Linear vibration motor

A linear vibration motor, including:

• a shell with a first receiving space;
• a vibrator in the shell;
• a stator in the shell;
• one of the vibrator and the stator including a solenoid;
• the other of the vibrator and the stator including a magnetic circuit structure, the magnetic circuit structure having a first magnet and a second magnet respectively arranged at two ends of the solenoid, a third magnet and a fourth magnet respectively arranged on two sides of the solenoid;
• a magnetic conductive frame including a second receiving space, a rectangular bottom wall arranged parallel to a vibration direction of the vibrator, a side wall extending from a periphery of the bottom wall, and a through hole penetrating the bottom wall;
• wherein
• the bottom wall comprises two first sides arranged opposite to each other and two second sides connected to the first side and arranged opposite to each other;
• the side wall comprises a first side wall extending from the first side in a direction perpendicular to the vibration direction, a second side wall extending from the second side in the direction perpendicular to the vibration direction, a third side wall extending from two sides of the through hole in the direction perpendicular to the vibration direction for being parallel to the second side wall;
• and
• the first magnet and the second magnet are respectively fixed on inner surface of the two third side walls, and the third magnet and the fourth magnet are respectively fixed on inner surface of the two first side walls.
