Abstract

The present invention provides a power supply and computer using the same. The power supply includes a housing having a first surface and second surface. An audio input connector is arranged on the first surface for receiving audio signal. An audio output connector is arranged on the second surface. An AC to DC power conversion module is arranged in the housing for converting AC power into DC power. An audio power amplification module is arranged in the housing for amplifying the audio signal and outputting the amplified audio signal via the audio output connector. A DC to DC power conversion module is arranged in the housing and connected to the AC to DC power conversion module for converting the DC power supplied by the AC to DC power conversion module.

Claims

1. A power supply comprising:

a housing having a first surface and a second surface;

at least one audio input connector arranged on the first surface of the housing for electrically connecting to a computer;

at least one audio output connector arranged on the second surface of the housing;

an AC to DC power conversion module arranged in the housing for converting an AC power to provide a DC power;

an audio power amplification module arranged in the housing and electrically connected to the audio input connector and the audio output connector, respectively, for processing audio signal provided by the computer; and

a DC to DC power conversion module arranged in the housing and electrically connected to the AC to DC power conversion module and the audio power amplification module, respectively, for converting the DC power provided by the AC to DC power conversion module, so as to supply power to the audio power amplification module to operate.

2. The power supply as claimed in claim 1, further comprising an AC power input connector arranged on the second surface of the housing for inputting the AC power to the AC to DC power conversion module.

3. The power supply as claimed in claim 1, further comprising a DC power output cord arranged on the first surface of the housing for supplying the DC power to the computer.

4. The power supply as claimed in claim 1, wherein the at least one audio input connector is electrically connected to a motherboard of the computer for receiving audio signal generated by the computer.

5. The power supply as claimed in claim 4, wherein the at least one audio input connector is selectively to be an S/PDIF, a digital audio input, an inter-IC sound, and an audio analog line-in.

6. The power supply as claimed in claim 1, wherein the at least one audio output connector is an analog output for speaker.

7. The power supply as claimed in claim 1, wherein the audio power amplification module is selectively to be an A-class, a B-class, a C-class, an AB-class, a D-class, and a T-class amplifier.

8. The power supply as claimed in claim 1, further comprising:

a control connector arranged on the first surface of the housing for receiving audio control generated by the computer; and

an audio processing module arranged in the housing for processing the audio signal received by the audio input connector based on the audio control received by the control connector, and outputting the audio signal processed to the audio power amplification module for being amplified and outputted via the at least one audio output connector.

9. The power supply as claimed in claim 8, wherein the audio processing module is powered by the DC to DC power conversion module.

10. The power supply as claimed in claim 8, wherein the control connector is connected to a motherboard of the computer for receiving the audio control generated by the motherboard.
