  • Foam mounted receiver for communication headset
    Patent number: 6731771
    Abstract: A communication headset includes at least one dome structure for fitting over a user's ear, the dome structure comprising a rigid outer housing defining an earpiece cavity. A support structure supports the at least one dome structure in place covering the user's ear. An audio transducer is positioned within the cavity for converting electrical signals into audible signals. A suspension structure supports the transducer within the cavity without any rigid connection between the transducer and the rigid outer housing. Flexible wiring is passed between the transducer and an external connector structure, the wiring for carrying the electrical signals to the transducer.
