Description

Technical Field

[0001] This application relates to the field of electronic musical instrument technology, and more specifically, to an electronic stringless guitar and a charging method thereon. Background Technology

[0002] Stringless electronic guitars can be charged using both a charging cable and a charging dock. However, if both the charging cable and the charging dock are connected simultaneously, they may cause voltage or current conflicts due to their different charging protocols or voltage / current outputs. This increases the risk of battery overheating and negatively impacts battery health and safety. Summary of the Invention

[0003] This application provides an electronic stringless guitar and a charging method to solve at least one of the aforementioned technical problems.

[0004] The electronic stringless guitar according to the embodiments of this application includes:

[0005] Battery;

[0006] Charging cable interface;

[0007] Charging dock interface;

[0008] A charging management module is provided, through which the charging cable interface and the charging dock interface are electrically connected to the battery.

[0009] The controller is electrically connected to the charging management module;

[0010] The controller is configured to, when a charging cable is connected to the charging cable interface, control the charging management module to charge the battery using the electrical energy transmitted by the charging cable, and when the charging cable interface is not connected to the charging cable but the charging dock interface is connected to the charging dock, use the electrical energy provided by the charging dock to charge the battery.

[0011] The electronic stringless guitar proposed in this application uses a controller to control the charging management module to select a single charging method to charge the battery. This facilitates the selection of an appropriate charging method, avoids voltage or current conflicts, and reduces the risk of device damage or battery overheating. In addition, the charging management module prioritizes charging via a charging cable, which helps improve charging efficiency and enhances safety.

[0012] In some embodiments, the controller is configured to, when the charging cable interface is connected to the charging cable and the charging dock interface is connected to the charging dock, control the charging of the battery using the electrical energy transmitted by the charging cable if the charging cable connection time is earlier than the charging dock connection time; and control the charging of the battery using the electrical energy transmitted by the charging dock interface if the charging cable connection time is later than the charging dock connection time.

[0013] Therefore, controlling the charging of the first connected charging device by timing sequence helps to avoid voltage or current conflicts.

[0014] In some embodiments, the controller is configured to, when a charging cable is connected to the charging cable interface, or when the charging dock interface is connected to the charging dock and the charging power of the charging cable interface is less than the charging power of the charging dock, control the use of electrical energy transmitted through the charging dock interface to charge the battery.

[0015] Therefore, choosing a higher-power charging device to charge an electronic stringless guitar can improve charging efficiency.

[0016] In some embodiments, the electronic stringless guitar further includes:

[0017] The fast charging chip is electrically connected to the charging cable interface and the charging management module, and the fast charging chip is electrically connected to the controller.

[0018] In this way, the fast charging chip can manage the battery's fast charging process, which is beneficial for the battery to charge safely and quickly.

[0019] In some embodiments, the electronic stringless guitar further includes:

[0020] A Bluetooth host is electrically connected to the controller and is used to connect to the charging dock's Bluetooth slave. The electronic stringless guitar is configured such that, based on Bluetooth pairing between the Bluetooth host and the charging dock, the charging management module uses the electrical energy transmitted from the charging dock to charge the battery.

[0021] In this way, pairing and identifying the Bluetooth host with the controller helps ensure that only certified devices can use the charging dock, preventing misuse or theft by others.

[0022] In some embodiments, the electronic stringless guitar further includes:

[0023] A battery management system, wherein the controller is electrically connected to the battery through the battery management system and is used to monitor the battery parameters, including battery voltage and battery current;

[0024] The controller is configured to receive charging electrical information sent by the charging dock via a Bluetooth host, and generate a charging termination signal based on the charging electrical information and the battery parameters, and send it to the charging dock via the Bluetooth host.

[0025] Therefore, monitoring battery parameters through a battery management system helps ensure battery safety and health.

