Abstract
A technology for improving a device structure so that an external impact does not occur in a coil in order to solve a problem in that several attachments, such as coil, included in a linear vibration generator are separated or broken due to a small impact test or drop test on the linear vibration generator. The attachments, such as coil, included in the linear vibration generator can be prevented from being disconnected, separated or broken due to the execution of a small impact test and drop test on the linear vibration generator.
