Abstract

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.

Description

technical field [0001] The present invention relates to a vibrating device, more particularly, to a vibrating device that increases the amount of vibration by applying a three-dimensional elastic member, increasing the size of a counterweight supported by the elastic member, and to a vibrating device, It increases the amount of vibration by making a larger magnetic force generating member, which is supported by an elastic member. Background technique [0002] Generally, mobile communication terminals, such as portable phones, pagers and PDAs, use vibrating devices to send a vibration to the user in addition to the sound of a ringtone when receiving a message or a call. [0003] figure 1 is a cross-sectional view of a conventional vibrating device, while figure 2 is a perspective view of a leaf spring used in a conventional vibrating device. [0004] like figure 1 Shown, conventional vibration device comprises a lower case 20, a coil 30 installed in the middle part of lo...
