Resonant element transducer

摘要

A transducer ( 14 ) for producing a force which excites an acoustic radiator, e.g. a panel ( 12 ) to produce an acoustic output. The transducer ( 14 ) has an intended operative frequency range and comprises a resonant element which has a distribution of modes and which is modal in the operative frequency range. Parameters of the transducer ( 14 ) may be adjusted to improve the modality of the resonant element. A loudspeaker ( 10 ) or a microphone may incorporate the transducer.
