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.

Abstract: A speaker unit (1) with a speaker frame (9) and two membranes (7, 8) arranged in the speaker frame (9). A first membrane (7) radiates in a major acoustic radiation direction (A) substantially perpendicular to a major plane (9a) of the speaker unit (1). A second membrane (8) has a secondary acoustic radiation direction (B) different from the major acoustic radiation direction (A). Two drive units (2) are positioned within the speaker frame (9), attached to the two membranes (7, 8), and positioned coaxial to each other at the same height in the speaker frame (9). An acoustic duct (6) provides for a closed acoustic channel from the second membrane (8) in the secondary acoustic radiation direction (B) to a secondary surface (6a) of the speaker unit (1) in a same plane as the major plane (9a) of the speaker unit (1).
