[0072] Further, as Figure 1 、as Figure 10 shown, the sound-controlled magic colored light control circuit further includes a colored light power control module.

One end of the colored light power control module is connected to the power output end of the power input module, and the other end is connected to the colored light module to output a suitable voltage to supply power to the colored light module. In this embodiment, as

The input power supply of each LED light is connected to the output end of the colored light power control module. That is, in the colored light module, each colored light is in series, and the input voltages of each colored light are in parallel. This can save the wiring of the colored lights and reduce costs.

The capacitor C2 is connected in parallel with the capacitor C3.

[0074] Further, as Figure 1 shown in the figure, the present application further includes a key detection module and a remote control detection module.

The main control module controls the colored light module, the cold light module, or the warm light module to emit corresponding light signals according to the signal information transmitted by the key detection module and the remote control detection module.

One end of the light emission mode key MODE is connected to the sixth pin of the control chip, and the other end is grounded.

[0077] The MUSIC button for the music mode is used to control whether the colored light module is linked with the MIC detection module. That is, when the main control module detects the signal input by the MUSIC button for the music mode, the main control module controls the colored light module to be linked with the MIC detection module, that is, controls the flashing of the colored light module to flash along with the received audio signal. In this embodiment, the flashing of the colored light includes the light emission frequency, light emission intensity, and light emission color. The specific flashing structure can be preset and is not limited in this application; among them, one end of the MUSIC button for the music mode is connected to the seventh pin of the control chip, and the other end is grounded;

[0078] The LED button for cold and warm light is used to control the power supply of the cold light module and the warm light module, and can realize the on / off of cold and warm light and the switching between cold and warm light. That is, when the main control module detects the signal input by the LED button for cold and warm light, the main control module controls the cold light module to emit light alone, or the warm light module to emit light alone, or the cold and warm light to emit light alternately, or turn off the cold and warm light according to the number of received button presses; among them, one end of the LED button for cold and warm light is connected to the eighth pin of the control chip, and the other end is grounded.

[0080] Further, as Figure 2 、 Figure 7 shown, the cold light module includes a Pmos transistor Q4, a resistor R9, a resistor R10, a resistor R11, an LED D2, an LED D3, and an LED D4; among them, one end of the resistor R9 is connected to the S source electrode of the Pmos transistor Q4 and the VBUS interface terminal of the power input module, and the other end is connected to the G gate electrode of the Pmos transistor Q4 and the tenth pin of the control chip; one end of the resistor R10 is connected to the D drain electrode of the Pmos transistor Q4, and the other end is connected to the LED D2, the LED D3, and the LED D4; the resistor R11 is connected in parallel with the resistor 10; the other ends of the LED D2, the LED D3, and the LED D4 are grounded.

[0081] Further, as Figure 2 、 Figure 8As shown in the figure, the warm light module includes Pmos transistor Q5, resistor R16, resistor R14, resistor R15, LED D5, LED D6, and LED D7. One end of resistor R16 is connected to the S source electrode of Pmos transistor Q5 and the VBUS interface terminal of the power input module, and the other end is connected to the G gate electrode of Pmos transistor Q5 and the ninth pin of the control chip. One end of resistor R14 is connected to the D drain electrode of Pmos transistor Q5, and the other end is connected to LED D5, LED D6, and LED D7. Resistor R15 is connected in parallel with resistor 14. The other ends of LED D5, LED D6, and LED D7 are grounded.

[0082] Further, as Figure 3 shown in the figure, the power input module includes USB1 and capacitor C12. The two ends of capacitor C12 are respectively connected to the VBUS terminal and the GND terminal of USB1. Among them, the VBUS terminal is the output terminal. In this application, the colored light power control module, the cold light module, the warm light module, and the remote control detection module are all connected to the VBUS terminal. Among them, a C LED linkage control module is provided on the power input module to be used for realizing the linkage control of at least two colored light modules. The colored light module is connected to the CC2 and CC1 terminals of USB1. When there are multiple colored light modules, they can all be connected in parallel to USB1, so that a main control module can control multiple colored light modules simultaneously, without the need to set up a separate control circuit for each colored light module, which can increase the number of controlled colored light modules while effectively saving costs, and make the light emitting frequencies of each controlled colored light module the same, which can reduce the chaos of colored light flashing, making the colored light flashing highly synchronous and beautiful.
