Title:
VIBRATION GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/137981
Kind Code:
A1
Abstract:
A vibration device (101) comprises a coil (4) and a magnetic flux source (5). The magnetic flux source (5) includes a left-side magnet (5L), a first center magnet (5C1), a second center magnet (5C2), and a right-side magnet (5R). The coil (4) includes: a left-side coil (4L) formed of a left-side wire bundle (4U1L) and a right-side wire bundle (4U1R); and a right-side coil (4R) formed of a left-side wire bundle (4U3L) and a right-side wire bundle (4U3R). The number of magnetic fluxes that are generated by the first center magnet (5C1) and that vertically penetrate through a space (SP1) between the right-side wire bundle (4U1R) of the left-side coil (4L) and the first center magnet (5C1) is smaller than the number of magnetic fluxes that are generated by the left-side magnet (5L) and that vertically penetrate a space (SP2) between the left-side wire bundle (4U1L) of the left-side coil (4L) and the left-side magnet (5L).
