Abstract
Disclosed is a multifunctional sounding device which combines functions of emitting sounds and providing vibrations and includes a speaker unit including a vibration assembly including a first ring and a diaphragm vibrating along a first direction and a magnetic assembly including a main magnet and an auxiliary magnet; an elastic member suspending the speaker unit; a second ring surrounding the first ring; a flexible sealing membrane connected between the two rings; and a driving coil driving the speaker unit for vibrating in a second direction. The two directions are perpendicular. The driving coil includes two sides respectively facing the main magnet and the auxiliary magnet in the first direction. The diaphragm, the first ring, the flexible sealing membrane and the second ring are integrally formed, thereby ensuring concentricity of them four and avoiding glue width requirements so as to release spaces.
