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.
