Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a wireless earphone and a charging device. Background Art

[0002] A Flexible Printed Circuit (FPC) antenna is provided in a True Wireless Stereo (TWS) earphone. As shown in, for example, Figure 1 the radiator of the FPC antenna is constituted by FPC 101. The FPC 101 is in electrical connection with the radio frequency devices on the main board 102 by abutting against two elastic pieces 103 on the main board 102. Among them, no electronic devices can be arranged around the elastic pieces 103 to meet the clearance anti-interference requirements of the elastic pieces 103, resulting in a relatively large occupied space of the elastic pieces 103 on the main board 102. A relatively large-sized main board 102 is required to meet the functional requirements of the TWS earphone, and further resulting in a relatively large overall volume of the TWS earphone. Summary of the Invention

[0003] The objective of the embodiments of this application is to provide a wireless earphone and a charging device to solve the problem of the relatively large overall volume of the TWS earphone in the related art.

[0004] In a first aspect, the embodiments of this application provide a wireless earphone, which includes: a housing, a main board, a flexible printed circuit (FPC), a conductive member, and a charging terminal. Among them, the FPC constitutes the radiator of the FPC antenna, and the radio frequency circuit of the FPC antenna is arranged on the main board;

[0005] The main board, the FPC, and the conductive member are received in the receiving cavity of the housing, and the main board and the FPC are arranged at intervals;

[0006] The charging terminal extends into the receiving cavity and is electrically connected to the radio frequency circuit, and the conductive member is electrically connected to the charging terminal;

[0007] The conductive member can move to be in a first state or a second state. When the conductive member moves to be in the first state, the conductive member abuts against the FPC, and the radio frequency circuit on the main board feeds power to the FPC through the charging terminal and the conductive member;

[0008] When the conductive member moves to be in the second state, the conductive member is arranged at intervals from the FPC, and the charging terminal is used to transmit a charging signal.

[0009] Second aspect, an embodiment of the present application provides a charging device, which is matched with the wireless earphone as described in the first aspect, and a magnetic member is provided in the charging device.

[0010] In the embodiment of the present application, the FPC constitutes the radiator of the FPC antenna, and the radio frequency circuit of the FPC antenna is arranged on the main board. By electrically connecting the conductive member to the charging terminal, and the charging terminal is electrically connected to the radio frequency circuit on the main board. In this way, when the conductive member moves to abut against the FPC, the feeding signal provided by the radio frequency circuit can be transmitted to the FPC through the charging terminal and the conductive member in sequence, so as to realize the feeding function of the FPC antenna and enable the FPC antenna to radiate signals; when the conductive member moves to be spaced from the FPC, the electrical connection between the radio frequency circuit and the FPC is disconnected. At this time, the charging terminal is used to transmit the charging signal. Therefore, the charging terminal and the conductive member can be reused to realize the electrical connection between the FPC and the radio frequency circuit on the main board. Compared with the related art, in which two elastic pieces need to be arranged on the main board to realize the electrical connection between the FPC and the radio frequency circuit on the main board, the charging terminal and the conductive member do not occupy additional space on the main board, and a smaller-sized main board can meet the functional requirements of the wireless earphone, thereby reducing the overall volume of the wireless earphone.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data may be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0023] Next, with reference to the accompanying drawings, the wireless earphone and the charging device provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0024] Referring to Figure 2 、 Figure 3 and Figure 4 a wireless earphone 100 provided in an embodiment of the present application includes: a housing 10, a main board 20, an FPC 30, a conductive member 40, and a charging terminal 50. Among them, the FPC 30 constitutes a radiator of the FPC antenna, and the radio frequency circuit of the FPC antenna is provided on the main board 20;

[0025] The main board 20, the FPC 30, and the conductive member 40 are received in the receiving cavity 11 of the housing 10, and the main board 20 and the FPC 30 are spaced apart;

[0026] The charging terminal 50 extends into the receiving cavity 11 and is electrically connected to the radio frequency circuit, and the conductive member 40 is electrically connected to the charging terminal 50;

[0027] The conductive member 40 can move to a first state or a second state. When the conductive member 40 moves to the first state, the conductive member 40 abuts against the FPC 30, and the radio frequency circuit on the main board 20 feeds power to the FPC 30 through the charging terminal 50 and the conductive member 40;

[0028] When the conductive member 40 moves to the second state, the conductive member 40 is spaced from the FPC 30, and the charging terminal 50 is used to transmit a charging signal.

