Abstract:
An electromechanical force transducer having an intended operative frequency range comprises a resonant element (10) having a periphery and having a frequency distribution of modes in the operative frequency range, characterised by support means (16) coupled to the periphery of the resonant element, the support means (16) having a substantially restraining nature in relation to bending wave vibration of the resonant element (10). The transducers may be mounted to an acoustic radiator (12) in a loudspeaker via coupling means (14) to excite the acoustic radiator to produce an acoustic output.
