Figure 2 Schematic diagram of the electrical connection relationship between the first radiator 41, the second radiator 42, the first phase adjustment module 43 and the first feed source V1 of the first antenna structure 40 in some embodiments of the present application. Figure 1 As shown, the wrist-worn device 100 includes a housing 10, a first pair of ear bodies 20, a first connector 30 and a first antenna structure 40. The first pair of ear bodies 20 are arranged on the periphery of the housing 10 for connecting with a wristband. The first pair of ear bodies 20 include two first ear bodies 21 arranged at intervals. The first connector 30 is connected between the two first ear bodies 21. Figure 1 and Figure 2 As shown, the first antenna structure 40 includes a first radiator 41, a second radiator 42, a first feed source V1 and a first phase adjustment module 43, the first radiator 41 and the second radiator 42 are arranged at an angle, at least a portion of the first radiator 41 is arranged on the first connecting member 30 and includes a first feeding point F1, at least a portion of the second radiator 42 is arranged on one or more of the two first ear bodies 21 and includes a second feeding point F2, the first feed source V1 is used to output a feeding signal, the first phase adjustment module 43 is connected between the first feeding point F1 and the second feeding point F2 and the first feed source V1, and is used to generate two feeding signals with a phase difference of 90° according to the feeding signal output by the first feed source V1, so that the first radiator 41 and the second radiator 42 respectively operate in the first target frequency band under the excitation of the two feeding signals.

[0032] The wrist-worn device 100 provided in the embodiment of the present application can reduce the influence of the PCB (Printed Circuit Board) in the housing 10 on the radiation performance of the first antenna structure 40 by setting the first connector 30 between the two first ear bodies 21 located outside the housing 10, and setting the first radiator 41 and the second radiator 42 on the first connector 30 and the first ear body 21 respectively, and fully utilize the space between the two first ear bodies 21 to set the first radiator 41, which is conducive to the miniaturization and lightweight of the wrist-worn device 100. In addition, since the first radiator 41 and the second radiator 42 are set at an angle, and the phase difference of the radiation current of the first radiator 41 and the second radiator 42 is 90°, the first radiator 41 and the second radiator 42 meet the conditions for forming a circularly polarized or elliptically polarized antenna, and can form a circularly polarized or elliptically polarized antenna, thereby further improving the radiation performance of the first antenna structure 40.

[0033] In some embodiments, the first target frequency band includes a satellite positioning frequency band and / or a satellite communication frequency band.

[0034] The satellite positioning frequency band may include one or more of the Beidou positioning frequency band, the GPS positioning frequency band, the Galileo positioning frequency band, and the GLONASS positioning frequency band. The Beidou positioning frequency band may include one or more of the B1 frequency band (frequency range is approximately 1559.052MHz to 1591.789MHz), the B2 frequency band (frequency range is approximately 1207.140MHz to 1242.390MHz), and the B3 frequency band (frequency range is approximately 1268.520MHz to 1298.170MHz). The GPS positioning frequency band may include one or more of the GPS L1 frequency band (frequency range is approximately 1565.19MHz to 1585.65MHz), the GPS L2 frequency band (frequency range is approximately 1215MHz to 1240MHz), and the GPS L5 frequency band (frequency range is approximately 1166.45MHz to 1186.45MHz). The Galileo positioning frequency band may include one or more of the E1 frequency band (frequency range is approximately 1563.42MHz to 1587.42MHz) and the E5a frequency band (frequency range is approximately 1164MHz to 1188MHz). The GLONASS positioning frequency band may include one or more of the GLONASS L1 frequency band (frequency range is approximately 1598.06MHz to 1609.31MHz) and the GLONASS L2 frequency band (frequency range is approximately 1242.93MHz to 1251.68MHz).

[0035] The satellite communication frequency band may include a Beidou satellite short message communication frequency band, and the Beidou satellite short message communication frequency band includes one or more of a Beidou satellite transmit frequency band (L band, with a frequency range of approximately 1614.26 MHz to 1622.42 MHz) and a Beidou satellite receive frequency band (S band, 2483.59 MHz to 2499.91 MHz).

[0036] The sizes and shapes of the first radiator 41 and the second radiator 42 may be the same or different. The first radiator 41 and the second radiator 42 may be arranged in the same plane or in a non-coplanar manner.

