A magnetic energy guide angle sound effect type loudspeaker comprises a washer, a voice coil, a T iron, a permanent magnet, a support and a vibrating diaphragm, the edge of the end, extending into the voice coil, of the T iron is provided with a T iron annular lead angle protruding ring, and the T iron annular lead angle protruding ring is structurally characterized in that the edge of the end, extending into the voice coil, of the T iron is provided with a T iron groove, and the edge of the T iron groove protrudes to form the T iron annular lead angle protruding ring. The end, extending into the voice coil, of the T iron is connected with a convex ring pad, and the outer edge of the convex ring pad forms a T iron annular lead angle convex ring. The loudspeaker has the advantages that after the T-iron structure is changed and a magnetic circuit is subjected to reducing means such as contraction and expansion, magnetic energy is provided for the voice coil through the T-iron annular lead angle convex ring, the
