Abstract
A loudspeaker unit includes a voice coil, a diaphragm, a damper, a frame supporting an outer edge of the diaphragm and an outer edge of the damper, and a duct projecting from an outer surface of the frame, with air moved by vibration of the diaphragm flowing into and out of the loudspeaker unit through the duct. The frame has an aperture that communicates with a space inside the frame. The duct, serving as a separate member, is attached to the frame so as to cover the aperture. The frame further includes a support tab that projects into the aperture. Link terminals are attached to the support tab. Before the duct is attached to the frame, lead wires extending from the voice coil are formed into a predetermined shape and are then connected to the link terminals in a space within the aperture.
