Abstract

PURPOSE:To raise a limit frequency of high range reproducing to restrain the peak, by attaching a ring, to which visco-elastic materials are stuck, to or near the inside circumference of a ring-shaped plane diaphragm. CONSTITUTION:A ring-shaped plate diaphragm 1 is fixed to a voice coil bobbin 6, and the diaphragm 1 is supported on a frame 3 through an edge 2 of the outside circumference, and a damper 4 is interposed between the frame 3 and the bobbin 6. A voice coil 5 is wound around the lower part of the bobbin 6, and a magnet 7 is arranged on the inside. An inside speaker or structure material 8 is arranged in the center open hole of the diaphragm 1. Visco-elastic materials 9 are stuck to or near the inside circumference of the diaphragm 1 by application or the like. The ring to which materials 9 are stuck may be attached to or near the inside circumference of the diaphragm 1. Thus, the secondary resonance mode is suppressed to raise the limit frequency of high range reproducing, and the peak is restrained there.
