Abstract
To provide an electromechanical signal selection device which can be miniaturized and highly integrated and which can selectively output only a signal of a predetermined frequency without providing any sensitive vibration sensing mechanism, and electric equipment using the electromechanical signal selection device. A micro-vibrator serving as a resonator is provided. The micro-vibrator can be excited by an external force to excite vibration of the micro-vibrator. A material whose physical property is changed in accordance with a structural change is used as the micro-vibrator. Thus, a sensitive electromechanical signal selection device is obtained.
Claims27
An electromechanical signal selection device comprising:
- a micro-vibrator which can be excited by an input signal;
- and
- a post for retaining the micro-vibrator,
- wherein the micro-vibrator can generate a change in physical property due to excitation so as to select a selected signal.
