Description

Technical Field

[0001] The present application relates to the technical field of earphones, and in particular to an ear-clip earphone. Background Art

[0002] Open-back headphones are Bluetooth headphones that do not need to go deep into the ear canal, allowing users to maintain awareness of the surrounding environment while enjoying music or calls. Among open-back headphones, ear-hook and ear-clip are two common design forms. The ear-hook type fixes the headphones above the ears and is supported by a frame around the ears to provide stability and comfort; the ear-clip type headphones are fixed by clamping on the auricle.

[0003] At present, there are three main ways to realize the wearing of ear clip earphones: one is through elastic deformation of soft glue, the second is to achieve elastic deformation through the combination of memory metal and soft glue, and the third is through micro deformation of hard glue. The size and structure of human ears vary greatly. When the thickness of the human ear is larger than the ideal value of the ear clip design, the deformation variable is too large, resulting in a larger earphone clamping force, which reduces the wearing comfort. When the thickness of the human ear is smaller than the rational value of the design, the deformation variable is too small, resulting in a smaller earphone clamping force, which reduces the wearing stability. Whether it is soft glue or memory metal, the elastic modulus of the deformation of the whole machine is adjusted by the material, and the adjustment is very limited. The adaptability of wearing mainly depends on the internal ear clip structure of the earphone, and the human ear has different shapes. Therefore, the structural design of the existing ear clip earphones cannot well match the wearing needs of different groups of people. Utility Model Content

[0004] The embodiment of the present application provides an ear-clip type earphone, which can adjust the clamping force to better match the wearing needs of different groups of people.

[0005] An embodiment of the present application provides an ear-clip earphone including a sound-emitting component, an adjustment component and a connecting bridge component, wherein the connecting bridge component connects the sound-emitting component and the adjustment component; wherein the adjustment component includes a bracket and an adjustment member, the adjustment member is movably connected to the bracket, and a first magnet is arranged on the side facing the sound-emitting component, the sound-emitting component is provided with a second magnet opposite to the first magnet, and the adjustment member can drive the first magnet to move under the drive of an external force to adjust the magnitude of the magnetic attraction between the first magnet and the second magnet.

[0006] Based on the ear clip earphone of the embodiment of the present application, by providing the first magnet and the second magnet, there is magnetic attraction between the sound component and the adjustment component, so that the sound component and the adjustment component can stably fit the user's ear, provide a good clamping effect, and the ear clip earphone is firmly clamped on the ear. And by adjusting the magnitude of the magnetic attraction, the user can easily wear or remove the ear clip earphone on the ear, which can improve the convenience of use.

[0007] This embodiment is also provided with an adjusting member, which allows the user to actively adjust the magnetic attraction force between the first magnet and the second magnet according to the size and shape of the individual auricle. This adjustability enables the earphone to adapt to the ear sizes of different users, provides personalized adjustment for wearing, improves the adaptability to the ear shapes of different users, and enables the product to serve a wider range of user groups.

[0008] The user can adjust the adjusting member according to different usage scenarios (such as sports or sedentary office work) to meet the requirements for stability and comfort in different situations. For example, increasing the magnetic attraction force during sports to ensure that the earclip-type earphone will not fall off due to intense exercise, and reducing the magnetic attraction force during office work to improve the comfort of long-term wearing.

[0024] A wireless earphone is a device that transmits audio signals through radio waves, allowing users to use it without physical cables. Wireless earphones are divided into three parts: the first part is the sound source, the second part is the receiver, and the third part is the earphone part, whose main function is to convert the signals transmitted from the mobile phone or the receiver into sound and then transmit it to the human ear.

[0025] In recent years, ear-clip headphones, as a new form of wireless earphones, have gradually attracted market attention and popularity. The design of ear-clip headphones does not require inserting the earphones into the ear canal, but is fixed by clamping above the ear. This design not only reduces the discomfort during wearing but also improves the ventilation of the earphones, making it not feel stuffy or sweaty even after long-term wearing.

[0026] Ear-clip headphones usually have an open design, which means they do not completely seal the ear canal, thus allowing ambient sound to enter. This is a great advantage for users who need to pay attention to the surrounding ambient sound. In addition, the design of ear-clip headphones often pays more attention to comfort and stability, and many products use lightweight materials and ergonomic designs to ensure comfort during long-term wearing.