[0037] Among them, since the first phase adjustment module 43 generates two feeding signals with a phase difference of 90° according to the feeding signal output by the first feed source V1, the two feeding signals with a phase difference of 90° are respectively fed into the first radiator 41 and the second radiator 42, which are the radiation currents of the first radiator 41 and the second radiator 42. Therefore, the phase difference of the radiation currents of the first radiator 41 and the second radiator 42 is also 90°.

[0038] The first phase adjustment module 43 may include a coupler, a phase shifter, a π-type matching network, etc.

[0039] The angle between the first radiator 41 and the second radiator 42 may be greater than 0° and less than 180°. In some embodiments, the angle between the first radiator 41 and the second radiator 42 is 90°, which is conducive to the first radiator 41 and the second radiator 42 forming a circularly polarized antenna.

[0040] In some embodiments, the first target frequency band includes a first target sub-frequency band and a second target sub-frequency band that are different from each other. The first sub-target frequency band may include the satellite positioning frequency band and / or the satellite communication frequency band, and the second target sub-frequency band may include the satellite positioning frequency band and / or the satellite communication frequency band.

[0041] See also Figure 3 , is a schematic diagram of the electrical connection relationship between the first radiator 41, the second radiator 42, the first sub-phase adjustment module 431, the second sub-phase adjustment module 432, the first sub-feed source V11 and the second sub-feed source V12 in some embodiments of the present application. Figure 3As shown, the first phase adjustment module 43 includes a first sub-phase adjustment module 431 and a second sub-phase adjustment module 432, and the first feed source V1 includes a first sub-feed source V11 and a second sub-feed source V12. The first sub-phase adjustment module 431 is connected between the first feeding point F1 and the second feeding point F2 and the first sub-feed source V11, and the second sub-phase adjustment module 432 is connected between the first feeding point F1 and the second feeding point F2 and the second sub-feed source V12. The first sub-feed source V11 is used to output a first feed signal, and the first sub-phase adjustment module 431 is used to generate two first sub-feed signals with a phase difference of 90° according to the first feed signal, so that the first radiator 41 and the second radiator 42 respectively work in the first target sub-frequency band under the excitation of the two first sub-feed signals. The second sub-feed source V12 is used to output a second feed signal, and the second sub-phase adjustment module 432 is used to generate two second sub-feed signals with a phase difference of 90° according to the second feed signal, so that the first radiator 41 and the second radiator 42 respectively operate in the second target sub-frequency band under the excitation of the two second sub-feed signals.

[0042] Thus, the first target sub-band and the second target sub-band can share the first radiator 41 and the second radiator 42, which can not only meet the requirements of multi-band communication, but also simplify the first antenna structure 40, which is conducive to the compact design and miniaturization of the wrist-worn device 100. In addition, the first antenna structure 40 is a circularly polarized or elliptically polarized antenna when operating in the first target sub-band and the second target sub-band, so that the communication performance in the two sub-bands is improved.

[0043] In some embodiments, the first target sub-frequency band may be a Beidou satellite receiving frequency band, and the second target sub-frequency band may be a satellite positioning frequency band.

[0044] In some other embodiments, the first target sub-frequency band may be other frequency bands, and the second target sub-frequency band may be other frequency bands.

[0045] See also Figure 1 and Figure 4 , Figure 4 Schematic diagram of the electrical connection relationship between the third radiator 51, the fourth radiator 52, the second phase adjustment module 53 and the second feed source V2 of the second antenna structure 50 in some embodiments of the present application. Figure 1 and Figure 4As shown, the wrist-worn device 100 further includes a second antenna structure 50, the second antenna structure 50 includes a third radiator 51 and a fourth radiator 52 arranged at an angle, and further includes a second feed source V2 and a second phase adjustment module 53, the third radiator 51 includes a third feeding point F3, and the fourth radiator 52 includes a fourth feeding point F4. The second feed source V2 is used to output a feed signal, and the second phase adjustment module 53 is connected between the third feeding point F3 and the fourth feeding point F4 and the second feed source V2, and is used to generate two feed signals with a phase difference of 90° according to the feed signal output by the second feed source V2, so that the third radiator 51 and the fourth radiator 52 respectively work in the second target frequency band under the excitation of the two feed signals, wherein the second target frequency band is different from the first target frequency band.