[0026] Another embodiment of the charging method of this application is used for an electronic stringless guitar. The electronic stringless guitar includes a battery, a charging cable interface, a charging dock interface, a charging management module, and a controller. The charging cable interface and the charging dock interface are electrically connected to the battery through the charging management module, and the controller is electrically connected to the charging management module. The charging method includes:

[0027] Monitor the connection status of the charging cable;

[0028] When the charging cable interface is connected to the charging cable, the charging management module is controlled to charge the battery using the electrical energy transmitted by the charging cable.

[0029] When the charging cable is not connected to the charging cable interface but the charging dock interface is connected to the charging dock, the battery can be charged using the power provided by the charging dock.

[0030] Thus, the charging method provided in this application can select a single charging method to charge the battery, which helps to avoid voltage or current conflicts and reduce the risk of equipment damage or battery overheating.

[0031] In some embodiments, the charging method further includes:

[0032] When the charging cable is connected to the charging cable interface and the charging dock interface is connected to the charging dock, if the charging cable connection time is earlier than the charging dock connection time, the battery is charged using the electrical energy transmitted by the charging cable.

[0033] If the charging cable is connected later than the charging dock, the power transmitted through the charging dock interface is used to charge the battery.

[0034] Therefore, controlling the charging of the first connected charging device by timing sequence helps to avoid voltage or current conflicts.

[0035] In some embodiments, the charging method further includes:

[0036] When a charging cable is connected to the charging cable interface, if the charging dock interface is connected to the charging dock and the charging power of the charging cable interface is less than the charging power of the charging dock, the battery is charged using the electrical energy transmitted through the charging dock interface.

[0037] Therefore, choosing a higher-power charging device to charge an electronic stringless guitar can improve charging efficiency.

[0038] In some embodiments, charging the battery using the electrical energy provided by the charging dock includes:

[0039] Receive the pairing request from the charging dock and send device identity information to the charging dock;

[0040] After successful pairing, the control charging management module connects to the charging dock and sends a charging command to the charging dock, which then charges the battery.

[0041] In this way, the pairing mechanism enables the charging dock to authenticate the electronic stringless guitar and interact with charging commands, achieving intelligent control of the charging process, avoiding the risk of unauthorized devices being connected by mistake, and improving charging safety. At the same time, automated pairing and command sending simplify the user's operation steps, allowing users to complete the charging connection without manual settings, thus optimizing the user experience.

[0042] In some embodiments, the electronic stringless guitar further includes a battery management system, and the charging method further includes:

[0043] Get battery parameters;

[0044] The charging electrical information sent by the charging dock is obtained, and a charging termination signal is generated based on the charging electrical information and the battery parameters. The charging termination signal is sent to the charging dock, and the charging dock terminates the charging.

[0045] In this way, by monitoring battery parameters (such as voltage and current) in real time through the battery management system and combining this with charging electrical information (such as output power and charging status) fed back from the charging dock, dynamic and precise control of the charging process is achieved. When a fully charged battery or an abnormal charging condition is detected, a termination signal can be generated and sent to the charging dock in a timely manner, effectively preventing risks such as overcharging and overcurrent, and extending battery life. At the same time, this mechanism allows the charging process to adapt to the power supply capabilities of different charging docks (such as fast charging or normal charging), improving charging compatibility and efficiency.

[0061] Stringless electronic guitars can be charged using both a charging cable and a charging dock. However, if both the charging cable and the charging dock are connected simultaneously, they may cause voltage or current conflicts due to their different charging protocols or voltage / current outputs. This increases the risk of battery overheating and negatively impacts battery health and safety.

[0062] Please see Figure 1The electronic stringless guitar 10 of this application includes a battery 11, a charging cable interface 12, a charging dock interface 13, a charging management module 14, and a controller 15. The charging cable interface 12 and the charging dock interface 13 are electrically connected to the battery 11 through the charging management module 14. The controller 15 is configured to control the charging management module 14 to charge the battery 11 using the electrical energy transmitted by the charging cable 30 when the charging cable interface 12 is connected to the charging cable 30, and to charge the battery 11 using the electrical energy provided by the charging dock 20 when the charging cable interface 12 is not connected to the charging cable 30 but the charging dock interface 13 is connected to the charging dock 20. In all embodiments of this application, the situation where the charging cable interface 12 is connected to the charging cable 30 refers to the situation where the charging cable interface 12 is connected to the charging cable 30, and the charging cable 30 is connected to the charging head and plugged into a power socket. For the sake of brevity, this will not be described further.

