[0056] Figure 14 A schematic diagram of the structure of a terminal used to implement the anti-interference method of the embodiments of this disclosure is shown. Detailed Implementation

[0057] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0058] Figure 1 This diagram illustrates a background illustration of an anti-interference method provided in an embodiment of the present disclosure, such as... Figure 1 As shown, the battery 10 includes a battery cell and a nickel plate 11. When current flows through the battery 10, current will flow through both the battery cell and the nickel plate 11. According to Ampere-Maxwell's law, a large magnetic field will be generated when current flows through, which will cause the battery output signal to include a large number of interference signals, resulting in a poor user experience.

[0059] Please see Figure 2 This provides a schematic diagram of a battery structure according to an embodiment of the present disclosure. Figure 2 As shown, the battery 10 includes a housing 22 and a battery cell. The battery cell is arranged around the housing 22, and an electrolyte is provided between the battery cells. The ends of the battery cells are connected to a first tab and a second tab. The battery 10 includes a first counteractor 21, wherein the first counteractor 21 is disposed on the outside of the housing 22, and the first counteractor 21 corresponds to the radiation zone in the radiation zone set.

[0060] According to some embodiments, the first tab and the second tab refer to the positive and negative tabs in the battery, and the first tab and the second tab do not specifically refer to a certain fixed tab. For example, when the first tab is the positive tab, the second tab can be, for example, the negative tab. For example, when the first tab is the negative tab, the second tab can be, for example, the positive tab.

[0061] In some embodiments, since the first tab and the second tab cannot be located at the same position at the end of the cell, there is a cell wire between the first tab and the second tab. Therefore, when the battery discharges, current flows through the cell wire between the first tab and the second tab, which also generates a radiation zone. Therefore, the first cancelling member 21 can be used to cancel this radiation zone.

[0062] According to some embodiments, an electrolyte is disposed between the battery cells. This electrolyte is not specifically defined as a single, fixed electrolyte. For example, the electrolyte may change when the type of electrolyte changes. For example, the electrolyte may change when the ionic conductivity of the electrolyte changes. The electrolyte may be a liquid electrolyte, and the electrolyte will change accordingly when the solvent in the electrolyte changes from ethylene carbonate (EC) to propylene carbonate (PC). The electrolyte may be a liquid electrolyte, and the electrolyte will change accordingly when the ionic conductivity changes from 10... -3 S / cm changes to l0 -2 When the S / cm ratio changes, the electrolyte will also change accordingly.

[0063] It is easy to understand that the first canceling element 21 does not specifically refer to a fixed canceling element. For example, when the area of ​​the first canceling element 21 changes, the first canceling element 21 can also change. For example, when the setting position of the first canceling element 21 changes, the first canceling element 21 can also change accordingly. When the magnetic field of the current generated by the battery changes, the first canceling element 21 can also change accordingly.

[0064] In some embodiments, see Figure 3 This provides a structural schematic diagram of a first offsetting element according to an embodiment of the present disclosure. Figure 3 As shown, the first counteracting member 21 includes a first portion 211 and a connecting member 212. The first portion 211 is disposed on the top surface of the housing, and the connecting member 212 is disposed on the side surface of the housing. The first portion 211 may be, for example, an arc-shaped plate wrapped around the top surface of the housing. The connecting member 212 may be, for example, a plate, and the connecting member 212 may be, for example, a cuboid plate.

[0065] Please see Figure 4 This provides a schematic diagram of a battery cell structure according to an embodiment of the present disclosure. Figure 4 As shown, the battery cell includes a positive electrode 41 and a negative electrode 42. The positive electrode 41 and the negative electrode 42 are wound together to form the battery cell 23 of the battery 10. When the battery is discharged, the current flows from the outside of the battery cell to the center of the battery cell.