[0046] Since the third radiator 51 and the fourth radiator 52 are arranged at an angle, and the phase difference between the radiation currents of the third radiator 51 and the fourth radiator 52 is 90°, the third radiator 51 and the fourth radiator 52 meet the formation conditions of a circularly polarized or elliptically polarized antenna, and can form a circularly polarized or elliptically polarized antenna, thereby improving the radiation performance of the second antenna structure 50.

[0047] The second target frequency band may include the aforementioned satellite positioning frequency band and / or satellite communication frequency band, and is different from the first target frequency band. Thus, the wrist-worn device 100 can operate in more satellite communication frequency bands.

[0048] In some embodiments, the second target frequency band may be a Beidou satellite transmission frequency band. In some other embodiments, the second target frequency band may be other frequency bands.

[0049] The sizes and shapes of the third radiator 51 and the fourth radiator 52 may be the same or different. The third radiator 51 and the fourth radiator 52 may be arranged in a coplanar or non-coplanar manner.

[0050] Among them, since the second phase adjustment module 53 generates two feeding signals with a phase difference of 90° according to the feeding signal output by the second feed source V2, the two feeding signals with a phase difference of 90° are respectively fed into the third radiator 51 and the fourth radiator 52, which are the radiation currents of the third radiator 51 and the fourth radiator 52. Therefore, the phase difference of the radiation currents of the third radiator 51 and the fourth radiator 52 is also 90°.

[0051] The second phase adjustment module 53 may include a coupler, a phase shifter, a π-type matching network, etc.

[0052] The angle between the third radiator 51 and the fourth radiator 52 may be greater than 0° and less than 180°. In some embodiments, the angle between the third radiator 51 and the fourth radiator 52 is 90°, which is conducive to the third radiator 51 and the fourth radiator 52 forming a circularly polarized antenna.

Figure 6 FIG. 1 is a schematic diagram of the structure of the wrist-worn device 100 in some other embodiments of the present application. In some embodiments, Figure 1 , Figure 5 and Figure 6 As shown, the wrist-worn device 100 further includes a second pair of ear bodies 60 and a second connecting member 70. The second pair of ear bodies 60 is disposed on the outer periphery of the shell 10 and is spaced apart from the first pair of ear bodies 20. The second pair of ear bodies 60 includes two second ear bodies 61 spaced apart. The second connecting member 70 is connected between the two second ear bodies 61.

[0054] In some embodiments, Figure 5 As shown, at least a portion of the third radiator 51 is disposed on the second connecting member 70, and at least a portion of the fourth radiator 52 is disposed on one or more of the two second ear bodies 61. Thus, the space between the two second ear bodies 61 is fully utilized to dispose the third radiator 51, which is further beneficial to the miniaturization and lightness of the wrist-worn device 100.

[0055] In other embodiments, Figure 6 As shown, at least part of the second radiator 42 is disposed on one first ear body 21, at least part of the fourth radiator 52 is disposed on another first ear body 21, at least part of the first radiator 41 is disposed on the first connecting member 30, and at least part of the third radiator 51 is also disposed on the first connecting member 30. Thus, the space between the two first ear bodies 21 is fully utilized to dispose the third radiator 51, which is further conducive to miniaturization and lightweight of the wrist-worn device 100.

[0058] By providing a first coupling vibrator 44 coupled to the first radiator 41 and a second coupling vibrator 45 coupled to the second radiator 42, the radiation intensity of the first antenna structure 40 can be enhanced and the gain can be improved, thereby effectively improving the performance of the first antenna structure 40 within the first target frequency band.

The first angle and the second angle may be the same or different. In some embodiments, the first angle and the second angle may be angle values ​​within (0°, 15°], or may be angle values ​​within other angle value ranges.

[0062] By arranging the first coupling vibrator 44 and the second coupling vibrator 45 on the first connecting member 30 and the first ear body 21, respectively, the influence of the PCB in the housing 10 on the radiation performance of the first coupling vibrator 44 and the second coupling vibrator 45 can be reduced. In addition, the design space of the first ear body 21 and the first connecting member 30 can also be used to arrange the first coupling vibrator 44 and the second coupling vibrator 45.

