Linear vibration motor that vibrates horizontally

Abstract

A linear vibration motor includes a bracket, a coil provided to the bracket, a case for covering the bracket, a mass positioned in the case, at least two or more springs, each of which one end is connected to the mass and the other end is connected to one surface of the case, a magnet coupled to the mass to be integrated therewith and facing the coil, a plate coupled to the mass to be integrated therewith and positioned on the magnet, and a friction reducing part provided on at least one surface of the mass and reducing friction between the mass and the bracket. The mass vibrates in the horizontal direction such that the thickness of the linear vibration motor is not increased but can be manufactured thin. Therefore, it is advantageous in terms of space when the linear vibration motor is arranged in a mobile phone.
