Abstract
A curved haptic actuator according to an embodiment may comprise: a housing having a receiving space and having a shape where the receiving space and an outer appearance thereof are bent outward; a vibration unit disposed in the receiving space, being movable along the longitudinal direction of the housing, and having a shape bent upward; elastic bodies connected to an inner wall of the housing and both sides of the vibration unit; and a magnetic field generation unit which is installed on the inner wall of the housing and generates a magnetic field and applies the magnetic field to the vibration unit.
Claims19
A curved haptic actuator comprising:
- a housing having a receiving space defined in the housing, wherein the receiving space and an outer shape of the housing are curved in a set curvature;
- a vibrator disposed in the receiving space;
- and
- each elastic body connected between each of both side surfaces of the vibrator and an inner wall of the housing,
- wherein the vibrator is movable along a direction of the set curvature, but moves such that the vibrator does not come into contact with the inner wall of the housing, and
- wherein a distance between the vibrator and the inner wall of the housing closest to the vibrator is greater than 0 mm and less than 3 mm.

A wearable device comprising:
- a main body;
- a strap connected to the main body, at least a portion of the strap having a curved shape of a set curvature;
- and
- a first curved haptic actuator installed in a curved portion of the strap,
- wherein the first curved haptic actuator includes:
- a first vibrator movable along a longitudinal direction of the strap and having a curved shape of the set curvature;
- and
- a first magnetic field generator for generating a magnetic field to be applied to the first vibrator,
- wherein the first vibrator is movable along a direction of the set curvature, but moves such that the first vibrator does not come into contact with the inner wall of the strap, and
- wherein a distance between the first vibrator and the inner wall of the strap closest to the first vibrator is greater than 0 mm and less than 3 mm.
