Abstract:
An apparatus including a noise acoustical chamber implement and an audio acoustical chamber implement. Said noise acoustical chamber is a generally sealed space to form first-stage passive noise reduction (PNR), wherein first vibratable diaphragms are disposed and first-stage active noise cancellation (ANC) signal processing are further implemented to reduce noise. Said audio acoustical chamber is another generally sealed space around eardrum and is enclosed by said noise acoustical chamber. Said audio acoustical chamber forms second-stage PNR, wherein second vibratable diaphragms are disposed to only generate sound wave of audio signal or at the same time utilize second-stage ANC signal processing to further reduce noise in said audio acoustical chamber.

Claim (Index 1):
An apparatus comprising:\n a noise acoustical chamber implement, said noise acoustical chamber comprises a first chamber that is configured to form a first generally sealed space; a headphone external structure, said headphone external structure is configured to enclose said first chamber; first chamber microphones, said first chamber microphones are configured to pick up and converter environment sound or noise in said noise acoustical chamber into noise signal; a first processor, said first processor comprises an input that is configured to receive said noise signal, wherein said first processor is configured to implement first-stage active noise cancellation (ANC) signal processing to said noise signal and generate first anti-noise signal to be the input of said noise driver; a noise driver mechanism, said noise driver is configured to receive said first anti-noise signal of said first processor, wherein said noise driver comprises one or more vibratable audio diaphragms operable for generating a first anti-noise sound wave based on said output of said first processor; and in which said headphone external structure comprises an external_isolator configured as a first-stage passive noise reduction (PNR) operable for downgrading said environment sound to at least one of, a downgraded, a weakened and a residual noise in said noise acoustical chamber.
