arranged in the rear cavity 11B and located near one side of the second earphone body 20. It can be understood that, when worn, the bone conduction microphone 80 captures the sound signals transmitted by the user's head bone vibration, rather than directly through air conduction. This feature makes it more effective in filtering out background noise during the call, significantly improving the clarity and quality of the call. At the same time, it also ensures that the bone conduction microphone 80 can stably and comfortably contact the user's ear, further enhancing its noise reduction effect.
