The present invention is an audio controlled LED decoration lamp string system that mainly is to design a system with flashing function by inputting the audio source's frequency to directly control the LED decoration lamp string and create the variation of light and shade. The said system can be electrically-conducted in from a first sector capable of providing the AC (alternate current) or DC (direct current) power to a second sector's IC and electrically-conducted in a fifth sector's LED lamp string simultaneously. And, the second sector's IC is separately electrically-conducted with a third sector's MIC (audio source receiver) and a fourth sector's PWM (pulse width modulation). The fourth sector's PWM is then electrically conducted with a fifth sector's LED lamp string to form a complete system.
An audio controlled LED decoration lamp string system including five operating sectors that is electrically-conducted in from a first sector capable of providing the AC (alternate current) or DC (direct current) power to a second sector's IC and electrically-conducted in a fifth sector's LED lamp string simultaneously, and the second sector's IC is separately electrically-conducted with a third sector's MIC (audio source receiver) and a fourth sector's PWM (pulse width modulation), then is electrically conducted in and controls a fifth sector's LED lamp string through the fourth sector's PWM to form a complete system.
