Referring to fig. 1 and fig. 2, in the circuit structure 100 according to the present disclosure, the circuit structure 100 includes a battery cell 11 and a conductive structure 12, the battery cell 11 includes a positive electrode tab 110 and a negative electrode tab 111, the positive electrode tab 110 and the negative electrode tab 111 are wound, and a portion of an outer side end 1110 of the negative electrode tab 111, which crosses over an outer side end 1100 of the positive electrode tab 110, is an extension 1111 along a winding direction of the negative electrode tab 111; the conductive structure 12 includes a first end portion 120 and a second end portion 121, at least one of the first end portion 120 and the second end portion 121 is connected to the positive electrode tab 110 or the negative electrode tab 111, and the conductive structure 12 is configured to attenuate an electromagnetic field generated by the extension portion 1111.

In the circuit structure 100 in the embodiment of the present application, the routing of the conductive structure 12 is simple, and at least one of the first end 120 and the second end 121 of the conductive structure 12 is connected to the positive plate 110 or the negative plate 111, which may include the case where one end of the conductive structure 12 is connected to the positive plate, and the other end is connected to the negative plate. The conductive structure 12 is configured to weaken the electromagnetic field generated by the extension section 1111, where mutual weakening may be understood as partial cancellation of the electromagnetic field generated by the conductive structure 12 and the electromagnetic field generated by the extension section 1111, or complete cancellation of the electromagnetic field generated by the conductive structure 12 and the electromagnetic field generated by the extension section 1111, so that the arrangement of the conductive structure 12 may reduce interference of the magnetic field radiation generated by the extension section 1111 to sensitive devices such as a speaker, and reduce current noise when the electronic device 10000 is used.

Referring to fig. 1, a battery 1000 is provided in an embodiment of the present disclosure, and the battery 1000 includes the circuit structure 100 provided in the embodiment of the present disclosure.

The circuit structure 100 that provides in this application is used to battery 1000 in this application embodiment, and the electromagnetic field that battery 1000 inside electric core 11 extends section 1111 part and produces can weaken each other with the electromagnetic field that conductive structure 12 produced, reaches the effect that reduces the external interference of magnetic field that electric core 11 produced, and it can be understood can effectively reduce the magnetic leakage of battery with circuit structure 100 encapsulation in battery 1000.

Referring to fig. 11, an electronic device 10000 is further provided in the embodiments of the present application, and the electronic device 10000 includes the circuit structure 100 provided in some embodiments of the present application.

In the electronic device 10000 of the embodiment of the present application, due to the application of the circuit structure 100 in the present application, under the condition that the electronic device 10000 works, the magnetic field provided by the conductive structure 12 can weaken each other with the magnetic field generated by the extension section 1111 portion of the electric core 11, for example, the magnetic field is partially offset or completely offset, so that the interference of the magnetic field radiation generated by the extension section 1111 portion to sensitive devices such as a speaker can be reduced, and further, the noise of the electronic device 10000 is effectively weakened or even eliminated, and the device performance and the user experience are improved.

With the development of technology, electronic products are widely applied to people's lives, and when small electronic products such as earphones are used, a built-in battery cell supplies power for a microphone, a loudspeaker, Bluetooth and the like. The built-in battery of the small electronic product is generally a small rechargeable battery (such as a steel shell battery or a soft package battery), the battery cell is generally made in a winding manner, and although the related art reduces the magnetic flux leakage of the battery by improving some winding manners, the magnetic flux leakage is still difficult to avoid. The applicant finds that, because the length of the negative electrode sheet is different from that of the positive electrode sheet, or the negative electrode sheet is wrapped on the outer side end of the positive electrode sheet for safety, the part of the outer side end of the negative electrode sheet, which is beyond the outer side end of the positive electrode sheet, may generate an electromagnetic field during use, thereby causing magnetic leakage.

However, in recent years, a TWS (True Wireless Stereo) bluetooth headset is widely used, which is compact such that a stacking distance of a battery and a speaker is close, and thus, the applicant has found that the above-mentioned small amount of leakage flux may also cause noise in the TWS headset. In particular, as the technology develops, most bluetooth headsets also have noise reduction function, and the noise is more obvious when the related functions of the wireless bluetooth headset are used and when a specific use scene such as loop connection and playing of specific format audio are used.

The applicant researches and discovers that the reasons for causing the noise comprise: in the bluetooth headset, the current of the battery may fluctuate due to the bluetooth chip transmitting the bluetooth signal, and based on the aforementioned magnetic flux leakage due to the design of the battery cell, when the current is changed, the electromagnetic field leaked from the battery is also changed, and the changed magnetic field interferes with sensitive devices such as a speaker to generate noise. Further research by the applicant has found that when the bluetooth chip performs a bluetooth connection, such as a bluetooth loop connection (e.g., Page paging phase), the current fluctuation is significant and the noise is more significant due to frequent ID packet transmission and waiting for reception.

Therefore, current fluctuation caused by the bluetooth module is easier to cause noise caused by interference of electromagnetic fields generated by a battery in an acoustic device such as a microphone and a loudspeaker connected with the bluetooth module. Through the careful research of the applicant, it is found that, for the noise problem caused by the winding battery, a reverse coil may be designed, and then, a certain arrangement mode is adopted, so that the coil can generate a magnetic field opposite to the battery core after being electrified, thereby canceling the magnetic field generated by the battery core to reduce the interference to the load, but the influence is limited by the space, and in order to ensure the good cancellation effect of the magnetic field generated by the battery core, the design requirement of the cancellation coil is higher and higher.

In view of this, the present application provides an improved circuit structure 100, at least one of the first end 120 and the second end 121 of the conductive structure 12 is connected to the positive electrode tab 110 or the negative electrode tab 111, and the conductive structure 12 is configured to generate an electromagnetic field that attenuates with the electromagnetic field generated by the extension section 1111, where the attenuation can be understood as canceling each other, and further, it may be that the electromagnetic field generated by conductive structure 12 and the electromagnetic field generated by epitaxial segment 1111 all cancel, alternatively, the electromagnetic field generated by the conductive structure 12 partially cancels the electromagnetic field generated by the epitaxial segment 1111, it can be seen that the conductive structure 12 provided in the present application is designed for magnetic field interference generated by the cathode plate extension segment, so that cancellation is more targeted, and the problem of noise generated by interference of the interference magnetic field generated by the extension segment 1111 on sensitive devices such as the horn 300 can be effectively solved.