[0066] According to some embodiments, the direction of the first current magnetic field corresponding to the first canceling element 21 is opposite to the direction of the second current magnetic field corresponding to the battery, that is, the direction of the magnetic field lines of the first current magnetic field is opposite to the direction of the magnetic field lines corresponding to the second current magnetic field, so that when the current magnetic field corresponding to the first canceling element 21 and the current magnetic field corresponding to the battery are superimposed, the current magnetic field corresponding to the current can be reduced.

[0067] In one or more embodiments of this disclosure, the battery includes a housing, a battery cell, the battery cell being disposed within the housing, an electrolyte being disposed between the battery cells, and the ends of the battery cells being connected to a first tab and a second tab. Since the battery includes a first counteractor 21, which can be disposed on the outside of the housing, and the first counteractor 21 corresponds to the radiation area in the radiation area set, the battery does not need to reduce interference signals by moving away from sensitive devices, nor does it need to add additional shielding materials. This can improve the battery's anti-interference capability while reducing battery costs and improving the user experience.

[0068] In some embodiments, the battery further includes a second counteractor 24 and a third counteractor 25, wherein the third counteractor 25 is disposed inside the housing and the second counteractor 24 is disposed outside the housing, and the third counteractor 25 is disposed along the cross-sectional direction of the cell.

[0069] According to some embodiments, please refer to Figure 5 This provides a schematic diagram of a battery structure according to an embodiment of the present disclosure. Figure 5 As shown, the second counteractor 24 is disposed on the outside of the housing. The second counteractor 24 can be used to counteract the radiation generated when current flows through the positive electrode tab after welding, thereby improving the battery's anti-interference capability. The second counteractor 24 is not specifically a fixed counteractor. For example, when the battery's dimensions change, the area of ​​the second counteractor 24 changes, and thus the second counteractor 24 can also change. For example, when the placement position of the second counteractor 24 changes, the second counteractor 24 can also change accordingly. When the magnetic field generated by the battery changes, the second counteractor 24 can also change accordingly.

[0070] According to some embodiments, the first counteracting member 21 and the second counteracting member 24 are connected. The connection methods of the first counteracting member 21 and the second counteracting member 24 include, but are not limited to, splicing, coupling, and integral molding. Figure 5 As shown, the first offsetting element 21 and the second offsetting element 24 can be spliced ​​together. Please refer to [link / reference]. Figure 6 This provides a schematic diagram of a battery structure according to an embodiment of the present disclosure. Figure 6 As shown, the first counteractor 21 and the second counteractor 24 can be integrally formed.

[0071] In some embodiments, when the second counteractor 24 coincides with the positive electrode tab and the welding component of the positive electrode tab, the battery may only have the first counteractor 21 and the second counteractor 24.

[0072] According to some embodiments, please refer to Figure 7 This provides a schematic diagram of the internal structure of a battery according to an embodiment of the present disclosure. Figure 7As shown, the third counteractor 25 is disposed inside the housing and is arranged along the cross-sectional direction of the battery cell. The third counteractor 25 can be used to counteract the radiation generated when current flows through the second counteractor 24 and the positive electrode tab and the area of ​​the second counteractor 24 do not overlap, thereby improving the anti-interference capability of the battery 10.

[0073] According to some embodiments, the third canceling element 25 does not specifically refer to a fixed canceling element. For example, when the size information of the battery 10 changes, the area of ​​the third canceling element 25 changes, and the third canceling element 25 may also change. For example, when the size information of the battery 10 changes, the placement position of the third canceling element 25 may also change accordingly, and the third canceling element 25 may also change accordingly. When the magnetic field of the current generated by the battery 10 changes, the third canceling element 25 may also change accordingly.

[0074] In some embodiments, when the second cancelling element 24 does not coincide with the positive electrode tab and the welding component of the positive electrode tab, the battery may include a first cancelling element 21, a second cancelling element 24, and a third cancelling element 25. The second cancelling element 24 can be used to cancel the radiation generated by the positive electrode tab, but since the second cancelling element 24 introduces new radiation when it does not coincide with the positive electrode tab and the welding component of the positive electrode tab, the third cancelling element 25 is used to cancel the radiation generated by the second cancelling element 24.

