Abstract
A computer microphone with a dual power source capability is disclosed. This dual power source capability allows the microphone to receive power from an internal power source or an external power source disposed in computer hardware. In the event that the computer microphone is receiving power from the internal power source, and power is thereafter provided from the external source disposed in computer hardware, the present invention provides for the automatic turning off of the internal power source. In related fashion, in the event the computer microphone is receiving power from the external power source disposed in the computer hardware, and that external power source is thereafter turned off, the present invention automatically provides the computer microphone with power from the internal power source.
