[0034] To make the purpose, technical solutions and advantages of the present application clearer and more understandable, the following further details the present application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] It can be understood that terms such as "first" and "second" in the present application are only used to distinguish similar objects and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. It can be understood that "at least one" means one or more, and "a plurality" means two or more.

[0036] It can be understood that "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if there is an electrical signal or data transfer between the connected circuits, modules, units, etc.

[0037] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0038] Most of the smart earphones currently sold on the market are equipped with a dedicated charging box to achieve the charging function. After the smart earphones are placed in the charging box, the smart earphones will electrically connect their own charging contacts with the shrapnel on the charging box under the action of magnetic attraction or pressing to form a charging connection. During the use of the product, the charging contacts of the earphones are often in contact with human skin, and human sweat will connect the contacts. At this time, the earphones are charged in the box, and under the action of electrochemical corrosion, the positive electrode of the earphone charging shrapnel will produce oxidative corrosion. Over time, the anode shrapnel will cause corrosion and failure, and the earphones cannot be charged.

[0039] Taking TWS (True Wireless Stereo) as an example, in order to increase the corrosion resistance of the shrapnel, the existing technical solution will electroplate the charging shrapnel with expensive composite metals such as nickel, palladium nickel, gold and other coatings. However, during the use of TWS headphones, sweat will adhere to the positive and negative charging pads (contacts) on the headphones. When the headphones are charged in the box, the charging shrapnel will form electrochemical corrosion, forming the following corrosion process: (1) Anode process: The metal dissolves into the solution in the form of ions, and the same amount of electrons remain on the metal surface and migrate to the cathode area through the electronic conductor, that is, the anode undergoes an oxidation reaction. (2) Cathode process: The substance in the electrolyte solution that can accept electrons captures electrons from the metal cathode surface to generate new substances, that is, the cathode undergoes a reduction reaction. (3) Transfer of charge: The transfer of charge in metals relies on the flow of electrons from the anode to the cathode; in solutions, it relies on the electrical migration of ions. In this way, the entire battery system forms a loop through the cathode and cathode reactions and the flow of charge, and the anode process can continue, causing the metal to corrode. Figure 1 As shown in the figure, after a period of use, the corresponding contact position of the positive spring of the charging box will show corrosion marks. It can be understood that the cathode spring has no corrosion marks on the surface due to the reduction reaction.

[0040] As described above, in the prior art solution, the positive and negative electrodes of the spring are fixed during the use of the entire product, and the electrochemical corrosion effect will continue at the positive electrode. If used for a long time, the contact area of the positive spring will accumulate oxidative corrosion products, resulting in a failure to conduct and the product losing its function.

[0041] In the embodiment of the present application, by adding a rectifying circuit to the earphone, the earphone can be charged regardless of the positive and negative poles. A control circuit is added to the charging case and cooperates with the software control logic. Each time the earphone is inserted into the case and it is detected that the earphone is inserted, the software drives the control circuit to forcibly swap the positive and negative poles of the charging elastic contacts, and then charges the earphone. This logic control is cycled each time the earphone is inserted into the case, and after multiple repetitions, the corrosion effect of the electrochemical corrosion on the positive pole is evenly distributed to the two elastic contacts, thereby significantly extending the service life of the elastic contacts. In theory, the service life of the elastic contacts can be doubled. It should be noted that the beneficial effects or the technical problems solved by the embodiment of the present application are not limited to this one, and there may also be other implicit or related problems. For specific details, please refer to the description of the following embodiments.

[0042] The charging control method provided by the embodiment of the present application can be applied to an application environment as Figure 2 shown. Among them, the charging case 20 includes a case body and charging elastic contacts 22. The case body forms an internal space, and the charging elastic contacts 22 are arranged in the internal space and are electrically connected to the charging component. The charging component may include a charging circuit board (not shown in the figure), and the charging circuit board may include a flexible printed circuit (FPC). Optionally, the charging component may include a charging battery and a charging chip (Integrated Circuit Chip, IC) connected to the charging battery, and the battery capacity of the charging battery may be greater than the battery capacity in the audio device 10. Exemplarily, the case body has a receiving cavity, and the charging elastic contacts 22 are exposed in the receiving cavity. When the audio device 10 is installed in the charging case 20, the receiving cavity accommodates at least a part of the audio device 10, and the charging elastic contacts 22 are in contact with the charging contacts of the audio device 10.

