Title
(DE) Mikrofonvorrichtung mit Beschleunigungssensor zum Schwingungsausgleich
(EN) Microphone device with accelerometer for vibration compensation
(FR) Dispositif de microphone avec accéléromètre pour compensation de vibrations
Abstract
(EN) A microphone and a method for manufacturing the same is presented. The microphones comprises a substrate die (24); and a microphone (20) and an accelerometer (22) formed from the substrate die. The accelerometer is adapted to provide a signal for compensating mechanical vibrations of the substrate die.