Specifically, the electronic device 10000 in this application may be a mobile phone, a tablet computer, an audio player, a video player, a wired headset, a wireless bluetooth headset, such as a TWS headset, a sound box, or the like, and the battery 1000 of the electronic device 10000 in this application may be an autonomous battery. The load 200 included in the electronic device 10000 may include the bluetooth module 21, and the horn 300 may be considered as a part of the load 200, or may be understood as a part other than the load 200. The electronic device 10000 is applied with the circuit structure 100 in the present application, and the conductive structure 12 is adopted in the circuit structure 100 to weaken (including partially or completely canceling the interference electromagnetic field) the interference electromagnetic field generated by the extension section 1111, so as to suppress the influence of the interference magnetic field generated by the battery cell 11 due to the current change caused by the load 200 on the acoustoelectric devices such as the speaker 300, and further improve the problems of current noise generated by the speaker 300.

The electronic device 10000 mentioned below is explained by taking a TWS headset as an example.

It should be noted that, in some embodiments, the electronic device 1000 in the present application further includes a load 200, and the battery cell 11 is configured to supply power to the load. The load may include the bluetooth module 21, and the varying current may include a fluctuating current generated in the battery cell 21 due to the bluetooth module 21 receiving and transmitting a bluetooth signal when the battery cell 11 supplies power to the bluetooth module 21. It can be readily appreciated that the load included in the electronic device 1000 may be the same load as the load 200 involved in the circuit configuration 100.

The battery 1000 in this application may specifically be a winding type battery, for example, may be a button cell with a steel shell and a miniature soft package battery, the battery cell 11 may be located inside the battery 1000, the battery cell 11 may be a winding type battery cell 11, and when the battery 1000 normally works, based on the design of the battery cell, a magnetic field perpendicular to the top cover of the battery 1000 or the bottom shell of the battery 1000 may be generated by a current flowing through the battery cell 11.

As shown in fig. 2, the winding form and safety requirements of the battery cell 11 of fig. 2 determine that the outer end 1110 of the negative electrode tab 111 of the battery cell 11 passes over the outer end 1100 of the positive electrode tab 110. It can be understood that when the battery 1000 is operated, the alternating current generates a magnetic field on the closed coil, and then for the wound battery 1000, most of the magnetic fields generated by the positive electrode tab 110 and the negative electrode tab 111 of the battery cell 11 are cancelled out when the current of the battery 1000 fluctuates, and at this time, since the outer end 1110 of the negative electrode tab 111 passes over the outer end 1100 of the positive electrode tab 110, the crossed part is not cancelled out, and magnetic field radiation is generated outwards. That is, the magnetic field generated by the epitaxial segment 1111 when the battery cell 11 is supplied with a varying current is not cancelled, but the magnetic field radiation is generated.

Therefore, the circuit structure 100 in the battery 1000 is further designed with a conductive structure 12, and the conductive structure 12 may be connected in series with the battery cell 11. It should be noted that, in some embodiments, the battery cell 11 may be a battery cell of a soft package battery or a steel-shell battery, and/or the conductive structure 12 may be a wire, an FPC, or a circuit board; and/or, the conductive structure 12 may be disposed on a side of the battery cell 11 close to the horn 200, or the conductive structure 12 may be disposed between the battery 1000 and the horn 200.

It is understood that at least one of the first end 120 and the second end 121 of the conductive structure 12 may be connected to the positive electrode tab 110 or the negative electrode tab 111 of the battery cell 11, and further, at least one of the first end 120 and the second end 121 of the conductive structure 12 may be connected to the outer end 1100 of the positive electrode tab 110 or the outer end 1110 of the negative electrode tab 111. The conductive structure 12 may be implemented by a flexible circuit board, a printed circuit board, a copper wire winding, etc. When the cell 11 is energized, current is also present in the conductive structure 12. The conductive structure 12 may be a conductive coil of a certain radian, and the diameter, thickness, material, etc. of the conductive structure 12 may be determined comprehensively according to the intensity of the magnetic field radiation to be offset as required.

The conductive structure 12 is configured to weaken an electromagnetic field generated by the epitaxial section 1111, which may be understood as partially or completely canceling the electromagnetic field generated by the epitaxial section 1111, so that after the variable current generated by the load 200 (i.e. the load 200 connected to the circuit structure 100) included in the electronic device 10000 is transmitted to the electric core 11, for example, when the bluetooth module 21 operates, the electromagnetic field generated by the epitaxial section 1111 of the electric core 11 may be weakened by an electromagnetic field generated by the conductive structure 12, thereby reducing an influence of an interference magnetic field on devices such as a speaker 300 connected to the load 200, and further improving problems such as current noise generated by the speaker 300.

Referring to fig. 3-5, in some embodiments, the first end 120 corresponds to the outer end 1110 of the negative electrode tab 111, the second end 121 corresponds to the outer end 1100 of the positive electrode tab 110, and the current of the conductive structure 12 is configured to flow in a direction opposite to the direction of the current of the extension 1111 of the negative electrode tab 111.

In this way, the conductive structure 12 can be accurately aligned with the position of the extension section 1111 (certainly, a certain degree of deviation is allowed, and the deviation can be adjusted according to the actual need of noise control), and meanwhile, since the current of the conductive structure 12 is configured to be opposite to the current direction of the extension section 1111 of the negative plate 111, the conductive structure 12 can generate a magnetic field opposite to the magnetic field generated by the extension section 1111, so as to cancel the interference magnetic field generated by the extension section 1111, reduce the interference of the magnetic field on the acoustoelectric devices such as the loudspeaker 300 connected to the load 200, and reduce the current noise generated by the acoustoelectric devices.

