Abstract

The present invention relates to an auto conversion system of multiple light-emitting diodes for audio equipment, which can colorize sound by granting a pitch code to the sound and converting a signal to automatically control and change an LED color according to the pitch code. For this end, the auto conversion system of the present invention comprises: a voice detector (10) for classifying and detecting sound transmitted from various kinds of audio equipment such as an audio system, TV, and display device; a pitch code converter (20) for coding a voice detected by the voice detector (10) to a pitch (Hz); a digital converter (30) for converting the pitch of the pitch code converter (20) to a digital signal; a pulse converter (40) for converting the digital signal of the digital converter (30) to a pulse modulation module; a signal converter (50) for converting the pulse modulation module of the pulse converter (40) to a power signal; a constant current converter (60) for converting the power signal of the signal converter (50) to a constant current; and a constant current controller (70) for controlling the constant current of the constant current converter (60) and converting the current to a variable signal to vary the color of an LED (80).
