摘要： The invention relates to an electro-acoustic transducer, particularly an ultrasonic transducer, comprising a plurality of electrostatic micro-cells of the cMUT type. The electrostatic micro-cells are arranged in homogeneous groups of micro-cells having the same geometrical characteristics. The micro-cells of each group have geometries different from the geometry of the micro-cells of the other group or groups.
