[0041] The earphone 100 provided in the application comprises a shell 10, a sound production assembly 20, a main board 30 and an antenna assembly 40.

[0042] The shell 10 is internally provided with an inner cavity; the sound production assembly 20 is arranged in the inner cavity; the main board 30 is arranged in the inner cavity, and the main board 30 is provided with a feeding portion 31 and a grounding portion 32; the antenna assembly 40 is arranged in the inner cavity, and the antenna assembly 40 comprises a feeding radiating element 41 and at least one grounding radiating element 42, the feeding radiating element 41 is electrically connected with the feeding portion 31 of the main board 30, the grounding radiating element 42 is electrically connected with the grounding portion 32, and the radiation direction of the feeding radiating element 41 is different from the radiation direction of the grounding radiating element 42.

[0043] As shown in Figure 2 and Figure 1 , the shell 10 is a hollow structure, and the inner side of the shell 10 has an inner cavity, and the sound production assembly 20, the main board 30 and the antenna assembly 40 are arranged in the shell 10.

[0044] The feeding radiating element 41 and the grounding radiating element 42 are both metal materials, the feeding portion 31 of the main board 30 is electrically connected with the feeding radiating element 41 so that the electric signal in the main board 30 can be input from the feeding portion 31 into the feeding radiating element 41 and cause electromagnetic oscillation in the feeding radiating element 41 to generate a radio frequency signal, and the grounding portion 32 of the main board 30 is electrically connected with the feeding radiating element 41 so that the electric signal in the main board 30 can be input from the feeding portion 31 into the feeding radiating element 41 and cause electromagnetic oscillation in the feeding radiating element 41 to generate a radio frequency signal.

[0045] In addition, the grounding radiating element 42 is electrically connected with the grounding portion 32 of the main board 30, and when the antenna assembly 40 receives or transmits signals, the grounding radiating element 42, the main board 30 and the feeding radiating element 41 can form a complete current return path, which can eliminate reflection and reduce interference to optimize the radiation performance of the antenna assembly 40.

[0046] The feeding radiating element 41 has its radiation direction, and the radiation direction of the feeding radiating element 41 is the main extension direction of the beam generated by the feeding radiating element 41 after receiving the electric signal input by the feeding portion 31, and in the radiation direction of the feeding radiating element 41, the beam generated by the feeding radiating element 41 has the maximum gain, and the grounding radiating element 42 also has its radiation direction, and the radiation direction of the grounding radiating element 42 is the main extension direction of the beam generated by the grounding radiating element 42 after receiving the electric signal input by the grounding portion 32.

[0047] The radiation direction of the feeding radiating element 41 and the radiation direction of the grounding radiating element 42 have an included angle, that is, the feeding radiating element 41 and the grounding radiating element 42 radiate electromagnetic waves in different directions, so that the antenna beam coverage range of the earphone 100 provided in the application can be improved.

[0048] The earphone 100 provided in the application has the beneficial effect that, compared with the prior art, the earphone 100 provided in the application is connected with the feeding radiating element 41 on the feeding part 31 of the mainboard 30, is connected with the grounding radiating element 42 on the grounding part 32 of the mainboard 30, and the radiation direction of the grounding radiating element 42 has an included angle with the radiation direction of the feeding radiating element 41, on the one hand, the radiation efficiency of the antenna assembly 40 is improved by the combination of the grounding radiating element 42 and the feeding radiating element 41, and on the other hand, the beam coverage range of the antenna assembly 40 is improved by setting the grounding radiating element 42 and the feeding radiating element 41 with different radiation angles, so that the antenna beam coverage range of the earphone 100 provided in the application is improved.

[0049] It can be understood that, due to the reciprocity of the antenna, the feeding radiating element 41 has good radiation performance in its radiation direction, and the feeding radiating element 41 also has good beam receiving performance in its radiation direction, and similarly, the grounding radiating element 42 has good radiation performance in its radiation direction, and the grounding radiating element 42 also has good beam receiving performance in its radiation direction, and in summary, the radiation direction of the feeding radiating element 41 and the radiation direction of the grounding radiating element 42 have an included angle, so that the earphone 100 provided in the application has a wider beam absorption range.

[0050] In some embodiments provided in the application, as shown in Figure 3 , the shell 10 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 are connected in abutment in the first direction x to enclose an inner cavity.

