Abstract
A transducer includes a first and second spaced apart member, each member having a radiating surface for producing a wave of energy in a transmitting medium in response to a driving force, a plurality of containment devices coupled to each member and extending outwardly beyond at least one radiating surface for communicating the driving force to each member, and a corresponding plurality of driving devices respectively disposed within the containment devices for generating the driving force in response to a change in a predetermined dimension of the driving device. The distance between the members and corresponding distance between the radiating surfaces may be reduced for increasing the bandwidth of the transducer, while the length of the containment device may be increased for accommodating the driving devices in order to maintain a constant driving force. A method for selecting the bandwidth of operation of a transducer is also described.
