摘要： The present disclosure is related to a vibration motor. The vibration motor includes a housing, a vibrator, a stator and an elastic part. One of the vibrator and the stator includes a coil, and the other includes a magnet opposite to the coil. The elastic part includes a first fixation part, a second fixation part and a connecting part. A weight includes a first side and a second side and a gap part formed by denting towards the direction far from a first side wall from the first side. The weight further includes a welding part protruding from the center of the gap part and extends to the edge of the gap part. The durability of the elastic part is accordingly increased, and the reliability of the product is thus improved.

摘要： A linear vibration motor includes a housing; an elastic connecting part connected with the housing; a vibrator supported by the elastic connecting part and suspended in the housing; a first permanent magnet positioned by an internal wall of the housing; and a second permanent magnet assembled with the vibrator and facing the first permanent magnet. The first permanent magnet and the second permanent magnet are separated from each other. The first permanent magnet and the second permanent magnet are such configured that the same polarities of the first and second permanent face to each other for producing a repulsive force between the vibrator and the housing.

摘要： A linear vibration motor is disclosed. The linear vibration motor, includes a housing provided with an accommodation space; a vibrator accommodated in the accommodation space; and an electromagnet accommodated in the accommodation space. The vibrator includes a weight having a through-hole and a plurality of permanent magnets engaging with an inner wall of the through-hole. A number of elastic connecting parts are accommodated in the accommodation space, one end of the elastic connecting part connected with the housing and the other end connected with the weight for suspending the vibrator in the accommodation space. The electromagnet includes an iron core and a coil around the iron core for producing magnet fields interacting with the permanent magnets further for producing attracting and repelling force to drive the vibrator to vibrate.