[0051] In some embodiments provided in the application, the grounding radiating element 42 has a plurality of grounding radiating elements 42, and any two grounding radiating elements 42 have different radiation directions.

[0052] As shown in Figure 3 , in the yOz plane shown in Figure 3 , the radiation direction of the feeding radiating element 41 is the a direction shown in Figure 3 , and the radiation directions of the plurality of grounding radiating elements 42 are the b direction, the c direction and the d direction shown in Figure 3 , wherein the a direction is the direction of energy concentration in the beam generated by the feeding radiating element 41, and the b direction, the c direction and the d direction are respectively the directions of energy concentration in the beams generated by the corresponding grounding radiating elements 42.

[0053] In some embodiments, the grounding part 32 has a plurality of grounding parts 32, and the plurality of grounding parts 32 are electrically connected to the plurality of grounding radiating elements 42 in a one-to-one correspondence, and the grounding part 32 is located in the opposite direction of the radiation direction of the corresponding grounding radiating element 42, so that the electrical signal input to the grounding part 32 can generate a beam with the above-mentioned radiation direction in the corresponding grounding radiating element 42.

[0054] In some embodiments, the angle between the radiation direction of each ground radiating element 42 and the radiation direction of the feed radiating element 41 is greater than or equal to 90°.

[0055] Thus, by arranging multiple ground radiating elements 42, the beam coverage of the antenna assembly 40 is increased, and on the other hand, the angle between the radiation direction of the ground radiating element 42 and the radiation direction of the feed radiating element 41 is large, so that the gain of the beam generated by the ground radiating element 42 and the gain of the beam generated by the feed radiating element 41 are uniformly distributed in the yOz plane shown in FIG. 7, further improving the beam coverage of the antenna assembly 40. Figure 2

[0056] In some embodiments provided in the present application, the main plate 30 extends in a plane orthogonal to the first direction x, the feed portion 31 is close to one end of the main plate 30 in the second direction y, and the at least one ground radiating element 42 is located at the other end of the main plate 30 in the second direction y, and the second direction y is orthogonal to the first direction x.

[0057] In some embodiments, as shown in FIG. 7, the main plate 30 extends in the yOz plane shown in FIG. 7, and at least part of the feed radiating element 41 is located on the side of the feed portion 31 away from the ground radiating element 42, so that the current input by the feed portion 31 to the feed radiating element 41 can generate a beam with a radiation direction of the a direction shown in FIG. 7 on the side of the feed portion 31 away from the ground radiating element 42. Figure 4 Figure 4 Figure 3 In some embodiments, as shown in FIG. 7, one ground radiating element 42 is arranged at one end of the main plate 30 away from the feed portion 31 in the second direction y, and at least part of the ground radiating element 42 is located on the side of the ground radiating element 42 away from the feed portion 31, so that the above-mentioned ground radiating element 42 generates a beam with a radiation direction of the b direction shown in FIG. 7. Figure 4 Figure 3

[0058] In some embodiments, as shown in FIG. 7, one ground radiating element 42 is arranged at one end of the main plate 30 away from the feed portion 31 in the second direction y, and at least part of the ground radiating element 42 is located on the side of the ground radiating element 42 away from the feed portion 31, so that the above-mentioned ground radiating element 42 generates a beam with a radiation direction of the b direction shown in FIG. 7. Figure 3 Figure 1 Thus, by arranging the feed portion 31 and the ground radiating element 42 at the two ends of the main plate 30 in the second direction y respectively, the radiation direction of the feed radiating element 41 and the radiation direction of the ground radiating element 42 are arranged in opposite directions along the second direction y, thereby improving the beam coverage of the antenna assembly 40.

[0059] Thus, by arranging the feed portion 31 and the ground radiating element 42 at the two ends of the main plate 30 in the second direction y respectively, the radiation direction of the feed radiating element 41 and the radiation direction of the ground radiating element 42 are arranged in opposite directions along the second direction y, thereby improving the beam coverage of the antenna assembly 40.

[0060] Thus, by arranging the feed portion 31 and the ground radiating element 42 at the two ends of the main plate 30 in the second direction y respectively, the radiation direction of the feed radiating element 41 and the radiation direction of the ground radiating element 42 are arranged in opposite directions along the second direction y, thereby improving the beam coverage of the antenna assembly 40.