[0027] In related technologies, ear-clip headphones include a sound-emitting part, a battery part, and a connecting bridge part connecting the sound-emitting part and the battery part. A speaker is provided in the sound-emitting part, and the sound-emitting part is used to be worn in the concha of the human ear, while a battery is provided in the battery part to provide power for the speaker. A shape-memory metal piece is provided in the connecting bridge part, which can be bent and deformed and restored. However, although the shape-memory metal provides a certain degree of shaping ability, the sizes and shapes of different users' ears vary greatly, and a single shape-memory metal piece may not be able to meet the needs of all users, resulting in insufficient wearing stability or comfort of the earphones.

[0028] To solve the above problems, please refer to Figures 1 to 2, a first aspect of the present application proposes an earclip-type earphone 100. In an embodiment of the present application, the earclip-type earphone 100 includes a sound generating component 10, an adjusting component 20, and a connecting bridge component 30. The sound generating component 10 is configured to be worn in the concha cavity, and a speaker unit 13 is housed therein. The speaker unit 13 converts an electrical signal into a sound waveform and transmits it to the ear canal opening. The sound generating component 10 can provide good sound sealing and directivity, thereby enhancing the sound quality and reducing interference from external noise. The earclip-type earphone further includes a battery 40, which is used to provide power for the speaker unit 13 to ensure its continuous operation. Among them, the connecting bridge component 30 connects the sound generating component 10 and the adjusting component 20, and the connecting bridge component 30 can provide a connecting and supporting function.

[0029] Among them, the connecting bridge component 30 includes an outer sheath 31 and a shape memory metal part 32 embedded in the outer sheath 31 (such as Figure 5 ), both ends of the outer sheath 31 are respectively connected to the sound generating component 10 and the adjusting component 20. The material of the outer sheath 31 can be one of thermoplastic polyurethane elastomer (TPEE) material, thermoplastic elastomer (TPU) material, and silicone resin material, which has a certain softness, helps to improve the wearing comfort, and alleviates the problem of ear pain caused by squeezing the human ear for too long during wearing. The distance between the sound generating component 10 and the adjusting component 20 in the wearing state can be adjusted by bending the shape memory metal part 32. The shape memory metal part 32 is made of nickel-titanium alloy, which has good durability and fatigue resistance and can withstand multiple deformations without losing its recovery performance.

[0030] Furthermore, the adjusting component 20 includes a bracket 21 and an adjusting member 22. The adjusting member 22 is movably connected to the bracket 21. A first magnet 23 is provided at one end of the adjusting member 22 close to the sound generating component 10, and a second magnet 11 is provided on the sound generating component 10 opposite to the first magnet 23. The adjusting member 22 can drive the first magnet 23 to move under the drive of an external force to adjust the magnetic attraction force between the first magnet 23 and the second magnet 11.

[0031] By providing the first magnet 23 and the second magnet 11, a magnetic attraction force is generated between the sound generating component 10 and the adjusting component 20. The sound generating component 10 and the adjusting component 20 can stably fit the user's ear, providing a good clamping effect, so that the earclip-type earphone is firmly clamped on the ear. And by adjusting the magnitude of the magnetic attraction force, the clamping force of the earclip-type earphone 100 can be adjusted, facilitating the user to easily wear or remove the earclip-type earphone 100, thereby improving the convenience of use.

[0032] The adjusting member 22 provided in this embodiment allows the user to actively adjust the magnetic suction force between the first magnet 23 and the second magnet 11 according to the size and shape of the individual auricle. This adjustability enables the earphone to adapt to the ear sizes of different users, provides personalized adjustment for wearing, improves the adaptability to the ear shapes of different users, and enables the product to serve a wider user group.

[0033] The user can adjust the adjusting member 22 according to different usage scenarios (such as exercise or sedentary office work) to meet the requirements for stability and comfort in different situations. For example, increasing the magnetic suction force during exercise to ensure that the earclip earphone 100 does not fall off due to strenuous exercise, and reducing the magnetic suction force during office work to improve the comfort of long-term wearing.