It can be understood that the position of the first end 120 corresponds to the outer end 1110 of the negative electrode tab 111, and the position of the second end 121 corresponds to the outer end 1100 of the positive electrode tab 110, where the projection of the first end 120 and the projection of the outer end 1110 of the negative electrode tab 111 completely overlap in position, but may also be allowed to have a deviation within a certain error range, and may be determined according to actual design requirements.

For example, in some possible embodiments, the conductive structure 12 may be connected to the outer end 1100 of the positive electrode tab 110 or the outer end 1110 of the negative electrode tab 111 through two bonding pads, and since the bonding pads have a certain area, the end of the conductive structure 12 (e.g., the first end 120 or the second end 121) may be disposed at any position in the two bonding pads, or the length or the curvature of the first end 120 to the second end 121 may be adjusted by disposing the bonding pads at different positions, so as to meet the requirement of canceling the electromagnetic field of the epitaxial segment 1111. The above-mentioned establishment of connections at two ends (e.g., the first end 120 or the second end 121) of the conductive structure 12 on two pads and at different positions of the two pads can be considered to fall within the category of the above-mentioned "correspondence".

It can be understood that the position of the first end 120 corresponds to the outer end 1110 of the negative electrode tab 111, the position of the second end 121 corresponds to the outer end 1100 of the positive electrode tab 110, the position of the first end 120 may be set close to the outer end 1110 of the negative electrode tab 111, and the position of the second end 121 may be set close to the outer end 1100 of the positive electrode tab 110, so that a conductive structure 12 having a shape similar to that of the extension section 1111 may be formed between the first end 120 and the second end 121, and the current of the conductive structure 12 is opposite to that of the extension section 1111, so that the electromagnetic fields generated by the two may cancel each other (including partial cancellation or total cancellation).

It is understood that the position of the first end 120 corresponds to the outer end 1110 of the negative electrode tab 111, the position of the second end 121 corresponds to the outer end 1100 of the positive electrode tab 110, the position of the first end 120 may be set at the position of the outer end 1110 of the negative electrode tab 111 (for example, they overlap on different planes), the position of the second end 121 may be set at the position corresponding to the outer end 1100 of the positive electrode tab 110 (for example, the intersection point of the center of the winding circle of the battery cell 11 and the outer end 1100 of the positive electrode tab 110 connecting to the negative electrode tab 111, or it may be understood that the starting position of the extension section 1111 corresponds to the position of the second end 121, the ending position of the extension section 1111, that is, the position of the outer end 1110 of the negative electrode tab 111, corresponds to the first end 120, so that the projection of the conductive structure 12 on the plane of the extension section 1111 may be completely overlapped or partially overlapped with the extension section 1111, when fully overlapped, the cancelling effect of the magnetic field generated by the conductive structure 12 and the magnetic field generated by the epitaxial segment 1111 may be more pronounced.

It is understood that when the battery 1000 is in normal operation, the current flowing through the battery cell 11 will also flow through the conductive structure 12, and the current of the conductive structure 12 is configured to be opposite to the current direction of the extension portion 1111 of the negative electrode tab 111, in this case, the conductive structure 12 will generate a magnetic field opposite to the direction of the magnetic field generated by the battery cell 11, so that the magnetic field generated by the conductive structure 12 can cancel (partially cancel or completely cancel) the magnetic field radiation generated by the extension portion 1111.

In particular, fig. 2 also shows that the inner side end of the negative electrode tab 111 of the battery cell 11 also exceeds the inner side end of the positive electrode tab 110, but the exceeding part can be ignored due to the fact that the radian of the inner circle, i.e. the inner side, of the battery cell 11 is very small in practical situation; in addition, the current flowing through the inner ring of the battery cell 11 is also small, the current of the battery cell 11 gradually increases from the inner ring to the outer ring, and for the battery 1000, the magnetic field strength of the inner ring of the battery cell 11 is weak, so when designing the conductive structure 12, the specific structure of the conductive structure 12 can be designed only by considering that the external radiation magnetic field of the extension section 1111 portion is eliminated.

Referring to fig. 3, in some embodiments, the first end 120 is configured to be connected to the outer end 1110 of the negative electrode tab 111, and/or the second end 120 is configured to be connected to the outer end 1100 of the positive electrode tab 110.

As can be appreciated, the first end 120 is configured to connect to the outer end 1110 of the negative tab 111, and the second end 120 is configured to connect to the outer end 1100 of the positive tab 110; alternatively, the first end 120 is configured to be connected to the outer end 1110 of the negative electrode tab 111; alternatively, the second end 120 is configured to connect to the outboard end 1100 of the positive plate 110.

The first end 120 is connected to the outer end 1110 of the negative electrode tab 111, and may be connected by a bonding pad, a nickel tab, or the like; similarly, the second end 121 is connected to the outer end 1100 of the positive electrode sheet 110, and may be connected to the outer end by a bonding pad, a nickel sheet, or the like. Generally, the outer end 1100 of the positive tab 110 is connected to the positive tab and the outer end 1110 of the negative tab 111 is connected to the negative tab.

Referring to fig. 2 and 3, in some embodiments, in the case that the first end portion 120 is configured to be connected to the outer end portion 1110 of the negative electrode tab 111, the position of the second end portion 121 is set at the outer end portion 1100 of the positive electrode tab 110; alternatively, in the case where the second end 121 is configured to be connected to the outer end 1100 of the positive electrode tab 110, the position of the first end 120 is provided at the outer end 1110 of the negative electrode tab 111.

It is understood that in the case where the first end portion 120 is configured to be connected (either directly or indirectly, for example, by at least one of a tab, a nickel plate, a pad, etc.) to the outer end portion 1110 of the negative electrode tab 111, the position of the second end portion 121 is set at the outer end portion 1100 of the positive electrode tab 110, i.e., the position of the second end portion 121 corresponds to the outer end portion 1100 of the positive electrode tab 110; in the case where the second end 121 is configured to be connected to the outer end 1100 of the positive electrode tab 110, the position of the first end 120 is set at the outer end 1110 of the negative electrode tab 111, i.e., the position of the first end 120 corresponds to the outer end 1110 of the negative electrode tab 111.

