[0048] The following introduces the embodiments of the present application in conjunction with the accompanying drawings of the specification:

[0049] Reference Figures 1 to 5, The antenna structure according to the embodiments of the present application is applicable to Bluetooth headsets. For example, it can be earclip - type open - back Bluetooth headsets, sports headsets, running headsets, cycling headsets, etc. The antenna structure includes a first connector 100 and a second connector 200. The first connector 100 is used to connect the RF output terminal of the main board 300. The second connector 200 includes a conduction part 210 and an adjustment part 220. The adjustment part 220 is connected to one side of the conduction part 210 close to the first connector 100. The adjustment part 220 is used to electrically connect to the ground terminal of the main board 300. To ensure the radiation performance of the antenna, the adjustment part 220 is movably connected to the first connector 100 to realize the position adjustment of the adjustment part 220 relative to the first connector 100, and further realize the adjustment of the antenna length, so that the antenna length is close to one - quarter of the operating wavelength. The conduction part 210 is spaced from the first connector 100 to prevent the conduction part 210 from contacting the first connector 100 and affecting the antenna length adjustment. Thus, the antenna structure of the present application can adjust the length according to requirements, and on the basis of ensuring the antenna radiation performance, can better adapt to Bluetooth headsets of different sizes and / or shapes.

[0050] Specifically, the second connector 200 can be an FPC (Flexible Printed Circuit), which has the characteristic of flexible deformation. The adjustment part 220 is a wire in the FPC used to connect to the ground terminal of the main board 300, and the adjustment part 220 extends towards the first connector 100 and abuts against the first connector 100. The adjustment part 220 can move relative to the first connector 100 to change the position where it abuts against the first connector 100. The first connector 100 and the second connector 200 together form an Inverted F Antenna (IFA), and other additional structures are not required to meet the requirements of the antenna structure. The antenna structure of the present application forms an antenna with the help of the FPC in the Bluetooth headset, does not occupy additional space inside the Bluetooth headset, and on the basis of meeting the miniaturization of the Bluetooth headset, can also maintain a high level of antenna performance, which is convenient for meeting the design requirements of the miniaturization of the Bluetooth headset.

[0051] It should be noted that the connection between the adjustment part 220 and the first connector 100 is a physical connection, and the two do not need to be electrically connected. The abutment between the adjustment part 220 and the first connector 100 can realize electromagnetic induction between the first connectors 100, and then form an Inverted F antenna structure. When assembling the Bluetooth headset, the antenna structure can also change the position where the adjustment part 220 abuts against the first connector 100 according to the size and / or shape of the Bluetooth headset, ensuring that the antenna length is closer to one - quarter of the operating wavelength of the Bluetooth headset and improving the radiation performance of the antenna structure.

[0052] Reference Figures 1 to 5, in some embodiments, the first connector 100 includes an electromagnetic interaction part 110. One end of the electromagnetic interaction part 110 abuts against the adjusting part 220, and the other end of the electromagnetic interaction part 110 is used to connect to the RF output end. When the length of the antenna reaches or approaches one-quarter of the operating wavelength, that is, when the length of the electromagnetic interaction part 110 is one-quarter of the operating wavelength, the radiation performance of the antenna will be greatly improved. And the operating wavelength is related to the operating frequency of the Bluetooth headset. To ensure that the length of the electromagnetic interaction part 110 is adapted to the operating frequency of the Bluetooth headset, by changing the position where the adjusting part 220 abuts against the first connector 100, the adjustment of the length of the electromagnetic interaction part 110 is realized. The electromagnetic interaction part 110 is used for electrical connection to a Bluetooth module operating at a frequency of 2.4Ghz to 2.5Ghz. The length of the electromagnetic interaction part 110 is 20mm to 25mm, which is used to ensure the radiation performance of the antenna structure.

[0053] Specifically, there is a Bluetooth module on the main board 300, and the operating frequency of the Bluetooth module is 2.4Ghz to 2.5Ghz. When installing the antenna structure, there will be certain losses. Therefore, the length of the electromagnetic interaction part 110 is limited to 20mm to 25mm to avoid reducing the radiation performance of the antenna structure due to the length of the electromagnetic interaction part 110 being too long or too short. For example, the length of the electromagnetic interaction part 110 can be any value among 20mm, 21mm, 22mm, 23mm, 24mm, and 25mm, or a length interval with any two of the above values as the end point values, which is beneficial to further optimizing the radiation performance of the antenna structure.

