MEMS microphone system with low pressure gap and back volume
A MEMS microphone system comprises a transducer die having a pierce-less diaphragm and a motion sensor suspended from the diaphragm. The system further comprises a housing and the diaphragm divided a volume inside the housing into a front volume and a back volume. The motion sensor suspended from th...

| description | A MEMS microphone system comprises a transducer die having a pierce-less diaphragm and a motion sensor suspended from the diaphragm. The system further comprises a housing and the diaphragm divided a volume inside the housing into a front volume and a back volume. The motion sensor suspended from the diaphragm is located in the back volume having a gas pressure that is substantially equal or lower than an ambient pressure. |