[0075] It is readily understood that the second cancelling element 24 and the third cancelling element 25 at least partially overlap in area. The current corresponding to the second cancelling element 24 is equal in magnitude and opposite in direction to the current corresponding to the third cancelling element 25. Please refer to [link / reference]. Figure 8 This provides an example schematic diagram illustrating the direction of current flow in an embodiment of this disclosure. For example... Figure 8 As shown, during battery discharge, the direction of the first current corresponding to the second cancelling element 24 can be, for example, A1, and the direction of the second current corresponding to the third cancelling element 24 can be, for example, A2. As can be seen from the figure, A1 and A2 are in opposite directions. The values ​​of the first and second currents are the same. According to Ampere-Maxwell's law, a magnetic field exists around a current. The direction of the magnetic field generated by the current can be determined, for example, by the current direction. When the directions of the first and second currents are opposite, the direction of the first magnetic field generated by the first current and the direction of the second magnetic field generated by the second current are also opposite. Therefore, in the overlapping area of ​​the second cancelling element 24 and the third cancelling element 25, the second and third current magnetic fields can be superimposed, allowing them to cancel each other out. This reduces the radiation generated by the battery and the interference signals generated by the second and third cancelling elements 24 and 25, thereby improving the battery's anti-interference capability.

[0076] According to some embodiments, please refer to Figure 9 This is a schematic diagram of the structure of an earphone provided in an embodiment of the present disclosure. Figure 9 As shown, this disclosure also provides an earphone 80, which includes a battery 10 and an audio device 81. The battery 10 includes a plurality of canceling elements. The plurality of canceling elements are disposed adjacent to the audio device 81, which can reduce interference signals in the audio signal output to the audio device, thereby improving the audio signal quality and enhancing the user experience.

[0077] The technical solutions of this disclosure can be applied to headphones, such as Bluetooth headphones. Bluetooth headphones utilize Bluetooth technology in hands-free headphones, freeing users from the constraints of wired connections and allowing for easy and convenient calls in various ways. Bluetooth headphones can be, for example, true wireless stereo (TWS) headphones, where the left and right earbuds operate independently without cable connection by wirelessly separating the left and right channels.

[0078] According to some embodiments, the audio device may be, for example, a speaker facing the ear. That is, the plurality of cancelling elements are arranged adjacent to the speaker facing the ear to improve the headphone's anti-interference capability and enhance the user experience.

[0079] The present disclosure will now be described in detail with reference to specific embodiments.

[0080] In the first embodiment, such as Figure 10 As shown, Figure 10 The diagram illustrates a flowchart of an anti-interference method provided in an embodiment of this disclosure. This method can be implemented using a computer program and can run on an anti-interference device. The computer program can be integrated into an application or run as a standalone utility application.

[0081] The executing entity of this disclosure embodiment can be a terminal, which may be a wireless device, including but not limited to: Bluetooth headsets, Bluetooth watches, Bluetooth glasses, etc. Specifically, the executing entity of this disclosure embodiment may be a TWS headset.

[0082] Specifically, the anti-interference method includes:

[0083] S101, Obtain the location information of the battery and audio device;

[0084] According to some embodiments, a battery refers to a component that can provide electrical power to an anti-interference device. The battery does not specifically refer to a particular, fixed battery. For example, the battery may change when its capacity changes. Similarly, the battery may change when its type changes. And even when its model changes.

[0085] In some embodiments, an audio device refers to a component in the headphones, excluding the battery, used for audio processing, and this audio device refers to a device located relative to the battery. The audio device does not specifically refer to a single, fixed component. For example, when the type of audio device changes, the audio device may also change accordingly.

[0086] As is easily understood, location information is used to represent the positional relationship between the battery and the audio device. This location information includes, but is not limited to, the distance between the battery and the audio device, their relative positions, etc. This location information does not refer to a specific fixed location. For example, when the position of the audio device changes, this location information may also change accordingly. Similarly, when the battery's placement changes, this location information may also change accordingly.