[0063] The electronic stringless guitar 10 proposed in this application, by setting up a charging management module 14 and selecting a single charging method to charge the battery 11 through the charging management module 14, is conducive to selecting an appropriate charging method, avoiding voltage or current conflicts, reducing the risk of equipment damage or battery 11 overheating. In addition, the charging management module 14 prioritizes charging with the charging cable 30, which is conducive to improving charging efficiency and safety.

[0064] Specifically, charging using the charging cable 30 and charging using the charging dock 20 typically employs different charging protocols (such as fast charging protocols and wireless charging protocols). Simultaneous use may lead to voltage or current conflicts, exceeding the design limits of the device's battery 11 or charging circuit, causing the battery 11 to overheat, bulge, or even explode. Furthermore, simultaneous charging will superimpose the current load, potentially overloading the socket, charger, or internal circuitry of the device, increasing the risk of short circuits, sparks, and even fires. Therefore, in this embodiment, the charging management module 14 is used to select between the charging cable 30 and the charging dock 20 to charge the electronic stringless guitar 10, ensuring that only one charging method is always available for the electronic stringless guitar 10 during the charging process.

[0065] In this embodiment of the application, the charging cable interface 12 can be connected to the charging cable 30 for charging the battery 11 of the electronic stringless guitar 10. The charging cable interface 12 is usually a universal serial charging interface, such as a Type-C interface. Correspondingly, the charging cable 30 is usually a universal serial charging cable, such as a Type-C charging cable.

[0066] The charging dock interface 13 is used to connect to the charging dock 20 for charging the battery 11 of the electronic stringless guitar 10. The charging dock interface 13 and the charging dock 20 can be wired charging dock interface 13 and charging dock 20 connected by a plug, or wireless charging dock interface 13 and charging dock 20 connected by a coil.

[0067] In some embodiments, the controller 15 is configured to, when the charging cable interface 12 is connected to the charging cable 30 and the charging dock interface 13 is connected to the charging dock 20, control the charging cable 30 to be connected earlier than the charging dock 20 to charge the battery 11 using the electrical energy transmitted by the charging cable 30; and control the charging dock interface 13 to be connected later than the charging dock 20 to charge the battery 11 using the electrical energy transmitted by the charging cable 30.

[0068] Therefore, controlling the charging of the first connected charging device by timing sequence helps to avoid voltage or current conflicts.

[0069] Specifically, in some embodiments, the charging method of the electronic stringless guitar 10 can be selected according to the connection order of the charging cable 30 and the charging base 20. That is, the electronic stringless guitar 10 can be charged if the cable 30 is connected first, and the electronic stringless guitar 10 cannot be charged even if the other cable 30 is connected.

[0070] In some embodiments, the controller 15 is configured to charge the battery 11 using the electrical energy transmitted through the charging dock interface 13 when the charging cable interface 12 is connected to the charging cable 30, such as when the charging dock interface 13 is connected to the charging dock 20, and the charging power of the charging cable 20 is less than the charging power of the charging dock 20.

[0071] Therefore, choosing a higher-power charging device to charge the electronic stringless guitar 10 will help improve charging efficiency.

[0072] Specifically, in some embodiments, when both the charging cable 30 and the charging base 20 are connected to the electronic stringless guitar 10, the charging method can be selected by determining which charging method has the highest power. That is, regardless of the order of connection, only the one with the higher power is selected to charge the electronic stringless guitar. Alternatively, the electronic stringless guitar 10 can be charged first by selecting the one connected first, and then, after a preset change condition is met, the one with the higher power is selected to charge the electronic stringless guitar 10. The preset change condition may be that the charging time exceeds a preset time or the battery level exceeds a preset value.

