Abstract

PURPOSE:To suppress resonance of an edge to its minimum limit, by sticking or applying a material whose internal loss is large, onto the circumferential part of the edge of a loudspeaker of which the edge and a dome are formed to one body by resin. CONSTITUTION:On the circumferential part of an edge 1 of a loudspeaker of which the edge 1 and a dome 2 are formed to one body by resin is stuck or applied a material 9 whose internal loss is large, such as an adhesive tape. According to this constitution, a loss of the stuck part becomes large equivalently, Q is resonance of a standing wave in the edge 1 is reduced, and reflection in a clamping point of the outermost circumferential part of the edge 1 is decreased.
