1. A sound-producing device, comprising:
a housing having an accommodating room including a magnetic circuit system;
a voice coil including a bobbin, a voice coil body wound outside the bobbin, and a bottom end suspended in a magnetic gap of the magnetic circuit system;
a conductive member having a first connecting part fixed to the voice coil, a second connecting part fixed to the housing, and an elastic part located therebetween;
wherein the conductive member is integral with a root region of the voice coil body, the magnetic circuit system includes an avoidance part corresponding to the conductive member; the voice coil includes an inner conduction structure, the housing includes an outer conduction structure in electrical conduction with an external circuit; and the first connecting part of the conductive member is adapted for electrical connection with the inner conduction structure to pass through the avoidance part of the magnetic circuit system and extend to the housing, and is electrically connected with the outer conduction structure.
