  • Active Noise Cancellation Device
    Publication number: 20190122650
    Abstract: An active noise cancellation device includes a first input for receiving a microphone signal from the microphone, a first electrical compensation path and a second electrical compensation path being coupled in parallel between a first node and the first input to provide a first noise canceling signal for a feed-backward prediction of a noise source, a third electrical compensation path and a fourth electrical compensation path being coupled in parallel between a second node and the first input to provide a second noise canceling signal for a feed-forward prediction of the noise source.

  • Active noise cancellation device
    Patent number: 10147411
    Abstract: An active noise cancellation device for cancelling a primary acoustic path between a noise source and a microphone by an overlying secondary acoustic path between a canceling loudspeaker and the microphone, the device comprising: a first input for receiving a microphone signal from the microphone; wherein the first electrical compensation path and the second electrical compensation path are coupled in parallel between a first node and the first input to provide the first noise canceling signal for a feed-backward prediction of the noise source; wherein the third electrical compensation path and the fourth electrical compensation path are coupled in parallel between a second node and the first input to provide the second noise canceling signal for a feed-forward prediction of noise source.
