Abstract :
A lumped parameter formulation for the electromechanics of a class of electret transducers is developed. An energy method is used to calculate the force of electrical origin and the technique is employed in the solution of two important electret transducer geometries. The results are checked by a surface integration of the Maxwell stress tensor.
