Abstract
A micromechanical component for a sound transducer device. The component includes a diaphragm element which includes a first diaphragm surface and a second diaphragm surface which points away from the first diaphragm surface, and at least one piezoelectric element situated on and/or at the first diaphragm surface. The micromechanical component includes a substrate having at least one control and/or evaluation circuit developed thereon and/or therein, the first diaphragm surface pointing toward the substrate, and the substrate is attached to the diaphragm element at least via at least one an electrically conductive bond connection structure which is developed on and/or at the first diaphragm surface, from which the second diaphragm surface is pointing away, and the at least one piezoelectric element is electrically connected to the at least one control and/or evaluation circuit at least via the at least one electrically conductive bond connection structure.
