Abstract:
A linear actuator may include a movable element having a plurality of permanent magnets stacked in a direction of an axis line; a stationary element comprising a plurality of coils surrounding a circumferential section of the permanent magnets, the plurality of coils being placed along the axis line; and viscous elastic members inserted between the movable element and the stationary element. The plurality of permanent magnets are arranged such that, among adjacent permanent magnets of the plurality of permanent magnets, sides of the adjacent permanent magnets facing each other have a same polarity. The viscous elastic members are provided at a plurality of locations being separate in the direction of the axis line, in a space sandwiched in a radial direction by the movable element and the stationary element.

Claim (Index 13):
A device for notifying of information by way of a vibration, the device comprising:\n a linear actuator for generating the vibration; the linear actuator comprising:\n a movable element comprising a plurality of permanent magnets stacked in a direction of an axis line; \n a stationary element comprising a plurality of coils surrounding a circumferential section of the permanent magnets, the plurality of coils being placed along the axis line; and \n viscous elastic members inserted between the movable element and the stationary element; \n wherein, the plurality of permanent magnets are arranged such that, among adjacent permanent magnets of the plurality of permanent magnets, sides of the adjacent permanent magnets facing each other have a same polarity; and \n the viscous elastic members are provided at a plurality of locations being separate in the direction of the axis line, in a space sandwiched in a radial direction by the movable element and the stationary element; \n wherein the stationary element comprises a case having a torso part surrounding a circumferential section of the external yoke; and \n wherein, the case comprises a bottom plate part at either one of the one side and the other side in the direction of the axis line; and in the bottom plate part, there is provided a sounding hole that discharges a pressure change, in accordance with a vibration of the movable element in the direction of the axis line, as an audible level sound; with regard to a signal waveform to be applied to the coils, a frequency is modified according to information to be transmitted; a user holding the linear actuator with hand can obtain information by way of a vibration from the linear actuator and can furthermore obtain information by way of the sound discharged from the sounding hole.
