<p>The present invention relates to a haptic actuator, and in particular, to a haptic actuator incorporated in an electronic device, which needs to generate vibration, such as a mobile terminal so as to generate vibration by the interaction of a coil and a magnet. According to the haptic actuator of the present invention, if the direction of a current applied to a coil changes, a vibration part provided with a vibration part side permanent magnet elastically deforms a vibration plate and vibrates in the vertical direction by the attractive force or repulsive force between each of the mutual magnetic fields generated via the core disposed in the center of the coil and generated at the vibration part side permanent magnet.</p> |