[0073] Please see Figure 1 In some embodiments, the electronic stringless guitar 10 also includes a fast charging chip 16, the charging cable interface 12 is electrically connected to the charging management module 14 through the fast charging chip 16, and the fast charging chip 16 is electrically connected to the controller 15.

[0074] The controller 15 can be configured to send a command to the fast charging chip 16 to reduce the charging power or even stop charging when the battery temperature exceeds a preset temperature.

[0075] In this way, the fast charging chip 16 can manage the fast charging process of the battery 11, which is beneficial to the safe and fast charging of the battery 11.

[0076] Specifically, the fast charging chip 16 is an integrated circuit that combines a control unit, a power management unit, and a communication interface. By supporting multiple fast charging protocols such as USB PD, QC, and PPS, it enables efficient and secure communication between the device and the charger. Its core functions include dynamic adjustment of charging current / voltage, encrypted communication, temperature protection, and multi-protocol compatibility.

[0077] In this embodiment, the fast charging chip 16 is connected to the battery 11 through the charging management module 14, which can effectively improve charging efficiency. At the same time, the fast charging chip 16 can also be compatible with the different charging protocols of the charging cable 30 and the charging dock 20 and make dynamic adjustments.

[0078] In some embodiments, the fast charging chip 16 can also monitor voltage / current in real time and has overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP) and short circuit protection to prevent the battery 11 from being overcharged or overheated.

[0079] Please see Figure 1 In some embodiments, the electronic stringless guitar 10 also includes a Bluetooth host 18, which is electrically connected to the controller 15 and is used to connect to the charging dock Bluetooth slave 22 of the charging dock 20. The electronic stringless guitar 10 is configured such that, based on the Bluetooth connection between the Bluetooth host 18 and the charging dock 20, the charging management module 14 uses the power provided by the charging dock 20 to charge the battery 11.

[0080] Thus, pairing and identification between the Bluetooth host 18 and the controller 15 helps ensure that only certified devices can use the charging dock 20, preventing misuse or theft by others.

[0081] Specifically, in this embodiment, the electronic stringless guitar 10 is equipped with a Bluetooth host 18, and the electronic stringless guitar 10 needs to be connected to the charging dock 20 via Bluetooth before it can be charged.

[0082] Please see Figure 2Furthermore, in this embodiment, the charging dock 20 for charging the electronic wireless guitar 10 includes a charging dock master controller 21 and a charging dock Bluetooth slave 22, a parameter detection module 23, an output control module 24, and a charging dock output terminal 25, all electrically connected to the charging dock master controller 21. The charging dock master controller 21 controls the communication between the charging dock Bluetooth slave 22 and the Bluetooth host 18 inside the electronic stringless guitar 10, and the charging process of the electronic stringless guitar 10. The charging dock Bluetooth slave 22 communicates with the Bluetooth host 18 inside the electronic stringless guitar 10 to achieve automatic pairing and identification. The parameter detection module 23 detects the power parameters input to the charging dock 20 to ensure charging safety and efficiency. The output control module 24 controls the power output of the charging dock 20, adjusting it according to the charging needs and status of the electronic stringless guitar 10. The charging dock output terminal 25 connects to the charging dock interface 13 of the electronic stringless guitar 10 to charge the electronic stringless guitar 10.

[0083] Please see Figure 1 In some embodiments, the electronic stringless guitar 10 also includes a battery management system 17, through which the controller 15 is electrically connected to the battery 11.

[0084] The battery management system 17 is used to monitor the battery parameters of the battery 11, including battery voltage, battery current, temperature, capacity, and number of charge / discharge cycles.

[0085] The controller 15 can be used to detect the power level of the battery 11 through the battery management system 17, and when the power level of the battery 11 is less than a set value (e.g., 100%, 80%, etc.), control the charging management module 14 to connect the charging cable interface 12 or the charging dock interface 13 to charge the battery 11.

[0086] This can prevent overcharging of Battery 11, which could affect its performance or even cause potential hazards.