In addition, the design space of the first ear body 21 and the first connecting member 30 can also be used to arrange the third coupling vibrator 54 and the fourth coupling vibrator 55.

In some embodiments, as Fig.13 As shown, each second ear body 61 includes a third ear body portion 611 and a fourth ear body portion 612 arranged along the first direction, and the second connecting member 70 includes a third connecting portion 71 and a fourth connecting portion 72 arranged along the first direction, the third connecting portion 71 is connected between the third ear body portions 611 of the two second ear bodies 61, and the fourth connecting portion 72 is connected between the fourth ear body portions 612 of the two second ear bodies 61.

[0074] By arranging the third coupling vibrator 54 and the fourth coupling vibrator 55 at the second ear body 61 and the second connecting member 70, respectively, the influence of the PCB in the housing 10 on the radiation performance of the third coupling vibrator 54 and the fourth coupling vibrator 55 can be reduced. In addition, the design space of the second ear body 61 and the second connecting member 70 can also be used to arrange the third coupling vibrator 54 and the fourth coupling vibrator 55. In addition, by arranging the radiator of the first antenna structure 40 and the radiator of the second antenna structure 50 at the first pair of ear bodies 20 and the second pair of ear bodies 60, respectively, and arranging the coupling vibrator of the first antenna structure 40 and the coupling vibrator of the second antenna structure 50 at the first connecting member 30 and the second connecting member 70, respectively, the first antenna structure 40 and the second antenna structure can have more sufficient design space, which is conducive to optimizing the performance of each of the two antenna structures.

[0075] The third connection portion 71 and the fourth connection portion 72 may be an integrated structure or a split structure. The third connection portion 71 and the fourth connection portion 72 may contact each other or be spaced apart from each other.

[0076] The third ear body portion 611 and the fourth ear body portion 612 may be an integrated structure or a split structure. The third ear body portion 611 and the fourth ear body portion 612 may contact each other or be spaced apart from each other.

[0077] In some embodiments, at least a portion of the first radiator 41 is disposed inside the first connector 30 and is sealed and wrapped by the first connector 30 , and at least a portion of the second radiator 42 is disposed inside the first ear body 21 and is sealed and wrapped by the first ear body 21 .

[0079] Thus, it is possible to avoid at least a portion of the first radiator 41, the second radiator 42, the first coupling vibrator 44, and the second coupling vibrator 45 being exposed, thereby preventing at least a portion of the first radiator 41, the second radiator 42, the first coupling vibrator 44, and the second coupling vibrator 45 from contacting with external substances, which is beneficial to protecting the first radiator 41, the second radiator 42, the first coupling vibrator 44, and the second coupling vibrator 45 and extending their service life. In addition, it is beneficial to provide a larger design space for the appearance of the first connector 30.

[0080] In some embodiments, the first radiator 41, the second radiator 42, the first coupling vibrator 44, and the second coupling vibrator 45 may be LDS (Laser Direct Structuring) or PDS (Printing Direct Structuring) antennas, and at least part of the first radiator 41 and the first coupling vibrator 44 may be molded inside the first connecting portion 31, and at least part of the second radiator 42 and at least part of the second coupling vibrator 45 may be molded inside the first ear body portion 211 by secondary injection molding, so that at least part of the first radiator 41 and at least part of the first coupling vibrator 44 are sealed and wrapped by the first connecting portion 31, and at least part of the second radiator 42 and at least part of the second coupling vibrator 45 are sealed and wrapped by the first ear body portion 211.

[0085] See also Fig.14 and Fig.15 , Fig.14 Schematic diagram of the three-dimensional structure of the wrist-worn device 100 at a viewing angle in some embodiments of the present application. Fig.15 for Fig.14 FIG. 1 is a schematic diagram of a three-dimensional structure of the wrist-worn device 100 at another viewing angle. Fig.14 and Fig.15 As shown, the first connecting member 30 and the second connecting member 70 are both plate-shaped, the shell 10 includes a bottom shell 11 and a side frame 12, the bottom shell 11 is connected to the side frame 12, the two first ear bodies 21 are arranged on the outer periphery of the side frame 12, the first connecting member 30 is inclined relative to the bottom shell 11, and the second connecting member 70 is inclined relative to the bottom shell 11.

