[0012] As shown in FIG. 1, Figure 1 The smart glasses 1000 can be worn on the head of a wearer, and can be VR (Virtual Reality) glasses, AR (Augmented Reality) glasses, XR (Extender Reality) glasses, MR (Mixed Reality) glasses, or other wearable glasses.

[0013] As shown in FIG. 1, Figure 1As shown, in some embodiments, the smart glasses 1000 includes a frame assembly 300, at least one temple assembly 200, and at least one ear loop 100. At least one temple assembly 200 is connected to the frame assembly 300. At least one ear loop 100 is connected to the end of the temple assembly 200 away from the frame. It is understood that the temple assembly 200 can be placed on the user's ear for stable wearing of the smart glasses 1000; after the smart glasses 1000 is stably worn, the frame assembly 300 can be positioned in front of the user's eyes so that images of the real world can enter the user's field of vision through the frame assembly 300, and / or, the virtual projection effect of the frame assembly 300 can enter the user's field of vision; after the smart glasses 1000 is stably worn, the ear loop 100 can be positioned behind the user's ear to further ensure stable wearing of the smart glasses 1000.

[0014] like Figure 1 As shown, in some embodiments, two temple assemblies 200 are provided, and two frame assemblies 300 are respectively connected to both sides of the frame assembly 300. The two temple assemblies 200 can be respectively mounted on the user's ears on both sides to stably wear the smart glasses 1000. Only one ear hook 100 can be provided. For example, the ear hook 100 is only connected to the end of one temple assembly 200 away from the frame assembly 300, and the end of the other temple assembly 200 away from the frame assembly 300 can be equipped with a counterweight with a weight close to that of the ear hook 100 to ensure stable wearing of the smart glasses 1000. Multiple ear hooks 100 can also be provided, for example, two, with the two ear hooks 100 respectively connected to the ends of the two temple assemblies 200 away from the frame assembly 300.

[0015] like Figure 2 As shown, in some embodiments, the ear hook 100 includes a first housing 10, an antenna module 20, and a control module 30. The control module 30 has a master control function, and is equipped with a master control chip, which can receive signals from various electronic devices and transmit signals to them. Exemplarily, the operations that the control module 30 can perform include, but are not limited to, at least one of the following functions: turning on at least a portion of the circuit, turning off at least a portion of the circuit, turning on the display device in the smart glasses 1000, turning off the display device in the smart glasses 1000, adjusting the parameters of the display device, etc. The antenna module 20 can enable interaction between the smart glasses 1000 and external electronic devices, or enable interaction between electronic devices in other locations on the smart glasses 1000, such as interaction with the display devices on both sides of the smart glasses 1000, to improve the user experience.

[0016] In some embodiments, the first shell 10 has a receiving cavity 10a, and the control module 30 is arranged in the receiving cavity 10a; the antenna module 20 is arranged on the first shell 10 and / or in the receiving cavity 10a. Integrating these electronic devices in the earpiece 100 can make the electronic devices have high integration, facilitate the electrical connection between different electronic devices, and reduce the volume of the whole smart glasses 1000, especially the volume of the temple assembly 200, and improve the wearing comfort.

[0017] As shown in Figure 2 In some embodiments, the antenna module 20 includes a first antenna 21 and a second antenna 22, the first antenna 21 is electrically connected with the control module 30, the second antenna 22 is near-field coupled with the first antenna 21, and the second antenna 22 is electrically isolated from the control module 30. The first antenna 21 serves as a main antenna electrically connected with the control module 30, can receive the electrical signal of the control module 30, and radiate the radio frequency signal outward, or receive the radio frequency signal and convert it into an electrical signal to transmit to the control module 30. Since the second antenna 22 is coupled with the first antenna 21, the second antenna 22 can receive the energy radiated by the first antenna 21 through near-field electromagnetic coupling, generate induced current and magnetic field, and radiate the radio frequency signal outward, or transfer the received radio frequency signal to the first antenna 21 through near-field electromagnetic coupling.

[0018] Near-field coupling is an important electromagnetic phenomenon, which refers to the coupling effect caused by the interaction of electromagnetic fields when the distance between two objects is very close (usually less than half a wavelength). The near-field coupling between the second antenna 22 and the first antenna 21 refers to the electromagnetic induction coupling or magnetic field resonance coupling between the first antenna 21 and the second antenna 22. When transmitting a signal, the electromagnetic field of the first antenna 21 will affect the adjacent second antenna 22. Due to electromagnetic induction, a high-frequency current is generated on the second antenna 22, which in turn radiates a radio frequency signal outward. When receiving a signal, the electromagnetic field of the second antenna 22 will affect the adjacent first antenna 21. Due to electromagnetic induction, a corresponding current is generated on the first antenna 21, which in turn transmits a signal to the control module 30. Electrical isolation refers to isolating the branch circuit from the power supply of the entire electrical system, and there is no direct current or alternating current path between the branch circuit and the entire electrical system, i.e. the branch circuit is isolated from the entire electrical system to become an independent ungrounded safety system. After electrical isolation, the branch circuit and the entire electrical system are mutually insulated. The electrical isolation between the second antenna 22 and the control module 30 means that there is no electrical connection between the second antenna 22 and the control module 30, and the second antenna 22 is not connected to the reference ground of the control module 30. This makes the second antenna 22 become an independent radiation control unit. Electrical isolation ensures that the second antenna 22 can only be excited by near-field electromagnetic coupling, and the working state (resonant frequency, phase, current distribution) is completely determined by its physical properties (size, shape) and its relative position to the main oscillator, which improves the working stability of the second antenna 22, provides extremely precise and stable control dimensions for the design of the second antenna 22, and is more convenient for optimizing the performance of the antenna module 20. It helps to optimize the overall bandwidth, signal stability and direction of the first antenna 21 and the second antenna 22, providing greater freedom for performance optimization of the antenna module 20. It can be understood that if the second antenna 22 is not electrically isolated from the control module 30, the resonant frequency of the second antenna 22 may be fixed, the bandwidth may be narrowed, and it is not conducive to antenna optimization in the limited space of the first shell 10.