[0034] In one setting form, the adjusting member 22 is slidably connected to the bracket 21, and the adjusting member 22 can drive the first magnet 23 to slide in a direction approaching or away from the second magnet 11 under the drive of an external force. Specifically, a sliding track is provided between the adjusting member 22 and the bracket 21, and the user can directly pull the adjusting member 22 to achieve the linear expansion and contraction of the adjusting member 22. A first magnet 23 is provided at one end of the adjusting member 22 close to the sound generating component 10, and a second magnet 11 is provided at the corresponding position of the sound generating component 10. The adjusting member 22 can drive the first magnet 23 to approach or away from the second magnet 11 under the drive of an external force, that is, when the user pulls the adjusting member 22, the adjusting member 22 drives the first magnet 23 to move along a preset track, thereby changing the distance between the first magnet 23 and the second magnet 11 to adjust the magnetic suction force between the first magnet 23 and the second magnet 11. In this way, the user can adjust the size of the magnetic suction force according to personal preference, and further adjust the fixation and comfort of the earclip earphone 100.

[0035] In another setting form, the adjusting member 22 can also be rotatably connected to the bracket 21, and the adjusting member 22 can drive the first magnet 23 to rotate under the drive of an external force to adjust the magnetic suction force between the first magnet 23 and the second magnet 11. As Figure 3As shown, the magnetic poles of the first magnet 23 and the second magnet 11 both have a bipolarity with opposite magnetic poles coexisting simultaneously, and are both radially magnetized. Moreover, the first magnet 23 is arranged opposite to the second magnet 11 along the axial direction of the second magnet 11, which can optimize the distribution of magnetic field lines, reduce the waste of the magnetic field, and improve the utilization efficiency of magnetic energy. In the initial state, the N pole of the second magnet 11 is correspondingly arranged with the S pole of the first magnet 23, that is, the S pole of the second magnet 11 is correspondingly arranged with the N pole of the first magnet 23. The corresponding magnetic poles (N pole and S pole) of the first magnet 23 and the second magnet 11 will attract each other, enhancing the magnetic attraction force between the two. This helps to maintain the stable connection between the sound generating component 10 and the adjusting component 20 during the use of the earphone, and it is not easy to cause position deviation due to external factors (such as vibration, movement). If the user feels it is too tight, the first magnet 23 can be rotated by rotating the adjusting member 22, which can change its relative polarity with the second magnet 11, thereby adjusting the magnitude of the magnetic attraction force between the two.

[0036] To generate the strongest magnetic field with the least amount of magnets, the first magnet 23 is configured as a Halbach array. The magnetic field intensity on the side of the first magnet 23 facing the second magnet 11 is greater than the magnetic field intensity on the side of the first magnet 23 facing away from the second magnet 11. This makes the side of the second magnet 11 facing the first magnet 23 have a stronger magnetic attraction force, thereby enhancing the clamping force and stability of the earphone. The enhanced magnetic attraction force helps to improve the stability of the earclip-type earphone 100 during various activities (including strenuous exercise) and reduces the possibility of the earclip-type earphone 100 falling off. The first magnet 23 is arranged on the adjusting component 20. When using less magnetic material for the first magnet 23 to achieve the required magnetic attraction force, it helps to reduce the weight of the adjusting component 20, reduce the pressure on the ear caused by the adjusting component 20, and provide a more comfortable wearing experience, especially suitable for users who use earphones for a long time.

[0037] In some setting forms, the second magnet 11 can be configured as a Halbach array. The magnetic field intensity on the side of the second magnet 11 facing the first magnet 23 is greater than the magnetic field intensity on the side of the second magnet 11 facing away from the first magnet 23. The second magnet 11 is arranged on the sound generating component 10. It can reduce the number or volume of magnets of the second magnet 11 without sacrificing the magnetic attraction force, which helps to reduce the size of the sound generating component 10 and achieve a more compact design of the sound generating component 10. Since the size of the concha of the human ear is limited, the smaller sound generating component 10 can be worn to fit the concha of the ear, making the size of the sound generating component 10 match the size of the user's concha of the ear.

