Kind Code:
A
Abstract:
To provide a vibration actuator that is downsized and stably generates different vibration output with various frequency bands.SOLUTION: A vibration actuator has an enclosure and a magnet part; has a first movable part arranged to be freely reciprocatable, in a vibration direction along an axial direction in the enclosure, through a first elastic support part jointed to both end parts separated in the axial direction of the magnet part, and a coil part arranged concentrically with the magnet part to surround the magnet part; and has a second movable part arranged to be freely reciprocatable, in the vibration direction in the closure and in an outer periphery of the first movable part, through a second elastic support part jointed to both end parts separated in the axial direction of the coil part, which moves the first movable part and the second movable part by distributing electricity to the coil part to generate vibrations.SELECTED DRAWING: Figure 4
