Abstract
A vibration generator includes a coil, a vibrating body, a spring, and a shaft. The coil is arranged to generate magnetic fields. The vibrating body includes a magnet and a weight. The vibrating body is arranged to be vibrated in a thrust direction by an interaction of magnetic fields generated from the magnet and magnetic fields generated from the coil. The spring is arranged to support the vibrating body at one thrust-direction side of the vibrating body. The shaft is extended in the thrust direction through the vibrating body. The shaft is arranged to allow the vibrating body to slide along the shaft in the thrust direction.
