Abstract

See full text

Disclosed are a voice coil and a sounding device using the voice coil. The coil body includes at least two sub coils fixed together in sequence. Each sub coil is provided with an incoming wire end and an outgoing wire end, and forms only one current path from the incoming wire end to the outgoing wire end and flowing in the same direction. The incoming wire ends of the at least two sub coils are welded together to form an incoming area on the coil body. The outgoing wire ends of the at least two sub coils are welded together to form an outgoing area on the coil body. The voice coil and the sounding device can select a wire with a lighter weight and a greater resistance, thereby decreasing a weight of a vibration system of the sounding device and improving a mid-frequency performance of the sounding device.
