[0023] The following embodiments and features in the embodiments can be combined with each other under the condition of no conflict.

[0024] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the drawings, rather than being drawn according to the number, shape and size of the components in actual implementation. The shapes, number and proportions of the components in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0025] The integrated charging sound processor of the present application integrates multiple charging modes such as wireless charging, wired charging and solar charging, so that the charging of the sound processor is more flexible and suitable for different application scenarios, thereby being very practical.

[0026] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the embodiments of the present application.

[0027] As shown in Figure 1 In an embodiment, the integrated charging sound processor of the present application includes a solar cell panel 1, a power adapter 2, a wireless charging device 3, a voltage boosting and reducing module 4, a wireless induction module 5, a power management module 6 and a charging power supply 7.

[0028] The solar cell panel 1 is used to convert solar energy into electric energy to provide a first wired charging power supply. The output voltage of the solar cell panel 1 is 3-5V, and the output current is 150mA. Since the voltage output by the solar cell panel 1 will fluctuate, in order to stabilize the output voltage and facilitate compatibility with the commonly used chip voltage on the market, a low voltage of 3-5V is selected. The battery specification of the sound processor is 100mA, and considering the conversion efficiency and using 1C maximum current to charge the battery core, the current specification of the selected solar cell panel is 150mA.

[0029] The power adapter 2 is used to convert an external power supply into a second wired charging power supply. Preferably, the power adapter 2 adopts a 5V power adapter, i.e. a power adapter with an output voltage of 5V.

[0030] The wireless charging device 3 is used to provide a wireless charging power supply. The wireless charging device 3 meets the Qi protocol. The Qi protocol is a wireless charging standard proposed by the Wireless Power Consortium (WPC), which has the characteristics of convenience and universality.

[0031] The boost and buck module 4 is connected to the solar panel 1 and the power adapter 2, and is used to convert the first wired charging power supply and the second wired charging power supply into a stabilized voltage power supply. Specifically, the input voltage of the boost and buck module 4 is 1V-6V, and the output voltage is 5V. Since the voltage output by the solar panel 1 may fluctuate, in order to better adapt to the output power of the solar panel, the selected input voltage range is 1V-6V. The fixed output voltage is to ensure the stability of the charging. Therefore, the first wired charging power supply and the second wired charging power supply are converted into a stabilized voltage power supply with a fixed voltage after passing through the boost and buck module 4. In an embodiment, the boost and buck module 4 is connected to the solar panel 1 and the power adapter 2 based on a switching terminal. The switching terminal can adopt a TYPE-C interface or a magnetic attraction interface. Preferably, the boost and buck module 4 adopts a boost and buck chip TPS63900. As shown in Figure 2 , the output voltage VOUT of the boost and buck chip can be configured by R1, R2, and R3, and the set VOUT is 5V.

[0032] The wireless induction module 5 is coupled to the wireless charging device 3, and is used to convert the wireless charging power supply into an induction power supply. Specifically, the wireless induction module 5 includes an induction coil 51 and a wireless charging chip 52. The induction coil 51 is used to be coupled to the wireless induction module 3 to generate an induction voltage. The wireless charging chip 52 is connected to the induction coil 51, and is used to generate the induction power supply based on the induction voltage. The wireless charging device 5 meets the Qi protocol output power ≥1W, that is, if the output voltage is 5V, the output current can reach 200mA. In an embodiment, the circuit diagram of the wireless induction module 5 is as shown in Figure 3 , which adopts a chip STWLC38, meets the Qi protocol, and the maximum output power is 15W.

[0033] The power management module 6 is connected to the boost and buck module 4 and the wireless induction module 5, and is used to charge the charging battery 7 based on the stabilized voltage power supply and the induction power supply. The power management chip can be used for charging management of a 3.7V-4.2V charging battery. In an embodiment, the power management module 6 adopts a power management chip. The charging battery 7 adopts a charging lithium battery. As shown in Figure 4As shown, the power management module 6 adopts a chip TP4059, wherein VOUT is the output voltage of the step-up / down module, V-BAT is connected to the positive electrode of the charging lithium battery, and GND is connected to the negative electrode of the charging lithium battery. The charging current I = 1000 / R7, which meets the charging requirements of the charging lithium battery.

[0034] Therefore, the solar panel 1, the power adapter 2 and the wireless charging device 3 respectively provide a solar charging power supply, a wired charging power supply and a wireless charging power supply, and after the voltage stabilization processing of the step-up / down module 4, the charging battery 7 is charged in multiple modes through the power management module 6, thereby being applicable to various application scenarios.
