  • Patent number: 9117437
    Abstract: A noise cancelling headphone is described. The noise cancelling headphone utilizes a low power consuming noise cancellation circuit wherein an audio input signal is directly fed into the headphone without the use of an additional headphone amplifier. The noise cancelling circuit uses a microphone to pick up ambient noise and produces a signal which is equal in amplitude but opposite in polarity to the ambient noise signal. The resultant signal is mixed with the audio input signal and fed into the speakers of the headphone. This method is advantageous because it uses fewer components than conventional noise cancellation circuits and it also consumes less power due to the use of fewer components. The distortion of the audio input signal is also reduced since no amplification is performed to the audio input signal onboard the noise cancellation circuit.
