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： The present invention provides a multifunctional sounding device including a housing, a first vibration system, a second vibration system, a magnetic circuit system, an elastic component and a flexible circuit board. The elastic component includes a deformation part fixed to the second vibration system and an installation part extended from both ends of the deformation part and fixed to the housing. The second vibration system is suspended in the containment cavity through the elastic component. The flexible circuit board is connected with the elastic component, so that the vibration of the flexible circuit board is coupled with the vibration of the elastic component. Therefore, the damping of the elastic component is reduced, the force received by the elastic component during vibration is reduced, and the service life of the elastic component is extended.
