Abstract
The present invention relates to an improved vibration cancellation device designed to overcome many of the shortcomings inherent in prior devices. In many embodiments, the vibration cancellation device is smaller in scale than prior designs, facilitating more versatility with respect to design options. The device of the present invention achieves a smaller size partly due to the use of suspension springs having an offset, rather than a parallel arrangement.
