Title: VIBRATION DEVICE, WEARABLE TERMINAL AND INCOMING CALL NOTIFICATION DEVICE
Abstract:
A vibration device capable of appropriately imparting a large sensible vibration without an increase in the size of vibration actuators. Said vibration device, which is provided with vibration actuators with which a moving body elastically supported on a fixed body can be vibrated linearly with respect to the fixed body at a resonance frequency, has a mounting case in which multiple vibration actuators are mounted. The multiple vibration actuators oscillate at roughly the same resonance frequency, and in a manner such that the respective oscillation axis lines along the oscillation directions of the moving bodies are parallel to each other and that the center of gravity of the mounting case is interposed between the oscillation axis lines, the vibration actuators are disposed in orientations according to which the actuators excite oscillations in mutually opposite directions on the respective oscillation axis lines.