[0087] In some embodiments, when the TWS earphones perform an anti-interference method, the TWS earphones can obtain the location information of the battery and audio devices.

[0088] S102, Obtain the magnetic field parameters of the magnetic field corresponding to the current of the battery;

[0089] According to some embodiments, a current magnetic field refers to a magnetic field generated by a current flowing through a conductor in a closed circuit. In this embodiment, the current magnetic field refers to the magnetic field generated by a battery. This current magnetic field does not specifically refer to a fixed current magnetic field. For example, when the current corresponding to the battery changes, the current magnetic field may also change accordingly. For example, when the battery structure changes, the current magnetic field may also change accordingly. For example, when the structure of the positive and negative electrodes in the battery changes, the current magnetic field may also change accordingly.

[0090] It is easy to understand that magnetic field parameters refer to the parameters corresponding to the magnetic field of an electric current. These parameters include, but are not limited to, magnetic field radiation values, magnetic field strength values, etc. These magnetic field parameters are not specifically defined by a single fixed parameter; for example, when the type of parameter corresponding to a magnetic field parameter changes, the magnetic field parameter itself can also change accordingly. Similarly, when the numerical value of the parameter corresponding to a magnetic field parameter changes, the magnetic field parameter itself can also change accordingly.

[0091] In some embodiments, when the TWS earphones perform an anti-interference method, the TWS earphones can obtain the position information of the battery and the audio device, and the TWS earphones can obtain the magnetic field parameters corresponding to the current magnetic field of the battery.

[0092] Optionally, the execution order of steps S101 and S102 is not limited. That is, step S101 can be executed before step S102, step S102 can be executed before step S101, or steps S101 and S102 can be executed simultaneously.

[0093] S103, based on location information and magnetic field parameters, sets up a cancellation element between the battery and the audio device.

[0094] In some embodiments, a cancelling element refers to a device disposed between the battery and the audio device to cancel out radiation generated by the battery. This cancelling element is not specifically defined as a fixed cancelling element. For example, when the positional information between the audio device and the battery changes, the cancelling element will also change accordingly. For example, when the structure of the battery changes, the magnetic field parameters may also change accordingly, and the cancelling element may also change accordingly. When the dimensional information of the cancelling element changes, the cancelling element may also change accordingly.

[0095] When TWS earbuds implement anti-interference methods, they can obtain the position information of the battery and audio device, as well as the magnetic field parameters corresponding to the current magnetic field of the battery. Once the TWS earbuds obtain the position information and magnetic field parameters, they can set up a cancellation mechanism between the battery and the audio device based on these parameters.

[0096] In one or related embodiments of this disclosure, by obtaining the position information of the battery and the audio device, the magnetic field parameters of the corresponding current magnetic field of the battery can be obtained. Based on the position information and the magnetic field parameters, a cancellation device is set between the battery and the audio device. Therefore, the cancellation device can be used to cancel the interference signal corresponding to the first position information, reduce the influence of interference signals on the output signal of the battery, improve the quality of the output signal, improve the instructions of the signal received by the audio device, and improve the user experience.

[0097] Please see Figure 11 , Figure 11 This diagram illustrates a flowchart of an anti-interference method provided in an embodiment of this disclosure. Specifically:

[0098] S201, Obtain the location information of the battery and audio device;

[0099] The specific process is as described above and will not be repeated here.

[0100] In some embodiments, the battery can change accordingly when the electrolyte in the battery changes. Battery types include, but are not limited to, lithium batteries, lead-acid batteries, and dry cell batteries. Lithium batteries, in particular, are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution.

[0101] It is easy to understand that the audio device can be, for example, a speaker facing the ear. The headphones acquiring initial positional information about the battery and the audio source can be, for example, the headphones acquiring positional information about the battery and the speaker.

[0102] Optionally, the location information includes, but is not limited to, distance information and relative location information between the battery and the audio device. For example, the headphones can acquire distance information and relative location information between the battery and the speaker. Specifically, when the headphones acquire the location information of the battery and the speaker, they can acquire, for example, the distance information between the battery and the speaker.

