Abstract
Disclosed herein is an audio lighting device, which includes a wireless module, an audio source control circuit, a light source control circuit, a speaker, and a light source board. The wireless module receives a wireless signal and outputs an audio source control signal. The audio source control circuit receives the audio source control signal and outputs a first analog signal. The light source control circuit receives the audio source control signal and outputs a second analog signal. The speaker receives the first analog signal and outputs audio signal. The light source board receives the second analog signal to control the brightness of the outputted light, in which the brightness of the outputted light is proportional to the volume of the outputted audio signal.
