Abstract
A haptic generator in accordance with an embodiment of the present disclosure may include a driving signal generator and a haptic device. The driving signal generator may be configured to receive a sound signal and generate a driving signal including an impact driving signal and an inertia driving signal. The haptic device may be configured to generate impact vibrations pursuant to the impact driving signal and generate rotational inertia vibrations pursuant to the inertia driving signal, the rotational inertia vibrations being different from the impact vibrations. The impact driving signal and the inertia driving signal may be generated based on different properties of the sound signal.
Claims13
A haptic generator, comprising:
- a driving signal generator configured to receive a sound signal and generate a driving signal, the driving signal comprising an impact driving signal and an inertia driving signal;
- and
- a haptic device configured to output an haptic effect pursuant to the driving signal,
- wherein the haptic device comprises:
- a stator unit including a stopper;
- and
- a rotor unit including a protrusion and configured to rotate about the stator unit, wherein the rotor unit is configured to rotationally reciprocate within a range of 360 degrees,
- wherein the haptic device is configured to generate impact vibrations pursuant to the impact driving signal and generate rotational inertia vibrations pursuant to the inertia driving signal, and
- wherein the impact driving signal and the inertia driving signal are generated based on properties of the sound signal that are, respectively, different from each other.
A method of driving a haptic generator, comprising:
- receiving a sound signal;
- analyzing various properties of the sound signal;
- and
- generating an impact driving signal and an inertia driving signal based on a plurality of different properties of the sound signal,
- wherein the haptic generator comprises a haptic device configured to generate impact vibrations caused by a collision of a stopper and a protrusion pursuant to the impact driving signal and generate rotational inertia vibrations by forcing the protrusion to stop rotating before colliding with the stopper or by reversing the rotation of the protrusion pursuant to the inertia driving signal.