[0086] Due to the characteristics of electromagnetic waves, a horizontally polarized signal will generate a polarized current on the surface of the earth when it is close to the ground. The polarized current generates heat energy due to the influence of the earth's impedance, causing the electric field signal to decay rapidly. However, the vertical polarization method is not easy to generate a polarized current. Therefore, when the wrist-worn device 100 is worn on the arm and the arm is placed horizontally relative to the ground, the bottom shell 11 is horizontal relative to the ground, and the first connector 30 and the second connector 70 are both inclined relative to the bottom shell 11. When at least a portion of the first antenna structure 40 is provided on the first connector 30, and at least a portion of the second antenna structure 50 is provided on the second connector 70 or the first connector 30, the electromagnetic waves at least partially emitted by the first antenna structure 40 can have a component in the vertical direction, and the electromagnetic waves at least partially emitted by the second antenna structure 50 can have a component in the vertical direction, thereby reducing the polarized current, avoiding a significant attenuation of energy, and ensuring effective propagation of the signal.

[0087] The side frame 12 is in a ring shape, specifically, it may be, but not limited to, a circular ring shape or a rectangular ring shape.

[0088] In some embodiments, Figure 1 , Figure 5 , Figure 6 and Fig.14As shown, the housing 10 further includes an upper cover 13, and the upper cover 13 includes a display screen, which may be, but is not limited to, an organic light emitting diode (OLED) display screen, a liquid crystal display (LCD) screen, an LED display screen (for example, including a Micro-LED display screen, a Mini-LED display screen), etc. The upper cover 13 is connected to a side of the side frame 12 away from the bottom shell 11. In the correct wearing method, the bottom shell 11 is closer to the arm than the upper cover 13.

[0089] The upper cover 13 , the side frame 12 , and the bottom shell 11 may be, but are not limited to, circular, elliptical, rectangular, or irregular in shape.

[0090] In some embodiments, the first connecting member 30 is connected between the two first ear bodies 21 and connected to the outer periphery of the side frame 12 .

[0091] When at least a portion of the first radiator 41 is disposed inside the first connecting member 30, compared with a gap between the first connecting member 30 and the outer periphery of the side frame 12, since the first connecting member 30 is connected to the outer periphery of the side frame 12, the connection between the first feed source V1 and the first radiator 41 does not need to be connected to the first radiator 41 through a feeder via the first ear body portion 211 or the second ear body portion 212, thereby simplifying the connection path between the first feed source V1 and the first radiator 41.

[0092] When at least part of the third radiator 51 is arranged inside the first connecting member 30, compared with the gap between the first connecting member 30 and the outer periphery of the side frame 12, since the first connecting member 30 is connected to the outer periphery of the side frame 12, the connection between the second feed source V2 and the third radiator 51 does not need to be connected to the third radiator 51 through a feeder via the first ear body portion 211 or the second ear body portion 212, thereby simplifying the connection path between the second feed source V2 and the third radiator 51.

[0093] In some embodiments, the second connector 70 is connected between the two second ear bodies 61 and connected to the outer periphery of the side frame 12, and at least a portion of the third radiator 51 is disposed inside the second connector 70. Thus, the connection between the second feed source V2 and the third radiator 51 does not need to be connected to the third radiator 51 through a feeder line via the third ear body portion 611 or the fourth ear body portion 612, thereby simplifying the connection path between the second feed source V2 and the third radiator 51.

[0094] In some other embodiments, the first connecting member 30 and the second connecting member 70 may also be spaced apart from the side frame 12 , that is, a gap is provided between the first connecting member 30 and the second connecting member 70 and the side frame 12 to separate the first connecting member 30 and the second connecting member 70 from the side frame 12 .

[0095] In some embodiments, the first connecting member 30 is connected to the outer periphery of the first end of the side frame 12 away from the bottom shell 11, and the first connecting member 30 extends from the first end of the side frame 12 in a direction away from the side frame 12 and close to the plane where the bottom shell 11 is located.

