1. A multifunctional acoustic device, comprising:
a cover enclosing an accommodating cavity, the cover having a sound hole; and
an acoustic member suspended in the accommodating cavity, the acoustic member comprising:
a housing with a space;
a vibration system having a diaphragm received in the housing, the diaphragm dividing the space of the housing into a front acoustic cavity and a rear acoustic cavity;
a magnetic circuit system driving the diaphragm to vibrate and generate sounds along a first direction;
wherein the multifunctional acoustic device further comprises a sound channel communicating the sound hole with the front acoustic cavity and a sealing element located at the sound hole and the sound channel, the sealing element is arranged on a peripheral side of the sound channel so that the acoustic member communicates with an outside only through the sound channel; the sealing element comprises an outer fixing frame mounted with the cover, an inner fixing frame mounted with the sound channel, and a flexible connector connecting the outer fixing frame and the inner fixing frame.
