  • Patent number: 8456042
    Abstract: A linear vibrator is disclosed. The linear vibrator includes a cover, a base forming a hollow space together with the cover and defining a plurality of sidewalls, a pair of elastic members received in the hollow space, a weight with a plurality of laterals suspended in the hollow space by the elastic members, and a magnet assembly provided with a plurality of magnetic poles and accommodated in the weight. Each elastic member defines at least a fastening arm comprising a connecting portion, an inner arm extending from one end of the connecting portion for abutting against the lateral of the weight, and an outer arm extending from another end of the connecting portion for abutting against the sidewall of the base. The extending direction of the inner arm and the outer arm of each fastening arm is the same. The magnetic poles of magnet assembly near the coil are opposite to each other. A height of the linear vibrator with the structure can be reduced.