[0038] In yet another setting form, both the second magnet 11 and the first magnet 23 are configured as Halbach arrays. The magnetic field intensity on the side of the second magnet 11 facing the first magnet 23 is greater than that on the side of the second magnet 11 facing away from the first magnet 23, and the magnetic field intensity on the side of the first magnet 23 facing the second magnet 11 is greater than that on the side of the first magnet 23 facing away from the second magnet 11. The interaction between the two Halbach arrays can generate a stronger magnetic suction force than a single array, complementing and enhancing each other to achieve a better magnetic field distribution, making the magnetic force more concentrated and effective, thereby significantly improving the clamping force and stability of the earclip-type headphones 100.

[0039] In another setting form, the second magnet 11 includes a plurality of first magnetic units, and the plurality of first magnetic units are arranged at intervals in a ring shape. Among them, the magnetic suction forces between adjacent two first magnetic units are different. The first magnet 23 includes at least two second magnetic units arranged evenly in a ring shape. When the first magnet 23 rotates relative to the second magnet 11, at least two of the second magnetic units can be aligned with at least two of the plurality of first magnetic units. Due to the difference in the magnetic suction forces between adjacent two first magnetic units, this causes the magnetic suction force generated during the rotation of the first magnet 23 relative to the second magnet 11 to also show different change situations. For example, at a certain moment, when two second magnetic units are aligned with two first magnetic units with stronger magnetic suction forces, the magnetic suction force generated at this time is larger; as the rotation continues, when these two second magnetic units are aligned with another two first magnetic units with weaker magnetic suction forces, the magnetic suction force will decrease accordingly, realizing the adjustment of the clamping force between the bracket 21 and the sound-emitting component 10.

[0040] In this setting form, the adjusting member 22 includes an adjusting housing and an elastic engaging member. The adjusting housing is connected to the first magnet 23 and is used to drive the first magnet 23 to rotate, and a continuously arranged groove is formed on its inner wall. The elastic engaging member can be positioned and engaged in the groove, and the central angle between adjacent two grooves is equal to the angle of alignment between the second magnetic unit and the first magnetic unit each time, realizing the rapid switching of different magnetic force requirements.

[0041] In another embodiment, as Figure 4 and Figure 5As shown, the bracket 21 is connected to the connecting bridge assembly 30, which can enhance the stability of the bracket 21 and prevent displacement of the bracket 21 caused by external forces. The adjusting member 22 includes an adjusting knob 221. The bracket 21 is rotatably nested with the adjusting knob 221. When the adjusting knob 221 rotates circumferentially, the bracket 21 can maintain its connection position with the connecting bridge assembly 30 without significant radial displacement, reducing the uncertainty during use. The first magnet 23 is fixed on the adjusting knob 221. The adjusting knob 221 provides an accurate adjustment method. The user rotates the adjusting knob 221 to finely adjust the rotation of the first magnet 23 relative to the second magnet 11 to achieve adjustment of the clamping force between the bracket 21 and the sound generating assembly 10. Among them, a receiving cavity 221a is formed in the adjusting knob 221. The battery 40 and the first magnet 23 are both received in the receiving cavity 221a. The bracket 21 may further include a printed circuit board 50. The printed circuit board 50 is electrically connected to the battery 40 and received in the receiving cavity 221a. The printed circuit board 50 includes a microcontroller or other control chips for controlling various functions of the earclip-type headset 100, such as volume adjustment, power on / off; arranged in a compact manner to save space and make the headset design more lightweight and portable. Understandably, the printed circuit board 50 can also be arranged in the sound generating assembly 10, and the present application does not limit this.

[0042] Further, an installation hole 21a is formed in the bracket 21. The adjusting knob 221 is rotatably installed in the installation hole 21a. The adjusting member 22 further includes a damping member 222. The damping member 222 is located between the adjusting knob 221 and the hole wall of the installation hole 21a. The damping member 222 can provide a damping force for the rotation of the adjusting knob 221. The damping force can slow down the movement speed of an object by absorbing and dissipating energy, enabling the object to stop or change position smoothly, providing a rotational feel for the user to achieve a smooth adjustment process. And the damping member 222 also has a sealing function, which can prevent dust, moisture and other tiny particles from entering the installation hole 21a, improving the durability and protection level of the earclip-type headset 100.

