Abstract:
An oscillator device includes an oscillation system having a first oscillator, a second oscillator, a first resilient supporting member and a second resilient supporting member, wherein the oscillation system has at least two frequencies of natural oscillation mode around the torsion axis which include a first resonance frequency f1 and a second resonance frequency f2, wherein there is a relationship that f2 is approximately two-fold of f1, wherein Δf which is expressed as Δf=f2−f×f1 has a relationship of Δf f2 and Df1×2=Df2.