[0096] Since the bottom shell 11 is closer to the arm than the upper cover 13 in the correct wearing mode, the first connector 30 is connected to the outer periphery of the first end of the side frame 12 away from the bottom shell 11, and the first connector 30 extends from the first end of the side frame 12 toward the direction away from the side frame 12 and close to the plane where the bottom shell 11 is located, so that the inner contour of the first connector 30 is more matched with the outer contour of the arm, which is convenient for wearing the wrist-worn device 100, and at the same time, it can ensure that the first connector 30 is tilted relative to the bottom shell 11, so that the electromagnetic waves at least partially emitted by the first antenna structure 40 have a component in the vertical direction, and when at least a part of the second antenna structure 50 is arranged on the first connector 30, the electromagnetic waves at least partially emitted by the second antenna structure 50 also have a component in the vertical direction. Thereby, the polarization current is reduced, the significant attenuation of energy is avoided, and the effective propagation of the signal is guaranteed.

[0097] In some embodiments, the second connecting member 70 is connected to the outer periphery of the first end of the side frame 12 away from the bottom case 11, and the second connecting member 70 extends from the first end of the side frame 12 in a direction away from the side frame 12 and close to the plane where the bottom case 11 is located. When at least a portion of the second antenna structure 50 is disposed on the second connecting member 70, the electromagnetic waves at least partially emitted by the second antenna structure 50 also have a component in the vertical direction.

[0098] In some embodiments, Fig.15 As shown, the wrist-worn device 100 further includes a spring ear 80 and a wristband 90 connected to each other, and opposite ends of the spring ear 80 are respectively connected to the two first ear bodies 21. The spring ear 80 includes two, and opposite ends of one of the spring ears 80 are respectively connected to the two first ear bodies 21, and opposite ends of the other spring ear 80 are respectively connected to the two second ear bodies 61.

[0099] See also Fig.16, which is a schematic diagram of the three-dimensional structure of the wrist-worn device 100 in some other embodiments of the present application. In some embodiments, Fig.16 As shown, the first connecting member 30 includes a first connecting plate 33 and a second connecting plate 34 spaced apart, and the second connecting plate 34 is farther away from the bottom shell 11 than the first connecting plate 33, that is, the second connecting plate 34 is closer to the upper cover 13 than the first connecting plate 33. The spring ear 80 is provided between the first connecting plate 33 and the second connecting plate 34, wherein the first connecting plate 33 constitutes the first connecting portion 31, and the second connecting plate 34 constitutes the second connecting portion 32.

[0100] Since the bottom shell 11 is closer to the arm than the upper cover 13 in the correct wearing manner, the raw ear 80 and the portion of the wristband 90 close to the raw ear 80 are both located between the first connecting plate 33 and the arm in the correct wearing manner. Therefore, after being worn, the first connecting plate 33 will cover the raw ear 80 and the portion of the wristband 90 close to the raw ear 80, and the raw ear 80 cannot be seen, making the appearance of the wrist-worn device 100 more concise and beautiful after being worn.

[0101] In some embodiments, the wristband 90 has an axial hole (not shown) in the width direction, the ear 80 is inserted into the axial hole, and the opposite ends of the ear 80 extend out from the axial hole respectively and are rotatably connected to the two first ear bodies 21 respectively, wherein the width direction may be parallel to the arrangement direction of the two first ear bodies 21.

[0102] In some other embodiments, the spring ear 80 may also be exposed. For example, the first connecting plate 33 and the spring ear 80 are arranged side by side in a direction perpendicular to the arrangement direction of the two first ear bodies 21 .

[0103] In some embodiments, the second pair of ear bodies 60 and the first pair of ear bodies 20 may be disposed on opposite sides of the housing 10, that is, the angle between the second pair of ear bodies 60 and the first pair of ear bodies 20 may be 180 degrees. For example, when the wrist-worn device 100 is worn on the user's arm, the arrangement direction of the first pair of ear bodies 20 and the second pair of ear bodies 60 is substantially perpendicular to the length direction of the arm. In other embodiments, the angle between the second pair of ear bodies 60 and the first pair of ear bodies 20 may be less than 180 degrees.

[0104] In some embodiments, the structure of the second pair of ear bodies 60 is the same as that of the first pair of ear bodies 20, and the structure of the second pair of ear bodies 60 is axially symmetrical with that of the first pair of ear bodies 20. For example, when the wrist-worn device 100 is worn on the arm of the user, the first pair of ear bodies 20 and the second pair of ear bodies 60 are symmetrical about the axis of the length direction of the arm. In other embodiments, the structure of the second pair of ear bodies 60 is different from that of the first pair of ear bodies 20.

