Vibration motor

A vibration motor, comprising:

• a stationary portion, which includes a casing and a coil;
• a vibrating body, which includes a magnet and a weight and is supported to be capable of vibrating in a lateral direction relative to the stationary portion;
• a first elastic member having a plate shape;
• and
• a second elastic member having a plate shape,
• wherein the first elastic member includes a first fastening portion, a second fastening portion, and a first coupling portion,
• wherein the second elastic member includes a third fastening portion, a fourth fastening portion, and a second coupling portion,
• wherein the first coupling portion couples the first fastening portion to the second fastening portion,
• wherein the second coupling portion couples the third fastening portion to the fourth fastening portion,
• wherein the first fastening portion, the second fastening portion, the third fastening portion, and the fourth fastening portion extend in the lateral direction,
• wherein the first fastening portion and the second fastening portion face each other in a longitudinal direction perpendicular to the lateral direction,
• wherein the third fastening portion and the fourth fastening portion face each other in the longitudinal direction,
• wherein the first coupling portion and the second coupling portion each include a plane portion extending in the longitudinal direction when the vibrating body has zero displacement,
• wherein the weight includes
• a first side wall extending in the lateral direction,
• a second side wall extending in the longitudinal direction, and
• a third side wall extending in the longitudinal direction,
• wherein the second side wall and the third side wall face each other in the lateral direction;
• wherein the first fastening portion is fixed to a first side of the first side wall in the lateral direction,
• wherein the third fastening portion is fixed to a second side of the first side wall in the lateral direction,
• wherein the plane portion of the first coupling portion faces the second side wall in the lateral direction,
• wherein the plane portion of the second coupling portion faces the third side wall in the lateral direction,
• wherein the second fastening portion and the fourth fastening portion are fixed to an inner wall surface of the casing extending in the lateral direction,
• wherein the first coupling portion further includes a first curve, which is bent to be oriented in the lateral direction from a first end of the plane portion of the first coupling portion, and a second curve, which is bent to be oriented in the lateral direction from a second end of the plane portion of the first coupling portion,
• wherein the first fastening portion extends in the lateral direction without being bent at a coupled portion between the first fastening portion and the first curve,
• wherein the second fastening portion extends in the lateral direction without being bent at a coupled portion between the second fastening portion and the second curve,
• wherein the second coupling portion further includes a third curve, which is bent to be oriented in the lateral direction from the first end of the plane portion of the second coupling portion, and a fourth curve, which is bent to be oriented in the lateral direction from the second end of the plane portion of the second coupling portion,
• wherein the third fastening portion extends in the lateral direction without being bent from a coupled portion between the third fastening portion and the third curve, and
• wherein the fourth fastening portion extends in the lateral direction without being bent from a coupled portion between the fourth fastening portion and the fourth curve.
