Abstract
A communication device such as a cellular or wireless telephone handset has a light display, such as handset cover light or display backlight, synchronized to audio signals from multiple audio sources such as a microphone or AM/FM receiver. The communication device further includes an audio to illumination conversion apparatus for modulating the light display in response to the audio signal. The audio to illumination conversion apparatus has a plurality of audio filter circuits for filtering the audio signal to restrict frequency content of the audio signal to a pass-band. Multiple integration circuits generate an energy content signal indicating an energy level within the pass-band and for the whole spectrum of the audio signal. An illumination modulator generates a modulation pattern for the light display in response to the energy content signals from a predefined light show.