[0019] The smart glasses 1000, the antenna module 20 and the control module 30 of the embodiment of the present application are arranged at the hanging ear part 100 of the temple assembly 200 away from the frame assembly 300, so that the electronic devices in the smart glasses 1000 are arranged compactly and reasonably, which is beneficial to reduce the overall volume of the smart glasses 1000 and improve the comfort of the user when wearing. When the user uses the smart glasses 1000, the second antenna 22 is electrically isolated from the control module 30 and is near-field coupled with the first antenna 21, thereby effectively increasing the radiation area, radiation intensity and radiation direction of the antenna. Moreover, since the second antenna 22 and the control module 30 are electrically isolated, the second antenna 22 acts as a parasitic antenna element instead of a parasitic antenna or an antenna ground, which can effectively improve the overall radiation range of the antenna module 20, while reducing the interference of the control module 30 on the antenna signal and improving the radiation stability of the overall antenna module 20. Therefore, the smart glasses 1000 of the present application can enhance the anti-interference capability of the antenna module 20, enhance the antenna signal strength and the stability of the signal.

[0020] As shown in Figure 1 and Figure 8 In some embodiments, the first shell 10 has a first wall surface 101 and a second wall surface 102 arranged opposite in the thickness direction y, a third wall surface 103 and a fourth wall surface 104 arranged opposite in the length direction x, and a fifth wall surface 105 and a sixth wall surface 106 arranged opposite in the height direction z.

[0021] For ease of understanding, the smart glasses 1000 are taken as an example of being worn on the human head, and each direction is explained and described, but the human head does not limit the structure of the present application. The thickness direction y of the first shell 10 refers to the direction from the inside to the outside of the smart glasses 1000, wherein the inside of the smart glasses 1000 is the area enclosed by the frame assembly 300 and the temple assembly 200, and when the smart glasses 1000 are unfolded, the human head is placed in the inside of the smart glasses 1000, and the outside of the smart glasses 1000 is the area outside the area enclosed by the frame assembly 300 and the temple assembly 200; the length direction x of the first shell 10 is the direction from the temple assembly 200 to the hanging ear part 100; and the height direction z of the first shell 10 is the direction substantially perpendicular to the length direction x and the thickness direction y.

[0022] In some embodiments, the mirror frame assembly 300 is provided with a set of mirror leg assemblies 200 and ear hook parts 100 on each side. When the smart glasses 1000 are unfolded, that is, when the mirror leg assemblies 200 are unfolded relative to the mirror frame assembly 300, the ear hook part 100 on one side and the mirror leg assembly 200 connected thereto are oppositely arranged relative to the ear hook part 100 on the other side and the mirror leg assembly 200 connected thereto. Specifically, the first wall surface 101 of the first shell 10 faces away from the other mirror leg assembly 200, the second wall surface 102 faces the other mirror leg assembly 200, the third wall surface 103 faces away from the mirror leg assembly 200 connected with the ear hook part 100, the fourth wall surface 104 faces the mirror leg assembly 200 connected with the ear hook part 100, the fifth wall surface 105 is arranged upward, and the sixth wall surface 106 is arranged downward.

[0023] For example, when the user wears the smart glasses 1000, the first wall surface 101 faces outward away from the head of the human body, the second wall surface 102 faces and / or is attached to the head of the human body, the third wall surface 103 faces the back of the human body, the fourth wall surface 104 faces the front of the human body, the fifth wall surface 105 faces the upper part of the human body, and the sixth wall surface 106 faces the lower part of the human body and / or is attached to the ear of the human body.

[0024] As shown in Figure 2 In some embodiments, the first shell 10 includes a first shell part 11 and a second shell part 12, and the first shell part 11 and the second shell part 12 jointly limit the accommodation cavity 10a. The first shell part 11 has the first wall surface 101, the third wall surface 103, the fourth wall surface 104, the fifth wall surface 105, and the sixth wall surface 106, and the second shell part 12 has the second wall surface 102. The first shell 10 is formed by assembling the first shell part 11 and the second shell part 12, which is simple in structure and facilitates the assembly and arrangement of electronic devices.

[0025] It can be understood that, since the first shell part 11 is recessed to form the first accommodation cavity, the first shell part 11 has an inner wall surface recessed to form the first accommodation cavity and an outer wall surface facing away from the first accommodation cavity. According to different arrangements of the first antenna 21 and the second antenna 22 on the inner side or the outer side of the first shell part 11, the inner wall surface or the outer wall surface of the first shell part 11 can be respectively provided with the first wall surface 101, the third wall surface 103, the fourth wall surface 104, the fifth wall surface 105, and the sixth wall surface 106. Similarly, the second shell part 12 can also be provided with a second accommodation cavity for jointly accommodating electronic devices with the first accommodation cavity. Correspondingly, the second wall surface 102 is arranged on the inner wall surface of the second shell part 12 provided with the second accommodation cavity or the outer wall surface facing away from the second accommodation cavity. In some embodiments, the second shell part 12 is only a flat plate, and the second wall surface 102 is arranged on the side of the second shell part 12 close to or away from the first shell part 11. In this way, the first shell part 11 and the second shell part 12 are connected to limit the accommodation cavity 10a, so as to accommodate electronic devices such as the control module 30.

[0026] In some embodiments, the first shell part 11 is connected to the second shell part 12 by at least one of clamping, bonding or screwing. The first shell part 11 and the second shell part 12 are stably connected by the above-mentioned manners, ensuring that the structure of the ear-hanging part 100 is firm and reliable.

[0027] As shown in FIGS. 1, 2 and 3, in some embodiments, the first antenna 21 is arranged on at least one of the first wall surface 101, the third wall surface 103 and the fifth wall surface 105. Arranging the first antenna 21 on at least one of the first wall surface 101, the third wall surface 103 and the fifth wall surface 105 can ensure that the first antenna 21 can radiate or receive radio frequency signals in the length direction x, the thickness direction y and the height direction z of the first shell 10, thereby improving the effect of the antenna module 20 on radiating or receiving radio frequency signals outward. The first antenna 21 can be arranged on only one of the first wall surface 101, the third wall surface 103 or the fifth wall surface 105, or can be arranged on any two wall surfaces or all three wall surfaces, without limitation. Figure 3 Figure 8 Since the first antenna 21 is arranged on at least one of the first wall surface 101, the third wall surface 103 and the fifth wall surface 105, it can be seen that the first antenna 21 is arranged on the first shell part 11. Therefore, when arranging the antenna module 20, the antenna module 20 only needs to be arranged on the first shell part 11, and the second shell part 12 is only used for closing and assembling. Therefore, the convenience of manufacturing and assembling the ear-hanging part 100 of the smart glasses 1000 is improved.