It can be appreciated that since the outer end 1100 of the positive electrode tab 110 is closer to the end of the extension section 1111 near the outer end 1100 of the positive electrode tab 110, the position of the second end 121 is located at the outer end 1100 of the positive electrode tab 110, and a position including the second end 121 is located at the end of the extension section 1111 near the outer end 1100 of the positive electrode tab 110.

It is understood that the conductive structure 12 and the electrode tabs (the positive electrode tab 110 and the negative electrode tab 111) may not be in the same plane, and thus "corresponding" or "at" may also be understood as overlapping or partially overlapping in projection.

In this way, the arrangement of the conductive structure 12 can correspond to the position of the epitaxial segment 1111; meanwhile, as the current of the conductive structure 12 is configured to be opposite to the current direction of the extension section 1111 of the negative electrode tab 111, the conductive structure 12 can generate a magnetic field opposite to the magnetic field generated by the extension section 1111, so as to counteract the interference magnetic field generated by the extension section 1111 and prevent the interference magnetic field from affecting the acoustic-electric devices such as the loudspeaker 300 connected to the load and the like to generate current noise.

In addition, as shown in fig. 2, current flows from the negative electrode tab 111 to the positive electrode tab 110 in the battery cell 11, so that the current direction of the negative electrode tab 111 of the battery cell 11 is counterclockwise, and the current direction of the positive electrode tab 110 is clockwise, so that partial magnetic fields generated by the positive electrode tab 110 and the negative electrode tab 111 can be cancelled out, but the magnetic field generated by the extension section 1111 cannot be cancelled out by the design of the battery 1000 itself, and therefore, the electromagnetic field generated by the extension section 1111 needs to be further cancelled out (including partial cancellation or complete cancellation) by the conductive structure 12 designed in the present application. Then, as shown in fig. 3, the direction of the current flowing on the conductive structure 12 needs to be clockwise, i.e. in case the first end portion 120 is configured to connect with the outer side end portion 1110 of the negative electrode tab 111, the position of the second end portion 121 is set at the outer side end portion 1100 of the positive electrode tab 110; alternatively, as shown in fig. 4, when the second end 121 is configured to be connected to the outer end 1100 of the positive electrode tab 110, the position of the first end 120 is set at the outer end 1110 of the negative electrode tab 111, and the direction of the current flowing through the conductive structure 12 is still clockwise, and it should be noted that, in fig. 4, to distinguish the conductive structure 12 from the battery cell 11, the conductive structure 12 is shown in a dashed line form, and does not represent an actual structure.

Thus, as shown in fig. 2, the positive electrode and the negative electrode of the battery 1000 that are not provided with the conductive structure 12 are located on different sides, after the wire is wound through the conductive structure 12, as shown in fig. 3, under the condition that the battery cell 11 and the conductive structure 12 are combined as a module, the wire outlet position of the negative electrode of the battery 1000 is equivalent to being extended to the second end 121, so as to be located on the same side as the positive electrode of the battery 1000, of course, if the conductive structure 12 and the battery cell 11 are packaged inside the battery 1000, the positive electrode and the negative electrode that are finally led out from the battery 1000 can be located on the same side through the design, and therefore, subsequent lead-out wires can be conveniently connected with other elements. Certainly, as shown in fig. 4, when the battery cell 11 and the conductive structure 12 are combined to form a module, the outlet position of the positive electrode of the battery 1000 is extended to the first end 120, so as to be located on the same side as the negative electrode of the battery 1000, and if the conductive structure 12 and the battery cell 11 are packaged inside the battery 1000, the positive electrode and the negative electrode of the battery 1000, which are finally outlet, can be located on the same side through the design, so that the subsequent lead wires can be conveniently connected to other elements.

In some embodiments, the battery cell 11 is configured to supply power to the load 200, the first end 120 is configured to be connected to the outer end 1110 of the negative tab 111, the outer end 1100 of the positive tab 110 is configured to be connected to the current input terminal of the load 200, and the second end 121 is configured to be connected to the current output terminal of the load 200.

It is understood that the electronic device 10000 may be a headset, for example, a wireless bluetooth headset, and then the load 200 may include a bluetooth module 21, the battery cell 11 may be configured to supply power to the bluetooth module 21, in the case that the first end 120 is configured to be connected to the outer end 1110 of the negative plate 111, the outer end 1100 of the positive plate 110 is configured to be connected to a current input end of the load 200, and the second end 121 is configured to be connected to a current output end of the load 200. When the battery cell 11 and the conductive structure 12 are integrally formed, the outlet lines of the battery 1000 are located on the same side.

In some embodiments, the cell 11 is configured to supply power to the load 200, the second end 121 is configured to be connected to the outer end 1110 of the positive tab 110, the first end 120 is configured to be connected to a current input of the load 200, and the outer end 1110 of the negative tab 111 is configured to be connected to an output of the load 200.

It is understood that the electronic device 10000 may be a headset, for example, a wireless bluetooth headset, and then the load 200 may include a bluetooth module 21, the cell 11 may be configured to supply power to the bluetooth module 21, in the case that the second end 121 is configured to be connected to the outer end 1100 of the positive plate 110, the first end 120 is configured to be connected to a current input end of the load 200, and the outer end 1110 of the negative plate 111 is configured to be connected to an output end of the load 200.

Referring to fig. 5 and 6, in some embodiments, in a case where the first end 120 is configured to be connected to the outer end 1110 of the negative electrode tab 111, and the second end 121 is configured to be connected to the outer end 1100 of the positive electrode tab 110, the conductive structure 12 further includes a third end 122 and a fourth end 123, the first end 120 to the third end 122 form the first portion 124 of the conductive structure 12, the second end 121 to the fourth end 123 form the second portion 125 of the conductive structure 12, and the third end 122 and the fourth end 123 are disposed at an interval.

It will be appreciated that the spacing arrangement may be spaced a small distance apart to avoid causing the overall length of the conductive structure 12 to affect the magnetic field cancellation effect, and that the third end 122 and the fourth end 123 are not directly connected, for example looped through a load.

