Spring structure, resonator, resonator array and sensor
First Claim
1. A spring structure, comprising:
- at least two masses coupled in a first direction as opposite phase oscillators using springs connected to the masses, via a u-shaped member between said springs and connected to coupling points of the springs, wherein oblique springs are connected from said coupling points to anchors of base such that longitudinal motion of the u-shaped member is configured to occur perpendicularly to or substantially perpendicularly to said first direction, to thus attenuate in-phase oscillation and enable opposite phase oscillation of the masses, wherein the oblique springs are oblique with respect to both the springs and the u-shaped member.

Abstract
The invention presents a spring structure (501), which has at least two masses (Ma, Mb) coupled in a first direction as opposite phase oscillators by means of springs (Sh1, Sh2) connected to them (Ma, Mb), via a loop (L, E) between said springs (Sh1, Sh2) connected to their coupling points, wherein oblique springs (Sl45, Sr45) are connected from said coupling points of the loop (L) to the anchors (A) of the base such that the longitudinal motion of the loop (L) is arranged to occur perpendicularly or substantially perpendicularly to said first direction, to thus attenuate opposite phase oscillation other than that of the masses (Ma, Mb). The invention also presents the use of a spring structure in a resonator and/or in a resonator array as well as in a sensor or a sensor comprising system.
