VIBRATION WAVE DETECTOR |
摘要 |
A vibration wave detector having a first diaphragm for receiving vibration waves, such as sound waves and so on, to be propagated in a medium, a resonant unit having a plurality of cantilever resonators each having such a length as to resonate at an individual predetermined frequency, a retaining rod for retaining the resonant unit, a second diaphragm positioned on the opposite side of the first diaphragm with respect to the retaining rod, and a vibration intensity detector for detecting the vibration intensity, for each predetermined frequency, of each of the resonators, by the vibration waves received by the first diaphragm and propagated to the resonant unit through the retaining rod.
