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 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.

摘要： Disclosed is a sounding device, including a frame, a vibration system, and a magnetic circuit system. The magnetic circuit system has a magnetic gap. The vibration system includes a diaphragm, a framework, a voice coil, and an elastic conductor. The elastic conductor includes an elastic conductor body, a first connecting piece and a second connecting piece, a first bending arm and a second bending aim, and a first pad and a second pad. The lead wires are connected to the first pad and the second pad, the first pad and the second pad are disposed on two sides of the framework, the first bending arm is spaced from the second bending arm, and a middle section is used to increase the volumes of first auxiliary magnets, thereby improving the acoustic performance of the sounding device.
