  • Magnetically controllable transducer backing component
    Patent number: 9602915
    Abstract: A transducer is provided that converts energy between two forms using active components. The transducer also includes passive components in contact with the active components that perform passive component functions separate from the energy conversion function. The passive components include ferrofluids and have elastic properties that are modifiable by exposure of the passive component to a magnetic field to selectively control the energy conversion function.
