The top plate includes an incision on a horizontal rear surface thereof and a horizontal part adjacent to the incision. A diaphragm system is provided over the top of the center pole and includes a dome-like diaphragm, a cylinderical bobbin on which a voice coil is wound, and a brim-like suspension which extends outwardly from the bobbin. A guide ring is bridged between a ledge on a vertical surface of the center pole and the incision of the top plate. The periphery of the suspension of the diaphragm system is fixedly sandwiched between the horizontal part of the guide ring and the horizontal surface of the top plate.
