  • Patent number: 8213643
    Abstract: A sound transducer for the transmission of audio frequency signals with a pressure-voltage transducer is provided. This pressure-voltage transducer is disposed on a supporting plate and at least partially embedded in a sound-insulating, substantially incompressible material, for example a gel. The supporting plate rests herein in contact on a body part, for example a jaw or skull bone, of a person. If this person conducts a conversation, the vibrations of the bone generated through the conversation are transmitted to a supporting plate. This supporting plate subsequently transmits the vibrations onto the pressure-voltage transducer, for example a piezoelectric element or an electret element.
    Type: Grant
