System and method of improving voice quality in a wireless headset with untethered earbuds of a mobile device
First Claim
1. A method of improving voice quality of a mobile device using a wireless headset with untethered earbuds comprising:
- receiving a first group of acoustic signals from a first front microphone, a first rear microphone and a first end microphone, respectively, included in a first untethered earbud;
receiving a second group of acoustic signals from a second front microphone, a second rear microphone, and a second end microphone, respectively, included in a second untethered earbud;
determining whether the first earbud is in-ear or whether it is out-ear based on a power ratio of a pair of the first group of acoustic signals,determining whether the second earbud is in-ear or whether it is out-ear based on a power ratio of a pair of the second group of acoustic signals;
receiving a first inertial sensor output from a first inertial sensor included in the first earbud and receiving a second inertial sensor output from a second inertial sensor included in the second earbud;
transmitting by the first earbud the first group of acoustic signals and the first inertial sensor output when the first earbud is determined to be in-ear, and not when the first earbud is determined to be out-ear; and
transmitting by the second earbud the second group of acoustic signals and the second inertial sensor output when the second earbud is determined to be in-ear, and not when the second earbud is determined to be out-ear.

Abstract
Method of improving voice quality using a wireless headset with untethered earbuds starts by receiving first acoustic signal from first microphone included in first untethered earbud and receiving second acoustic signal from second microphone included in second untethered earbud. First inertial sensor output is received from first inertial sensor included in first earbud and second inertial sensor output is received from second inertial sensor included in second earbud. First earbud processes first noise/wind level captured by first microphone, first acoustic signal and first inertial sensor output and second earbud processes second noise/wind level captured by second microphone, second acoustic signal, and second inertial sensor output. First and second noise/wind levels and first and second inertial sensor outputs are communicated between the earbuds. First earbud transmits first acoustic signal and first inertial sensor output when first noise and wind level is lower than second noise/wind level. Other embodiments are described.
