Multi-strand independent input-output voice coil

Abstract

Disclosed is a multi-strand independent input-output voice coil. The voice coil is a potted coil, which is formed by winding in the following steps: a. forming a multi-strand flat cable by synchronizing and juxtaposing at least two enameled wires; b. winding the multi-strand flat cable to form the potted coil, each enameled wire including independent current input and output ends; and c. under the control of an ICE chip, forming, by the enameled wires together, a multiple-input multiple-output electrical connection end to correspond to vibration drive control of sounds at different frequencies separately. During use, the independent current input and output ends of the enameled wires reduce impact of inertia in vibration of a vibrating diaphragm and impact of a frequency and current on a sound during a change in a volume or tone. Quality of a sound made by the loudspeaker is notably improved.
