摘要： 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 front acoustic cavity to an outside of the sound hole and a sealing element located on an outer side of the cover. The sealing element is arranged covering a peripheral side of the sound hole and the sound channel so that the acoustic member communicates with the outside only through the sound channel.

摘要： Disclosed is a sounding device, including a frame, a vibration system, and a magnetic circuit system. The vibration system includes a diaphragm, a framework, a voice coil, and an elastic conductor. The elastic conductor includes an elastic conductor body, a connection arm, and a pad portion. The connection arm includes a first connection portion, a first bending portion, a second connection portion, a second bending portion, and a third connection portion. A covering film is attached to inner and outer surfaces of the connection arm, and the covering film is moved from inside and/or outside surfaces of the first bending portion and the second bending portion. Removal of the covering film reduces the stress on inner and outer surfaces of bent areas, stabilizes bending angles, reduces springback, and makes pad positions precise.
