Noise cancellation headset for use with stand or worn on ear

The headset comprising:

• arcuate housing placement over an ear, left or right, of a wearer, said housing having at least one receiver means for transmitting audio signals to the ear;
• arcuate earband structure for placement behind the ear;
• spring means for attaching the earband structure to the housing;
• boom microphone device having two ends, one end having a first and second microphone means for receiving an acoustic sound and for converting said acoustic sound to a microphone signal and the other end having a first pivotal means for connecting the device to the housing;
• electronic connecting means for transmitting audio signals from the receiver means to the ear and for supplying the microphone signal from the boom microphone device to an external communication system by adapter means;
• wherein the arcuate earband structure has two ends, the first end of the earband structure connected to the spring means and the second end of the earband structure opposite the first end connects the earband structure to an earband member by a ball and socket joint;
• and
• wherein the first microphone means receives a first acoustic sound composed of speech originating from the wearer and background noise, and for converting said first acoustic sound to a first microphone signal, the second microphone means arranged at a predetermined angle with respect to said first microphone means for receiving a second acoustic sound composed of substantially said background noise and for converting said second acoustic sound to a second microphone signal, and means for subtracting the second microphone signal from said first microphone signal so as to obtain a signal representing substantially the speech, and whereby the headset is a noise cancellation headset.

A headset comprising:

• arcuate earband structure for placement behind the ear having a first end and a second end;
• the first end attached by movable means to an earband member;
• the earband member having a distal end from attachment to the earband structure;
• the distal end having a means for matingly fitting into an upright stand;
• the second end having spring means for rotatably attaching the earband structure to the housing thereby allowing the earband structure to rotate up to 360.degree. around the housing;
• boom microphone device having a first end and a second end;
• the first end having a microphone means for receiving an acoustic sound and for converting said acoustic sound to a microphone signal;
• the second end having means for connecting the boom microphone device to the housing;
• and
• electronic means for transmitting audio signals from the receiver means to the ear and for supplying the microphone signal from the boom microphone device to an external communication system by adapter means.
