Abstract
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.
