摘要:
An oscillator device includes a first oscillator, a second oscillator configured to support the first oscillator for torsional rotation about a first rotational axis, through a first torsion spring, a supporting member configured to support the second oscillator for torsional rotation about a second rotational axis, through a second torsion spring, the second rotational axis having a predetermined angle with respect to the first rotational axis of the first oscillator, a coil disposed in relation to the second oscillator, an electrical current applying member configured to apply an electrical current to the coil, and a magnetic field generating member configured to apply a magnetic field to the coil. The coil is localized in at least one of zones of the second oscillator being quartered by extension lines of the first and second rotational axes.
