Embodiment 1
[0063] see figure 1 , which is a schematic diagram of Embodiment 1 of the supercapacitor audio device provided by the present invention.
[0064] The supercapacitor audio device provided in this embodiment includes: a supercapacitor module 100, a charge management module 200, a DC voltage regulator module 300, a power amplifier module 400, an audio decoding module 500, and a speaker 600;
[0065] The charging management module 200 is configured to control the supercapacitor module 100 to stop supplying power to the DC voltage stabilizing module 300 when an external DC power supply is detected, and at the same time control the external DC power supply to the supercapacitor module 100 charging; it is also used to control the supercapacitor module 100 to supply power to the DC voltage stabilizing module 300 when it is detected that no external DC power supply is connected;
[0066] It should be noted that the voltage level of the external DC power supply can be selected accordin...
Embodiment 2
[0081] see figure 2 , which is a schematic diagram of Embodiment 2 of the super capacitor audio device provided by the present invention.
[0082] The supercapacitor audio device provided in this embodiment further includes: a first voltage detection module 700 and a first charge-discharge equalization control module 800;
[0083] The first voltage detection module 700 is configured to detect the voltage at both ends of each supercapacitor, and send the detected voltage to the first charge-discharge balance control module 800;
[0084] The first charge-discharge balance control module 800 is configured to stop charging the supercapacitor when the voltage across the supercapacitor exceeds a first reference voltage value; the first reference voltage value is obtained by sampling the supercapacitor in advance .
[0085] It should be noted that the first reference voltage value is obtained by performing voltage sampling on the supercapacitor.
[0086] To sample the reference v...
Embodiment 3
[0090] see image 3 , which is a schematic diagram of Embodiment 3 of the supercapacitor audio device provided by the present invention.
[0091] The supercapacitor audio device provided in this embodiment further includes: a second voltage detection module and a second charge-discharge equalization control module;
[0092] The second voltage detection module is used to detect the sum of the voltages of all supercapacitors in the supercapacitor module, and send the detected voltage sum to the second charge-discharge equalization control module;
[0093] The second charge-discharge balance control module is configured to cut off the charging path between the charge management module and the supercapacitor module when judging that the sum of the voltages exceeds a first predetermined voltage value Vref1.
[0094] The following example introduces a specific implementation method, such as image 3 shown.
[0095] The second charge-discharge balance control module includes: a fi...
