20150357958 | Control Method For Vibration Generator And Vibration Generator - A control method for a vibration generator is provided. The vibration generator includes a fixed part around which a coil is wound, a movable part having a magnet, a bridge part movably supporting the movable part, and a power supply unit which applies an alternating current of a predetermined frequency to the coil. The power supply unit starts at the time of startup by the alternating current with a starting frequency which differs from a resonance frequency of the movable part, and the power supply unit changes the frequency of the applied alternating current to the resonance frequency of the movable part when the amount of vibration at the starting frequency reaches a predetermined ratio with respect to a saturation vibration amount of the resonance frequency. | 12-10-2015 |
