FIG. 1 illustrates a schematic block diagram of the audio controlled power supplying system according to the first embodiment of the present invention. Referring to FIG. 1, an audio controlled power supplying system 1 may have an audio input unit 10, a processor 12 and a power regulator 13. The audio input unit 10 receives an audio signal inputted from an audio source. The processor 12 is electrically coupled to the audio input unit 10, and the processor 12 receives the audio signal and analyzing the audio signal to generate a control signal. The power regulator 13 is electrically coupled to the processor 12, and the power regulator 13 receives the control signal from the processor 12 and regulates an input power signal of a power source, such as AC power or the like, according to the control signal to generate an output power signal. In addition, the power regulator is selected from the group consisting of an RC circuit, a capacitor circuit, a transistor switch circuit and a diode switch circuit. Furthermore, the processor is selected from the group consisting of central processing unit, microprocessor, application-specific instruction-set processing unit, physics processing unit, digital signal processor, coprocessor and audio processor.

Besides, as depicted in FIG. 1, the audio controlled power supplying system 1 may further comprise an illuminating unit 2, which is electrically coupled to the power regulator 13. The illuminating unit 2 can be driven to illuminate light with variable brightness according to the output power signal from the power regulator 13. In addition, the illuminating unit 2 may be a built-in illuminating unit in the audio controlled power supplying system 1. Also, the illuminating unit 2 may be an external unit connected to the power output unit 18(as shown in FIG. 5) of the audio controlled power supplying system 1. Furthermore, the illuminating unit 2 may comprise light emitting diode, incandescent light bulb, fluorescent lamp, sodium vapor lamp, high intensity discharge lamp or the like.

Besides, as drawn in FIG. 1, the audio controlled power supplying system 1 may further comprise an audio output unit 11, which is electrically coupled to the audio input unit 10. The audio output unit 11 may output the audio signal received from the audio input unit 10. It is worthy to note that the audio output unit 11 may be arranged as a built-in audio output device in the audio controlled power supplying system 1, or may be arranged as an external device, such as a speaker 3, which is shown in FIG. 3. Both of them may output the audio signal in a form of acoustic sound wave, analog audio signal, digital audio signal or the like.

While the audio controlled power supplying system 1 is under operation, the inputted audio signal can be analyzed by the processor via the amplitude analysis, frequency analysis or spectrum analysis. For one example, the whole audio signal is sampled at a predetermined sampling rate, and thereby the amplitude of the audio signal at each sampling point of time may be determined. Such sampled signal of amplitude analysis may be served as the control signal. For another example, signals of one or more frequency of the audio signal may be extracted after spectrum analysis. The extracted signals may then be superimposed or mixed together to serve as the control signal. After that, the power regulator 13 may regulate the input power signal according to the control unit and then output the output power signal to the illuminating unit 2, so as to drive the illuminating unit 2 illuminating light according to the output power signal to perform dim, different brightness level or flash effect. As the result, with different kinds of the music or audio signals including different tempo, different amplitude of sound or the like, the illuminating unit 2 will illuminate the light accordingly,

As the result, when the control signal is transmitted to the power regulator 13 during the switch status of the regulator switch 14 being on, the power regulator 13 will output the output power signal to illuminate the illuminating unit 2 according to the control signal. When the control signal is not transmitted to the power regulator 13, the illuminating unit 2 will simply be illuminated by the power regulator 13, without manipulating the output power signal. Hence, the regulator switch 14 can provide a simplest method for the users to turn ON/OFF the light show of the illuminating unit 2 according to any kind of the music in any time or any where if they desire to do so.