[0029] It should be noted that the FPC 30 serves as the radiator of the FPC antenna, and the radio frequency circuit of the FPC antenna is implemented through the wiring and electronic devices on the main board 20. The radio frequency circuit includes at least a feeder. In addition, other devices such as a matching network, an antenna switch, and a filter may also be included, which are not specifically limited herein.

[0030] In some embodiments, the position of the conductive member 40 is adjustable. In the first state, the conductive member 40 moves to abut against the FPC 30. At this time, based on the electrical connection between the conductive member 40 and the charging terminal 50, and the electrical connection between the charging terminal 50 and the radio frequency circuit on the main board 20, the FPC 30 can be electrically connected to the radio frequency circuit on the main board 20 through the conductive member 40 and the charging terminal 50, so that the radio frequency path of the FPC antenna corresponding to the FPC 30 is connected, thereby starting the FPC antenna. For example, the feeder in the radio frequency circuit can feed power to the FPC 30 through the charging terminal 50 and the conductive member 40, so that the FPC 30 radiates antenna signals.

[0031] In some embodiments, as Figure 4 shown, the first state represents the position state where the conductive member 40 moves in the direction of the FPC 30 so that the conductive member 40 abuts against the FPC 30.

[0032] Different from the first state, in the second state, the conductive member 40 moves to be spaced from the FPC 30. At this time, the FPC 30 is disconnected from the radio frequency circuit on the main board 20, that is, the radio frequency path of the FPC antenna corresponding to the FPC 30 is disconnected, and the FPC antenna is turned off. At this time, the charging terminal 50 can be used to transmit a charging signal.

[0033] In some embodiments, the second state represents the position state where the conductive member 40 moves in the direction away from the FPC 30 so that the conductive member 40 is spaced from the FPC 30.

[0034] In some embodiments, the charging terminal 50 can be a pin (PIN foot) in the charging port of the wireless earphone.

[0035] For example: Assuming that the charging terminal 50 is the charging PIN-D terminal of the wireless earphone, at this time, in the first state, the charging PIN-D serves as the antenna interface of the FPC antenna; in the second state, the charging PIN-D can be used for normal charging.

[0036] In some embodiments, in order to achieve the switching of the conductive member 40 between the first state and the second state, it can be achieved by manually controlling the movement of the conductive member 40 or by controlling the movement of the conductive member 40 through a driving member.

[0037] As an alternative embodiment, a part of the conductive member 40 can extend outside the housing 10, so that the user can adjust the position of the conductive member 40 by operating the part of the conductive member 40 exposed outside the housing 10, so as to control the conductive member 40 to move to the position corresponding to the first state or the position corresponding to the second state.

[0038] As an alternative embodiment, an adjusting structure connected to the conductive member 40 can be provided, and the conductive member 40 extends outside the housing 10. In this way, the user can adjust the position of the conductive member 40 by operating the adjusting structure, so as to control the conductive member 40 to move to the position corresponding to the first state or the position corresponding to the second state.

[0039] As an alternative embodiment, a driving member capable of driving the movement of the conductive member 40 can be provided. The driving member can adopt any driving structure such as an electromagnetic driving structure or an electric driving structure. In this way, the user can drive the conductive member 40 to move by controlling the driving member or adjusting the relative position between the driving member and the conductive member 40, so as to control the conductive member 40 to move to the position corresponding to the first state or the position corresponding to the second state.

