DUAL BAND MEMS ACOUSTIC DEVICE |
| 摘要 |
A device includes a first microelectromechanical systems (MEMS) transducer, a second MEMS transducer and a summing device. A first dimension of the first MEMS transducer is predefined to configure the first MEMS transducer to have a first resonance frequency. A second dimension of the second MEMS transducer is predefined to configure the second MEMS transducer to have a second resonance frequency different than the first resonance frequency. The summing device is coupled to the first MEMS transducer and the second MEMS transducer and provides an output representing a combination of information from the first MEMS transducer and the second MEMS transducer. |

1. A microelectromechanical systems (MEMS) acoustic device, comprising:
a first MEMS transducer including a first diaphragm and a first back plate, wherein at least one of the first diaphragm and the first back plate has a first dimension; and a second MEMS transducer including a second diaphragm and a second back plate, wherein at least one of the second diaphragm and the second back plate has a second dimension, and wherein a magnitude of the second dimension is less than a magnitude of the first dimension. |
