[0023] See also Figure 1 and Figure 2 The earphone 1 may include a housing 10 and an antenna assembly 20. The antenna assembly 20 may be disposed in the housing 10 for transmitting and receiving signals so that the earphone 1 can wirelessly communicate with an external device.

[0024] Taking the headset 1 as a wireless headset as an example, it generally includes a radio frequency circuit, a processing circuit, an audio codec circuit, a speaker and a battery. The radio frequency circuit and the audio codec circuit can be coupled to the processing circuit. Among them, the radio frequency circuit can be used to communicate with an external device to obtain an audio signal. The audio signal can be transmitted to the audio codec circuit through the processing circuit. The audio codec circuit can be used to encode and decode the audio signal. The speaker can be coupled to the audio codec circuit to convert the audio information processed by the audio codec circuit into sound output.

[0025] Among them, the radio frequency circuit may include an antenna 220, an RF (Radio Frequency) transceiver, one or more amplifiers, a tuner, an oscillator, a digital signal processor, a codec chipset, a user identity module card, etc. The radio frequency circuit can communicate with other terminals through at least one wireless communication protocol. The wireless communication protocol includes but is not limited to: World Wide Web, metropolitan area network, intranet, various generations of mobile communication networks (2G, 3G, 4G and 5G), wireless local area network and / or WiFi (Wireless Fidelity) network. In some embodiments, the radio frequency circuit may also include NFC (NearField Communication) related circuits, which are not limited in this application.

[0026] The processing circuit may also be referred to as a CPU (Central Processing Unit) or a Bluetooth main control chip. The processing circuit may be an integrated circuit chip having the ability to process signals. The processing circuit may also be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), a graphics processing unit (GPU) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The general-purpose processor may be a microprocessor (MCU) or the processor may also be any conventional processor, etc.

[0027] In addition, some wireless headphones may further include a microphone, which can be used to collect the user's voice information, transmit it to the audio codec circuit for codec processing, and then transmit it to the external device through the processing circuit and the radio frequency circuit.

[0028] The inventor of the present application has found through research that current wireless earphones are usually small in size. Due to volume limitations, the radial dimensions of some wireless earphones even need to be within 20 mm. The ideal length of the antenna 220 is generally around 30 mm, which has brought obstacles to the design and manufacture of small wireless earphones. In order to solve the above problems, the present application proposes the following embodiments.

[0029] See also Figure 3 and Figure 4 According to one or more embodiments of the present application, the antenna assembly 20 may include a circuit board 200, a first functional conductive member 210, and an antenna 220. The circuit board 200 may be disposed in the housing 10. The antenna 220 may be disposed on one side of the circuit board 200. The first functional conductive member 210 may be disposed on one side of the circuit board 200 close to the antenna and spaced apart from the circuit board 200.

[0030] The antenna 220 includes a feeding portion 221 and an antenna body 222. The feeding portion 221 is disposed on the circuit board 200. The antenna body 222 is spaced apart from the circuit board 200, and the antenna body 222 is connected to the feeding portion 221, and is electrically connected to the circuit board 200 via the feeding portion 221. The first functional conductive member 210 is electrically connected to the circuit board and to the antenna body 222 to extend the radiation path of the antenna body 222. In other words, the antenna body 222 and the first functional conductive member 210 can radiate electromagnetic waves outward together.

[0031] The first functional conductive component 210 may be a conductive component in the earphone 1. The first functional conductive component 210 may be disposed on the circuit board 200, may be spaced apart from the circuit board 200, or may be disposed on the housing 10. Optionally, the antenna body 222 is bonded to the first functional conductive component 210 by conductive adhesive.

[0032] Compared with the prior art, the present invention has the following beneficial effects: the first functional conductive member 210 and the antenna 220 are electrically connected, so the first functional conductive member 210 can also form the antenna 220 portion in the antenna assembly 20 that can radiate electromagnetic waves, thereby facilitating the reduction of the size of the antenna body 222 and further reducing the volume of the earphone 1. Specifically, when the antenna assembly 20 does not have the size of the first functional conductive member 210, the size of the antenna body 222 meets the preset size, and when the first functional conductive member 210 and the antenna body 222 are electrically connected to form the antenna assembly 20, the sum of the lengths of the antenna body 222 and the first functional conductive member 210 meets the preset size.

[0033] In addition, it should be noted that the first functional conductive component 210 can be used as a part of the antenna assembly 20 when it is electrically connected to the antenna body 222. Similarly, the first functional conductive component 210 can also play its inherent role. For example, when the first functional conductive component 210 is magnetic (described later), it can play an inherent role of magnetic connection with an external device. For another example, when the first functional conductive component 210 is a charging pole (described later), it can play an inherent role of charging. Similarly, it can be understood that the first functional conductive component 210 can also be other conductive devices in the headset. By utilizing the inherent conductive devices in the headset as a component of the antenna assembly 20, the size of the antenna body 222 can be further reduced, thereby reducing the volume of the headset.