[0054] It should be noted that when the operating frequency of the Bluetooth module is 2.5Ghz, by changing the position where the adjusting part 220 abuts against the first connector 100, the length of the electromagnetic interaction part 110 is made close to 20mm. When the operating frequency of the Bluetooth module is 2.4Ghz, by changing the position where the adjusting part 220 abuts against the first connector 100, the length of the electromagnetic interaction part 110 is made close to 25mm.

[0055] Reference Figures 1 to 5, in some embodiments, the adjusting portion 220 includes a connecting wall 221, a first abutting wall 222 and a second abutting wall 223. The connecting wall 221 is connected to the conducting portion 210. To ensure there is a gap between the conducting portion 210 and the first connecting member 100, block the electromagnetic induction between the conducting portion 210 and the first connecting member 100, and enable the length of the antenna to be adjusted only through the adjusting portion 220, the connecting wall 221 extends towards the first connecting member 100. The first abutting wall 222 is connected to one end of the connecting wall 221 close to the first connecting member 100, and the second abutting wall 223 is connected to one side of the first abutting wall 222 close to the first connecting member 100. At least one of the first abutting wall 222 and the second abutting wall 223 abuts against the first connecting member 100 to form electromagnetic induction with the first connecting member 100, constituting an inverted-F antenna structure. The first abutting wall 222 and / or the second abutting wall 223 can slide relative to the first connecting member 100 for adjusting the length of the antenna. The first abutting wall 222 and the connecting wall 221 have a first included angle, and the second abutting wall 223 and the first abutting wall 222 have a second included angle, which is beneficial to increasing the contact area between the adjusting portion 220 and the first connecting member 100, ensuring the stability of the electromagnetic induction between the two, and restricting the movement of the conducting portion 210 towards the first connecting member 100, ensuring the length adjustment function of the antenna structure.

[0056] It should be noted that the length of the antenna can be understood as the length of the electromagnetic interaction portion 110, and the upper limit of the antenna length is the length of the first connecting member 100.

[0057] Specifically, the second connecting member 200 can be an FPC. The second connecting member 200 includes a conducting portion 210 and an adjusting portion 220. The conducting portion 210 has multiple wires therein. The wires include a first wire for realizing electrical conduction between the main board 300 and the battery assembly 500, and also include a second wire connected to the grounding end of the main board 300. The second wire is located on the side of the conducting portion 210 close to the first connecting member 100 for further blocking the electromagnetic induction between the first wire and the first connecting member 100, and the second wire is spaced from the first connecting member 100. The adjusting portion 220 is connected to the side of the conducting portion 210 close to the first connecting member 100, and the second wire is electrically connected to the adjusting portion 220. The adjusting portion 220 realizes electrical connection with the grounding end through the second wire. The first included angle can be 90°, and the second included angle can also be 90°, such that the first abutting wall 222 is perpendicular to the connecting wall 221, and the second abutting wall 223 is perpendicular to the first abutting wall 222, that is, the second abutting wall 223 is parallel to the connecting wall 221. The first abutting wall 222 and the second abutting wall 223 form a right-angle structure and abut against the first connecting member 100, thereby constituting an inverted-F antenna structure. By sliding the first abutting wall 222 and the second abutting wall 223 relative to the first connecting member 100, the length of the inverted-F antenna can be adjusted, making the antenna length closer to one-fourth of the operating wavelength and improving the radiation performance of the antenna structure.

[0058] It should be noted that the second connector 200 can only be movably connected to the first connector 100 through the adjusting portion 220. If the second connector 200 abuts against multiple positions of the first connector 100, the function of the adjusting portion 220 to move along the first connector 100 to adjust the antenna length will be damaged. Therefore, the connecting wall 221 is arranged to extend towards the first connector 100 to ensure that there is a barrier between the conducting portion 210 and the first connector 100. Then, at least one of the first abutting wall 222 and the second abutting wall 223 abuts against the first connector 100 to realize an inverted-F antenna, and electromagnetic induction between the conducting portion 210 and the first connector 100 is avoided, which affects the realization of the inverted-F antenna and the adjustment of the antenna length.