[0028] In combination with the foregoing, when the user wears the smart glasses 1000, arranging the first antenna 21 on the first wall surface 101 can ensure that the first antenna 21 can radiate or receive radio frequency signals outward in the thickness direction y. Since the outer side of the ear-hanging part 100 away from the human head is not blocked, the interference with the antenna signal can be reduced, and the signal strength and stability of the antenna signal are ensured. Since the second wall surface 102 faces and / or is attached to the human head, arranging the first antenna 21 on the second wall surface 102 will interfere with the signal strength of the first antenna 21 due to the human head. Therefore, arranging the first antenna 21 on the second wall surface 102 will increase the cost and have poor effect.

[0029] In combination with the foregoing, when the user wears the smart glasses 1000, arranging the first antenna 21 on the first wall surface 101 can ensure that the first antenna 21 can radiate or receive radio frequency signals outward in the thickness direction y. Since the outer side of the ear-hanging part 100 away from the human head is not blocked, the interference with the antenna signal can be reduced, and the signal strength and stability of the antenna signal are ensured. Since the second wall surface 102 faces and / or is attached to the human head, arranging the first antenna 21 on the second wall surface 102 will interfere with the signal strength of the first antenna 21 due to the human head. Therefore, arranging the first antenna 21 on the second wall surface 102 will increase the cost and have poor effect.

[0030] ​When the first antenna 21 is placed on the third wall 103, it can be ensured that the first antenna 21 can radiate or receive radio frequency signals in the length direction x. Since there is no obstruction behind the earpiece 100, interference with the antenna signal can be reduced, ensuring the antenna signal strength and signal stability. Since the fourth wall 104 faces the temple assembly 200, if the first antenna 21 is placed on the fourth wall 104, the temple assembly 200 will interfere with the signal strength of the first antenna 21. Therefore, placing the first antenna 21 on the fourth wall 104 will increase costs and have poor effect. Of course, in actual production applications, the first antenna 21 can be placed on the fourth wall 104 as needed, without restriction.

[0031] When the first antenna 21 is placed on the fifth wall 105, it can be ensured that the first antenna 21 can radiate or receive radio frequency signals upward in the height direction z. Since there is no obstruction above the ear 100, interference with the antenna signal can be reduced, ensuring the antenna signal strength and signal stability. Since the sixth wall 106 faces downward towards the human body and / or is attached to the human ear, if the first antenna 21 is placed on the sixth wall 106, the signal strength of the first antenna 21 will be interfered with by the human ear. Therefore, placing the first antenna 21 on the sixth wall 106 will increase costs and have poor effect. Of course, in actual production applications, the first antenna 21 can also be placed on the sixth wall 106 as needed, without restriction.

[0032] like Figure 3 and Figure 8 As shown, in some embodiments, the second antenna 22 is disposed on at least one of the first wall surface 101 and the third wall surface 103. Disposing the second antenna 22 on at least one of the first wall surface 101, the third wall surface 103, and the fifth wall surface 105 ensures that the second antenna 22 can radiate or receive radio frequency signals in the length direction x, thickness direction y, and height direction z of the first housing 10, thereby improving the effect of the antenna module 20 in radiating or receiving radio frequency signals. The second antenna 22 can be disposed on only the first wall surface 101, the third wall surface 103, or the fifth wall surface 105, or on a combination of two or all three walls; there is no limitation.

[0033] Since the second antenna 22 is located on at least one of the first wall surface 101, the third wall surface 103, and the fifth wall surface 105, it can be seen that the second antenna 22 is located on the first housing 11. Thus, when arranging the antenna module 20, it is only necessary to place the antenna module 20 on the first housing 11, and the second housing 12 is only closed and assembled. Therefore, the convenience of manufacturing and assembling the smart glasses 1000 on the ear hook 100 is improved.

[0034] In combination with the foregoing, when the user wears the smart glasses 1000, the second antenna 22 is arranged on the first wall surface 101, which can ensure that the second antenna 22 can radiate or receive radio frequency signals outward in the thickness direction y. Since the outer side of the ear-hanging part 100 away from the human head is not blocked, the interference with the antenna signal can be reduced, and the antenna signal strength and signal stability are ensured.

[0035] When the second antenna 22 is arranged on the third wall surface 103, it can be ensured that the second antenna 22 can radiate or receive radio frequency signals backward in the length direction x. Since the rear of the ear-hanging part 100 is not blocked, the interference with the antenna signal can be reduced, and the antenna signal strength and signal stability are ensured. Since the fourth wall surface 104 is the temple assembly 200, if the second antenna 22 is arranged on the fourth wall surface 104, the signal strength of the second antenna 22 will be interfered by the temple assembly 200. Therefore, arranging the second antenna 22 on the fourth wall surface 104 will increase the cost and have poor effect. Of course, in actual production and application, the second antenna 22 can be arranged on the fourth wall surface 104 according to the needs, without limitation.

[0036] When the second antenna 22 is arranged on the fifth wall surface 105, it can be ensured that the second antenna 22 can radiate or receive radio frequency signals upward in the height direction z. Since the upper side of the ear-hanging part 100 is not blocked, the interference with the antenna signal can be reduced, and the antenna signal strength and signal stability are ensured. Since the sixth wall surface 106 is downward toward the human body and / or is attached to the ear of the human body, if the second antenna 22 is arranged on the sixth wall surface 106, the signal strength of the second antenna 22 will be interfered by the ear of the human body. Therefore, arranging the second antenna 22 on the sixth wall surface 106 will increase the cost and have poor effect. Of course, in actual production and application, the second antenna 22 can be arranged on the sixth wall surface 106 according to the needs, without limitation.

[0037] As shown in FIG. 1, Figure 3 It can be understood that the first antenna 21 and the second antenna 22 are both arranged on the first shell 10, and the first antenna 21 is not arranged in the area where the second antenna 22 is arranged on the first shell 10, and the second antenna 22 is not arranged in the area where the first antenna 21 is arranged on the first shell 10. In this way, the first antenna 21 and the second antenna 22 can be arranged in a larger area on the first shell 10 without increasing the cost, thereby improving the radiation area and direction of the antenna signal.

[0038] As shown in FIG. 1, Figure 3As shown in some embodiments, the second antenna 22 is arranged on the side of the control module 30 away from the second wall surface 102. When the second antenna 22 radiates or receives radio frequency signals outward, it can avoid the interference of the control module 30 on the antenna signals, thereby improving the radiation intensity of the antenna signals.