[0043] To limit the adjustment range, as Figure 6 shown, one of the bracket 21 and the adjusting knob 221 is provided with a first limiting portion, and the other of the two is provided with a second limiting portion. Among them, the first limiting portion is used to limit and abut against the second limiting portion during the rotation adjustment stroke of the adjusting knob 221. When the adjusting knob 221 rotates to the stop position, the user will receive a clear physical feedback, and the user can accurately control the adjustment position of the knob to prevent the rotation of the adjusting knob 221 from exceeding the design limit. In this embodiment, the rotation range of the adjusting knob 221 is between 0° and 180°.

[0044] Specifically, the bracket 21 is provided with a first limiting portion, and the adjusting knob 221 is provided with a second limiting portion, the first limiting portion is a limiting protrusion 211, and the second limiting portion is a limiting groove 2213; a limiting protrusion 211 is convexly provided on the inner wall of the mounting hole 21a, and a limiting groove 2213 adapted to the limiting protrusion 211 is provided on the wall surface of the adjusting knob 221, and the limiting protrusion 211 has a stop surface, and the groove wall of the limiting groove 2213 abuts against the stop surface, so that the bracket 21 limits the adjusting knob 221 in the circumferential direction of the mounting hole 21a.

[0045] In another structural form, a first limiting portion is protruding on the outer peripheral wall of the adjusting knob 221, and the first limiting portion extends to the outer peripheral wall of the bracket 21. A second limiting portion is protruding on the outer peripheral wall of the bracket 21. On the one hand, the first limiting portion can be used as an anti-slip protrusion when the user rotates the adjusting knob 221, thereby increasing the friction force of the rotating adjusting knob 221 and providing the user with a better grip point. When the first limiting portion of the adjusting knob 221 rotates to abut against the second limiting portion, the second limiting portion limits the rotation of the adjusting knob 221 in the circumferential direction of the mounting hole 21a, thereby preventing the adjusting knob 221 from excessive rotation.

[0046] Furthermore, if Figure 5 and Figure 7 As shown, the adjustment knob 221 includes a knob cap 2211 and a knob cover 2212, which are snap-fitted and cooperate to define a receiving cavity 221a, and the knob cover 2212 is arranged relative to the sound-emitting component 10. When worn, the knob cap 2211 is located on the side away from the human ear, so that the user can easily rotate the knob cap 2211 to synchronize the knob cover 2212. The first magnet 23 is located in the knob cover 2212, and the knob cover 2212 can provide protection for the first magnet 23 to prevent the first magnet 23 from being impacted by the outside world. The knob cap 2211 and the knob cover 2212 are respectively limited to opposite sides of the bracket 21 along the axial direction of the mounting hole 21a. The damping member 222 includes a first damping ring 2221 and a second damping ring 2222. The first damping ring 2221 is located between the knob cap 2211 and the hole wall of the mounting hole 21a, and the second damping ring 2222 is located between the knob cover 2212 and the hole wall of the mounting hole 21a, which can provide a mute effect for the relative rotation between the knob cap 2211 and the knob cover 2212 and the bracket 21. The knob cap 2211 and the knob cover 2212 are buckled to form an annular groove. The bracket 21 is embedded in the annular groove and forms a smooth outer peripheral surface with the outer walls of the knob cap 2211 and the knob cover 2212, thereby enhancing the overall aesthetics of the ear clip type earphone 100.

[0047] Among them, the knob cap 2211 includes an operation part 2211a and a rotation part 2211b connected to each other. The rotation part 2211b is rotatably inserted into the mounting hole 21a and is snap-connected to the knob cover 2212. The rotation part 2211b can rotate around the central axis of the mounting hole 21a. The operation part 2211a is exposed outside the mounting hole 21a to provide a grip for the user. Among them, the connection part between the operation part 2211a and the rotation part 2211b is provided with a step to form a step surface, and the step surface abuts against the periphery of the mounting hole 21a to improve the stability of the knob cap 2211 during rotation and reduce possible shaking or deviation.

[0048] In some embodiments of the present application, the sound generating assembly 10 further includes a sound generating housing 12. A speaker unit 13 is accommodated in the sound generating housing 12. The speaker unit 13 divides the space in the sound generating housing 12 into a front cavity 12a and a rear cavity 12b. The second magnet 11 is accommodated in the rear cavity 12b. The second magnet 11 is arranged in the rear cavity 12b and can be closer to the first magnet 23 arranged in the knob cover 2212, thereby improving the efficiency of magnetic suction. Among them, the sound generating housing 12 is provided with a tuning hole 121, and the tuning hole 121 communicates with the outside. The second magnet 11 is provided with a first through hole 11a communicating with the tuning hole 121. The tuning hole 121 can adjust the air flow, reduce internal resonance, and improve the sound quality.

