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 19):
An apparatus comprising:\n means for forming a first generally sealed space; means for enclosing said first generally sealed space and forming first-stage PNR; means for picking up and converting environment sound or noise in said first generally sealed space into noise signal; means for implementing ANC signal processing to said noise signal; means for generating a first anti-noise signal based on said noise signal; means for utilizing one or more vibrating diaphragms to transduce said first anti-noise signal into first anti-noise sound in said first generally sealed space, wherein forms first-stage ANC and said noise is generally reduced to be at least one of, a downgraded, a weakened and a residual noise signal in said first generally sealed space. means for forming a second generally sealed space around people eardrum; means for enclosing said second generally sealed space in said first generally sealed space and forming second-stage PNR; means for utilizing audio cables or wireless communication technology to build up connection to exchange electrical signals and power electric between enclosure of said first generally sealed space and enclosure of said second generally sealed space; means for provide flexibility to individually replace said enclosures of said first generally sealed space or said second generally sealed space; means for accommodating large capacity battery, wireless receiver and transmitter, ANC circuits, power amplifier or EQ circuits in said enclosure of said first generally sealed space to support functions implemented in said enclosure of said second generally sealed space; means for picking up and converting noise in said first generally sealed space or in said second generally sealed space into second noise signal; means for receiving audio signal coming from user's audio player source; means for implementing second-stage ANC signal processing to said second noise signal and said audio signal; means for generating second ANC output signal from second-stage ANC signal processing; means for utilizing separate one or more vibrating diaphragms to transduce said second ANC output signal into audio sound and second anti-noise sound in said second generally sealed space, wherein forms second-stage ANC and said second anti-noise sound generally cancel noise in said second generally sealed space to produce at least one of, a downgraded, a weakened and a residual noise signal in said second generally sealed space; and means for a switch mechanism to switch input of said diaphragms in said second generally sealed space from said second ANC output signal to said audio signal;
