Description
Technical Field
[0001] This application relates to the field of headphone technology, and in particular to a wireless headphone and electronic device. Background Technology
[0002] With the development of electronic devices, their audio-visual entertainment functions have become increasingly sophisticated, leading to the rapid growth of headphone products. Among them, wireless headphones, due to their lack of wires, are particularly popular with consumers.
[0003] However, due to form factor limitations and the requirement for thin and light design, wireless headphones have a very compact internal architecture. This results in the antenna components being close to the battery, PCB (Printed Circuit Board), and other components, limiting the antenna clearance and thus leading to poor wireless transmission performance. Utility Model Content
[0004] This application provides a wireless headset and electronic device that can solve the problem of poor wireless transmission performance caused by limited clearance of antenna components.
[0005] The technical solution is as follows:
[0006] On one hand, a wireless earphone is provided, the wireless earphone comprising: a housing assembly, a speaker assembly, and a radiating assembly;
[0007] The loudspeaker assembly includes a loudspeaker body and loudspeaker circuitry, and the radiating assembly includes a radiating antenna.
[0008] The speaker body is located inside the housing assembly, and the radiating antenna is located on the inner wall of the housing assembly surrounding the speaker body;
[0009] The speaker circuit includes at least one decoupling module, which is connected in series with the signal terminals of the speaker body.
[0010] In this embodiment of the wireless earphone, in order to solve the problem of poor clearance of the radiating antenna, the radiating antenna is arranged on the inner wall of the housing assembly around the speaker body, and a decoupling module is connected in series on the signal terminal of the speaker body. Even if the distance between the radiating antenna and the speaker body is close, the speaker body will not interfere with the radiating antenna under the action of the decoupling module, thereby improving the wireless communication effect of the wireless earphone.
[0011] In some possible implementations, the housing assembly includes a first housing and a second housing, which are fastened together.
[0012] The first housing has a sound outlet and is located on the front side of the speaker body, while the second housing is located on the rear side of the speaker body;
[0013] The radiating antenna is located on the inner wall of the second housing.
[0014] In this embodiment, the radiating antenna is arranged on the inner wall of the second housing, which can make full use of the inner wall space of the second housing and reduce the difficulty of radiating antenna arrangement.
[0015] In some possible implementations, the second housing includes a back shell portion and a first side enclosure portion, the back shell portion being located at the rear side of the speaker body, and the first side enclosure portion being located at the circumferential edge of the back shell portion;
[0016] At least a portion of the radiating antenna is located on the inner wall of the back shell portion, and another portion is located on the inner wall of the first side enclosure portion.
[0017] Since the speaker body can be decoupled using a decoupling module, other components in the wireless earphone may still interfere with the radiating antenna. Therefore, this embodiment can make full use of the inner wall of the first side enclosure around the speaker body, so that the radiating antenna can maximize the net space distance between itself and other components outside the speaker body, thus ensuring the radiation performance of the radiating antenna.
[0018] In some possible implementations, the distance between the radiating antenna and the speaker body is greater than or equal to 1 mm;
[0019] And / or, the radiating antenna is a planar inverted F-shaped antenna.
[0020] With the above arrangement, the radiating antenna can meet the wireless communication requirements of the wireless headphones.
[0021] In some possible implementations, the wireless earphones further include a circuit board assembly located within the housing assembly;
[0022] The speaker circuit is located on the circuit board assembly;
[0023] The radiating component is provided with a power supply circuit and a grounding circuit. The power supply circuit and the grounding circuit are respectively located on the circuit board assembly and are electrically connected to the radiating antenna.
[0024] With the above arrangement, the radiating antenna can be fed and grounded using the feeding circuit and grounding circuit, thus meeting the operational requirements of the radiating antenna.
[0025] In some possible implementations, the signal terminal includes a positive terminal and a negative terminal;
[0026] The decoupling module comprises two components, each including an LC band-stop filter. One LC band-stop filter is connected in series with the positive terminal, and the other LC band-stop filter is connected in series with the negative terminal.