[0039] As shown in some embodiments, the first antenna 21 is arranged on the side of the control module 30 away from the second wall surface 102. When the first antenna 21 radiates or receives radio frequency signals outward, it can avoid the interference of the control module 30 on the antenna signals, thereby improving the radiation intensity of the antenna signals. Figure 3 As shown in some embodiments, the control module 30 is arranged close to the second wall surface 102. In this way, the control module 30 can further avoid interfering with the first antenna 21 and / or the second antenna 22, thereby improving the antenna signal intensity and signal stability of the smart glasses 1000.

[0040] Figure 3 As shown in some embodiments, the control module 30 is arranged at the connecting position between the first shell part 11 and the second shell part 12 along the thickness direction y. In this way, the control module 30 can be arranged close to the second wall surface 102, and the first antenna 21 and / or the second antenna 22 can be arranged on the side of the control module 30 away from the second wall surface 102, thereby improving the antenna signal intensity and signal stability of the smart glasses 1000.

[0041] As shown in some embodiments, the control module 30 is arranged at the connecting position between the first shell part 11 and the second shell part 12 along the thickness direction y. In this way, the control module 30 can be arranged close to the second wall surface 102, and the first antenna 21 and / or the second antenna 22 can be arranged on the side of the control module 30 away from the second wall surface 102, thereby improving the antenna signal intensity and signal stability of the smart glasses 1000.

[0042] As shown in some embodiments, the ear-hanging part 100 further comprises a battery module 80 electrically connected to the control module 30 and arranged on the side of the control module 30 away from the second wall surface 102. At least part of the first antenna 21 is arranged on the fifth wall surface 105, and at least part of the first antenna 21 is arranged side by side with the battery module 80 along the length direction x. The battery module 80 can supply power to the control module 30 and other electronic devices of the smart glasses 1000, facilitating the carrying and use of the smart glasses 1000. Moreover, arranging the battery module 80 on the ear-hanging part 100 can balance the front and rear ends of the temple assembly 200, thereby balancing the center of gravity of the smart glasses 1000 and improving the wearing comfort of the user. Arranging the first antenna 21 on the fifth wall surface 105 can make full use of the space of the first shell 10 to improve the antenna signal intensity, and can also ensure that the first antenna 21 is far away from the interference of the control module 30, thereby improving the radiation intensity and radiation range of the antenna. Figure 2 As shown in some embodiments, the battery module 80 is arranged in the first accommodating cavity of the first shell part 11. In this way, the battery module 80 is located between the antenna module 20 and the control module 30, and the control module 30 is far away from the antenna module 20, thereby improving the radiation intensity of the antenna signals and the signal stability.

[0043] As shown in some embodiments, the battery module 80 is arranged in the first accommodating cavity of the first shell part 11. In this way, the battery module 80 is located between the antenna module 20 and the control module 30, and the control module 30 is far away from the antenna module 20, thereby improving the radiation intensity of the antenna signals and the signal stability.

[0044] ​like Figure 2 As shown, in some embodiments, the earpiece 100 further includes a battery module 80, at least a portion of the second antenna 22 is disposed on the fifth wall surface 105, and at least a portion of the first antenna 21 is disposed parallel to the battery module 80 along the length direction x. Disposing the second antenna 22 on the fifth wall surface 105 can fully utilize the space of the first housing 10 to improve antenna signal strength, while also ensuring that the first antenna 21 is kept away from interference from the control module 30, thereby improving the radiation intensity and range of the antenna signal.

[0045] like Figure 3 and Figure 8 As shown, in some embodiments, the first antenna 21 extends at least partially to the first wall surface 101. It can be understood that the first antenna 21 is mainly disposed on other walls, with a portion extending to the first wall surface 101, allowing at least a portion of the first antenna 21 to radiate radio frequency signals outward in the thickness direction y. Since the ear hook 100 is unobstructed from the outside of the human head, interference with the antenna signal can be reduced, ensuring sufficient antenna signal strength and signal stability.

[0046] like Figure 3 and Figure 8 As shown, in some embodiments, the second antenna 22 extends at least partially to the first wall surface 101. It can be understood that the second antenna 22 is primarily disposed on other walls, with a portion extending to the first wall surface 101, allowing at least a portion of the second antenna 22 to radiate radio frequency signals outward in the thickness direction y. Since the ear hook 100 is unobstructed from the outside of the human head, interference with the antenna signal can be reduced, ensuring sufficient antenna signal strength and signal stability.

[0047] like Figure 3 and Figure 8 As shown, in some embodiments, the first antenna 21 is disposed on the third wall surface 103, and a portion of the first antenna 21 extends to the first wall surface 101; the second antenna 22 is disposed on the fifth wall surface 105, with the portion of the second antenna 22 on the fifth wall surface 105 extending along the length direction x of the first housing 10, and a portion of the second antenna 22 extending to the first wall surface 101. The second antenna 22 and the portion of the first antenna 21 extending to the first wall surface 101 are near-field coupled. The first antenna 21 and the second antenna 22 can be arranged together on the first wall surface 101, the third wall surface 103, and the fifth wall surface 105, which can improve the radiation intensity and radiation range of the antenna signal, and improve the antenna signal strength and signal stability. Furthermore, the position of the first antenna 21 away from the temple assembly 200 results in better signal reception, further avoiding interference from other electronic devices and improving signal stability.

[0048] Exemplarily, one end of the second antenna 22 is close to the third wall surface 103 along the length direction x of the first housing 10, and the other end is close to the first wall surface 101, so that the second antenna 22 can be set to a sufficient length to improve the radiation intensity and radiation range of the antenna signal.

[0049] Exemplarily, the end of the second antenna 22 close to the third wall surface 103 has a coupling gap at the first wall surface 101, and the part of the first antenna 21 extending to the first wall surface 101 is disposed at the coupling gap and has a spacing from the second antenna 22, so that the second antenna 22 can be near-field coupled with the part of the first antenna 21 extending to the first wall surface 101, and the second antenna 22 can thus receive the energy radiated by the first antenna 21 through near-field electromagnetic coupling, generate induced current, and radiate radio frequency signals outward. In some embodiments, the end of the first antenna 21 away from the third wall surface 103 can have a coupling gap at the first wall surface 101, and the part of the second antenna 22 extending to the first wall surface 101 is disposed at the coupling gap and has a spacing from the first antenna 21, so that the first antenna 21 can be near-field coupled with the part of the second antenna 22 extending to the first wall surface 101, and the second antenna 22 can thus receive the energy radiated by the first antenna 21 through near-field electromagnetic coupling, generate induced current, and radiate radio frequency signals outward.

