Noise-canceling headphones including multiple vibration members and related methods

A noise-canceling headphone, comprising:

• a headband;
• an audio input;
• and
• earcups supported proximate ends of the headband, at least one of the earcups operatively connected to the audio input and comprising:
• a housing;
• a first vibration member operatively connected to the audio input and supported at least partially within the housing;
• a second vibration member operatively connected to the audio input and supported at least partially within the housing;
• a microphone supported by the housing;
• and
• a feedback, noise-cancelation circuit configured to reduce a user's perception of an undesirable audible response of the second vibration member, the feedback, noise-cancelation circuit operatively connected to the microphone, the feedback, noise-cancelation circuit configured to compare a signal from the microphone to a predetermined sound pressure level profile for the noise-canceling headphone in a range of frequencies between about 20 Hz and about 60 Hz, the feedback, noise-cancelation circuit configured to generate a noise-canceling signal of a same amplitude as a portion of the signal from the microphone corresponding to the undesirable audible response of the second vibration member, the noise-canceling signal having inverted phase relative to the portion of the signal from the microphone, the feedback, noise-cancelation circuit configured to modify an audio signal from the audio input at least in part by combining the audio signal with the noise-canceling signal, a modified audio signal generated by the feedback, noise-cancelation circuit configured to at least partially cancel at least a portion of an audible response of the second vibration member, the feedback, noise cancelation circuit configured to output the modified audio signal to the first vibration member responsive to comparing the signal from the microphone to the predetermined sound pressure level profile.
