    摘要： A small-size, thin-profile vibration generating device capable of functioning with improved durability and reliability and with less consumption of power includes a yoke constituting an electromagnet on which a coil has been wound, and a movable element having permanent magnets. The movable element is disposed in a gap, which is provided in the closed magnetic circuit of the yoke, in such a manner that both end faces of the movable element form prescribed gaps with end faces of the yoke. The movable end of a leaf spring is attached to the movable element. The other, fixed end of the leaf spring is attached to the center of the yoke. When the movable element vibrates in the gap, magnetic poles at the end faces of the yoke approached by the end faces of the movable element are magnetically energized by flow of a current in order to be made identical with magnetic poles at the end faces of the movable element, thereby repelling the movable element. The result is that vibration is produced at a prescribed oscillation frequency.

    摘要： A vibration generator which is durable, provides strong thrust and is capable of being reduced in size, cost and weight includes a movable element (50) having a permanent magnet (60) attached thereto; a stationary element (10) having end faces (23), (25) which oppose, across prescribed gaps, respective ones of end faces (53), (54) of the movable element, with the stationary element being excited by passing a current through an attached coil (30) to form a magnetic path with the movable element; and resilient support members (80) for supporting the movable element so that the movable element can vibrate in a direction in which the stationary element is magnetized by the coil. One pole face of the permanent magnet is arranged to oppose the outer side of the coil, thereby forming a magnetic path in which magnetic flux that emerges from the pole face of the permanent magnet cuts across the outer peripheral side of the coil, penetrates the interior of the coil and then is guided in the direction of N and S poles of the coil. The end faces of the stationary element are excited to desired magnetic poles to thereby vibrate the movable element.
