Abstract
A noise cancelling headset includes an earpiece, the earpiece including a feedback microphone, a feed-forward microphone, and an output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.
Claims20
Noise cancelling earbuds comprising:
- a feed-forward microphone;
- a feedback microphone;
- an output driver configured to receive an antinoise signal based on a combination of input from the feed-forward microphone and the feedback microphone;
- and
- an acoustic structure housing the output driver;
- wherein a voice signal of a user of the noise cancelling earbuds is generated using input from the feed-forward microphone and the feedback microphone.
A method of generating a voice signal of a user of noise cancelling earbuds, the noise cancelling earbuds including a feed-forward microphone, a feedback microphone, and an acoustic structure housing an output driver, the method comprising:
- receiving, at the output driver, an antinoise signal based on a combination of input from the feed-forward microphone and the feedback microphone;
- and
- generating a voice signal of the user of the noise cancelling earbuds using input from the feed-forward microphone and the feedback microphone.