[0027] With the above arrangement, using an LC band-stop filter as the decoupling module results in a simpler and more compact structure, which can meet the board layout and space constraints of the wireless earphone circuit board components.
[0028] In some possible implementations, the LC bandstop filter includes an inductor and a capacitor connected in parallel, wherein the inductor has an inductance of 8.5 nH and the capacitor has a capacitance of 0.5 pF.
[0029] With the above arrangement, the LC band-stop filter can generate an equivalent impedance of approximately 700 ohms, and the 8.5nH inductor has less impact on the audio signal of the speaker body, effectively solving the interference of the speaker body's signal on the antenna performance, improving the antenna performance by approximately 2dB.
[0030] In some possible implementations, the circuit board assembly includes a power feed spring and a ground spring. The bottom of the power feed spring is soldered to the power feed circuit, the top of which faces the inner wall of the back shell and abuts against the radiating antenna on the back shell. The bottom of the ground spring is soldered to the ground circuit, the top of which faces the inner wall of the back shell and abuts against the radiating antenna on the back shell.
[0031] With the above arrangement, the power supply circuit and grounding circuit on the circuit board assembly can be connected to the radiating antenna through the power supply spring and grounding spring, respectively. The structure is simple and helps to reduce the difficulty of power supply and grounding of the radiating antenna.
[0032] In some possible implementations, the circuit board assembly includes a circuit board body arranged axially perpendicular to the speaker body;
[0033] The circuit board body has a notch at one end facing the speaker body, and at least a portion of the speaker body is located within the notch; two protrusions are respectively provided at both ends of the notch.
[0034] The speaker circuit includes a first pad and a second pad, the first pad and the second pad are located on one of the protrusions, and the signal terminals are soldered to the first pad and the second pad respectively;
[0035] At least one of the power feed spring and the grounding spring is located on the other protrusion.
[0036] With the above arrangement, the speaker body is housed within the notch of the circuit board body, thereby improving the structural compactness of both the circuit board body and the speaker body. Furthermore, by fully utilizing the protrusions on both sides of the notch, one protrusion is used to arrange the first and second pads of the speaker circuit, allowing for close connection to the signal terminals of the speaker body and reducing the difficulty of connecting the speaker body. The other protrusion is used to arrange the grounding spring and the feeding spring, enabling feeding and grounding of the radiating antenna around the speaker body.
[0037] In some possible implementations, the radiating antenna includes a first radiating part, a second radiating part, and a feed grounding part;
[0038] The first radiating part and the second radiating part are respectively located on opposite sides of the power supply grounding part;
[0039] The first radiating part is located on the inner wall of the first side panel corresponding to the speaker body, and the second radiating part is located on the inner wall of the first side panel corresponding to the circuit board assembly;
[0040] The power supply spring and the grounding spring respectively come into contact with the power supply grounding part.
[0041] With the above arrangement, the radiating antenna has two radiating parts, a first radiating part and a second radiating part, which can be used for different frequency bands of radiation, thereby improving the coverage range of the radiating antenna and enhancing the wireless communication performance of the wireless headset.
[0042] On the other hand, an electronic device is provided, comprising: the wireless earphone described in this application, and a terminal device; the terminal device is communicatively connected to the wireless earphone via the radiating antenna.

[0066] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.
[0067] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0068] On the one hand, combined with Figures 1 to 5 As shown, this embodiment provides a wireless earphone, which includes: a housing assembly 1, a speaker assembly 2, and a radiating assembly 3.
[0069] The speaker assembly 2 includes a speaker body 21 and a speaker circuit 22, and the radiating assembly 3 includes a radiating antenna 31; the speaker body 21 is located inside the housing assembly 1, and the radiating antenna 31 is located on the inner wall of the housing assembly 1 surrounding the speaker body 21.
[0070] The speaker circuit 22 includes at least one decoupling module 221, which is connected in series with the signal terminal 211 of the speaker body 21.
