Abstract
The present application provides a multifunctional sounding device including a housing with an accommodating cavity and a sounding driver including a basket frame, a vibration system fixed to the basket frame, and a magnetic circuit system configured to drive the vibration system to vibrate along a first direction to generate sound. The multifunctional sounding device further includes a coil configured to drive the sounding driver to vibrate along the second direction, an elastic connecting member, and a flexible sealing film. The housing includes an upper cover body, a lower cover body, and a side wall. The side wall is provided with a sound-emitting hole. The flexible sealing film includes an annular body portion and an extension portion. The solution employs a method of vertically arranging the sealing film, thereby simplifying the molding and assembly process of the sealing film while achieving dual functionality of sound playback and vibration feedback.