Referring to fig. 5 and 6, in some embodiments, the third end portion 122 and the fourth end portion 123 can be disposed at any position of the conductive structure 12; and/or the length of the first portion 124 and the length of the second portion 125 may be the same or different.

In this way, the combination of the negative electrode wire and the positive electrode wire of the conductive structure 12 can be realized, and if the conductive structure 12 and the battery cell 11 are packaged inside the battery, the positive and negative electrode wires of the battery 1000 can be led out at any position of the conductive structure 12; if the conductive structure 12 is located outside the battery 1000, it is equivalent to the positive and negative terminals of the battery 1000 can be led out at any position of the conductive structure 12.

It can be understood that, as shown in fig. 2, current flows from the negative electrode tab 111 to the positive electrode tab 110 inside the battery cell 11, so that the current direction of the negative electrode tab 111 of the battery cell 11 is counterclockwise, and the current direction of the positive electrode tab 110 is clockwise, so that partial magnetic fields generated by the positive electrode tab 110 and the negative electrode tab 111 can be cancelled out by each other, but the magnetic field generated by the extension section 1111 cannot be cancelled out by the design of the battery 1000 itself, and therefore, the electromagnetic field generated by the extension section 1111 needs to be further cancelled out (including partial cancellation or complete cancellation) by the conductive structure 12 designed in this application.

Then as shown in fig. 5 and 6, in order to counteract the magnetic field of the epitaxial segment 1111, the current flowing through the conductive structure 12 needs to be clockwise, and further for the convenience of connection to the load, the conductive structure 12 may include a first portion 124 and a second portion 125. Wherein the first portion 124 includes a first end 120 to a third end 122, the first end 120 may be configured to be electrically connected to the outer end 1110 of the negative electrode tab 111, so that the first portion 124 is electrically connected to the negative electrode tab 111 of the cell 11, and the routing of the first portion 124 is started from a position corresponding to the outer end 1111 of the negative electrode tab 111 of the cell 11 to the third end 122; the second portion 125 may include a second end 121 to a fourth end 123, and the second end 121 may be electrically connected to the outer end 1100 of the positive electrode tab 110, so that the second portion 125 is electrically connected to the positive electrode tab 110 of the battery cell 11, and the routing of the second portion 125 starts from a position corresponding to the outer end 1100 of the positive electrode tab 110 of the battery cell 11 to the fourth end 123.

Further, if the conductive structure 12 and the battery cell 11 are packaged in the battery 1000, positive and negative electrodes of the final outgoing line of the battery 1000 are also formed on the first portion 124 and the second portion 125, that is, the third end 122 and the fourth end 123 of the routing stop position of the first portion 124 and the second portion 125 are the final negative wiring position and the final positive wiring position of the battery 1000, respectively; the third end portion 122 and the fourth end portion 123 correspond to the extension of the negative terminal position and the positive terminal position of the battery 1000 if the conductive structure 12 is disposed outside the battery 1000.

As shown in fig. 5 and 6, in the case where the battery cells 11 are connected in series with the first portion 124 and the second portion 125, the third end 122 and the fourth end 123 can be located at any position of the conductive structure 12, or the length of the first portion 124 is the same as or different from the length of the second portion 125. As shown in fig. 5, the length of the first portion 124 is greater than the length of the second portion 125, and as shown in fig. 6, the length of the first portion 124 is less than the length of the second portion 125, the current flowing through the first portion 124 and the second portion 125 both flow clockwise.

It will be appreciated that the effect that the conductive structure 12 plays in the battery 1000 is the same regardless of where the third end portion 122 and the fourth end portion 124 are located in the conductive structure 12, i.e., the magnetic field cancellation effect generated by the conductive structure 12 is the same. In the above embodiments or implementations (including but not limited to any of fig. 3-6), no matter what connection method the conductive structure 12 is connected to the battery and the outgoing line method is connected to the load, the shape (e.g., length or arc) of the conductive structure 12 is set to correspond to the extension section 1111, so that the electromagnetic fields generated by the conductive structure 12 and the extension section 1111 may be mutually weakened (including partially or completely cancelled). And the shape design (e.g., length or arc) of the conductive structure 12 can be adjusted as needed to counteract the degree of magnetic field.

Referring to fig. 7-10, in some embodiments, the battery cell 11 is configured to supply power to the load 200, the third terminal 122 is configured to be connected to a current output terminal of the load 200, and the fourth terminal 123 is configured to be connected to a current input terminal of the load 200.

It is to be understood that, as mentioned above, in some embodiments, the first portion 124 and the second portion 125 are further formed with positive and negative electrodes of the final outgoing line of the battery 1000, that is, the third end 122 and the fourth end 123 of the routing stop positions of the first portion 124 and the second portion 125 are the final negative terminal position and the final positive terminal position of the battery 1000, respectively. In the case where the battery cell 11 supplies power to the load 200, such as the bluetooth module 21, the third end 122 is configured to be connected to a current output terminal of the load 200, the fourth end 123 is configured to be connected to a current input terminal of the load 200, and current flows from the first end to the load 200 through the fourth end 123, and then flows from the third end 122 to the load 200. The above-described connection may be direct connection or indirect connection, for example, connection via a connection structure. It will be appreciated that the first end portion 120 and the second end portion 121 are designated points on the conductive structure 12 in the embodiment of the present application, and such end portions may be integrally formed with the portions thereof to which they are connected, for example, the first end portion 120 and the second end portion 121 are respectively integrally formed with their respective connecting mechanisms, for example, a wire. Of course, the connection structure may be detachable from the connection structure, and is not limited herein.

Referring to fig. 7-10, in some embodiments, the third end 122 is configured to be connected to the current output terminal of the load 200 through the first connection structure 126, the fourth end 124 is configured to be connected to the current input terminal of the load 200 through the second connection structure 127, and the first connection structure 126 and the second connection structure 127 are overlapped. Thus, overlapping the first connection structure 126 and the second connection structure 127 can make the electromagnetic field generated by the first connection structure 126 and the electromagnetic field generated by the second connection structure 127 cancel each other out, thereby reducing or avoiding the problems of current noise and the like caused by the generation of interference magnetic fields to the load 200 or other modules such as the speaker 300 connected to the load 200.

