PURPOSE: A slim speaker is provided to replace the functions of a lead wire and a terminal by controlling a voice coil. CONSTITUTION: A magnetic circuit unit generating a magnetic force is successively installed at an empty space of a frame(111). A voice coil(115) is installed on one side of the magnetic circuit unit. The voice coil vibrates with action with the magnetic circuit unit. A diaphragm(117) is installed on the outer surface of the voice coil. One end of an edge(130) is installed on the boarder of the frame. The other end of the edge is installed on the boarder of the diaphragm. One end of an edge damper(140) is installed on one side of the frame. The other end of the edge damper is attached to the boarder of the diaphragm. The edge damper suppresses the movement range of the voice coil. |
