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.

Abstract: A mechanical resonant system includes a voice coil actuator, a payload mass (110A,110B), a driver mass (120A,120B,120C) and a frame mass (130A,130B,130C). The voice coil actuator includes a bobbin (160), an electrical conductor (170) and a magnet assembly (180,190). The bobbin is made from a material that is electrically nonconductive. The electrical conductor is coupled to the bobbin. The magnet assembly has a housing (180) and a magnet (190) coupled to the housing. At least a portion of the bobbin (160) and at least a portion of the electrical conductor (170) are configured to be positioned within a gap formed by the magnet (190) and the housing (180). The bobbin and the magnet assembly are configured to oscillate when an alternating current is applied to the electrical conductor. The payload mass (110A,110B) is coupled to one of the bobbin and the housing. The driver mass (120A,120B,120C) is coupled to the other of the bobbin and the housing.