[0049] Understandably, when the second magnet 11 is configured as a Halbach array, the magnetic field intensity on the side of the second magnet 11 facing the speaker unit 13 is weak, which can reduce the potential interference to the speaker unit 13 and reduce the negative impact on sound quality distortion or frequency response change.

[0050] The sound generating housing 12 includes an ear shell 123 and a face cover 124 that are snap-connected to each other. The outer surfaces of the ear shell 123 and the face cover 124 are smoothly connected to provide good sealing, reduce the interference of external noise, and improve the sound insulation effect of the sound generating components. The ear shell 123 and the speaker unit 13 enclose and define the above-mentioned front cavity 12a, and the face cover 124 and the speaker unit 13 enclose and define the above-mentioned rear cavity 12b. The above-mentioned tuning hole 121 is opened on the face cover 124. The second magnet 11 is arranged on the inner surface of the face cover 124. The sound generating assembly 10 further includes a mesh cloth 15. The mesh cloth 15 is located between the face cover 124 and the second magnet 11 and covers the tuning hole 121. The mesh cloth 15 can reduce the acoustic resistance to the speaker unit 13.

[0051] The side wall of the sound shell 12 is provided with sound holes 122 communicating with the front cavity 12a. Specifically, they are arranged on the ear shell 123. The ear shell 123 can cover the ear canal opening of the user's ear without extending into the ear canal, and the sound holes 122 are arranged in the direction towards the ear canal opening when the ear clip - type earphone 100 is in the wearing state. This improves the mid - frequency performance of the speaker unit 13, so that the speaker unit 13 can simultaneously meet the requirements of low - frequency, mid - frequency and high - frequency sound quality, providing a better sound quality experience for users.

[0052] The sound - generating assembly 10 further includes a dust - proof net 16. The dust - proof net 16 is located on the outer wall of the ear shell 123 and covers the sound holes 122. The dust - proof net 16 can isolate dust in the air from entering the sound holes 122, protecting the speaker unit 13 from the influence of dust accumulation.

[0053] Furthermore, the sound - generating assembly 10 further includes a shielding assembly 14. The shielding assembly 14 is arranged in the rear cavity 12b and is located between the second magnet 11 and the speaker unit 13. The shielding assembly 14 can effectively block the electromagnetic interference of the magnetic field that the second magnet 11 may generate on the speaker unit 13, ensuring the purity of the sound quality. The shielding assembly 14 is provided with a second through - hole 14a. The second through - hole 14a communicates with the rear cavity 12b. The second through - hole 14a on the shielding assembly 14 communicates with the first through - hole 11a on the second magnet 11, which can finely adjust the air flow in the rear cavity 12b, thereby optimizing the sound quality.

[0054] Among them, the shielding assembly 14 includes a shielding magnet 141 and a shielding cover 142. The shielding cover 142 has an opening 142a, and the opening 142a faces away from the speaker unit 13. The shielding magnet 141 and the second magnet 11 are received in the shielding cover 142. The shielding cover 142 can serve as a physical barrier to protect the internal second magnet 11 and speaker unit 13 from external impacts and damages. The shielding magnet 141 is located on the side of the second magnet 11 facing away from the opening 142a and is stacked with the second magnet 11. The shielding magnet 141 helps to reduce the electromagnetic interference of the second magnet 11 on the speaker unit 13.

[0055] Furthermore, the arrangement of the N - pole and S - pole of the shielding magnet 141 is the same as that of the corresponding N - pole and S - pole of the second magnet 11. That is to say, the radial magnetization direction of the shielding magnet 141 should be the same as that of the second magnet 11. Such an arrangement can ensure that the magnetic field generated by the shielding magnet 141 repels the magnetic field of the second magnet 11, thereby forming a magnetic "barrier" inside the shielding cover 142 to reduce the influence of electromagnetic interference on the speaker unit 13.