[0043] It should be noted that the audio device 10 in the present application can be used in combination with an electronic device, and the communication method can be wireless communication methods such as Bluetooth, NFC (Near Field Communication), and WIFI; the electronic device may include devices such as mobile phones, tablet computers, laptop computers, and wearable devices that have a corresponding communication method with the audio device 10 and can perform data transmission; the audio device 10 may include devices such as wireless earphones, wireless speakers, and microphones that can perform audio input and output. Among them, the embodiment of the present application takes the audio device 10 as a wireless earphone as an example for analysis and explanation, but it should not be limited thereto.

[0044] Further, as Figure 2As shown, taking the wireless earphone as an example of the audio device 10, the wireless earphone may include a first earphone 11 and a second earphone 12. The structure of the first earphone 11 may be adapted to the left ear of the human body, and the structure of the second earphone 12 may be adapted to the right ear of the human body. The first earphone 11 and the second earphone 12 are structurally separated from each other. Optionally, the first earphone 11 and the second earphone 12 may be configured to be connected wirelessly, and the first earphone 11 and the second earphone 12 are identical in structure and mirror images of each other. Both the first earphone 11 and the second earphone 12 may be internally provided with a Bluetooth module for Bluetooth communication, or both the first earphone 11 and the second earphone 12 may be internally provided with other wireless communication modules for wireless communication.

[0045] Among them, the audio device 10 may include charging contacts, a circuit board, a speaker, and a battery (not shown in the figure). The speaker is electrically connected to the circuit board. The battery is connected to the circuit board to provide power for the operation of the wireless earphone. The charging contacts are electrically connected to the circuit board to charge the audio device 10; Exemplarily, the circuit board may include a charging circuit for charging the battery with the received current. The position and number of the charging contacts are not limited in this application. In some embodiments, the number of charging contacts may be two, and both are exposed on the outer surface of the housing of the audio device 10. The polarities of the two charging contacts are opposite, and they may respectively serve as the positive and negative charging electrodes of the audio device 10. Exemplarily, the charging contacts are made of a conductive material, for example, they may be made of a metal material, such as stainless steel, copper, alloy copper, etc. Of course, in other embodiments, the charging contacts may also be made of alloy materials such as rhodium ruthenium alloy electroplated on the surface of the metal material, so that the charging contacts have better wear resistance.

[0046] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These specific embodiments below may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0047] As Figure 3 shown, a charging case of an embodiment may include:

[0048] Charging spring pieces, which are used to contact the charging contacts of the audio device so that the charging case charges the audio device;

[0049] A control circuit 110, electrically connected to the charging spring pieces, for reversing the positive and negative polarities of the charging spring pieces during the charging process of the audio device.

[0050] Specifically, the charging case includes a case body and charging elastic pieces. The case body forms an internal space, and the charging elastic pieces are arranged in the internal space. Among them, the charging elastic pieces can be used to contact the charging contacts of the audio device, so that the charging case charges the audio device.

[0051] In the embodiment of the present application, the charging case further includes a control circuit 110. The control circuit 110 is electrically connected to the charging elastic pieces. Exemplarily, as Figure 3 shown, the control circuit 110 can also be electrically connected to the charging component 120 in the charging case. Further, taking the number of charging elastic pieces as 2 as an example, the control circuit 110 is used to reverse the positive and negative polarities of the charging elastic pieces during the process of charging the audio device. For example, reverse the positive and negative poles of 2 charging elastic pieces. By reversing the positive and negative poles of the charging elastic pieces, the control circuit evenly distributes the corrosion effect of electrochemical corrosion on the positive pole to the two charging elastic pieces, thereby significantly extending the service life of the charging elastic pieces and improving the service life of the charging case.

