Title:
VIBRATION GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/013085
Kind Code:
A1
Abstract:
This vibration generating device is provided with a housing, a vibrating body which is housed in the housing, an elastic support unit which supports the vibrating body so as to allow vibration in a first direction and a second direction that intersect each other, and a magnetic drive unit which drives the vibrating body using magnetic force in the first direction and the second direction. The magnetic drive unit includes a first magnetic field generating means which is arranged on the vibrating body side, and a second magnetic field generating means which is arranged on the housing side so as to be positioned on the line of extension of the vibrating body in a third direction perpendicular to the first direction and the second direction, wherein the elastic support unit has a fixed part along the third direction, and, on the housing, a fixing part is formed which fixes the fixed part of the elastic support unit and which extends in the third direction and permits a range of positions in the third direction for the attachment of the elastic support unit to the housing along the third direction.
