Abstract
The utility model provides a sound box companion, which is formed by that according to the magnitude of an audio signal, a line input audio signal, a power input audio signal, or a microphone input audio signal is divided into four kinds of a high audio, a medium audio, a low audio, and no audio. By each colour lamp controller of the audio signals, the variation of various colour lamps matched with the variation of a high, a medium, and a low frequencies of music is realized. A synchronous or a time delay effect can also cause the colour lamps to generate various harmonious colours other than a natural color. The utility model not only can be matched with a present sound box, but also can be made into integration with a sound box.
Description
The utility model relates to a kind of audio amplifier, specifically a kind of Colour changeable lamp device mated with loadspeaker that audio amplifier and light are integrally combined.
