Abstract
The electrostatic transducer 100 comprises an electrically conductive first member 102 having an array of through apertures or perforations 112 and one or more further members 104, 106. The one or more further members 104, 106 include a flexible electrically conductive second member 106 arranged in use to be displaced from an equilibrium position towards the first member 102 by an electrostatic force in response to an electrical potential applied to one or both of the first member 102 and the second member 106. At least one 104 of the one or more further members is resiliently deformable and is arranged in use to exert a resilient biasing force biasing said second member 106 back towards said equilibrium position when displaced therefrom by said electrical potential. The resilience of member 104 may be brought about by its non-planar shape, e.g. the protrusions 114.