[0087] Specifically, in this embodiment, the controller 15 can monitor the status of the battery 11 in real time through the battery management system 17 to avoid sudden power outages due to insufficient power and improve device reliability. At the same time, timely reminders about the remaining power level can prevent deep discharge of the battery 11 and extend its cycle life (lithium batteries have the longest charge-discharge life in the 20%–80% range).

[0088] In some embodiments, the controller 15 issues a reminder signal when the battery 11 has less than 20% power. The electronic stringless guitar 10 also includes a reminder module electrically connected to the controller 15. The reminder module is used to receive the reminder signal and remind the user that the battery 11 has low power after receiving the reminder signal.

[0089] In some embodiments, the controller 15 is configured to receive charging electrical information sent by the charging dock 20 via the Bluetooth host 18, and generate a charging termination signal based on the charging electrical information and battery parameters, and send it to the charging dock 20 via the Bluetooth host 18.

[0090] In some embodiments, the electrical information may be electrical information such as charging dock current and charging dock voltage received by the Bluetooth host 18 and sent by the charging dock 20. The controller 15 compares the charging electrical information with the battery parameters to determine the validity of the battery parameters. If the difference between the charging electrical information and the battery parameters is within a preset difference value, the validity determination is passed. When the battery voltage is greater than a preset voltage value and the battery current is less than a preset current value, a charging termination signal is generated.

[0091] For example, the charging dock 20 sends a charging dock voltage of 15.98V and a charging dock current of 0.12mA to the Bluetooth host 18, while the controller 15 obtains battery parameters showing a battery voltage of 16V and a battery current of 0.11mA. The differences between the charging dock voltage and battery voltage, and between the charging dock current and battery current, are both within preset thresholds. In this case, the controller 15 determines that the battery parameters are valid. However, because the battery voltage is greater than a preset voltage value and the battery current is less than a preset current value, the controller 15 generates charging termination information. It should be noted that this example is for illustrative purposes only, aiming to make the solution easier to understand, and does not represent the actual use of the above values.

[0092] Thus, monitoring the battery parameters through the battery management system 17 helps ensure the safety and health of the battery 11.

[0093] Specifically, the Battery Management System (BMS) 17 is the core intelligent component of the battery 11. By integrating sensors, control algorithms and execution circuits, it performs real-time monitoring, precise control and optimized management of the battery 11. Its core objectives are to ensure the safety of the battery 11, extend the life of the battery 11, improve system efficiency, and ensure that the battery 11 operates stably under various operating conditions.

[0094] In this embodiment, the battery management system 17 assists the controller 15 in collecting various parameters of the battery 11 and monitoring the battery 11. Simultaneously, it can trigger protection circuits (such as fuses or relays) to cut off dangerous paths and prevent the accident from escalating when an anomaly is detected. Specifically, under normal circumstances, the error between charging electrical information and battery parameters is very small, and the battery parameters can be used as the standard. When the battery voltage is greater than a certain threshold and the battery current is less than a certain threshold for a preset duration, a charging termination signal is generated. When the error between the charging electrical information and battery parameters exceeds a preset difference, this is considered an abnormal state, and a charging termination signal is also generated.

[0095] In one embodiment, if the error between the charging electrical information and battery parameters exceeds a preset difference, the validity determination fails, and a charging termination signal with an abnormal state is generated and sent to the charging dock 20 via the Bluetooth host 18. Upon receiving the charging termination signal with an abnormal state, the charging dock 20 disconnects the charging of the electronic stringless guitar and issues an error message. If the charging cable interface 12 is connected to the charging cable 30 at this time, the control charging management module 14 uses the electrical energy transmitted through the charging cable 30 to charge the battery 11.

[0096] Please see Figure 1 and Figure 3 Another embodiment of the charging method of this application, used for an electronic stringless guitar 10, includes the following electrical method:

[0097] Step 01: Monitor the connection status of the charging cable;

[0098] Step 02: With the charging cable connected to the charging cable interface, the control charging management module uses the electrical energy transmitted through the charging cable to charge the battery;

[0099] Step 03: Charge the battery using the power provided by the charging dock when the charging cable is not connected to the charging dock interface but the charging dock interface is connected to the charging dock.

