Problems solved by technology

[0012] However, if the counterweight 50 becomes thicker, the size of the magnet 40 becomes smaller; although the weight of the counterweight 50 increases, the amount of vibration generated by the interaction between the magnet 40 and the coil 30 will be further reduced.
[0013] Also, if the weight is expanded in the circumferential direction to increase the amount of vibration, the length of the leaf spring 60 formed between the weight 50 and the spring holder 70 is reduced, thereby causing a reduction in the elastic force.

Abstract

Disclosed is a vibration device, comprising an upper, lower and side surface cases; a weight in the case and comprising at least one magnetic body; at least one elastic unit for elastically supporting the weight and contacting with the cases; a magnetic force generating unit for generating magnetic force to perform vibration weight in the cases; wherein the distance between the side surface of the weight and the side surface of the case is less than the distance between the contact section of at least one elastic unit and case and the side surface of the case.

Description

[0001] This application is a divisional application of the invention application with the international filing date of July 1, 2004, the international application number PCT / KR2004 / 001615, the national application number 200480000815.4, and the name "vibration device". technical field [0002] 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 [0003] 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. [0004] figure 1 is a cross-sectional...
