1. A multifunctional sounding device, including:
a housing with a containment cavity;
a first vibration system movable along a first direction relative to the housing;
a second vibration system connected to the housing and movable along a second direction and/or in a third direction relative to the housing; the second direction being perpendicular to the first direction, and the third direction being perpendicular to both the first direction and the second direction;
a magnetic circuit system connected with the housing for driving the first vibration system and the second vibration system;
an elastic component including a deformation part fixed on the second vibration system and an installation part extended from both ends of the deformation part and fixed on the housing for suspending the second vibration system in the containment cavity; and
a flexible circuit board including an attached part attached to the deformation part and an extension part bent and extended from the attached part and at least partially located outside the containment cavity.