[0050] In further examples, the part of the second antenna 22 also extends to the fourth wall surface 104 to further increase the radiation intensity and radiation range of the antenna. Further, when the microphone hole is provided on the fourth wall surface 104, the part of the second antenna 22 extending to the fourth wall surface 104 also needs to avoid the microphone hole to avoid the influence of the microphone on the signal receiving and transmitting of the second antenna 22.

[0051] As Figure 1 shown, in some embodiments, the ear-hanging part 100 further includes a touch circuit board 50. The touch circuit board 50 is electrically connected with the control module 30, and the user can perform corresponding control operations on the smart glasses 1000 by touching the touch circuit board 50. The touch circuit board 50 is disposed on the first wall surface 101 to facilitate the user to perform the touch operation. When the first antenna 21 and / or the second antenna 22 is disposed on the first wall surface 101, the first antenna 21 and / or the second antenna 22 has a first avoiding gap, and the touch circuit board 50 is disposed at the first avoiding gap, so that the touch circuit board 50 and the antenna module 20 can be reasonably and compactly disposed on the ear-hanging part 100, and the weight and volume of the ear-hanging part 100 can be effectively reduced.

[0052] In some embodiments, the second antenna 22 is a parasitic antenna element, which is used to improve or extend the performance of the original antenna, especially in terms of frequency coverage and bandwidth. Specifically, the bandwidth can be determined by the ratio of the thickness to the wavelength d / λ of the parasitic antenna element, where d is the diameter or equivalent diameter of the parasitic antenna element, and λ is the wavelength corresponding to the operating frequency of the antenna. When λ is constant, the larger the diameter d, the greater the bandwidth, and the smaller the diameter d, the smaller the bandwidth.

[0053] As shown in FIG. 1, in some embodiments, the length a of the second antenna 22 along the length direction x satisfies: 20mm≤a≤35mm. By limiting the length a of the second antenna 22 along the length direction x, the antenna radiation energy can be accurately focused in the desired radiation direction, the antenna performance is optimized, and the second antenna 22 has sufficient length in the length direction x of the first shell 10 to improve the antenna radiation intensity and radiation range without exceeding the size of the first shell 10 itself. Figure 3 For example but not limited to, the length a of the second antenna 22 satisfies 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm or a range value composed of any two numerical values.

[0054] As shown in FIG. 1, in some embodiments, the length b of the second antenna 22 along the thickness direction y satisfies: 4mm≤b≤10mm. By limiting the length b of the second antenna 22 along the thickness direction y, the antenna radiation energy can be accurately focused in the desired radiation direction, the antenna performance is optimized, and the second antenna 22 has sufficient length in the thickness direction y of the first shell 10 to improve the antenna radiation intensity and radiation range without exceeding the size of the first shell 10 itself.

[0055] Figure 3 For example but not limited to, the length b of the second antenna 22 satisfies 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or a range value composed of any two numerical values.

[0056] As shown in FIG. 1, in some embodiments, the length c of the second antenna 22 along the height direction z satisfies: 5mm≤c≤10mm. By limiting the length c of the second antenna 22 along the height direction z, the antenna radiation energy can be accurately focused in the desired radiation direction, the antenna performance is optimized, and the second antenna 22 has sufficient length in the height direction z of the first shell 10 to improve the antenna radiation intensity and radiation range without exceeding the size of the first shell 10 itself.

[0057] For example but not limited to, the length c of the second antenna 22 satisfies 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or a range value composed of any two numerical values. Figure 3 As shown in FIG. 1, in some embodiments, the length c of the second antenna 22 along the height direction z satisfies: 5mm≤c≤10mm. By limiting the length c of the second antenna 22 along the height direction z, the antenna radiation energy can be accurately focused in the desired radiation direction, the antenna performance is optimized, and the second antenna 22 has sufficient length in the height direction z of the first shell 10 to improve the antenna radiation intensity and radiation range without exceeding the size of the first shell 10 itself.

[0058] ​For example, but not limited to, the length c of the second antenna 22 satisfies 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or any two values in the range.

[0059] It should be noted that the length a of the second antenna 22 along the length direction x refers to the maximum straight line distance of the two ends of the second antenna 22 along the length direction x. Since the second antenna 22 can be provided with a groove according to the radiation frequency, the actual length of the current flowing through can be greater than the length a. The length b of the second antenna 22 along the thickness direction y refers to the maximum straight line distance of the edge of the second antenna 22 along the thickness direction y. Since the second antenna 22 can be extended from the first wall surface 101 to the fifth wall surface 105, the actual length of the current flowing in the thickness direction y can be greater than the length b. Similarly, the length c of the second antenna 22 along the height direction z refers to the maximum straight line distance of the edge of the second antenna 22 along the height direction z. Since the second antenna 22 can be extended from the fifth wall surface 105 to the fourth wall surface 104, the actual length of the current flowing in the height direction z can be greater than the length c.

[0060] In some embodiments, the first antenna 21 is etched on the circuit board in a snake shape, an inverted F type (PIFA antenna) or a meander line (Meander) structure, so as to increase the equivalent length of the circuit path. In this way, without increasing the overall size of the circuit board, the effective control and radiation of the electromagnetic wave of a specific frequency band can be realized through the circuit path in a roundabout way. Preferably, the first antenna 21 is a PIFA antenna, which is a Planar Inverted F Shaped Antenna. The PIFA antenna adopts a planar radiation unit as a radiator and a large ground as a reflecting surface, and has the advantages of compact structure, stable performance and easy integration.

[0061] For example, but not limited to, the length c of the second antenna 22 satisfies 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or any two values in the range. Figure 7 ​As shown in some embodiments, the antenna module 20 further comprises a first connecting member 215, the first antenna 21 comprises an inner antenna 211 and an outer antenna 212, the inner antenna 211 is arranged in the accommodating cavity 10a defined by the first shell 10, the outer antenna 212 is arranged on the outer wall of the first shell 10, the first connecting member 215 is configured to pass through the accommodating cavity 10a to the outer wall to connect the inner antenna 211 and the outer antenna 212, and the second antenna 22 is arranged on the outer wall of the first shell 10 and is near-field coupled with the outer antenna 212. The inner antenna 211 receives the electrical signal of the control module 30 and transmits the electrical signal to the outer antenna 212 through the first connecting member 215, and the second antenna 22 receives the energy of the outer antenna 212 by receiving near-field coupling, generates induced current, and radiates radio frequency signals outward. The outer antenna 212 and the second antenna 22 are both arranged on the outer wall of the first shell 10, which can reduce the obstruction of the first shell 10 to the antenna signal, thereby further enhancing the antenna signal strength and the stability of the signal. Among them, the inner antenna 211 can be an antenna arranged on the inner wall of the first shell 10 by laser engraving, printing or embedding, or a flexible circuit board arranged in the accommodating cavity 10a, as long as it can realize electrical connection with the control module 30 and the first connecting member 215. It can be understood that in some embodiments, the ear hook portion 100 can also be provided with a protective layer such as rubber on the side away from the first shell 10 to protect the outer antenna 212.

