In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 As shown, the utility model provides an antenna assembly 100 , which includes a mainboard 110 and an antenna 120 .

[0037] The main board 110 is a circuit board, and has a first board surface and a second board surface opposite to the first board surface. The first board surface is provided with a signal output terminal, a first ground connection terminal and a second ground connection terminal.

[0038] The antenna 120 includes a first part 121 and a second part 122, both of which are located on a side of the mainboard 110 away from the second board surface, and the first part 121 and the second part 122 are spaced apart, the first part 121 is connected to a feeding part 1211 and a first grounding part 1212, the second part 122 is connected to a second grounding part 1221, the feeding part 1211 is connected to a signal output end, the first grounding part 1212 is connected to a first grounding connection end, and the second grounding part 1221 is connected to a second grounding connection end.

[0039] It can be understood that the first part 121 and the second part 122 of the antenna 120 are both located on the same side of the mainboard 110 and are close to the first board surface of the mainboard 110; the feeding part 1211 of the first part 121 is connected to the signal output end for receiving the radio frequency signal, and the first grounding part 1212 is connected to the first grounding connection end for grounding; the second grounding part 1221 of the second part 122 is connected to the second grounding connection end for grounding.

[0040] It should be noted that the first portion 121 and the second portion 122 are coupled to each other.

[0041] It can be understood that when the antenna assembly 100 of the present invention is working, the signal output end of the mainboard 110 outputs a radio frequency signal to the first part 121 through the feeding part 1211, so that the first part 121 of the antenna 120 can transmit and receive signals in the first frequency band; the second part 122 is coupled to the first part 121, and under the coupling effect, the second part 122 can transmit and receive signals in the second frequency band. In this way, the antenna assembly 100 of the present invention can realize the transmission and reception functions of signals in two different frequency bands.

[0042] It should be noted that the first frequency band may be a signal in the 2.4 GHz frequency band, and the second frequency band may be a signal in the 5 GHz frequency band.

[0043] It can be understood that by changing the length of the first part 121 and / or the second part 122, the transmission and reception of signals in the other two frequency bands can be achieved.

[0044] It should be noted that, in the antenna assembly 100 of the present invention, on the one hand, the first part 121 and the second part 122 of the antenna 120 are arranged on the same side of the mainboard 110, which can reduce the space occupied by the antenna 120 in the direction perpendicular to the mainboard 110, compared with the case where the first part 121 and the second part 122 of the antenna 120 are arranged on both sides of the mainboard 110 respectively; on the other hand, the antenna assembly 100 of the present invention uses coupling to realize the transmission and reception of the second frequency band signal, and the second part 122 does not need to be connected to other signal output terminals, so other signal output terminals do not need to be arranged on the mainboard 110, which can save the space of the mainboard 110. In addition, in the antenna assembly 100 of the present invention, since the second part 122 is coupled with the first part 121 to transmit and receive signals, the first part 121 and the second part 122 can be arranged more compactly to reduce the occupied space.

[0045] It should be noted that the material of the first portion 121 and the second portion 122 of the antenna 120 may be, but is not limited to, conductive materials such as copper and silver.

[0046] It is understandable that the first portion 121 and the second portion 122 of the antenna 120 are spaced apart in a direction parallel to the first board surface, so that the space occupied by the antenna 120 in a direction perpendicular to the mainboard 110 can be reduced.

[0047] like Figure 2 As shown, in some embodiments, the first portion 121 has a first end 121a and a second end 121b, the second portion 122 has a third end 122a and a fourth end 122b, the first end 121a is opposite to the third end 122a and is spaced apart, the first portion 121 extends in an arc shape from the first end 121a along a first direction to the second end 121b, the second portion 122 extends in an arc shape from the third end 122a along a second direction to the fourth end 122b, and the fourth end 122b is opposite to the second end 121b and is spaced apart.

[0048] It should be noted that the first direction is Figure 2 The second direction is counterclockwise. Figure 2In the clockwise direction of the antenna 200, the first direction and the second direction are opposite directions. According to the above-mentioned arrangement of the first part 121 and the second part 122, the overall contour of the first part 121 and the second part 122 is approximately a non-closed circle, which can be easily installed in the cylindrical middle shell 200. In addition, the overall contour of the first part 121 and the second part 122 is approximately a non-closed circle, which can reduce the space occupied by the antenna 120 in the direction parallel to the first board surface compared to the linear first part 121 and the second part 122.

[0049] In some embodiments, the feeding portion 1211 and the first grounding portion 1212 are both connected to the side of the first portion 121, the feeding portion 1211 is located on the side of the first grounding portion 1212 close to the first end 121a of the first portion 121, and the second grounding portion 1221 is connected to the third end 122a of the second portion 122.