Specifically, in a case that the electronic device 10000 is an earphone, fig. 7 and fig. 8 are schematic diagrams of internal wiring of a left earphone and a right earphone in one embodiment, respectively, and fig. 9 and fig. 10 are schematic diagrams of internal wiring of a left earphone and a right earphone in another embodiment, respectively. In fig. 7 and 8, the lengths of the first portion 124 and the second portion 125 are substantially the same, and in fig. 9 and 10, the track length of the first portion 124 is greater than the track length of the second portion 125.

In the two routing schemes shown in fig. 7-10, in the case that the first end 120 is configured to be connected to the outer end 1110 of the negative electrode tab 111, and the second end 121 is configured to be connected to the outer end 1100 of the positive electrode tab 110, then the conductive structure 12 further includes a third end 122 and a fourth end 123, and in the case that the third end 122 and the fourth end 123 are connected to the load 200, the internal routing needs to pass through the place covered by the horn 300 connected to the load 200.

At this time, in order to avoid generating a new interference magnetic field, in a case where the third end portion 122 is configured to be connected to the current output terminal of the load 200 through the first connection structure 126, and the fourth end portion 124 is configured to be connected to the current input terminal of the load 200 through the second connection structure 127, the first connection structure 126 and the second connection structure 127 need to overlap wires to cancel out electromagnetic fields generated by the first connection structure 126 and the second connection structure 127, respectively. In particular, positive bonding pad 114 shown in fig. 7-10 connected to positive tab 112 (shown in fig. 2), and negative bonding pad 115 connected to negative tab 113 (shown in fig. 2) may be used to connect conductive structure 12 or other external devices.

Referring to fig. 3-10, in some embodiments, the shape of the conductive structure 12 may correspond to the shape of the epitaxial segment 1111. In this way, by corresponding the shape of the extension section 1111 and the flow guiding structure 12, when the battery 1000 operates, the magnetic field generated by the flow guiding structure 12 and the magnetic field generated by the extension section 1111 are opposite in direction to cancel each other (partially cancel or completely cancel), so as to effectively suppress the interference magnetic field generated by the extension section 1111.

Specifically, the winding form of the battery cell 11 and the safety requirement as shown in fig. 2 determine that the outer end 1110 of the negative electrode tab 111 of the battery cell 11 passes over the outer end 1100 of the positive electrode tab 110, that is, the extension 1111 included in the negative electrode tab 111. It can be understood that when the battery 1000 operates, alternating current generates a magnetic field on the closed coil, and then for the wound battery 1000, most of the magnetic fields generated by the positive plate 110 and the negative plate 111 of the electric core 11 are cancelled out when the current of the battery 1000 fluctuates, and at this time, due to the existence of the extension section 1111 of the negative plate 111, the magnetic field generated by the extension section 1111 cannot be cancelled out, and the extension section 1111 generates magnetic field radiation to the outside.

In order to cancel the magnetic field radiation generated by the extending section 1111 to the outside, the conductive structure 12 is provided, and to ensure that the magnetic field generated by the conductive structure 12 and the magnetic field radiated by the extending section 1111 to the outside cancel each other as much as possible, the extending section 1111 and the conductive structure 12 may have corresponding shapes, and it should be noted that the corresponding shapes may be that the projection of the conductive structure 12 on the winding plane of the negative electrode tab 111 is partially or completely overlapped with the extending section 12.

Referring to fig. 3-10, in some embodiments, the conductive structure 12 may be configured as an arc-shaped structure having no more than one turn. Specifically, since the battery cell 11 is in a winding form, the extension section 1111 of the negative electrode tab 111 may have an arc-shaped structure; since the conductive structure 12 may correspond to the shape of the epitaxial segment 1111 in order to make the conductive structure 12 sufficiently cancel the magnetic field radiated from the epitaxial segment 1111, the conductive structure 12 may also be an arc-shaped structure. In particular, in order to ensure that the routing of the conductive structure 12 is simple, avoid the problems of incapability of routing, difficulty in routing due to multiple windings, and large on-resistance due to too long battery routing due to too many windings, and the like, and considering the length and shape of the extension section 1111, the conductive structure 12 may be configured as an arc-shaped structure with no more than one turn.

Further, referring to fig. 2 and 3, in some embodiments, the curvature of the conductive structure 12 is the same as or similar to the extension 1111, or the length of the conductive structure 12 is the same as or similar to the extension 1111. Specifically, the extension section 1111 corresponds to the shape of the flow guiding structure 12, and the curvature of the conductive structure 12 may be the same as or similar to the extension section 1111, or the length of the conductive structure 12 may be the same as or similar to the length of the extension section 1111. Thus, when the battery 1000 is in operation, the magnetic field generated by the current guiding structure 12 and the magnetic field generated by the extension section 1111 are opposite in direction and can cancel each other out, so as to effectively suppress the interference magnetic field generated by the extension section 1111.

In certain embodiments, the arc or length of the conductive structure 12 is configured to be determined according to the current sound emitted by the horn 300, wherein the cell 11 supplies power to the load 200, and the load 200 is connected to the horn 300.

It is understood that the load 200 may include the bluetooth module 21, the load 200 may be connected to the speaker 300, and the varying current caused by the load 200 during operation may cause the speaker 300 to be affected to generate current noise, so that the conductive structure 12 needs to cancel the disturbing magnetic field caused by the varying current in order to eliminate the current noise generated by the speaker 300, and therefore, for better cancellation effect, the radian or length of the conductive structure 12 is configured to be determined according to the current sound emitted by the speaker 300. For example, before leaving the factory, parameters such as the length, the radian, and the position of the conductive structure are adjusted by detecting the condition that the horn generates the current sound, and when the current sound is adjusted to a certain parameter so that the current sound meets the design requirement, for example, the current sound exceeds the range heard by the ears of a person or is not heard by a small majority of people, the conductive structure 12 under the parameter is determined to be the conductive structure meeting the requirement.

