MICRO-ELECTRO-MECHANICAL ACOUSTIC TRANSDUCER DEVICE WITH IMPROVED DETECTION FEATURES AND CORRESPONDING ELECTRONIC APPARATUS

摘要

Described herein is a MEMS acoustic transducer device provided with a micromechanical detection structure that detects acoustic-pressure waves and supplies a transduced electrical quantity, and with an integrated circuit operatively coupled to the micromechanical detection structure and having a reading module that generates at output an audio signal as a function of the transduced electrical quantity. The integrated circuit is further provided with a recognition module, which recognizes a of sound activity event associated to the transduced electrical quantity. The MEMS acoustic transducer has an output that supplies at output a data signal that carries information regarding recognition of the sound activity event.