[0100] Thus, the charging method provided in this application can select a single charging method to charge the battery 11, which helps to avoid voltage or current conflicts and reduce the risk of equipment damage or battery 11 overheating.

[0101] Specifically, in some embodiments, steps 01, 02 and 03 can be implemented by the controller 15, or the charging management module 14 can be used to monitor the connection status of the charging cable 30; when the charging cable interface 12 is connected to the charging cable 30, the battery 11 is charged using the power provided by the charging cable 30; when the charging cable interface 12 is not connected to the charging cable 30 but the charging socket interface 13 is connected to the charging socket 20, the battery 11 is charged using the power provided by the charging socket 20.

[0102] Furthermore, in this embodiment of the application, when the battery 11's charge level is lower than a preset value, the charging management module 14 issues a reminder signal.

[0103] Specifically, in some embodiments, the preset value can be 20% of the battery 11's charge. That is, when the battery 11's charge is below 20% and it is not connected to the charging cable 30 and charging dock 20 for charging, a reminder signal will be issued to remind the user to charge the electronic stringless guitar 10 in time.

[0104] Please see Figure 1 and Figure 4In some embodiments, the electronic stringless guitar 10 further includes a controller 15 electrically connected to the battery 11. The controller 15 detects the battery level of the battery 11 and sends a first signal when the battery level is less than a set value (e.g., 100%, 80%, etc.) to control the charging management module 14 to start selecting the charging mode, thereby facilitating charging at any time. The controller 15 can continue to detect the first signal when it does not detect it.

[0105] Please see Figure 4 In some embodiments, the charging method further includes:

[0106] Step 04: When the charging cable is connected to the charging cable interface and the charging dock interface is connected to the charging dock, if the charging cable connection time is earlier than the charging dock connection time, control the use of the power transmitted by the charging cable to charge the battery.

[0107] Step 05: If the charging cable is connected later than the charging dock, control the charging to use the power transmitted from the charging dock interface to charge the battery.

[0108] Therefore, controlling the charging of the first connected charging device by timing sequence helps to avoid voltage or current conflicts.

[0109] Specifically, in some embodiments, when both the charging cable 30 and the charging base 20 are connected to the electronic stringless guitar 10, the charging method for the electronic stringless guitar 10 can be selected according to the connection order of the charging cable 30 and the charging base 20. That is, the electronic stringless guitar 10 can be charged if the cable 30 is connected first, and the electronic stringless guitar 10 cannot be charged even if the other cable 30 is connected.

[0110] Please see Figure 5 In some embodiments, the charging method further includes:

[0111] Step 06: When the charging cable is connected to the charging cable interface, or the charging dock interface is connected to the charging dock, and the charging power of the charging cable interface is less than or equal to the charging power of the charging dock, control the use of the electrical energy transmitted from the charging dock interface to charge the battery.

[0112] Therefore, choosing a higher-power charging device to charge an electronic stringless guitar can improve charging efficiency.

[0113] Specifically, in some embodiments, when both the charging cable 30 and the charging base 20 are connected to the electronic stringless guitar 10, the charging method can be selected by determining which charging method has the highest power. That is, regardless of the order of connection, only the one with the higher power is selected to charge the electronic stringless guitar.

[0114] Please see Figure 2 and Figure 6Furthermore, in this embodiment of the application, when the electronic stringless guitar 10 is charged via the charging dock 20, the charging dock 20 is also used to receive the first signal, and the charging method of the charging dock 20 includes:

[0115] Step 101: Obtain the pairing status between the electronic stringless guitar and the charging dock;

[0116] Step 102: When the electronic stringless guitar and the charging dock are being paired for the first time, the electronic stringless guitar and the charging dock will pair.

[0117] Step 103: When the electronic stringless guitar is not paired with the charging dock for the first time, the charging dock will automatically recognize the electronic stringless guitar;

[0118] Step 104: Determine whether the first signal has been received;

[0119] Step 105: When the first signal is received, turn on the charging dock output to charge the battery;

[0120] Step 106: When the first signal is not received, disconnect the output terminal of the charging dock.