[0103] S202, Obtain the current magnetic field corresponding to the battery;

[0104] According to some embodiments, the current magnetic field refers to the current magnetic field generated by the battery during discharge. The headphones can acquire the corresponding current magnetic field of the battery. Different current values ​​can generate different current magnetic fields, and different battery structures can also correspond to different current magnetic fields.

[0105] It is easy to understand that when the headphones perform the anti-interference method, the headphones can obtain the current magnetic field corresponding to the battery.

[0106] Optionally, step 203 is executed after step S202, and the execution order of steps S201 and 202 is not limited. For example, step S201 can be executed before steps S202 and S203, and steps S202 and S203 can also be executed before step S201. That is, the execution order can be steps S202, S203, and S201.

[0107] S203, simulates magnetic field interference of current magnetic field and obtains magnetic field parameters corresponding to current magnetic field.

[0108] According to some embodiments, simulation is the process of using a project model to translate uncertainties at a specific level into their impact on a target, represented at the level of the overall project simulation. Project simulation utilizes computer models and risk estimates at a specific level.

[0109] It is easy to understand that magnetic field interference simulation refers to simulations performed to reduce interference from the magnetic field of a current. This magnetic field interference simulation is not specific to any particular model. For example, the magnetic field interference simulation can change accordingly when the simulation tools used change.

[0110] In some embodiments, the headphones can simulate magnetic field interference to the electric current magnetic field and obtain magnetic field parameters.

[0111] S204, based on location information and magnetic field parameters, sets up a cancellation element between the battery and the audio device.

[0112] The specific process is as described above and will not be repeated here.

[0113] In some embodiments, the counteracting element may include at least one counteracting element. For example, the counteracting element may include multiple counteracting elements. The counteracting element may include, for example, a first counteracting element and a second counteracting element. When the second counteracting element coincides with the welding component of the positive electrode tab and the positive electrode tab, only the first counteracting element and the second counteracting element may be provided in the battery.

[0114] According to some embodiments, if the first tab in the battery does not coincide with the second counteractor, a third counteractor is provided in the cross-sectional direction of the cell.

[0115] The current corresponding to the second canceling element and the current corresponding to the third canceling element are equal in magnitude and opposite in direction.

[0116] The first tab can be, for example, a positive tab. If the positive tab in the battery does not coincide with the second canceling element, then a third canceling element is provided in the cross-sectional direction of the cell.

[0117] In some embodiments, when the second cancelling element does not coincide with the positive electrode tab and the welding component of the positive electrode tab, a first cancelling element, a second cancelling element, and a third cancelling element may be provided in the battery. The second cancelling element can be used to cancel the radiation generated by the positive electrode tab, but since the second cancelling element introduces new radiation when it does not coincide with the positive electrode tab and the welding component of the positive electrode tab, the third cancelling element is used to cancel the radiation generated by the second cancelling element.

[0118] In one or related embodiments of this disclosure, by obtaining the first position information of the battery and at least one first device, the first parameter of the magnetic field corresponding to the first current of the battery can be obtained. Based on the first position information and the first parameter, a first cancellation element is set between the battery and at least one first device. Therefore, the first cancellation element can be used to cancel the interference corresponding to the first position information, reducing the influence of interference signals on the output signal, improving the quality of the output signal, and enhancing the user experience. Secondly, by performing magnetic field interference simulation on the first current magnetic field to obtain the first parameter, the accuracy of obtaining the first parameter can be improved, as can the accuracy of setting the first cancellation element, thereby improving the battery's anti-interference capability.

[0119] The following are embodiments of the apparatus disclosed herein, which can be used to execute embodiments of the method disclosed herein. For details not disclosed in the apparatus embodiments of this disclosure, please refer to the embodiments of the method disclosed herein.

[0120] Please see Figure 12This illustration shows a schematic diagram of an anti-interference device provided in an exemplary embodiment of the present disclosure.
