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.
A multifunctional sounding device, including:
The multifunctional sounding device as described in 1, wherein the extension part includes a first bending part located outside the containment cavity, a second bending part connected to the first bending part and extending in a curved and folded manner along the second direction part and a third bending part connected to the second bending part and extending in a curved and folded manner along the first direction;
