Abstract
[Feature] Recent research in transducer technology involves monitoring and controlling the displacement of loudspeaker drivers to ensure that they can be driven as hard as possible with the best sound quality. The requirements for designs to be used with so-called smart amplifiers are also outlined. Alternatives to the conventional moving-coil driver are still being explored and some of the criteria for new transducers are introduced. Graphene appears to be an interesting and useful material that may find a role in the microphones of the future, while moving magnet subwoofers seem to have a number of desirable properties that could enable high outputs with minimal power compression and low distortion.
