USB based microphone system
First Claim
1. A powered microphone system for use with a personal computer comprising:
- a Universal Serial Bus interface for coupling said powered microphone system to a Universal Serial Bus, wherein said Universal Serial Bus provides audio data as Universal Serial Bus data to said personal computer from said powered microphone system;
an integrator/extractor circuit coupled to said Universal Serial Bus interface configured to extract a plurality of data streams from said Universal Serial Bus data, wherein said data streams include clock data and control data;
a controller coupled to said extractor and configured to provide control signals to a power supply and amplifier; and
an audio data circuit coupled to receive said clock data and audio data, wherein said audio data circuit is further configured to receive an audio control signal from said controller, and wherein said integrator/extractor circuit is configured to integrate said audio data into a plurality of data streams as Universal Serial Bus data.

Abstract
A powered microphone for use with a personal computer comprising a Universal Serial Bus interface for coupling the powered microphone to a Universal Serial Bus. A circuit coupled to the Universal Serial Bus interface is configured to integrate a plurality of data streams, including clock data, digital audio data, and control data into Universal Serial Bus compatible data. A gain controller is coupled to provide control signals to a power supply and amplifier; and an audio data circuit is coupled to receive clock data and analog audio data. The audio data circuit includes an analog-to-digital converter for converting the analog audio data to a digital audio signal, and the audio data circuit is further configured to receive an audio control signal from the gain controller.