[0040] In the embodiment of the present application, the FPC 30 constitutes the radiator of the FPC antenna, and the radio frequency circuit of the FPC antenna is arranged on the main board 20. By electrically connecting the conductive member 40 to the charging terminal 50, and the charging terminal 50 is electrically connected to the radio frequency circuit on the main board 20. In this way, when the conductive member 40 moves to abut against the FPC 30, the excitation signal of the radio frequency circuit can be transmitted to the FPC 30 through the charging terminal 50 and the conductive member 40 in sequence, so as to realize the feeding function of the FPC antenna and enable the FPC antenna to radiate signals; and when the conductive member 40 moves to be spaced from the FPC 30, the electrical connection between the radio frequency circuit and the FPC 30 is disconnected. At this time, the charging terminal 50 is used to transmit charging signals. Thus, the charging terminal 50 and the conductive member 40 can be reused to realize the electrical connection between the FPC 30 and the radio frequency circuit on the main board 20. Compared with the related art, in which two elastic pieces need to be arranged on the main board to realize the electrical connection between the FPC and the radio frequency circuit on the main board, the charging terminal 50 and the conductive member 40 do not occupy extra space on the main board 20, and a smaller-sized main board 20 can meet the functional requirements of the wireless earphone, and thus the overall volume of the wireless earphone can be reduced.

[0041] As an alternative embodiment, such as Figure 5As shown, the wireless earphone 100 further includes a ceramic antenna 60. The ceramic antenna 60 is disposed on the main board 20, and the projection area of the FPC 30 on the main board 20 is spaced apart from the ceramic antenna 60.

[0042] In some embodiments, the FPC 30 is disposed in the space above the main board 20 and is spaced apart from the main board 20, and the orthographic projection area of the FPC 30 on the main board 20 is spaced apart from the area of the ceramic antenna 60 on the main board 20.

[0043] In some embodiments, the ceramic antenna 60 can be disposed at the head of the wireless earphone 100, that is, on the side close to the earphone receiver of the wireless earphone and far from the charging interface of the wireless earphone 100, and the FPC 30 can be disposed on the side of the wireless earphone 100 close to the charging interface. In this way, on the one hand, the mutual interference between the ceramic antenna 60 and the FPC antenna can be reduced; on the other hand, when the wireless earphone 100 is placed in the wireless earphone charging case, the shielding of the ceramic antenna 60 by the wireless earphone charging case can be reduced, thereby improving the communication reliability of the wireless earphone 100 in the scenario of being placed in the wireless earphone charging case.

[0044] In this embodiment, since the occupied space of the FPC antenna on the main board 20 is reduced, the main board 20 can leave space for deploying the ceramic antenna 60, and through the added ceramic antenna 60, the wireless communication function of the wireless earphone can be realized when the conductive member 40 slides to the second state. For example, during the charging of the wireless earphone or when it is electrically connected to a charging device, wireless communication is performed through the ceramic antenna 60.

[0045] It should be noted that the occupied space of the ceramic antenna 60 on the main board 20 is small. However, compared with the FPC antenna, the signal transmission efficiency of the ceramic antenna 60 is a bit worse. The ceramic antenna 60 can be used for short-term communication during the period when the FPC antenna is not activated, or the ceramic antenna 60 can be used to enhance the FPC antenna.

[0046] In some embodiments, when the conductive member 40 moves to the second state, the ceramic antenna 60 is activated; or,

[0047] When the conductive member 40 moves to the first state, the ceramic antenna 60 and the FPC antenna corresponding to the FPC 30 are activated simultaneously.

[0048] In one embodiment, the ceramic antenna 60 can be activated during the period when the FPC antenna is not working, that is, when the conductive member 40 is in the second state. At this time, when the FPC antenna cannot work, the short-range communication function of the wireless earphone can be realized through the ceramic antenna 60.

[0049] In another embodiment, during the operation of the FPC antenna, i.e., when the conductive member 40 is in the first state, the ceramic antenna 60 can be activated. At this time, the FPC antenna and the ceramic antenna 60 cooperate to jointly achieve the short-range communication function of the wireless earphone.

[0050] For example, the FPC antenna and the ceramic antenna 60 simultaneously transmit signals, and the two transmit different signals. In this way, dual-channel signal transmission can be achieved, resulting in higher signal transmission efficiency and stronger anti-interference ability. It can be applied to communication scenarios with high quality and low latency, such as game scenarios and listening to high-fidelity (HIFI) music, etc., which have high requirements for latency and signal transmission efficiency, and can also be used in scenarios with high requirements for anti-interference performance, such as walking long distances.