[0062] As shown in some embodiments, Figure 3 and Figure 5 As shown in some embodiments, part of the inner antenna 211 is attached to the inner wall of the first shell 10, and part extends towards the accommodating cavity 10a to be electrically connected with the control module 30. The part of the inner antenna 211 attached to the inner wall of the first shell 10 is connected with the outer antenna 212 through the first connecting member 215 to transmit the electrical signal to the outer antenna 212, while the connection stability can be improved.

[0063] As shown in some embodiments, Figure 3As shown, in some embodiments, the control module 30 comprises a first feeding point and a first grounding point, the first antenna 21 is provided with a second feeding point and a second grounding point, the second feeding point is electrically connected with the first feeding point, and the second grounding point is electrically connected with the first grounding point, so that the first antenna 21 is connected to the reference ground of the control module 30. By electrically connecting the second feeding point and the first feeding point, the first antenna 21 can receive the electrical signal of the control module 30 and radiate the radio frequency signal, or convert the received radio frequency signal into an electrical signal and transmit it to the control module 30; the reference ground refers to the common reference point of the internal circuit operation and the measurement voltage of the control module 30, the potential of this point is specified as 0 volt, the reference ground is used as the main grounding network connecting various components and metal parts, and is the "anchor point" and "sea level" of the entire device circuit, a special copper layer can be included in the control module 30 as a ground layer as the reference ground, the first grounding point is connected to the ground layer, and then the second grounding point and the first grounding point are electrically connected, so that the "ground" of different devices and metals is equipotential in radio frequency, so as to stabilize the reference point, suppress interference, and improve the stability of the first antenna 21. In some embodiments, the reference ground in the control module 30 can comprise a plurality of ground layers, according to the difference in function, each ground layer can be divided into a surface ground layer mainly used for conducting current and a shielding ground layer mainly used for reflecting radio frequency signals and shielding interference, and the shielding ground layer can also be provided with no less than two layers according to the shielding needs.

[0064] In some embodiments, the first antenna 21 is a PIFA antenna, the inner side antenna 211 includes a first inner side antenna and a second inner side antenna, the first inner side antenna has a portion attached to the inner wall of the first shell 10 and a portion extending towards the accommodating cavity 10a, the control module 30 is provided with a first spring 213 (SMT spring), and a second feeding point of the portion of the first inner side antenna extending towards the accommodating cavity 10a is connected and conducted with a first feeding point of the control module 30 through the first spring 213 and the first feeding point of the control module 30, so that the first inner side antenna can transmit electrical signals between the control module 30. The second inner side antenna has a portion attached to the inner wall of the first shell 10 and a portion extending towards the accommodating cavity 10a, the control module 30 is provided with a second spring 214 (SMT spring), and a second grounding point of the portion of the second inner side antenna extending towards the accommodating cavity 10a is connected and conducted with a first grounding point of the control module 30 through the second spring 214 and the first grounding point of the control module 30, which on the one hand stabilizes the reference point and suppresses interference, and on the other hand, the reference ground is a mirror image of the first antenna 21, together with the antenna arm to form a complete dipole, which collectively radiates and receives electromagnetic waves. Specifically, the high-frequency alternating current flows in the first antenna 21, which produces a changing electric field and magnetic field, and the reference ground provides a clear and controllable return path and boundary for these electromagnetic fields. The reference ground acts as a "mirror" and, together with the first antenna 21 connected to the first feeding point, forms a transmission line structure, ensuring that energy can be effectively transmitted from the radio frequency chip to the first antenna 21 and the second antenna 22 and radiated out, rather than randomly roaming in the control module 30 and causing interference. Further, the outer side antenna 212 has a first connecting portion and a second connecting portion, and the first connecting member 215 includes two parts, one part connecting the first connecting portion and the first inner side antenna, and the other part connecting the second connecting portion and the second inner side antenna.

[0065] In some embodiments, the total length d of the outer side antenna 212 and the inner side antenna 211 satisfies: 10mm≤d≤20mm. It should be noted that the total length d of the outer side antenna 212 and the inner side antenna 211 refers to the distance from the feeding point of the inner side antenna 211 to the farthest end of the outer side antenna 212 away from the inner side antenna 211. By limiting the total length d, the first antenna 21 can be matched to the target frequency band, and the antenna can be miniaturized to be more reasonably arranged in the hanging ear portion 100 and to enhance the signal strength of the radiation and improve the user's experience.

[0066] For example but not limited to, the total length d of the outer side antenna 212 and the inner side antenna 211 satisfies 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm or any range value composed of any two numerical values.

[0067] Exemplarily, the actual total length d of the outer antenna 212 and the inner antenna 211 can be determined according to a 1 / 4 wavelength antenna, a 1 / 8 wavelength antenna, or a 1 / 12 wavelength antenna, so as to efficiently transmit or receive wireless signals of a specific wavelength. In some embodiments, the first antenna 21 as the main antenna and the second antenna 22 as the parasitic antenna oscillator cooperate with each other, so as to improve the radiation capability of the whole antenna while realizing the miniaturization of the antenna.

[0068] In some embodiments, at least part of the first antenna 21 is etched, printed, or embedded in the shell wall of the first shell 10. Exemplarily, the process of etching the first antenna 21 on the shell wall of the first shell 10 can be LDS (Laser Direct Structuring). Specifically, LDS is to perform laser activation on the surface of the shell wall of the first shell 10 to generate a microscopically rough surface with high adhesion, and then deposit and penetrate the laser-processed first antenna 21 on the surface.

[0069] Exemplarily, the process of printing the first antenna 21 on the shell wall of the first shell 10 can be at least one of PDS (Print Direct Structuring) and LRP (Laser Restructuring Printing). Specifically, PDS is a process of printing a circuit on the shell wall of the first shell 10 with silver paste, and LRP is to form a three-dimensional circuit shape by precisely coating conductive silver paste on the surface of the shell wall of the first shell 10 at high speed, and then trimming by three-dimensional control laser to form a high-precision circuit interconnection structure.