[0071] In this embodiment of the wireless earphone, in order to solve the problem of poor clearance of the radiating antenna 31, the radiating antenna 31 is arranged on the inner wall of the housing assembly 1 around the speaker body 21, and a decoupling module 221 is connected in series on the signal terminal 211 of the speaker body 21. Even if the distance between the radiating antenna 31 and the speaker body 21 is close, the speaker body 21 will not interfere with the radiating antenna 31 under the action of the decoupling module 221, thereby improving the wireless communication effect of the wireless earphone.
[0072] In some possible implementations, the radiating antenna 31 is at least one of an FPC antenna and an LDS antenna.
[0073] In some other possible implementations, the radiating antenna 31 is a Bluetooth antenna capable of covering the 2.4-2.5 GHz frequency band. Exemplarily, the decoupling module 221 is used to prevent the speaker body 21 from generating 2.4-2.5 GHz frequency band signals that could interfere with the performance of the radiating antenna 31.
[0074] In some possible implementations, the wireless earphones consist of an earphone body, ear hooks, and a battery case. A housing assembly 1 at least encloses the earphone body, while a speaker assembly 2 and a radiating assembly 3 are located within the earphone body. Exemplarily, the ear hook has an arc-shaped structure, with the earphone body and battery case connected to its two ends. The ear hook can be hung on the ear, with the earphone body located in front of the ear and the battery case located behind the ear. Exemplarily, the wireless earphones are open-back earphones.
[0075] Combination Figure 3 and Figure 5 As shown, in some possible implementations, the housing assembly 1 includes a first housing 11 and a second housing 12, which are fastened together; the first housing 11 is provided with a sound outlet 111 and is located on the front side of the speaker body 21, and the second housing 12 is located on the rear side of the speaker body 21; the radiating antenna 31 is located on the inner wall of the second housing 12.
[0076] In this embodiment, the radiating antenna 31 is arranged on the inner wall of the second housing 12, which can make full use of the inner wall space of the second housing 12 and reduce the difficulty of arranging the radiating antenna 31.
[0077] Combination Figure 4 and Figure 5 As shown, in some possible implementations, the second housing 12 includes a back shell portion 121 and a first side enclosure portion 122. The back shell portion 121 is located on the rear side of the speaker body 21, and the first side enclosure portion 122 is located on the circumferential edge of the back shell portion 121.
[0078] At least a portion of the radiating antenna 31 is located on the inner wall of the back shell portion 121, and another portion is located on the inner wall of the first side portion 122.
[0079] Since the speaker body 21 can be decoupled by the decoupling module 221, other components in the wireless earphone may still interfere with the radiating antenna 31. Therefore, this embodiment can make full use of the inner wall of the first side enclosure 122 around the speaker body 21, so that the radiating antenna 31 can maximize the net space distance between itself and other components outside the speaker body 21, thus ensuring the radiation performance of the radiating antenna 31.
[0080] In some possible implementations, the distance between the radiating antenna 31 and the speaker body 21 is greater than or equal to 1 mm; and / or, the radiating antenna 31 is a planar inverted F-shaped antenna.
[0081] With the above arrangement, the radiating antenna 31 can meet the wireless communication requirements of the wireless headphones.
[0082] Combination Figure 2 and Figure 5 As shown, in some possible implementations, the wireless earphone also includes a circuit board assembly 4, which is located inside the housing assembly 1.
[0083] The loudspeaker circuit 22 is located on the circuit board assembly 4; the radiating assembly 3 is provided with a power supply circuit 32 and a grounding circuit 33, which are located on the circuit board assembly 4 and electrically connected to the radiating antenna 31 respectively.
[0084] With the above arrangement, the radiating antenna 31 can be fed and grounded by the feeding circuit 32 and the grounding circuit 33, thus meeting the working requirements of the radiating antenna 31.
[0085] For example, the power supply circuit 32 and the grounding circuit 33 are respectively plated circuit structures on the circuit board assembly 4.
[0086] Combination Figure 6 As shown, in some possible implementations, signal terminal 211 includes a positive terminal 2111 and a negative terminal 2112; there are two decoupling modules 221, each of which includes an LC band-stop filter, one of which is connected in series with the positive terminal 2111, and the other is connected in series with the negative terminal 2112.
