Abstract
A linear vibration motor comprises: a motor housing, a stator, a vibrator, and at least two sets of elastic support assemblies for suspending the vibrator in the motor housing and for supporting the vibrator and providing an elastic restoring force. The elastic support assemblies are located between the inner wall of the motor housing and the vibrator, each set of the elastic support assemblies comprising at least two elastic supports. The elastic support comprises a first connection point fixedly connected to the vibrator and a second connection point fixedly connected to the inner wall of the motor housing. The second connection point is coupled to a side wall of the motor housing parallel to the vibration direction of the vibrator. The first connection point and the second connection point of the elastic support are located at the same side of the central axis of the vibrator parallel to the vibration direction of the transducer. The structure of the linear vibration motor is simplified, the vibration support assemblies have better vibration effect, and give the user a good experience.
