Abstract
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.
