Abstract

Disclosed herein is a piezoelectric vibration module including a vibration plate that is surrounded by an upper case and a lower case, and includes a first stopper capable of preventing direct collision between a piezoelectric element and an internal constituent member, for example, an upper plate while vibrating linearly therein. In particular, the piezoelectric vibration module may further include a second stopper in the lower case.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2012-0048709, filed May 8, 2012, entitled "Piezoelectric Vibration Module," the entire contents of which are hereby incorporated by reference in this application. technical field [0003] The invention relates to a piezoelectric vibration module. Background technique [0004] In portable electronic devices such as portable phones, electronic book (E-book) terminals, game machines, PMPs, etc., vibration functions are commonly used for various purposes. [0005] Especially on the portable electronic device, a vibration generator for generating vibrations is basically installed, so as to serve as a reminder function for silently receiving signals. [0006] Due to the multifunctional implementation of portable electronic devices, vibration generators actually require miniaturization, integration, and various advanced functions at present. [0007] In a...