[0051] In this embodiment, by adding a ceramic antenna 60 to the main board 20, the communication reliability, signal transmission efficiency, anti-interference and other communication performances of the wireless earphone can be improved.

[0052] As an alternative embodiment, as Figure 7 shown, the FPC 30 includes a first segment AB, a second segment BC, and a third segment CD;

[0053] The first segment AB and the third segment CD extend in the same direction, the second segment BC is located between the first segment AB and the third segment CD, the first segment AB and the third segment CD are on the same side of the second segment BC, and the first segment AB and the third segment CD are electrically connected through the second segment BC;

[0054] In the case where the conductive member 40 slides to abut against the FPC 30, the positions of the FPC 30 in electrical contact with the conductive member 40 include one end of the first segment AB and / or the third segment CD facing away from the second segment BC.

[0055] In some embodiments, as Figure 7 shown, the FPC 30 has a U-shaped structure. The first end B of the second segment BC is connected end to end with the first segment AB, the second end C of the second segment BC is connected end to end with the third segment CD, the third segment CD extends in the same direction as the first segment AB, and the extending direction of the second segment BC is different from the extending directions of the first segment AB and the third segment CD.

[0056] In some embodiments, the extending direction of the second segment BC is perpendicular to the extending directions of the first segment AB and the third segment CD.

[0057] In this case, when the conductive member 40 slides to abut against the FPC 30, the positions of the FPC 30 in electrical contact with the conductive member 40 can be the first end A of the first segment AB and / or the second end D of the third segment CD.

[0058] It is worth noting that in this embodiment, the FPC 30 has a U-shaped structure, which can increase the electrical length of the FPC radiator, thereby enhancing the radiation range, frequency bandwidth, and radiation energy of the FPC.

[0059] In some embodiments, such as Figure 7 and Figure 8 shown, the first segment AB includes a main body portion 31, a connecting portion 32, and an extending portion 33. Among them, the main body portion 31 is attached to the inner wall of the receiving cavity 11. The connecting portion 32 is connected between the main body portion 31 and the extending portion 33, and one end of the connecting portion 32 facing away from the main body portion 31 bends and extends toward the main board 20 to reduce the distance between the extending portion 33 connected to one end of the connecting portion 32 facing away from the main body portion 31 and the main board 20.

[0060] In this way, on the one hand, the main body portion 31 is attached to the inner wall of the receiving cavity 11, which can increase the distance between the main body portion 31 and the main board 20, reduce the electromagnetic interference of the electronic components on the main board 20 to the main body portion 31, and reduce the occupation of the receiving space of the receiving cavity 11 by the main body portion 31; on the other hand, it can make the extending portion 33 close to the conductive member 40, and only a smaller-sized conductive member 40 is required to meet the requirement of switching between the first state and the second state of the conductive member 40, that is, the size of the conductive member 40 can be reduced.

[0061] It should be noted that the third segment CD has a similar structure to the first segment AB, and also includes a main body portion, a connecting portion, and an extending portion. In the embodiments of the present application, for the sake of convenience of description, the first segment AB is taken as an example for illustration. For the description of the main body portion, connecting portion, and extending portion on the third segment CD, reference can be made to the relevant description of the first segment AB, which will not be elaborated here.

[0062] In some embodiments, the electronic components with relatively large electromagnetic radiation or large-sized electronic components on the main board 20 can be arranged in the projection area of the main body portion 31 on the main board 20.

[0063] In this way, since the distance between the main board 20 and the main body portion 31 is relatively large, the electromagnetic radiation generated by the electronic components on the main board 20 can be reduced from interfering with the main body portion 31.

[0064] In some embodiments, a boss 13 can be provided in the receiving cavity of the housing 10 so that the connecting portion 32 and the extending portion 33 can extend along the surface of the boss 13, such as adhering the connecting portion 32 and the extending portion 33 to the surface of the boss 13.

[0065] In this way, the structural reliability of the connecting portion 32 and the extending portion 33 can be improved, and when the conductive member 40 abuts against the extending portion 33, large deformation of the connecting portion 32 and the extending portion 33 can be prevented.