[0121] Specifically, after the Bluetooth slave unit 22 of the charging dock successfully pairs with the Bluetooth host 18 inside the electronic stringless guitar 10, the charging dock master controller 21 can receive the first signal. The first signal can be transmitted from the Bluetooth host 18 to the Bluetooth slave unit 22 of the charging dock and then to the charging dock master controller 21. When the charging dock master controller 21 receives the first signal sent by the controller 15, it controls or connects the charging dock output terminal 25 through the output control module 24 to start charging, thereby realizing the charging of the electronic stringless guitar 10 through the charging dock 20. If the first signal is not received, the charging dock output terminal 25 is kept disconnected to avoid potential safety hazards.

[0122] Please see Figure 7 In some embodiments, step 03 includes:

[0123] 031: Receive pairing request from the charging dock and send device identity information to the charging dock;

[0124] 032: After successful pairing, the control charging management module connects to the charging dock and sends a charging command to the charging dock, which then charges the battery.

[0125] In some embodiments, the charging command is the same as the first signal. Thus, the pairing mechanism enables authentication and charging command interaction between the charging dock 20 and the electronic stringless guitar 10, achieving intelligent control of the charging process, avoiding the risk of unauthorized device misconnection, and improving charging safety. Simultaneously, automated pairing and command transmission simplify user operation steps, allowing users to complete the charging connection without manual setup, thus optimizing the user experience.

[0126] In this embodiment of the application, the pairing type is Bluetooth pairing, that is, the Bluetooth host 18 of the electronic stringless guitar 10 and the Bluetooth slave of the charging dock 20 are used to achieve pairing connection. The device identity information includes device serial number (SN), Bluetooth MAC address, device model, user account ID, device name, etc., which can be selected according to actual needs.

[0127] Please see Figure 7 In some embodiments, step 03 further includes:

[0128] 033: Monitor the charging voltage of the charging dock;

[0129] 034: When the charging voltage is within the preset range, the battery is charged using the power provided by the charging dock.

[0130] In this way, the electronic stringless guitar 10 is charged when the charging voltage of the charging base 20 is within the preset range, which can not only prevent damage to the electronic stringless guitar 10 and extend the life of the battery 11, but also ensure the activation of the fast charging protocol and reduce energy consumption.

[0131] Specifically, in some embodiments, sub-steps 031 and 032 can be implemented by the charging management module 14, or the charging management module 14 can be used to monitor the charging voltage of the charging base 20; when the charging voltage is within a preset range, the electronic stringless guitar 10 is controlled to charge through the charging base 20.

[0132] In this embodiment, when the charging dock 20 charges the electronic stringless guitar 10, if the charging voltage of the charging dock 20 is higher than the rated value of the battery 11 or the charging circuit, it may cause the battery 11 to overheat or the circuit to be damaged, thereby accelerating the aging of the battery 11, or even burning out the charging management chip, causing the device to fail to power on or short-circuit. If the charging voltage of the charging dock 20 is too low, charging may not be able to start, or the charging efficiency may be extremely low, causing the device to repeatedly attempt to charge and consume extra power. Therefore, before charging the electronic stringless guitar 10 with the charging dock 20, it is necessary to ensure that its charging voltage is within a preset range.

[0133] Furthermore, in this embodiment, the preset range is 4.5V to 25V. The charging management module 14 (such as a buck-boost architecture) needs to function normally when the input voltage is higher or lower than the battery voltage 11. For example, when using a 5V adapter to charge a 9V battery 11, the charging management module 14 needs to boost the voltage; while when using a 24V power supply to charge a 12V battery 11, the charging management module 14 needs to buck the voltage. Therefore, setting the preset range to 4.5V to 25V provides sufficient voltage adjustment space for the charging management module 14.

[0134] In some embodiments, the electronic stringless guitar further includes a battery management system, and the charging method further includes:

[0135] Step 07: Obtain battery parameters;

[0136] Step 08: Obtain the charging electrical information sent by the charging dock, generate a charging termination signal based on the charging electrical information and battery parameters, and send the charging termination signal to the charging dock to terminate charging.

