Title:
二次元共鳴振動モーター
Document Type and Number:
Japanese Patent JP5224209
Kind Code:
B2
Abstract:
A vibration generator has an oscillator including a magnet and a holding member for holding the oscillator based on a magnetic force emitted from the oscillator. The holding member includes a magnet or a magnetic body. The oscillator vibrates relative to the holding member. A magnetic force between the oscillator and the holding member defines a natural period of vibration of the oscillator relative to the holding member. When a periodic current is supplied to an electromagnetic coil fixed to the holding member, the oscillator vibrates relative to the holding member so as to synchronize with the period of the periodic current. By synchronizing the period of the periodic current with a natural period, the oscillator resonates.
