Disclosed is a vibration module for a portable terminal that includes a housing, a magnetic moving part movable in a first direction within the housing; an elastic member supported between the opposite ends of the magnetic moving part and inner walls of the housing, and a solenoid coil provided in the housing. The vibration module is positioned at one end of the moving section by the magnetic force of the magnetic moving part and an object around the magnetic moving part, allowing the vibration module to provide a user with a feeling similar to a click feeling via the acceleration produced at a stopping instant. In addition, when vibrating, the vibration module generates sufficient vibration power through acceleration at the instant of changing moving direction at the ends of the moving section, to provide an alarm function, such as an incoming call notification.

Vibration module for portable terminal

A tactile display apparatus includes a plurality of stimulation pins in contact with a skin; an operating unit for vertically moving the stimulation pins; and a housing accommodating the stimulation pins and the operating unit, the housing having an opening in one surface thereof such that the stimulation pins protrude outward. Here, the plurality of stimulation pins are arranged such that a contact area occupied by front ends of the stimulation pins is smaller than an area occupied by rear ends of the stimulation pins.

Tactile display apparatus and method thereof

A haptic module using a magnetic force and an electronic apparatuses having a magnet arrangement frame arranged so that polarities of adjacent magnets are alternate; shielding screens positioned on uppers of each of frame elements of the magnet arrangement frame and formed in a window arrangement to shield any one polarity of the frame elements; linear movement apparatus fixed to outside portions of the shielding screens to move the shielding screens in a longitudinal direction of the frame element; a magnet frame positioned on an upper of the magnet arrangement frame through the shielding screen and taking on the same polarity on the whole of one surface thereof; and a controller that controls the linear movement apparatus to provide various and dynamic force feedback and tactile sensation to a user, as well as reduce complexity of a constitution as compared to a related art and further accomplish miniaturization.

Haptic module using magnetic force, electronic apparatuses having the module

The present invention discloses a tactile feedback device for giving realistic touch sensation to the user by stimulating the skin of the user. The tactile feedback device of the present invention comprises a housing having one end positioned near the skin of the user in use, an actuator, touch pins and an elastic means. The actuator is mounted inside the housing to convert electromagnetic energy into kinetic energy. The touch pins are mounted inside the housing so as to pop in and out, and the front end thereof is popped out of one end of the housing to contact the skin, and is connected with the actuator so as to be operated by kinetic energy of the actuator. The elastic plates of the elastic means are mounted between one end of the housing and the actuator, and have the touch pins fixedly passing through so as to be interlocked with the touch pins, and when the touch pins pop in and out, they are elastically deformed to have elastic energy. According to the present invention, the touch pins stimulate the skin of the user by dint of an interlocking structure of the actuator that converts electromagnetic energy into kinetic energy and the elastic means, so it is possible to implement realistic touch sensation.
