Discrete MEMS Including Sensor Device |
| 摘要 |
A micro electro mechanical system (MEMS) microphone includes a base; a MEMS device disposed on the base, the MEMS device comprising a diaphragm and a back plate; a condition sensor disposed on the base; and an integrated circuit coupled to the condition sensor and the MEMS device. The MEMS device operates to detect acoustic signals in a first frequency range and the condition sensor acts as a condition sensor in the first frequency range. The condition sensor acts as a microphone in a second frequency range and the MEMS device is unused so as to extend the operating range and acoustic overload point of the MEMS device. |
