摘要： A micrometric speaker includes a frame, an electromechanical transducer, and a mechanical-acoustic transducer comprising a rigid plate movably mounted in the frame. The electromechanical transducer comprises two piezoelectric actuators and two elastic strips. The frame comprises a central crossmember from which the two strips extend until engaging two lateral coupling edges of the mechanical-acoustic transducer, and the mechanical-acoustic transducer comprises two linearising springs each extending from one of the lateral edges to the rigid plate, to enable, during a deformation of the strips, a movement of the two lateral edges to the central crossmember and reduce the longitudinal constraints applied to the strips during their deformation due to their “recessed-guided” bending configuration.
