Abstract: A multifunction apparatus, comprising an outer housing and a vibration system, a magnetic circuit system and an elastic supporting member. The magnetic circuit system is fixed by the elastic supporting member and is suspended inside the outer housing. The vibration circuit system comprises a diaphragm and a voice coil. The elastic support member comprises a first fixing portion and a second fixing portion having different heights, and a deformation portion connected with the first fixing portion and the second fixing portion. An orthographic projection of the elastic supporting member in a vibration direction is a polygon or an oval shape. The first fixing portion or the second fixing portion is located at an edge of the elastic supporting member, and four straight edges of the first fixing portion or the second fixing portion are disposed corresponding to a rectangular bottom wall of the magnetic circuit system or the outer housing. The elastic supporting member of the invention does not occupy a horizontal space of the magnetic circuit system, and thus a magnet with large size can be accommodated, and a BL value of a vibrating sound-producing apparatus can be increased; further, since the elastic supporting member is a three-dimensional structure, the length and width of the deformation portion is not limited, facilitating adjustment of an F0 value of the vibrating sound-producing apparatus.
