[0003] The embodiment of the present application provides an earphone and an audio device, which solve the problem that the earphone body located behind the ear has a large overall volume in the existing ear clip type earphone, resulting in uncomfortable wearing for the user.

[0004] To achieve the above object, the embodiment of the present application adopts the following technical scheme:

[0005] The first aspect of the embodiment of the present application provides an earphone, which includes a first earphone body, a second earphone body and a connecting arm, the connecting arm connects the first earphone body and the second earphone body, when the user wears the earphone, the first earphone body is clamped in the concha cavity of the user, and the second earphone body is located outside the ear of the user; the second earphone body includes a shell, the shell close to the ear of the user is provided as a curved surface matched with the shape of the ear; a main board, the main board is arranged in the shell, the main board includes a first side and a second side arranged oppositely, the first side is located at the side of the shell provided with the curved surface, in use, the first side is arranged close to the ear of the user, and the second side is arranged away from the ear of the user; an antenna, the antenna is arranged close to the second side; an inductor, the inductor is connected with the main board and located at the second side; a shielding member, the shielding member is arranged between the antenna and the inductor.

[0006] Therefore, in the wearing state, the first earphone body is located in the concha cavity of the user and is fitted with the concha cavity, and the second earphone body abuts behind the ear of the user, at this time, a certain clamping force is formed between the outer walls of the first earphone body and the second earphone body to the ear. Since this ear clip type earphone does not need to stretch into the ear canal of the user when worn, it can reduce the ear canal allergy and injury, and the user can perceive the change of the surrounding environment at any time, which is beneficial to reduce the risk of accidents.

[0007] In use of the earphone, the side of the shell provided with the curved surface is close to the user's ear for wearing, the earphone is more close-fitting to the user's ear in use, the clamping is more firm, the earphone is not easy to fall off, and the user is more comfortable in wearing. In addition, the shell close to the user's ear is provided with the curved surface, and when the curvature of the curved surface is small to be close to the user's ear and the curvature of the shell away from the user's ear is large to accommodate more components, the space height between the curved surface and the first side is less than the space height between the shell away from the user's ear and the second side, since the height of the inductor is large, the inductor is arranged on the second side of the mainboard, compared with all the electronic devices arranged on the first side, the distance between the mainboard and the shell close to the user's ear can be shortened, and then the space is saved and the volume of the second earphone body is reduced.

[0008] The shielding member is arranged between the inductor and the antenna, and the shielding member can block the magnetic field of the inductor from spreading outward to the area where the antenna is located, thereby causing interference to the antenna.

[0009] In an optional implementation, the earphone further includes a battery, the battery is arranged between the shielding member and the antenna, and a conductive member, the negative electrode of the battery is electrically connected to the shielding member through the conductive member.

[0010] Therefore, the battery is arranged adjacent to the shielding member, the length of the power supply line between the shielding member and the battery can be shortened, wiring design is simplified, and line impedance is reduced. By effectively grounding the shielding member, the coupling of electromagnetic interference generated when the inductor works to the antenna can be inhibited. In addition, the grounding design can also effectively guide away the spurious interference generated when the battery and the antenna work cooperatively.

[0011] In an optional implementation, the shielding member is at least partially overlapped with the battery in a direction perpendicular to the plane of the mainboard, and the conductive member includes conductive foam, and the overlapping area of the shielding member and the battery is provided with the conductive foam.

[0012] Therefore, when the conductive foam is used to realize the electrical connection between the shielding member and the battery, the conductive foam is arranged in the overlapping area of the shielding member and the battery, the contact area of the conductive foam and the shielding member and the contact area of the conductive foam and the battery can be increased, the connection is more stable and firm, the reliability during connection is improved, and the fluctuation of contact resistance is effectively reduced.

[0013] In an optional implementation, the earphone further includes a magnetic member, and the magnetic member is arranged between the battery and the antenna.

[0014] Therefore, the magnetic member in the charging box can be magnetically attracted to realize magnetic attraction, so that the earphone can be accurately positioned in the charging box, thereby ensuring the reliability of the charging contact.

