ACCURATE MODEL FOR THE PUSH-PULL ELECTROSTATIC LOUDSPEAKER

A model is being developed for the electrostatic loudspeaker, which in corporates simultaneously the mechanical, acoustical, and electrical b ehavior of the diaphragm. The nonlinear model can be solved fairly acc urately in the steady state and is used for calculating the frequency- and level-dependent sensitivity and distortion for an infinite-strip push-pull electrostatic loudspeaker. The results are compared with pre viously published and new improved small-signal approximations.