[0066] In one embodiment, the first end A of the first segment AB is in electrical contact with the conductive member 40, or the second end D of the third segment CD is in electrical contact with the conductive member 40. At this time, the FPC antenna has only one feeding point, which is the contact point in electrical contact with the conductive member 40.

[0067] In another embodiment, there are two conductive members 40. The first end A of the first segment AB is in electrical contact with one of the conductive members 40, and the second end D of the third segment CD is in electrical contact with the other conductive member 40. At this time, the FPC antenna has two feeding points, which are the first end A of the first segment AB and the second end D of the third segment CD respectively.

[0068] For example: as Figure 5 shown, the number of conductive members 40 is two, which are the first conductive member 41 and the second conductive member 42 respectively; the number of charging terminals 50 is two, which are the first charging terminal 51 and the second charging terminal 52 respectively;

[0069] When the first conductive member 41 moves to the first state, the radio frequency circuit on the main board 20 feeds power to one end of the first segment AB facing away from the second segment BC through the first conductive member 41 and the first charging terminal 51; when the second conductive member 42 moves to the first state, the radio frequency circuit on the main board 20 also feeds power to one end of the third segment CD facing away from the second segment BC through the second conductive member 42 and the second charging terminal 52.

[0070] In this embodiment, two conductive members and two charging terminals can be set to correspond one by one, and the two sets of conductive members and charging terminals are distributed at opposite ends of the U-shaped PCB 30. Among them, each set of conductive members and charging terminals includes a conductive member and a charging terminal corresponding to the conductive member. In this way, the electrical connection between the radio frequency circuit on the main board 20 and the opposite ends of the U-shaped PCB 30 can be adjusted respectively, that is, the electrical connection between one end of the U-shaped PCB 30 and the radio frequency circuit is adjusted to be conducted or disconnected through a set of conductive members and charging terminals, and the electrical connection between the other end of the U-shaped PCB 30 and the radio frequency circuit is adjusted to be conducted or disconnected through the other set of conductive members and charging terminals, which can improve the flexibility of the electrical connection between the opposite ends of the U-shaped PCB 30 and the radio frequency circuit respectively.

[0071] As an alternative embodiment, as Figure 4 shown, the wireless earphone 100 further includes: an elastic member 70;

[0072] The elastic member 70 is arranged between the conductive member 40 and the charging terminal 50, and the elastic member 70 is in a compressed state. The FPC 30 is located on the side of the conductive member 40 facing away from the elastic member 70 and the charging terminal 50.

[0073] In some embodiments, when the conductive member 40 moves to the first state, the elastic member 70 is in a compressed state. In this way, when the wireless earphone vibrates or jolts, etc., the elastic member 70 can provide a restoring force towards the FPC 30 to the conductive member 40, so that the conductive member 40 can maintain a reliable abutment with the FPC 30.

[0074] In some embodiments, when the force exerted by the user or the driving member on the conductive member 40 away from the FPC 30 is greater than the restoring force of the elastic member 70, the conductive member 40 moves to the second state, and when the force exerted by the user or the driving member on the conductive member 40 away from the FPC 30 is small or reduced to be less than the restoring force of the elastic member 70, the elastic member 70 can drive the conductive member 40 to return to the first state.

[0075] In this embodiment, the conductive member 40 is default in the first state. For example, if the user does not manually operate the conductive member 40 to the second state, or the user does not control the conductive member 40 to the second state through the driving member, the conductive member 40 is under the restoring force of the elastic member 70 and is in the first state, which can increase the probability of electrical contact between the conductive member 40 and the FPC 30 and improve the reliability of the electrical connection between the conductive member 40 and the FPC 30.

[0076] As an alternative embodiment, as Figure 4 and Figure 10 shown, the charging terminal 50 is provided with a through hole 53, and the conductive member 40 passes through the through hole 53 and can move radially along the through hole 53.

[0077] In this embodiment, by providing the through hole 53 on the charging terminal 50 and the conductive member 40 passing through the through hole 53, during the process of the conductive member 40 switching between the first state and the second state, it does not hinder the relative movement of the conductive member 40 along the radial direction of the through hole 53 with respect to the charging terminal 50, and can keep the outer wall of the conductive member 40 in contact with the inner wall of the through hole 53. Thus, during the process of the conductive member 40 switching between the first state and the second state, the conductive member 40 can maintain an electrical connection with the charging terminal 50.