[0015] In an optional implementation, the magnetic member includes any one of silicon steel, manganese-zinc ferrite, nickel-zinc ferrite, or nanocrystalline.

[0016] In this way, the magnetic member is made of soft magnetic material, and can guide the interference magnetic field to deviate from the antenna radiation area.

[0017] In an optional implementation, the shielding member is in a U shape in a direction perpendicular to the plane of the main board, two ends of the U shape are connected to the main board, and the inductor is located in an opening of the U shape.

[0018] In this way, the vertical surface of the shielding member is connected to the main board, which can improve the rigidity of the main board, thereby avoiding deformation of the main board or stress concentration when the second earphone body is impacted.

[0019] In an optional implementation, the earphone further includes a chip, the chip is connected to the main board and located on the second side.

[0020] In this way, the first side of the main board is arranged opposite to the curved surface, and the size of the chip is large, the chip is arranged on the second side of the main board, compared with being arranged on the first side, the distance between the main board and the shell close to the user's ear can be shortened, thereby the volume of the second earphone body can be reduced.

[0021] In an optional implementation, the antenna includes a first antenna unit and a second antenna unit, and the first antenna unit and the second antenna unit have different working frequency bands.

[0022] In this way, through the cooperative work of the dual frequency bands, the connection stability of the earphone can be enhanced, and intelligent switching to the optimal frequency band can be performed in a complex wireless environment to reduce interference.

[0023] In an optional implementation, the earphone further includes a radio frequency assembly located on the second side, the radio frequency assembly is connected to the main board, and the radio frequency assembly is electrically connected to the chip.

[0024] In this way, the radio frequency assembly and the chip are both arranged on the second side of the main board, the connection distance between the radio frequency assembly and the chip can be shortened, and the transmission loss can be reduced.

[0025] In an optional implementation, the radio frequency assembly includes an amplifier and a switch, one end of the amplifier is electrically connected to the chip, the other end of the amplifier is connected to the switch, and one end of the switch away from the amplifier is connected to an antenna interface.

[0026] In this way, the amplifier is arranged close to the chip, which can improve the signal transmission power, and the switch is arranged away from the chip, which can reduce the insertion loss. In addition, the amplifier and the antenna are arranged separately, which can effectively suppress mutual interference and improve the electromagnetic compatibility performance of the system.

[0027] In an alternative implementation, the earphone further comprises an electrical connector connected to the main board and located on the first side, and the electrical connector is electrically connected to the antenna.

[0028] In this way, the electrical connector occupies less space when electrically connected to the antenna, and the electrical connector is arranged on the first side of the main board, so that the distance between the main board and the shell on the side close to the user's ear is not increased, and thus the miniaturization design of the second earphone body is not affected.

[0030] In this way, the sound wave from the outside can be collected and conducted to the microphone in the shell, so that clear environmental sound pickup and call noise reduction functions are achieved. The sound pickup surface is arranged opposite the sound pickup hole, so that a sound pickup pipeline does not need to be arranged between the sound pickup surface and the sound pickup hole, the structure is simplified, and thus the volume of the second earphone body is reduced.

[0031] In an alternative implementation, the earphone further comprises a protective cover arranged in the sound pickup hole.

[0032] In this way, the protective cover can effectively prevent dust and impurities from entering the sound pickup hole, so that the sound pickup sensitivity is not reduced due to blockage.

[0062] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0063] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0064] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0065] The present invention provides an audio device comprising: headphones and a headphone box, wherein the headphones are arranged in the headphone box. The headphones can be in various forms such as in-ear, ear clip, bone conduction, head-mounted, etc.

[0066] An embodiment of the present application provides an earphone for use with the audio device described above. The earphone may be, for example, an earclip-type earphone, and thus can be clamped on the user's ear without blocking the ear canal for fixation, thereby alleviating discomfort in the user's ear and improving comfort when worn.