[0061] ​​​​​​In some embodiments provided in the present application, the earphone 100 further comprises an ear hook 60, the plurality of ground radiating elements 42 comprises a first radiating element 421, the first radiating element 421 comprises a first connecting portion 4211 and the metal rotating shaft 50, and the end of the shell 10 away from the power feeding portion 31 is connected to the ear hook 60 through the metal rotating shaft 50, and the first connecting portion 4211 is electrically connected between the main board 30 and the metal rotating shaft 50.

[0062] As shown in Figure 7 , the ear hook 60 is rotatably connected to the shell 10 through the metal rotating shaft 50, the ear hook 60 is adapted to be hung above the pinna of the user to fit the shell 10 to the ear canal opening of the user, the metal rotating shaft 50 is made of metal material, the metal rotating shaft 50 is provided with a protruding portion 51, the protruding portion 51 is connected to one end of the first connecting portion 4211 through a screw, and the other end of the first connecting portion 4211 abuts against the elastic contact of the grounding portion 32.

[0063] Therefore, on the one hand, the first radiating element 421 is formed by using the original structure of the earphone 100, thereby reducing the space occupied by the antenna assembly 40 in the inner cavity, and on the other hand, the first connecting portion 4211 is in abutting contact with the grounding portion 32, so that the first connecting portion 4211 is fixedly connected to the metal rotating shaft 50 only, thereby facilitating the assembly between the first connecting portion 4211 and the main board 30.

[0064] In some embodiments, as shown in Figure 3 , a flange 111 is arranged in the shell 10, the flange 111 can press the first connecting portion 4211 against the grounding portion 32 in the first direction x to improve the reliability of the contact between the first connecting portion 4211 and the grounding portion 32, one side of the flange 111 towards the first connecting portion 4211 is provided with a first positioning protrusion, the first connecting portion 4211 is provided with a first positioning hole 4212 penetrating through the first connecting portion 4211 in the first direction x, and the first positioning protrusion can be fitted into the first positioning hole 4212 to position the first connecting portion 4211.

[0065] In some embodiments provided in the present application, at least one ground radiating element 42 is located at one end of the main board 30 in the third direction z, and at least one ground radiating element 42 is located at the other end of the main board 30 in the third direction z, the third direction z is orthogonal to the first direction x, and the third direction z is orthogonal to the second direction y.

[0066] As shown in Figure 3 , one end of the main board 30 in the third direction z is provided with one ground radiating element 42, and the other end of the main board 30 in the third direction z is provided with another ground radiating element 42.

[0067] Therefore, the two ground radiating elements 42 respectively arranged at the two ends of the main board 30 in the third direction z are respectively arranged to Figure 7The c-direction and d-direction radiating beams shown are used to increase the beam coverage of the antenna assembly 40 in the third direction z, thereby improving the communication quality of the antenna assembly 40.

[0068] In some other embodiments, the motherboard 30 has a plurality of grounding radiators 42 at one end in the third direction z, and the motherboard 30 has a plurality of grounding radiators 42 at the other end in the third direction z.

[0069] In some embodiments provided in this application, the plurality of grounding radiating elements 42 include a second radiating element 422. The second radiating element 422 includes a second connecting portion 4221 and a radiating portion 4222. The radiating portion 4222 is attached to the inner wall of the housing 10, and the radiating portion 4222 and the main board 30 are arranged at intervals along the first direction x. The second connecting portion 4221 is disposed at the end of the main board 30 in the third direction z and is connected to the grounding portion 32. The end of the second connecting portion 4221 can abut against the radiating portion 4222 so that the second connecting portion 4221 and the radiating portion 4222 are electrically connected.

[0070] like Figure 10 and Figure 9 As shown, the radiating part 4222 is disposed on the inner wall of the housing 10, and the radiating part 4222 and the main board 30 are arranged at intervals along the first direction x. One end of the second connecting part 4221 is fixedly connected to the main board 30, and the second connecting part 4221 is electrically connected to the grounding part 32. The other end of the second connecting part 4221 extends along the first direction x and can abut against the radiating part 4222, thereby making the radiating part 4222 electrically connected to the grounding part 32 through the second connecting part 4221.

[0071] Thus, the end of the second connecting part 4221 that is close to the radiating part 4222 along the first direction x abuts against the radiating part 4222, which facilitates the assembly of the motherboard 30 and the housing 10 along the first direction x.