[0052] Regarding reversing the positive and negative polarities of the charging elastic pieces during the process of charging the audio device, exemplarily, it can be that the control circuit reverses the positive and negative polarities of the charging elastic pieces each time the audio device is charged, and repeats multiple times, so as to evenly distribute the corrosion effect of electrochemical corrosion on the positive pole to multiple charging elastic pieces.

[0053] In addition, regarding the control circuit reversing the positive and negative poles of the charging elastic pieces, it can be that the control circuit switches the connection relationship between the charging elastic pieces and the charging component, or the control circuit causes the polarities of the two charging elastic pieces to flip, so as to achieve the purpose of reversing the positive and negative poles of the charging elastic pieces. For example, through polarity flipping, the original positive and negative poles of the charging elastic pieces are interchanged, the charging elastic piece used as the positive pole in the charging case becomes the negative pole for reduction reaction, and the charging elastic piece used as the negative pole in the charging case becomes the positive pole for oxidation reaction, thereby avoiding the corrosion of the positive pole.

[0054] It can be understood that the above control circuit can adopt a control circuit combined with software control logic. For example, the software-driven control circuit forcibly reverses the positive and negative poles of the charging elastic pieces; the control circuit can also adopt other forms, and is not limited to the forms already mentioned in the above embodiments, as long as it can achieve the function of reversing the positive and negative poles of the charging elastic pieces.

[0055] Based on the embodiment of the present application above, a control circuit is added to the charging case, and during the process of charging the audio device, the function of reversing the positive and negative poles of the charging elastic pieces is realized, thereby significantly extending the service life of the charging elastic pieces. Theoretically, the service life of the charging elastic pieces can be doubled, and the service life of the charging case is improved.

[0056] In one of the embodiments, the control circuit reverses the positive and negative polarities of the charging elastic pieces when the audio device is put into the case.

[0057] Specifically, during the use of the audio device, the control circuit can reverse the positive and negative polarities of the charging spring contacts each time the audio device is inserted into the case. Herein, the audio device being inserted into the case may mean that the audio device is placed inside the accommodation cavity of the charging case.

[0058] Taking the audio device as a wireless earphone as an example, during the use of the earphone, each time the earphone is inserted into the case, the control circuit can reverse the positive and negative poles of the charging spring contacts to charge the earphone; exemplarily, each time the earphone is inserted into the case, the control circuit cycles the above logical control, so that each time the earphone is inserted into the case, the positive and negative poles of the charging spring contacts are reversed, thereby evenly distributing the corrosion effect of electrochemical corrosion to each charging spring contact, thus significantly extending the service life of the charging case.

[0059] In some embodiments, the control circuit reverses the positive and negative polarities of the charging spring contacts under the drive of a drive signal; the drive signal is generated by detecting that the audio device is in the state of being inserted into the case.

[0060] Specifically, for the control circuit added to the charging case, the control circuit can cooperate with the software control logic to implement the function of reversing the positive and negative poles of the charging spring contacts. Among them, when the software detects that the audio device is in the state of being inserted into the case, it can trigger the generation of a drive signal, and the drive signal is used to drive the control circuit to reverse the positive and negative polarities of the charging spring contacts. It can be understood that the audio device being in the state of being inserted into the case may mean that the audio device is placed inside the accommodation cavity of the charging case.

[0061] Taking the audio device as a wireless earphone as an example, each time the earphone is inserted into the case, after the software detects that the earphone is inserted into the case, the software can drive the control circuit to forcibly reverse the positive and negative poles of the charging spring contacts to charge the earphone, and this logical control is cycled each time the earphone is inserted into the case, so that each time the earphone is inserted into the case, the positive and negative poles of the charging spring contacts are reversed, so as to evenly distribute the corrosion effect of electrochemical corrosion to each charging spring contact, so as to significantly extend the service life of the charging spring contacts.

