APPARATUS FOR GENERATING MECHANICAL OSCILLATIONS AND A METHOD FOR DETERMINING THE RESONANCE FREQUENCY OF SUCH APPARATUS |
| 摘要 |
A device for generating mechanical oscillations is provided. The device has a first mass, a second mass, and a piezoelectric excitation system mechanically coupling the first mass and the second mass to one another, with the piezoelectric excitation system having a stiffness. The piezoelectric excitation system is designed such that its stiffness is settable. |
