1. A multifunctional sounding device, comprising:
a housing;
a speaker unit accommodated in the housing, comprising:
a vibration assembly, configured to vibrate along a first direction for emitting sounds; and
a magnetic assembly, comprising:
a main magnet; and
an auxiliary magnet spaced apart from the main magnet for forming a magnetic gap;
an elastic member fixed to the housing and configured to suspend the speaker unit in the housing;
a flexible sealing membrane assembly connected between the housing and the speaker unit, comprising:
an outer ring fixed to the housing;
an inner ring fixed to the speaker unit; and
a flexible sealing membrane connected between the outer ring and the inner ring; and
a driving coil fixed to the housing and configured to drive the speaker unit for vibrating in a second direction and providing vibrations, comprising:
a first side, which is opposite to and spaced apart from the main magnet in the first direction; and
a second side, which is opposite to the first side in the second direction and is opposite to and spaced apart from the auxiliary magnet in the first direction;
wherein the second direction is perpendicular to the first direction; the outer ring, the flexible sealing membrane and the inner ring are integrally formed.
