Abstract
A vibration motor includes a housing, a vibrator accommodated in the housing to reciprocate in a lateral direction inside the housing, and a pair of elastic members supporting the vibrator inside the housing to allow reciprocation of the vibrator in the lateral direction. Each of the pair of elastic members is a metal plate including a first fixture fixed to the vibrator and a second fixture fixed to the housing. The first fixture and the second fixture are bent in a same direction and face each other in a font-rear direction. The first fixture and the second fixture include a pair of bends extending inward. The pair of bends face each other in a vertical direction.
