• a frame;
• a vibration unit fixedly connected to the frame;
• a magnetic circuit unit having a magnetic gap;
• and
• a screen cloth, wherein
• the vibration unit comprises a diaphragm fixed to the frame, and a voice coil inserted in the magnetic gap;
• the magnetic circuit unit comprises a carrier, a first main magnet provided at a side of the carrier toward the diaphragm, an auxiliary magnet provided on a periphery of the first main magnet and defining the magnetic gap with the first main magnet, and a magnetic conductive plate provided at a side of the auxiliary magnet toward the diaphragm;
• and the magnetic conductive plate is fixed to the frame;
• and
• the magnetic conductive plate comprises a first central portion and a first edge portion that abuts to an edge of the first central portion;
• the auxiliary magnet is located at the first central portion;
• the first edge portion is provided with a through hole;
• the screen cloth is provided at a side of the carrier away from the diaphragm and comprises a second central portion and a second edge portion that abuts to an edge of the second central portion;
• the second edge portion is arranged opposite to the first edge portion along a vibrating direction of the diaphragm;
• and the second edge portion is provided with a first groove recessed toward the magnetic conductive plate, corresponding to the through hole.
