Abstract

A vibration-generating device includes a motor stored in a housing such that a rotating shaft projects from the housing. A weight is attached to the rotating shaft and a coil spring which serves as an elastic member is wound around the rotating shaft. One end of the coil spring is attached to a shaft and the other end to a restraining projection. When the rotating shaft and the weight reciprocate, the housing vibrates due to an impact which occurs every time the moving direction of the weight is reversed. When a stepping motor is used, an impact occurs and damping vibration is generated due to the impact when a driving pulse is applied to control the motor. Accordingly, the housing vibrates due to this impact or the damping vibration. In addition, rotation control is easily performed and various vibrations are obtained by changing the vibration frequency and amplitude.

Description

technical field [0001] The present invention relates to a vibration generating device arranged in a portable device and the like to apply vibration to the portable device, and more particularly to a vibration generating device with variable vibration and an electronic device equipped with the device. Background technique [0002] A vibration generating device that generates vibration in a case is generally disposed in a controller for playing a video game or the like. By disposing such a vibration generating device, the case can be vibrated according to the state of the game, and the player can feel the vibration to enhance the sense of immersion in the game. [0003] This kind of vibration generating device is equipped with a hammer (weight) that can perform eccentric movement on the rotating shaft of a DC motor with a brush or a hollow motor, and the vibration of the motor is formed by the centrifugal force obtained by rotating the hammer, so that the box The body vibrate...
