Claim 0:
1. A linear vibration motor, comprising:
a housing body;
a stator comprising at least two solenoid assemblies with parallel axes, electrifying in a same direction;
a vibrator installed in the housing body, comprising a first magnet assembly being located between two adjacent at least two solenoid assemblies and comprising a first magnet and a second magnet arranged in a row;
an elastic connector suspending the vibrator in the housing body; wherein
magnetization directions of the first magnet and the second magnet are opposite and parallel to an axial direction of the solenoid assembly, an amount of the solenoid assemblies is two; an amount of the first magnet assembly is one and the first magnet assembly is arranged between the two solenoid assemblies, the vibrator further includes a second magnet assembly and a third magnet assembly arranged in parallel with the first magnet assembly; the second magnet assembly includes a third magnet and a fourth magnet arranged in a row; magnetization directions of the third magnet and the fourth magnet are opposite and parallel to the axis direction of the solenoid assembly; a opposite magnetic pole polarity of the third magnet and the fourth magnet is opposite to a opposite magnetic pole polarity of the first magnet and the second magnet the structure of the third magnet assembly is the same as the second magnet assembly; the second magnet assembly and the third magnet assembly are respectively arranged on two outer sides of the two solenoid assemblies.
