Abstract: There is provided a diaphragm or a dust cap configured to emit a sound wave and an electrodynamic speaker unit including the diaphragm or the dust cap. The speaker unit is configured so that a great peak dip of sound pressure frequency characteristics due to influence of a divided vibration mode can be prevented and excellent reproduced sound quality can be provided. In the diaphragm or the dust cap, a recessed-raised portion imitating a wing of an insect is formed at least on one surface of a diaphragm portion configured to emit a sound wave. Preferably, the recessed-raised portion is formed based on data obtained by measurement of an actual shape of a wing vein of the insect or data of a Voronoi diagram imitating the wing vein of the insect.

Abstract: The route control method and the route setting device according to the present invention is configured such that a learning unit is prepared for each path, a function form of the learning unit of the path in forwarding a packet is adjusted by having traffic information (packet arrival rate, queue length, and the like) and congestion information (congested or not congested) of this path as teacher data, and when this path is congested, changing to a path with an output of no congestion among the learning units is executed. Thus, since the learning unit optimizes the function form, changing to an alternative path can be immediately executed even when the congestion incidentally occurs on the path.
