Abstract
An electromechanical force transducer having an intended operative frequency range comprises a resonant element () having a periphery and having a frequency distribution of modes in the operative frequency range, characterized by support means () coupled to the periphery of the resonant element, the support means () having a substantially restraining nature in relation to bending wave vibration of the resonant element (). The transducers may be mounted to an acoustic radiator () in a loudspeaker via coupling means () to excite the acoustic radiator to produce an acoustic output.
