description A high-power aluminum wire voice coil comprises a framework, a pure aluminum wire wound on the framework and a pure copper wire serving as a voice coil outgoing line, and one end of the pure aluminum wire is electrically connected with one end of the pure copper wire. The outer wall of the framework is provided with a copper foil at the joint of the pure aluminum wire and the pure copper wire, one end of the pure aluminum wire is wound with a connecting copper wire, and one end of the pure aluminum wire wound with the connecting copper wire, one end of the pure copper wire and the copper foil are electrically connected through soldering tin. The principle of the utility model is as follows: the connecting copper wire is wound at the tail end of the welded pure aluminum wire for a plurality of circles and then is welded on the copper foil together with the pure copper wire, the connecting copper wire is tightly contacted with the pure aluminum wire and then tinned, and as the copper can be tinned, the contact
