Abstract
The present invention provides a multifunctional acoustic device includes a cover enclosing an accommodating cavity and an acoustic member. The cover has a sound hole. The acoustic member includes a housing, a vibration system having a diaphragm, and a magnetic circuit system driving the diaphragm. The diaphragm divides a space of the housing into a front acoustic cavity and a rear acoustic cavity. The multifunctional acoustic device includes a sound channel communicating the sound hole with the front acoustic cavity and a sealing element located between 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.
