Document Type and Number:
WIPO Patent Application WO/2023/234293
Kind Code:
A1
Abstract:
This vibration actuator has: a movable stacked body including a magnet and a pair of yokes which are respectively fixed to the front surface and the rear surface of the magnet and have openings in the center; a fixed body which has a coil and supports the movable stacked body on the inside of the coil with a pair of elastic support parts in a state in which the movable stacked body can reciprocate and vibrate in an axial direction; and a pair of connection parts each having a cylindrical member and a shaft member which is inserted into the cylindrical member and has a flange on the base end thereof. While the leading ends of the shaft members are in contact with the front surface or the rear surface of the magnet in the openings of the pair of yokes, the pair of connection parts cause the movable stacked body to be connected to the pair of elastic support parts by clamping the pair of elastic support parts by means of the flange of the shaft members and the base end-side end surface of the cylindrical member.