[0067] For example, Figure 1 This is a schematic diagram of the structure of a headset provided in an embodiment of the present application. Figure 1 As shown, the earphone 1000 includes a first earphone body 100, a second earphone body 200, and a connecting arm 300. The connecting arm 300 connects the first earphone body 100 and the second earphone body 200. When the user wears the earphone 1000, the first earphone body 100 is retained within the user's cavum concha, while the second earphone body 200 is located outside the user's ear. Thus, when worn, the first earphone body 100 is located within and in contact with the user's cavum concha, while the second earphone body 200 abuts against the back of the user's ear. At this time, the outer walls of the first earphone body 100 and the second earphone body 200 exert a certain clamping force on the ear. Because these ear clip earphones do not need to be inserted into the user's ear canal when worn, they can reduce ear canal allergies and damage. Furthermore, the user can be aware of changes in the surrounding environment at any time, which helps reduce the risk of accidents.

[0068] When a user uses the earphone 1000, the first earphone body 100 can be used to produce sound. For example, the second earphone body 200 can include a speaker. The second earphone body 200 can also be used to pick up external noise. For example, the second earphone body 200 can include a microphone.

[0069] The structure of the second earphone body 200 is described below.

[0070] For example,Figure 2 is a schematic diagram of an exploded structure of a second earphone body, Figure 3 is Figure 2 is a schematic diagram of a structure of a circuit board of the second earphone body. As shown in Figure 2 , the second earphone body 200 includes an upper housing 210 and a lower housing 220, the upper housing 210 and the lower housing 220 enclose a containing space, a mainboard assembly 230, a battery body 240 and an antenna module 250 are arranged in the containing space, the mainboard assembly 230 is arranged close to the upper housing 210, and the antenna module 250 is arranged close to the lower housing 220. As shown in Figure 3 , the mainboard assembly 230 includes a circuit board 231, an electrical connector 232 and a main chip 233 arranged on the circuit board 231.

[0071] The circuit board 231 includes a first side arranged close to the upper housing 210 and a second side arranged away from the upper housing 210, the first side of the circuit board 231 is provided with the electrical connector 232 and the main chip 233, and the second side is sequentially provided with the battery body 240 and the antenna module 250.

[0072] In order to improve the clamping effect of the first earphone body 100 and the second earphone body 200 on the ear, the upper housing 210 in the second earphone body 200 is arranged close to the ear of the user, and therefore the shape of the upper housing 210 is arranged to be fitted to the shape of the ear, resulting in that the curvature of the upper housing 210 is arranged to be relatively small, and in order to accommodate multiple structures such as the battery body 240 and the antenna module 250, the curvature of the lower housing 220 is arranged to be relatively large.

[0073] In order to accommodate the electrical connector 232, the main chip 233 and other multiple electronic devices, and the height of the main chip 233 is relatively large, it is necessary to increase the distance between the circuit board 231 and the upper housing 210 to avoid the electronic devices being pressed against the inner surface of the upper housing 210 and affecting the use effect, thus being not conducive to the miniaturization design of the second earphone body 200.

[0074] Therefore, the embodiment of the present application provides an earphone, by arranging the electronic devices in the second earphone body 200 on the opposite sides of the circuit board respectively, for example, arranging the electrical connector on the side of the circuit board close to the first housing, and arranging the chip and the inductor and other structures with relatively large size on the side of the circuit board away from the first housing, the distance between the circuit board and the first housing can be shortened to reduce the volume of the second earphone body 200.

[0075] Figure 4 is a schematic diagram of a structure of a second earphone body, Figure 5 is Figure 4 is a schematic diagram of an exploded structure of the second earphone body. As shown in Figure 5As shown, the second earphone body 200 in the embodiment of the present application comprises a shell 1, and a mainboard 2, an antenna 3 and an inductor 4 arranged in the shell 1. The shell 1 near the user's ear is arranged as a curved surface matching the shape of the ear. The mainboard 2 comprises a first side 201 and a second side 202 arranged oppositely. The first side 201 is arranged on the side of the shell 1 provided with the curved surface, and is arranged close to the user's ear during use. The second side 202 is arranged away from the user's ear. The antenna 3 is arranged close to the second side 202. The inductor 4 is connected with the mainboard 2 and is arranged on the second side 202.