[0078] Of course, in addition to the way of providing the through hole 53 on the charging terminal 50 and the conductive member 40 passing through the through hole 53, other ways can also be adopted to realize the movable connection between the conductive member 40 and the charging terminal 50, and during the relative movement of the conductive member 40 with respect to the charging terminal 50, keep the conductive member 40 and the charging terminal 50 in electrical connection. For example: the conductive member 40 and the charging terminal 50 can be spaced apart, and the conductive member 40 and the charging terminal 50 are electrically connected through a flexible wire. Here, the movable connection method and the electrical connection method of the conductive member 40 to the charging terminal 50 are not specifically limited.

[0079] As an alternative embodiment, asFigure 9 and Figure 10 As shown in Figure 10 , the material of the conductive member 40 includes a magnetic material. When the wireless earphone 100 is matched and connected to the charging device 200, the position of the conductive member 40 corresponds to that of the magnetic member 201 in the charging device 200, and the conductive member 40 is attracted by the magnetic member 201 and moves to the second state.

[0080] In some embodiments, the magnetic material may include iron or a magnet. For example, the material of the conductive member 40 is iron and the magnetic member 201 is a magnet; or, the conductive member 40 and the magnetic member 201 are opposite-sex magnets.

[0081] In some embodiments, the charging device 200 may be a wireless earphone charging case or other charging devices, such as a wireless charging device. The type of the charging device 200 is not specifically limited herein.

[0082] Among them, the matching connection between the wireless earphone 100 and the charging device 200 may be that the charging terminal 50 on the wireless earphone 100 is matched and connected to the charging interface on the charging device 200. For example, the charging PIN-D pin on the wireless earphone 100 is connected to the PIN-D pin on the charging device 200.

[0083] In addition, the position correspondence between the conductive member 40 and the magnetic member 201 in the charging device 200 may be that the magnetic member 201 is located on the side of the conductive member 40 facing away from the FPC 30, so that the conductive member 40 is attracted by the magnetic member 201 and moves to the second state on the side away from the FPC 30.

[0084] In this embodiment, when the wireless earphone 100 is matched and connected to the charging device 200, the conductive member 40 can be driven by the magnetic member 201 to move to the second state. When the wireless earphone 100 is detached from the charging device 200, the conductive member 40 can return to the first state under the restoring force of the elastic member 70. In this way, during the matching connection between the wireless earphone 100 and the charging device 200, the magnetic member 201 can drive the conductive member 40 to disconnect the electrical connection between the FPC 30 and the charging terminal 50, so that the charging terminal 50 can be used to transmit a charging signal, enabling the charging device 200 to charge the wireless earphone 100; while during the disconnection between the wireless earphone 100 and the charging device 200, the magnetic member 201 can drive the conductive member 40 to connect the electrical connection between the FPC 30 and the charging terminal 50, thereby multiplexing the charging terminal 50 to transmit the FPC antenna signal in a non-charging scenario.

[0085] As an alternative embodiment, as Figure 6 shown, the conductive member 40 includes a conductive rod 43, a first bump 44, and a second bump 45;

[0086] The conductive rod 43 is located between the first bump 44 and the second bump 45, and the conductive rod 43 is fixedly connected to the first bump 44 and the second bump 45;

[0087] The conductive rod 43 penetrates through the through hole 53. The first bump 44 is located on the side of the charging terminal 50 facing the FPC 30, and the second bump 45 is located on the side of the charging terminal 50 facing away from the FPC 30;

[0088] The elastic member 70 is a spring surrounding the conductive rod 43. The first end of the spring is connected to the first bump 44, and the second end of the spring is connected to the charging terminal 50.

[0089] In some embodiments, the conductive rod 43 of the conductive member 40 penetrates through the through hole 53 on the charging terminal 50. At this time, the first bump 44 and the second bump 45 are respectively located on the side of the charging terminal 50 facing the FPC 30 and the side of the charging terminal 50 facing away from the FPC 30, and the spring is sleeved on the conductive rod 43 and clamped between the first bump 44 and the charging terminal 50.