[0050] It is understandable that by arranging the feeding portion 1211 on the side of the first grounding portion 1212 close to the first end 121a of the first portion 121, that is, the feeding portion 1211 can be closer to the first end 121a in the first portion 121, which is helpful to reduce the length of the first portion 121.

[0051] It can be understood that the effective length of the first part 121 is: the length from the feeding part 1211 to the farthest distance from the feeding part 1211. Thus, in order to make the effective length of the first part 121 reach the set value, by making the feeding part 1211 closer to the first end 121a in the first part 121, it is helpful to reduce the length setting of the entire first part 121, thereby reducing the occupied space.

[0052] like Figure 1 As shown, in some embodiments, a first spring clip 111 electrically connected to the signal output end, a second spring clip 112 electrically connected to the first ground connection end, and a third spring clip 113 electrically connected to the second ground connection end are provided on the first board surface, the feeding part 1211 is connected to the first spring clip 111, the first grounding part 1212 is connected to the second spring clip 112, and the second grounding part 1221 is connected to the third spring clip 113.

[0053] It should be noted that the first spring piece 111 , the second spring piece 112 , and the third spring piece 113 are all made of conductive materials, such as pure copper, pure silver, or conductive alloy.

[0054] like Figure 3As shown, it should be noted that an antenna circuit is provided on the mainboard 110, and the antenna circuit includes a first wireless chip and a second wireless chip connected in parallel, the first wireless chip is used to generate a signal in a first frequency band, and the second wireless chip is used to generate a signal in a second frequency band; the antenna circuit also includes a radio frequency switch, a filter and a matching network connected in series in sequence, the first wireless chip and the second wireless chip are respectively connected to the radio frequency switch, and the matching network is connected to the antenna.

[0055] It can be understood that the RF switch connects the first wireless chip and the second wireless chip back and forth at a time interval of microseconds, so that the first wireless chip and the second wireless chip work at intervals of microseconds; however, since the time interval between the first wireless chip and the second wireless chip is too small, from a macro perspective, the antenna assembly 100 can simultaneously transmit and receive signals in the first frequency band and the second frequency band.

[0056] Specifically in this embodiment, the first wireless chip is a 2.4G wireless chip, and the second wireless chip is a 5G wireless chip.

[0057] It should be noted that, compared with using two sets of circuits to realize the transmission and reception of signals by two different antennas, the above antenna circuit simplifies the circuit design, saves components and also saves the space occupied by the circuit board.

[0058] Combination Figure 1 , Figure 4 and Figure 5 The utility model also provides an electronic device, comprising the antenna assembly 100 as described above.

[0059] Among them, electronic devices can be products such as headphones, watches, mobile phones, computers or electronic glasses.

[0060] The electronic device of the utility model has the above-mentioned antenna assembly 100. In the antenna assembly 100, on the one hand, the first part 121 and the second part 122 of the antenna 120 are arranged on the same side of the mainboard 110. Compared with the first part 121 and the second part 122 of the antenna 120 being arranged on both sides of the mainboard 110 respectively, the space occupied by the antenna 120 in the direction perpendicular to the mainboard 110 can be reduced; on the other hand, the antenna assembly 100 of the utility model uses coupling to realize the transmission and reception of the second frequency band signal, and the second part 122 does not need to be connected to other signal output terminals. Therefore, other signal output terminals do not need to be arranged on the mainboard 110, which can save the space of the mainboard 110. In addition, in the antenna assembly 100 of the utility model, since the second part 122 is coupled with the first part 121 to transmit and receive signals, the first part 121 and the second part 122 can be arranged more compactly to reduce the occupied space. In this way, it is conducive to the miniaturization design of the electronic device.

[0061] Specifically in this embodiment, the electronic device is a TWS headset, which includes a middle shell 200 , in which the antenna assembly 100 is disposed, and an axis of the antenna assembly 100 is parallel to an axis of the middle shell 200 .

[0062] Furthermore, the TWS earphone also includes an upper cover assembly 300 arranged on the middle shell 200, and the upper cover assembly 300 covers the top opening of the middle shell 200. The interior of the upper cover assembly 300 is provided with a first pressing member 310, a second pressing member 320 and a third pressing member 330. The first pressing member 310 is used to press the feeding part 1211, the second pressing member 320 is used to press the first grounding part 1212, and the third pressing member 330 is used to press the second grounding part 1221, so that the feeding part 1211, the first grounding part 1212 and the second grounding part 1221 are in good contact with the first spring piece 111, the second spring piece 112 and the third spring piece 113 respectively.

[0063] It should be noted that the TWS earphone also includes a lower shell component 400 connected to the lower end of the middle shell 200, and an earplug 500 connected to the lower shell component 400.

[0064] It can be understood that TWS headphones are smart headphones, and TWS headphones can be configured with call noise reduction function and / or artificial intelligence noise reduction function, and can also be configured with stereo surround and other functions.

[0065] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