[0059] Reference Figures 1 to 5 In some embodiments, the second connector 200 is longer than the first connector 100, and the second connector 200 is a flexible member, such as an FPC. The second connector 200 can be bent inside the Bluetooth headset to make more full use of the space inside the Bluetooth headset. Moreover, the second connector 200 includes a conducting portion 210 and an adjusting portion 220. When the adjusting portion 220 moves relative to the first connector 100 to change the abutting position, the flexible characteristic of the second connector 200 is beneficial to reducing the obstruction of other structures included in the Bluetooth headset to the second connector 200, facilitating the adjustment of the antenna length. At the same time, the second connector 200 being longer than the first connector 100 is beneficial to increasing the moving range of the adjusting portion 220 relative to the first connector 100. Furthermore, the antenna length adjustment range is larger. The increase in the antenna length adjustment range is beneficial to improving the adaptability of the antenna structure to the headset at different operating frequencies.

[0060] Reference Figures 1 to 5 In some embodiments, the first connector 100 is an elastic member. When the antenna structure is installed in an earclip-type open Bluetooth headset, the first connector 100 can provide elasticity to clamp the user's ear to realize the fixation of the headset. Thus, the first connector 100 can not only be used as an antenna to ensure the signal transceiver of the Bluetooth headset, but also be used as a clip for fixation. On the basis of ensuring the wireless performance and elastic clamping function of the open Bluetooth headset, it does not need to additionally occupy the space inside the open Bluetooth headset, which is beneficial to reducing the volume of the open Bluetooth headset.

[0061] Reference Figures 1 to 5, in some other embodiments, to ensure that the user wears the Bluetooth headset more comfortably and stably, the first connecting member 100 may be a memory wire. The memory wire has good elasticity and flexibility, which can better adapt to the ear shapes of different users, avoid causing pain to the user due to excessive clamping force, and avoid the Bluetooth headset falling off due to too small clamping force. In addition, the memory wire has the characteristic of restoring its original shape. After the user removes the Bluetooth headset, the memory wire can quickly restore its original shape without damaging the inherent performance of the memory wire, which is beneficial to extending the service life of the Bluetooth headset.

[0062] Reference Figures 1 to 10 , according to the earphone of the embodiment of the present application, the earphone at least has a wireless communication function. The earphone includes a main board 300, an audio component 400, a battery component 500, and the antenna structure in any of the above embodiments. The main board 300 includes a Bluetooth module, a radio frequency output terminal, and a grounding terminal. The audio component 400 is electrically connected to the main board 300, and the audio component 400 is controlled by the main board 300 to generate sound. The first connecting member 100 is electrically connected to the radio frequency output terminal, the main board 300 is electrically connected to the battery component 500 through the conduction part 210, and the battery component 500 supplies power to the main board 300 through the conduction part 210. The antenna structure can be adjusted to a length suitable for the operating frequency of the Bluetooth module, which is beneficial to ensuring the wireless performance of the earphone.

[0063] Reference Figures 1 to 7 , in some embodiments, the earphone further includes a first part 610, a second part 620, and a third part 630. The first part 610 is connected to one end of the second part 620, and the third part 630 is connected to the other end of the second part 620. The first part 610 is provided with a first accommodation cavity 611, the second part 620 is provided with a second accommodation cavity 621, and the third part 630 is provided with a third accommodation cavity 631. The first accommodation cavity 611 communicates with the second accommodation cavity 621, and the second accommodation cavity 621 is connected to the third accommodation cavity 631. The audio component 400 is located in the first accommodation cavity 611, and the battery component 500 is located in the third accommodation cavity 631, realizing the separation of the audio component 400 and the battery component 500, avoiding electromagnetic interference caused by the power supply of the battery component 500 to the audio component 400, and being beneficial to ensuring the sound quality of the Bluetooth headset. The first connecting member 100 has elasticity, and a part of the first connecting member 100 is located in the second accommodation cavity 621, which not only ensures the clip fixation of the open Bluetooth headset but also ensures the wireless performance of the open Bluetooth headset, enabling the user to obtain a clearer sound quality experience and a more stable wearing experience during sports such as running, fitness, and cycling.