[0105] In some embodiments, the first connecting member 30 , the second connecting member 70 , the first pair of ear bodies 20 , and the second pair of ear bodies 60 may be made of insulating materials, such as plastic, glass, or ceramic.

[0106] In other embodiments, the first connecting member 30, the second connecting member 70, the first pair of ear bodies 20, and the second pair of ear bodies 60 may be partially made of insulating materials and partially made of conductive materials.

[0107] In some embodiments, the two first ear bodies 21 and the first connecting member 30 may be an integrally formed structure. In other embodiments, the two first ear bodies 21 and the first connecting member 30 may be connected by welding, screwing, riveting, hot pressing, clamping, etc.

[0108] In some embodiments, the two second ear bodies 61 and the second connecting member 70 may be an integrally formed structure. In other embodiments, the two second ear bodies 61 and the second connecting member 70 may be connected by welding, screwing, riveting, hot pressing, clamping, etc.

[0109] In some embodiments, Fig.14 and Fig.15 As shown, the two first ear bodies 21 and the first connector 30 are located at the top side A of the wrist-worn device 100, and the two second ear bodies 61 and the second connector 70 are located at the bottom side B of the wrist-worn device 100, wherein the top side A is the side away from the user when the wrist-worn device 100 is correctly worn by the user, and the bottom side B is the side close to the user when the wrist-worn device 100 is correctly worn by the user. The wrist-worn device 100 being correctly worn by the user may mean that the display screen of the wrist-worn device 100 is oriented in the same direction as the back of the hand on which it is worn, and when viewed by the user, the screen of the wrist-worn device 100 displays a picture that is in upright position.

[0110] Furthermore, at least parts of the first radiator 41 and the third radiator 51 are respectively arranged on the first ear body parts 211 of the two first ear bodies 21, at least parts of the first coupling vibrator 44 and the third coupling vibrator 54 are arranged on the second ear body parts 212 of the two first ear bodies 21, at least parts of the second radiator 42 and the fourth radiator 52 are both arranged on the first connecting part 31, and at least parts of the second coupling vibrator 45 and the fourth coupling vibrator 55 are both arranged on the second connecting part 32, that is, the above-mentioned radiators and coupling vibrators are all arranged on the top side A of the wrist-worn device 100, so that when the wearer puts the wrist-worn device 100 close to the ear for a call, the first antenna structure 40 and the second antenna structure 50 can be avoided from being blocked by the ear, head and other parts, thereby making the communication smoother.

[0111] In some embodiments, the first connection portion 31 is closer to the bottom shell 11 than the second connection portion 32, and the first ear body portion 211 is closer to the bottom shell 11 than the second ear body portion 212. In other embodiments, the first connection portion 31 is farther from the bottom shell 11 than the second connection portion 32, and the first ear body portion 211 is farther from the bottom shell 11 than the second ear body portion 212.

[0112] In some embodiments, the third connection portion 71 is closer to the bottom shell 11 than the fourth connection portion 72, and the third ear body portion 611 is closer to the bottom shell 11 than the fourth ear body portion 612. In other embodiments, the third connection portion 71 is farther from the bottom shell 11 than the fourth connection portion 72, and the third ear body portion 611 is farther from the bottom shell 11 than the fourth ear body portion 612.

[0113] See also Fig.17 , is a schematic diagram of the electrical connection relationship of some components of the wrist-worn device 100 in some embodiments of the present application. Fig.17 As shown, the wrist-worn device 100 may also include a circuit board 110, a radio frequency front end module (RFFEM) 120, a radio frequency integrated circuit (RFIC) 130, and a baseband processor 140, etc. The RF front end module 120, the RF integrated circuit 130, and the baseband processor 140 may all be arranged on the circuit board 110. The first feed source V1 is also connected to the RF front end module 120. When the wrist-worn device 100 includes the second feed source V2, the second feed source V2 is also connected to the RF front end module 120.

