An electrostatic transducer (100) comprises an electrically conductive first member (102) having an array of through apertures (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.