[0064] The main board 300 is located in the first accommodation cavity 611 or the third accommodation cavity 631. When the main board 300 is located in the first accommodation cavity 611, that is, both the main board 300 and the audio component 400 are located in the first accommodation cavity 611, the conduction part 210 extends from the first accommodation cavity 611 through the second accommodation cavity 621 to the third accommodation cavity 631, realizing power supply between the battery assembly 500 and the main board 300. The adjustment part 220 connected to the side of the conduction part 210 close to the first connector 100 abuts against the first connector 100, realizing an inverted F antenna. The antenna structure of the present application can not only realize the power supply and antenna functions, but also provide a magazine fixing function. On the basis of ensuring the antenna performance, it significantly reduces the occupation of the internal space of the Bluetooth headset, facilitating the miniaturization design of the Bluetooth headset. When the main board 300 is located in the third accommodation cavity 631, that is, both the main board 300 and the battery assembly 500 are located in the third accommodation cavity 631, the second connector 200 extends from the third accommodation cavity 631 to the second accommodation cavity 621, and the adjustment part 220 abuts against the first connector 100 in the second accommodation cavity 621.

[0065] It should be noted that the adjustment process of the antenna structure is during the production or repair of the Bluetooth headset. After the Bluetooth headset is assembled into a finished product, the adjustment part 220 is fixed relative to the first connector 100 to ensure that the antenna length remains unchanged and excellent wireless performance is provided. When producing or repairing the Bluetooth headset, the staff can obtain the working wavelength according to the working frequency of the Bluetooth module, then obtain the length of the antenna structure according to the working wavelength, and consider the loss according to the different structures of the Bluetooth headset, and change the position of the adjustment part 220 relative to the first connector 100, so that the length of the electromagnetic interaction part 110 is close to one-fourth of the working wavelength to ensure the wireless performance of the Bluetooth headset.

[0066] Reference Figures 7 to 10 , in some embodiments, the earphone includes a second part 620. The second part 620 is provided with a limiting groove 6211. A part of the conduction part 210 is located in the limiting groove 6211, and the first connector 100 is located outside the limiting groove 6211. The limiting groove 6211 is used to limit the conduction part 210 from moving towards the first connector 100 to avoid electromagnetic induction caused by the contact between the conduction part 210 and the first connector 100, so as to ensure the wireless performance of the earphone.

[0067] It should be noted that during the use of the Bluetooth headset, it will move together with the user. A part of the conduction part 210 located in the limiting groove 6211 can prevent the conduction part 210 from contacting the first connector 100 and damaging the inverted F antenna formed by the abutment of the adjustment part 220 and the first connector 100.

[0068] Reference Figures 6 to 10, in some embodiments, the earphone includes a second part 620. The second part 620 includes a first fixing member 622. Along the length direction of the first connecting member 100, the first connecting member 100 includes opposite first and second ends. The first end is connected to the radio frequency output end, and the second end is connected to the second fixing member 623. The first fixing member 622 is configured as an insulating structure to ensure the insulation of the second end from other structures, effectively blocking the current interference to the first connecting member 100 and improving the anti-interference ability of the Bluetooth earphone. In addition, the first fixing member 622 also defines the direction of the second end, which is beneficial to optimizing the radiation characteristics of the antenna structure and improving the directivity of the antenna structure.

[0069] Reference Figures 6 to 10 , in some embodiments, the second part 620 further includes a second fixing member 623. The second fixing member 623 is connected to one side where the first end faces the second end. The cooperation between the first fixing member 622 and the second fixing member 623 can limit the movement of the first connecting member 100, ensure the stability of the connection between the first connecting member 100 and the radio frequency output end, and limit the movement of the first connecting member 100 towards the conduction part 210, avoiding contact between the first connecting member 100 and the conduction part 210, and ensuring the abutment between the first connecting member 100 and the adjusting part 220, which is beneficial to improving the stability of the antenna structure.