[0090] It should be noted that when the number of the conductive members 40 is two, that is, including the first conductive member 41 and the second conductive member 42, the structures of the first conductive member 41 and the second conductive member 42 may be the same, and each includes a conductive rod 43, a first bump 44 and a second bump 45, which will not be elaborated here.

[0091] In this embodiment, the elastic force provided by the spring to the first bump 44 is directed towards the FPC 30, so that when the conductive member 40 is not operated by the user or not driven by the driving member, the spring can continuously push the first bump 44 to abut against the FPC 30.

[0092] In some embodiments, the elastic member 70 may be a metal conductive spring. In this way, when the conductive member 40 moves to the first state, there are two electrical connection paths between the radio frequency circuit on the main board 20 and the FPC 30. One path is radio frequency circuit - charging terminal 50 - conductive member 40 - FPC 30, and the other path is radio frequency circuit - charging terminal 50 - elastic member 70 - first bump 44 - FPC 30. In this way, the reliability of electrical signal transmission between the radio frequency circuit and the FPC 30 can also be improved through the metal conductive spring.

[0093] The embodiment of the present application also provides a charging device, such as Figure 9 and Figure 10 As shown, the charging device 200 is matched with the wireless earphone 100 in the foregoing embodiment of the present application, and a magnetic member 201 is provided in the charging device 200.

[0094] It should be noted that the charging device 200 further includes at least a charging interface 202 that matches the charging terminal 50 on the wireless earphone 100. At this time, the relative position of the magnetic member 201 and the charging interface 202 is designed based on the relative positions among the charging terminal 50, the conductive member 40, and the FPC 30 in the wireless earphone 100, so that when the charging device 200 is connected to the wireless earphone 100 in a matching manner, the charging terminal 50 is electrically connected to the charging interface 202, and the magnetic member 201 provides an attractive force away from the FPC 30 to the conductive member 40.

[0095] For example: As Figure 10 shown, assume that the charging device 200 is a wireless earphone charging case, which includes a case cover 203 and a case body 204. The case cover 203 is hinged to the case body 204 so that the case cover 203 can be opened and closed relative to the case body 204. The case body 204 has a receiving groove 2041. At this time, the charging interface 202 is provided at the bottom of the receiving groove 2041, and the magnetic member 201 is provided on the wall of the receiving groove 2041. In this way, when the wireless earphone 100 is inserted into the receiving groove 2041 of the case body 204 and is connected to the wireless earphone charging case in a matching manner, the charging terminal 50 at the bottom of the wireless earphone 100 is electrically connected to the charging interface 202, and the magnetic member 201 is located on the side of the conductive member 40 facing away from the FPC 30. The magnetic member 201 provides an attractive force away from the FPC 30 to the conductive member 40, so that the conductive member 40 moves to the second state.

[0096] In the embodiments of the present application, for the convenience of description, it is usually exemplified by taking the charging device 200 as a wireless earphone charging case, which does not constitute a specific limitation here.

[0097] Of course, the charging device 200 can be other charging devices other than the wireless earphone charging case. Based on the change in the structure of the charging device 200, the positions of the charging interface 202 and the magnetic member 201 on the charging device 200 can be adjusted accordingly, as long as it satisfies that when the charging terminal 50 is electrically connected to the charging interface 202, the magnetic member 201 provides an attractive force away from the FPC 30 to the conductive member 40. The structure of the charging device 200 is not specifically limited here.

[0098] In some embodiments, such as Figure 9As shown, the charging device 200 can be a wireless earphone charging case. When the wireless earphone charging case is opened, that is, when the case cover 203 is in the open state, if the wireless earphone 100 is inserted into the receiving groove 2041 of the case body 204, at this time, the conductive member 40 moves away from the FPC 30 towards the second state under the attraction of the magnetic member 201. During the opening of the wireless earphone charging case, the wireless earphone 100 can still perform wireless communication through the ceramic antenna 60. For example, in the scenario where the user opens the case cover 203 of the wireless earphone charging case and needs to connect the wireless earphone 100 to the mobile phone, the ceramic antenna 60 can be used to implement the short-range communication function between the wireless earphone 100 and the mobile phone.