[0034] Optionally, the antenna body 222 may be linear, curved or bent, and the length of the antenna body 222 may be the length in its extension direction. Similarly, the length of the first functional conductive member 210 may be the length of the path along its extension direction between the connection between the first functional conductive member 210 and the antenna body 222 and the end of the first functional conductive member 210 farthest from the connection. In addition, when the antenna body 222 is bent or extended in a curved manner, the space utilization rate inside the housing 10 can be improved. Optionally, the projection of the antenna body 222 on the circuit board 200 is bent and extended along the edge of the circuit board 200. In this case, the interference of the components on the circuit board 200 with the antenna body 222 can be reduced.

[0035] Optionally, the sum of the extension lengths of the antenna body 222 and the first functional conductive member 210 is between 7.5 mm and 30 mm. In this case, the antenna assembly 20 can be used to transmit and receive 2.4 GHz signals for Bluetooth communication.

[0036] Alternatively, see Figure 4 and Figure 5, the antenna assembly 20 includes a second functional conductive member 230. The first functional conductive member 210 can be electrically connected to the second functional conductive member 230. In this case, the antenna body 222, the first functional conductive member 210 and the second functional conductive member 230 can radiate electromagnetic waves outward together. In addition, the first functional conductive member 210 and the second functional conductive member 230 of the antenna assembly 20, as part of the antenna assembly 20, can further reduce the size of the antenna body 222. In this case, the sum of the extended lengths of the antenna body 222, the first functional conductive member 210 and the second functional conductive member 230 is between 7.5 mm and 30 mm.

[0037] Similarly, the second functional conductive component 230 can be a conductive component in the earphone 1, which can be a conductive component arranged on the circuit board 200, or a conductive component arranged on the housing 10. The second functional conductive component 230 can be a part of the antenna assembly when electrically connected to the antenna body, and can also play its own inherent role, which will not be described in detail here.

[0038] Optionally, the second functional conductive member 230 may be disposed on the circuit board 200 and spaced apart from the first functional conductive member 210. The circuit board 200 includes a device area 200a and a clearance area 200b, the first functional conductive member 210 is disposed in the clearance area 200b, the feeding portion 221 is disposed in the device area 200a, and the antenna 220 extends toward the first functional conductive member 210 and electrically contacts the first functional conductive member 210. The clearance area 200b is a portion of the circuit board 200 facing the antenna body 222 on which no electronic components are disposed. The device area 200a corresponds to a portion of the circuit board 200 facing the antenna body 222 on which electronic components are disposed.

[0039] Alternatively, see Figure 4 and Figure 5 , the antenna assembly 20 also includes a conductive connector 240. The conductive connector 240 connects the first functional conductive member 210 and the second functional conductive member 230 so that the first functional conductive member 210 and the second functional conductive member 230 are electrically connected to each other. Further, the conductive connector 240 can be an elastic connector, for example, a pogo pin. In this case, the conductive connector 240 can be retracted to a certain extent, and can still maintain good contact with the first functional conductive member 210 and the second functional conductive member 230 when the earphone moves violently. In other examples, the conductive connector 240 can also be a rigid connector.

[0040] Optionally, the first functional conductive member 210 is located on one side of the circuit board 200, and the second functional conductive member 230 is located on the other side of the circuit board 200. The conductive connector 240 is disposed through the circuit board 200 to contact the first functional conductive member 210 and the second functional conductive member 230 on both sides of the circuit board 200. Optionally, the antenna body 222 electrically contacts the side of the first functional conductive member 210 facing away from the circuit board 200, and the conductive connector 240 electrically contacts the side of the first functional conductive member 210 facing the circuit board 200. Optionally, the second functional conductive member 230 and the conductive connector 240 may be disposed in the clearance area 200b.

[0041] Optionally, in some embodiments, the first functional conductive member 210 is magnetic, and is used for magnetic adsorption of the earphone 1 and an external device. The first functional conductive member 210 can be arranged opposite to and spaced from the circuit board 200. Specifically, the first functional conductive member 210 can be a conductive magnet. The magnet can be used to be adsorbed on the earphone box for positioning, so as to be placed in the earphone box for charging.

[0042] Optionally, the second functional conductive member 230 is a charging pole 230a, which is used to electrically contact the charging pole 230a of an external power source to charge the earphone 1. The second functional conductive member 230 can be fixedly arranged on the circuit board 200 and electrically connected to the circuit board 200 through the second connecting line 203. In addition, since the charging pole 230a is connected to the circuit board 200, if the charging pole 230a constitutes a part of the antenna assembly 20, it may cause interference. Optionally, a magnetic bead 204 can be connected in series on the second connecting line 203 to reduce the interference caused by the circuit board 200.