[0072] In some embodiments, such as Figure 3 As shown, the second connecting part 4221 and the radiating part 4222 abut against each other at the end of the third direction z near the center of the housing 10, so that the electrical signal of the grounding part 32 is input to the radiating part 4222 from the end of the radiating part 4222 near the center of the housing 10 in the third direction z, so that the radiating part 4222 generates a beam along the third direction z away from the center of the housing 10, thereby making the radiation direction of the second radiating member 422 along the third direction z. Figure 2 The c-direction shown extends as indicated.

[0073] In some embodiments provided in this application, the plurality of grounding radiators 42 include a third radiator 423, one end of which is connected to the end of the motherboard 30 in the third direction z, and the other end of which extends along the edge of the motherboard 30.

[0074] like Figure 3As shown, the third radiator 423 is screwed to the main board 30 at one end in the third direction z near the center of the housing 10, and the other end of the third radiator 423 extends away from the center of the housing 10. This allows the electrical signal from the grounding part 32 to be input to the third radiator 423 from the end of the radiator 4222 in the third direction z near the center of the housing 10, thereby generating a beam along the third direction z away from the center of the housing 10. Figure 2 The d direction shown extends as indicated.

[0075] In some embodiments provided in this application, the housing 10 is provided with a positioning boss 112, and the third radiating element 423 is provided with a positioning groove 4233. The positioning boss 112 can be assembled into the positioning groove 4233 to position the third radiating element 423.

[0076] In some embodiments, such as Figure 2 As shown, the third radiating element 423 also includes a bent section 4231, the bent section 4231 along... Figure 7 As shown, the yOz plane extends, and the bent section 4231 is provided with a second positioning hole 4232 that penetrates the bent section along the first direction x. The housing 10 is provided with a second positioning block 113 that extends along the first direction x. The second positioning block 113 can be assembled into the second positioning hole 4232 along the first direction x.

[0077] Therefore, the third radiating element 423 is positioned by the positioning boss 112 and the second positioning block 113 provided in the housing 10, so as to prevent the third radiating element 423 from shaking in the housing 10.

[0078] When assembling the headphones provided in this application, if Figure 8 As shown, the radiating part 4222 is first machined to be integrated with the housing 10, as follows: Figure 9 As shown, the first connecting part 421 and the metal shaft 50 are machined together as a single unit, such as... Figure 5 As shown, the second connecting part 4221 is machined into one piece with the main board 30, and then the metal rotating shaft 50 is assembled with the housing 10, and the main board 30 is assembled with the housing 10 in sequence.

[0079] In some embodiments provided in this application, the ratio of the sum of the maximum path of the electrical signal input grounding radiator 42 in the motherboard 30 and the maximum path of the electrical signal input feeding radiator 41 in the motherboard 30 to the wavelength of the electrical signal in the motherboard 30 is 0.45-0.55.

[0080] When the motherboard 30 inputs an electrical signal into the power supply radiator 41, the power supply radiator 41-motherboard 30-ground radiator 42 form a complete current loop. The path of the electrical signal from the end of any one of the multiple ground radiators 42 to the end of the power supply radiator 4222 is half the wavelength of the electrical signal.

[0081] Therefore, the resonant frequency of the radiation circuit composed of the feed radiator 41, the main board 30, and the ground radiator 42 is close to the frequency of the electrical signal, which reduces the impedance of the electrical signal when it is conducted in the antenna assembly 40, thereby giving the antenna assembly 40 a higher radiation efficiency.

[0082] In some embodiments provided in this application, the power supply radiator 41 and the sound-generating component 20 are respectively disposed on both sides of the motherboard 30 in the first direction x, and the grounding radiator 42 and the sound-generating component 20 are disposed on the same side of the motherboard 30 in the first direction x.

[0083] like Figure 6 and ​ As shown, the sound-generating component 20 of the earphone 100 provided in this application is located on the side of the motherboard 30 facing the user's ear canal in the first direction x, so as to transmit the sound generated therein to the user's ear canal. The feed radiator 41 is stacked with the motherboard 30 to improve the beam strength of the antenna component 40 on the side away from the user's head in the first direction x. Multiple ground radiators 42 are located on the side of the motherboard 30 facing the user's head in the first direction x, so that the multiple ground radiators 42 can utilize the space around the sound-generating component 20, thereby optimizing the utilization of the space inside the housing 10.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
