Product description

After being moistened with alcohol, the glued surface of the reinforcing paper is attached to the glued surface of the bobbin and the joints of the bobbin are overlapped, so that the upper part of the voice coil is enclosed as a whole and the outgoing line of the coil is fixed. Meanwhile, the bobbin wall on the upper part of the voice coil is thickened, and the strength of the entire voice coil is increased.
