Abstract:
A micromechanical component including a mounting including a spanned diaphragm, which is warpable via a pressure difference between a first diaphragm side and a second diaphragm side against a diaphragm counter force according to a diaphragm spring constant of the diaphragm, and at least one actuator electrode, which is connected to the diaphragm and adjustable against a spring force according to at least one spring constant of at least one spring with the aid of a warping of the diaphragm, an overall system spring constant being definable as the sum of a diaphragm spring constant of the diaphragm and the spring constant of the single spring, or an overall spring constant of all springs, via which the at least one actuator electrode is connected to the mounting, and the spring constant of the single spring or of all springs being at least 5% of the overall system spring constant.