[0137] In this way, by monitoring battery parameters (such as voltage and current) in real time through the battery management system and combining the charging electrical information (such as output power and charging status) fed back by the charging dock 20, dynamic and precise control of the charging process is achieved. When the battery is detected to be fully charged or an abnormal charging condition is detected, a termination signal can be generated in a timely manner and sent to the charging dock, effectively preventing risks such as overcharging and overcurrent, and extending battery life. At the same time, this mechanism allows the charging process to adapt to the power supply capabilities of different charging docks (such as fast charging or normal charging), improving charging compatibility and efficiency.

[0138] In some embodiments, the controller 15 can determine whether the battery 11 is fully charged or whether an abnormality has occurred based on the charging electrical information and battery parameters, and then send a charging termination signal to control the charging dock to terminate charging. For example, the controller 15 can detect the charge level of the battery 11 and send a charging termination signal when the charge level of the battery 11 is 100% to control the charging dock 20 to terminate charging.

[0139] In some embodiments, the controller 15 can also determine whether the battery 11 is fully charged based on battery parameters such as battery voltage, charging current, and charging protocol status.

[0140] In some embodiments, the controller 15 may also determine whether an abnormality has occurred during charging based on charging electrical information such as battery temperature, output voltage stability, and output current limit, and then send a charging termination signal to control the charging dock to terminate charging.

[0141] In some embodiments, the charging termination signal is used to control the charging management module 14 to disconnect the power supply and stop charging the battery 11.

[0142] Please see Figure 2 and Figure 6 Furthermore, the charging method for the charging dock 20 also includes:

[0143] Step 107: Determine whether a charging termination signal has been received;

[0144] Step 108: When a charging termination signal is received, disconnect the charging dock output terminal.

[0145] Specifically, after receiving a charging termination signal, the main controller 21 of the charging dock can control the output terminal 25 of the charging dock to disconnect through the output control module 24, thereby stopping the charging dock 20 from charging the electronic stringless guitar 10.

[0146] Please see Figure 1 and Figure 8 In some embodiments, the electronic stringless guitar 10 also includes a battery management system 17, and the charging method further includes:

[0147] Step 07: Control the battery management system to monitor battery parameters and issue an error message when parameters are abnormal.

[0148] Thus, after charging is complete, the battery management system 17 enters maintenance mode to monitor the status of the battery 11, which helps to ensure the health of the battery 11.

[0149] Specifically, in some embodiments, steps 05 and 06 can be implemented by the charging management module 14, or the charging management module 14 can be used to control the battery management system 17 to monitor the parameters of the battery 11 and issue an abnormal prompt when the parameters are abnormal.

[0150] In this embodiment, after the electronic stringless guitar 10 is fully charged, the system enters maintenance mode. The battery management system 17 monitors the status of the battery 11 to ensure the health of the battery 11, and issues a fourth signal to remind the user when abnormal parameters occur, thereby ensuring the health and safety of the battery 11 of the electronic stringless guitar 10.

[0151] Please see Figure 2 and Figure 6 Furthermore, in some embodiments, after the electronic stringless guitar 10 has been charged using the charging base 20, the status of the battery 11 can also be monitored through the charging base 20.

[0152] In some embodiments, when the electronic stringless guitar 10 is charged via the charging dock 20, the charging dock 20 is also used to receive the first signal, and the charging method of the charging dock 20 includes:

[0153] Step 109: When the first signal is not received or the charging termination signal is received, the control parameter detection module monitors the battery parameters and issues an abnormal prompt when the parameters are abnormal.

[0154] Specifically, when the charging dock main controller 21 does not receive the first signal or after receiving the third signal, it can monitor the parameters of the battery 11 through the parameter detection module 23 to ensure the health of the battery 11, and issue an abnormal prompt to remind the user when abnormal parameters occur, thereby ensuring the health and safety of the battery 11 of the electronic stringless guitar 10.
