Abstract
An analytical model is developed that describes the behavior of a dome-shaped piezoelectric loudspeaker. The loudspeaker consists of a PVDF circular membrane coupled with a rear cylindrical cavity. The dome shape is obtained by means of a static differential pressure held between the
two faces of the membrane. The theoretical description of the transducer's behavior is conducted in two steps. In the first step, the static behavior of the membrane is studied in order to obtain the profile of the membrane when submitted to a static differential pressure. In the second step,
the dynamic behavior of the membrane is studied. Finally, the theoretical results obtained are compared with experiments in order to evaluate the accuracy of the model.