[0087] With the above arrangement, using an LC band-stop filter as the decoupling module 221 results in a simpler and more compact structure, which can meet the board layout and space constraints of the wireless earphone circuit board assembly 4.
[0088] In some possible implementations, the LC bandstop filter includes an inductor 221L and a capacitor 221C connected in parallel, with the inductor 221L having an inductance of 8.5nH and the capacitor 221C having a capacitance of 0.5pF.
[0089] With the above arrangement, the LC band-stop filter can generate an equivalent impedance of approximately 700 ohms, and the 8.5nH inductor 221L has less impact on the audio signal of the speaker body 21, effectively solving the interference of the speaker body 21 signal on the antenna performance, and improving the antenna performance by approximately 2dB.
[0090] refer to Figure 7 As shown, in the Bluetooth band, the wireless headphones can achieve a radiation efficiency (Radio Efficiency), system Rad Efficiency (System Rad Efficiency), and system Total Efficiency (System Total Efficiency) of -9.2dB, demonstrating good radiation performance.
[0091] In addition, combined Figure 8 and Figure 9 The antenna pattern diagram and simulation diagram shown demonstrate that the antenna pattern of the wireless headset meets normal communication requirements.
[0092] Combination Figure 2 and Figure 5 As shown, in some possible implementations, the circuit board assembly 4 includes a power feed spring 41 and a ground spring 42. The bottom of the power feed spring 41 is soldered to the power feed circuit 32, the top faces the inner wall of the back shell 121, and abuts against the radiating antenna 31 on the back shell 121. The bottom of the ground spring 42 is soldered to the grounding circuit 33, the top faces the inner wall of the back shell 121, and abuts against the radiating antenna 31 on the back shell 121.
[0093] With the above arrangement, the power supply circuit 32 and the grounding circuit 33 on the circuit board assembly 4 can be connected to the radiating antenna 31 by the power supply spring 41 and the grounding spring 42 respectively. The structure is simple and helps to reduce the difficulty of power supply and grounding of the radiating antenna 31.
[0094] Combination Figure 5 As shown, in some possible implementations, the circuit board assembly 4 includes a circuit board body 43, which is arranged axially perpendicular to the speaker body 21.
[0095] The circuit board body 43 has a notch 431 at one end facing the speaker body 21, and at least a portion of the speaker body 21 is located in the notch 431; two protrusions 432 are respectively provided at both ends of the notch 431; the speaker circuit 22 includes a first pad 222 and a second pad 223, the first pad 222 and the second pad 223 are located on one of the protrusions 432, and the signal terminal 211 is soldered to the first pad 222 and the second pad 223 respectively; at least one of the power feed spring 41 and the ground spring 42 is located on the other protrusion 432.
[0096] With the above arrangement, the speaker body 21 is housed within the notch 431 of the circuit board body 43, thereby improving the structural compactness of the circuit board body 43 and the speaker body 21. Furthermore, by fully utilizing the protrusions 432 on both sides of the notch 431, one protrusion 432 is used to arrange the first pad 222 and the second pad 223 of the speaker circuit 22, allowing for close connection to the signal terminals 211 of the speaker body 21, reducing the connection difficulty of the speaker body 21. The other protrusion 432 is used to arrange the grounding spring 42 and the feeding spring 41, enabling power feeding and grounding of the radiating antenna 31 surrounding the speaker body 21.
[0097] Combination Figure 4 As shown, in some possible implementations, the radiating antenna 31 includes a first radiating part 311, a second radiating part 312, and a feed grounding part 313.
[0098] The first radiating part 311 and the second radiating part 312 are located on opposite sides of the power supply grounding part 313, respectively; the first radiating part 311 is located on the inner wall of the first side enclosure 122 corresponding to the speaker body 21, and the second radiating part 312 is located on the inner wall of the first side enclosure 122 corresponding to the circuit board assembly 4; the power supply spring 41 and the grounding spring 42 are in contact with the power supply grounding part 313, respectively.
