LIGHT EMITTING SPEAKER, LIGHT EMITTING SPEAKER SYSTEM, AND DRIVING METHOD THEREOF

摘要

The present invention provides a light emitting speaker, a light emitting speaker system, and a driving method thereof which can harmoniously display light of various colors according to a sound. According to an aspect of the present invention, the light emitting speaker comprises a light emitting element and a speaker to generate a sound and light corresponding to an inputted sound source, and further comprises: a spectrum converter to determine a visible frequency corresponding to a frequency of the inputted sound source; a light emitting element drive circuit to control the light emitting element to emit light corresponding to the inputted sound source according to an output of the spectrum converter; and the light emitting element driven by a control signal of the light emitting element drive circuit. The spectrum converter generates a nonlinear variable, and nonlinearly divides a frequency range of the sound source according to the nonlinear variable to generate a plurality of groups and assign a color to each group.;COPYRIGHT KIPO 2016
