Title:
VIBRATION GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/029117
Kind Code:
A1
Abstract:
A vibration generating device (101) comprises: a housing (HS), a vibrator (VB) housed in the housing (HS), an elastic support member (ES) that supports the vibrator (VB) so as to be capable of vibrating along the X-axis direction, a coil (12) having a bundle wire part extending along the Y-axis direction, and a magnet (15) that generates a magnetic flux passing through the bundle wire part along the Z-axis direction. In addition, the vibration generating device (101) is configured such that the coil (12) is fixed to the housing (HS) and the magnet (15) is fixed to the vibrator (VB). Moreover, the vibration generating device (101) comprises a bracket (11) as a conductive member fixed to the coil (12), extending along the X-axis direction across the magnetic flux, and configured to generate an eddy current and reduce the acceleration of the vibrator (VB) when the vibrator (VB) moves along the X-axis direction.