[0070] Exemplarily, the first antenna 21 is embedded in the shell wall of the first shell 10, specifically, a mounting groove corresponding to the first antenna 21 can be formed on the surface of the shell wall of the first shell 10, and the first antenna 21 is embedded and mounted in the mounting groove. The embedding can be realized by any suitable way such as clamping and bonding, which is not limited here.

[0071] In some embodiments, the inner antenna 211 is etched, printed, or embedded in the inner wall of the first shell 10. The specific process can be referred to the above, so as to fully utilize the morphology of the ear hook part 100, effectively reduce the weight and volume of the ear hook part 100, reduce the structural risks such as loose fitting and long-term use aging of the inner antenna 211, so that the function of the inner antenna 211 has higher stability, higher antenna signal strength, and antenna thickness. Exemplarily, at least part of the inner antenna 211 is etched, printed, or embedded in the inner wall of the first shell 11.

[0072] In some embodiments, the outer antenna 212 is etched, printed or embedded on the inner wall of the first shell 10. The specific process can refer to the above, so that the form of the ear part 100 itself can be fully utilized, effectively reducing the weight and volume of the ear part 100, reducing the structural risks such as loose fitting of the inner antenna 211 or long-term use aging, so that the function of the inner antenna 211 has higher stability, higher antenna signal strength and antenna thickness. Illustratively, the outer antenna 212 is etched, printed or embedded on the outer wall of the first shell 11.

[0073] In some embodiments, at least part of the second antenna 22 is etched, printed or embedded on the shell wall of the first shell 10.

[0074] Illustratively, the process of etching the second antenna 22 on the shell wall of the first shell 10 can be LDS (Laser Direct Structuring, laser etching process). Specifically, LDS is to perform laser activation on the surface of the shell wall of the first shell 10 to generate a microscopically rough surface with high adhesion, and then deposit and penetrate the first antenna 21 treated by laser on the surface.

[0075] Illustratively, the process of printing the second antenna 22 on the shell wall of the first shell 10 can be at least one of PDS (Print Direct Structuring, printing forming process) and LRP (Laser Restructuring Printing, laser restructuring printing). Specifically, PDS is a process of printing a circuit on the shell wall of the first shell 10 with silver paste, and LRP is a three-dimensional printing process that applies conductive silver paste to the surface of the shell wall of the first shell 10 at high speed and precision to form a three-dimensional circuit shape, and then uses three-dimensional control laser trimming to form a high-precision circuit interconnection structure.

[0076] Illustratively, the second antenna 22 is embedded in the shell wall of the first shell 10, which can be specifically: a mounting groove corresponding to the second antenna 22 is formed on the surface of the shell wall of the first shell 10, and the first antenna 21 is embedded and mounted in the mounting groove.

[0078] As Figure 5As shown, in some embodiments, the temple assembly 200 comprises a second housing 201 extending along the length direction x, the second housing 201 is at least partially configured as metal, and the metal part of the second housing 201 is electrically connected to the reference ground of the control module 30. It can be understood that the temple assembly 200 is longer than the ear hook part 100 and is more likely to contact the head of the wearer. By configuring the second housing 201 as metal at least in part and electrically connecting it to the reference ground of the control module 30, the system safety (anti-static), stable reference potential, interference suppression, antenna ground length extension, and signal strength enhancement can be improved, and the signal absorption of the human head can be reduced. Moreover, the ground plane provides a low impedance discharge path for electrostatic discharge, preventing the radio frequency front end from being broken down. In addition, by using the metal part of the second housing 201 as the antenna ground, which becomes part of the entire antenna, the position and fixation method of the antenna ground do not need to be considered, which is very convenient for design, and additional antenna ground does not need to be assembled during production and assembly, which is beneficial for mass production.

[0079] Exemplarily, the second housing 201 is configured as metal as a whole, so as to further suppress interference, extend the length of the antenna ground, and enhance the signal strength of the antenna.

[0080] Exemplarily, the second housing 201 comprises a third housing part and a fourth housing part, both of which extend along the length direction x of the temple assembly 200, the third housing part and the fourth housing part are connected to obtain the second housing 201, and a cavity formed between the third housing part and the fourth housing part can be used to arrange other electronic devices, for example, to mount the connecting circuit board 202. The third housing part and / or the fourth housing part are configured as metal, so as to suppress interference, extend the length of the antenna ground, and enhance the signal strength of the antenna.

[0081] In some embodiments, one end of the second housing 201 is electrically connected to the reference ground of the control module 30, and the other end is insulatedly connected to the frame assembly 300, so as to only allow the temple to participate in radiation and become part of the antenna.

[0083] Exemplarily, in some embodiments, the other end of the second housing 201 is connected to the frame by using insulating plastic.

[0084] In some embodiments, the first shell part 11 and the second shell part 12 further have an opening communicating with the accommodating cavity 10a, and the second shell 201 can be arranged in the opening to be connected with the reference ground of the control module 30.

[0085] Exemplarily, the second shell 201 and the first shell part 11 and / or the second shell part 12 are fastened by at least one of clamping, bonding or screwing to ensure the stable connection between the temple assembly 200 and the ear-hanging part 100.

[0086] As shown in the figures, Figure 5 In some embodiments, the smart glasses 1000 further include a connecting circuit board 202 arranged in the frame assembly 300 and the temple assembly 200, and the connecting circuit board 202 is electrically connected to the reference ground of the control module 30. The control module 30 can connect other electronic devices of the smart glasses 1000 through the connecting circuit board 202 to control and interact with the other electronic devices of the smart glasses 1000. Since the first antenna 21 is also connected to the reference ground of the control module 30, the connecting circuit board 202 and the electronic devices connected thereto have the same reference ground as the antenna, so that the reference potential can be stabilized, the interference can be suppressed, and the stability of the antenna can be improved.

[0087] Exemplarily, the connecting circuit board 202 is provided with a first connector 2021 at one end close to the control module 30, and the control module 30 is provided with a second connector at one end close to the temple assembly 200, and the first connector 2021 and the second connector are connected to realize the electrical connection between the connecting circuit board 202 and the control module 30, and the connecting circuit board 202 can be connected to the reference ground of the control module 30.

