    • Disclosed is a vibration device in which an elastic unit is formed on upper and/or lower surface of a weight, and the weight for generating vibration is extended in a circumferential direction. Also, a vibration device with a sound function, which gives an improved vibrating amount by making a larger magnetic force generating unit to be supported by elastic units, is also disclosed. Thus, the vibration device may be made in a smaller size, and therefore it enables miniaturization of a mobile communication terminal in which such vibration device is usually mounted.
    • 公开了一种振动装置,其中弹性单元形成在重物的上表面和/或下表面上,并且用于产生振动的重量在圆周方向上延伸。 此外,还公开了一种具有声音功能的振动装置,其通过使较大的磁力产生单元由弹性单元支撑而提供改善的振动量。 因此,振动装置可以制造成较小的尺寸,因此能够使通常安装这种振动装置的移动通信终端的小型化。
