  • Publication number: 20090141906
    Abstract: A communication headset includes first and second domes. The first and second domes include the speaker assembly having a first speaker coil and a second speaker coil. One speaker coil is for receiving a first audio signal, and the second speaker coil is for receiving a second audio signal and an active noise cancellation signal. Each of the speaker coils co-acts with a magnetic field to cause a diaphragm to move responsive to the first and second audio signals and the active noise cancellation signal individually or simultaneously. When the first audio signal is detected, a controller disconnects the second audio signal from the first dome of the headset.
