[0048] Furthermore, the delay adjustment module 4 includes a first diode D1, a sixth switch V6, a seventh switch V7, a ninth resistor R9, a second diode D2, and a first counter IC3;

[0049] Specifically, the anode of the first diode D1 is connected to the base of the sixth switch V6 and the ninth terminal of the first voice controller IC1.

[0050] In a specific embodiment, both the sixth switch V6 and the seventh switch V7 can be NPN transistors; the first counter IC3 can be a CD4017 chip.

[0051] In this embodiment of a multi-functional delay LED circuit, DC power is supplied through a power interface. The first capacitor C1 performs filtering. Initially, in the absence of light, the resistance of the first photoresistor RG1 increases, the seventh capacitor C7 stores energy and triggers the fifth switch V5 to conduct, energizing the first timer IC2 and putting it into operation. The ninth terminal of the first sound controller IC1 outputs a low level. When the first microphone B1 detects sound, the bistable multivibrator within the first sound controller IC1 flips, causing the ninth terminal of the first sound controller IC1 to output a high level, thereby controlling the first switch V1 to conduct and controlling the sixth... When switching transistors V6 and V7 are turned on, the DC power supplied to the power interface is transmitted to the first counter IC3 through the seventh switch V7, triggering the third terminal of the first counter IC3 to output a high level. At this time, the second switch V2 is turned on. The fourth resistor R4 is connected to the second and sixth terminals of the first timer IC2, and together with the fifth capacitor, the delay time is set. Since the first switch V1 is turned on, the level of the second terminal of the first timer IC2 is pulled low, causing the third terminal of the first timer IC2 to output a high-level signal, which in turn controls the first power transistor Q1 and the seventh switch V7 to turn on during the delay time. The system controls the LED lights to provide delayed illumination and keeps the first counter IC3 operational. If the first microphone B1 detects sound a second time within the delay period, the first sound controller IC1 will output a high level again, triggering the sixth switch V6, the seventh switch V7, and the first switch V1 to conduct. The first counter IC3 will then start counting and output a high level from its second terminal, turning on the third switch V3. The fifth resistor R5 and the fifth capacitor set the delay time. Since the resistance of the fifth resistor R5 is greater than that of the fourth resistor R4, the delay time is increased, thus enabling... The high-level signal output from the third terminal of the first timer IC2 is extended. Similarly, after the third, fourth, or fifth sound detection, the fourth switch V4 will be turned on. At this time, the sixth resistor R6 and the fifth capacitor set the delay time, and the delay time is longer than the delay time set by the fifth resistor R5 and the fifth capacitor. After the delay ends, the first timer IC2 outputs a low level. When there is light, the fifth switch V5 is turned off, the first timer IC2 stops working, which causes the first power transistor Q1 to be turned off, the LED to turn off, the seventh switch V7 to be turned off, and the first counter IC3 to be reset.
