Zusammenfassung:	The present invention relates to a device for generating vibration in a portable terminal with a disk shape. For this, a device for generating vibration according to the present invention includes: a diaphragm made of a metallic material; a piezoelectric plate installed to at least one side of the diaphragm; and a fixing member which is combined with the edge of the diaphragm and fixes the diaphragm. The fixing member may be made of a material which has Youngs modulus smaller than that of steel. 본 발명은 원반 형상으로 형성되는 휴대 단말용 진동 발생 장치에 관한 것이다. 이를 위한 본 발명에 따른 진동 발생 장치는, 금속 재질로 형성되는 다이어프램(diaphragm); 상기 다이어프램의 적어도 어느 한 면에 장착되는 압전 플레이트; 및 상기 다이어프램의 외곽을 따라 체결되어 상기 다이어프램을 고정하는 고정 부재;를 포함하며, 상기 고정 부재는 강철(Steel)보다 영률(Young's Modulus)이 작은 재질로 형성될 수 있다.
