Abstract

There is provided an apparatus for generating vibrations, the apparatus including: a lower case made of a non-magnetic material; a coil plate mounted on the lower case and made of a magnetic material so as to reduce magnetic force leakage; a coil mounted on the coil plate; and a motion element including a magnet disposed to be opposite to the coil such that an electromagnetic force is generated by interaction with the coil.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2011-0007272 filed with the Korean Intellectual Property Office on Jan. 25, 2011, the disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a device for generating vibration, and more particularly, to a device for generating vibration by electromagnetic force. Background technique [0003] As a component that converts electrical energy into mechanical vibration using the principle of generating electromagnetic force, a vibration motor is installed in a mobile phone for silently notifying a user to answer a call by transmitting vibration to the user. [0004] According to the rapid development of the mobile phone market and the trend of multifunctionality of mobile phones, there is a demand for mobile phone components that are compact in size and high in quality. Under such circumstances, there has been an increased demand for development of...
