US 11,706,856 B2 · Band-pass filtering adaptive response method and system for music lamp strip

Abstract

The present invention provides a band-pass filtering adaptive response method and system for music lamp strip. The method comprises the following steps: Step 1: obtaining sound data acquired by a microphone in real time, and sequentially filtering the obtained sound data through a low-pass filter; Step 2: classifying the filtered sound data by a volume classifier, so as to classify the continuous changes of sound into a number of discrete classifications; Step 3: determining a BPM of the sound data according to a classification result of the volume classifier; Step 4: determining a acquisition frequency of MCU according to the determined BPM; Step 5: acquiring the classification result of the volume classifier by MCU according to the determined acquisition frequency; Step 6: controlling color change and/or brightness change of LED lamp on the music lamp strip according to the classification result acquired by MCU.