In particular, in some embodiments, the arc degree of the conductive structure 12 may also be adjusted according to the intensity of the radiation magnetic field generated by the extension section 1111, for example, if the intensity of the external radiation of the extension section 1111 is too large, the arc degree of the conductive structure 12 may be adjusted to be a larger arc degree, and if the intensity of the external radiation of the extension section 1111 is smaller, the arc degree of the conductive structure 12 may be correspondingly adjusted to be a smaller arc degree. In this case, the adjustment curvature may be a curvature of the conductive structure 12 extending from the first end 120 to the second end 121, while the first end 120 and the second end 121 are electrically connected to the outer end 1110 of the negative electrode tab 111 and the outer end 1100 positioned on the positive electrode tab 110.

Referring to fig. 2-6, in some embodiments, the battery cell 11 may include a positive tab 112 and a negative tab 113 (shown in fig. 2), and the outer end 1100 of the positive tab 110 is configured to be connected to the second end 121 through the positive tab 112; and/or the outer end 1110 of the negative electrode tab 111 is configured to be connected with the first end 120 through the negative electrode tab 113.

Referring to fig. 2, 7-10, further, in some embodiments, positive tab 112 may be connected to second end 121 via positive pad 114; and/or negative tab 113 may be connected to first end 120 via negative pad 115.

It is understood that the positive tab 112 may be connected to the second end 121 via the positive tab 112, and the outer end 1100 of the negative tab 111 may be connected to the first end 120 via the negative tab 113, or the outer end 1100 of the positive tab 110 may be connected to the second end 121 via the positive tab 112, or the outer end 1110 of the negative tab 111 may be connected to the first end 120 via the negative tab 113, or the like; and/or negative tab 113 may be connected to first end 120 via negative pad 115. As described above, since the pad has a certain area, the second end portion 121 may adjust the connection position on the positive pad 114 and the first end portion 120 may also adjust the connection position on the negative pad 115 in order to adjust parameters (such as length, arc, position, etc.) of the conductor structure 12.

At this time, the positive electrode pad 114 may be connected to the positive electrode tab 112 through a nickel plate, the negative electrode pad 115 may be connected to the negative electrode tab 113 through a nickel plate, or the positive electrode pad 114 and the negative electrode pad 115 may be directly connected to the positive electrode tab 112 and the negative electrode tab 113 without a nickel plate, or the first end portion 120 and/or the second end portion 121 may be directly connected to the negative electrode tab 113 and/or the positive electrode tab 112 without a connection of the negative electrode pad 115 and/or the positive electrode pad 114.

It is understood that, both the positive electrode pad 114 and the negative electrode pad 115 have a certain area, so that a more suitable connection position of the conductive structure 12 on the pad can be selected, so that the conductive structure 12 has a certain deviation from the position of the outer end 1110 of the positive electrode tab 110 or the negative electrode tab 111, but still belongs to the corresponding range.

In certain embodiments, the cell 11 and the conductive structure 12 are enclosed inside the battery 1000; alternatively, the cell 11 is enclosed inside the battery 1000, and the conductive structure 12 is disposed outside the battery 1000.

Referring to fig. 1, in some embodiments, the conductive structure 12 may be disposed on a side of the battery cell 11 close to the horn 300; alternatively, the conductive structure 12 may be disposed between the battery 1000 and the horn 300.

It is understood that the conductive structure 12 is disposed on a side of the battery cell 11 close to the horn 300, and may include a case where the battery cell 11 and the conductive structure 12 are packaged inside a battery; the conductive structure 12 is disposed between the battery 1000 and the horn 300, which may include a case where the conductive structure 12 is disposed outside the battery 1000.

As described above, by disposing the conductive structure 12 close to the horn 300, the conductive structure 12 can perform a better function of canceling the interference magnetic field, and noise generated by the horn 300 due to the interference magnetic field can be reduced or eliminated.

Specifically, in one embodiment, the electric core 11 of the built-in battery of the TWS earphone-like electronic device 10000 has a higher height, so that if the conductive structure 12 is disposed on the side of the electric core 11 away from the speaker 300, the conductive structure 12 is further away from the speaker 300, the magnetic field cancellation effect generated by the conductive structure 12 during the operation of the electronic device 10000 is weakened, which easily causes insufficient magnetic field cancellation, thereby affecting the noise reduction effect of the noise generated by the speaker 300, or in order to satisfy the noise control effect, an enlarged coil is needed, which causes difficulty in structure stacking, and also increases the weight and cost of the earphone.

Consequently, set up conducting structure 12 between electric core 11 and load 200 in this application to make conducting structure 12 nearer apart from loudspeaker 300's distance, avoid conducting structure 12 to produce reverse magnetic field to appear offsetting insufficient problem, in addition, conducting structure 12 can be more small and exquisite, and the magnetic field offsets the effect better.

Referring to fig. 1, in some embodiments, the conductive structure 12 is disposed on a plane parallel or substantially parallel to a plane formed by winding the negative electrode sheet 111. In this manner, the conductive structure 12 can control the stacking space while securing the attenuation effect on the magnetic field generated by the epitaxial segment 1111.

It is understood that in one embodiment, the cell 11 is a winding cell 11, and the conductive structure 12 may be arc-shaped. The plane where the conductive structure 12 is located is parallel or substantially parallel to the plane formed by winding the negative plate 111, for example, the conductive structure 12 is disposed on the top surface of the battery cell 11 away from the horn 300 and is disposed parallel to the top surface of the battery cell 11, or is disposed on the bottom surface of the battery cell 11 close to the horn 300 and is parallel to the bottom surface of the battery cell 11, so that the conductive structure 12 can be better disposed, the space occupied by the conductive structure 12 is reduced, the overall size of the device is reduced, and the interfering magnetic field generated by the portion, exceeding the outer end 1100 of the positive plate 110, of the outer end 1110 of the negative plate 111 of the battery cell 11 can be better offset, so that the complex anti-magnetic field interfering structure is avoided from being disposed inside the electronic device 10000, and the cost of the electronic device 10000 is reduced.

