摘要： A vibrating motor includes a housing defining an accommodating space, a vibrating unit accommodated in the accommodating space, an elastic piece elastically suspending the vibrating unit, and a driving assembly accommodated in the housing. The driving assembly drives the vibrating unit to vibrate. The vibrating unit includes a mass block and a rotor fixed to the mass block. The elastic piece and the mass block are integrally formed through stamping. A position precision of the elastic piece is high, which improves a consistency of the vibrating motor, reduces a stress fluctuation of the elastic piece in a vibrating state, and reduces a possibility of fracture and reliability failure thereof. Moreover, two elastic portions disposed on two sides of the elastic piece are consistent, symmetry of a rotor system is improved, a swing degree of the vibrating motor is reduced, and a performance and a yield level thereof are improved.

摘要： A vibration generating device that can make a relatively heavy vibration member produce sufficient vibration. A vibration generating device has: a vibration member; multiple actuators that are connected to the vibration member; and a stationary element that supports the vibration member via the multiple actuators. Each of the multiple actuators comprises: a supporting body to which the vibration member is fixed; a movable element; a first elastic member that is connected to the supporting body and the movable element; and a magnetic drive circuit (a first magnetic drive circuit and a second magnetic drive circuit) that makes the movable element move linearly back and forth relative to the supporting body. The multiple actuators are supported by the stationary element via a second elastic member. The first elastic member and the second elastic member comprise a gelatinous silicone gel or the like.

摘要： 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.

摘要： A vibrator-mounted holder is attached to a casing of a vibration generator which moves a vibrator to generate a vibration when used. The vibrator-mounted holder includes a vibrator, a vibrator retention unit retaining the vibrator, a fixing unit fixed to a casing, and an arm. The vibrator includes a magnet having a plate shape parallel to a horizontal surface and a yoke arranged on the magnet. The arm connects the fixing unit to the vibrator retention unit, and supports the vibrator retention unit in a manner that the vibrator retention unit is displaceable with respect to the fixing unit. The yoke has a projecting portion which is projected downward and fixed to the vibrator retention unit. The arm is connected to a portion, at which the projecting portion is arranged, within the vibrator retention units.
