Abstract
Provided herein is a mechanical resonant system, comprising a frame; at least one pump disposed on the frame; one or two masses coupled to the frame by a first plurality of resilient members; and at least one voice coil actuator disposed within the frame and coupled to the at least one pump or to the one or two masses; wherein when the system comprises two masses, a second plurality of resilient members couple the masses to each other. Also provided are methods for using these mechanical resonant systems to evacuate a chamber, to compress air, or sense changes in pressure.