[0043] It is understandable that when any one of the first functional conductive member 210 and the second functional conductive member 230 is electrically connected to the antenna body 222, it can constitute a part of the antenna 220. Therefore, removing any one of the first functional conductive member 210 and the second functional conductive member 230 does not affect the operation of the antenna assembly 20.

[0044] In some embodiments, the first functional conductive component 210 is magnetic and is used for magnetic adsorption of the earphone 1 and an external device. The first functional conductive component 210 is opposite to the circuit board 200 and is spaced apart.

[0045] In other embodiments, the first functional conductive member 210 may also be a charging pole 230a, which is used to electrically contact the charging pole 230a of an external power source to charge the earphone 1, and the charging pole 230a may be fixedly disposed on the circuit board 200. Generally, the charging pole 230a may be in pairs. The first functional conductive member 210 may include one or two charging poles 230a.

[0046] For example, the first functional conductive part 210 may include two charging poles 230a. The two charging poles 230a may be connected in series and coupled to the antenna body 222. That is, the first functional conductive part 210 may be a charging pole 230a. The number of the first functional conductive parts 210 is two, and the circuit board 200 is provided with a first connecting line 201. The first connecting line 201 may electrically connect the two first functional conductive parts 210. In this case, the antenna assembly 20 may include a circuit board 200, an antenna 220, and two charging poles 230a.

[0047] A capacitor may be connected in series to the first connection line 201. For example, the first connection line 201 may be connected in series to a capacitor 202 between two charging poles 230a. In this case, the charging current of the wireless headset is generally direct current, and the risk of short circuit between the two charging poles 230a when the headset is charged can be reduced by providing the capacitor 202. In addition, since the RF signal received and transmitted by the antenna 220 is an AC signal, the antenna 220 can still receive and transmit the RF signal normally.

[0048] In addition, the circuit board 200 is provided with two second connection lines 203 electrically connected to the two charging poles 230a respectively. The two second connection lines 203 may correspond to the two charging poles 230a one by one. Each charging pole 230a is electrically connected to the circuit board 200 through the corresponding second connection line 203. A magnetic bead 204 may be connected in series to at least one second connection line 203. In this case, the interference caused by the circuit board 200 can be reduced.

[0049] In other embodiments, the antenna assembly 20 may include a first functional conductive member 210 and a second functional conductive member 230. The first functional conductive member 210 may be magnetic. The second functional conductive member 230 may include two charging poles 230a. The two charging poles 230a may also be connected in series and coupled to the first functional conductive member 210.

[0050] That is, the second functional conductive member 230 may be a charging pole 230a. The number of the second functional conductive members 230 is two, and the circuit board 200 is provided with a first connecting line 201 electrically connected to the two second functional conductive members 230. In this case, the antenna assembly 20 may include the circuit board 200, the first functional conductive member 210, the two charging poles 230a and the antenna 220.

[0051] Furthermore, the first connection circuit 201 is connected in series with a capacitor 202 between two second functional conductive members 230. In addition, the circuit board 200 is provided with two second connection circuits 203 electrically connected to the two second functional conductive members 230 in a one-to-one correspondence. Each second functional conductive member 230 is electrically connected to the circuit board 200 through the corresponding second connection circuit 203, and each second connection circuit 203 is connected in series with a magnetic bead 204.

[0052] According to other embodiments of the present application, the antenna assembly 20 may include a first functional conductive member 210. The first functional conductive member 210 may include only one charging pole 230a. Only one of the two charging poles 230a is connected to the antenna body 222. That is, the first functional conductive member 210 is a charging pole 230a. The number of the first functional conductive member 210 is one. In this case, the antenna assembly 20 may include a circuit board 200, one charging pole 230a, and an antenna 220.

[0053] Furthermore, the charging pole 230a is electrically connected to the circuit board 200 via the second connecting line 203. A magnetic bead 204 may be serially connected to the second connecting line 203. In this case, the other charging pole 230a does not constitute a part of the antenna assembly 20, so there is no need to set the first connecting line 201 to electrically connect the two charging poles 230a.

[0054] In some other embodiments, the antenna assembly 20 may include a first functional conductive member 210 and a second functional conductive member 230. The first functional conductive member 210 may be magnetic. The second functional conductive member 230 may include a charging pole 230a. Only one of the two charging poles 230a is connected to the first functional conductive member 210.

[0055] That is, the second functional conductive member 230 is a charging pole 230a. The number of the second functional conductive member 230 is one. In this case, the antenna assembly 20 may include a circuit board 200, a first functional conductive member 210, a charging pole 230a and an antenna 220. Further, the charging pole 230a is electrically connected to the circuit board 200 via a second connecting line 203. A magnetic bead 204 may be connected in series to the second connecting line 203.

[0056] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
