Title:
HAPTIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2016/010180
Kind Code:
A1
Abstract:
The present invention relates to a haptic actuator for further enhancing performance such as a response speed to a user's touch and a frequency band by improving a magnetic structure. A vibration body comprises: a first magnetic body arranged at one end of a coil member in the longitudinal direction thereof; a second magnetic body arranged at the other end of the coil member in the longitudinal direction thereof; first and second magnets mounted to both ends of the first magnetic body respectively in the transverse direction thereof; third and fourth magnets mounted to both ends of the second magnetic body respectively in the transverse direction thereof; a third magnetic body mounted to one end of the first magnet and the third magnet in the transverse direction thereof; a fourth magnet body mounted to the other end of the second magnet and the fourth magnet in the transverse direction thereof; and first and second weights mounted to the third magnetic body and the fourth magnetic body respectively.
