The device staggers the four tightening screws set on the clamping ring and the height adjustment rods set on the front, back, left and right of the clamping ring, so that the speaker basin frame can be firmly positioned under the action of four tightening pressure plates, and the tightening direction is always toward the position of the positioning concentric rod. The positioning concentric rod and the conical speaker basin frame are concentric shaft rods in the vertical direction, which can ensure that the speaker basin frame can ensure the concentricity between the three when assembling the T-shaped magnet, the permanent magnet and the magnetic cover, thereby avoiding the offset of the generated magnetic field, resulting in uneven distribution of the magnetic field around the voice coil, and polarization phenomenon will occur, affecting the performance of the speaker.
