The diaphragm sheet has a domed diaphragm, an annular voice coil housing having a U-shaped section surrounding the diaphragm, an annular damper around the voice coil housing, and an engaging recess formed on the underside of the diaphragm sheet at a peripheral portion of the damper. A voice coil is provided in the voice coil housing, and the voice coil housing is inserted in a gap between the pole and the annular plate. The recess is engaged with an annular projection formed on the plate. A frame is mounted on the plate for securing the damper on the plate.
