Wireless Audio Gateway Headset
First Claim
1. A wireless, multiple audio gateway headset for providing communication between the headset and at least one audio gateway, the headset comprising:
- a housing, the housing having at least one multifunction button, a first and a second microphone, wherein the first microphone is located closer to a user'"'"'s mouth than the second microphone, a flexible ear bud, a speaker, a volume control button, a rechargeable battery, and a USB port;
a detachable ear wrap; and
a programmable baseband IC, wherein the programmable baseband IC is configured for wireless communications for interfacing between the at least one audio gateway and the wireless headset, and wherein an audio sample is processed in approximately 2 milliseconds.

Abstract
A wireless, multi-function audio gateway device provides communication between the headset and at least one audio gateway. The headset includes a housing having at least one multifunction button, and a first and a second microphone. The first microphone is located closer to a user'"'"'s mouth than the second microphone. The headset also includes a flexible ear bud, a speaker, a volume control button, a rechargeable battery, a USB port, a detachable ear wrap, and a programmable baseband IC. The programmable baseband IC is configured for wireless communications to allow interfacing between the at least one audio gateway and the wireless headset. Methods for improved noise suppression, pairing and communicating with multiple audio gateways simultaneously, and allowing headset-to-headset communications between two wireless, multiple audio gateway headsets are also disclosed.

7. A method for suppressing background noise for a wireless, multiple audio gateway device, the method comprising the steps of:
-
collecting first analog audio signals from a first microphone; collecting second analog audio signals from a second microphone; filtering the first analog audio signals from the first microphone through a first bandpass filter to remove non-speech audio; filtering the second analog audio signals from the second microphone through a second bandpass filter to remove non-speech audio; converting the first and second analog audio signals to first and second digital signals; aligning the first and second digital signals; exploiting the time difference between the digital audio signals from the first microphone and the digital audio signals from the second microphone to remove background noise and undesired speakers; eliminating an undesired frequency spectrum; and adding the first and the second digital signals to create a final enhanced output. - View Dependent Claims (8, 9, 10)

11. A method for communicating with multiple audio gateways simultaneously for a wireless, multiple audio gateway device, the method comprising the steps of:
-
registering a first hands free service on a first channel on the device; pairing a first audio gateway with the device on the first channel; unregistering the first service on the first channel; registering a second service on a second channel; pairing a second audio gateway with the device on the second channel; and activating the first channel; and activating the second channel. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