[0076] As shown in the Figure 5 shell 1 comprises a first shell 101 and a second shell 102. The first shell 101 and the second shell 102 enclose a receiving cavity. The mainboard 2, the antenna 3 and the inductor 4 are arranged in the receiving cavity. The mainboard 2 is arranged close to the first shell 101, and the first side 201 of the mainboard 2 is arranged opposite to the first shell 101. The antenna 3 is arranged close to the second shell 102.

[0077] The first shell 101 and the second shell 102 are both arranged as curved surfaces. During use, the first shell 101 is arranged close to the user's ear. Therefore, the curvature of the first shell 101 is set smaller, and the curvature of the second shell 102 is set larger.

[0078] In the embodiment of the present application, the antenna 3 is used for wireless signal transmission.

[0079] In other embodiments, the antenna 3 can not be arranged in the second earphone body 200, and a wired connection can be used to connect the earphone with a mobile phone, a computer or other devices.

[0080] The number of the antennas 3 is not limited in the embodiment of the present application. For example, Figure 6 As shown in the Figure 5 structure diagram of the antenna of the second earphone body. As shown in the Figure 6 The antenna 3 comprises a first antenna unit 301 and a second antenna unit 302. The working frequency bands of the first antenna unit 301 and the second antenna unit 302 are different. In this way, the antenna 3 works cooperatively through double frequency bands, which can enhance the connection stability of the earphone, and intelligently switch to the optimal frequency band in a complex wireless environment to reduce interference.

[0081] For example, the first antenna unit 301 is designed to support the frequency band used by the 2G network, such as 900MHz. The second antenna unit 302 is designed to support the frequency band used by the 5G network, such as 3.5GHz.

[0082] In other embodiments, the antenna 3 can comprise only one antenna unit, or three or more antenna units.

[0083] In some embodiments, the first antenna unit 301 and the second antenna unit 302 are designed to support frequency bands used by any two of 2G, 3G, 4G and 5G networks.

[0084] In use of the earphone 1000, the side of the shell 1 provided with the curved surface is worn close to the user's ear. In use, the earphone 1000 is more fitted to the user's ear, the clamping is more firm, the earphone 1000 is less likely to fall off, and the user is more comfortable in wearing. In addition, the shell 1 close to the user's ear is provided with a curved surface, and when the curvature of the curved surface is set to be small to fit the user's ear and the curvature of the shell 1 away from the user's ear is set to be large to accommodate more components, the space height between the curved surface and the first side 201 is less than the space height between the shell 1 away from the user's ear and the second side 202. Since the height of the inductor 4 is large, the inductor 4 is arranged on the second side 202 of the mainboard 2. Compared with all electronic devices arranged on the first side 201, the distance between the mainboard 2 and the shell 1 close to the user's ear can be shortened, thereby saving space and reducing the volume of the second earphone body 200.

[0085] The inductor 4 in the embodiment of the present application is arranged on the second side 202 of the mainboard 2. In order to avoid interference of the inductor 4 on the antenna 3, a shielding member is arranged between the inductor 4 and the antenna 3.

[0086] As shown in Figure 5 , the second earphone body 200 further comprises a shielding member 5 arranged between the antenna 3 and the inductor 4. Thus, the shielding member 5 is arranged between the inductor 4 and the antenna 3. The shielding member 5 can block the magnetic field of the inductor 4 from spreading outward to the area where the antenna 3 is located, thereby avoiding interference of the inductor 4 on the antenna 3.

[0087] The shape of the shielding member 5 is not limited in the embodiment of the present application. For example, Figure 7 As shown in Figure 5 , the structure diagram of the connection between the shielding member and the mainboard of the second earphone body, the length direction of the mainboard 2 can be x direction, the width direction of the mainboard 2 can be y direction, and the thickness direction of the mainboard 2 can be z direction. As shown in Figure 7 , the shape of the shielding member 5 is U-shaped along the direction perpendicular to the plane of the mainboard 2, i.e. along the direction of the xz plane. The two ends of the U-shaped shielding member 5 are connected with the mainboard 2, and the inductor 4 is located in the opening of the U-shaped shielding member 5.