[0062] In a possible implementation, as Figure 4 shown, the control circuit of an embodiment may include a polarity inversion circuit; one end of the polarity inversion circuit is connected to the charging component of the charging case, and the other end of the polarity inversion circuit is connected to the charging spring contact.

[0063] Specifically, the charging component may include a charging battery and a charging chip connected to the charging battery. One end of the polarity inversion circuit is connected to the charging chip, and the other end of the polarity inversion circuit is connected to the charging spring contact. By providing the polarity inversion circuit in the embodiments of the present application, the polarity of the charging spring contact can be inverted, so as to achieve the purpose of reversing the positive and negative poles of the charging spring contact.

[0064] Exemplarily, the polarity inversion circuit may include a flip-flop and a switch component. Among them, the switch component is used to connect the charging spring piece to the charging component. The switching of the switch component is controlled by the output signal of the flip-flop, and the output signal of the flip-flop is controlled by a driving signal. The driving signal is generated by software when detecting that the audio device is in the boxed state, and the software can be run by the charging chip. It can be understood that the above control circuit can also adopt other forms, not limited to the forms already mentioned in the above embodiments, as long as it can achieve the function of reversing the positive and negative poles of the charging spring piece.

[0065] In the above charging case, through the control circuit electrically connected to the charging spring piece, every time the audio device is put into the box, the positive and negative polarities of the charging spring piece are reversed, so as to evenly distribute the corrosion effect of electrochemical corrosion to each charging spring piece, which can significantly extend the service life of the charging case.

[0066] In an exemplary embodiment, as Figure 5 shown, an audio device assembly is provided, including an audio device 10 and a charging case 20. The charging case 20 is used to accommodate the audio device 10; the charging spring piece of the charging case 20 is used to contact the charging contact of the audio device, so that the charging case 20 charges the audio device 10; wherein: the charging case 20 includes a control circuit, and the control circuit is electrically connected to the charging spring piece, and is used to reverse the positive and negative polarities of the charging spring piece during the process of charging the audio device.

[0067] Specifically, as Figure 5 shown, the charging case 20 may include a control circuit, and the control circuit is electrically connected to the charging spring piece, and is used to reverse the positive and negative polarities of the charging spring piece during the process of charging the audio device. Further, the control circuit is connected to the charging component. Exemplarily, the charging component can be used to connect to an external power supply.

[0068] In some embodiments, the control circuit reverses the positive and negative polarities of the charging spring piece when the audio device is put into the box.

[0069] It can be understood that for the specific structures and related functions of the various devices in the charging case, reference can be made to the relevant descriptions of the charging case in the previous text, and details will not be elaborated here.

[0070] In one of the embodiments, as Figure 6 shown, the audio device includes a rectifying circuit. The input end of the rectifying circuit is electrically connected to the charging contact, and the output end of the rectifying circuit is connected to the charging circuit of the audio device.

[0071] Specifically, the audio device can achieve that the charging contacts can receive the current from the charging case for charging regardless of the external positive and negative inputs through a rectifying circuit, and thus can cooperate with the charging case in the embodiments of the present application. The charging case can reverse the positive and negative polarities of the charging elastic pieces during the process of charging the audio device through a control circuit. Wherein, the input end of the rectifying circuit is electrically connected to the charging contacts, and the output end of the rectifying circuit is connected to the charging circuit of the audio device. The charging circuit can be used to charge the battery in the audio device with the received current.

[0072] In some embodiments, as Figure 7 shown, the rectifying circuit may include a bridge rectifying circuit.

[0073] Specifically, the rectifying circuit may be a bridge rectifying circuit, and the bridge rectifying circuit may include 4 diodes connected end to end: diode D1, diode D2, diode D3, and diode D4. Among them, the anode of diode D1 is connected to the cathode of diode D4, the anode of diode D2 is connected to the cathode of diode D3, the cathode of diode D1 is connected to the cathode of diode D2, and the anode of diode D3 and the anode of diode D4 are connected.

