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.
