Abstract:
1. A computing device, comprising: a case; an audio signal processing unit configured for compressing or decompressing a digital audio data into an audio signal; an amplifier circuit connected to the audio signal processing unit and is configured for amplifying an amplitude of the audio signal; a single shot trigger circuit connected to the amplifier circuit and configured for generating a pulse width modulation (PWM) signal according to the amplified audio signal; a single chip processor connected to the single shot trigger circuit and configured for generating a driving signal according to the PWM signal; and a driver circuit connected to the single chip processor and configured for generating driving voltages; and a light module mounted on an outside surface of the case and connected to the driver circuit, the driver circuit being configured for driving the light module to light using the driving voltages such that a brightness of the light module varies with the amplitude of the audio signal in real-time.