[0088] As shown in Figure 7 , the shielding member 5 comprises a bottom plate 501 and side plates 502 vertically connected on both sides of the bottom plate 501. The bottom plate 501 and the two side plates 502 form a U-shaped structure.

[0089] Therefore, the side plate 502 of the shielding member 5 is connected to the main board 2, which can improve the rigidity of the main board 2 and thereby prevent the main board 2 from being deformed or stress concentration from occurring when the second earphone body 200 is hit.

[0090] In other embodiments, the shielding member 5 may also only include the bottom plate 501 , and the bottom plate 501 is connected to the main board 2 by glue potting.

[0091] In other embodiments, one end of the side plate 502 of the shielding member 5 away from the bottom plate 501 may also be connected to the battery located on the second side 202 of the main board 2 .

[0092] The shielding member 5 in the embodiment of the present application is made of magnetic and conductive materials such as copper and tinned steel.

[0093] like Figure 5 As shown, the headset further includes a battery 6, which is disposed between the shielding member 5 and the antenna 3. Thus, the battery 6 is disposed adjacent to the shielding member 5, which can shorten the length of the power supply line between the shielding member 5 and the battery 6, thereby simplifying the wiring design and reducing the line impedance.

[0094] In order to improve the shielding performance of the shielding element 5 on signals, the shielding element 5 is grounded in the embodiment of the present application.

[0095] For example, Figure 8 for Figure 5 The schematic diagram of the structure of the connection between the shielding part of the second earphone body, the main board and the battery is shown. Figure 8 As shown, the earphones further include a conductive member 7, through which the negative terminal of the battery 6 is electrically connected to the shielding member 5. Thus, by effectively grounding the shielding member 5, the coupling of electromagnetic interference generated by the inductor 4 during operation to the antenna 3 can be suppressed. Furthermore, this grounding design effectively deflects clutter interference generated when the battery 6 and antenna 3 work together.

[0096] In order to improve the stability of the shielding member 5 when connected, Figure 9 for Figure 4 AA cross-section structure diagram. Figure 9 As shown, along the direction perpendicular to the plane of the main board 2, that is, along the direction perpendicular to the xy plane (as shown Figure 7 As shown in FIG, shielding member 5 and battery 6 are arranged overlappingly, and conductive member 7 includes conductive foam, which is disposed in the overlapping region of shielding member 5 and battery 6. Therefore, when conductive foam is used to achieve electrical connection between shielding member 5 and battery 6, disposing the conductive foam in the overlapping region of shielding member 5 and battery 6 increases the contact area between the conductive foam and shielding member 5, and between the conductive foam and battery 6, making the connection more stable and secure, improving connection reliability, and effectively reducing fluctuations in contact resistance.

[0097] In some other embodiments, the shielding member 5 can also partially overlap the battery 6.

[0098] For example, the conductive member 7 is conductive foam.

[0099] In some other embodiments, the conductive member 7 can also be conductive cloth tape or conductive silica gel or other conductive materials, and the embodiments of the present application do not limit the material of the conductive member 7.

[0100] The charging box and the earphone 1000 in the embodiments of the present application are both internally provided with a magnet, which can be used to assist the earphone 1000 in quickly positioning when the earphone 1000 is charging in the paired charging box.

[0101] For example, Figure 10 For Figure 4 The B-B cross-sectional structure diagram of the second earphone body is shown. As shown in Figure 5 , Figure 10 The earphone further includes a magnetic member 8, which is arranged between the battery 6 and the antenna 3. Thus, the magnetic member 8 can realize magnetic attraction with the corresponding magnetic member in the charging box, so as to ensure the accurate positioning of the earphone in the charging box, thereby ensuring the reliability of the charging contact.

[0102] The magnetic member 8 in the embodiments of the present application includes any one of silicon steel, manganese zinc ferrite, nickel zinc ferrite, and nanocrystalline composite. Thus, the magnetic member 8 is made of soft magnetic material, which can guide the interference magnetic field to deviate from the antenna 3 radiation area.

