Abstract:
A headphone device includes a speaker housing, a first feedforward microphone, and a second feedforward microphone. The first feedforward microphone is coupled to the speaker housing at a first location, and the second feedforward microphone is coupled to the speaker housing at a second location. The headphone device also includes an active noise cancelling (ANC) circuit configured to generate an anti-noise signal based on at least one of a first signal from the first feedforward microphone and a second signal from the second feedforward microphone. The headphone device also includes a speaker configured to generate an audio output at least partially based on the anti-noise signal.