[0088] In some embodiments, the connecting circuit board 202 is a flexible circuit board which can be bent so that the connecting circuit board 202 can deform with the deformation of the temple assembly 200, so that the temple assembly 200 of the smart glasses 1000 can be adapted to the head of a human body. Further, the connecting circuit board 202 is also arranged in the frame assembly 300 so that the connecting circuit board 202 can connect the electronic devices in the frame to supply power and communicate with the electronic devices in the frame. The connecting circuit board 202 can also bend with the rotation of the temple assembly 200 relative to the frame assembly 300 to ensure the stable electrical connection between the connecting circuit board 202 and the electronic devices in the frame.

[0089] In some embodiments, the first shell part 11 and the second shell part 12 further have an opening communicating with the accommodating cavity 10a, and the connecting circuit board 202 can be arranged in the opening to be connected with the reference ground of the control module 30.

[0090] As shown in the figures, Figure 4 and Figure 6As shown, in some embodiments, the ear hook 100 further comprises a reflection component 40, which is arranged on the side of the control module 30 away from the first wall surface 101, and is connected to the reference ground of the control module 30. The reflection component 40 is used to reflect the radio frequency signals emitted by the antenna module 20. The reflection component 40 is close to the side of the human head, and is used to reflect the radio frequency signals emitted by the antenna module 20, so that the radio frequency signals emitted by the first antenna 21 can be reflected as much as possible, thereby avoiding the radio frequency signals passing through the human head and causing signal attenuation, and thus improving the quality of the communication signals.

[0091] For example, the reflection component 40 can be electrically connected to the control module 30 by FPC, conductive cloth, conductive foam 44, SMT spring, soldered wire, etc., which is not limited here.

[0092] For example, the reflection component 40 can be arranged in the accommodating cavity 10a, or can be arranged on the inner wall of the first shell 10, or can be arranged on the outer wall of the first shell 10, which is not limited. When the reflection component 40 is arranged on the first shell 10, it can be arranged on the second wall surface 102 of the first shell 10, so that it can be close to the human head and effectively reflect the radio frequency signals.

[0093] As shown, Figure 7 In some embodiments, the reflection component 40 comprises a first reflection layer 41, a second reflection layer 42, and a second connecting piece 43. The first reflection layer 41 is arranged on the inner wall of the first shell 10, the second reflection layer 42 is arranged on the outer wall of the first shell 10, and the second connecting piece 43 is configured to pass through the inner wall to the outer wall to connect the first reflection layer 41 and the second reflection layer 42. Arranging the reflection component 40 in two layers can enhance signal reflection, further increase the antenna signal reflection area, reduce the absorption of the human head to the signal, and correspondingly increase the signal radiation intensity. The second reflection layer 42 can be connected to the antenna ground of the control module 30, or can not be connected to the antenna ground of the control module 30. When the influence of the whole machine on radiation is small, the second reflection layer 42 can also not be connected to the antenna ground. Of course, after connecting to the antenna ground, the adaptability to the whole machine environment is stronger, and the reflection effect is better.

[0094] For example, the first reflection layer 41 is arranged on the inner wall of the second wall surface 102, and the second reflection layer 42 is arranged on the outer wall of the second wall surface 102. In this way, the reflection component 40 can be close to the human head and effectively reflect the radio frequency signals.

[0095] For example, the first reflection layer 41 is electrically connected to the control module 30 by the conductive foam 44.

[0096] As shown, Figure 6As shown, in some embodiments, the hanging ear part 100 further comprises a wearing detection circuit board 60, which is electrically connected with the control module 30 and used to detect whether the user wears the smart glasses 1000 by contacting the user's skin. The wearing detection circuit board 60 is arranged on the second wall surface 102 to improve the sensitivity of wearing detection. When the reflection assembly 40 is arranged on the second wall surface 102, the reflection assembly 40 has a second avoiding gap, and the wearing detection circuit board 60 is arranged in the second avoiding gap, so that the wearing detection circuit board 60 and the reflection assembly 40 can be reasonably and compactly arranged in the hanging ear part 100, and the weight and volume of the hanging ear part 100 can be effectively reduced.

[0097] In some embodiments, the reflection assembly 40 is engraved, printed or embedded in the shell wall of the first shell 10. Compared with the pasting way through the double-sided adhesive and the first shell 10, the reflection assembly 40 engraved, printed or embedded in the first shell 10 can make full use of the shape of the hanging ear part 100, effectively reduce the weight and volume of the hanging ear part 100, and reduce the structural risks such as loose fitting and long-term use aging of the reflection assembly 40.

[0098] Exemplarily, the process of engraving the reflection assembly 40 on the shell wall of the first shell 10 can be LDS (Laser Direct Structuring, laser engraving process). Specifically, LDS is to perform laser activation on the surface of the shell wall of the first shell 10 to generate a microscopically rough surface with high adhesion, and then deposit and penetrate the first antenna 21 treated by laser into the surface.

[0099] Exemplarily, the process of printing the reflection assembly 40 on the shell wall of the first shell 10 can be at least one of PDS (Print Direct Structuring, printing forming process) and LRP (Laser Restructuring Printing, laser restructuring printing). Specifically, PDS is a process of printing circuit on the shell wall of the first shell 10 with silver paste, and LRP is to form a three-dimensional circuit shape by three-dimensional printing process, and then to form a high-precision circuit interconnection structure by three-dimensional control laser trimming, by coating conductive silver paste to the surface of the shell wall of the first shell 10 at high speed and high precision.

[0100] Exemplarily, the reflection assembly 40 is embedded in the shell wall of the first shell 10, which can be specifically that an installation groove corresponding to the second antenna 22 is formed on the surface of the shell wall of the first shell 10, and the first antenna 21 is embedded and installed in the installation groove. The embedding can be realized by any suitable way such as clamping and bonding, which is not limited here.

[0101] In some embodiments, the first reflective layer 41 is engraved, printed or embedded on the inner wall of the first shell 10. The specific process can refer to the above description, so that the morphology of the ear part 100 itself can be fully utilized, the weight and volume of the ear part 100 can be effectively reduced, and the structural risks such as loose fitting of the reflective assembly 40 or long-term use aging can be reduced. Illustratively, the first reflective layer 41 is engraved, printed or embedded on the inner wall of the second shell 12.

[0102] In some embodiments, the second reflective layer 42 is engraved, printed or embedded on the outer wall of the first shell 10. The specific process can refer to the above description, so that the morphology of the ear part 100 itself can be fully utilized, the weight and volume of the ear part 100 can be effectively reduced, and the structural risks such as loose fitting of the reflective assembly 40 or long-term use aging can be reduced. Illustratively, the second reflective layer 42 is engraved, printed or embedded on the outer wall of the second shell 12.