It is understood that when the conductive structure 12 is packaged inside the battery cell 11, it may be embedded in the battery cell 11, and the conductive structure 12 may be provided in a manner similar to offsetting the length of the negative electrode tab 111 of the battery cell 11 or supplementing the length of the positive electrode tab 110 of the battery cell 11.

In some embodiments, the conductive structure 12 is configured to generate a first electromagnetic field when a varying current is applied, and the electric core 11 is configured to generate a second electromagnetic field when a varying current is applied, where the first electromagnetic field and the second electromagnetic field weaken each other, and the second electromagnetic field includes the electromagnetic field generated by the extension 1111 when a varying current is applied.

It should be noted that the mutual weakening includes mutual cancellation, wherein the cancellation may be partial cancellation or complete cancellation.

Further, in some embodiments, the battery cell 11 supplies power to the load 200, the load 200 may include the bluetooth module 21, and the varying current may include a fluctuating current generated in the battery cell 11 due to the bluetooth module 21 receiving and transmitting a bluetooth signal when the battery cell 11 supplies power to the bluetooth module 21.

Specifically, the conductive structure 12 is connected in series with the battery cell 11, and the current of the conductive structure 12 may be configured to be opposite to the current direction of the extension 1111 of the negative electrode tab 111. The bluetooth module 21 may be connected to the speaker 300, the microphone, and the like, and it is understood that, in some embodiments, the electronic device 10000 may include an earphone, the earphone may be a bluetooth earphone, for example, a TWS bluetooth earphone, when the bluetooth module 21 operates, the electric core 11 may supply power to the bluetooth module 21, and at this time, the bluetooth module 21 may perform bluetooth signal transceiving so as to cause the electric core 11 to generate current fluctuation, that is, fluctuation current, that is, form variation current.

Therefore, when a variable current is applied to the battery cell 11, a first electromagnetic field is generated by the conductive structure 12, and when a variable current is applied to the battery cell 11, a second electromagnetic field is generated by the variable current being applied to the extension section 1111 formed by extending from a position on the negative pole piece 111 corresponding to the outer end 1100 of the positive pole piece 110 to the outer end 1110 of the negative pole piece 111, and at this time, the first electromagnetic field and the second electromagnetic field are opposite in direction, and the first electromagnetic field and the second electromagnetic field weaken each other.

In some embodiments, the fluctuating current caused by the bluetooth module 21 transceiving bluetooth signals may include: the fluctuating current generated by the cell 11 during the bluetooth connection. In this manner, the conductive structure 12 can prevent the electronic device 10000 from generating current noise due to current fluctuation of the battery 1000 caused when the external device is connected back using the bluetooth module 21.

Referring to fig. 11, specifically, the electronic device 10000 may include a bluetooth module 21, and the electronic device 10000 may be configured to wirelessly communicate with an external device through the bluetooth module 21. Thus, the wireless connection of the electronic device 10000 can be realized, which brings more convenient experience of using the electronic device 10000 for users,

specifically, the external device may be a mobile phone, a tablet computer, an audio player, or the like. In one implementation, the electronic device 10000 may be a TWS headset, and the electronic device 10000 is connected to the external device through the bluetooth module 21 in a wireless communication manner, so that the user can use the portable device without the trouble of winding wires of the headset, and the user experience is enhanced.

In one embodiment, the electronic device 10000 may be an earphone, further may be a wireless bluetooth earphone, the external device may be a mobile phone, and during the use of the electronic device 10000, the electronic device 10000 stores a connection record after establishing a connection with the external device in a pairing manner, and when the electronic device is disconnected from the external device and reconnected, for example, the cover of the bluetooth TWS earphone is automatically connected to the last connected device or reconnected over distance, it may be understood as a reconnection. Further, when the electronic device 10000 is in the loop back mode, current fluctuation with a frequency of 800Hz and 3.2KHz is generated, and the battery 1000 generates an alternating magnetic field with a frequency of 800Hz and 3.2 KHz. However, when the noise reduction mode is turned on so that the codec of the bluetooth module 21 needs to be turned on, since the acoustic-electric devices such as the speaker 300 and the microphone are connected to the bluetooth module 21, the speaker 300 and the bluetooth module 21 form a closed loop, and the speaker 300 vibrates under the action of an interference magnetic field (e.g., a first magnetic field) to generate noise, where the frequency of the noise is 800Hz, 3.2KHz and their multiples.

At this time, in order to avoid the generation of current noise, the battery 1000 of the electronic device 10000 is provided with the conductive structure 12, the conductive structure 12 and the negative plate 111 may form an induced magnetic field to cancel each other, that is, the battery cell 11 generates a first induced magnetic field, the conductive structure 12 generates a second induced magnetic field, and the first induced magnetic field and the second induced magnetic field weaken each other, so as to cancel (partially cancel or completely cancel) an interference magnetic field generated by the extension section 1111 of the negative electrode of the battery cell 11, and avoid the interference magnetic field from affecting the horn 300 to enable the electronic device 10000 to generate current noise.

In some embodiments, the bluetooth module 21 may include a bluetooth codec, and the varying current may include a fluctuating current caused by transmitting and receiving a file in the LHDC format when the battery cell 11 supplies power to the bluetooth module 21. In this way, the conductive structure 12 can prevent the electronic device 10000 from generating current noise when the electronic device 10000 transmits and receives a file in the LHDC format.

In order to avoid the generation of current noise, a conductive structure 12 is disposed in the battery 1000 of the electronic device 10000 or outside the battery 1000, and the conductive structure 12 and the negative plate 111 may form an induced magnetic field to cancel each other, that is, the battery cell 11 generates a first induced magnetic field, and the conductive structure 12 generates a second induced magnetic field, so as to cancel an interference magnetic field generated by the extension section 1111 of the negative electrode of the battery cell 11, and reduce the influence of the interference magnetic field on the horn 300, so that the electronic device 10000 generates current noise when receiving and transmitting documents in the LHDC format.

In some embodiments, the second electromagnetic field interfering with the horn 300 causes noise, and the frequencies of the varying current, the second electromagnetic field, and the noise are the same, and the frequencies include at least one of: 800Hz, 1.6KHz, 3.2KHz and multiples of any of these.
