Title:
VOICE COIL PROVIDED WITH MULTIPLE INDEPENDENT CURRENT INPUT ENDS AND MULTIPLE INDEPENDENT CURRENT OUTPUT ENDS
Document Type and Number:
WIPO Patent Application WO/2017/219743
Kind Code:
A1
Abstract:
Disclosed in the present invention is a voice coil provided with multiple independent current input ends and multiple independent current output ends. The voice coil provided with multiple independent current input ends and multiple independent current output ends is controlled by an ICE chip and is a closed coil. The closed coil is wound by using the following steps: a, synchronously arranging at least two enameled wires side by side to form multiple flat cables, the enameled wires being independent and insulated from each other; b, winding the multiple strands of flat cables to form the closed coil, each enameled wire being provided with a separate current input end and a separate current output end; and c, under the control of an ICE chip, allowing the enameled wires to jointly form multiple-input multiple-output electrical connection ends, which are respectively corresponding to vibration driving controls of sounds having different frequencies, different sound frequencies being driven by different enameled wires. In the implementation of the present invention, due to arrangement of separate current input ends and separate current output ends on enameled wires, the impact of inertia generated during diaphragm vibration and the impact of frequencies and currents, on sound during volume and timbre conversion are reduced, thereby remarkably improving sound quality of sound produced by a loudspeaker.