[0103] For example, the magnetic member 8 is made of one of silicon steel, manganese zinc ferrite, nickel zinc ferrite, and nanocrystalline composite.

[0104] The difference between soft magnetic material and hard magnetic material is described as follows:

[0105] Soft magnetic material: only a small external magnetic field is needed to be magnetized, and the magnetism disappears quickly after the external magnetic field is removed, the magnetic induction intensity is small, the energy loss in the magnetization and demagnetization process is small, and the external magnetic field is very sensitive.

[0106] Hard magnetic material: a very strong external magnetic field is needed to be magnetized, and the magnetism can be maintained for a long time after the external magnetic field is removed, the magnetic induction intensity is strong, the energy loss in the magnetization and demagnetization process is large, and the external magnetic field is very slow.

[0107] The main board 2 in the embodiments of the present application is also provided with a processor, for example, a chip, for receiving and transmitting wireless signals, and realizing other functions of the earphone 1000.

[0108] Figure 11 For Figure 5A structural schematic diagram of the second side of the mainboard of the second earphone body is shown. As Figure 11 As shown, the earphone further comprises a chip 9 connected with the mainboard 2 and located at the second side 202. Thus, the first side 201 of the mainboard 2 is arranged opposite to the curved surface, and the chip 9 has a large size. Compared with being arranged at the first side 201, arranging the chip 9 at the second side 202 of the mainboard 2 can shorten the distance between the mainboard 2 and the shell 1 close to the user's ear, and further reduce the volume of the second earphone body 200.

[0109] The antenna 3 in the embodiment of the present application supports two signals of 2G and 5G. In order to avoid mutual interference between the two signals, a radio frequency component 10 is arranged in the embodiment of the present application for signal transmission.

[0110] As shown, Figure 11 As shown, the earphone further comprises a radio frequency component 10 located at the second side 202, the radio frequency component 10 being connected with the mainboard 2, and the radio frequency component 10 being electrically connected with the chip 9. Thus, the radio frequency component 10 and the chip 9 are both arranged at the second side 202 of the mainboard 2, which can shorten the connection distance between the radio frequency component 10 and the chip 9, and reduce the transmission loss.

[0111] As shown, Figure 12 A structural schematic diagram of the connection between the chip and the radio frequency component is provided in the embodiment of the present application. As shown, Figure 12 As shown, the radio frequency component 10 comprises an amplifier 1001 and a switch 1002, one end of the amplifier 1001 is electrically connected with the chip 9, the other end of the amplifier 1001 is connected with the switch 1002, and one end of the switch 1002 away from the amplifier 1001 is connected with an antenna interface 1003. Thus, the amplifier 1001 is arranged close to the chip 9, which can improve the signal transmission power, and the switch 1002 is arranged away from the chip 9, which can reduce the insertion loss. In addition, the amplifier 1001 is arranged separately from the antenna 3, which can effectively suppress mutual interference and improve the system electromagnetic compatibility performance.

[0112] The chip 9 supports two communication standards of 2G and 5G, and the chip 9 comprises two radio frequency signal transceiver ports of “2G TRX” and “5G TRX” for transmitting and receiving wireless signals of different frequency bands.

[0113] As shown, Figure 12 As shown, the amplifier 1001 comprises a power amplifier (PA) and a low noise amplifier (LNA). The 2G signal and the 5G signal are both configured with corresponding power amplifiers and low noise amplifiers.

[0114] When transmitting a signal, the switch 1002 is connected with the power amplifier, and when receiving a signal, the switch 1002 is connected with the low noise amplifier.

[0115] As shown in Figure 12 , the antenna interface 1003 includes two antenna interfaces of "Ant_0 5G / 2G+" and "Ant_1 2G". Among them, the "Ant_0" interface is a common antenna interface supporting the frequency bands corresponding to 5G and 2G+, and the "Ant_1" interface is an antenna interface supporting the frequency bands corresponding to 2G.

[0116] As shown in Figure 12 , in order to ensure the purity of the signal, a filter 1004 is also arranged between the chip 9 and the amplifier 1001. Among them, the "2G TRX" and "5G TRX" ports are connected to the power amplifier or low noise amplifier through the filter 1004.

