Audio light adjustment method, device and system

Abstract

The invention relates to a light control method of a loudspeaker. The light control method comprises the following steps of: acquiring an audio signal after digitalization to obtain a numerical value corresponding to an amplitude value of the audio signal; keeping the number of light sources which are turned on constant if the numerical value of the audio signal and the numerical value of a previous audio signal are in the same signal intensity interval; reducing the number of light sources which are turned on if the signal intensity interval where the numerical value of the audio signal is located is lower than the signal intensity interval where the numerical value of the previous audio signal is located; and enabling the number of light sources which are turned on to be equal to the level of the signal intensity interval where the audio signal is located if the signal intensity interval where the numerical value of the audio signal is located is higher than the signal intensity interval where the numerical value of the previous audio signal is located. The invention also comprises a light control device and system of the loudspeaker. By the light control method, device and system, the light can be changed with the intensity of an audio signal, excessive blinking of the light can be effectively reduced, and thus, a human eye is prevented from discomfortableness.

Description

technical field [0001] The present invention relates to the field of audio, in particular to an audio light adjustment method, device and system. Background technique [0002] At present, audio products have been developed more and more perfect, which can achieve the effect required by stage art by combining with various existing equipment. However, as the audience's requirements for stage art effects are getting higher and higher, the stage art is constantly updated and developed, especially the comprehensive light and shadow effects of the stage are developing in the direction of system intelligence, digitalization and dynamics. [0003] Although people have produced their own speakers with multi-color lights according to actual needs, the continuous switching of this multi-color lights will make the lights flicker excessively, thereby causing discomfort to human eyes. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the pr...