[0074] Further, the common connection point of diode D1 and diode D2 serves as the first output pole for outputting direct current, and the common connection point of diode D3 and diode D4 serves as the second output pole for outputting direct current. The load Rfz is connected between the first output pole and the second output pole.

[0075] Wherein, when E2 is in the positive half cycle, a forward voltage is applied to diode D1 and diode D3, and diode D1 and diode D3 conduct; a reverse voltage is applied to diode D2 and diode D4, and D2 and D4 are cut off. In the circuit, an energized loop of E2, diode D1, Rfz, and diode D3 is formed, and a half-wave rectified voltage with positive on the top and negative on the bottom is formed on the load Rfz; when e2 is in the negative half cycle, a forward voltage is applied to diode D2 and diode D4, and diode D2 and diode D4 conduct; a reverse voltage is applied to diode D1 and diode D3, and diode D1 and diode D3 are cut off. In the circuit, an energized loop of E2, diode D2, Rfz, and diode D4 is formed, and another half-wave rectified voltage with positive on the top and negative on the bottom is also formed on Rfz. Repeating this way, a full-wave rectified voltage is obtained on Rfz.

[0076] The embodiments of the present application can achieve that the charging contacts can receive the current from the charging case for charging regardless of the external positive and negative inputs through the bridge rectifying circuit, can match the charging case, and can receive the current from the charging case for charging.

[0077] In one of the embodiments, the audio device includes wireless earphones.

[0078] Specifically, the audio device in this application can be a wireless earphone; among them, a rectifying circuit can be added to the earphone to enable the earphone charging contacts to receive the current from the charging case for charging regardless of the external positive and negative input.

[0079] Further, as Figure 8 shown, a control circuit is added to the charging case in cooperation with software control logic. Each time the earphone is put into the case and the software detects the insertion, the software drives the control circuit to swap the positive and negative poles of the charging spring plate to charge the earphone. This logic control is cycled each time the earphone is put into the case, so that each time the earphone is put into the case, the positive and negative poles of the charging spring plate are swapped once. In the process of using the earphone in the embodiment of the present application, each time the earphone is put into the case, the positive and negative poles of the charging spring plate are swapped once, and after multiple reciprocations, the corrosion effect of electrochemical corrosion on the positive pole is evenly distributed to each charging spring plate (for example, two charging spring plates), thereby significantly extending the service life of the spring plate. Theoretically, the service life of the spring plate can be doubled.

[0080] In an exemplary embodiment, a charging control method is provided. Taking the charging case in Figure 2 as an example for illustration; it can be understood that this method can also be applied to an audio device component including an audio device and a charging case and is implemented through the interaction between the audio device and the charging case. The method includes the following steps:

[0081] When it is detected that the audio device is in the state of being put into the case, a driving signal is output; the driving signal is used to instruct the control circuit to swap the positive and negative polarities of the charging spring plate.

[0082] It can be understood that for the specific implementation process of each step in the charging control method, reference can be made to the relevant descriptions of the charging case and the audio device component in the previous text, which will not be elaborated here.

[0083] In the above charging control method, after detecting that the audio device is put into the case, the control circuit is driven to swap the positive and negative poles of the charging spring plate to charge the audio device. This logic control is cycled each time the audio device is put into the case, so that each time the audio device is put into the case, the positive and negative poles of the charging spring plate are swapped once. During the use of the frequency device, each time the audio device is put into the case, the positive and negative poles of the charging spring plate are swapped once, and after multiple reciprocations, the corrosion effect of electrochemical corrosion on the positive pole is evenly distributed to each charging spring plate, thereby significantly extending the service life of the spring plate. Theoretically, the service life of the spring plate can be doubled, and the service life of the charging case is improved.

[0084] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this document, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.

[0085] Based on the same inventive concept, an embodiment of the present application further provides a charging control device for implementing the charging control method described above. The solution provided by this device to solve the problem is similar to the solution described in the above method. Therefore, the specific limitations in one or more embodiments of the charging control device provided below can refer to the limitations on the charging control method in the above text, and will not be repeated here.