[0117] As shown in Figure 12 , in order to improve the quality and stability of communication, two tuners 1005 of "Tuner_0" and "Tuner_1" are also arranged between the amplifier 1001 and the antenna interface 1003.

[0118] When transmitting a wireless signal, the chip 9 dynamically selects the TRX port to output the radio frequency signal according to the 2G / 5G communication standard. The radio frequency signal is first filtered by the filter 1004 to remove noise, then amplified to sufficient power by the power amplifier, and then adjusted by the tuner 1005 to a state suitable for transmission by the antenna 3, and transmitted by the antenna 3.

[0119] After the antenna 3 receives the radio frequency signal from the outside, it is first adjusted by the tuner 1005 for impedance matching, then amplified by the low noise amplifier, then filtered by the filter 1004 to remove noise and interference signals, and finally enters the chip 9 for signal processing.

[0120] In order to improve the stability of the electrical connection between the antenna 3 and the mainboard 2, Figure 13 As shown in Figure 5 , the structure diagram of the first side of the mainboard of the second earphone body, Figure 14 As shown in Figure 5 , the structure diagram of the connection between the mainboard and the antenna of the second earphone body. As shown in Figure 13 , the earphone further includes an electrical connector 11, which is connected to the mainboard 2 and located on the first side 201, and the electrical connector 11 is electrically connected with the antenna 3 (as shown in Figure 14 ). Therefore, the electrical connector 11 occupies less space when it is electrically connected with the antenna 3. By arranging the electrical connector 11 on the first side 201 of the mainboard 2, the distance between the mainboard 2 and the shell 1 close to the user's ear is not increased, thereby not affecting the miniaturization design of the second earphone body 200.

[0121] For example, the electrical connection 11 can be a board to board connector (BTB).

[0122] In other embodiments, the antenna 3 can also be directly soldered to the contacts of the main board 2.

[0123] The above embodiments introduce the positional relationship between the main board 2, the antenna 3, the shielding member 5, the battery 6, the magnetic member 8, and the shell 1. The following describes the setting mode of the microphone.

[0124] For example, Figure 15 For Figure 2 The second earphone body is shown in a partial cross-sectional structural schematic view. As shown in Figure 15 The lower shell 220 is provided with a sound pickup through hole 221, and the lower shell 220 is provided with a support 260. The support 260 is provided with a pipe 261. One end of the pipe 261 is opposite to and communicates with the sound pickup through hole 221, and the other end of the pipe 261 is opposite to a sound pickup surface of a microphone structure 270.

[0125] The sound pickup surface of the microphone structure 270 is communicated with the sound pickup through hole 221 through the pipe 261, which requires an additional sound guide support 260, resulting in an increase in the internal structure of the second earphone body 200 and an increase in the volume of the second earphone body 200 to some extent.

[0126] Therefore, in the embodiments of the present application, the sound pickup surface of the microphone is directly opposite to the sound pickup hole, and the sound guide support is omitted, thereby simplifying the internal layout of the shell, reducing the structural complexity, and compressing the volume of the second earphone body 200.

[0127] For example, Figure 16 For Figure 4 The second earphone body is shown in a partial structural schematic view. As shown in Figure 16 The second shell 102 in the embodiments of the present application is provided with a sound pickup hole 1021. Thus, external sound waves can be collected and conducted to the microphone inside the shell 1, realizing clear environmental sound pickup and call noise reduction functions.

[0128] For example, Figure 17 For Figure 16 The second earphone body is shown in a partial cross-sectional structural schematic view, Figure 18 For Figure 17 The second earphone body is shown in a partial cross-sectional structural schematic view, Figure 16 , Figure 18As shown in FIG. 1, the earphone further comprises a microphone 12, which is arranged in the second housing 102, and a sound pickup surface of the microphone 12 is arranged opposite to the sound pickup hole 1021. In this way, the sound pickup surface is arranged opposite to the sound pickup hole 1021, without a sound pickup pipeline arranged between the two, so that the structure can be simplified, and the volume of the second earphone body 200 can be reduced.

