Problems solved by technology

[0009] However, since the piezoelectric element should be relatively long to ensure displacement and vibration, the length of the vibration generating device is increased, and the vibration generating device is easily damaged in the event of an impact when the vibration generating device is dropped
[0010] That is to say, this vibration generating device has an approximately rectangular parallelepiped shape and has a relatively elongated form, so that it is difficult to miniaturize this vibration generating device, and such a piezoelectric element with an elongated form is easily damaged due to external impact

Abstract

There is provided a vibration generating apparatus including: a bracket having a circular plate shape; a vibration member having a lower edge portion of a central portion fixed to the bracket and having a closed curved line shape; a piezoelectric element fixed to a lower surface of the vibration member among inner surfaces of the vibration member and deformed when power is applied thereto; and a mass body fixed to the inner surfaces of the vibration member and disposed to face the piezoelectric element.

Description

[0001] This application claims Korean Patent Application No. 10-2013-0039080 filed with the Korean Intellectual Property Office on April 10, 2013 and Korean Patent Application No. 10-2014-0040454 filed with the Korean Intellectual Property Office on April 4, 2014 Interest in patent application, the disclosures of said two Korean patent applications are hereby incorporated by reference. technical field [0002] The present disclosure relates to a vibration generating device. Background technique [0003] Vibration generating devices that convert electrical energy into mechanical vibrations using the generation principle of electromagnetic force have been installed in mobile phones and the like for silently notifying a user of an incoming call by transmitting vibration to the user. [0004] Furthermore, according to the rapid development of the market of mobile devices such as mobile phones, various functions have been added to the mobile devices. In addition, mobile devices ...
