The present invention discloses a loudspeaker, and a manufacturing method and a sound production method therefor. The loudspeaker includes a vibrating diaphragm, a frame, a magnetic loop system, a voice coil, a suspension edge, a connecting member and a limiting part, wherein the magnetic loop system is arranged on the frame. A lower end of the voice coil is coupled to the magnetic loop system. A suspension edge outer side and a suspension edge inner side of the suspension edge extend and are respectively connected to the frame and the vibrating diaphragm, so as to allow the suspension edge to be maintained between the frame and the vibrating diaphragm. The connecting member is configured to connect to the vibrating diaphragm and the voice coil. A limiting outer side and a limiting inner side of the limiting part extend and are respectively connected to the frame and the connecting member, so as to allow the limiting part to be maintained between the frame and the connecting member.