[0129] As shown in FIG. 1, Figure 16 , Figure 18 As shown in FIG. 1, the earphone further comprises a protective cover 13 arranged in the sound pickup hole 1021. In this way, the protective cover 13 can effectively block dust and impurities from entering the sound pickup hole 1021, so that the sound pickup sensitivity can be prevented from being reduced due to blockage. In addition, the protective cover 13 is arranged without extending outside the sound pickup hole 1021, so that the volume of the second earphone body 200 is not increased.

[0130] For example, as shown in FIG. 1, Figure 16 the sound pickup hole 1021 is circular, and the protective cover 13 comprises a first circular bottom surface 1301 and a first annular side surface 1302, the first annular side surface 1302 abuts against an inner side wall of the sound pickup hole 1021, and the first circular bottom surface 1301 is connected to an end of the first annular side surface 1302 away from the inner side wall of the second housing 102. In this way, the first circular bottom surface 1301 can be used to block dust and impurities, and the first annular side surface 1302 can increase the contact area with the inner side wall of the sound pickup hole 1021, so that the connection tightness is improved.

[0131] In other embodiments, the protective cover 13 can only comprise the first circular bottom surface 1301, and the first circular bottom surface 1301 abuts against the inner side wall of the sound pickup hole 1021.

[0132] The first circular bottom surface 1301 can be made of steel mesh. In this way, the steel mesh is hard in material, easy to clean, and not easy to be damaged.

[0133] In other embodiments, the first circular bottom surface 1301 can also be made of copper mesh, aluminum mesh, or metal woven mesh.

[0134] As shown in FIG. 1, Figure 16 , Figure 18 the earphone further comprises a support seat 14 connected to the inner side wall of the second housing 102, and the microphone 12 is connected to the protective cover 13 through the support seat 14. In this way, the position of the protective cover 13 in the sound pickup hole 1021 can be fixed, so that the protective cover 13 cannot fall into the housing 1 to fail to protect the sound pickup surface of the microphone 12.

[0135] For example, as shown in FIG. 1, Figure 16As shown, the support seat 14 includes a second circular bottom surface 1401 and a second annular side surface 1402 connected with the inner side wall of the first annular side surface 1302, and the second circular bottom surface 1401 is connected with one end of the second annular side surface 1402 away from the outer side wall of the second shell 102.

[0136] In some other embodiments, the support seat 14 can also only include the second circular bottom surface 1401, and the first annular side surface 1302 of the protective cover 13 is connected with the second circular bottom surface 1401 after extending out of the sound pickup hole 1021.

[0137] In some other embodiments, the protective cover 13 can also only include the first circular bottom surface 1301, and the second annular side surface 1402 is connected with the first circular bottom surface 1301 after extending into the sound pickup hole 1021.

[0138] In some other embodiments, the size of the second circular bottom surface 1401 is greater than the size of the sound pickup hole 1021. Thus, the area of the second circular bottom surface 1401 beyond the sound pickup hole 1021 is bonded and fixed with the inner side wall of the second shell 102 through the back adhesive 15.

[0139] In the embodiments of the present application, the support seat 14 is provided with a through hole, and the through hole is arranged opposite to the sound pickup surface. Thus, the support seat 14 can avoid blocking the propagation of sound, and ensure that the sound wave can pass through the sound pickup hole 1021 without obstruction.

[0140] In some other embodiments, the through hole is arranged in a staggered manner with the sound pickup surface, so as to avoid impurities such as dust and oil stains from entering the sound pickup hole 1021 and adhering to the sound pickup surface.

[0141] As shown in Figure 16 , Figure 18 The earphone further includes a waterproof and breathable film 16 arranged between the microphone 12 and the support seat 14. Thus, the liquid water can be blocked from entering the shell 1, and the air molecules can freely pass through, ensuring that the sound wave conduction is not affected.

[0142] The waterproof and breathable film 16 is made of materials such as Polytetrafluoroethylene (PTFE) and Thermoplastic Polyurethane (TPU).

[0143] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
