Title:
LINEAR ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2018/030264
Kind Code:
A1
Abstract:
A linear actuator 1 that has: a mobile body 6; a fixed body 2 that comprises a case 3 in which the mobile body 6 is housed; and a magnetic drive mechanism 10 that drives the mobile body 6 in an axial line L direction. A sound emission hole 360 that emits pressure changes that accompany the vibration of the mobile body 6 in the axial line L direction as audible sound is provided in a bottom plate part 36 that is on one side L2 of the case 3 in the axial line L direction. When the magnetic drive mechanism 10 makes the mobile body 6 vibrate in the axial line L direction, the vibrations are transmitted to a user. Information can be transmitted by means of the vibrations by switching the form of the vibrations in accordance with the information to be transmitted. Information can be transmitted by means of sound because sound that accompanies the vibrations of the mobile body 6 in the axial line L direction can be outputted from the sound emission hole 360.