[0114] Exemplarily, in a receiving scenario, the first antenna structure 40 can receive electromagnetic waves, convert the electromagnetic waves into electrical signals and transmit them to the first feed source V1, and through the RF front-end module 120 connected to the first feed source V1, switch to the corresponding receiving link through a device with a switching function in the RF front-end module 120, amplify, filter, mix and other processes the RF signal through the receiving link, and then send the RF signal to the RF integrated circuit 130, the RF integrated circuit 130 processes the RF signal into a baseband modulated signal, and transmits the baseband modulated signal to the baseband processor 140, the baseband processor 140 converts the baseband modulated signal into a baseband signal, and determines the information carried in the electromagnetic wave after converting the baseband signal into data.

[0115] The bottom shell 11, the side frame 12 and the upper cover 13 are arranged to form a containing cavity (not shown in the figure), and the first feed source V1, the second feed source V2, the circuit board 110, the RF front-end module 120, the RF integrated circuit 130 and the baseband processor 140 can all be arranged in the containing cavity.

[0116] See also Figure 6 and Fig.18 , Fig.18 FIG. 1 is a schematic diagram of the structure of the wrist-worn device 100 in some other embodiments of the present application. Figure 6 and Fig.18 As shown, the wrist-worn device 100 further includes a third antenna structure 95. At least a portion of the third antenna structure 95 is disposed on the second connector 70, wherein the third antenna structure 95 supports the Sub 1G frequency band.

[0117] By arranging at least a portion of the third antenna structure 95 on the second connector 70, that is, at least a portion of the third antenna structure 95 is located outside the housing 10, the influence of the PCB located in the housing 10 on the radiation efficiency of the third antenna structure 95 can be reduced. In addition, since the third antenna structure 95 needs to support the Sub 1G frequency band, the required size of the third antenna structure 95 is often longer. By arranging at least a portion of the third antenna structure 95 on the second connector 70, the setting requirements of the third antenna structure 95 with a longer size can be met, and the occupation of the internal space of the wrist-worn device 100 by the third antenna structure 95 can be effectively reduced. In addition, by arranging at least a portion of the third antenna structure 95 on the second connector 70, the space of the second connector 70 can be fully utilized.

[0118] The frequency range of the Sub 1G frequency band is 100 MHz to 1 GHz.

[0119] In some embodiments, the Sub 1G frequency band may be a 400 MHz frequency band, and the third antenna structure 95 is used to support short-range communication in the 400 MHz frequency band, where the short-range communication is communication with a communication distance less than or equal to 5 kilometers.

[0120] Thus, the wrist-worn device 100 can realize wireless communication with other electronic devices within a range of less than or equal to 5 kilometers without the need for cellular communication, which facilitates applications in some scenarios. For example, in remote areas where the cellular communication signal is poor, wireless communication can be carried out with other electronic devices through the small-range communication in the 400MHz frequency band supported by the third antenna structure 95 in the embodiment of the present application, thereby ensuring the reliability of the communication connection.

[0121] In some embodiments, the 400 MHz frequency band may be a frequency band corresponding to a certain frequency range with a resonance frequency of 400 MHz, for example, a frequency band corresponding to a frequency range of 300 MHz to 500 MHz with a resonance frequency of 400 MHz.

[0122] In some other embodiments, the third antenna structure 95 may also support other frequency bands in the Sub 1G frequency band, or may support communications in other frequency bands outside the Sub 1G frequency band, and is not limited to the examples in the embodiments of the present application.

[0123] In some embodiments, part of the third antenna structure 95 is disposed on the second connecting member 70 , and the remaining part is disposed on one or more of the two second ear bodies 61 , and the remaining part may also be disposed on the shell 10 .

[0124] For example, Figure 6 and Fig.18 As shown, the third antenna structure 95 includes a first radiation section 951 and a second radiation section 952 , wherein the first radiation section 951 is disposed on a second ear body 61 , and the second radiation section is disposed on the second connecting member 70 .

[0125] In some other embodiments, the entire third antenna structure 95 is disposed on the second connecting member 70 .

[0126] In some embodiments, at least a portion of the three-antenna structure 95 is disposed inside the second connector 70 and is sealed and wrapped by the second connector 70 .

[0127] The third antenna structure 95 may be an LDS (Laser Direct Structuring) or PDS (Printing Direct Structuring) antenna.

[0128] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0129] The above is an implementation method of the embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
