Resonant devices

A resonant device is a vibration device that utilizes mechanical resonance, with voice coils or electromagnetic core as the main power source. It is a high-reliability and wide-range actuator that enables a variety of vibration expressions and tactile feedback. It has a fast response speed and can achieve realistic tactile sensations that were not possible with conventional rotating vibration motors. For example, it can vividly express sensations such as smoothness, roughness, the feeling of shaking a bottle filled with water, and the sensation of pressing a button, as if experiencing them in real life.
